ABSTRACT:
A mold assembly for casting or molding a multiple portion article in sequential shots without opening the mold assembly. The mold assembly includes a movable mold insert that permits the portions to be interconnected as an integral part of the casting process. The mold insert includes a first or male void for defining a male end and a second or female void for defining a female end. In operation, the mold insert is placed in a first position and molten material is introduced into a first cavity portion to form a first portion with a male end. The mold insert is then placed in a second position with the female portion surrounding the male end of the first portion. Molten material is introduced into a second cavity portion to form a second portion with a female end at least partially surrounding the male end of the first portion.
