Zero-degree draft injection mold
By setting up linkage components and ejector pin structures, the problem of plastic products being difficult to smoothly eject from the cavity mold in existing zero-degree draft molds has been solved, achieving stable zero-degree draft of plastic products and ensuring reliable removal by the injection molding machine robot.

AI Technical Summary
Existing zero-degree draft injection molds cannot ensure that plastic products can be smoothly ejected from the cavity mold, especially for thicker plastic products. In the current technology, the plastic product is still embedded in the mother mold, and zero-degree draft cannot be achieved.
By setting the first and second linkage components, the moving template drives the sliding plate and the ejector plate to slide, so that the punch is first pulled out from the plastic product. After the plastic product cools and shrinks, it is separated from the sliding plate by the ejector pin and then ejected by the ejector pin, ensuring that the plastic product is stably and reliably pulled out from the cavity.
It achieves stable and reliable zero-degree draft of plastic products, ensuring that the injection molding machine robot can directly remove the plastic products, avoiding the problem of plastic products being difficult to remove after cooling and shrinking in the mold.
