ABSTRACT:
An in-mold foam molding equipment, includes at least a movable partition member for dividing a molding space formed by a pair of molds into divided spaces,wherein the partition member is composed of a plurality of divisional partition members,wherein each of the divisional partition members individually has a retreat positioning protrusion and a insert positioning protrusion, and the divisional partition members are installed in a slider, wherein the slider is configured to move between the retreat positioning protrusions and the insert positioning protrusions, and the divisional partition members are configured to be movable in cooperation with the motion of the slider moving by contacting with the retreat positioning protrusions or the insert positioning protrusions, so that the divisional partition members divide the molding space into divided spaces, and therefore an integral molded article suppressed in occurrence of large protrusions and deep holes can be manufactured.
