Abstract

PURPOSE:To mold resins or molding materials in a turnable and movable manner in relation to a base material and other molding material by a method in which a shield film is provided in place in the inside of molds inserted with a base material, a molten resin is injected into the molds for molding, and then the shield film is removed. CONSTITUTION:An upper mold 1 and a lower mold 2 between which a base material 1 is put are pressingly clamped and fixed. In this case, a shield film 10 is set between the upper mold 1 and the base material 3. Molten resin material is injected under high pressures into the cavities 11 and 12 of the upper and lower molds from two gate 1a, whereby the resin injected into the upper mold 1 is interrupted from the resin injected into the lower mold 2 by the shield film 10 so as to prevent the intermixture of both resins. After the resins are cooled, the shield film 10 is removed, and therefore, the first molding resin material G and the second molding resin material H can be molded separately without being integratedly combined and the second molding resin material H can turn around the hole 3c due to contraction.

Since the size of the major portion 3a of the base material 3 is slightly reduced due to the shrinkage of the resin, the resin molded members C and D can be made freely rotatable with respect to the base material 3. Furthermore, as shown in FIG. 3, if another resin wheel E is attached to the boss CD in FIG. 2 and engaged with the gear of the resin molded member σ, a gear mechanism can be obtained in a rush. Further, as shown in FIG. 4, the end MF1 of the plate/gun-shaped resin molded member F is fixed to the base material λ. By using the elasticity of resin,
It is also possible to obtain raw material.

In such a case, in order to form -n, the gap between the outer circumferential wall of the recess 13 provided by the lower mold ZK and the hole 3d of the base material 3 is It is necessary to provide a seed gap t. If this is not done, the lower mold 2 and the base material 3 will collide at this portion, resulting in scratches on the mold. However, if there is no shielding film 10, the resin injected from the gate la will flow into the above-mentioned gap t, forming the resin molded part so that it can rotate around the pin I with respect to the base material 3. Can not do it. Therefore, according to the present invention, by inserting the blocking 1 odor 10 into the mold together with the base material 3 as shown in the figure, it is possible to prevent the resin from flowing into the above-mentioned gap t. 8 figure 1
