[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] like Figures 1-4 As shown, this utility model discloses a mold changing tool cart, including a box 1, which is rectangular in shape, and four universal casters 2 are provided at the bottom of the box 1 so that the box 1 can move.

[0032] A drawer 4 is slidably provided on the top of the box body 1, and tools can be placed in the drawer 4. The drawer 4 includes a drawer surface 41 as the outer wall, and two drawers 42 are provided in the drawer surface 41. Tools are placed in the two drawers 42, and there is a gap between the two drawers 42.

[0033] One side wall of the box 1 at the bottom of drawer 4 is an open surface. The middle of the box 1 at the bottom of drawer 4 is provided with a horizontal second-level platform 3. Items can be placed on the second-level platform 3 and the bottom surface of the box 1 below the second-level platform 3.

[0034] The upper part of the box 1 is provided with a support platform 5, and the bottom of the support platform 5 is vertically connected to an adjusting screw 6. The center of the top surface of the box 1 is provided with a screw hole that is threaded to the adjusting screw 6. Rotating the adjusting screw 6 to make it threaded to the screw hole realizes the lifting and lowering of the support platform 5. During the process of the adjusting screw 6 descending and extending into the box 1, the adjusting screw 6 slides through the gap between the two drawers 42, and the drawer 4 will not obstruct the lifting and lowering of the adjusting screw 6.

[0035] The top of the support platform 5 has multiple through holes 7 arranged in a matrix. The support platform 5 inside the area where the through holes 7 are arranged has a cavity. A universal ball 12 is installed in the cavity inside the through hole 7. The universal ball 12 is rolled on the ball seat 13. When the ball seat 13 rises, the universal ball 12 can be exposed outside the through hole 7. When the ball seat 13 falls, the universal ball 12 can be retracted into the inside of the through hole 7.

[0036] The cavity of the support platform 5 is provided with a lifting plate 14, and multiple ball seats 13 are provided on the lifting plate 14. The support platform 5 is provided with a drive assembly for driving the lifting plate 14 to rise and fall.

[0037] The drive assembly includes four lifting screws 15. The bottom of the support platform 5 has four threaded holes that engage with the lifting screws 15. The top ends of the lifting screws 15 extend into the cavity and are rotatably connected to the bottom of the lifting plate 14. The bottom ends of the lifting screws 15 are located below the support platform 5, and knobs 16 are coaxially connected to the bottom ends of the lifting screws 15. Rotating the knobs 16 of the four lifting screws 15 engages the threaded holes to achieve lifting and lowering, thereby driving the lifting plate 14 to rise and fall.

[0038] A telescopic frame is slidably installed inside the second-level platform 3. The telescopic frame can extend and retract from the opening surface of the box 1 on the side of the second-level platform 3. The telescopic frame includes two horizontally sliding telescopic rods 9 inside the second-level platform 3. Correspondingly, the second-level platform 3 has rod grooves 17 for the telescopic rods 9 to slide. The opening end of the rod groove 17 is located on the opening surface side of the box 1. The ends of the two telescopic rods 9 away from the second-level platform 3 are connected to a vertically arranged support frame 10. The bottom end of the support frame 10 is rotatably connected to a locking caster 11, which has a braking mechanism to lock.

[0039] The bottom of the housing 1 has a groove 8 on the edge of the opening surface, which corresponds to the locking caster 11. When the telescopic frame is retracted into the housing 1, the locking caster 11 slides into the groove 8, so that the locking caster 11 is located on the inner side of the bottom of the housing 1.

[0040] The inner diameter of the rod groove 17 is larger than the outer diameter of the telescopic rod 9. A limiting ring 19 is provided on the inner edge of the opening end of the rod groove 17. The inner diameter of the limiting ring 19 is adapted to the outer diameter of the telescopic rod 9. A limiting block 18 adapted to the inner diameter of the rod groove 17 is connected to the inner end of the telescopic rod 9. The cooperation between the limiting block 18 and the limiting ring 19 prevents the telescopic rod 9 from sliding out of the rod groove 17.

[0041] The telescopic rod 9 is equipped with a locking assembly, which allows the telescopic rod 9 to be fixed after it is extended. The locking assembly includes a plate groove 21 opened on the telescopic rod 9. The plate groove 21 is opened radially along the telescopic rod 9. A locking plate 20 is slidably arranged in the plate groove 21. The locking plate 20 is arranged radially along the telescopic rod 9 and parallel to the axial direction of the telescopic rod 9. A spring 22 is provided between the bottom of the locking plate 20 and the inner end of the plate groove 21. An external protrusion is provided at the bottom end of the side wall of the locking plate 20, making the bottom end of the locking plate 20 an enlarged structure. An internal protrusion is provided at the corresponding position at the top of the plate groove 21, which cooperates with the external protrusion at the bottom end of the side wall of the locking plate 20. When the locking plate 20 rises to the top of the plate groove 21, most of the locking plate 20 is exposed outside the plate groove 21. The external protrusion at the bottom end of the side wall of the locking plate 20 contacts the internal protrusion at the top of the plate groove 21 to limit the locking plate 20. The part of the locking plate 20 exposed outside the plate groove 21 is arc-shaped, and the arc trajectory is towards the side away from the rod groove 17.

[0042] When the telescopic rod 9 slides within the rod groove 17, the locking plate 20 is inside the plate groove 21, and the spring 22 is compressed. When the telescopic rod 9 extends to its maximum stroke, the limiting block 18 contacts the limiting ring 19, and the locking plate 20 is outside the rod groove 17. The elastic force of the spring 22 drives the locking plate 20 to slide upward to its maximum stroke. The non-arc side of the locking plate 20 abuts against the second-layer platform 3 outside the rod groove 17. At this time, the telescopic rod 9 is fixed and cannot extend or retract. When the telescopic rod 9 retracts into the rod groove 17, pressing the locking plate 20 causes it to enter the plate groove 21. The locking plate 20 no longer abuts against the side of the second-layer platform 3, allowing the telescopic rod 9 to retract into the rod groove 17.

[0043] During mold changing operations, move housing 1 to the equipment location, extend the telescopic frame and secure the locking casters 11. Adjust the height of the support platform 5 using the adjusting screw 6 to match the mold height, bringing the support platform 5 close to the mold. Then, move the mold onto the support platform 5. The universal balls 12 on the support platform 5 allow the mold to slide, improving mold transfer efficiency. Once the mold is on the support platform 5, rotate the knob 16 to lower the lifting screw 15, causing the lifting plate 14 to retract the universal balls 12 into the through holes 7, ensuring the mold contacts the support platform 5 and preventing it from slipping. Place the new mold on the telescopic frame. After transferring the mold from the support platform 5, rotate the knob 16 to expose the universal balls 12 in the through holes 7, then place the new mold on the support platform 5. Move the new mold using the support platform 5 until it is moved into the equipment. After mold changing is complete, retract the telescopic frame into housing 1 and then remove housing 1.

[0044] This utility model facilitates the movement and loading of tools, has a compact structure, and provides a support surface for mold transfer when changing molds. The height of the support platform 5 can be adjusted to match the mold height, greatly improving the efficiency of mold changing operations. The universal ball 12 on the support platform 5 can be exposed or retracted, enabling the support platform 5 to slide and transfer the mold or prevent it from slipping when placing the mold.

[0045] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
