Embodiment Construction

[0021] The invention will now be described in further detail with reference to the accompanying drawings, and in particular with reference to FIGS. , the rod element 12 has a suitable length to extend into the interior of the injection mold located in the injection molding machine. Such as Figure 5 As best shown, a rod element 12 is arranged to be connected to a movable core element generally indicated at 14 . The elongated rod member 12 has a first end 16 provided with a T-shaped projection, generally designated 18, configured to be inserted into a complementary T-shaped recess, generally designated 20, and protruding Also sized for such insertion and removal, the recess is formed in one end 22 of the movable core element 14. The rod element 12 is rotated so that the T-shaped protrusion is aligned with the opening 24 of the T-shaped groove 20 in the end 22 of the movable core element 14 . This is the unlocked operating position, allowing the actuating rod to engage and dis...

Abstract

A releasable actuator rod assembly for a moving core element in an injection mold tool in an injection molding machine has an axially elongated rod member of suitable length for extending into the injection mold tool in the injection molding machine. A T-shaped projection on one end of the rod member is received in a T-shaped slot on the moving core element. The rod member is rotatable between a locked position to engage the first end of the rod member with the moving core element and a second unlocked position to disengage the rod member from the moving core element. A pre-load detent housing retains the second end of the rod member to the actuating plate to restrain the rod member from rotating during operation to prevent disengagement between the rod member and the moving core element.

Description

technical field [0001] The present invention relates generally to injection molding and, more particularly, to a releasable actuating rod assembly for a movable core element in an injection mold. Background technique [0002] Various methods are known for installing movable core elements in molds in injection molding machines. These installation methods involve installing a long single core element piece that extends rearwardly beyond the core element to position and mount the anchor block to the actuator plate, which is typically the ejector plate of the injection mold. Another known method of installing a movable core element in a mold is a two-part solution in which an intermediate rod or rod is connected in a flexible manner to the back or back of the core element and its opposite end is positioned and attached to the An anchor block or other suitable component on an actuating plate, usually the ejector plate of an injection mold. These installation methods are general...
