The elastic component is positioned between the upper pressing plate 15 and the lower pressing plate 50, the lower pressing plate 50 is provided with the pressure receiving plate 41 of the box cover 40, the box cover 40 is covered on the sand box 30, the lifting plate 20 moves upwards to be in contact with the lower pressing plate 50, and the elastic component 51 squeezes the lower pressing plate 50 to push the box cover 40 into the sand box 30. The support frame 10 further comprises an air inlet pipe 12 and an air outlet pipe 13, one end of the air inlet pipe 12 is communicated with one end of the air outlet pipe 13, the other end of the air inlet pipe 12 is communicated with an air pump, the lifting pipe 21 is fixedly connected to the lifting plate 20, the other end of the air outlet pipe 13 is inserted into the lifting pipe 21, the outer surface of the air outlet pipe 13 is coupled with the inner surface of the lifting pipe 21, the air outlet pipe 13 is fixed to the support plate 11, the air pump is started, the lifting plate 20 moves upwards, the air pump is stopped, and the lifting plate 20 moves downwards.

By arranging the elastic component 51 between the upper pressing plate 15 and the lower pressing plate 50, when the lower pressing plate 50 presses the box cover 40, the box cover 40 is stressed more uniformly; after the sand in the sand box 30 is tightly compressed, the pressure is absorbed by the elastic member 51, and the elastic member 51 is deformed, thereby protecting the sand box 30 from being damaged.

The elastic member 51 may be a spring, rubber, or a sleeper having a certain elasticity, and when the elastic member 51 is a spring, the number of the bolts 52 is four.
