The height of the second insert 10 is adjusted through the threaded connection between the second screw 17 and the second adjusting nut 18, so that the gap between the lower surface of the second insert 10 and the upper surface of the product is zero. Since the end face of the second insert 10 facing the product is also provided with the skin groove 8 of the same model as that on the first insert 7, the skin groove 8 of the second insert 10 is matched with the first color skin on the product at this time. Then, the first movable mold 4 is injected into the first cavity 6. After the injection is completed, the second color sealant is formed around the product. The first movable mold 4 moves downward to be separated from the second fixed mold 9, and the second color injection molding process is completed.
[0061] The second movable mold 11 rotating to the lower side of the first insert 7 carries out the first color injection molding process of the next product, which is as follows: placing the next product needing first color injection molding into the product cavity 5 of the second movable mold 11, moving the second movable mold 11 upward to combine with the first fixed mold 3, at this time, the flange 14 protruding from the first fixed mold 3 is inserted into the second cavity 13 and matched with the second cavity 13, the height of the first insert 7 is adjusted by the thread between the first screw 15 and the first adjusting nut 16, so that the lower surface of the first insert 7 and the upper surface of the product have a zero gap, then the first insert 7 is injected, and after the injection is completed, the first color skin pattern is formed on the upper surface of the product; the second movable mold 11 moves downward to separate from the first fixed mold 3, and the first color injection molding process of the next product is completed. The above process is repeated.
[0062] In summary, the beneficial effects of the utility model are as follows:
[0063] (1) The lower end of the first insert 7 and the lower end of the second insert 10 are designed as the same type of skin groove 8, without changing the product shape, when the second color injection molding is carried out, the skin groove 8 at the lower end of the second insert 10 can coincide with the skin pattern formed on the upper surface of the product, and the skin pattern pressure injury and scalding defects are solved.
