する伝達ピンとを備えてなる射出成形金型。 In a device in which a molding cavity is formed by a fixed mold, a movable mold, and an ejector block having a recess for forming a protrusion on a molded product, an ejector pin fixed to an ejector plate and ejecting the molded product; A limiter that sets the moving distance of the block in the direction of ejecting the molded product to be smaller than the ejector stroke of the ejector pin, and a friction connecting portion with one end fixed to either the ejector plate or the ejector block and provided on the other. A transmission pin that moves the ejector block and the ejector plate synchronously until the end is inserted and the limiter applies the brake, and after the brake is applied, the synchronous movement is canceled by disconnecting the friction coupling part. Equipped with injection mold.
