Metal mold for manufacturing a slider for a slide fastener

A metal mold for molding a slider of a slide fastener by die casting to integrally produce a pair of oppositely disposed upper and lower wings and a lug of which only one end is secured to an upper surface of said upper wing, wherein the metal mold comprises:

• an upper mold having a cavity for integrally molding an upper surface and lateral side surfaces of the lug, except rear lateral legs of the lug, as well as part of the upper surface of the upper wing;
• a lower mold having a cavity for molding part of said lower wing to define a profile of a lower surface of the lower wing, wherein said upper and lower molds are capable of moving up and down relative to each other in order to close and open the metal mold in an alternative manner;
• and
• at least two sliding molds each having a profile capable of molding the remaining portions of said upper and lower wings and of said lug not molded by the upper and lower molds,
• wherein a cavity formed when the upper and lower molds are in tight contact with each other has such a cross section such that the at least two sliding molds are capable of being removably introduced into the upper and lower molds from their front and rear sides.
