摘要： An injection molding apparatus for injecting resin into a mold comprises an injection cylinder in fluid communication with the mold, wherein movement of a piston relative to the cylinder injects a selected quantity of resin into the mold. A plasticizing unit includes a flighted screw rotating in a heated containment barrel for plasticizing resin. The plasticizing unit is in fluid communication with the injection cylinder for supplying the injection cylinder with plasticized resin. A valve is provided for selectively placing the injection cylinder in fluid communication with the mold and placing the plasticizing unit in fluid communication with the injection cylinder, wherein the valve exerts pressure on resin in the mold independently of the injection cylinder or plasticizing unit.

摘要： An injection molding machine includes a plasticating unit for plasticating a thermoplastic resin, and an injecting unit connected to the plasticating unit through a connecting passage to inject the plasticated resin into a mold. In the connecting passage, provided is a buffering unit for reserving the resin in an amount at least equal to the quantity of the resin injected per one shot. The plasticated resin is temporarily reserved in the buffering unit, and then, the reserved resin is fed to the injecting unit when the measuring is carried out, whereby the plasticating unit can be driven continuously simultaneously with the operation of the injecting unit and the mold. The molding cycle can shortened with the plastication efficiency being enhanced.

摘要： An injecting machine for two different liquid material includes an injection cylinder having a nozzle disposed on a distal end thereof. A plunger is reciprocally received in the injection cylinder for undergoing reciprocating movement between an advanced position and a retracted position, with the plunger injecting a liquid mixture of the two different liquid materials as the plunger moves to the advanced position. A moving mechanism causes the plunger to reciprocate between the advanced position and the retracted position. A mixing mechanism is disposed on the injection cylinder for mixing the two different liquid materials together to feed the liquid mixture into the injection cylinder. A support plate supports a proximal portion of the injection cylinder. The mixing mechanism is supported in its entirety by the injection cylinder.

摘要： A plasticizing screw of an injection-molding machine, axially movable in an extruder barrel, is driven by a tubular input shaft via a splined quill partly retractable into the shaft with which the quill is coupled through an internally and externally splined bushing. Another such bushing is removably seated, for possible replacement by a similar bushing of different inner diameter, in an internally splined cup-shaped head of the quill and engages the splined rear end of the screw. The quill head rests via a thrust bearing against the front end of a nonrotatable tubular piston coaxially surrounding the quill and entering by its rear end an annular cylinder which is hydraulically connected with a pressure accumulator including a gas cushion. The accumulator creates a back pressure by which molding material, plasticized by the screw during the preceding phase in which the screw was repressed into a rear position, is introduced via a check valve into a shooting pot alongside the extruder barrel. Another tubular injection piston extends rearwardly into an annular injection cylinder, which is pressurized only briefly upon closure of the mold, and bears at its front end upon a plunger penetrating into the shooting pot whose effective capacity is determined by a manually adjustable backstop for the injection piston. Lubricating oil from a sump in a gearbox surrounding the input shaft is pumped by the reciprocation of the quill, through passages provided for this purpose, to spaces inside the input and inside the extruder piston communicating with each other through the splines of the quill.

摘要： A plasticizing and injecting device for a plastics injection molding machine includes an axially fixed and rotationally driven plasticizing screw, and an injection plunger movable forwards and backwards inside the plasticizing screw by a linear drive and including, at its front end, a non-return valve. An injection cylinder is provided anteriorly of the plasticizing cylinder. The non-return valve can be moved by the injection cylinder forwards and backwards inside the injection cylinder between a rear position at the beginning of the injection process and a front position after completion of the injection process. In addition, a melt chamber is formed between the front end of the plasticizing screw and the non-return valve, and forms, during the injection process and during the holding pressure phase, an annular gap between the injection plunger and the injection cylinder for receiving plastic melt as the plasticizing screw continues to rotate during injection.
