Title: Cast-molding and cast molding die
Inventor: IIDA KEIICHI
IPC: B22F3/03
Filed: 1994-12-06
Abstract: PURPOSE: To perform cast-molding by using a non-water absorbing molding die at a region which requires complicated shaping or surface smoothness. CONSTITUTION: A complicated shape molding, especially a sharply profiled shape molding which is difficult to achieve a conventional cast-molding method can be easily performed without a flaw likely to occur at the time of die parting by using a molding die with a part of the molding face made of a polypropylene resin, vinyl chloride resin, polycarbonate resin, melamine resin, epoxy resin or acrylic resin. It is possible to manufacture a finished product with outstanding surface moothness directly and dispense with grinding work. Further, it is possible to allow only a molding die of a simple shape to become clogged of molding dies 2 by making the simple shape porous and the complicated shape non- liquid absorptive. Thus, the life of the molding die can be prolonged.
