[0002] Automotive interior parts are generally manufactured using the injection molding process. Injection molds are tools used to produce plastic products and give them a complete structure and precise dimensions. Specifically, the heated and melted plastic is injected into the mold cavity under high pressure by an injection molding machine. After cooling and solidification, a molded product is obtained.
[0003] A search of publication number CN215359637U discloses a high-quality, high-gloss, seamless injection mold for automotive interior parts, comprising a mold base, a lower mold, an upper mold, and a pouring gate. The upper surface of the mold base is provided with a mounting groove, in which an electromagnetic stirrer is provided, a lower mold is provided above the electromagnetic stirrer, and an upper mold is provided above the lower mold. The closed interior of the lower mold and the upper mold is a mold forming cavity, a pouring gate is provided on the top of the upper mold, a liquid injection hole is provided on the pouring gate, and an exhaust device is also provided on one side of the pouring gate.
