Because the cover body of the automobile instrument cover is of a thin strip-shaped structure, especially the fixing strip is small in thickness and large in length, the problem that the injection pressure is insufficient during injection molding, and molten slurry is not easy to enter the forming seam of the fixing strip possibly exists, so that the forming quality is poor. Aiming at the problems, the die mainly makes three improvements:
1. the multi-point feeding type slurry feeding device is provided with a plurality of discharging pipes, so that slurry can efficiently and smoothly enter the cavity, and the molding efficiency and the molding quality of the mold are improved.
2. Temperature adjusting pipelines are arranged on two sides of the casting core body, so that the casting assembly is provided with a higher temperature, the fluidity of slurry is maintained, the slurry can enter a small gap of a cavity more easily, and the molding efficiency and the molding quality of the mold can be improved.
3. The arrangement of the pushing oil cylinder enables the discharging pipe to form a needle cylinder type structure, greatly improves injection molding pressure, compensates for the problem of insufficient pressure of an injection molding machine, and improves the molding efficiency and molding quality of the mold.
