Abstract
A mold insert for an injection molding machine has a circumferential liquid conduit groove and a plurality of liquid-receiving bores extending inwardly from the groove. Baffles are removably inserted into the liquid-receiving bores and have heads located in locking engagement with the sidewalls, including the undercut portions thereof, to retain the baffles in their respective liquid-receiving bores. Each baffle has a blade that fits snugly within a liquid-receiving bore to separate the liquid-receiving bore into a liquid inlet passageway and a liquid outlet passageway. Fins project outwardly from opposite faces of the blade to create turbulence in liquid flowing into and out of the liquid-receiving bore, which enhances cooling (or heating) of the mold insert. The baffle is also useful with other solid components having a liquid conduit for cooling purposes and a transverse liquid-receiving bore intersecting the liquid conduit. An improved liquid barrier for use in preventing the flow of liquid in the liquid conduit groove is formed by a dam member substantially identical to the head of a baffle.
