The connecting protrusion 7241 of the molding insert 724 is embedded in the connecting groove 7231, thereby achieving the connection between the second molding block 723 and the molding insert 724. After molding, the base 8 forms a transverse hole at the position of the second molding block 723 and the molding insert 724, so that the second sliding parting assembly 72 can demold the transverse hole.

[0046] As shown in the figures, in some embodiments, steps 16 are provided on both sides of the first slider 713 and the second slider 722. Sliding grooves are provided on the movable platen 41 at positions corresponding to the first slider 713 and the second slider 722.
