Abstract
The case assembly for a ceramic tile die includes a die cavity assembly formed by an insert support member and a plurality of inserts mounted on the upper surfaces of the insert support member. The inserts are preferably formed of tungsten carbide and may be universally mounted on the insert support member to provide a plurality of usable wear surfaces. A rigid frame surrounds the die cavity assembly, and mounting means are provided to permit limited, pressure induced movement between the die cavity assembly and the rigid frame. This minimizes the tensile stress to which the walls of the die cavity assembly are subjected.
Claims20
A case assembly for defining at least one die cavity for receiving material to be compacted by at least one press member which moves into said die cavity during a pressure cycle and being operative to minimize the tensile stress to which the walls of said die cavity are subjected by said press member comprising a die cavity assembly formed to define the peripheral walls of said die cavity, a substantially rigid frame means surrounding said die cavity assembly, and mounting means to mount said die cavity assembly within said frame means to substantially preclude movement thereof relative to said frame means in the direction of movement of said press member into the die cavity while permitting limited pressure induced movement of said die cavity assembly relative to said frame means in directions normal to the direction of movement of said press member into the die cavity.
An insert for attachment to an insert support in the case assembly of a ceramic tile die to form a wall section of the die cavity comprising an elongated unitary body having top and bottom walls, sidewalls joining said top and bottom walls and mounting means formed in the bottom wall of said body to facilitate attachment of said insert to the insert support.
