[0027] In this embodiment, Figure 1 As shown, a slot is provided at the center of the support plate 4; through this design, the ejection assembly 5 is moved by striking the impact block 2, so that the injection molded part can be ejected after molding and cooling, completing the discharge process.

[0028] In this embodiment, Figure 2 As shown, the ejector rod 503 forms an elastic structure through the first spring 504; through this design, the injection mold can eject the injection molded part by moving the ejector rod 503 after the injection molding is cooled, thereby completing the discharge process, and after the ejection is completed, the first spring 504 is extended, so that the ejector rod 503 can be retracted, so that subsequent injection molding work can be carried out, so that the injection molding work can be carried out continuously and uninterrupted, thereby increasing the production efficiency of the injection mold.

Heat is generated, thereby realizing a rapid cycle cooling process for the injection molded part. After cooling, the injection molded part contracts through the hydraulic rod 3, causing the impact rod 501 to impact the impact block 2, causing the connecting plate 502 to move together with the ejector rod 503. At this time, the first spring 504 will contract, thereby causing the ejector rod 503 to continue to move, and the injection molded part will be ejected through the slots of the fixed plate 701 and the pressing plate 703, so as to complete the discharge of the injection molded part. When the pressing plate 703 needs to be quickly disassembled, press the limiting buckle 704. At this time, the second spring 705 will contract, and the limiting buckle 704 will move horizontally. When the limiting buckle 704 is out of the groove in the middle of the fixed column 702, lift the pressing plate 703 and quickly disassemble the pressing plate 703.
