Description

Technical Field

[0001] This utility model relates to the field of hydraulic press technology, and in particular to a quick mold changing device for a hydraulic press. Background Technology

[0002] Hydraulic press molds are heavy equipment. If people try to lift them during transport, it is difficult for one person to do so, and the equipment could fall and injure people. Therefore, a quick mold changing device is needed to transport and install the molds.

[0003] Currently, the molding and processing of safety door shells are all completed by hydraulic press using integral pressure molding. Since the surface of safety doors is relatively large, the molding molds are also relatively large and heavy. Existing technologies directly fix the molds on the upper and lower worktables. Because the molds are relatively heavy, the friction is large when placed directly on the worktable, and large auxiliary tools are needed to help push them into place. Changing molds is quite time-consuming and laborious.

[0004] Currently, Chinese utility model patent CN207372164U discloses a hydraulic press quick mold changing and labor-saving device, including a lower worktable and an upper fixed plate. The lower worktable and the upper fixed plate are connected by guide columns. A movable worktable is slidably mounted on the guide columns between the lower worktable and the upper fixed plate. A hydraulic cylinder is installed in the upper fixed plate to drive the movable worktable. Several rolling devices are evenly distributed on the panel of the lower worktable. The rolling device includes a cylinder installed in the panel. A roller seat is slidably mounted up and down in the cylinder. A roller is mounted on the upper end of the roller seat. A roller wheel is rotatably mounted on the roller. A roller pressure plate is also provided on the upper end of the roller seat to press the roller tightly on the roller seat. A guide rod is connected to the lower end of the roller seat. The guide rod slides out of the lower end of the cylinder. Several disc springs are installed on the guide rod between the lower end face of the roller seat and the cylinder. This utility model has a simple structure, is easy to manufacture and install, and saves labor and speeds up mold changing, thereby improving mold changing efficiency and reducing the labor intensity of mold changing.

[0005] To address the aforementioned issues, existing patents offer solutions. However, during the process of changing hydraulic press molds, the height of the hydraulic presses is usually not uniform, so workers often need to move the molds to a higher position before they can be changed. This not only increases the workload of the workers but also reduces the efficiency of the replacement process. Furthermore, the weight of the molds during transport can pose a safety hazard to the workers, thus failing to meet their usage needs.

[0006] To address this, a rapid mold-changing device for a hydraulic press is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a quick mold changing device for a hydraulic press, which can solve the problem that in the process of changing molds on a hydraulic press, the height of the hydraulic press is usually different, so the staff usually need to move the mold to a higher position before the mold can be changed. This not only increases the workload of the staff, but also reduces the efficiency of the staff. Moreover, the weight of the mold is usually heavy during the transportation process, which can easily cause safety hazards to the staff. Therefore, it cannot meet the needs of the staff.

[0026] 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.

[0027] Please see Figure 1-5The present invention provides the following technical solution:

[0028] A hydraulic press quick mold changing device includes a base plate 1, a lifting assembly 2 is provided on the inner side of the base plate 1, and a conveying assembly 3 is provided on the top of the lifting assembly 2.

[0029] The lifting assembly 2 includes a base 201, a drive motor 202, a bidirectional screw 203, a moving block 204, a connecting rod 205, and a connecting block 206. The base 201 is bolted to the inner side of the base plate 1, the drive motor 202 is bolted to the right side of the base plate 1, the bidirectional screw 203 is rotatably connected to the inner side of the base 201, and the right side of the bidirectional screw 203 is bolted to the output end of the drive motor 202. The moving block 204 is threaded to the outer side of the bidirectional screw 203, the bottom of the connecting rod 205 is rotatably connected to the inner side of the moving block 204, and the top of the connecting rod 205 is rotatably connected to the connecting block 206.

[0030] In this embodiment: by setting up a base plate 1, a lifting component 2, and a conveying component 3, the operator can raise and lower the mold to a position matching the height of the hydraulic press by activating the lifting component 2 on the top of the base plate 1. Then, by activating the conveying component 3, it is possible to replace the mold on the hydraulic press without the operator having to move the mold to a higher position before replacement. This not only reduces the workload of the operator but also improves the efficiency of the replacement process, making it more convenient for the operator to use. Furthermore, it allows the mold to be pushed into the hydraulic press for replacement after it has been raised to a suitable height, eliminating the need for the operator to push the mold into the hydraulic press for replacement and avoiding any safety hazards to the operator. Therefore, it meets the operator's usage needs.

[0031] Specifically, such as Figure 1 , Figure 3 As shown, the conveying assembly 3 includes a roller conveyor wheel 301, which is bolted to the top of the connecting block 206. A baffle 302 is bolted to the top of the roller conveyor wheel 301, and electric telescopic rods 303 are bolted to both sides of the baffle 302. A movable frame 304 is bolted to the telescopic end of the electric telescopic rod 303, and movable wheels 305 are bolted to the inner side of the movable frame 304.

[0032] Specifically, such as Figure 1 , Figure 3 As shown, an electric push rod 4 is bolted to the rear side of the baffle 302, and a push plate 5 is bolted to the front side of the electric push rod 4.

[0033] Specifically, such as Figure 1 , Figure 3 As shown, a protective pad 6 is glued to the front side of the push plate 5. The protective pad 6 is made of rubber.

[0034] In this embodiment: by setting up roller conveyor 301, baffle 302, electric telescopic rod 303, moving frame 304, moving wheel 305, electric push rod 4, push plate 5, and protective pad 6, the operator activates the electric telescopic rod 303 on both sides of the baffle 302 to drive the moving wheel 305 on the inner side of the moving frame 304 to limit the mold. Then, the roller conveyor 301 is activated to transport the mold. Therefore, the mold can be pushed into the hydraulic press for replacement after it is raised to a suitable height. Thus, the operator does not need to push the mold into the hydraulic press to replace it, and there is no safety hazard to the operator. Therefore, it meets the operator's needs. By setting up electric push rod 4 and push plate 5, the mold can be pushed, so the operator does not need to push it manually, which is convenient for the operator to use. By setting up protective pad 6, damage to the surface of the mold can be avoided during the pushing process.

[0035] Specifically, such as Figure 1 , Figure 4 As shown, a buffer spring 7 is bolted to the top of the base plate 1, and a damping rod is bolted to the inside of the buffer spring 7.

[0036] Specifically, such as Figure 1 , Figure 4 As shown, a push-pull handle 8 is bolted to the rear side of the base plate 1, and the surface of the push-pull handle 8 is provided with anti-slip texture.

[0037] In this embodiment: by setting a buffer spring 7, the force that the worker bears when placing the mold on the roller conveyor 301 can be buffered to avoid damage to the device. By setting a push-pull handle 8, it is convenient for the worker to push and pull the base plate 1, while preventing the worker's hand from slipping.

[0038] Specifically, such as Figure 5 As shown, lifting rods 9 are bolted to the bottom of the base plate 1, and limit plates 10 are bolted to the bottom of the lifting rods 9.

[0039] Specifically, such as Figure 1 , Figure 4 As shown, universal wheel bodies 11 are bolted to the bottom of the base plate 1, and the universal wheel bodies 11 are evenly distributed at the four corners of the bottom of the base plate 1.

[0040] In this embodiment: by setting the lifting rod 9 and the limiting plate 10, the base plate 1 can be limited during the mold changing process to avoid shaking. By setting the universal wheel body 11, it is convenient for the staff to move the mold changing device, so as to change the mold of the hydraulic press in different positions.

[0041] Working principle: During the process of changing the hydraulic press mold, the operator starts the drive motor 202 on the right side of the base 201 to drive the bidirectional screw 203 to rotate, thereby driving the moving block 204 to move in both directions, which in turn drives the connecting block 206 at the top of the connecting rod 205 to rise and fall. Therefore, it is possible to change the mold without the operator having to move it to a higher position, which not only reduces the workload of the operator but also improves the efficiency of the mold change, thus benefiting the operator's use. Then, the operator starts the electric telescopic rods 303 on both sides of the baffle 302 to drive the moving wheels 305 on the inner side of the moving frame 304 to limit the mold. Then, the roller conveyor 301 is started to transport the mold. Therefore, the mold can be pushed into the hydraulic press for change after it is raised to a suitable height. Thus, it is not necessary for the operator to push the mold into the hydraulic press for change, and it does not pose a safety hazard to the operator, thus meeting the operator's needs.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
