Description

Technical Field

[0001] The utility model relates to the technical field of automobile motor housing processing, in particular to a mold for processing an automobile motor housing with rapid cooling. Background Technique

[0002] The automobile motor housing is a key component in new energy vehicles, mainly used to accommodate and protect the motor. At the same time, it is also an important way to achieve vehicle lightweight and improve energy efficiency. During its processing, molds are often used. Using molds for processing can reduce the scrap rate, help the product take shape, and improve production efficiency. Currently, there are various molds for processing automobile motor housings on the market, but there are still some disadvantages.

[0003] For the existing molds for processing automobile motor housings, the waiting time of workers is reduced by increasing the speed at which the stamping parts are separated from the mold. However, the mold demoulding process is relatively cumbersome, reducing the demoulding speed of the stamping parts. During the stamping process of the stamping parts, the mold is not fixed, which will cause deviation and affect the forming accuracy of the stamping parts. At the same time, during the forming process of the stamping parts, static cooling is often required, greatly reducing the production efficiency of the stamping parts. For example, the Chinese utility model patent with the authorization announcement number CN213997464U discloses a mold for a new energy vehicle motor housing, including a workbench, a lower template, and an upper template. A limiting plate is fixedly connected to the workbench, a threaded rod is threadedly connected to the limiting plate, a fixing frame is fixedly connected to the upper template, a sliding rod is slidably connected to the fixing frame, a blocking block is fixedly connected to the sliding rod, the blocking block abuts against the fixing frame, a first spring is sleeved on the outer wall of the sliding rod, and the two ends of the first spring respectively abut against the upper template and the blocking block. A through groove is opened on the upper template, the sliding rod is slidably connected in the through groove, and a pressing block is fixedly connected to the sliding rod. The utility model is simple to use. By raising the upper template to drive the pressing block on the sliding rod to abut against the stamping part, the stamping part is separated from the upper template, reducing the labor intensity of manual extraction and improving the stamping work efficiency. However, this device reduces the waiting time of workers by increasing the speed at which the stamping parts are separated from the mold. However, the mold demoulding process is relatively cumbersome, reducing the demoulding speed of the stamping parts. During the stamping process of the stamping parts, the mold is not fixed, which will cause deviation and affect the forming accuracy of the stamping parts. At the same time, during the forming process of the stamping parts, static cooling is often required, greatly reducing the production efficiency of the stamping parts. Therefore, we propose a mold for processing an automobile motor housing with rapid cooling to solve the problems mentioned above. Summary of the Utility Model

Detailed Embodiment

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0032] Embodiment 1: To solve the problems existing in the prior art, therefore, in this embodiment, through the following technical solutions, a mold for machining an automotive motor housing with rapid cooling is provided, which is provided with an operating table 1; a limiting mechanism is arranged on the upper left and right sides of the operating table 1, which can fix the position of the lower mold 2 and improve the forming accuracy of the stamping part; a rapid demolding mechanism is arranged below the moving plate 12. After the stamping part inside the lower mold 2 is formed, the moving plate 12 is moved downward to facilitate the rapid demolding of the stamping part; a rapid cooling mechanism is rotatably arranged on the right side of the support plate 10, which can make the stamping part rapidly cool and form, and can also blow away the residual heat. First, the lower mold 2 is placed above the inside of the placement rack 11, and the placement rack 11 supports the lower mold 2. At the same time, the hydraulic cylinder 9 fixedly installed inside the support plate 10 is opened, and the output end of the hydraulic cylinder 9 will push the support rod 4 to move inward. Since the moving block 5 is arranged on the outer side of the support rod 4, and the first rotating rod 6 and the second rotating rod 7 are rotatably connected to the upper and lower sides of the moving block 5, the first rotating rod 6 is rotatably connected to the support frame 8, and the second rotating rod 7 is rotatably connected to the limiting plate 3. That is, when the support rod 4 moves inward, the moving block 5 will slide on the outer side of the support rod 4, and the first rotating rod 6 and the second rotating rod 7 will rotate. The second rotating rod 7 will push the limiting plate 3 to move inward inside the support frame 8 and can be closely attached to the lower mold 2 to fix the position of the lower mold 2. Then, the electric telescopic rod 18 installed below the front side of the stable frame 19 is opened, so that the output end of the electric telescopic rod 18 pushes the upper mold 17 downward to fit with the lower mold 2. Then, the stamping solution is discharged from the feeding port on the right side of the upper mold 17. Then, the motor body 16 connected to the upper rear side of the rotating frame 20 is opened, and the motor body 16 will make the rotating frame 20 rotate. Since the electric fans 21 are installed on the left and lower sides of the rotating frame 20, that is, when the electric fan 21 on the left side of the rotating frame 20 is opened, the lower mold 2 can be blown and cooled on the outer side of the lower mold 2, so that the solution inside the lower mold 2 is rapidly formed. After the solution is formed, the upper mold 17 is opened, and then the electric fan 21 below the rotating frame 20 is rotated to the upper side of the lower mold 2, and the inside of the lower mold 2 is blown to take away the residual heat of the formed stamping part. After the stamping part is formed, since the moving plate 12 is installed below the inside of the lower mold 2, that is, the motor body 16 connected to the rear end of the outer side of the connecting rod 15 is opened, and the motor body 16 will make the connecting rod 15 rotate. Since the push rod 13 is rotatably connected to the inner side of the connecting rod 15, the push rod 13 is located inside the fixed frame 14. In addition, the moving plate 12 is fixedly connected to the upper side of the push rod 13. That is, when the connecting rod 15 rotates, it will pull the push rod 13 to slide inside the fixed frame 14, and the push rod 13 can drive the connected moving plate 12 to move downward to facilitate the rapid demolding of the stamping part inside the lower mold 2.

[0033] In the existing mold, during the stamping process of the stamping part, the mold is not fixed, which will cause offset and affect the forming precision of the stamping part. Therefore, in this embodiment, through the following technical solutions, such as Figure 1 , Figure 2 and Figure 4 shown, the limiting mechanism includes support plates 10 symmetrically arranged on the left and right above the operating table 1. A hydraulic cylinder 9 is installed inside the support plate 10. That is, when the hydraulic cylinder 9 is opened, the output end of the hydraulic cylinder 9 can push the connected support rod 4 to move inward. A moving block 5 is installed outside the support rod 4. The first rotating rod 6 and the second rotating rod 7 are respectively rotatably connected to the upper and lower sides of the moving block 5. One side of the first rotating rod 6 is rotatably connected to the support frame 8, and one side of the second rotating rod 7 is rotatably connected to the limiting plate 3. That is, when the support rod 4 moves inward, the moving block 5 will slide outside the support rod 4, and the first rotating rod 6 and the second rotating rod 7 will rotate. The second rotating rod 7 will push the connected limiting plate 3 to move inward and closely fit with the lower mold 2 to limit the lower mold 2.

[0034] Embodiment 2: In the existing mold, the demolding process is rather cumbersome, reducing the demolding speed of the stamping part. Therefore, in this embodiment, through the following technical solutions, such as Figure 2 and Figure 6 shown, the quick demolding mechanism includes a moving plate 12 arranged below the lower mold 2. Push rods 13 are symmetrically and fixedly connected to the left and right below the moving plate 12. The push rods 13 are arranged inside the fixed frame 14. The upper part of the fixed frame 14 is connected to the operating table 1 for fixed support. At the same time, the lower part of the push rod 13 is rotatably connected to the connecting rod 15, and the outer rear end of the connecting rod 15 is connected to the motor body 16. That is, when the motor body 16 is opened, the motor body 16 will cause the connecting rod 15 to rotate. When the connecting rod 15 rotates, it will cause the push rod 13 to move up and down inside the fixed frame 14. The push rod 13 can pull the connected moving plate 12 to move downward to quickly demold the stamping part formed inside the lower mold 2.

[0035] Embodiment 3: In the existing mold, it often needs to be left standing for cooling, which greatly reduces the production efficiency of the stamping part and other problems. Therefore, in this embodiment, through the following technical solutions, such as Figure 1 and Figure 2 shown, the quick cooling mechanism includes a rotating frame 20 arranged inside the right side of the support plate 10. When the motor body 16 connected to the upper rear side of the rotating frame 20 is opened, the rotating frame 20 will rotate. The electric fan 21 on the left side outside the rotating frame 20 can blow air towards the outside of the lower mold 2, enabling the stamping part inside the lower mold 2 to be quickly formed. After the stamping part is formed, when the upper mold 17 is opened, the electric fan 21 installed below the rotating frame 20 rotates to blow air towards the lower inner side of the lower mold 2, which can blow away the residual heat.
