Description

Technical Field

[0001] This utility model relates to the field of relief semi-mold technology, specifically a pneumatically formed relief semi-mold stamping structure. Background Technology

[0002] The air pressure forming relief semi-mold stamping structure is based on the air pressure forming principle. It is a structure with specific design in mold design and stamping process, used to manufacture products with relief effect. It usually consists of a pair of upper and lower molds, pressure plate, frame, air intake device, etc.

[0003] First, the plastic sheet is preheated, then it is quickly pressed together by a pressure plate and frame. Next, compressed air is introduced through the air intake device to pre-form the sheet and make the forming depth exceed the height of the male mold. Then, the male mold is lifted from below the pre-formed sheet by a plunger. After the sheet cools down, it tightly wraps around the relief surface of the male mold to form a product with a relief effect.

[0004] During long-term stamping, the cutting edge of the die will gradually wear down due to continuous friction with the sheet metal. When the cutting edge wears down, its sharpness decreases, and it cannot cleanly cut the material when stamping the sheet metal. Instead, some tiny metal particles will be torn off, forming metal shavings. Metal shavings are generated during the stamping process. In continuous stamping operations, a certain amount of shavings will be generated every hour. If they are not cleaned in time, the metal shavings and other foreign objects generated during processing will adhere to the surface of the upper die. During stamping, these foreign objects will form a friction medium between the sheet metal and the upper die, thereby scratching the surface of the product and affecting the product quality.

[0005] Therefore, a pneumatically formed relief semi-mold stamping structure is proposed to address the above problems. Utility Model Content

[0027] Please see Figure 1-6 This utility model provides a technical solution:

[0028] A pneumatically formed relief semi-mold stamping structure includes a power control device 1, an upper mold base 3 for mounting the upper mold, and a lower mold base 4 for mounting the lower mold. Cleaning devices 5 are fixedly connected to both sides of the power control device 1. The cleaning device 5 includes a support frame 51 with a sliding groove 52 on its inner side. Electric telescopic rods 53 are fixedly connected to both sides of the support frame 51. One end of the electric telescopic rod 53 passes through the support frame 51 and is fixedly connected to a cleaning plate 54 on one side. A slider 55 is fixedly connected to one end of the cleaning plate 54, and the slider 55 slides slidably with the upper and lower sides of the sliding groove 52. The cleaning plate 54 includes a mounting plate 541 with a mounting groove 542 at its upper end. A mounting pin 544 is installed inside the mounting groove 542. A magnetic suction plate 543 is fixedly connected to the other end of the mounting pin 544. An elastic element 545 is fixedly connected to the inner side of the magnetic suction plate 543. A sliding plate 546 is fixedly connected to the upper end of the elastic element 545, and a cleaning scraper 547 is fixedly connected to the upper end of the sliding plate 546.

[0029] As a further implementation of the above technical solution: two electric telescopic rods 53 and two cleaning plates 54 are provided. The electric telescopic rods 53 and two cleaning plates 54 are symmetrically arranged on both sides of the support frame 51 with the center line of the slide groove 52 as the axis. One end of the electric telescopic rod 53 is perpendicular to one side of the cleaning plate 54. Through telescopic movement, the cleaning plate 54 is pushed to move along the slide groove 52, so as to realize the contact and separation between the cleaning plate 54 and the surface of the upper mold. Its precise telescopic control can ensure that the pressure of the cleaning scraper 547 adhering to the surface of the upper mold is moderate, which can effectively clean foreign objects without damaging the upper mold.

[0030] As a further implementation of the above technical solution: the sliding plate 546 is slidably connected to the inner side of the magnetic suction plate 543, the elastic element 545 is disposed between the inner side of the magnetic suction plate 543 and the bottom of the sliding plate 546, the cleaning scraper 547 is triangular in shape in vertical section, the upper end of the cleaning scraper 547 is in close contact with the bottom of the upper mold of the upper mold base 3, and under the action of the elastic element 545, it can slide inside the magnetic suction plate 543, driving the cleaning scraper 547 to move up and down, ensuring that the cleaning scraper 547 always maintains a good contact state with the surface of the upper mold, and can effectively scrape off the metal debris and other foreign objects attached to the surface of the upper mold, ensuring the cleanliness of the surface of the upper mold;

[0031] As a further implementation of the above technical solution: a stamping actuator 2 is fixedly connected to one side of the power control device 1, an upper mold base 3 is fixedly connected to the lower end of the stamping actuator 2, and a lower mold base 4 is fixedly connected to one side of the power control device 1, so as to ensure the relative position accuracy of the upper mold and the lower mold during the stamping process, and provide a stable mold installation and working platform for the relief forming of the sheet metal.

[0032] As a further implementation of the above technical solution: the support frame 51 is U-shaped and is located between the upper mold base 3 and the lower mold base 4. The two ends of the support frame 51 are fixedly connected to the outside of the power control device 1 by bolts. The length of the slide groove 52 is equal to the length of the side away from the bolts, which serves to support and fix the electric telescopic rod 53, cleaning plate 54 and other components, ensuring the overall structural stability of the cleaning device 5. The slide groove 52 provides guidance and support for the movement of the cleaning plate 54, so that the cleaning plate 54 can smoothly approach or move away from the upper mold of the upper mold base 3 along a fixed trajectory.

[0033] As a further implementation of the above technical solution: the mounting plate 541 has two mounting holes on its inner side, which correspond to the mounting pins 544. The mounting holes on the inner side of the mounting plate 541 and the mounting pins 544 are in clearance fit. The mounting holes on the inner side of the mounting plate 541 are connected to the mounting groove 542. As the basic structure of the cleaning plate 54, it provides a platform for installing components such as the magnetic plate 543. The clearance fit between the mounting holes on its inner side and the mounting pins 544 facilitates the installation and disassembly of components such as the magnetic plate 543, and makes it easy to disassemble and clean the cleaning components.

[0034] As a further implementation of the above technical solution: two sliders 55 are provided. The sliders 55 pass through the support frame 51 and are slidably connected to the inside of the slide groove 52. The sliders 55 are parallel to each other. The sliders 55 are rectangular in shape. They play a guiding and supporting role in the movement of the cleaning plate 54, ensuring the stability and accuracy of the movement of the cleaning plate 54, so that the cleaning scraper 547 can accurately reach the surface of the upper mold for cleaning.

[0035] Workflow: The entire equipment is powered by an external wire. The sheet material to be processed is placed on the lower die of the lower die base 4 to ensure accurate positioning. The power control device 1 is activated to provide power support for the entire system. The power control device 1 controls the stamping actuator 2 to move downward, which drives the upper die of the upper die base 3 to move downward until the upper die contacts the sheet material on the lower die base 4. Under air pressure, the upper die applies pressure to the sheet material, causing the sheet material to undergo plastic deformation between the upper and lower dies, thus completing the relief forming. After stamping is completed, the power control device 1 controls the stamping actuator 2 to drive the upper die of the upper die holder 3 to return to the initial position. After the stamping actuator 2 drives the upper die of the upper die holder 3 to the initial position, the power control device 1 issues a command to start the cleaning device 5. At this time, the electric telescopic rod 53 is in the initial retracted state, and the cleaning plate 54 is located away from the upper die of the upper die holder 3. The power control device 1 controls the electric telescopic rod 53 to start extending. The electric telescopic rod 53 pushes the cleaning plate 54 to move along the slide groove 52 on the inner side of the support frame 51 towards the upper die of the upper die holder 3. Since the slider 55 is slidably connected to the slide groove 52, the cleaning plate 54 can move smoothly. As the electric telescopic rod 53 continues to extend, the cleaning scraper 547 of the cleaning plate 54 gradually approaches the bottom of the upper die of the upper die holder 3 until the cleaning scraper 547 is in close contact with the surface of the upper die. At this time, the elastic element 545 is in a compressed state, providing a certain pressure to the cleaning scraper 547 so that it can better fit. After the cleaning scraper 547 contacts the upper mold surface, the electric telescopic rod 53 drives the cleaning plate 54 to reciprocate linearly along the slide groove 52. During the movement, the cleaning scraper 547 scrapes away metal debris and other foreign objects attached to the upper mold surface. At the same time, the magnetic plate 543 uses its own magnetism to attract the scraped metal debris, preventing it from falling or flying again, avoiding secondary pollution to the mold and the product, and improving the cleaning effect. The elastic element 545 provides elastic pressure to the sliding plate 546 and the cleaning scraper 547, so that the cleaning scraper 547 can better fit the upper mold surface and adapt to the slight undulations that may exist on the upper mold surface, improving the thoroughness of cleaning. After cleaning is completed by multiple reciprocating movements, the power control device 1 controls the electric telescopic rod 53 to retract, driving the cleaning plate 54 to move along the slide groove 52 away from the upper mold base 3 until the cleaning plate 54 returns to the initial position. At this point, the cleaning device 5 has completed the cleaning work on the upper mold surface of the upper mold base 3 and is ready for the next cleaning.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
