Abstract

PURPOSE:To provide metallic mold with which mold product of uniform density without defect can be molded reliably by detecting movement of movable body in order to close liner gate in response to feedback signals from the detector. CONSTITUTION:Molding substance is filled in mold cavities 1 through liner gates 2. As molding substance overflows, movable bodies 4 are moved outwardly against return springs 5. Reaction elements of the movable bodies 4 are detected by detectors 6 as the bodies 4 are moved outwardly, and electric signals from the detectors 6 are input to drive elements 7 which act accordingly to drive after control pins 3 so as to close liner gates 2. Immediately after the molded product is taken out of the metallic mold, this molding apparatus is restored to initial status.
