    • PURPOSE: A foam injection molding method of an interior material for a vehicle, a foam injection molding mold, and a device for controlling reverse pressure of gas thereof are provided to improve molding efficiency such as insufficient molding or burr by smoothly filling resin through rapidly discharging gas after generating reverse pressure of the gas inside the mold for a few seconds. CONSTITUTION: A foam injection molding method of an interior material for a vehicle comprises: a step of inserting a product material through a hopper; a step of generating reverse pressure of gas inside a molten resin injection mold by injecting the gas inside the mold; a step of injecting the product material inside the mold through an injection machine; a step of shooting filled resin inside the mold by opening in a predetermined distance after injecting by removing the injection machine; and a step of smoothly filling the resin by discharging the gas inside the mold before completing the injection.
    • 目的:提供一种汽车用内饰材料的泡沫注塑成型方法,泡沫注塑成型用模具及其气体的反向压力控制装置,以通过快速放电使树脂平滑地填充而提高成型效率 在模具内产生气体反向压力几秒钟之后的气体。 构成:用于车辆的内部材料的泡沫注射成型方法包括:通过料斗插入产品材料的步骤; 通过将气体注入模具内而在熔融树脂注射模具内产生气体反向压力的步骤; 通过注射机将产品材料注入模具内的步骤; 通过移除注射机在注射之后以预定距离打开来在模具内注射填充树脂的步骤; 以及在完成注射之前通过在模具内排出气体来平滑地填充树脂的步骤。
