[0038] The slider body 1 is slidingly arranged in the inner cavity of the double-shot mold, is matched with the mold core in the inner cavity of the double-shot mold, and is matched with the mold core in the inner cavity of the double-shot mold.

[0039] First, the injection molding is performed on the single-shot mold, when the front mold of the single-shot mold is downwardly closed, the shovel base 4 in the single-shot mold is gradually inserted into the shovel base hole 3, the front side of the shovel base 4 pushes the front side of the shovel base hole 3 to move inwardly to form a sealing glue position and is closed, and the blocking pin groove 9 on the shovel base 4 avoids the blocking pin 8 in the slider body 1 and is inserted into position.

[0040] After the first injection mold is opened, the shovel base 4 in the first injection mold is pulled out upwardly from the shovel base hole 3, the rear side of the shovel base 4 in the first injection mold does not contact the blocking pin 8 and the rear side of the shovel base hole 3, the limiting groove 10 and the limiting component 11 are matched, the slider body 1 is prevented from moving, and the glue position plug 2 at the front end of the slider body 1 is retained in the product to continue sealing the glue position and keeping still.

[0041] After the first injection mold is completely opened, the first injection mold is rotated by 180 degrees around the center of the rotating disc of the two-color injection molding machine to the second injection position to perform the second injection.

[0042] When the front mold of the second injection mold is closed, the front side of the shovel base 4 of the second injection mold contacts the head of the blocking pin 8 and gradually compresses the blocking pin 8 into the spring hole 5, the shovel base 4 of the second injection mold continues to move downward until the shovel base 4 is completely inserted into the shovel base hole 3, at this time, the blocking pin 8 is ejected from the spring hole 5, the front side of the blocking pin 8 contacts the rear side of the shovel base 4 of the second injection mold, and the front side of the shovel base 4 of the second injection mold also completely contacts the front side of the shovel base hole 3, thereby keeping the closure of the glue position sealing of the slider body 1.

[0043] After the second injection mold is opened, the shovel base 4 of the second injection mold moves upwardly and is pulled out from the shovel base hole 3, the rear side of the shovel base 4 pushes the front side of the blocking pin 8 and drives the slider body 1 to retreat backward, the glue position part at the front end of the slider body 1 is completely pulled out from the product, the slider body 1 completes the action of retreating to the position, and thus the first injection and the second injection mold injection process are completely finished.
