Description

[0001] The utility model relates to the technical field of presses, in particular to a die fixing device for a press. Background Art

[0002] In the fields of metal forming, machinery manufacturing and automobile manufacturing, presses, as core equipment, play a vital role. They can form raw materials into preset shapes and specifications by applying strong pressure. In this process, the mold is a key component of the press, and the design of its fixing device is particularly important.

[0003] Traditional mold fixtures are usually complicated, the installation process is cumbersome, and the adjustment is not convenient enough, which not only increases the operation time and difficulty and reduces production efficiency, but also in some cases may cause the mold to shift or loosen, thereby affecting the quality and safety of the product. For manufacturers, the mold fixture not only needs to withstand huge pressure and friction, but also ensure that the mold remains stable during long-term work. Therefore, it is very important to design a new type of mold fixture for presses.

[0004] Chinese patent document CN216373472U discloses a mold fixing device for a press machine, including a press machine body, the press machine body including a pressure column and a workbench, the workbench is arranged below the press machine body, a hydraulic cylinder is fixedly installed above the press machine body, one side of the hydraulic cylinder is fixedly connected to an oil inlet pipe, one end of the oil inlet pipe is fixedly connected to an oil supply tank, a fixing device is fixedly installed on the surface of the workbench, and a protective device is arranged on the outside of the press machine body; however, the following defects still exist in the implementation process:

[0005] Although the device in the above-mentioned document can be clamped to the mold by a fixed fixture and can be reset by a reset assembly when the mold is formed so as to fix and clamp the next mold, the clamping of the mold in the above-mentioned document is too simple, and only one side of the mold is clamped, which causes the mold to easily deviate from its position under the pressure of the press, thereby affecting the quality and safety of the product. In addition, the device in the above-mentioned document cannot adjust the clamping position height of the mold according to actual requirements. Summary of the invention

[0006] The purpose of the utility model is to provide a die fixing device for a press machine to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] A mold fixing device for a press comprises a support frame; a lifting structure is fixedly connected to the lower part of the support frame, a protective cover 1 is fixedly connected to one side of the support frame, a protective cover 2 is fixedly connected to the side of the support frame away from the protective cover 1, a clamping structure is arranged in the middle of the support frame, the clamping structure is used to fix the mold, an upper cover is fixedly connected to the upper end of the support frame, two telescopic rods are symmetrically fixedly connected to the support frame, a press body is arranged in the middle of the upper cover, the press body is used to perform pressure molding on the mold, and the output ends of the two telescopic rods are fixedly connected to the press body.

[0009] A further improvement of the technical solution of the utility model is that the lifting structure includes a workbench, the outer surface of the workbench is fixedly connected to the lower part of the support frame, a storage groove is opened in the middle of the workbench, a hydraulic cylinder is fixedly connected to the bottom wall of the inner cavity of the storage groove, a telescopic rod is symmetrically fixedly connected to the bottom wall of the inner cavity of the storage groove, and a connecting plate is fixedly connected to the output end of the hydraulic cylinder and the output ends of the two telescopic rods.

[0010] The above technical solution is adopted, in which the connecting plate is driven to rise and fall in the inner cavity of the storage groove by the output end of the hydraulic cylinder piston rod, so that the height position of the mold placed above the connecting plate can be accurately adjusted, so that the device can adjust the clamping position height of the mold according to actual requirements.

[0011] A further improvement of the technical solution of the utility model is that the clamping structure includes two connecting shells, the inner cavities of the two connecting shells are slidably connected with the driving structure, the opposite surfaces of the two driving structures are commonly fixedly connected with a clamping plate, and the upper end of one of the connecting shells is fixedly connected with a motor.

[0012] The above-mentioned technical solution is adopted, in which two clamping plate components cooperate with each other to form a stable supporting structure, which can adapt to molds of different sizes. During the operation of the press, the mold is subjected to strong pressure, and this pressure may cause the position of the mold to shift. However, through the cooperation and fixation of the two clamping plate components, this pressure can be effectively resisted to ensure the stability of the position of the mold during the molding process. In addition, by adjusting the distance between the two clamping plate components, the device can adapt to molds of different sizes to meet different production needs. This not only improves the versatility and flexibility of the equipment, but also reduces the problems and production costs caused by mold size mismatch.

[0013] A further improvement of the technical solution of the utility model is that a plurality of slide grooves are symmetrically provided in the inner cavity of the connecting shell.

[0014] The above technical solution is adopted, in which a plurality of slide grooves 1 are opened in the inner cavity of the connecting shell, so that the moving track of the tooth plate can be limited by the cooperation of the slide grooves 1 and the slider, thereby preventing the tooth plate from deviating from the track during movement.

[0015] A further improvement of the technical solution of the utility model is that the driving structure includes two tooth plates, one of which is fixedly connected to a side of a splint close to the tooth plate, and the other is fixedly connected to a connecting block on a side close to the splint, and the connecting block is fixedly connected to a side of the splint close to the tooth plate on the same side, and the opposite surfaces of the two tooth plates are meshed with gears, and the upper end of the tooth plate and the lower end of the tooth plate are fixedly connected to a slider.

[0016] The above technical solution is adopted, in which the tooth plate is fixedly connected to the clamping plate, the tooth plate on the other side is fixedly connected to the connecting block, and the connecting block is connected to the clamping plate on the same side, so that when the two tooth plates move, the two clamping plates can be driven to move toward the opposite surfaces, so that the mold can be clamped by the two clamping plates.

[0017] A further improvement of the technical solution of the utility model is that the gear on the same side is rotatably connected to the inner cavity of the connecting shell, and the output end of the motor on the same side is fixedly connected to the gear.

[0018] The above technical solution is adopted, in which the gear is driven to rotate by the output end of the motor, so that the gear can be used to mesh two adjacent tooth plates, thereby driving the two tooth plates to move.

[0019] A further improvement of the technical solution of the utility model is that the sliding block is T-shaped and is slidably connected with an inner cavity of an adjacent sliding groove.

[0020] The above technical solution is adopted. The T-shaped slider design in this solution increases its contact area with the inner cavity of the slide groove, thereby improving stability. The sliding connection enables the slider to be easily moved when needed and to be precisely adjusted according to production requirements. This flexibility enables the device to adapt to molds of different sizes and specifications, thereby improving production efficiency and product quality.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a mold fixing device for a press machine. The connecting plate can be raised and lowered in the inner cavity of a receiving groove by driving the piston rod of a hydraulic cylinder. This driving method ensures the stability and accuracy of the lifting, so that the height position of the mold can be accurately controlled. At the same time, the connection between the connecting plate and the mold ensures the synchronization of the mold with the lifting of the connecting plate, further improving the accuracy and reliability of the adjustment. Then, the device can clamp molds at different heights as needed, thereby improving the practicability and universality of the device.

[0023] 2. The utility model provides a mold fixing device for a press machine, which drives a driving structure to operate through a motor, thereby using the driving structure to drive a clamping plate to move, and then using the cooperation of two clamping plates to clamp molds of different sizes, thereby preventing the mold from tipping over or moving out of position when the mold is pressure-formed by a support frame, thereby affecting the quality and safety of the product.
