Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 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. 2. The fixed platen of an injection molding machine according to claim 1 , wherein the first leg extends in an opposite direction to the mold mounting surface and is secured to the base frame.
