Description

Technical Field

[0001] This utility model relates to the field of molding die technology, specifically to an automatic demolding high-pressure molding die. Background Technology

[0002] High-pressure forming dies are key tooling equipment used in high-pressure forming processes. They are widely used in many industries such as automotive, electronics, and aerospace to manufacture various complex-shaped parts with high dimensional accuracy requirements. The production of products such as car bumpers, electronic device housings, and aero-engine blades cannot be separated from high-pressure forming dies.

[0003] In the prior art, Chinese Patent Publication No. CN222061133U discloses a high-pressure molding die for a battery casing, including an upper die and a lower die. An upper support arm is fixed to the outside of the upper die, and a lower support arm is fixed below the upper support arm of the lower die. A detection unit is provided on the lower support arm, and a detection end is fixed on the upper support arm. The detection end moves down with the upper die to fit against the lower die and performs displacement detection with the detection unit. Through the cooperation of the detection end and the detection unit, the accuracy of the mold closing can be accurately detected during the relative mold closing movement of the upper and lower dies. If a positional deviation occurs during mold closing, an audible and visual alarm can provide timely feedback and alarm, which is beneficial to the protection of the mold itself and the quality assurance of the injection molded product itself.

[0004] Based on the above information, it can be seen that in existing high-pressure molding, the product is often tightly fitted inside the mold cavity, making demolding difficult. This not only results in low efficiency but also easily causes scratches, deformation, and other damage to the product surface, affecting product quality. Therefore, we propose an automatic demolding high-pressure molding mold. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic demolding high-pressure forming mold to solve the problem mentioned in the background art that after high-pressure forming, the product is often tightly attached to the inside of the mold cavity, making demolding difficult. This not only results in low efficiency but also easily causes scratches, deformation and other damage to the product surface, affecting product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic demolding high-pressure molding die, comprising a die body, a die core detachably mounted on the outer wall of the die body, a demolding mechanism for automatically demolding the product on the outer wall of the die core, the demolding mechanism including an ejector air chamber disposed inside the die body, an air inlet pipe fixedly mounted on the outer wall of the die body, and an electromagnetic valve disposed on the outer wall of the air inlet pipe, an air hole opened on the outer wall of the die core, an ejector block slidably mounted on the inner wall of the air hole, and a slider slidably connected to the die core fixedly mounted on the outer wall of the ejector block, a through groove opened on the outer wall of the ejector block, and a replacement mechanism for disassembling and cleaning the die core on the outer wall of the die body.

[0007] Furthermore, the ejection air chamber is provided correspondingly to the mold core, and the air holes are provided at equal intervals on the outer wall of the mold core and inside the mold body, and the air holes penetrate the outer wall of the mold core, and the ends of the air holes are connected to the inside of the ejection air chamber.

[0008] Furthermore, one end of the air inlet pipe is connected to the exhaust air chamber, and the other end of the air inlet pipe is connected to an air pump.

[0009] Furthermore, the ejector block is cylindrical in shape, and the outer diameter of the ejector block corresponds to the outer diameter of the air hole. The top outer wall of the ejector block is on the same horizontal plane as the outer wall of the mold core. The through groove penetrates the outer wall of the ejector block, and the length of the through groove is less than the length of the ejector block.

[0010] Furthermore, the slider is set at an equal angle on the outer wall of the ejector block, and a groove corresponding to the slider is opened inside the mold body, and the length of the groove is set to correspond to the sliding range of the ejector block.

[0011] Furthermore, the replacement mechanism includes a fixing block slidably installed inside the mold body, and a fixing bolt threadedly connected to the mold body is rotatably installed at the end of the fixing block, and a handle is fixedly installed at the end of the fixing bolt. The outer wall of the mold core has a fixing groove corresponding to the fixing block, the inner wall of the mold body has an adjustment groove corresponding to the fixing block, and a limiting block is provided on the inner wall of the adjustment groove. The outer wall of the fixing block has a limiting groove corresponding to the limiting block. A sealing gasket is provided between the mold core and the mold body.

[0012] Furthermore, the fixed block has a trapezoidal cross-section, and the outer wall of the fixed block close to the mold core has an inclined surface design. The length of the fixing bolt is set to correspond to the sliding range of the fixed block.

[0013] Furthermore, two sets of limiting blocks are symmetrically arranged on the inner wall of the adjusting groove, and the outer wall of the limiting block is in contact with the outer wall of the fixing block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This automatic demolding high-pressure forming mold, equipped with a demolding mechanism, greatly improves demolding efficiency and ensures product quality. After the product completes high-pressure forming, the solenoid valve is activated, and the air pump delivers high-pressure gas to the ejector air chamber through the air inlet pipe. Since the ejector air chamber is connected to the air hole on the mold core, the high-pressure gas quickly enters the air hole, pushing the ejector block to slide outward along the air hole. The top of the ejector block contacts the product, and during its outward sliding process, it can evenly lift the product from the mold core, achieving automatic demolding. This avoids the operation that may cause scratches or deformation to the product during demolding. At the same time, the ejector block is cylindrical and its outer diameter matches the outer diameter of the air hole. The top is on the same horizontal plane as the outer wall of the mold core, so it will not affect the product forming effect during high-pressure forming. The through groove ensures that the gas can smoothly act on the ejector block and push it to move. In addition, the slider on the outer wall of the ejector block cooperates with the sliding groove in the mold body to ensure the stability of the ejector block's sliding, making the demolding process more reliable and efficient, and significantly improving production efficiency and product yield.

[0016] 2. The addition of a replacement mechanism greatly facilitates mold maintenance and cleaning. When the mold core needs to be disassembled for cleaning or replacement, rotating the handle causes the fixing bolt to rotate. Since the fixing bolt is threadedly connected to the mold body, it gradually moves away from the mold core during rotation, causing the fixing block to slide within the adjustment groove. The fixing block has a trapezoidal cross-section with an inclined surface on the side closest to the mold core. As it slides outward, the inclined surface allows the fixing block to easily disengage from the fixing groove on the outer wall of the mold core, releasing the mold core from its fixation. At this point, the mold core can be easily removed from the mold body for cleaning or replacement. Installing the mold core is done in reverse. The limiting block in the adjustment groove cooperates with the limiting groove on the outer wall of the fixing block, limiting the sliding range of the fixing block and ensuring its stability during operation, preventing accidental disengagement. Furthermore, the sealing gasket between the mold core and the mold body ensures the mold's sealing performance during high-pressure molding, improving the mold's working performance and service life, reducing production downtime caused by inconvenient mold maintenance, and enhancing overall production efficiency.

[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] Example 1: Please refer to Figure 1-8This utility model provides the following technical solution: an automatic demolding high-pressure molding die, comprising a die body 1, a die core 2 detachably mounted on the outer wall of the die body 1, a demolding mechanism for automatically demolding the product on the outer wall of the die core 2, the demolding mechanism including an ejection air chamber 4 disposed inside the die body 1, an air inlet pipe 3 fixedly mounted on the outer wall of the die body 1, and an electromagnetic valve 301 disposed on the outer wall of the air inlet pipe 3, an air hole 401 opened on the outer wall of the die core 2, an ejector block 5 slidably mounted on the inner wall of the air hole 401, and a slider 501 slidably connected to the die core 2 fixedly mounted on the outer wall of the ejector block 5, a through groove 502 opened on the outer wall of the ejector block 5, the ejection air chamber 4 being correspondingly disposed with the die core 2, and the air hole 401 being located on the outer wall of the die core 2 and the die core 2. The main body 1 has evenly spaced air holes 401 that penetrate the outer wall of the mold core 2 and are connected to the inside of the ejector air chamber 4. One end of the air inlet pipe 3 is connected to the ejector air chamber 4 and the other end of the air inlet pipe 3 is connected to an air pump. The ejector block 5 is cylindrical in shape and its outer diameter corresponds to the outer diameter of the air hole 401. The top outer wall of the ejector block 5 is on the same horizontal plane as the outer wall of the mold core 2. The through groove 502 penetrates the outer wall of the ejector block 5 and its length is less than the length of the ejector block 5. The slider 501 is set at an equal angle on the outer wall of the ejector block 5. The mold body 1 has a groove 201 inside that corresponds to the slider 501 and its length corresponds to the sliding range of the ejector block 5.

[0028] After the high-pressure molding process is completed, the entire automatic demolding process is immediately started. First, the solenoid valve 301 receives the opening signal and opens the passage. The high-pressure gas generated by the external air pump quickly flows into the ejection chamber 4 through the air inlet pipe 3. Since the ejection chamber 4 is connected to the air holes 401 evenly distributed on the mold core 2, the high-pressure gas flows rapidly along the air hole 401 channel. Under the strong thrust of the high-pressure gas, the cylindrical ejector block 5, which was originally located inside the air hole 401, begins to slide outward along the inner wall of the air hole 401. The top of the ejector block 5 directly contacts the molded product. As the ejector block 5 continues to move outward, it applies force evenly to the product, gradually pushing the product out of the tightly fitted mold core. 2. The ejector block 5 is smoothly lifted, thus achieving automatic demolding of the product. During this process, the sliders 501, which are distributed at equal angles on the outer wall of the ejector block 5, will slide synchronously in the grooves 201 pre-opened inside the mold body 1. This ensures the stability of the ejector block 5 during movement and avoids situations such as offset or jamming, ensuring a smooth and efficient demolding process. At the same time, the through grooves 502 specially opened on the ejector block 5 further optimize the gas flow path, allowing high-pressure gas to act more effectively on the ejector block 5, enhancing the pushing force, ensuring the smooth completion of the demolding operation, greatly improving demolding efficiency, and also effectively ensuring product quality, avoiding potential damage to the product caused by the ejector during demolding.

[0029] Example 2: Based on Example 1, a replacement mechanism is also disclosed, the specific structure of which is as follows: The outer wall of the mold body 1 is provided with a replacement mechanism for disassembling and cleaning the mold core 2. The replacement mechanism includes a fixing block 602 slidably installed inside the mold body 1, and a fixing bolt 6 threadedly connected to the mold body 1 is rotatably installed at the end of the fixing block 602. A handle 601 is fixedly installed at the end of the fixing bolt 6. A fixing groove 202 corresponding to the fixing block 602 is opened on the outer wall of the mold core 2. A fixing groove 202 corresponding to the fixing block 602 is opened on the inner wall of the mold body 1. The corresponding adjustment groove 102 is provided, and the inner wall of the adjustment groove 102 is provided with a limiting block 101. The outer wall of the fixing block 602 is provided with a limiting groove 603 corresponding to the limiting block 101. A sealing gasket 7 is provided between the mold core 2 and the mold body 1. The cross section of the fixing block 602 is trapezoidal, and the outer wall of the fixing block 602 close to the mold core 2 is inclined. The length of the fixing bolt 6 is set to correspond to the sliding range of the fixing block 602. Two sets of limiting blocks 101 are symmetrically arranged on the inner wall of the adjustment groove 102, and the outer wall of the limiting block 101 is in contact with the outer wall of the fixing block 602.

[0030] When it is necessary to disassemble, clean, or replace the mold core 2 to maintain the good performance of the mold and the quality of the product, the operator first manually rotates the handle 601. The rotation of the handle 601 drives the fixing bolt 6, which is fixedly connected to it, to rotate synchronously. As the fixing bolt 6 rotates, it gradually moves away from the mold core 2 along the thread direction. The movement of the fixing bolt 6 will also drive the fixing block 602, which is rotatably connected to its end, to slide together in the adjustment groove 102 opened inside the mold body 1. When the fixing block 602 slides outward in the adjustment groove 102, the fixing block 602 is smoothly disengaged from the fixing groove 202 on the outer wall of the mold core 2, thereby releasing the fastening restriction on the mold core 2. At this time, the operator can easily remove the mold core 2 from the mold body 1 for subsequent cleaning, maintenance, or replacement of the new mold core 2. When installing the new mold core 2 or reinstalling the cleaned mold core 2 back into the mold body 1, simply reverse the above operation and accurately place the mold core 2 in the corresponding position of the mold body 1 so that the mold core 2... The fixing groove 202 on the upper part is precisely aligned with the fixing block 602. Then, the handle 601 is rotated again, causing the fixing bolt 6 to rotate in the opposite direction. The fixing bolt 6 pushes the fixing block 602 to slide towards the mold core 2 until the fixing block 602 is tightly inserted into the fixing groove 202 of the mold core 2, thus completing the fixed installation of the mold core 2. During the entire process, the limiting blocks 101 symmetrically arranged on the inner wall of the adjusting groove 102 will closely cooperate with the limiting groove 603 opened on the outer wall of the fixing block 602, effectively limiting the sliding range of the fixing block 602, ensuring that the fixing block 602 always maintains a stable state during operation, preventing it from accidentally falling out, thereby ensuring the firmness and stability of the mold core 2 installation. In addition, the sealing gasket 7 specially set between the mold core 2 and the mold body 1 can effectively fill the tiny gaps between the two when the mold is subjected to high pressure molding, ensuring the sealing of the mold interior, greatly improving the working performance and service life of the mold, significantly reducing the production downtime caused by inconvenient mold maintenance, and ultimately improving the overall production efficiency.
