ROTARY TYPE INJECTION MOLDING MACHINE

PROBLEM TO BE SOLVED: To provide a rotary type injection molding machine capable of rapidly adjusting the temperature of a mold to a desired temperature. SOLUTION: The rotary type injection molding machine 1 includes a rotary body 2, a support 3 for supporting the rotary body 2 rotatable and a temperature regulating liquid path. The temperature regulating liquid path includes: rotary body side liquid paths 2e, 2f provided in the rotary body 2 and having opening parts 2e1, 2e2, 2f1, 2f2; and primary liquid paths 3b, 3c and a secondary liquid paths 3d, 3e provided in the support 3 and having opening parts 3b1-3e1. The opening parts 3b1, 3c1, 3d1, 3e1 are positioned on the circumference on which the opening parts 2e1, 2e2, 2f1, 2f2 of the rotary body side liquid paths 2e, 2f are rotated. Circular arc grooves 3f-3i which extends circular arc-like by a prescribed length on the circumference and to which the opening parts 3b1-3e1 are opened are formed on the support 3 and the rotary body side liquid paths 2e, 2f are rotated with the rotation of the rotary body 2 through the circular arc grooves 3f-3i while communicating with the primary liquid paths 3b, 3c and the secondary liquid paths 3d, 3e.
