Secondary synchronous limiting ejection structure of injection mold

The secondary synchronous limiting ejection structure comprises a mold body, a mold core structure, a product forming groove and a secondary synchronous limiting ejection mechanism arranged at the side end of the mold body, and the secondary synchronous limiting ejection mechanism comprises a set of ejector pin rod body structures and reset spring bodies connected to the lower portions of the ejector pin rod body structures in a sleeving mode. The ejector pin rod body structure comprises an ejector pin rod structure, a spring limiting block arranged on the lower portion of the ejector pin rod structure and a double-head ejector pin body arranged on the upper portion of an ejector pin rod, the lower portion of the ejector pin rod is connected with the bottom plate structure of the mold body, and the double-head ejector pin and the inclined ejector are ejected out at the same time under the action of spring force during mold opening. When the dragging position of the double-head ejector pin is in contact with t
