形金型。 The product space defined by the fixed mold and the movable mold is filled with molten resin, and the mold is clamped after or in parallel with resin filling to pressurize the molten resin, thereby forming holes parallel to the mold clamping direction. In a mold for molding a molded product having a mold, one of the fixed mold and the movable mold has a molding surface corresponding to the hole,
In addition, a boss portion that is longer than the wall thickness of the molded product is formed protrudingly, and the other mold is provided with a slide core that faces the boss portion, and when the mold is opened, the tip of the slide core touches the molding of the other mold. A resin molding mold that is located on the same plane as the product, and is biased by an elastic body so that it comes into contact with the boss portion and sinks into the other mold just before mold clamping is completed. .
