Definitions
- the die casting machine (in the following called only “machine”) produces, by means of injection moulding, pieces of non ferrous metal alloys melted to a liquid state , such as aluminium, zinc, magnesium, copper, etc.
- Fig. 1/10 shows a traditional horizontal cold chamber die casting machine.
- Figs. 2/10, 3/10- 4/10 are diagrams of the traditional moulding process.
- the injection system generates in the mould pressure in the range from 200-1200 bars plus overpressure caused by the discharge of kinetic energy of the masses in movement on the inj ected liquid metal.
- the masses are formed by: injector piston, piston holder, injection cylinder stem, oil and accumulator pad Fig 1/10
- the machine mentioned in the title is very similar to a traditional machine for cold chamber die-casting.
- the power of thrust of the secondary cylinder is maintained constant during withdrawal, by the aid of one or two pressure limiters connected to the cylinder.
- the secodary cylinder is used as a pressure limiting device in the mould.
- the secondary cylinder can, if necessary, immediately start the compression phase, applying higher power through an oledynamic/electric circuitwhose start is given by the position of the primary cylinder Fig. 10/10 to complete the production cycle.
- Figs. 5/10, 6/10, 7/10, 8/10, 9/10, 10/10 show diagrams of the new machine and the new moulding cycle.
- Figs. 5/10 and 6/10 show two versions of the double cylinder die casting machine. Note that one is a traditionl cylinder which we have named primary, and the other is the new one which is named secondary.
- Figs 2/10, 3/10, 4/10 show a traditionally performed moulding cycle.
- Fig 1/10 shows a traditional die casting machine with its essential parts indicated.

Abstract
L'appareil de coulage sous pression faisant l'objet de la présente invention produit, grâce à des moyens de coulage par injection, des pièces d'alliages métalliques non-ferreux fondus à l'état liquide, notamment en aluminium, zinc, magnésium, entre autres. Pendant le coulage, les machines effectuent la coulée avec des baisses de pression du système de fermeture, en provoquant ainsi l'ouverture consécutive et la formation de bavures sur les pièces produites. Le nouvel appareil possède un système d'injection à deux cylindres au lieu d'un seul : l'un fonctionne en tant que limiteur de pression et compacteur, l'autre fonctionne en tant qu'agent de transfert de métal liquide de la chambre à la cavité du moule. Ce système élimine les pics de pression dans le moule créés par l'énergie cinétique, lesquels sont responsables de bavures indésirables.
