[0031] 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.
[0032] Reference Figures 1 to 3This utility model provides an embodiment of a mold fixing bracket, including a lifting platform 1. Multiple fixing plates 2 are detachably connected to the top of the lifting platform 1. These fixing plates 2 are designed with flexible configuration options to adapt to luggage shells 16 of different sizes and shapes, thereby improving the versatility and applicability of the equipment. Support plates 3 are fixedly connected to both sides of the top of the fixing plates 2. The addition of the support plates 3 increases the overall stability and support capacity of the equipment, effectively preventing displacement of the luggage shell 16 during clamping. A limiting shaft 4 is threadedly connected to the adjacent side of the two support plates 3. The limiting shaft 4 ensures that the clamping block 5 maintains a stable axial position during rotation, thereby effectively preventing the clamping block 5 from becoming unstable due to excessive oscillation.
[0033] A clamping block 5 is externally connected to the limiting shaft 4. The clamping block 5 is designed to swing flexibly within a certain range to best fit the contour of the luggage shell 16, making the fixation tighter. The outside of the clamping block 5 contacts the adjacent side of the two support plates 3, ensuring that the clamping block 5 maintains stable contact and support during driving, avoiding damage caused by uneven clamping. Both sides of the clamping block 5 are provided with drive grooves 6, which allow the drive rod 7 to move smoothly within them, ensuring that the clamping block 5 can be reliably and flexibly adjusted according to the drive of the cylinder 14.
[0034] Two drive slots 6 are externally slidably connected to drive rods 7. The sliding of drive rods 7 allows clamping blocks 5 to swing outwards effectively, thereby achieving accurate clamping and fixation of the luggage shell 16. A reset assembly is provided on one side of clamping block 5. The reset assembly provides a reliable elastic reset mechanism, ensuring that clamping block 5 can automatically return to its initial position when the luggage shell 16 does not need to be fixed, avoiding deformation of clamping block 5 due to stillness. The reset assembly includes a fixing rod 8, which is externally fixedly connected to the adjacent side of the two support plates 3, providing a stable support point for the reset spring 9 to ensure the normal operation of the reset spring 9.
[0035] A return spring 9 is externally fixed to the fixing rod 8. The design of the return spring 9 allows the clamping block 5 to quickly and elastically return to its original position when the fixing to the luggage compartment shell 16 is removed, ensuring the efficiency and convenience of the equipment. A connecting plate 12 is fixedly connected to the other end of the return spring 9. The presence of the connecting plate 12 allows the force of the return spring 9 to be effectively transmitted to the clamping block 5, ensuring that the clamping block 5 can respond quickly and effectively reduce the time cost of operation. One side of the connecting plate 12 is fixedly connected to one side of the clamping block 5, forming a linkage structure, enabling the clamping block 5 to generate sufficient power during the reset process.
[0036] The external threaded connection of the limiting shaft 4 is secured with a nut 10. The design of the nut 10 facilitates later maintenance and disassembly, allowing users to easily perform routine inspections. One side of the nut 10 contacts one side of one of the support plates 3, enhancing the overall structural rigidity and ensuring the coordinated action between the various parts during clamping. A hydraulic cylinder 13 is detachably connected to the bottom of the lifting platform 1. The design of the hydraulic cylinder 13 provides necessary storage space for tools or accessories, improving overall ease of use.
[0037] Cylinders 14 are fixedly connected to the four corners of the inner wall of the lifting platform 1. The driving end of the cylinder 14 contacts one side of the drive rod 7. The driving of the cylinder 14 makes the entire clamping process more intelligent and automated, reducing the complexity of operation and labor intensity. The outer side of the fixing plate 2 has a groove 11. The design of the groove 11 allows the driving end of the cylinder 14 to effectively engage with the lifting platform 1, thereby providing a stable driving foundation and ensuring smooth operation of the equipment. The driving end of the cylinder 14 is slidably connected to the inner wall of the groove 11, ensuring that the cylinder 14 can move smoothly during operation and avoiding unnecessary vibration that affects the operation effect.
[0038] A hydraulic cylinder 13 is fixedly connected to the bottom of the lifting platform 1, and a support frame 15 is slidably connected to the outside of the lifting platform 1. The bottom of the hydraulic cylinder 13 is fixedly connected to the inner wall of the bottom of the support frame 15. The hydraulic cylinder 13 can drive the lifting platform 1 to move. Multiple fixing plates 2 are distributed at the four corners of the top of the lifting platform 1, which optimizes the clamping and differentiation capabilities. This allows the equipment to not only fix various types of luggage shells 16, but also ensures the flexible application of different clamping methods to adapt to different work needs. The luggage shell 16 is placed on the top of the lifting platform 1. One side of multiple clamping blocks 5 contacts the outside of the luggage shell 16 to form a stable fixing structure. Through the effective clamping of the clamping blocks 5, the luggage shell 16 remains stable during processing.
[0039] Working principle: When the equipment is needed, the luggage compartment shell 16 is placed on top of the lifting platform 1. Then, the cylinder 14 is activated, causing the piston rod to pass through the inner wall of the groove 11. The cylinder 14 then pushes the drive rod 7, which moves against the inner wall of the drive groove 6. At this time, the clamping block 5 rotates outside the limiting shaft 4, swinging outwards. This causes the clamping block 5 to protrude outwards past the fixing plate 2. The rotation of the clamping block 5 allows it to contact the inner wall of the luggage compartment shell 16. The wall is used to fix the luggage shell 16. When the clamping block 5 rotates, it drives the connecting plate 12 to rotate. The rotation of the connecting plate 12 can pull the return spring 9, causing the return spring 9 to deform and generate elastic potential energy. Thus, when the fixation of the luggage shell 16 is removed, the clamping block 5 can automatically return to its original position. The equipment is modularly designed. The fixing plate 2 is connected to the lifting platform 1 by bolts. The limiting shaft 4 can be pulled out by removing the nut 10, so that the clamping block 5 can be disassembled for easy inspection and maintenance.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
