Abstract:
A latching device (20) to facilitate removal or installation of replaceable cavity and core inserts in an injection mold assembly (10), characterized in that the latching device (20) comprises a latch arm 22 having opposed hooks 40,42 at one end and a pivot hole 44 at the other end, the pivot hole 44 of the latch arm 22 mounting on a center hub 24 that is rotatably attached to one side (12) of the mold assembly by means of an axial bore (56), the center hub 24 being configured so that the axial bore (56) is offset slightly with respect to the axis of a cylindrical bearing surface (46) that is received in the pivot hole 44 of the latch arm 22, such that this offset creates a camming action in the latching device 20 when the center hub 24 is rotated relative to the latch arm 22.
