在汽车内外饰产品的生产过程中,由于外分型模具加工、配模过程存在误差,或型芯型腔配合出现误差,形成细小的台阶或产生飞边,影响到产品的外表面质量。文章通过研究内分型模具的结构,模拟分析模具运动过程,判断内分型模具是否在汽车内外饰产品上实现内分型,从而解决因外分型模具制造过程产生的误差引起的产品缺陷问题。 In the car interior and exterior products production process, due to the external sub-type mold processing, the mold with the error, or cavity with the error, the formation of small steps or flash, affecting the quality of the outer surface of the product. By studying the structure of the inner parting die, the article analyzes the movement process of the die, and judges whether the inner parting die can realize the inner parting on the inner part of the car, so as to solve the problem of product defects caused by the error caused by the manufacturing process of the outer parting die .
