Rotary ejection mechanism of injection mold

The rotary ejection mechanism comprises an ejection block head, an ejection round rod, a rotary control guide rail and a fixing seat, the top of the ejection round rod is fixedly connected with the ejection block head, the bottom of the ejection round rod is rotationally connected with the fixing seat, the middle of the ejection round rod is rotationally sleeved with the rotary control guide rail, and a sliding groove is formed in the side wall of the rotary control guide rail; the sliding groove is of a three-section structure, the middle is an inclined section, the two sections on the two sides are vertical sections, the side wall of the ejection round rod is fixedly connected with a first bearing through a first screw, and the first bearing is located in the sliding groove. According to the invention, the inverted buckle demolding of an injection product is realized in a mode of ejection and rotation of the ejection round rod, the inclined movement mode of a traditional inclined ejection mechanism is chang
