[0002] At present, the electric vehicle market is increasing day by day. Among them, the electric vehicle taillight reflector bowl is one of the electric vehicle parts, and the demand is relatively large. The electric vehicle taillight reflector bowl is made of plastic material and is generally mass-produced by injection molds. During the injection molding process, it is difficult for the existing reflector bowl injection mold to simultaneously mold the buckle structure and the side connecting screw frame of the reflector bowl plastic part. After injection molding, secondary finishing and punching are still required. The overall quality and strength of the plastic part are relatively general, and the production efficiency of molding one plastic part at a time is also low. Therefore, it is urgent to design a one-mold double-out four-wheel electric vehicle taillight reflector bowl injection mold that can overcome the above defects.
