Abstract
An injection molding machine is illustrated with tie bars extending from a stationary die plate. A movable die plate is slidably movable along the tie bars. Corrugated elastic sleeves cover the tie bars and are seated at opposite ends on the die plates to keep molded parts from contacting the tie bars when the mold is open and thereby protect the molded parts from contamination by lubricant on the tie bars. In the embodiment shown, the corrugated sleeve is made of plastic material and is split longitudinally to facilitate assembly. The split sleeve construction enables the sleeves to be assembled sidewise onto the tie bars, and held snugly onto the bars by wires or cable ties.
