PURPOSE:To contrive to improve the heat resistance, corrosion resistance, strength and the like of a block and to save its weight by a method wherein a thermoplastic resin such as polyphenylene sulfide (PPS) or the like is used and, on the other hand, a mold containing a plurality of slide molds is employed. CONSTITUTION:A cavity 42 to mold a mixture block is marked off by a stationary mold 16, a movable mold 18 and slide molds 20a-20d. A flow path in a gate part 40 located at the tip of a nozzle member 32 communicates to the cavity 42 in order to flow the molten resin fed to the nozzle member 32 into the cavity 42. The molten resin solidifies because of the lowering in temperature so as to shape a molded part corresponding to the form of the cavity 42 or the mixture block. After that, a movable part 14 is displaced it its initial mold opening position so as to part it from a stationary part 12. In this case, PPS or the like is employed as the thermoplastic resin excellent in heat resistance, dimensional stability and the like. |
