Furthermore, one side of the upper surface of the upper molding cavity is provided with an injection molding hole.
Furthermore, injection molding holes are arranged on the left side edge and the right side edge of the upper surface of the upper molding cavity.
Furthermore, the front and back widths of the two sides of the upper molding cavity are enlarged towards the middle of the upper molding cavity.
Furthermore, the corners of the binding surfaces of the upper template and the lower template are provided with separating grooves.
Further, the upside of cope match-plate pattern is equipped with the hot runner plate that the block is connected, and the hole of moulding plastics is connected to the hot runner plate, and the edge on the binding face of hot runner plate and cope match-plate pattern is equipped with sled die cavity.
Furthermore, the injection molding hole is an inclined slotted hole.
Further, the front-rear width of the upper molding cavity side near the injection hole side: the upper molding cavity side distal from the injection hole side has a front-to-rear width of 61.7562: 61.8825.
Furthermore, positioning bulges are arranged on the binding surfaces of the upper template and the lower template.
Furthermore, the outer sides of the upper template and the lower template are provided with marks for marking the model of the mold.
The utility model has the advantages that: by relatively reducing the front and back width of the upper molding cavity side close to the injection molding hole side, the effects of consistent size of two ends and high precision after molding are achieved.
