Special Ejection - 14 Inch Length Plastic Extension Rod Mold

This set of Extension Rod Mold completes two-thirds of the action during the opening process, which greatly saves time. This set of molds has three design highlights: 1. Automatic unscrewing thread is achieved through linear gears. The thread core is ejected by using the mold opening force, without adding other drive mechanisms. 2. Calculation of the stroke of the pull rod and the rack. The ejector mechanism is pulled only after the thread core is completely withdrawn. There is a small delay calculation here. 3. Vertical ejector mechanism, the hydraulic cylinder drives the push plate to directly eject the product.

The mechanism of this extension rod mold is shown in the video. When the mold is opened, the rack fixed on the movable mold side drives the gear to rotate. Unscrew the threaded core and separate it from the product. According to the stroke, when the threaded core is completely separated from the product, the ejector mechanism is pulled out by the pull rod. The product is separated from the cavity. Then the hydraulic cylinder pulls the ejector plate to push out the product and make it fall.

Reduced cycle time: Efficient core pulling and ejection directly translates to faster mold cycles and higher production.

Gentle, consistent part demolding: Minimizes stress on the precision plastic extension rods during ejection, virtually eliminating the marking, deformation or "sticking" problems common in standard molds.

Reduced scrap rate: Consistent, reliable ejection significantly reduces part damage and scrap, maximizing the yield of usable plastic extension rods.

Precise dimensional control: Each cavity in this extension rod mold is machined to exacting tolerances, ensuring that each batch of plastic extension rods produced meets precise dimensional specifications.

Built for durability and long life: Made of high-quality hardened tool steel, the mold is ruggedly constructed to withstand the rigors of high-volume extension rod production, ensuring long-term durability and minimizing downtime.

Superior surface finish and detail: Advanced machining and polishing techniques ensure that the mold cavity produces plastic extension rods with excellent surface quality.

Efficient design: Optimized cooling way layout and efficient runner design help shorten the manufacturing cycle of extension rods and maintain stable product quality.
