Through the protection seats 9, the first hydraulic telescopic rods 7 can be protected, so as to prevent damage in the use process.
[0026] The telescopic end of each group of first hydraulic telescopic rods 7 is fixedly connected with a sliding plate 8, the telescopic end of each group of second hydraulic telescopic rods 11 is fixedly connected with a movable plate 5, the outer surface of the telescopic end of each group of first hydraulic telescopic rods 7 is fixedly connected with a fixed plate 10, and the bottom surface of each fixed plate 10 is fixedly connected with the upper surface of the sliding plate 8. Through the fixed plate 10, the first hydraulic telescopic rod 7 and the sliding plate 8 can be reinforced, and the stability of the device is enhanced.
[0027] The bottom surface of each movable plate 5 is fixedly connected with a first limiting plate 15, the bottom surface of each sliding plate 8 is fixedly connected with a second limiting plate 16, the outer surface of each group of supporting plates 2 is provided with two grooves 17, the outer surface of each group of second hydraulic telescopic rods 11 is fixedly connected with two dustproof shells 12, and the upper surface of each group of dustproof shells 12 is fixedly connected with the bottom surface of the top plate 3. Through the dustproof shell 12, the second hydraulic telescopic rod 11 can be protected, and external interference during use can be prevented.
[0028] The inner wall of each group of grooves 17 is fixedly connected with two third hydraulic telescopic rods 18, the telescopic end of each group of third hydraulic telescopic rods 18 is fixedly connected with two movable frames 19, the outer surface of the telescopic end of each group of second hydraulic telescopic rods 11 is fixedly connected with two reinforcing plates 13, and the bottom surface of each group of reinforcing plates 13 is fixedly connected with the upper surface of the movable plate 5.

Then, by extending the telescopic end of the first hydraulic telescopic rod 7, the sliding plate 8 is driven to descend, thereby driving the second limiting plate 16 to descend, thus fixing and clamping the mold body 6. Then, by extending the telescopic end of the second hydraulic telescopic rod 11, the movable plate 5 is driven to descend, and then the first limiting plate 15 is driven to descend, thereby fixing the position of the mold body 6.

This effectively avoids the problem that the device can only fix and clamp the mold, but when different models are produced, the mold needs to be replaced, and the inability to quickly fix the mold can easily lead to a decrease in production efficiency.
