    摘要: An injection-molding die including: a fixed die; a movable die; a cavity defined by the fixed die and the movable die; and a gate for injecting a melt resin into the cavity. The cavity includes: a flow-dividing structure that divides a flow of the melt resin injected into the cavity into a plurality of resin flows; and a flow-advancing area in which the resin flows generated by the flow-dividing structure are merged together. The flow-advancing area is formed thicker than a flow-hesitating area of the flow-advancing area in the cavity.

    摘要: After introducing gas into a cavity of a clamped die to boost a pressure therein, a resin material containing a foaming agent is injected. After forming a skin layer, at the same time as a start of a core-back operation for foaming the resin material or after the core-back operation, gas in the cavity is vacuum-suctioned to make a pressure in the cavity less than the atmospheric pressure. By cooling and solidifying, an injection foam molded article is obtained. Before complete solidification, gas between the resin material and an inner surface of the die is reliably discharged out of the cavity, so that surface recesses and generation of swirl marks due to gas accumulation can be prevented.
