Abstract

The invention provides a screw pre-plasticization injection molding machine, and belongs to the field of injection molding machines. According to an existing screw injection molding machine, control over the injection volume is not accurate, and no special waste feeding device is arranged on the existing screw injection molding machine. The screw pre-plasticization injection molding machine comprises a screw pre-plasticization machine and a plunger injection machine. The screw pre-plasticization machine is fixed to the plunger injection machine through a frame. The screw pre-plasticization machine comprises a screw pre-plasticization machine barrel, a screw arranged in the screw pre-plasticization machine barrel, a driving device for driving the screw, and a new material feeding bucket and a waste feeding bucket arranged on the screw pre-plasticization machine barrel. A heater is arranged outside a heating section of the screw pre-plasticization machine. A discharge port of the screw pre-plasticization machine is connected with the plunger injection machine through a one-way valve. The plunger injection machine includes a plunger injection machine barrel, a plunger, a hydraulic drive device for driving the plunger, and an injection head at a discharge port of the plunger injection machine. The injection volume is easy to control by separating pre-plasticization from injection. The waste can be recycled by arranging the waste feeding bucket, and the feeding amount is stable.

Description

technical field [0001] The invention belongs to the field of injection molding machines, and in particular relates to a screw premolded injection machine. Background technique [0002] Injection molding machine is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Screw-type injection molding machines are widely used. With the help of the thrust of the screw, the plasticized plastic in the molten state (ie, viscous fluid state) is injected into the closed cavity, and the product is obtained after curing and shaping; but there is an injection volume Control imprecise problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a screw pre-plastic injection machine which is easy to control the injection volume and can reuse waste materials. [0004] The technical scheme that the present invention takes is: [0005] A sc...
