Description

Technical Field

[0001] This utility model relates to the field of waterjet cutting technology, specifically a waterjet cutting quick mold changing and lifting mechanism. Background Technology

[0002] Waterjet cutting is an advanced machining process that uses high-pressure water jets (sometimes with added abrasive) to cut materials. It is widely used in the processing of various materials, including metals, stone, glass, and composite materials. With the increasing demands for production efficiency and processing precision in industrial production, waterjet cutting equipment is being used more and more extensively in aerospace, automotive manufacturing, and machining industries. During the use of waterjet cutting equipment, rapid mold changeover is one of the key aspects for improving production efficiency.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Traditional waterjet cutting equipment typically uses forklifts for mold changes. This method requires unloading the mold from the workbench, transporting it to a designated location by forklift, and then moving the new mold onto the workbench and securing it. This requires multiple people working together, involves complex procedures, is prone to errors, and results in long mold changeover times and low production efficiency. Furthermore, forklifts require significant operating space, and mold storage also occupies additional space. Frequent forklift movement increases safety hazards in the workshop, and the constant movement of forklifts increases the risk of collisions with other equipment and personnel, potentially leading to accidents. In addition, forklift mold changeovers are slow, failing to meet the demands of modern industrial production for rapid mold changes, thus reducing the production efficiency and operational safety of waterjet cutting equipment. Utility Model Content

[0005] The purpose of this invention is to provide a waterjet cutting quick mold changing and lifting mechanism to solve the problems mentioned in the background art, such as cumbersome operation, large space occupation, high safety hazards, and low mold changing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterjet cutting quick mold changing and lifting mechanism, comprising a worktable, cylinder mounting brackets installed on both sides of one end of the worktable, a lifting guide rod cylinder installed on one side of the cylinder mounting brackets, roller brackets installed at both ends of the top of the lifting guide rod cylinder, roller mounting base plates installed at the bottom of both sides of the inner wall of the roller brackets, a plurality of sliding rollers rotatably connected inside the roller brackets, a mold changing trolley provided on one side of the worktable, a plurality of feet installed at both ends of the top of the worktable, and a mold body provided on the top of the worktable.

[0007] More preferably, the mold-changing trolley is equipped with two hooks facing the same direction and two omnidirectional wheels with brakes.

[0008] More preferably, mold base plate support plates are welded to the bottom ends of both sides of the mold body.

[0009] In a further preferred embodiment, the lifting guide rod cylinder is fixed to the workbench by a cylinder mounting bracket, the roller bracket is lifted onto the lifting guide rod cylinder by welding or bolt connection, and the roller mounting base plate is fixed to the roller bracket by welding or bolt connection.

[0010] More preferably, the bottom of the mold body is provided with several grooves, and the internal size of the grooves is consistent with the external size of the feet.

[0011] More preferably, the sliding roller is made of high-strength alloy steel.

[0012] More preferably, the bottom of the mold base plate support plate is provided with a limiting groove, and the internal size of the limiting groove is consistent with the external size of the sliding roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This lifting mechanism, through the cooperation of lifting guide cylinders and sliding rollers, enables rapid lifting and ejection of molds, significantly shortening mold change time and improving mold change efficiency. This contributes to increasing the production efficiency of waterjet cutting equipment. Furthermore, it eliminates the need for forklifts for mold changes, reducing the demand for forklift operating space and mold storage space in the workshop, thus improving space utilization. It also avoids frequent forklift movement within the workshop, reducing the risk of collisions with other equipment and personnel, and enhancing production safety. The entire mold change process is simple and easy to operate, requiring only a few personnel, reducing labor intensity and improving operational convenience and reliability. In addition, this lifting mechanism is suitable for molds of various sizes and weights, exhibiting good versatility and adaptability, meeting the mold change requirements of different waterjet cutting equipment, and improving the production efficiency and operational safety of the waterjet cutting equipment.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 6 This utility model provides a technical solution: a waterjet cutting quick mold changing lifting mechanism, including a workbench 1, cylinder mounting brackets 2 are installed on both sides of one end of the workbench 1, a lifting guide rod cylinder 3 is installed on one side of the cylinder mounting bracket 2, roller brackets 4 are installed at both ends of the top of the lifting guide rod cylinder 3, roller mounting base plates 5 are installed at the bottom of both sides of the inner wall of the roller bracket 4, a plurality of sliding rollers 6 are rotatably connected inside the roller bracket 4, a mold changing trolley 7 is provided on one side of the workbench 1, a plurality of feet 8 are installed at both ends of the top of the workbench 1, and a mold body 9 is provided on the top of the workbench 1.

[0024] In this embodiment, as Figure 2 As shown, the mold changing trolley 7 is equipped with two hooks facing the same direction and two universal wheels with brakes.

[0025] In this embodiment, as Figure 5 As shown, mold base plate support plates are welded to the bottom ends of both sides of the mold body 9.

[0026] In this embodiment, as Figure 4 As shown, the lifting guide rod cylinder 3 is fixed on the workbench 1 by the cylinder mounting bracket 2, the roller bracket 4 is lifted onto the lifting guide rod cylinder 3 by welding or bolt connection, and the roller mounting base plate 5 is fixed onto the roller bracket 4 by welding or bolt connection.

[0027] In this embodiment, as Figure 5 As shown, the bottom of the mold body 9 has several grooves, and the internal size of the grooves is consistent with the external size of the foot 8.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, the sliding roller 6 is made of high-strength alloy steel.

[0029] In this embodiment, as Figure 5 As shown, a limiting groove is provided at the bottom of the mold base plate support plate, and the internal size of the limiting groove is consistent with the external size of the sliding roller 6.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the working process of this waterjet cutting quick mold changing and lifting mechanism is as follows:

[0031] First, when mold replacement is required, the lifting guide cylinder 3 is ventilated via a pneumatic cylinder, allowing it to lift the mold body 9 via the mold base plate support plate. The limiting groove at the bottom of the mold base plate support plate prevents the rollers and lifting guide cylinder 3 from having difficulty finding the lifting point of the mold body 9, thus ensuring a smooth lifting and mold replacement process. After lifting, the height of the mold body 9 is consistent with the height of the mold replacement trolley 7. Then, the mold replacement trolley 7 is pushed to the side of the workbench 1, so that the hooks on the mold replacement trolley 7 hook onto the feet 8 of the mold body 9 base plate, preventing the mold replacement trolley 7 from moving. Meanwhile, the mold changing trolley 7 is equipped with two universal wheels with brakes at the rear, which facilitates its movement and positioning in the workshop. Then, the mold body 9, after being lifted, is pushed onto the mold changing trolley 7 by the sliding rollers 6 to complete the quick mold change. The sliding rollers 6 are made of high-strength alloy steel, which has good wear resistance and rolling performance, and can bear the weight of the mold body 9 and achieve smooth sliding. Finally, the mold changing trolley 7 is pushed to the designated position, and the new mold is pushed onto the worktable 1. The air is released by the lifting guide cylinder 3 controlled by the cylinder, so that the new mold is lowered onto the worktable 1, completing the entire mold changing process.
