Patent number: 9475228Abstract: An adjustable platen assembly and method of assembly therefore. The platen assembly has a platen and a pressure plate attached to the platen. The pressure plate may be rotatable around a longitudinal axis of the rod according to the size of a mold half mounted to the platen. The platen assembly may have at least one platen support mounted to the platen. The at least one platen support may be rotatably mounted to the mold clamp. The at least one platen support can be rotated according to the size of a mold half mounted to the platen. The adjustable platen provides support to the mold half to reduce the amount of deformation to the mold half that is caused by the application of a closing force.Type: GrantFiled: September 17, 2014Date of Patent: October 25, 2016Assignee: Graham Engineering CorporationInventor: John M.

Patent number: 8814553Abstract: A modular mold clamp assembly for use in a molding machine. The assembly has a frame with a base member and oppositely-facing end members, with the oppositely-facing end members having mounting areas provided thereon. First and second platens are movably mounted on the base member between an open and a closed position. The platens are mounted on the frame and are movable relative to the frame without transmitting forces to the frame. The frame, containing the platens, can be mounted or unmounted to the molding machine by the use of mounting hardware cooperating with the mounting area of the frame.Type: GrantFiled: May 3, 2013Date of Patent: August 26, 2014Assignee: Graham Engineering CorporationInventors: John M. Mathy, Jr., Paul M. Oles, David N. Fiorani
