摘要： A penetration hole of plasticized resin is pierced in a screw head, so that the resin may be accumulated in uniform temperature distribution without sacrificing the function of the injection screw. More specifically, a penetration hole 15 of plasticized resin is pierced inside a screw head 13 at the front end of a screw 12 from the front middle to the rear periphery so as to communicate between the screw peripheral parts and the screw head front space. A ring valve 17 for opening and closing a rear opening 15a of the penetration hole 15, and closing the gap around the screw head is fitted to the rear periphery of the screw head 13 so as to be free to move back and forth.

摘要： An injection molding machine equipped with an assembly for vibration processing which efficiently performs processing operations on the resin in the mold with vibration overcomes the restriction of vibration frequency due to the limited response of return springs and due to vibration transfer loss from the vibratory rods to the vibratory plate when operating at a high frequency. The injection molding machine performs both vibration and ejection without an ejector plate by making the vibratory plate serve a dual purpose and thus enable reduction in both mold size and production cost.

摘要： There is provided a preplasticizing injection machine including a resin vent formed in the injection cylinder behind the plunger stroke wherein said resin vent is connected to a pressure reducing device and/or an inert gas feeding machine. The resin entrapped in the clearance prevents gases generated within the cylinder from being exhausted and it may be blackened due to the oxidation thereof. According to the present invention, these problems can be solved by the above construction. Furthermore, a band heater is provided on the outer surface of the cylinder behind the injection plunger stroke over the resin vent to prevent the entrapped resin from being solidified.

摘要： A method of setting molding conditions for an injection molding machine 1 using a mold 2 whose specifications data are unclear included three setting processes. In the first setting process A, by inputting known data into controller 3, the molding conditions based on a data base prepared in advance and said input known data are set. In the second setting process B, injection molding is performed according to prescribed molding conditions pre-selected concerning injection pressure P, injection speed V and the injection start position of screw 4, and then, based on the product just molded, injection pressure P is altered, to set said altered injection pressure P, injection speed V and proper pre-feed measurement value Md as molding conditions. In the third setting process C, injection molding is performed according to molding conditions obtained from said second setting process B, and subsequently, taking into account the findings from the product just molded, said molding conditions are adjusted. In this manner, even an unskilled operator is allowed to undertake setting molding conditions reliably and with great ease for an injection molding machine loaded with a set of molds whose specifications data are unclear.
