Definitions
- the invention relates to a molded plastic part which comprises a plastic carrier with a plurality of fields, at least one of these fields being laminated with a covering material and at least one other of these fields being sparkling clean, and to a method and a device for the production thereof.
- a plastic molded part of the type mentioned is known from DE 44 08 446 AI.
- a corresponding method and a corresponding device are also disclosed in this publication.
- the plastic carrier is produced in one piece in a single operation.
- the plastic carrier is uniformly introduced into the mold cavity with very low pressure and a very low flow rate.
- the surface quality in the blank areas can not be optimal in unfavorable cases due to the low pressure.
- air pockets or faulty formations can occur in these areas, which either have to be reworked or, since this is sometimes not possible, lead to rejects in the production of the plastic molded parts.
- Another disadvantage of the known plastic molding is that due to the low pressure and the low flow velocities, in particular with large overall component dimensions, it is sometimes difficult to achieve an even distribution of the plastic carrier in the mold cavity. For the sparkling bright field is a relatively high quality and therefore expensive
- Plastic material required which must also be used in the laminated areas due to the one-piece plastic molded part.
- the object of the invention is therefore to create a molded plastic part of the type mentioned at the outset, which has a uniform, optimal quality in its injection-molded areas and in its areas laminated with a covering material.
- the plastic carrier of the injection-molded field consists of a plastic injected under high pressure
- the plastic carrier of the laminated field consists of a plastic introduced under relatively low pressure and at a low flow rate.
- the high pressure with which the plastic carrier of the injection-molded field is injected achieves a very good surface quality on the visible side of the plastic carrier.
- filigree surface patterns which are used, for example, in vehicles for matting the surfaces, can also be produced reliably and without the risk of air pockets.
- recesses such as for loudspeakers in door panels of motor vehicles. testify, precisely producible, because of the high pressure and the possibly high flow rate of the injected plastic, even complicated geometrical shapes can be injected with high quality.
- the relatively low pressure and the low allow
- this molded plastic part comprises, according to claim 2, several fields laminated with possibly different covering materials, between each of which there is an injection-molded connection field.
- This bare connection field can be made extremely narrow.
- the bare connecting field holds the edge of the cover material securely, and a visually pleasing exterior is created, especially with different cover materials.
- plastic molding according to the invention is characterized in that the plastic carrier of the injection-molded field is made of a high quality plastic and that of the laminated field is made of a less high quality plastic.
- This further development makes it possible to achieve noticeable cost savings, since an expensive plastic material is only used for the bare injection molding fields, in which the plastic carrier remains visible on the visible side of the finished plastic molded part, whereas the laminated fields, which often have a large part of the Identify the plastic molded part and its plastic carrier on the visible side of the finished plastic molded is partially covered by the cover material, an inexpensive plastic material is used.
- a particularly durable and high-quality design of a molded plastic part is disclosed in claim 4: Thereafter, the protruding edge of the covering material of the laminated field is extrusion-coated by the plastic carrier of the adjacent, blank area.
- This bare injection-molded field can also be an injection-molded connection field to which a further field, which may be covered with different covering material, adjoins. This further development reliably prevents the covering material in the edge region of the laminated field from detaching from the plastic carrier during the service life of the molded plastic part.
- edges of the covering material are determined so that the mold cavity of the laminated field is tightly separated from the other fields;
- the plastic carrier of the laminated field is first and then the plastic Fabric carrier of the splash-free field made.
- the mass cake is introduced into the mold cavity of the laminated field in a relatively flat manner over the base area of the die.
- the method according to claim 8 is particularly cost-effective if the molding of the mass cake in the mold cavity of the laminated field is carried out by closing the molding tool clamped on a normal press.
- the method can also include the work steps in the following order:
- the mass cake is introduced into the mold cavity of the laminated field via a low-pressure nozzle, since this enables the mass cake to be introduced particularly quickly.
- This nozzle is preferably a wide slot nozzle.
- the molding of the mass cake in the mold cavity of the laminated field is carried out according to claim 11 via a press ram, the flow rates being kept low and the pressure on the mass cake being controlled very well.
- the invention is based on claim 12
- At least one frame slide which can be moved through into the mold cavity and with which the edge of the covering material can be fixed along at least part of the boundary of the laminated field; d) at least one nozzle through which the melt of the plastic carrier can be introduced;
- the molding tool is integrated in a press with two parts which are movable relative to one another;
- the first die is movable parallel to the press stroke and is supported by a spring element against one part of the press, the maximum spring travel of the spring element being smaller than the maximum press stroke;
- the second die is connected to the other part of the press.
- the particular advantage of such a device according to the invention is that the molding tool is installed in a normal press, so that the costs for producing such a device are significantly reduced.
- all the steps of the method according to the invention can be carried out in this one device, which further reduces the manufacturing costs of the molded plastic part.
- the spring element is a spring cushion, because this enables the high support forces to be absorbed particularly well, the spring force of the spring cushion being sufficiently constant over the entire spring travel.
- the nozzle which introduces the melt into the mold cavity of the laminated field, is integrated in the press ram.
- the press ram can take up a large area, so that the stroke of the press ram, which is necessary for pressing the mass cake, can be kept low.
- the object of the invention is also to provide a device which is particularly suitable for carrying out the method according to one of claims 5 to 7.
- the device according to the invention is based on a system with a molding tool, which comprises
- the molding tool is integrated in a press with two parts which are movable relative to one another;
- the first die is connected to one and the second die to the other part of the press;
- a robot which applies the mass cake to the mold cavity of the laminated field almost without pressure and relatively flat over the base area.
- An advantage of this device is that the molding tool itself can be of a very simple design and can therefore be manufactured inexpensively. In addition, installation in a conventional press is possible in a simple manner. Finally, the use of a robot to apply the mass cake enables it to be spread over a relatively large area, so that when the mass cake is pressed, it only has to travel short distances and low flow rates can thus be achieved.
- the injection unit is over a deflection device is connected to the channel, which has an input to the injection unit and a plurality of switchable, vertically differently arranged channel-side outputs.
- the mold can be installed in a vertical press or in a horizontal press.

- Fabric carrier applied to the top of the lower die part 38 in the areas of the laminated fields 18 and 20. The application takes place, for example, in serpentine-like strands in order to cover the mass cakes 68 during the later pressing process
- the material of the plastic carrier is an inexpensive plastic material that may no longer be very thin.
- the upper part 14 of the die is slowly moved downwards by the movable part of the vertical press. In this case, the upper part 14 of the die initially comes with the clearly above
- Mass cake 68 completely filled. Through the guide pin 62 and the bore 68 with the insert 66, the movement of the upper die part 14 relative to the lower die part 38 is guided with a precise fit.
- Hot melt (not shown) of a high-quality plastic carrier is now injected into the mold cavities of the injection-molded panel 22 and the connecting panel 30 under high pressure via the needle shut-off nozzles 50 and 60 (not visible in FIG. 3).
- the hot melt is provided by an injection unit (not shown) which is coupled to the mouth of the horizontal channel 54 in the lateral end face 56.
- the exposed edges of the covering materials 24 and 26 of the laminated fields 18, 20 are extrusion-coated by the melt and held securely after their solidification.
- the edges of the solidified mass cake 68 of the laminated fields 18, 20 are melted again by the hot melt, whereby a good connection between the individual fields is achieved.
- the upper die part 14 is moved vertically upwards by the movable part of the press, so that the finished plastic molded part can be removed.
- FIG. 4 in which a second exemplary embodiment of a molding tool for producing a plastic molded part is shown. Those parts which correspond to those of the first exemplary embodiment are not explained again below and are provided with the same reference numerals as in FIGS. 1 to 3, plus 100.
- vertically movable pressing dies 170 and 172 are present in the regions of the lower die part 138 which are assigned to the fields 118 and 120 laminated with covering materials 124 and 126.
- a low-pressure wide-slot nozzle 174, 176 is arranged in each of the press dies 170, 172.
- the low pressure wide slot nozzles 174 and 176 are connected to the horizontal channel 154.
- a separate horizontal channel is provided for the low-pressure wide-slot nozzles 174, 176.
- the press rams 170, 172 are attached to the lower connecting plate 132 essentially rigidly via rods 178, 180, at least in the vertical direction.
- the rods 178, 180 are passed through through bores 182 through a support plate 184 which is supported on the lower connecting plate 132 via a spring cushion 186.
- the intermediate plate 136 is not attached to the lower connecting plate via the supports 134, as in the first exemplary embodiment, but to the support plate 184.
- a guide bore 188 is present in the left carrier 134, into which an insert 190 is inserted.
- a guide pin 192 is attached to the lower link plate 132 and slidably received in the insert 190.
- the molding tool 110 is used as follows:
- the upper connecting plate 112 is connected to the movable part and the lower connecting plate 132 to the stationary part of a vertical press.
- the upper die part 114 is slowly lowered until the areas of the upper die part 114 and the lower die part 138 lying outside the mold recess 116 touch each other essentially without force.
- the spring cushion 186 thus remains in its maximally rebounded position, i.e. that the lower die part 138 is held in a vertically upper position via the supports 134 and the intermediate plate 136.
- the length of the rods 178 and 180 and the length of the spring cushion 186 in the unloaded state are coordinated with one another such that in this state the press rams 170 and 172 are in a slightly retracted position relative to the wall of the mold cavity 116 of the lower die part 138.
- edges of the covering materials 124 and 126 are now defined by the frame slides 142, 144 and 158 so that the mold cavities of the laminated fields 118 and 120 are separated from the injection-molded field 122 and the connecting field 130 are tightly separated.
- the melt of a high-quality plastic (not shown) is brought via the channel 154 to the needle valve nozzles 150 and 160 and from there is injected under high pressure into the mold cavities assigned to the injection-molded field 122 and the connecting field 130.
- the high pressure and the high quality of the plastic material ensure a high surface quality of the blank 122 and the connection field 130 on the finished molded plastic part.
- the edges of the covering materials 124, 126, which protrude into the bare squares 122, 130 via the frame slides 142, 144, 158, are extrusion-coated by the melts and, after their solidification, are held in place by the resulting plastic carrier.
- the frame slides 142, 144 and 158 are retracted by the hydraulic unit 148 and the linkage 146. Now the material of the plastic carrier of the laminated fields 120 and 118 is fed to the low-pressure wide-slot nozzles 174 and 176 via the channel 154.
- the mass cakes (not shown) are introduced into the mold cavities assigned to the laminated fields 118, 120 almost without pressure via these low-pressure wide-slot nozzles 174, 176.
- the press is then actuated in such a way that the upper die part 114 moves downward, thereby pushing the lower die part 138 downward against the spring force of the spring cushion 186 via the intermediate plate 136, the supports 134 and the support plate 184.
- the movement of the lower die part 138 is guided via the guide pin 192.
- the upper die part 114 becomes together with the lower die part 138 moved downward relative to the press rams 170, 172, which are essentially rigidly attached to the lower connecting plate 132.
- the mass cakes in the mold cavities of the laminated fields 118, 120 are pressed until the mold cavities are completely filled.
- the bulk cakes are preferably pressed at a point in time at which the melt in the mold cavities of the injection-molded field 122 and the connecting field 130 has not yet cooled completely, so that there is a good connection between the plastic carriers of the laminated and the plastics -Beams of the bare fields is achieved.
- the upper press part with the upper die part 114 attached is retracted so that the plastic molded part can be removed.
- the injection unit (not shown) is connected to the horizontal channel 154 introduced in the vertically displaceable lower die part 138 via a deflection device (not shown) which has an input to the injection unit and a plurality of switchable, vertically different high channel-side outputs.
