While inserting 27a, the front end is returned until it abuts against the plate 17. Furthermore, the injection molding device is driven to move the mold body 2.
is brought into contact with the fixed mold body 40 (see FIG. 1). At this time, there is nothing in the primary mold formed by the first female piece body 42 and male piece body 5, and there is nothing inside the primary mold formed by the second female piece body 43 and male piece body 5. In the secondary mold, a red sub-bottom object 10 and a yellow sub-bottom object 11 are provided. In this state, the red synthetic resin material G1 and the yellow synthetic resin material G2 are fed into the primary mold in the same manner as described above, and at the same time, the injection molding device Is on the fixed mold body 40 side is injected into the secondary mold. Transfer the white synthetic resin material G3 from the nozzle to the material distribution hole 44. The blue synthetic resin material G4 is fed into the runner groove 4 through the injection nozzle on the side.
6. As a result, in the secondary mold, a secondary two-color molded product 12 having a shape in which the red-shaped bottom-shaped object 10 and the yellow-shaped bottom-shaped object 11 are wrapped in the white synthetic resin material G3, and the red-shaped bottom shaped object 11 are formed.
A secondary three-color molded product 13 in which the sub-bottom shaped product 10 and the yellow secondary molded product 11 are wrapped in a blue synthetic resin material G4, and a white runner 47 are molded. Next, drive the injection molding device S to separate the movable mold body 2 from the fixed mold body 40, and
The second protruding base 24 is activated by operating the hydraulic cylinder 25.

物が製造されることになる。By pushing out the second projecting base 24, the projecting pins 26 and 27 are pushed out from inside the male piece body 5, and the secondary two-color molded product 12. The secondary three-color molded product 13 is separated from the male mold piece 5 and dropped outside the injection molding apparatus (see FIG. 3). and,
The operation of the hydraulic cylinder 25 is released to return the second projecting base 24 to its original state, and the projecting pins 26 and 27 are returned to the male piece body 5. Next, as mentioned above, the injection molding apparatus S
The pressing shaft 50 of the first protruding base 22 degree rotation shaft 3. Push out the rotary transfer table 4 forward via the push-out pin 23 (see Fig. 2), and rotate the rotary transfer table 4 to transfer the primary molded product 10.11 molded into the primary mold into the secondary mold. Transport. In this way, multicolored molded products are continuously produced.
