摘要： PROBLEM TO BE SOLVED: To provide an in-mold coating molding method capable of injecting coating in a mold in proper timing fitted to the coating and curing of a resin molded product and bringing about no problem in the curing time of the coating. SOLUTION: The mold for in-mold coating molding is equipped with a coating injection machine for applying coating to the surface of the resin molded product molded in a mold cavity and has the temperature sensor attached to the surface of the mold cavity on the arranging side of the coating injection machine. When the coating is injected in the space between the resin molded product and the mold cavity by the coating injection machine using the mold, the temperature of the injected coating is measured by the temperature sensor to detect the highest temperature in the temperature rise of the coating after the injection of the coating is completed as a peak temperature and it is judged whether the time until reaching the peak temperature after the injection of the coating is completed is within a range of 2-5 sec. In a case that this time is out of the range, the injection start timing of the coating is controlled so that the time until reaching the peak temperature after the injection of the coating is completed enters the range of 2-5 sec at the time of next in-mold coating molding.
