Abstract

PURPOSE: To obtain a self-during or thermosetting mold of good releasing property at a low cost by using impact-resilient and heat-resistant members on the surface of a pattern and packing lightweight-, heat-insulating- and heat-resistant aggregate of a small coefficient of dielectric loss in the pattern.
CONSTITUTION: Clay 13 or the like is built up on a matrix pattern 12 and a packing material 2 composed of foamed gypsum or the like which is light in weight, is superior in heat-insulation and heat resistance characteristics, and has a small coefficient of dielectric loss is packed on this. Thence, rapping is done to obtain an upper die 10 or a lower die 15. Thence, silicone rubber 1 or the like of superior impact resilience and heat resistance is poured between the packing material 2 formed on the surface of the pattern by leaving a fixed thickness and a matrix 3, and the silicone rubber 1 or the like is impregnated and set in the front layer part of the packing material 2. Thereby, the pattern of lightness in weight and superior releasing property may be manufactured at a low cost.
