Abstract

An injection moulding machine for plastics is composed of machine frame, industrial control computer and hydraulic mechanism. On said machine frame, there are vertical mould closing unit with dual knuckle levers, ball-leading screw shift unit, lubricating unit, vacuum pneumatic unit, safety rod unit, injection unit and drier. Its advantages are strong mould-blocking force, instantaneously opening mould, precise position control, and correct dosage for each injection.

Description

Technical field: [0001] The invention belongs to injection molding machines, in particular to a plastic injection molding machine. Background technique: [0002] At present, domestic injection molding machines are mainly disc machines, which are applied to ordinary plastics such as PVC, TPR, PU, ​​etc., because the clamping force required by these ordinary plastics is not high, and the required injection dose control is not very strict; but in recent years The emerging new materials such as EVA materials require very high clamping force and strict injection dose control, and ordinary disc machines cannot meet the requirements at all. Invention content: [0003] The object of the present invention is to provide a plastic injection molding machine, which adopts a vertical double toggle mold clamping mechanism and a ball screw seat shifting mechanism, which improves the mold locking ability and the precise control of the injection dose, and solves the problem of common inject...
