However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a salt core pressing mold, including an operating table 1, a convenient disassembly assembly 2 is arranged inside the operating table 1, and the convenient disassembly assembly 2 includes a lower mold 201 and a screw groove 202, the lower mold 201 is arranged on the surface of the operating table 1, the screw groove 202 is opened inside the operating table 1, a one-way screw 203 is arranged inside the screw groove 202, a bearing 204 is arranged at one end of the one-way screw 203, a handle 205 is arranged at the other end of the one-way screw 203, two groups of moving blocks 206 are symmetrically arranged on the surface of the one-way screw 203, and a threaded hole is opened at the bottom of the moving block 206 207, an insert block 208 is provided on the inner side of the moving block 206, and sockets 209 are provided on both sides of the lower mold 201. The one-way screw 203 is fixedly connected to the handle 205, and the one-way screw 203 is rotatably connected to the bearing 204 through the screw groove 202. The one-way screw 203 is threadedly connected to the moving block 206 through the threaded hole 207. The position and size of the insert block 208 match the position and size of the socket 209, and the insert block 208 and the socket 209 are snap-fitted. The outer surfaces on both sides of the moving block 206 are in contact with the inner walls on both sides of the screw groove 202.

[0025] The effect achieved by the entire embodiment 1 is that when the lower mold 201 needs to be disassembled, the handle 205 can be rotated in the opposite direction, so that the handle 205 can drive the one-way screw 203 to rotate in the opposite direction in the screw groove 202, and then the one-way screw 203 can be threadedly rotated with the moving block 206 through the threaded hole 207, and drive the two groups of moving blocks 206 to move outward at the same time, and then drive the plug block 208 to be completely pulled out of the plug hole 209, and then the lower mold 201 can be directly removed from the surface of the operating table 1, thereby completing the rapid disassembly of the lower mold 201. After cleaning or repairing the lower mold 201, when the lower mold 201 needs to be installed and fixed, the lower mold 201 can be directly placed on the surface of the lower mold 201, and then the handle 205 is turned forward to drive the one-way screw 203 to rotate forward, so that the two sets of moving blocks 206 can move inward through the threaded holes 207, and drive the plug block 208 to be inserted into the plug hole 209 to fix the lower mold 201, thereby improving the convenience of disassembly and assembly of the lower mold 201, and avoiding the problem that the existing lower mold 201 is fixed by a large number of bolts and is very inconvenient during disassembly.

[0026] Embodiment 2, as Figure 1 , Figure 2 and Figure 5 As shown, a demoulding assembly 3 is arranged on the top of the operating table 1, and the demoulding assembly 3 includes an electric push rod 301 and a lifting plate 302. Two groups of electric push rods 301 are arranged on the inner bottom of the operating table 1, and the output ends of the two groups of electric push rods 301 are connected to the lifting plate 302. Four groups of push rods 303 are arranged on the top of the lifting plate 302. Top holes 304 are opened at the four corners inside the lower mold 201, and the two groups of electric push rods 301 are the same group of control switches.

[0027] The effect achieved by the entire embodiment 2 is that, after the lower mold 201 is fixed, the salt core can be added to the lower mold 201. When the electric push rod 301 is not started, the height of the push rod 303 is level with the height of the lower mold 201. After the salt core is added to the lower mold 201, it can be punched toward the lower mold 201 through the upper mold, so that the salt core mold is pressed into shape. After the salt core mold is pressed into shape, the lifting plate 302 can be pushed upward by the electric push rod 301, so that the lifting plate 302 can drive the push rod 303 to push the salt core mold out of the lower mold 201 through the top hole 304, thereby completing rapid demolding and avoiding the problem that the existing salt core mold is not easy to demold after being pressed into shape.

[0028] Working principle: When the lower mold 201 needs to be disassembled, the one-way screw 203 can be rotated to make the plug block 208 completely withdrawn from the socket 209, and then the lower mold 201 can be directly removed from the surface of the operating table 1, thereby avoiding the problem that the existing lower mold 201 is fixed by a large number of bolts and is very inconvenient to disassemble. After the salt core mold is pressed into shape, the electric push rod 301 can be used to push the push rod 303 to smoothly push the salt core mold out of the lower mold 201 to complete the rapid demolding, thereby avoiding the problem that the existing salt core mold is inconvenient to demold after pressing and forming.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
