Definitions

  • the present invention relates to a two-station die-casting apparatus having a single furnace, for the automatic die-casting of brass, with a low pressure process.
  • die-casting is a particular type of casting, in which the castings are formed in permanent metal moulds, sometimes called “shells” but more usually “dies”.
  • the object of the present invention is to eliminate the previously discussed disadvantages and to provide apparatus for the automatic die-casting of brass, which allows a better and fuller exploitation of the operating capacity of a furnace to be obtained.
  • An advantage of apparatus according to the invention is that it allows the production of small, medium and large pieces to be obtained with an automatic brass die-casting process.
  • Another advantage of the present invention is that it provides a system of automatic die-casting of brass which is made in such a way that it does not require the pro ⁇ vision of a foundation to put it in operation.
  • apparatus for the automatic die-casting of brass characterised by the fact that it includes two pairs of die-carrier heads which can be turned through 180° about a central vertical axis in such a way as to be positioned either in front of a furnace or in front of an operator, each die-carrier head being controllable independently of the other and being capable of turning movement about three mutually orthogonal axes.
  • the apparatus shown includes two die-carrier heads 1 and 2, which are mounted on a common support capable of rotation through 180° about a central vertical axis 3, in such a way that the heads 1 and 2 can be carried either to a position in front of a furnace or to a position in front of an operator 5.
  • each die-carrier 6 is mounted rotatably on a support structure 7 and each support structure 7 is slidably mounted on a bed 8.
  • Two fluid pressure actuators 9 are provided for displacing the support structures 7 slidably on the bed 8 in a direction transverse the length of a line joining the two sets of die-carriers heads 1, 2 and passing through the common central vertical axis 3.
  • Each bed 8, in turn, can be inclined by the action of an appropriate actuator 10.
  • a graphiting vessel 11 is arranged at the operator's position and is provided with an automatically controlled heating and cooling system.
  • Each bed is mounted by means of bracket elements 13 so as to be turnable about an axis 12 and can be turned about this axis by the action of a double acting fluid pressure actuator 14 (see Figure 3).
  • each die-carrier head is controllable in an independent manner and is able to perform the following operations:
  • the pressurisation system for the casting chamber is supplied from a compressed air network and is constituted, essentially, by:
