SOLUTION: The manufacturing method for the mold for the lost wax precision casting is constituted as follows. A two-liquid reaction hardening type urethane resin liquid F, which is composed of a polyfunctional polyol component A, a polyfunctional polyisocyanate component B, a plasticizer C, a wax component D, and a hollow resin balloon E, is hardened. Thus, the resin pattern is formed. A primary layer composed of a plurality of refractory coating layers, in which an epoxy silicone layer is interposed in-between, and a back-up layer, which is composed of a plurality of thick film coating layers, are coated on the surface of the resin pattern. Preheating is performed to it for 2-8 hours in the low temperature range of 60-120 °C. 5-50 % by weight of the resin pattern is initially dewaxed. And, the temperature in the furnace is gradually increased. Heating is executed for 2-5 hours in the intermediate temperature range of 150-500 °C. Calcining is performed for 2-5 hours in the high temperature range of 500-1,000 °C. As a result, the mold is formed.

摘要： PROBLEM TO BE SOLVED: To solve the problems of a conventional wax pattern and to provide a resin pattern having good losing characteristics and high forming precision. SOLUTION: In precision casting with a lost wax method, the resin pattern is used instead of the wax pattern. This resin pattern is formed by hardening reaction hardening resin liquid (B) containing 10 to 40 wt.% liquid plasticizer (A) within 5 min pot life at a room temperature. Further, the hardness at 80°C is in a range of 30 to 60 Shore D hardness. COPYRIGHT: (C)2003,JPO
