ドコート装置。 After a primary molded product is formed in a primary space of a combination mold made up of a plurality of molds that are matched with each other, one mold is separated from the primary molded product by opening the combination mold by a predetermined amount. A thermosetting paint is injected from the tip of an injector into a secondary space formed between the primary molded product held in the other mold to form a coating film on one side of the primary molded product. In the in-mold coating apparatus, a paint passage is formed in the injector and communicates with the tip, and the paint passage is slidably provided inside the injector so that the paint passage can be opened and closed with respect to the secondary space. an air passage opening/closing pin that is slidably formed inside the shuttle pin and can open and close the air passage in the shuttle pin with respect to the secondary space; an air supply means for supplying air, an air suction means for sucking air in the secondary space through the air passage before injecting the thermosetting paint into the secondary space, and cooling the shutter-off pin. An in-mold coating device comprising an air control means for controlling the air passage opening/closing pin in a direction to close the secondary space so that air circulates within the air passage.
