<p>A cast iron die carrier member for the die closing unit of an injection molding machine having a machined die mounting face which is interrupted by a pattern of shallow face grooves on the surface of which the casting skin of higher resistance and lower elongation is retained, in order to stiffen the die carrier member against bending and distortion under an elevated die closing pressure. The die carrier member also has axially extended r vertically braced supporting flanges reinforcing the cantilever-type clamping connection between the member and the guide rails of the machine base to further stiffen the die carrier member against bending and to thereby reduce the long-term wear of the guide surfaces of the die closing unit.</p> |
