The clamping assembly 26 is fixedly connected to the side surface of the moving plate 25, and the clamping assembly 26 clamps the traction belt 21 so that the moving plate 25 can move.

[0026] At the lower ends of the two moving plates 25, a plurality of connecting rods 27 are connected. The lower ends of the plurality of connecting rods 27 are fixedly connected to the upper end of the outer mold shell 23. The movement of the moving plate 25 drives the connecting rods 27 and the outer mold shell 23 to move. There are two inner molds 24, both of which are located inside the outer mold shell 23. The outer mold shell 23 and the inner mold 24 are both provided with injection ports 5, so that a grouting machine (not shown in the text) can inject cement into them. One end of the stretching rod 29 is connected to the inner mold 24, and the upper end of the stretching rod 29 is connected to the lateral moving device 28, so that the lateral moving device 28 can drive the inner mold 24 to move. The lateral moving device 28 is located between the two moving plates 25, and the upper end of the lateral moving device 28 is slidably connected to the fixed frame 1, so that the lateral moving device 28 can also move on the upper part of the fixed frame 1. The two outer mold shells 23 can be fixed by bolts.

[0027] The lateral moving device 28 includes: a second guide rail 281, a driving plate 282, a second electric cylinder 283, a central plate 286, a connecting rod 285 and a roller 284. The upper part of the fixed frame 1 is connected with a first guide rail 3. The roller 284 is slidably connected to the first guide rail 3, and the lower part of the roller 284 is connected to the connecting rod 285. The roller 284 drives the connecting rod 285 to move.

At this time, the traction belt 21 is clamped. Start the first electric cylinder 22 to drive the moving plate 25 and the outer mold shell 23 to move, so that the two half outer mold shells 23 are butted against each other. At this time, fix the outer mold shell 23 by means of bolts or the like. At this time, pour cement into the injection port 5. When the cement pouring is completed. When it is necessary to move the outer mold shell 23 and the injection molded part therein, start the third electric cylinder 261 to make the clamping plate 262 clamp the traction belt 21. At this time, start the first electric cylinder 22 to drive the traction belt 21 to move and drive the two half outer mold shells 23.
