[0023] First, the sand is fed into the molding groove 4 through the conveying pipe 13. Then, the first electric push rod 2 is activated to move the upper mold 3 down into the positioning ring 14 and the molding groove 4, thereby compressing and molding the sand. When demolding is required, the second electric push rod 6 is activated to move the demolding plate 7 up along the molding groove 4, thereby allowing the molded module to detach from the positioning ring 14. Then, with the help of the push plate 10, the molded module can slide down along the guide frame 15, thereby quickly demolding the module.

[0024] Example 2: Based on Example 1, a forming groove 4 is provided to facilitate the compression molding of sand. A support frame 5 is fixedly connected to the bottom of the processing table 1. A second electric push rod 6 is fixedly connected to the surface of the support frame 5. A template 7 seals the bottom of the forming groove 4. A positioning ring 14 is fixedly connected to the surface of the processing table 1. A guide frame 15 is provided on the surface of the processing table 1. The inner ring diameter of the positioning ring 14 is equal to the diameter of the forming groove 4.

[0025] In use, the sand material can first be fed into the molding groove 4. The positioning ring 14 can prevent the sand material from falling out of the molding groove 4 and play a limiting role. Then, the first electric push rod 2 can be activated to move the upper mold 3 down and extend into the positioning ring 14 and the molding groove 4 to compress and mold the sand material. After compression molding, the upper mold 3 is moved up. Then, the second electric push rod 6 can be activated to move the demolding plate 7 up, so that the compressed and molded module can be separated for quick demolding. The demolding plate 7 can seal and support the bottom of the molding groove 4 on the one hand, and facilitate subsequent quick demolding on the other hand.

The support rod 12 is fixedly connected to the inner ring surface of the bearing 11. The conveying pipe 13 is fixedly connected to the end face of the support rod 12 at an inclined angle. A discharge pipe 16 is provided at one end of the conveying pipe 13. A limit port is opened on the side of the discharge pipe 16. A sealing plate 17 is inserted into the limit port. A discharge hopper 18 is provided on the surface of the discharge pipe 16.

[0027] When in use, the sand can first be placed in the feeding hopper 18, and then the sealing plate 17 can be pulled out so that the sand can be fed from the feeding pipe 16 along the conveying pipe 13. The feeding hopper 18 can ensure that the amount of material fed each time is the same. After feeding, the support rod 12 can be rotated in conjunction with the bearing 11, so as to avoid the conveying pipe 13 from affecting the normal operation of the upper mold 3.
