Claims

[Scope of utility model registration request]

In a molding machine, a lower mold is provided on the upper surface of a horizontal fixed plate, an upper mold is provided on the lower surface of a movable plate that faces the lower mold from above and is movable up and down, and is formed between the upper mold and the lower mold. a mold clamping cylinder that can freely control the mold clamping force that urges the upper mold toward the lower mold and its holding time, and a shutoff valve that injects molten resin into the cavity and prevents backflow. a main cylinder that is connected to a plunger that moves forward and backward into the cylinder chamber of the injection cylinder, and that can freely control the stroke of the plunger, the injection force of the plunger, and its holding time; A plasticizing cylinder that supplies resin and a flow path from the plasticizing cylinder to the cylinder chamber of the injection cylinder are provided so as to close toward the plasticizing cylinder, and are controlled to open and close in conjunction with the stroke of the main cylinder. A valve, and an upper mold position control cylinder that is fixed to the fixed plate in the vertical direction and that can push up the upper mold against the mold clamping force of the mold clamping cylinder and freely control the height position of the upper mold. A multi-functional molding machine that is characterized by:
