In the injection molding process, the mold base is a crucial component of the mold, serving as the framework for the entire mold structure. It is composed of various steel plates and parts. However, many only have a partial understanding of its significance. Due to the significant differences in processing between the mold base and other parts of the mold, mold manufacturers typically opt to purchase mold bases from specialized mold base manufacturers. This allows both parties to leverage their respective production advantages, ultimately improving overall production quality and efficiency.
In simple terms, the mold base mainly consists of pre-forming devices, positioning devices, and ejection devices. A typical configuration includes the top plate, A plate (front mold), B plate (back mold), C plate (support plate), bottom plate, ejector pin plate, ejector pin base plate, as well as components such as guide pins and return pins.
The size of a plastic mold is primarily determined by the dimensions and structure of the plastic product. To ensure the strength of the mold, the structural design should be as compact as possible. Based on the product’s external dimensions (such as the projected area and height) and its structural features (such as side-parting sliders), the dimensions of the inserts can be determined, allowing for a rough estimation of the mold base size.
