The long nozzle of the injection molding machine is brought into contact with the passage 16.
The cylindrical body 1 is formed by filling the cavity with the injection material (see FIG. 2). In this case, no resin is supplied to the passage 25. Further, since the lower surface of the first stationary side insert 21 and the two surfaces of the movable side insert 15 are in close contact with each other at the annular portion, the resin does not enter into the central space formed by the two.

内に残って、可動側型板１４とともに移動する。Next, when the secondary molding is completed and the convex lens 2 is molded, the support block 2o is moved along the movable mounting plate I7,
After retracting, the movable mold plate I4 is moved to the movable mounting plate I together with the movable insert I5 by the drive rod I8 of the drive mechanism.
At this time, at the same time as the movable template 14 moves, the stripper plate I+ moves away from the fixed template 10 by a predetermined distance and follows the movable template 14.
The cylinder body I and the convex lens 2 which have already been molded are placed on the movable template I4.
The movable mold plate 14 moves together with the movable mold plate 14.

It is made to face the stationary side insert 22. Next, the movable template 14 is pressed toward the stripper plate II by the drive rod I8 of the drive mechanism. Next, the support block 20 is interposed between the movable mold plate 14 and the movable mounting plate I7, and the injection molding machine is inserted into the entrance portion 26a of the passage 26 through the through hole 29 of the fixed mounting plate 27. With the nozzle in contact with the above passage 26, the tertiary injection material is applied to the already formed cylinder! Then, the space formed by the convex lens 2 and the second stationary insert 22 is filled to form the concave lens 3 (see FIG. 4).

That is, first, each fixed side insert 2122 and each insert receiving plate 23.24 are opened, and with the solidified resin in the passage 25.26 attached to each insert receiving plate 2324 side, Pull apart side inserts 21 and 22. Next, when the stripper plate 11 and the movable mold plate 14 are opened, the product becomes attached to the movable mold plate 14. Then, the assimilated resin adhering to the insert receiving plates 23 and 24 is ejected by the runner ejecting pin and released from the mold, and the ejecting mechanism provided in the movable mold plate I4 is used to release the assimilated resin from the movable mold plate I4. To release the product smoothly.

好な製品を得ることができる。As described above, according to the method for molding a multi-colored molded product and the molding die of the present invention, the product surface of the movable mold is successively opposed to the product surface of a plurality of fixed-side mold bodies of the fixed mold. By injecting resin into the blue space formed by the product surface of the movable mold and the product surface of each stationary mold body, molded products such as compound lenses can be manufactured easily and inexpensively. Good quality products can be obtained.
