By repeating this process alternately, it is possible to continuously produce plastic molded products with beautiful patterns. In other words, when at least one molding mold is used to perform the second process, that is, molding and transfer painting of a plastic molded product, at least one other molding mold is used to perform the first process, that is, the molding process. performing a step of providing at least a pattern layer on the inner surface;
Each process is repeated in sequence. In order to do this, for example, two molding receiving molds 2 can be installed back to back and reversible (see Figure 1), or in addition to the above method, two molding receiving molds 2 can be installed. Various methods are conceivable, such as a method in which the molding receiving mold 2 is installed on a disk and made reversible (see FIG. 2), or a method in which the molding receiving mold 2 is installed on a disk and made rotatable (see FIG. 3).

First, in the method according to the present invention, a plurality of molding molds are used, and the step of providing a pattern layer on the inner surface of the molding molding and the step of molding and transfer painting of a plastic molded product are simultaneously performed. Because the process is repeated in sequence and alternately, a pattern layer is already provided on the inner surface of the mold when molding and transfer painting the plastic molded product, and therefore productivity is particularly high. It is something that Furthermore, since the pattern layer is uniformly provided on the inner surface of the mold using an elastic material, it can be applied to plastic molded products having complex three-dimensional curved surfaces. The surface pattern of the plastic molded product is beautiful without any cracks or wrinkles. Therefore, the continuous manufacturing method of painted plastic molded products according to the present invention has extremely high industrial utility value.
