Improved ejection mechanism

The utility model relates to the technical field of mold discharging, in particular to an improved ejection mechanism which comprises a lower mold and an auxiliary device, four guide columns are arranged on the inner wall of the lower mold, the surfaces of the guide columns are connected with a bottom plate in a sliding mode, and third springs are arranged on the surfaces of the guide columns in a sleeved mode. A third spring is arranged on the lower die, the two ends of the third spring are fixedly connected with the surface of the lower die and the surface of the bottom plate respectively, two ejector pin bodies are arranged on the surface of the bottom plate, and the auxiliary device is arranged on the surface of the bottom plate and comprises a hollow rod. According to the ejection mechanism, the phenomena that the blanking time is prolonged due to the fact that an existing ejection mechanism easily generates redundant stroke during ejection, and the service life is influenced due to the fact that a sprin
