Abstract
An injection molding mold including an insert in-part defining the mold cavity and readily accessible for replacement from the side of the mold. The insert has a molding head at the mold cavity, a shank extending into a socket in the mold, a mortice in the shank for receiving a retainer to hold the insert in place and, preferably, a camming surface on the end of the shank for dislodging the insert from the mold. The retainer will preferably be a sliding pin having a bifurcated keeper portion providing two tapered prongs engaging opposed slots on the insert's shank for holding the insert in place during molding and subsequently for camming the insert loose from the socket at replacement time.
