FIXED PLATEN OF INJECTION MOLDING MACHINE

摘要

A fixed platen of an injection molding machine is provided with a first leg protruding at a substantially central portion of a lower part and secured to a base frame and second legs protruding left and right. Each of the second legs is provided with a thin portion thinner than the fixed platen. Thus, a deformation difference between the upper and lower sides of the fixed platen caused during nozzle touch operation or when the fixed platen is subjected to a mold clamping force can be reduced.

1. A fixed platen of an injection molding machine, secured to a base frame and capable of supporting a fixed mold, the fixed platen comprising:
a mold mounting surface capable of being fitted with a mold; a tie-rod insertion part at a corner through which a tie rod is configured to be passed for fixation; a first leg protruding at a substantially central portion of a lower part and secured to the base frame; and
a second leg protruding near the tie-rod insertion part at the lower part and secured to the base frame, wherein the second leg comprises a thin portion thinner than the fixed platen along the axis of the tie rod and respective thickness-direction centers of the thin portion and the fixed platen are substantially coincident along the axis of the tie rod.
