[0026] In order to provide a hydraulically driven mechanism on the injection mold, the molding cavity in the injection molding device can be pulled out from the mold, which is convenient for maintenance and replacement of the molding cavity. Figure 1-3 As shown, the injection molding device with a hydraulic drive mechanism described in the utility model comprises an upper mold 1, a lower mold 2, a molding cavity 3, a connecting rod 4 and a hydraulic push rod 6. A feeding port 8 is provided on one side of the top of the upper mold 1, a lower mold 2 is provided at the lower end of the upper mold 1, and a molding cavity 3 is embedded in the lower mold 2;

[0027] A hydraulic push rod 6 is provided at one end of the lower mold 2, and a connecting rod 4 is connected to the driving end of the hydraulic push rod 6. One end of the connecting rod 4 is connected to the molding cavity 3 through a connecting plate 16 and a screw. Slide blocks 10 are provided on both sides of the molding cavity 3. Slide grooves 11 are opened on both sides of the inner wall of the lower mold 2, and the slide blocks 10 are located inside the slide grooves 11.

[0028] When in use, the hydraulic push rod 6 can pull the molding cavity 3 through the action of the connecting rod 4, and the molding cavity 3 can move smoothly through the cooperation of the slider 10 and the slide groove 11, so that the molding cavity 3 can be pulled out from the inside of the lower mold 2;

[0029] When the connecting rod 4 drives the forming cavity 3 to move, the limiting sleeve 5 can limit and guide the connecting rod 4;

[0030] The connecting rod 4 is connected to the molding cavity 3 through the connecting plate 16 and screws, and is easy to disassemble, which is beneficial for personnel to maintain and replace the molding cavity 3.

[0031] For example, Figure 1 , Figure 3 As shown, both sides of the upper mold 1 are provided with carrying handles 15 , and both ends of the carrying handles 15 on both sides of the upper mold 1 are provided with hanging holes 14 .
