劣り、工程が多いという問題点があった。Some moldings, such as Zydozorotecta mold inders for automobiles, have identification parts such as letters, symbols, and patterns on their outer surfaces. A conventional method for manufacturing this type of molding is to form an identification part on the surface of the molding manufactured by extrusion molding using a real stamp, mark printing, etc., but if the surface is not flat, it cannot be processed. Therefore, there were problems in that there was no three-dimensional effect, the Ni+4 abrasion resistance was poor, and there were many steps.

題点がめった。Other manufacturing methods include forming convexes or four parts on the mold ink surface by injection molding, and then applying treatments such as pot stamping, coloring, mask painting, etc., but hot stamping has poor abrasion resistance. The process is long,
In the case of color contrast and mask painting, the problem of high cost often occurred.

いう問題点かあった。Furthermore, there is a method of forming the identification part by two-color injection molding, but the mold cost is high and a 41p cut is required, so there is a 4J point in the molding process. It has been considered to insert a printed film into an injection mold, but this poses a problem in that the film moves due to injection pressure and heat, making it impossible to form the identification portion in a predetermined position.

であればよい。This invention relates to a method of manufacturing a molding having an internal cavity by blow molding, in which an identification part is formed on the inner surface of a mold forming the outer surface of the molding. The identification part is characterized in that the parison is sandwiched between the mold and the mold, the parison is expanded by blowing compressed air into the parison, and the identification part is solidified integrally with the identification member. The manufacturing method for molding is as follows.
do. FIG. 1 is a perspective view showing a Zydozolotecta morte ink manufactured according to an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line A-A, and FIG. 4 is a vertical cross-section showing the manufacturing process. Figure 5 is a perspective view of the identification section A'46.
The figure shows an identification member 5 fixed to the four parts 4 formed on the outer surface of the vertical hollow molding body 2 without using the I'iu process. is formed. The identification part is a character in the embodiment, but it may also be a symbol, a pattern, etc. as long as it can be identified from other parts.

しない樹脂または金属製であってもよい。The manufacturing method is as shown in FIG. 6, with the mold open, the identification member 5 is brought into contact with the protrusion 7 of the cavity mold B, and the identification member 5 is suctioned from the suction tube 9 to be placed on the protrusion 7. 1. Identification member 5
As shown in Fig. 5, the identification part is formed of a resin that is compatible with the molding body 2, and is preferably made of a resin that is compatible with the molding body 2, and is made of a punched sheet member such as a synthetic resin film or a molded product. In some cases, it may be made of incompatible resin or metal.

にも１商川’ｕＪ能である。In the above explanation, it is not always necessary to form the convex part 7, but if it is formed to form the four parts 4 on the mold indder main body 2, the adhesion of the identification member 5 is improved as described above, and the identification part It is possible to give a three-dimensional effect to the IIT/! of the identification part. ? It is possible to improve the oxidation property. Further, the means for fixing the identification portion 5 to the mold surface may be other than suction. Furthermore, the present invention is applicable to H constructions of moldings other than protector mold inks for vehicles.
以上説明してきたように、この発明によれば、ブロー成
