ABSTRACT:
The cope flask and drag platen of a matchplate molding machine are supported for up and down movement on vertical guide rails by sliding bearings or slippers located adjacent to corners of the flask and the platen. Each slipper includes a mounting block and a separate bearing pad connected to the mounting block by screws which may be independently adjusted to establish uniform face-to-face contact between the bearing pad and the rail. The screws also may be quickly released to enable removal and replacement of the bearing pad without disturbing the position of the mounting block.
