PROBLEM TO BE SOLVED: To provide a mold assembly capable of controlling the temperature of the molten thermoplastic resin injected in a cavity easily, accurately, certainly and safely and capable of suppressing the quenching of the molten thermoplastic resin injected in the cavity. SOLUTION: The mold assembly is equipped with a mold, a core assembly 20 having a core 30 and first and second electrodes 60A and 60B. The core 30 is constituted of a core body 31 comprising an insulating ceramics material with a heat conductivity of 1.3-6.3 (W/m×K) and a thickness of 0.5-5 mm and the heat generation layer 32 electrically connected to the first and second electrodes 60A and 60B and formed at least on the top surface of the core body 31 to generate Joule heat. The core assembly further has a core attaching block 41. COPYRIGHT: (C)2008,JPO&INPIT
