Structural parts of injection mold

    It refers to the various parts that make up the mold structure, including: various parts for guiding, stripping, core pulling, and parting. Such as before and after the splint, front and rear buckle template, bearing plate, pressure column, guide column, stripping template, stripping rod and return rod and so on.

1.Guide member

  In order to ensure accurate centering of the movable and fixed molds during mold clamping, guides must be provided in the mold. In the injection mold, four sets of guide columns and guide bushes are usually used to form the guide parts. Sometimes it is also necessary to set the inner and outer taper surfaces on the movable mold and the fixed mold respectively to assist positioning.

2. Launch agency

    In the mold opening process, an ejector mechanism is required to push or pull out the plastic products and their aggregates in the flow path. The fixed plate and the push plate are pushed out to hold the push rod. In the push rod, a reset rod is generally fixed, and the reset rod resets the push plate when the movable and fixed molds are closed.

3. Side pull core mechanism

     Some plastic products with undercuts or side holes must be laterally typed before they are pushed out. After the lateral cores are pulled out, they can be demolded smoothly. At this time, the side core-pulling mechanism needs to be set in the mold.
