[0030] Through the ejection mechanism 4, the hydraulic cylinder 43 can push the push plate 44 upward, so that the push plate 44 can drive the push plate 49 to move synchronously through the ejector rod 410, and then the oil pan inside the mold groove 3 can be ejected. When people take out the oil pan, it saves time and effort, reduces people's labor, improves people's work efficiency, and thus improves the practicability of the device.
