Abstract
The invention relates to the technical field of mold systems, in particular to a mold system for manufacturing a draw gear body intermediate core. The mold system comprises a lower mold assembly, an upper mold assembly, a core injection assembly and a core ejecting assembly. A first mud core groove is formed in the upper surface of the lower mold assembly. A second mud core groove is formed in the lower surface of the upper mold assembly. The lower mold assembly is provided with the upper mold assembly to form an assembled mold, and meanwhile the first mud core groove and the second mud core groove are matched to form a mud core cavity. The core injection assembly is arranged above the assembled mold. The core ejecting assembly is arranged on one side of the core injection assembly. The assembled mold is arranged below the core injection assembly for core injection, and then the assembled mold is moved to be arranged below the core ejecting assembly. A draw gear body intermediate core material is injected in the mud core cavity of the assembled mold through the core injection assembly, blowing hardening is carried out on the intermediate core in the mud core cavity through the core ejecting assembly, and pressure exerting and ejecting are implemented. According to the mold system, molding speed is high during production of the draw gear body intermediate core, a mud core is hard, the outline is clear, deformation is little, the surface quality is high, and core falling is precise. The quality of a produced draw gear body is greatly improved.
