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.
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 necessary to set the inner and outer taper surfaces that are matched with each other on the movable mold and the fixed mold to assist positioning.
2. Launch agency
In the mold opening process, an ejector mechanism is required to push or pull the plastic product and its aggregate 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 pulling out the lateral cores, they can be demoulded smoothly. At this time, the side core-pulling mechanism needs to be set in the mold.
