PURPOSE:To enable simple and reliable processing of a thin molded member, by a method wherein cavity parts for gates are formed on both the right and left sides of a cavity part of a core and slide core, and bases of the cavity parts are communicated with the lower ends of sprues or runners. CONSTITUTION:Cavity parts 6a, 7b forming thin plates 2, 3 are formed on the front and back slide cores 6, 7 of the outside of a core 5 set up at the inside measurement of a thin molded member 1a. A cavity part 5a forming a back plate part 4 is formed between a top slide core 8 and the core 5, and cavity parts 9a, 10a for gates forming gate parts 11, 12 are formed on the tops of side slide cores 9, 10. In this instance, the titled mold is formed so that the gate parts 11, 12 are extended on both the right and left sides of the back plate part 4, and the cavity part 5a and the cavity parts 9a, 10a for the gates are communicated with each another. Bases of the cavity parts 9a, 10a for the gates are communicated with the lower ends of a sprues or runners 13 without interposing a cold slab well 14. A pressure loss, therefore, of a viscous fluid to be generated at that place is prevented and a molten material can be pressed in through a right and left gate parts at a time.
