Claims

[Scope of utility model registration request]

A movable plate with a mold attached is movably attached to multiple tie bars connecting a fixed plate with a mold attached and a mold clamping support plate, and the movable plate is moved back and forth with respect to the fixed plate by a mold clamping device. In a molding machine that opens, closes, and closes the mold by moving the mold forward, a mold clamping force detector is attached to each tie bar, and the detector detects the mold clamping force during low-pressure mold clamping and during material filling after high-pressure mold clamping. The force is detected, and the difference between this detected value and the standard mold clamping force for each tie bar during normal low-pressure mold clamping and during filling an appropriate amount of material after high-pressure mold clamping is determined, and if this deviation exceeds the allowable value. A mold protection device characterized by being equipped with an abnormality detection device that outputs an abnormality detection signal at a certain point in time.
