    摘要： By managing a coating material injection time and the like parameters so that they may be controlled within specifically determined ranges, an in-mold coating formation method is provided for manufacturing a molded product coated with a coating layer having a uniform quality in its outside appearance. By continuously and unifyingly managing a mold opening amount and a mold closing force, an in-mold coating formation method and an in-mold coating formation apparatus are provided which are so formed that, if the control of a mold closing force and the control of a mold opening amount are continuously changed and at the same time a high precision and a high response are maintained, it is possible to enlarge a selectable range for selecting a molding condition, thereby producing an integrally formed molded product having an excellent outside appearance and whose coating layer has a high adhesion strength. Further, there are provided a mold having a specifically formed auxiliary cavity and an in-mold coating formation method which employs said mold, so that it is possible to prevent a coating material from leaking out of the mold, thereby shortening the molding formation cycle, and making it possible to manufacture a molded product having a stabilized quality. Moreover, by controlling an internal pressure in the mold cavity under a predetermined condition after the injection of the coating material, there is provided a further in-mold coating formation method which makes it possible to obtain an integrally formed molded product whose coating layer has a sufficient strength with the molded product, without having to use a special coating material and a special resin to be used for molding. In addition, by using a mold having a specifically shaped sub-cavity, there is provided a still further in-mold coating formation method which can keep mold temperature at a relatively low value, cause the coating material to cure at a predetermined temperature and within a predetermined time period, thereby shortening the molding formation cycle, improving the productivity, improving the physical properties of a coating layer, thus obtaining a good molded product.

    摘要： 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.

    摘要： An in-mold coating method for molding a molded product with an excellent external appearance. A resin molded product is kept pressed against a mold cavity surface until immediately before coating. Mold-clamping force in a second step in which the shape of the resin molded product is fixed and that in a fourth step are selected so that the deformation of the mold cavity by the mold-clamping forces is substantially the same in the second and fourth steps. Even if the mold cavity deforms by the mold-clamping force in the second step, the mold cavity deforms similarly in the fourth step to provide a uniform coating thickness. Alternatively, a mold-clamping force smaller than that in the first step is selected for the second step to reduce the degree of deformation of the mold cavity and to achieve a uniform coating thickness.
