Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to a mold for producing a TV shell. Background Technique

[0002] With the continuous improvement of people's living standards, display devices such as TVs have gradually entered every household. In order to ensure the overall aesthetics of the TV and protect the internal components of the TV, a shell is often installed outside the TV. Nowadays, stamping molds are often used in the production of TV shells. Stamping is a common metal processing method used to process flat metal materials into workpieces of the required shape through stamping mechanical equipment.

[0003] After retrieval, the utility model patent with the publication number of CN217990668U discloses a stamping mold for a TV shell, which generally includes components such as a fixed mold, a movable mold and a spring. By setting a stamping buffer mechanism, the starting cylinder two drives the connecting plate and the buffer plate to move downward. The buffer plate first contacts the fixed mold, thereby squeezing the spring. The movable mold is clamped into the fixed mold to stamp the stamping material. In this way, it can have the advantages of buffering the impact force and improving the stamping quality. However, this patent limits that only the movable mold is moving while the fixed mold remains stationary, which may lead to uneven stress distribution during the stamping process, and the stamping speed and frequency are limited, resulting in low production efficiency and inability to meet the requirements of high-speed production. To solve this problem, the utility model provides a mold for producing a TV shell to overcome the problems of low production efficiency and inability to adapt to high-speed production in the prior art. Summary of the Utility Model

On the upper sides of the four corners of the base 1, sliding rods 2 are fixedly connected. At the upper ends of the sliding rods 2, a fixing plate 3 is fixedly connected. On the upper part of the fixing plate 3, a hydraulic cylinder 4 is fixedly installed. The telescopic rod of the hydraulic cylinder 4 faces downward. The telescopic rod of the hydraulic cylinder 4 is fixedly connected to the upper die machine 5. A lower die machine 6 is arranged on the upper part of the base 1. The upper die machine 5 and the lower die machine 6 can cooperate with each other to complete the stamping and cutting tasks. At the four corners of the lower die machine 6, sliding sleeves 7 are fixedly connected. The sliding sleeves 7 are slidably connected to the sliding rods 2. The sliding sleeves 7 are made of steel, and the steel has high hardness and wear resistance, enabling the sliding sleeves 7 to withstand high-intensity and frequent movements without being easily damaged. At the same time, a lubricating layer is coated on the sliding rods 2, and the lubricating layer can play a buffering and protective role during the sliding process, reducing the wear between the surfaces and delaying the service life of the sliding sleeves 7. On the front and rear sides of the upper die machine 5, upper racks 8 are fixedly connected. On the front and rear sides of the lower die machine 6, lower racks 9 are fixedly connected. On the front and rear parts of the base 1, support seats 10 are fixedly connected. On the upper part of the support seats 10, a gear 11 is rotatably connected. The gear 11 meshes with both the upper rack 8 and the lower rack 9. On the upper part of the support seats 10, a dust-proof box 20 is fixedly connected. The dust-proof box 20 wraps the gear 11, the lower part of the upper rack 8 and the upper part of the lower rack 9. Grooves for the upper rack 8 and the lower rack 9 to move up and down are provided on both the upper and lower sides of the dust-proof box 20. The dust-proof box 20 can effectively prevent external substances such as dust, dirt, and debris from invading and avoid equipment damage. On the front and rear parts of the fixing plate 3, lubricating oil tanks 16 are fixedly connected. The oil-dropping ports of the lubricating oil tanks 16 face the gear 11, and a control valve 17 is provided at the oil-dropping ports of the lubricating oil tanks 16. The control valve 17 can control the flow rate of the lubricating oil. A through hole is provided on the upper side of the dust-proof box 20, and the oil-dropping ports of the lubricating oil tanks 16 are inserted into the through holes, ensuring the accuracy during the oil-dropping process, preventing the lubricating oil from dripping into the external environment, and keeping the working environment clean. At the bottom of the base 1, a mounting frame 12 is fixedly connected. On the upper part of the mounting frame 12, an air pump 13 is fixedly installed. On both the left and right sides of the air pump 13, air pipes 14 are fixedly installed. At the upper parts of the air pipes 14, suction nozzles 15 are fixedly installed. On the front side of the left part of the upper die machine 5, a switch button 18 is fixedly connected. The switch button 18 is used to control the opening and closing of the air pump 13. On the lower side of the left part of the fixing plate 3, a pressing plate 19 is fixedly connected. The pressing plate 19 can press the switch button 18.

[0023] Working principle: Place the flat metal material on the upper part of the lower die machine 6, and then start the hydraulic cylinder 4. The telescopic rod of the hydraulic cylinder 4 drives the upper die machine 5 to move downward. As a result, the upper rack 8 moves downward. The upper rack 8 drives the gear 11 to rotate through meshing transmission. The gear 11 drives the lower rack 9 to move upward through meshing transmission, and then drives the lower die machine 6 to move upward. Then, the upper die machine 5 is clamped into the lower die machine 6 to punch the stamping material. After punching, the upper die machine 5 cuts the stamping material. After cutting the stamping material into the corresponding shape, start the hydraulic cylinder 4 again. The telescopic rod of the hydraulic cylinder 4 drives the upper die machine 5 to move upward. At the same time, the upper rack 8 drives the lower die machine 6 to move downward through meshing transmission. Since the upper die machine 5 moves upward, the lower part of the pressing plate 19 presses the upper part of the switch button 18, and then the air pump 13 is started. The air pump 13 sucks air, and then the suction nozzle 15 sucks the cut waste to prevent the waste from being sucked when the manipulator sucks the finished product. Then, the manipulator sucks away the stamped finished product. The telescopic rod of the hydraulic cylinder 4 drives the upper die machine 5, and then the pressing plate 19 is separated from the switch button 18, and then the air pump 13 is closed. The air pump 13 no longer sucks air. Finally, the waste is taken away manually or by the manipulator to complete the stamping task.
