Abstract

The invention discloses an inner stress reducing die. The die comprises an upper die base and a lower die base. A hydraulic rod and a piston rod used in cooperation are arranged between the upper die base and the lower die base. A connecting template is arranged below the upper die base. A die pouring gate is formed below the connecting template. A movable die is arranged below the die pouring gate. The lower die base is provided with a forming die used in cooperation with the movable die. The forming die is provided with a cavity, and the movable die is movably arranged in the cavity. According to the inner stress reducing die, the inner stress existing in an injection molding formed workpiece is eliminated, the quality of the injection molding formed workpiece is high, and the die production efficiency and yield are extremely improved.

Description

Technical field [0001] The invention relates to a mold injection process and a mold for reducing internal stress, and belongs to the technical field of molds and mold injection molding. Background technique [0002] Injection mold is a tool for producing plastic products, as well as a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to the high-pressure injection of heated plastic into the mold cavity by an injection molding machine, and the molded product is obtained after cooling and solidification. Injection molds are divided into thermosetting plastic molds and thermoplastic plastic molds according to the molding characteristics; according to the molding process, they are divided into transfer molds, blow molds, casting molds, thermoforming molds, hot press molds (compression molds), injection molds, etc. Among them, hot p...
