A foamable thermoplastic resin material is filled into a casting cavity formed by clamping the other mold in which a convex part is formed in a predetermined shape, and the mold is formed. This invention relates to a molding die in which a bushing rod or an air blower is used to extrude the processed product when the mold is opened, and a mold release method related to its use. The convex processed surface to be formed is a mold that is slidably slidable in the mold clamping direction and is provided as a main member of one of the molds, and the processed surface is retractable with respect to the cavity. When opening the mold, the nest, which is used as a processed face piece, is slid and stored from one mold to extrude the processed product, and in the middle of this process, if the pulling force due to slide friction is uniform, one mold is moved to the other mold equally. This invention relates to a molding die that can only extrude a processed product with a uniform application surface that covers the entire processing surface, and a method of using the molding die for mold release.

The molded convex part of the machined surface of a movable mold or a fixed mold is used as a slidable machined facepiece, and a liner is provided in one mold, and a nested machined facepiece is provided in the other mold. It fits into the groove through the mold clamp, and during molding, it forms an integral continuous surface as the processing surface of the molding die, allowing foam molding with good molding, while also providing protection for the processed product taken out after molding. On the other hand, from the casting part of the processed product that sticks to the mold, the nest is slid concentrically into one mold and stored.
As a result, the molding is completed while maintaining the surface properties of the cast part of the workpiece, and it can be removed by a mold release method that extrudes the workpiece by applying even pressure to the workpiece surface of one mold relatively. This was achieved by taking technical measures to achieve this goal.
