The bottom inner wall of the fixed frame 1 is fixedly connected with a protective shell 8, which is used to protect the internal electric push rod 9 from external interference. The protective shell 8 is provided with an electric push rod 9 inside, which is used to push the gear 13 to move. The driving end of the electric push rod 9 is fixedly connected with a telescopic rod 10, which is used to transmit the power of the electric push rod 9. The other end of the telescopic rod 10 is fixedly connected with a disc 11, which is used to fix two fixed piles 12. The outer wall on the other side of the disc 11 is fixedly connected with two fixed piles 12, which are used to fix the gear 13 and enable the gear 13 to rotate. The outer wall on the adjacent side of the two fixed piles 12 is rotatably connected with the gear 13, which is used to drive the slide plate 16 to move. The bottom inner wall of the fixed frame 1 is fixedly connected with a rack plate 14 for driving the gear 13 to rotate. The bottom inner wall of the fixed frame 1 is fixedly connected with two slide plates 15. The slide plate 15 is used to provide a sliding track for the slide plate 16 to make the mold move on the X-axis. The inner walls of the two slide plates 15 are slidably connected with the slide plate 16. The top of the slide plate 16 is fixed with a sliding mechanism for adjusting the Y-axis orientation of the entire mold structure. The top of the slide plate 16 is fixedly connected with a detachable component for replacing molds of different shapes. Two limit piles 19 are fixedly connected to the left and right sides of the top of the slide plate 16 for fixing the threaded rod 20 to prevent the threaded rod 20 from moving horizontally. The inner walls of the two limit piles 19 are rotatably connected with the threaded rod 20, which is the driving source for driving the mold assembly to move on the Y-axis.

[0032] Reference Figure 2-Figure 4The detachable components include two slide plates 17, which provide sliding tracks for the movement of the slide plate 26. The inner walls of the two slide plates 17 are slidably connected with the slide plate 26. The mold component is fixed on the slide plate 26. When the template 2 slides, the mold is driven to move, thereby adjusting the position of the mold on the Y axis. The top of the slide plate 26 is fixedly connected with a fixing box 25, which is used to fix the mold. The interior is provided with a detachable component, and the mold can be replaced according to actual production requirements. The bottom inner wall of the fixing box 25 is fixedly connected with a fixing block 18, and the fixing block 18 is provided with a hole, which cooperates with the latch 23 to fix the lower mold 7. The top of the fixing block 18 is fixedly connected with the lower mold 7. The interior of the fixing box 25 is slidably connected with the latch 23, and a limiting ring is provided on the outside of the latch 23 for fixing the spring 24. The outer side of one end of the latch 23 is provided with a spring 24.

[0033] Reference Figure 1-Figure 3 The top inner wall of the fixed frame 1 is fixedly connected with an air pump 2 for driving the upper mold 6 to move. The bottom of the air pump 2 is fixedly connected with a telescopic column 3, and the telescopic column 3 drives the lower mold 7 to move. The outer side of the gear 13 is meshed with the top of the rack plate 14, and the outer side of the gear 13 is meshed with the bottom outer wall of the slide plate 16. When the gear 13 moves forward, the gear 13 is rotated by the rack plate 14, thereby driving the slide plate 16 to move on the X-axis. One end of the threaded rod 20 is fixedly connected with a turntable 21, and the outer side of the turntable 21 is fixedly connected with a handle 22. The threaded rod 20 is driven to rotate by turning the handle 22. The bottom of the slide plate 17 is fixedly connected to the top outer wall of the slide plate 16. The threaded rod The outer side of 20 is threadedly connected to the inner wall of the slide plate 26, so that when the threaded rod 20 rotates, the slide plate 26 is driven to move on the Y axis. One end of the pin 23 is slidably connected to the inside of the fixed block 18. The pin 23 cooperates with the fixed block 18 to make the lower mold 7 replaceable to adapt to different production needs. One end of the spring 24 is fixedly connected to the inner wall of the fixed box 25, and the other end of the spring 24 is fixedly connected to the limit block on the pin 23, thereby limiting the deformation of the spring 24. The bottom of the telescopic column 3 is fixedly connected with a fixed plate 4 for connecting the upper mold 6 with the telescopic column 3. The interior of the fixed plate 4 is threadedly connected with a plurality of screws 5, so that the upper mold 6 can be removed and replaced, and the bottom of the screws 5 is threadedly connected with the upper mold 6.

[0034] Working principle: When positioning the lower mold 7, turn on the electric push rod 9, the electric push rod 9 drives the telescopic rod 10 to move, the telescopic rod 10 drives the disc 11 to move, so that the fixed pile 12 moves, drives the gear 13 to move forward, and then through the meshing of the gear 13 and the rack plate 14, the gear 13 rotates, thereby driving the slide plate 16 to move along the slide groove on the slide groove plate, thereby driving the entire lower mold 7 structure to adjust the position on the X axis, and then by turning the handle 22, the handle 22 rotates to drive the disc 11 to rotate, thereby driving the threaded rod 20 to rotate. Since the limit pile 19 limits the horizontal movement of the threaded rod 20, Thereby, the slide plate 26 moves along the slide groove on the slide plate 2 17, and then the mold structure is adjusted on the Y-axis. After the position of the lower mold 7 is fixed, the air pump 2 is turned on. The operation of the air pump 2 drives the telescopic column 3 to move downward, thereby driving the upper mold 6 to move downward to carry out production operations. When the production process is completed, the latch 23 can be pulled, and the latch 23 moves outward to compress the spring 24. When the latch 23 moves out of the fixed block 18, the lower mold 7 can be taken out for replacement. After the replacement is completed, the latch 23 is released, and the spring 24 recovers its deformation to drive the latch 23 to slide into the fixed block 18, thereby fixing the new mold.
