Description

Injection molding machine

Technical Field

The invention relates to the technical field of switch socket production, in particular to an injection molding machine.

Background

The injection moulding machine is similar to the injection syringe for injection, and is a technological process in which the plasticized plastic in a molten state (i.e. viscous state) is injected into a closed mould cavity by means of the thrust of a screw (or a plunger), and the product is obtained after solidification and shaping. Injection molding is a cyclic process, each cycle consisting essentially of: quantitative feeding, melting and plasticizing, pressure injection, mold filling and cooling, mold opening and mold taking. And taking out the plastic part, closing the mold again, and performing the next cycle.

The injection molding machine generally comprises an injection device, a mold closing device, a hydraulic system, an electric control system and the like. The basic requirements of injection molding are plasticization, injection and molding. Plasticization is a prerequisite for achieving and ensuring the quality of the molded product, and in order to meet the molding requirements, sufficient pressure and speed must be ensured for injection. Meanwhile, because the injection pressure is high, correspondingly high pressure is generated in the die cavity (the average pressure in the die cavity is generally between 20 and 45 MPa), and therefore, a sufficient mold clamping force is required. It follows that the injection unit and the clamping unit are key components of the injection molding machine.

Injection molding machines are classified into plunger type injection molding machines and screw type injection molding machines according to plasticizing modes, hydraulic type, mechanical type and hydraulic-mechanical (connecting rod) type according to transmission modes of machines, and are classified into automatic, semi-automatic and manual injection molding machines according to operation modes.
