    摘要: An injection molding machine, wherein an injection pot (34) with an injection nozzle (33) and a side casting port (35) for casing a material into the pot are formed in a metal case (31), the tip part (37) of a plunger (36) disposed in the pot is formed in such as shape that the tip part (32) of the injection pot can be generally filled with the material when an injection is completed, a fitting part (38) pressingly cutting off a formed material by allowing a boundary part between a plunger body part (34a) and the tip part (37) to be fitted thereto is formed at a boundary part between an injection pot body part (34a) and the tip part (32), and when tip part of the plunger is inserted into the tip part of the injection pot, a clearance S is formed between the tip part (37) of the plunger and the tip part (32) of the injection pot and the casting port (35) is opened to the fitting part (38), whereby the injection molding machine capable of performing the assured pressing cutting off and excellent injection of plastic rubber in the injection pot and effective removal of residual rubber with less number of times of injection and providing an efficient production efficiency and an excellent strength can be provided.

    摘要: In order to eject resin leaked from an injection chamber (13) toward the shaft side of an injection plunger (31) away from an injection cylinder (30), a plunger-type injection molding machine injection device is equipped with an ejection guide (151, 251) at the rear edge of an injection cylinder which is thermally isolated from the injection cylinder main body. A band heater (53), which heats the ejection guide, is controlled independently of the band heater (38) which heats the injection cylinder. One embodiment of this injection guide (151) causes the ejected resin to fall from the ejection opening (151h) while retaining its molten state. In another embodiment, the ejection guide (251) has ejection channels (251f) which cause the resin to harden and be ejected in a fine strand state.
