The mold is used to form a spacer pit, and an asiter cut molded part is formed at the tip of the block mold, which becomes an undercut part of the molded product, so that the asiter cut molded part can protrude from the center edge of the fixed mold. , a guide hole that opens to the center cut molding part is provided in the block mold, a knockout screw is slidably inserted into the guide hole, and the undercut part of the knockout mold is inserted slightly from the center edge tee of the fixed mold. A stopper is provided to prevent further protrusion in the protruded state, and the amount of movement of the knockout pin is made larger than the amount of movement of the block mold.1. After opening the movable mold, push up the mold and press it.
When the foot-cut molding part is slightly protruded from the position of the fixed mold, the mold comes into contact with the stopper and is prevented from protruding any further, causing the molded product to rise slightly. The position can be fixed when it is taken out from the tee, and by pushing the knockout bit up from the aciter cut molding part in this state, the molded product can be freely elastically deformed and removed.
The advantage is that a molded product having an associating cut portion can be obtained with a relatively simple structure without employing a slide core or the like with a complicated structure as in the conventional method.
