ABSTRACT:
An in-mold coat-forming mold and an in-mold coat-forming method are provided, wherein the mold prevents leakage of a coating material for the long term, which is likely to occur when the in-mold coat-forming method is carried out. By disposing a grove, a pressure piece, or both of them so as to serve as coating-material leakage-preventing means, in the vicinity of the edge of a mold cavity adjacent to a shear-structured engaging portion disposed along the circumference of the mold cavity, a coating material is prevented from leaking out of the mold from the engaging portion, and problems such as an adverse affect on a formed product caused by the leaked coating-material and a damage on the mold are prevented, whereby in-mold coat-forming is stably performed for the long term.
