In the injection molding process, in order to improve production efficiency, the mold design often adopts a multi-cavity structure so that multiple products can be molded at the same time. However, this design also brings a challenge. Between the cavities of each product and the inlet area of ​​the pouring cup, a material head connecting multiple products will be formed. After the injection molded part is taken out of the mold, these material heads become redundant parts that need to be removed, and because of their different shapes, they are often difficult to handle.
