PURPOSE:To manufacture a good quality molded body with no warpage by a method wherein molding is performed under the condition that the temperature of a fixed mold and that of a movable mold are set to be different from each other and heat insulating means is provided between both the molds. CONSTITUTION:Mold temperature controlling holes 7, 8 and 12 are provided in a fixed mold 1 and a movable mold 9. Further, parallel grooves 6 and 13 as heat insulating means are formed on the parting parts of the molds 1 and 9. Thus, temperature difference can be provided between the fixed mold 1 and the movable mold 9, resulting in allowing to mold a molded body with no warpage. |
