Description

Technical Field

[0001] This utility model belongs to the field of foaming mold technology, and in particular relates to a high-performance composite material foaming mold with venting grooves. Background Technology

[0002] In the prior art, a search revealed a Chinese patent entitled "A Foaming Mold with an Exhaust Component," with publication number "CN214395106U." This patent mainly benefits from the use of an exhaust component. The small aperture of the exhaust screen on its surface can appropriately slow down the gas discharge rate from the chamber, preventing excessive exhaust caused by a large amount of gas overflow. The sliding fit between the mounting ring and the inner wall of the first exhaust hole makes the exhaust component easy to disassemble and clean after long-term use. At the same time, the exhaust screen is detachably set in the ring groove, making it easy to replace exhaust screens with different aperture sizes as needed, thus expanding the applicability of the foaming mold. As needed, a flip cover can be used to close some exhaust holes, thereby reducing the occurrence of large bubbles caused by the accumulation of residual bubbles due to excessive exhaust holes.

[0003] However, this device has a relatively simple structure and uses different aperture venting screens to adjust the gas discharge speed in the chamber. This method requires the operator to replace the venting screen after the mold production is completed, making it difficult to adjust the venting in real time during the die casting process. This may result in the phenomenon that the low venting efficiency leads to the accumulation of bubbles, affecting product quality. Utility Model Content

[0004] The purpose of this invention is to provide a high-performance composite material foaming mold with an exhaust groove. By setting an exhaust mechanism, the operator can rotate the first gear to drive the air intake ring to rotate, adjust the docking contact between the air intake hole and the exhaust groove, and the connection between the air delivery hole and the spiral air delivery pipe. This solves the problem of difficulty in real-time exhaust adjustment during die casting production.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5As shown, this utility model is a high-performance composite material foaming mold with an exhaust groove, including a lower mold 1, on which an exhaust mechanism 2 and a mold mechanism 3 are provided;

[0028] The exhaust mechanism 2 includes a rotating component, a venting component, and an exhaust component. The rotating component includes a connecting groove 21 formed on the front side of the lower mold 1. A rotating shaft 22 is rotatably connected to the inner wall of the connecting groove 21. A first gear 23 is fixedly connected to the outer wall of the rotating shaft 22. A second gear 24 is rotatably connected to the inner wall of the connecting groove 21. The first gear 23 and the second gear 24 mesh. Several connecting blocks 25 are fixedly connected to the top surface of the second gear 24. The venting component includes an air intake ring 26 fixedly connected to the top of the several connecting blocks 25. The outer wall of the air intake ring 26 is provided with several air supply holes 27 and several air intake holes 28. The top surface of the lower mold 1 is provided with an upper mold 29. The bottom surface of the upper mold 29 is provided with several exhaust grooves 210. The outer wall of the air intake ring 26 is rotatably connected to the inner wall of the lower mold 1. The outer walls of several connecting blocks 25 are slidably connected to the inner wall of the lower mold 1. The exhaust assembly includes several spiral air supply pipes 211 fixedly connected to the inner wall of the upper mold 29. The top surface of the lower mold 1 is provided with several exhaust holes 212.

[0029] By setting up the exhaust mechanism 2, the operator can rotate the first gear 23 to drive the air intake ring 26 to rotate, adjust the docking contact between the air intake hole 28 and the exhaust groove 210, and connect the air delivery hole 27 and the spiral air delivery pipe 211. This allows the operator to selectively adjust and discharge excess gas in the cavity 37 in real time without stopping the molding production of the foaming material. The spiral air delivery pipe 211 also slows down the exhaust rate, enhancing the practicality of the device.

[0030] The mold mechanism 3 includes a limiting component and a mold assembly. The limiting component includes several slots 31 opened on the sides of the lower mold 1 and the upper mold 29 that are close to each other. The inner walls of the slots 31 are slidably connected to the blocks 32. The sides of the blocks 32 that are far apart from each other are fixedly connected to the upper mold 29 and the lower mold 1. The top surface of the lower mold 1 has several grooves 33. The inner walls of the grooves 33 are fixedly connected to the limiting posts 34. The bottom surface of the upper mold 29 is fixedly connected to several connecting blocks 25. The bottom surface of the upper mold 29 has several sliding grooves 36. The outer walls of the limiting posts 34 are slidably connected to the inner walls of the sliding grooves 36. The mold assembly includes a cavity 37 opened on the bottom surface of the upper mold 29. The top surface of the lower mold 1 is fixedly connected to the core block 38. The top surface of the upper mold 29 is fixedly connected to the sprue pipe 39.

[0031] By setting up the mold mechanism 3, several slots 31 are used to interlock with the blocks 32, and the lifting and limiting of the limit post 34 and the slide 36 are coordinated to ensure that the lower mold 1 and the upper mold 29 fit tightly together. At the same time, it reduces the possibility of external gas entering the cavity 37 and the core block 38 through the contact surface of the lower mold 1 and the upper mold 29, which may affect the shaping of the foaming material, and further improves the practicality of the device.

[0032] A specific application of this embodiment is as follows: By setting the exhaust mechanism 2, after the lower mold 1 rises and drives the core block 38 to press against the cavity 37 of the upper mold 29, and after the die casting operation is performed, when an exhaust operation is required, the first gear 23 can be rotated. Since the first gear 23 meshes with the second gear 24, the first gear 23 drives the second gear 24 to rotate. The second gear 24 drives the air intake ring 26 to rotate through the connection of several connecting blocks 25, aligning several air intake holes 28 with the exhaust groove 210. At this time, the personnel pour the foaming material into the cavity 37 through the sprue pipe 39. The excess gas in the cavity 37 enters the air intake ring 26 through the exhaust groove 210 and the air intake holes 28, and is transported into the spiral air supply pipe 211 through the air supply hole 27, and then spirally transported through the exhaust hole from the spiral air supply pipe 211. The gas is discharged through a spiral pipe 211. This spiral design mitigates the risk of burns from direct high-temperature gas discharge compared to direct discharge, which could result in burns from high-speed gas contact with the human body. The spiral discharge slows down the rate of direct gas discharge. Simultaneously, the rotating first gear 23 causes the air inlet 28 on the air inlet ring 26 to misalign with the exhaust groove 210, allowing the high-temperature gas to circulate within the air inlet ring 26 and further slowing the exhaust rate. This allows workers to rotate the first gear 23 to rotate the air inlet ring 26, adjusting the contact between the air inlet 28 and the exhaust groove 210, as well as the connection between the gas outlet 27 and the spiral pipe 211. This eliminates the need to terminate the foaming material molding process, facilitating real-time selective adjustment and discharge of excess gas within the cavity 37. The spiral delivery of the gas through the spiral pipe 211 further enhances the device's practicality.

[0033] By setting up mold mechanism 3, the operator can drive the lower mold 1 to align several limiting posts 34 with the slide groove 36, and push the lower mold 1 up to slide the washer 35 into the groove 33. This ensures that the limiting posts 34 limit the upper mold 29 while simultaneously contacting the limiting posts 34 with the slide groove 36 for buffer sealing. It also drives the two locking blocks 32 and the locking groove 31 on the lower mold 1 to align with the locking groove 31 and the locking block 32 on the upper mold 29 for further limiting, making the lower mold 1 and the upper mold 29 fit tightly together. This pushes the core block 38 into the cavity 37, and the foaming material is then introduced through the sprue pipe 39. The material is poured into the cavity 37 for molding, and the gas and bubbles formed in the cavity 37 are discharged through the exhaust groove 210. With the adjustment of the exhaust mechanism 2, the influence of excess gas on the shaping of the foam material is reduced. The device uses several slots 31 to interlock with the blocks 32, and with the lifting and limiting of the limit post 34 and the slide groove 36, it ensures that the lower mold 1 and the upper mold 29 fit tightly, while reducing the possibility of external gas entering the cavity 37 and the core block 38 through the contact surface of the lower mold 1 and the upper mold 29 and affecting the shaping of the foam material. This further improves the practicality of the device.
