Ejector pin and injection mold with the ejector pin

摘要

An ejector pin includes a pin shaft and a pinhead locating on one end of the pin shaft. The pin shaft and the pinhead are eccentric and have different axle centers. The caliber of the pinhead is bigger than that of the pin shaft. An injection mold with the ejector pin includes a pushing board which forms at least one head-receiving cavity and one shaft hole extending from the head-receiving cavity to receive the ejector pin. The head-receiving cavity and the shaft hole are eccentrically arranged. When the injection mold is opened, the ejector pin stretches into a mold housing formed between a female core and a male core of the injection mold and pushed a product out of the mold housing. The ejector pin is fixed in the pushing board to avoid rotating of the ejector pin when pushing the product out of the mold housing.
