PROBLEM TO BE SOLVED: To provide an injection mold assembly not becoming large-sized in a mold structure, capable of simply changing the position of a runner in a case that the resin flowing in a cavity is deficient and capable of fully filling the cavity with the resin. SOLUTION: The injection mold assembly comprises an insertion member 5 having a runner 9 for allowing a resin to flow toward the cavity 11 of an arcuate shape part 3 and provided in a mold for manufacturing a molded product 1 having at least a partially arcuate shape. The member can be rotated freely and change the flow direction of the resin by changing the direction of the runner 9 by rotation. The assembly is further provided with a fixing mechanism capable of stopping the movement of the insertion member 5 in a rotary direction. COPYRIGHT: (C)2005,JPO&NCIPI
