Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a quick-change mechanism for hot-press mold cover plates. Background Technology

[0002] Hot press mold cover plates are an important component in the hot press molding process and are widely used in industries such as electronics, automobiles, and aerospace. Especially in the manufacturing process of composite materials, hot press mold cover plates are usually made of high-strength, high-temperature resistant materials and are used to cover the molded parts during the hot press process to ensure uniform distribution of heating and pressure. The cover plate can not only effectively prevent damage to the mold surface, but also ensure the surface quality of the molded parts and prevent defects such as bubbles or uneven surfaces.

[0003] In existing technologies, hot press mold cover plates are usually tightly fitted with the lower mold to form a sealed state, ensuring uniform distribution of heating and pressure during the hot pressing process. However, due to the large weight of the hot press mold cover plates, especially those made of metal, replacement often presents operational difficulties when damaged. The weight of the mold cover plates makes replacement work cumbersome and time-consuming, requiring operators to use large lifting equipment or multiple workers to complete the replacement process, increasing labor intensity and operational difficulty. Utility Model Content

[0004] Technical problems to be solved

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a quick replacement mechanism for hot press mold cover plates. By using replacement components, the upper mold can be replaced quickly, thereby improving replacement efficiency and avoiding the situation of continued use after damage.

[0006] Technical solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a quick replacement mechanism for a hot press mold cover plate, comprising a support frame body and a lower mold, an upper mold being provided at the top of the lower mold, a top plate being fixedly connected at the center of the top of the support frame body, a replacement component for driving the upper mold to be replaced being provided at the bottom of the top plate, and an auxiliary mechanism cooperating with the replacement component being provided at the bottom of the top plate.

[0008] Preferably, the upper top of the upper mold is fixedly connected to two symmetrical first T-shaped support frames, and the upper top of the upper mold is fixedly connected to two symmetrical hanging rings, with the two hanging rings located between the first T-shaped support frames.

[0009] Preferably, the inner wall of the support frame body is fixedly connected to two symmetrical second T-shaped support frames. The outer wall of the second T-shaped support frame is slidably sleeved with a limiting frame that cooperates with the first T-shaped support frame. The first T-shaped support frame and the limiting frame are slidably sleeved. The outer walls of the first T-shaped support frame and the limiting frame are provided with several through holes. The outer wall of the limiting frame is inserted with a positioning pin inside the through hole.

[0010] Preferably, the replacement component includes a drive motor fixedly connected to the bottom of the top plate, a drive rod fixedly connected to the output end of the drive motor, mounting brackets symmetrically fixedly connected to the outer wall of the drive motor, and the end of the mounting brackets fixedly connected to the bottom of the top plate, a spline groove opened on the outer wall of the drive rod, and bearing brackets symmetrically fixedly connected to the bottom of the top plate, and the bearing brackets are rotatably sleeved with the end of the drive rod, and the bearing brackets and the drive rod are rotatably sleeved through bearings.

[0011] Preferably, a cable take-up frame is rotatably sleeved on the outer wall of the drive rod, and a cable is wound around the outer wall of the cable take-up frame. A hook is fixedly connected to the end of the cable, and the hook is sleeved inside the hanging ring.

[0012] Preferably, the auxiliary mechanism includes a first chuck fixedly connected to the side of the cable take-up frame near the drive motor, and the first chuck is rotatably sleeved with the drive rod.

[0014] Compared with existing technologies, this quick-change mechanism for hot-pressed mold cover plates has the following advantages:

[0015] I. This utility model replaces components and uses a hook and a hanging ring above the upper mold to cooperate with each other. Then, the drive motor drives the drive rod to rotate. With the assistance of the auxiliary mechanism, the cable take-up frame can rotate. The cable take-up frame drives the cable and the hook to retract. At this time, the hook drives the upper mold to rise, and the upper mold separates from the lower mold.

[0016] Second, move the first T-shaped support frame to the same height below the limiting frame. The limiting frame can slide on the outer wall of the second T-shaped support frame.

[0024] 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.

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a quick replacement mechanism for a hot press mold cover plate, including a support frame body 1 and a lower mold 5. An upper mold 6 is provided at the top of the lower mold 5. A top plate 2 is fixedly connected at the center of the top of the support frame body 1. A replacement component 3 for driving the upper mold 6 to be replaced is provided at the bottom of the top plate 2. An auxiliary mechanism 4 that cooperates with the replacement component 3 is provided at the bottom of the top plate 2.

[0026] It should be noted that the main support frame 1, as the overall frame, firmly supports the structure of the entire system, enabling each component to cooperate reliably and ensuring stability and safety during the replacement process. The cooperation between the upper mold 6 set at the top of the lower mold 5 and the replacement component 3 makes the replacement of the mold cover plate faster and more accurate. The replacement component 3 can not only quickly complete the replacement of the mold cover plate, but also ensure that the position of the mold cover plate after each replacement is accurate, reducing human error and ensuring consistency and stability during the hot pressing process.

[0027] like Figures 1-5 As shown, the upper top of the upper mold 6 is fixedly connected to two symmetrical first T-shaped support frames 61, and the upper top of the upper mold 6 is fixedly connected to two symmetrical hanging rings 62, with the two hanging rings 62 located between the first T-shaped support frames 61.

[0028] It should be noted that the two symmetrical first T-shaped support frames 61 fixedly connected to the top of the upper mold 6 enhance the stability and support capacity of the upper mold 6 through structural design. The hanging ring 62 provides a reliable fixing point for connection and disassembly, making the replacement of the hot press mold cover plate safer and more efficient.

[0029] like Figure 2 and Figure 4 As shown, two symmetrical second T-shaped support frames 7 are fixedly connected to the inner side wall of the support frame body 1. The outer wall of the second T-shaped support frame 7 is slidably sleeved with a limiting frame 8 that cooperates with the first T-shaped support frame 61. The first T-shaped support frame 61 and the limiting frame 8 are slidably sleeved. The outer walls of the first T-shaped support frame 61 and the limiting frame 8 are provided with several through holes 63. The outer wall of the limiting frame 8 is inserted with a positioning pin 9 inside the through hole 63.

[0030] It should be noted that the second T-shaped support frame 7 is symmetrically arranged along the inner side wall of the support frame body 1, providing a stable sliding track for the limiting frame 8, and forming a double-T nested structure with the first T-shaped support frame 61 on the top of the upper mold 6. When the upper mold 6 is raised to the limiting height, the limiting frame 8 only needs to be horizontally moved to allow it to be inserted into the first T-shaped support frame 61 without obstruction. The through holes 63 are distributed in an equidistant array on the first T-shaped support frame 61 and the limiting frame 8. By inserting the positioning pin 9 into different hole combinations, the positioning of the upper mold 6 can be achieved.

[0031] like Figure 2 and Figure 3As shown, the replacement component 3 includes a drive motor 31 fixedly connected to the bottom of the top plate 2. A drive rod 32 is fixedly connected to the output end of the drive motor 31. A mounting bracket 311 is symmetrically fixedly connected to the outer wall of the drive motor 31, and the end of the mounting bracket 311 is fixedly connected to the bottom of the top plate 2. A spline groove 33 is provided on the outer wall of the drive rod 32. A bearing bracket 341 is symmetrically fixedly connected to the bottom of the top plate 2, and the bearing bracket 341 is rotatably sleeved with the end of the drive rod 32. The bearing bracket and the drive rod are rotatably sleeved through the bearing. A cable take-up bracket 34 is rotatably sleeved on the outer wall of the drive rod 32. A cable 35 is wound around the outer wall of the cable take-up bracket 34. A hook 36 is fixedly connected to the end of the cable 35, and the hook 36 is sleeved inside the hanging ring 62.

[0032] It should be noted that the spline groove 33 on the outer wall of the drive rod 32 engages with the key teeth on the inner wall of the cable take-up frame 34, so that the torque of the drive motor 31 is transmitted to the cable take-up frame 34. The end of the drive rod 32 is supported at both ends by the bearing frame 341, which reduces the vibration amplitude of the equipment when the cable 35 is being taken up and put down at high speed.

[0033] like Figure 2 and Figure 3 As shown, the auxiliary mechanism 4 includes a first chuck 41 fixedly connected to the side of the cable take-up frame 34 near the drive motor 31, and the first chuck 41 is rotatably sleeved with the drive rod 32. The outer wall of the drive rod 32 is slidably sleeved with a second chuck 42 at the position of the spline groove 33. The side of the second chuck 42 near the drive motor 31 is fixedly connected with a limit sleeve 43. The side of the mounting frame 311 near the cable 35 is fixedly connected with an electric push rod 44. The telescopic end of the electric push rod 44 is fixedly connected with a horizontal push frame 45. The horizontal push frame 45 is rotatably sleeved on the outer wall of the limit sleeve 43.

[0034] It should be noted that the first chuck 41 is rotatably sleeved with the drive rod 32, ensuring smooth and efficient transmission. The second chuck 42 is slidably sleeved on the outer wall of the drive rod 32, and the spline groove 33 at its position can provide greater friction, increasing the stability of the chuck, thereby ensuring the reliability of the entire system under high load. When the transverse push frame 45 is rotatably sleeved on the outer wall of the limit sleeve 43, the thrust can be evenly distributed by controlling the electric push rod 44, reducing the imbalance in the system operation.

[0035] Working principle: When changing the upper mold 6, the upper mold 6 and the lower mold 5 are separated first by the replacement component 3. The hook 36 in the replacement component 3 is pre-fitted into the two symmetrically arranged hanging rings 62 at the top of the upper mold 6. Then, the drive motor 31 is started. The drive motor 31 rotates through the drive rod 32 fixedly connected to the output end. The spline groove 33 on the outer wall of the drive rod 32 slides and engages with the second chuck 42 in the auxiliary mechanism 4. With the cooperation of the auxiliary mechanism 4, the drive rod 32 drives the cable take-up frame 34 to rotate synchronously. The cable 35 wrapped on the outer wall of the cable take-up frame 34 retracts accordingly, thereby driving the hook 36 to lift upward, so that the upper mold 6 and the lower mold 5 are completely separated.

[0036] After the upper mold 6 is raised to a certain height, the operator moves the two symmetrically arranged first T-shaped support frames 61 at the top of the upper mold 6 to the same height below the limiting frame 8 which is slidably sleeved with the outer wall of the two symmetrically arranged second T-shaped support frames 7 on the inner side wall of the support frame body 1. At this time, by sliding the limiting frame 8, it is made to cooperate with the first T-shaped support frame 61, and the positioning pin 9 is inserted into the through hole 63 opened on the outer wall of both to achieve precise limiting of the upper mold 6. After the limiting is completed, the operator separates the hook 36 from the hanging ring 62. At this time, the upper mold 6 is completely supported by the limiting 8. Then the upper mold 6 can be moved to one side along the second T-shaped support frame 7 to complete the quick disassembly of the upper mold 6.

[0037] The hook 36 is re-sleeved inside the hanging ring 62 of the new upper mold 6, and the drive motor 31 rotates in the opposite direction. Through the contraction action of the cable 35 and the hook 36, the new upper mold 6 is slowly lowered above the lower mold 5, completing the installation of the upper mold 6. When the drive motor 31 starts, the first chuck 41, which is fixedly connected to the cable take-up frame 34 on the side near the drive motor 31, rotates and engages with the drive rod 32. At the same time, the telescopic end of the electric push rod 44 pushes the limiting sleeve 43 through the horizontal push frame 45, thereby driving the second chuck 42 to slide along the spline groove 33, ensuring that the cable take-up frame 34 and the drive rod 32 rotate synchronously, thereby achieving stable contraction and release of the cable 35. In addition, the rotating engagement design of the electric push rod 44 with the horizontal push frame 45 and the limiting sleeve 43 can maintain the stability of the horizontal push frame 45 when the drive rod 32 rotates, avoiding the torque generated by the rotation from affecting the axial movement of the limiting sleeve 43.
