成型品が汚れるという問題があった。However, after the release agent is attached to the squeeze pin, the squeeze pin is once retracted to the original position to perform casting, and when the squeeze pin is operated, the outer periphery of the squeeze pin is moved. If the release agent that has adhered to the mold is not squeezed by the guide holes and the squeeze pin projects into the thick wall of the cast product in this state, galling will occur between the squeeze pin and the molded product, and the squeeze pin will move. Was unstable in terms of speed and pressure. Further, if this staking is repeated, the life of the squeeze pin is shortened, and the machine must be stopped in order to replace the squeeze pin, resulting in a decrease in the operating rate of the machine. Furthermore, since the surplus lubricant remaining in the mold remains in the mold,
There was a problem that the molded product became dirty.
