Abstract

PURPOSE:To eliminate necessity of molding box and improve workability by placing the body of a press die having a pipe hole on a reference model making a space corresponding to the thickness of crust and injecting a crust material in the space. CONSTITUTION:The body B of a press die provided with a crust material pouring port 14 and an air vent 15 is formed by pouring a core material 9 into a metal frame 4 on the reference model 1 and burying pipes 8, 13. Then, after separating solidified core material 9 from the model 1, a spacer 10 and a sealing material 16 which is mutually soluble with the crust material 11 are placed on the model 1. The body B is placed again on the model 1 and a crust layer is formed by pouring a crust material 11 from the crust material pouring port 14. Thus, a press die in which resin is used is obtained at high workability.
