Abstract
Official abstract text for this publication.
In a mold mounting platen for an injection molding machine, at least one of a mold mounting member and a clamping force transmission member constituting the mold mounting platen has a central bearing surface in a central portion thereof and a peripheral bearing surface outside the central bearing surface. The amount of protrusion of the central bearing surface is larger than that of the peripheral bearing surface.
First claim
Opening claim text (preview).
The invention claimed is: 1. A mold mounting platen for an injection molding machine, the mold mounting platen comprising: a mold mounting member; and a clamping force transmission member; wherein at least one of the mold mounting member and the clamping force transmission member comprises: a central bearing surface in a central portion of said at least one of the mold mounting member and the clamping force transmission member; a peripheral bearing surface surrounding the central bearing surface; and a recessed portion provided between the central bearing surface and the peripheral bearing surface, and an amount of protrusion of the central bearing surface in a direction opposite to a direction of depth of the recessed portion and parallel to a mold opening/closing direction is larger than that of the peripheral bearing surface. 2. The mold mounting platen according to claim 1 , wherein the central bearing surface, the peripheral bearing surface and the recessed portion are provided on the mold mounting member, the clamping force transmission member has a surface facing the peripheral bearing surface, and a difference between the amount of protrusion of the central bearing surface and that of the peripheral bearing surface is larger than an amount by which the clamping force transmission member is deformed in the mold opening/closing direction at the surface facing the peripheral bearing surface at time of generation of rated clamping force.
