き射出形成機に関する。Detailed Description of the Invention "Industrial Application Field" The present invention is characterized in that the molding material is plasticized and kneaded in the process of being sent forward along the groove of the screw by the rotational transfer action of the screw of an injection molding machine. When a predetermined amount of molten resin is loaded into a pot on the side of a more vertical or horizontal injection plunger, a plunger is inserted into the pot, and as the plunger moves forward, a screw is press-fitted into the cavity of the mold. In the U-plunger type, after the plunger is pulled out from the pot, the inside of the pot can be easily cleaned by moving the plunger laterally along a holding member, and at the same time, the color and material can be easily changed. This invention relates to an injection molding machine with a plunger moving device that can move the plunger.
