[0007] As a further technical solution of this utility model, the movable plate slides left and right inside the movable sleeve, and the movable plate is fixed inside the movable sleeve by a fixing pin and an adjustment hole.

[0008] As a further technical solution of this utility model, side plates are fixedly connected to the left and right sides of the top of the base, servo motors are installed at the front and rear ends of the right side of the base, worm gears are fixedly connected to the output ends of the servo motors, threaded rods are movably connected to the front and rear ends inside the side plates, worm wheels are installed at the bottom of the threaded rods, threaded sleeves are provided on the outside of the threaded rods, and support blocks are fixedly connected to the side of the threaded sleeves near the middle. The support blocks are located on the left and right sides of the bottom of the support frame, and fixing bolts are provided at the front and rear ends inside the threaded sleeves. The support frame is fixed to the top of the support blocks by fixing bolts.

[0009] As a further technical solution of this utility model, the threaded rod and the threaded sleeve cooperate with each other, and the worm wheel and the worm cooperate with each other.

[0010] As a further technical solution of this utility model, a hydraulic cylinder is installed at the middle position of the bottom of the base, an anti-slip plate is installed at the bottom of the hydraulic cylinder, an anti-slip pad is installed at the bottom of the anti-slip plate, guide rods are installed at the four corners of the top of the anti-slip plate, and guide grooves are opened at the four corners inside the base.

[0011] As a further technical solution of this utility model, the guide rod is disposed inside the guide groove, and the guide rod slides up and down inside the guide groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the mold changing trolley with the push-pull mechanism not only makes it easy to push and pull the limiting plates to adjust the distance between the limiting plates and makes it easy to lift and lower the frame, but also makes it easy to limit and fix the base.

[0013] (1) By setting a fixed pin, a limiting plate, a movable plate, a movable sleeve and an adjustment hole, when it is necessary to adjust the distance between the limiting plates, the fixed pin is taken out from the inside of the adjustment hole. After taking it out, push the limiting plate so that the movable plate on one side of the limiting plate slides inside the movable sleeve, so that the limiting plate is close to the mold and clamps and limits the mold. After adjustment, insert the fixed pin into the adjustment hole again to limit and fix the movable plate, so as to prevent the movable plate from accidentally sliding inside the movable sleeve and affecting the limiting plate's limiting of the mold.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The present invention provides an embodiment of a mold changing vehicle with a push-pull mechanism, comprising a base 1, push handles 8 fixedly connected to the left and right sides of the top front end of the base 1, casters 2 installed at the four corners of the bottom end of the base 1, a support frame 7 provided at the top of the base 1, a movable roller 11 movably connected inside the support frame 7, a movable sleeve 13 fixedly connected to the top of the movable roller 11, a movable plate 12 sliding inside the movable sleeve 13, a limit plate 10 fixedly connected to the side of the movable plate 12 near the middle, and adjustment holes 23 opened at the front and rear ends inside the movable plate 12, with fixing pins 9 provided inside the adjustment holes 23.

[0023] The movable plate 12 slides left and right inside the movable sleeve 13. The movable plate 12 is fixed inside the movable sleeve 13 by the fixing pin 9 and the adjusting hole 23.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, when it is necessary to adjust the distance between the limiting plates 10, the fixing pin 9 is taken out from the inside of the adjusting hole 23. After taking it out, the limiting plate 10 is pushed so that the movable plate 12 on one side of the limiting plate 10 slides inside the movable sleeve 13, so that the limiting plate 10 is close to the mold to clamp and limit the mold. After adjustment, the fixing pin 9 is inserted into the adjusting hole 23 again to limit and fix the movable plate 12, so as to prevent the movable plate 12 from accidentally sliding inside the movable sleeve 13 and affecting the limiting plate 10 to limit the mold.

[0025] Side plates 3 are fixedly connected to the top left and right sides of the base 1. Servo motors 15 are installed at the front and rear ends of the right side of the base 1. Worm gears 21 are fixedly connected to the output end of the servo motors 15. Threaded rods 4 are movably connected to the front and rear ends inside the side plates 3. Worm gears 22 are installed at the bottom of the threaded rods 4. Threaded sleeves 5 are provided on the outside of the threaded rods 4. Support blocks 20 are fixedly connected to the side of the threaded sleeves 5 near the middle. Support blocks 20 are located on the left and right sides of the bottom of the support frame 7. Fixing bolts 6 are provided at the front and rear ends inside the threaded sleeves 5. The support frame 7 is fixed to the top of the support blocks 20 by fixing bolts 6. Threaded rods 4 and threaded sleeves 5 cooperate with each other, and worm gears 22 and worm gears 21 cooperate with each other.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when the height of the top mold of the movable roller 11 needs to be adjusted according to the requirements, the servo motor 15 is started. The servo motor 15 drives the worm wheel 22 to rotate through the worm 21. The rotation of the worm wheel 22 can drive the threaded rod 4 to rotate. The rotation of the threaded rod 4 can cause the threaded sleeve 5 to drive the movable roller 11 to rise and fall through the support block 20 and the support frame 7, so that the height of the mold can be adjusted according to the requirements, which facilitates mold replacement.

[0027] A hydraulic cylinder 14 is installed at the middle position of the bottom of the base 1. An anti-slip plate 16 is installed at the bottom of the hydraulic cylinder 14. An anti-slip pad 18 is installed at the bottom of the anti-slip plate 16. Guide rods 17 are installed at the four corners of the top of the anti-slip plate 16. Guide grooves 19 are opened at the four corners inside the base 1. The guide rods 17 are set inside the guide grooves 19 and slide up and down inside the guide grooves 19.

[0028] Specifically, such as Figure 1 and Figure 2As shown, after the mold changing trolley is pushed to the appropriate position, the hydraulic cylinder 14 is activated. The hydraulic cylinder 14 drives the anti-slip plate 16 and anti-slip mat 18 to descend, so that the anti-slip plate 16 and anti-slip mat 18 contact the ground and limit the caster 2 and base 1, preventing the caster 2 from causing the base 1 to slide and affecting the mold changing. When the anti-slip plate 16 descends, the guide rod 17 slides up and down inside the guide groove 19, which can limit the anti-slip plate 16 and improve the stability of the lifting and lowering of the anti-slip plate 16.

[0029] Working principle: When using this invention, the mold is placed on the top of the movable roller 11. When the distance between the limiting plates 10 needs to be adjusted, the fixing pin 9 is taken out from the inside of the adjustment hole 23. After taking it out, the limiting plate 10 is pushed so that the movable plate 12 on one side of the limiting plate 10 slides inside the movable sleeve 13, so that the limiting plate 10 is close to the mold and clamps and limits the mold. After adjustment, the fixing pin 9 is inserted into the adjustment hole 23 again to limit and fix the movable plate 12, preventing the movable plate 12 from accidentally sliding inside the movable sleeve 13 and affecting the limiting plate 10's limiting of the mold. When the height of the mold at the top of the movable roller 11 needs to be adjusted according to requirements, the servo motor 15 is started. The servo motor 15 drives the worm gear 21. The rotation of wheel 22 and worm gear 22 can drive the threaded rod 4 to rotate. The rotation of threaded rod 4 can cause threaded sleeve 5 to drive movable roller 11 to rise and fall through support block 20 and support frame 7. This allows the height of the mold to be adjusted as needed, facilitating mold replacement. After the mold changing trolley is pushed to the appropriate position, hydraulic cylinder 14 is activated. Hydraulic cylinder 14 drives anti-slip plate 16 and anti-slip mat 18 to descend, so that anti-slip plate 16 and anti-slip mat 18 contact the ground and limit the caster 2 and base 1, preventing the caster 2 from causing the base 1 to slide and affecting mold replacement. When anti-slip plate 16 descends, guide rod 17 slides up and down inside guide groove 19, thereby limiting anti-slip plate 16 and improving the stability of anti-slip plate 16 rising and falling.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
