ABSTRACT:
There is disclosed an improved molding machine and a system for utilizing said machine, wherein central sources of supply are used to provide the operating requirements for the machine, such as high pressure hydraulic fluid, compressed air, cooling water and electic power. The machine disclosed utilizes a stationary platen and a movable platen, with a novel mold clamping arrangement as an integral part of the movable platen assembly. In this regard, said movable platen includes a pair of relatively movable plate members, with a high pressure diaphragm interposed therebetween. On the rearward most plate member there is mounted latching means for fixing the position of said rearward plate member preparatory to pressurizing of the diaphragm. When pressurized, the diaphragm will force the forward most plate member toward the stationary platen to effect the desired preloading of the mold inserts carried by said platens.
