成されている。2. Description of the Related Art An automobile seat cushion pad is formed by injecting a polyurethane material into a cavity of a foaming mold and foaming the material. In the foaming mold, the gas generated during foaming, which does not contribute to the formation of the cushion pad, is discharged to the outside of the mold, so that there is no occurrence of molding defects such as formation of underfill or voids in the cushion pad. Thus, a large number of gas vent holes (vent holes) are formed.

れている。However, in the above foaming mold provided with a vent hole, unnecessary foaming gas is discharged at the time of foam molding, but an expanding polyurethane raw material leaks out of the mold through the vent hole. The polyurethane raw material that leaks out of the mold is solidified or hardened into a shape similar to the shape of a round bread, and is thus commonly called “bread”.

Also, if the “pan” leaks out of the mold and is left as it is, it will cause poor gas release and molding in the next cycle, so it will be necessary to remove it manually from the outside of the mold every cycle. Removing the objects took a lot of trouble and time.
