Abstract

A movable platen according to the present invention includes: a mold clamping platen 42 having a projecting portion 62 in a mold closing direction-side surface; a mold mounting platen 44 mounted to the projecting portion 62 of the mold clamping platen 42 ; and a guide mechanism 50 fixed to the mold clamping platen 42 and supporting the mold mounting platen 44 . Only the mold clamping platen 42 is fixed to the guide mechanism 50 , while the mold mounting platen 44 is not fixed but placed on platen surface support portions 52.

First claim

The invention claimed is:

1. A movable platen comprising:
a mold clamping platen having a projecting portion in a mold closing direction-side surface;
a mold mounting platen mounted to the projecting portion of the mold clamping platen and configured to project from side surfaces of the mold clamping platen; and
a guide mechanism fixed to the mold clamping platen and supporting the mold mounting platen, the guide mechanism comprising:
a pair of platen surface support portions,
a pair of leg portions constructed integrally with the pair of the platen surface support portions respectively,
a pair of linear motion guides held on the pair of the leg portions to prevent floating of the mold clamping platen, and
an adjustment mechanism configured to adjust the height of the mold mounting platen, the adjustment mechanism provided between the platen surface support portion of the guide mechanism and the mold on both sides of the mold mounting surface of the mold mounting platen,

wherein only the mold clamping platen is fixed to the guide mechanism by using fixing members, while the mold mounting platen is not fixed but placed on the pair of the platen surface support portions of the guide mechanism.

2. The movable platen according to claim 1 , wherein the mold clamping platen is constructed integrally with the guide mechanism supporting the mold mounting platen.

3. The movable platen according to claim 1 , wherein the mold clamping platen is constructed integrally with the guide mechanism supporting the mold mounting platen.
