The invention discloses an ejector sleeve ejection mechanism which comprises a lower fixing plate, an ejection rod, an ejection block, a first pressing block, a second pressing block, a third pressing block, an ejector sleeve and an equal-height screw; the ejector sleeve is arranged on one side of the third pressing block; the ejector sleeve comprises a sleeve; one end of the sleeve is contacted with the first pressing block, and the other end of the sleeve is pressed against a cylindrical hole of a product; an ejector sleeve pin is arranged in the sleeve; one end, arranged in the second pressing block, of the ejector sleeve pin is contacted with the third pressing block; one end of the equal-height screw is arranged in a male molding plate, and the other end of the equal-height screw is arranged in the second pressing block. According to the ejector sleeve ejection mechanism, the first pressing block, the second pressing block and the third pressing block are arranged, the sleeve is fixed on one ejection plate, the ejector sleeve pin is arranged in the second pressing block, and when a mold is opened, an upper ejection plate and a lower ejection plate move to the product direction, the sleeve moves to the product direction, and the product is smoothly ejected out; and with the ejector sleeve ejection mechanism, the ejector sleeve is arranged on one side of an ejection rod hole, so that the product is smoothly demolded.
Description
【Technical field】 [0001] The invention relates to a cylinder ejecting mechanism, in particular to a cylinder ejecting mechanism applied in a mold. 【Background technique】 [0002] A mold is a tool used to shape an article. This tool is composed of various parts. Different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. In the manufacturing process of plastic molds In many cases, it is necessary to set a column hole on the product. For this type of product, it is necessary to set a cylinder on the ejection mechanism of the mold. The cylinder is a kind of circular through hole or blind hole used on the product. And the rubber position must be ejected. It is an ejection accessory used. The sleeve is composed of a sleeve and a sleeve pin. Usually, the sleeve is mounted on the ejector plate, and the sleeve pin is mounted on the lower fixing plate. [0003] see fi...
