Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a die for processing ejector pins. Background Technology

[0002] Injection molds are tools used to produce plastic products, while ejector pins are precision components in injection molds used to eject plastic products. They are usually used in conjunction with ejector sleeves to ensure that products are successfully demolded without deformation or damage.

[0003] Existing ejector pin processing molds are prone to rapid temperature rise after prolonged use. As the temperature rises, the lubricating oil applied between the ejector pin and the ejector pin evaporates, so it is necessary to replenish the lubricating oil regularly. However, most existing ejector pins are disassembled and assembled individually, which makes the operation cumbersome. Therefore, this utility model provides an ejector pin processing mold.
