Vertical Disc Injection Molding Machine
The working principle of the disc Vertical Injection Molding Machine is to use the thrust of the screw (or plunger) to inject the plastic in the molten state (i.e. viscous flow state) after plasticization into the closed cavity, and then get the product after solidification.
Injection molding is a cycle process, each cycle mainly includes quantitative feeding, melt plasticity, pressure injection, mold filling cooling and mold opening. Take out the plastic part, and then close the mold for the next cycle.
Generally speaking, the molding process of the screw disk injection vertical Injection Molding Machine is as follows: first, add granular or powdered plastic into the cylinder, melt the plastic through the rotation of the screw and the heating of the outer wall of the cylinder, then close the mold, move the injection seat forward, make the nozzle close to the pouring port of the mold, and then inject pressure oil into the injection cylinder to push the screw forward, so that the high pressure can inject the melt into the closed mold with a relatively low temperature at a faster speed. After a certain period of time and pressure maintaining (also called pressure maintaining) cooling, solidify it into shape, and then open the mold to take out the product (the purpose of pressure maintaining is to prevent the melt from flowing in the mold cavity in reverse, supplement the mold cavity material, and ensure that the product has a certain density and dimensional tolerance). The basic requirements of injection molding are plasticization, injection molding and molding.
