The basic structure of the shell of the injection mold can be divided into seven parts according to its functions: forming parts, casting system, guiding mechanism, ejection device, side parting and core-pulling mechanism, cooling and heating system and exhaust system. Let's take a look at the composition system of the shell structure of the injection mold.
1, molding parts it refers to the parts of the mold cavity.
Mainly includes: punch, die, core, forming rod, forming ring and insert parts.
2. Gating system it refers to the plastic flow channel in the mold from the nozzle of the injection molding machine to the cavity.
The ordinary pouring system is composed of the main flow way, the shunt way, the gate and the cold hole.
3, the guide mechanism in the plastic mold, mainly positioning, guiding, under a certain lateral pressure, to ensure that the dynamic, fixed die accurate. The mould closing guide mechanism is composed of guide post, guide sleeve or guide hole (directly open on the template) and locating cone.
4. Ejection device is mainly used for ejecting the workpiece from the mold, which is composed of ejector rod, ejector pipe or push plate, ejector plate, ejector fixed plate, reset rod and pulling rod.
5. Side parting and core pulling mechanism.
6. Cooling and heating system.
Exhaust system.
