Injection Mold Composition And Function

- Oct 25, 2017 -

The injection mold consists of seven parts: molding part, pouring system, guiding mechanism, ejector, lateral type and core pulling mechanism, cooling heating system and exhaust system.

First, forming parts

Injection molding parts are parts that make up the mold cavity, mainly include: punch, die, core, forming rod, forming ring and inserts and other parts.

Second, pouring system

Injection mold pouring system refers to the mold from the injection molding machine nozzle to the cavity until the plastic flow channel. Ordinary pouring system is composed of main channel, shunt, gate, cold material and so on.

Third, the guiding institutions

Injection mold guide mechanism, the main positioning, guidance, to withstand the role of a certain side of the pressure to ensure that dynamic and fixed mold die accurate. The clamping mechanism consists of a guide post, guide sleeve or guide hole (directly on the template), positioning cone and other components.

Four, out of the device

Injection mold out of the device mainly from the workpiece from the top of the role of the mold, by the top of the jack or pipe or push plate, the top plate, the top of the fixed plate, reset rod and pull rod and so on.

Five, lateral classification and core pulling mechanism

The role of the injection mold side-by-side and the core pulling mechanism is to disengage the lateral punch or out of the lateral core, which typically includes a diagonal guide, a bending pin, an inclined guide groove, a wedge block, an oblique block, , Rack and pinion and other parts.

Six, cooling heating system

Injection mold cooling The role of the heating system is to adjust the mold process temperature, by the cooling system (cooling water hole, cooling sink, brass) or heating system.

Seven, exhaust system

Injection grinding machine exhaust system role is to remove the gas within the cavity, mainly by the exhaust slot, with the gap and other components.
