[0023] The following is a detailed description of the specific settings and functions of this embodiment. The mold is placed on the punch 33, and the outer template 2 is placed on the bottom plate 31, and the limit blocks 32 are used to position the corners. The bottom plate 31 is then lifted by controlling the hydraulic cylinder 3 to make the top surface of the outer template 2 fit with the bottom surface of the sand adding bin 1 for sand filling. After the discharge is completed, the outer template 2 is controlled to fall, and the rotating connecting plate 53 is coordinated to rotate to control the frame plate 51 and the pre-pressing plate 52 to move to the top of the outer template 2 for compaction. The hydraulic cylinder 3 is used to lift the sand material in the outer template 2 to quickly complete the sanding and compacting operations, thereby improving the processing efficiency. In the process of sand adding operation, contact feeding is used to avoid generating a large amount of dust, thereby reducing the pollution of sand mold molding.

[0024] Example 2: Figure 1 - Figure 4 As shown, a support plate 11 is fixedly connected to the outer wall of one side of the sand adding silo 1, a drive motor 12 is installed on the outer wall of the other side of the sand adding silo 1, a discharge box 14 is fixedly connected to the inner wall of the sand adding silo 1, a guide plate 13 is fixedly connected between the top of the discharge box 14 and the inner wall of the sand adding silo 1, a discharge wheel 15 is arranged inside the discharge box 14, the shaft end of the discharge wheel 15 is fixedly connected to the output shaft end of the drive motor 12, a spring 55 is fixedly connected between the outer wall of the compacting plate 54 and the inner wall of the frame plate 51, a vibration motor 56 is installed on the top surface of the compacting plate 54, an edge pressing plate 57 is fixedly connected to the bottom surface of the pre-pressing plate 52, the outer walls of the four corners of the bottom plate 31 are fixedly connected to the limiting block 32, and the outer wall of the outer template 2 is movably connected to the outer wall of the limiting block 32.
