[0025] Furthermore, the air pump 20 is electrically connected to the control panel 21. The electrical connection relationship and control method between them are known technologies, so they will not be described in detail.

[0026] Specifically, such as Figures 1-3 As shown, the components include a horizontal plate 5, air pipe 1 6, upper nozzle 7, air pipe 2 8, lower nozzle 9, slide groove 1 10, slider 11, hose 18, tee connector 19, air pump 20, control panel 21, fixed base 22, push-pull rod 23, connecting base 24, and slide groove 25. When the molding model is in use, the compressed air can be sent into the air pipe 1 6 and air pipe 2 8 through the hose 18 by controlling the air pump 20 to start the model. The compressed air can then be sprayed out through several upper nozzles 7 and lower nozzles 9 onto the bottom surface of the upper mold body 4 and the top surface of the lower mold body 2. Then, the horizontal plate 5 can be pushed back and forth between the lower mold body 2 and the upper mold body 4 by using the push-pull rod 23, which facilitates the convenient blowing and cleaning of the contact surface between the upper and lower molds inside the model.

[0030] Working principle: When using the molding model, the air pump 20 can be started to send compressed air into the air pipe 6 and air pipe 8 through the hose 18. The compressed air can then be sprayed out through several upper nozzles 7 and lower nozzles 9 onto the bottom surface of the upper mold body 4 and the top surface of the lower mold body 2. Then, by using the push-pull rod 23, the horizontal plate 5 can be pushed back and forth between the lower mold body 2 and the upper mold body 4 to easily blow and clean the contact surface between the upper and lower molds inside the model. In addition, during the use of the molding model, the screw 13 can be driven to rotate by turning the handle 14 at the bottom of the lower mold body 2. The screw 13 rotates in the threaded hole 12, which can drive the movable seat 27 to move up and down inside the lower mold cavity 26. By adjusting the molding space inside the lower mold cavity 26, the molding length of the screw can be easily adjusted.
