1 injection molding machine definition, components and uses

Injection molding machine definition: injection molding machine (referred to as the injection molding machine or injection molding machine) is a thermoplastic or thermosetting materials using plastic molding mold made of various shapes of plastic products, the main forming equipment. Injection molding is achieved through the injection molding machine and mold.

2, the type of injection molding machine

Injection molding machine types are: vertical, horizontal, all electric, but regardless of the kind of injection molding machine, its basic functions are two:

The heating plastic, to reach the melting state;

We exert high pressure on the molten plastic to make the shot full of mold cavity.

3, the structure and function of the injection molding machine:

Injection molding machine usually by injection system, mold clamping system, hydraulic transmission system, electrical control system, lubrication system, heating and cooling system, safety monitoring system, and so on.

Injection system

Injection system: injection system is one of the most important parts of the injection molding machine, there are 3 main types: plunger type, screw type, and screw injection molding. At present, the most widely used is the screw type. Its role is in plastic injection machine of a cycle, within the specified time will the number of plastic heating plasticization, under certain pressure and velocity, by means of a screw will molten plastic into the mold cavity. After the injection is finished, the melt in the mold cavity is maintained.

Composition of the injection system: the injection system is composed of a plastic unit and a power transmission device. The screw type injection moulding machine is mainly composed of a feeding device, a material barrel, a screw and a nozzle. The power transmission device comprises a cylinder, a moving cylinder injection injection and screw drive (SOL motor).
