[0025] like Figure 1 and Figure 2As shown in the figure, this is an embodiment of the present invention, which relates to an auxiliary lifting mechanism for a mold, including a mechanism body 10. The mechanism body 10 includes a lifting platform 20, a scissor lift device 30, a drive device 40, and a base 50. The lifting platform 20 is located above the base 50 and is used to support the mold. The scissor lift device 30 is connected between the base 50 and the lifting platform 20 and is used to drive the lifting platform 20 to lift and lower to achieve height adjustment. The drive device 40 is connected to the scissor lift device 30 and is used to drive the scissor lift device 30 to move. Several support devices 60 are connected above the base 50, and several moving wheels 51 are provided below the base 50 for moving the mechanism body 10.

[0026] Specifically, the lifting platform 20, the scissor lift device 30, the drive device 40, and the base 50 work together to form a complete lifting, moving, and supporting functional system, laying the foundation for the overall performance of the mechanism and facilitating manufacturing and assembly.

[0027] Furthermore, the lifting platform 20 has several elongated through slots 21 in its center, which are arranged side by side. Specifically, the elongated through slots 21 reduce the weight of the lifting platform 20 itself and lower the load on the mechanism; on the other hand, they provide more possibilities for fixing the mold, such as fixing the mold by passing bolts or straps through the through slots, effectively improving the stability of the mold during transportation and preventing the mold from sliding or shifting.

[0028] Furthermore, the elongated slot 21 has gripping holes 22 on both sides, which are used to grip and push the mechanism body 10. Specifically, the gripping holes 22 provide the operator with a convenient point of force application, making it easy to manually push the mechanism when moving it a short distance or fine-tuning its position, making the operation more flexible and labor-saving.

[0029] Furthermore, several clearance slots 23 are provided on both sides of the lifting platform 20, and the clearance slots 23 are configured to cooperate with the support device 60. Specifically, the clearance slots 23 are precisely positioned to avoid the support device 60, ensuring no interference when the scissor lift device 30 retracts, effectively saving space, making the mechanism structure more compact, and ensuring smooth operation of all components.

[0030] Furthermore, the scissor lift device 30 includes multiple cross-connected links 31, which are interconnected through hinge points 32. Specifically, the scissor lift device 30 forms a stable mechanical structure through the cross-hinged connection of multiple links 31, which evenly distributes the load during lifting, ensuring smooth lifting of the lifting platform 20, possessing strong load-bearing capacity, and adaptable to molds of various weight specifications.

[0031] Furthermore, the drive device 40 includes two drive motors 41, a mounting plate 42, a lead screw 43, and a connecting plate 44. The two drive motors 41 are respectively mounted above the mounting plate 42. The mounting plate 42 is hinged to the inner side of the connecting rod 31. The lead screw passes through the mounting plate 42 and is electrically connected to the drive motors 41. The connecting plate 44 is connected to the lead screw 43, and both sides of the connecting plate 44 are connected to the connecting rod 31. Specifically, the drive device 40 adopts a design with dual drive motors 41 and lead screw 43 working together. The dual drive motors 41 provide sufficient power, and the lead screw 43 has high transmission accuracy, which can accurately control the movement of the scissor lift device 30, realize precise adjustment of the height of the lifting platform 20, and meet the precise height requirements of different working scenarios.

[0032] Furthermore, the number of the support devices 60 is set to four, and the four support devices 60 are respectively installed at the four corners above the base 50. Specifically, the four support devices 60 are distributed at the four corners of the base 50, following the principle of symmetrical distribution, so as to evenly distribute the supporting force, avoid excessive local stress, and significantly improve the overall stability of the mechanism when bearing the mold, which is especially suitable for supporting heavier molds.

[0033] Furthermore, the support device 60 includes an extension bracket 61 and a support hydraulic cylinder 70; one end of the extension bracket 61 is fixedly connected to the base 50; the support hydraulic cylinder 70 is used to contact the ground and provide adjustable and stable support. Specifically, the support device 60 includes an extension bracket 61 and a support hydraulic cylinder 70. The extension bracket 61 expands the support range, and the support hydraulic cylinder 70 can adjust the support height and force according to the actual ground conditions, which can adapt well to ground with different flatness and enhance the adaptability of the mechanism in complex working environments.

[0034] Furthermore, the supporting hydraulic cylinder 70 includes a cylinder body 71, a piston support rod 72, and a support seat 73. The cylinder body 71 is connected to or welded to the end of the extension bracket 61 opposite to the base 50 via a flange connection. The piston support rod 72 is movably connected to the cylinder body 71. The support seat 73 is connected to the bottom of the piston support rod 72. Specifically, the cylinder body 71, piston support rod 72, and support seat 73 of the supporting hydraulic cylinder 70 constitute a stable support structure. The cylinder body 71 is fixed to the extension bracket 61 via a flange connection or welding. The piston support rod 72 can flexibly extend and retract within the cylinder body 71. The support seat 73 increases the contact area with the ground, making the support process more stable and reliable.

[0035] Furthermore, the movable wheel 51 is a McClum caster, which enables the base 50 to rotate 360 ​​degrees horizontally. Specifically, the McClum caster allows the base 50 to rotate freely 360 degrees horizontally without the need for additional direction adjustments during movement. It can turn directly, making movement flexible and positioning precise, facilitating quick and accurate arrival at designated locations in complex workshop environments.

[0036] The working principle of this utility model is as follows:

[0037] When the mold needs to be lifted, the drive unit 40 is activated, and the two drive motors 41 drive the lead screw 43 to rotate. The lead screw 43 pushes the connecting plate 44, which in turn causes the connecting rod 31 of the scissor lift device 30 to extend or retract through the hinge point 32, driving the lifting platform 20 to rise or fall, achieving precise height adjustment. During mechanism movement, the 360-degree rotation characteristic of the McClum casters allows for easy and flexible movement of the mechanism body 10 without additional directional adjustments. Upon reaching the designated position, the support hydraulic cylinder 70 of the support device 60 begins to operate. The cylinder body 71 is fixed to the extension bracket 61, the piston support rod 72 extends, and the support seat 73 contacts the ground, providing adjustable and stable support. The gripping elongated hole 22 of the lifting platform 20 facilitates manual assistance in pushing the mechanism, and the clearance groove 23 ensures that the scissor lift device 30 precisely avoids the support device 60 when retracting, preventing interference and saving space. The elongated through-slot 21 not only reduces the platform's weight but also allows for further securing of the mold through additional methods (such as bolts passing through the through-slot or strapping), improving the mold's stability during transportation. Through the coordinated operation of all components, this mechanism achieves stable lifting, flexible movement, and precise positioning of the mold, efficiently completing mold-related tasks.

[0038] This invention achieves performance optimization in multiple dimensions through ingenious structural design. The clearance groove 23 of the lifting platform 20 avoids component interference, saves space, and improves the compactness of the mechanism; the elongated through groove 21 reduces the platform weight, enriches the mold fixing methods, and enhances transportation stability; the long gripping hole 22 optimizes the manual operation experience; the scissor lift device 30, in conjunction with the drive device 40, ensures smooth and precise lifting; four adjustable support hydraulic cylinders 70 ensure stable support under different ground conditions; and the McClum casters give the mechanism flexible mobility. Overall, this mechanism effectively meets the needs of various scenarios such as mold lifting, transportation, and installation, significantly improving operational efficiency and safety, and providing reliable support for mold-related operations.

[0039] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
