REACTIVE INJECTION MOLDING DIE

摘要

PROBLEM TO BE SOLVED: To make it possible to shorten a time requiring for molding in one cycle and enhance a productivity by improving the temperature responsiveness in a mold relating to the temperature adjustment of the mold. SOLUTION: This mold consists of a male mold 1 and a female mold 2. The female mold 2 is composed of a surfacing layer 5 made of metal and a reinforcing layer 6 for reinforcing the surfacing layer 5. Piping 4 for circulating a heating medium therethrough is provided in the reinforcing layer 6 near the surfacing layer 5 and the piping 4 and the surfacing layer 5 and bonded together with soldering material. Thus, the temperature of the heating medium in the piping is rapidly conducted to the surfacing layer, thereby improving a temperature responsiveness.
