MANUFACTURING METHOD OF MOLD, MOLD DIVIDING BODY AND THE MOLD

摘要

PURPOSE: A mold, a mold split body, and a method for manufacturing a mold are provided to improve the quality of a product by preventing a thermal medium leak. CONSTITUTION: A method for manufacturing a mold is as follows. Multiple mold split bodies(81A,81B,81C) are laminated. A convex part of a movable mold is formed by integrating the laminated mold split bodies. Protrusions(87,88) are formed on each joining surface(85) along the edge of a groove(82) and the outer edge of the joining surface. The outer edge of the joining surface and the edge of the groove are securely coupled. The edge of the groove forms a thermal medium passage.
