Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a molding mold for an automotive motor carbon brush holder. Background Technology

[0002] Automotive motor brush holders are used to hold carbon brushes in place and ensure good contact between the brushes and the motor's commutator. This allows for stable current transmission to the motor rotor, ensuring normal motor operation. Simultaneously, the brush holder allows for timely repositioning of the brushes as they wear down, extending the lifespan of both the brushes and the commutator, improving motor efficiency and reliability, and reducing the probability of malfunctions.

[0003] Automotive motor carbon brush holder molding dies utilize molds and specific processes to shape materials into the desired brush holder shape within the mold by applying pressure and heat. During operation, molten material is injected into the mold cavity, and after cooling and solidification, the desired carbon brush holder is obtained. Its primary application is in automotive parts manufacturing plants for mass production of carbon brush holders to meet the demands of automotive motor manufacturing, ensuring the dimensional accuracy and quality stability of the carbon brush holders.

[0004] In existing technologies, some automotive motor carbon brush holder forming dies are often manually loaded with the die during stamping. Manual loading makes it difficult to ensure that the position and posture of the loading are completely consistent each time, which can easily lead to deviations. This may result in uneven stress on the die during stamping, affecting the forming accuracy of the carbon brush holder, increasing the defect rate, and making it difficult to maintain a stable loading rhythm, which cannot meet the needs of large-scale, high-efficiency production. Therefore, an automotive motor carbon brush holder forming die is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a molding die for carbon brush holders of automobile motors, which aims to improve the problems in the existing technology where some molding dies for carbon brush holders of automobile motors often require manual loading of the mold to be processed during stamping, which makes it difficult to meet production needs and causes deviations during stamping.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A carbon brush holder forming mold for an automotive motor includes two fixed frames, each fixed frame having a stepping belt rotatably mounted on a close side, each stepping belt having stepping grooves on both sides, a fixed post fixedly connected to the outer wall of the fixed frame, a forming component installed at the bottom of the fixed post, a stepping transmission mechanism installed on the inner wall of the fixed frame, and a carbon brush holder placed on top of the stepping belt.

[0008] Through the above technical solution: two fixed frames are used to support components such as stepper belt, fixed pile, and stepper transmission mechanism. The rotation of the stepper belt can drive the carbon brush holder placed on top of it to move. The stepper groove can cooperate with the stepper rod to realize the stepper belt's stepping movement. The fixed pile is used to install the molding component. The stepper transmission mechanism can drive the stepper belt to move step by step, thereby realizing the feeding of the carbon brush holder and conveying the carbon brush holder to the bottom of the molding component for processing.

[0009] The stepping transmission mechanism includes a fixed plate, a drive motor is fixedly connected to the inner wall of the fixed plate, and a drive assembly is fixedly connected to the drive end of the drive motor.

[0010] Through the above technical solution: the fixing plate is used to install and fix the drive motor and drive component. When the drive motor is started, it can drive the drive component to rotate. The rotation of the drive component can transmit the power of the drive motor, thereby realizing the movement of the stepper transmission mechanism, driving the stepper belt to move, and then driving the carbon brush holder to move to the bottom of the molding component for processing.

[0011] As a further description of the above technical solution:

[0012] The molding component includes a cylinder, a molding pile is fixedly connected to the driving end of the cylinder, a molding module is fixedly connected inside the molding pile, and a top template is slidably connected to the outer wall of the molding module.

[0013] Through the above technical solution: the cylinder can drive the forming pile to move downward, and the downward movement of the forming pile can enable the forming module to stamp and form the carbon brush holder. The shape of the forming module matches the shape of the carbon brush holder, which can accurately form the carbon brush holder. The top template can slide inside the forming pile with the movement of the top mold rod. After the stamping is completed, the top template can push the processed carbon brush holder out from the forming pile to complete the demolding operation.

[0014] The bottom of the fixed pile is fixedly connected to two top mold rods, and the outer walls of the two top mold rods are slidably connected to the inner wall of the formed pile.

[0015] Through the above technical solution: the top mold rod is slidably connected to the forming pile. When the cylinder drives the forming pile to rise, the top mold rod can slide on the inner wall of the forming pile. The sliding of the top mold rod can drive the top template to slide, thereby pushing the processed carbon brush holder out from the inner wall of the forming pile to complete the demolding. The top mold rod plays the role of transmitting power and making the top template move.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the formed pile is fixedly connected with a fixing ring, and the top of the fixing frame is fixedly connected with a fixing ring.

[0018] Through the above technical solution: the fixing ring can play a certain role in fixing and supporting the forming pile, ensuring the stability of the forming pile during the working process; the fixing ring is used to connect the fixing frame and the shock-absorbing spring; the shock-absorbing spring can connect the fixing ring and the forming pile, playing a damping and buffering role in the stamping process of the forming pile, preventing excessive force from damaging the carbon brush frame during the stamping of the forming pile.

[0019] The drive assembly includes a drive rod, the outer wall of which is fixedly connected to the drive end of the drive motor. A rotating rod one is fixedly connected to the outer wall of the drive rod. A control rod is rotatably connected to the outer wall of the rotating rod one. A rotating rod two is rotatably connected to the outer wall of the control rod. The outer wall of the rotating rod two is rotatably connected to the inner wall of the fixed plate.

[0020] Through the above technical solution: the drive motor drives the drive rod to rotate, the drive rod rotates the first rotating rod to rotate, the first rotating rod rotates the control rod to rotate, the control rod rotates the second rotating rod to rotate, and the second rotating rod is rotatably connected to the fixed plate. The rotatable connection between the control rod, the first rotating rod and the second rotating rod can convert the rotation of the drive rod into the stepping movement of the long rod, thereby driving the stepping belt to move and realizing the stepping feeding of the carbon brush holder.

[0021] A fixing rod is fixedly connected to the top of the control rod, and a connecting rod is rotatably connected to the inner wall of the fixing rod;

[0022] Through the above technical solution: the fixed rod and the control rod are fixedly connected, so that the movement of the control rod can be transmitted to the connecting rod. The connecting rod and the fixed rod are rotatably connected, so that the connecting rod can rotate within a certain range. The connecting rod can further transmit the movement of the fixed rod to the long rod, thereby driving the long rod to move in a stepping manner, realizing the stepping movement of the stepping belt.

[0023] As a further description of the above technical solution:

[0024] The top of the connecting rod is fixedly connected to a long rod, and the top of the long rod is fixedly connected to a plurality of stepping rods. The outer wall of the stepping rod is slidably connected to the inner wall of the stepping groove.

[0025] Through the above technical solution: the connecting rod drives the long rod to move, the long rod drives the stepping rod to move, the stepping rod is slidably connected to the stepping groove, the stepping rod is inserted into the inner wall of the stepping groove to drive the stepping belt to move, multiple stepping rods can ensure the stability of the stepping belt movement, realize the stepping feeding of the carbon brush holder, and transport the carbon brush holder to the bottom of the molding component for processing in sequence.

[0026] Multiple shock-absorbing springs are fixedly connected to the top of the fixing ring, and the shape of the molding module matches the shape of the carbon brush holder.

[0027] The above technical solution involves multiple shock-absorbing springs connecting the fixing ring and the forming pile. During the stamping of the forming pile, the shock-absorbing springs can dampen and buffer the stamping of the forming pile, preventing excessive force from damaging the carbon brush holder. The forming module matches the shape of the carbon brush holder, enabling precise stamping and forming of the carbon brush holder, thus ensuring the processing quality of the carbon brush holder.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the start of the drive motor drives the drive rod to rotate, the rotation of the drive rod drives the first rotating rod to rotate, the rotation of the first rotating rod drives the control rod to rotate, thereby driving the second rotating rod to rotate, causing the fixed rod to move stepwise, thereby driving the long rod to move stepwise, so that the top stepping rod is engaged with the inner wall of the stepping groove on both sides of the stepping belt, thereby driving the stepping belt to move once to send the carbon brush holder into the bottom of the forming component. After the forming component at the bottom of the fixed post has completed the processing of the carbon brush holder, the drive motor starts to drive the processed carbon brush holder to move out of the bottom of the forming component, thereby driving the unprocessed carbon brush holder to the bottom of the forming component, thus completing the step-by-step feeding, making the feeding more accurate.

[0030] 2. In this utility model, the cylinder starts and drives the forming pile to move downward. At this time, the forming module stamps the carbon brush holder to be processed. After the stamping is completed, the cylinder drives the forming pile to rise, causing the top mold rod to slide on the inner wall of the forming pile. Then, the sliding of the top mold rod will drive the top template to slide, thereby pushing the processed carbon brush holder out from the inner wall of the forming pile, thus completing the demolding. During the stamping, the shock-absorbing spring will dampen the stamping of the forming pile to prevent the force of the forming pile from being too large and damaging the carbon brush holder.

[0045] Reference Figure 1 , Figure 4 and Figure 5 The forming component 4 includes a cylinder 45, which provides power to the forming pile 42. The driving end of the cylinder 45 is fixedly connected to the forming pile 42. The forming pile 42 can move up and down under the drive of the cylinder 45.

[0049] Working principle: When the carbon brush holder 7 needs to be transferred, the drive motor 22 starts. The start of the drive motor 22 drives the drive rod 231 to rotate.

The rotation of the control rod 237 drives the second rotating rod 236 to rotate. The rotation of the control rod 237 causes the fixed rod 233 to move stepwise, thereby driving the long rod 235 to move stepwise. The stepping movement of the long rod 235 causes the top stepping rod 238 to engage with the inner wall of the stepping groove 6 on both sides of the stepping belt 5, thereby driving the stepping belt 5 to move once to send the carbon brush holder 7 to the bottom of the forming component 4. After the forming component 4 at the bottom of the fixed pile 3 has finished processing the carbon brush holder 7, the drive motor 22 starts to drive the processed carbon brush holder 7 to move out of the bottom of the forming component 4, thereby driving the unprocessed carbon brush holder 7 to the bottom of the forming component 4, thus completing the stepping feeding.

[0050] When the carbon brush holder 7 needs to be stamped, the cylinder 45 is activated to move the forming post 42 downward. Then, the forming module stamps the carbon brush holder 7 to be processed. After the stamping is completed, the cylinder 45 drives the forming post 42 to rise, causing the top die rod 41 to slide on the inner wall of the forming post 42. The sliding of the top die rod 41 will drive the top die plate 43 to slide, thereby pushing the processed carbon brush holder 7 out from the inner wall of the forming post 42 to complete the demolding. During the stamping, the shock-absorbing spring 44 will dampen the stamping of the forming post 42 to prevent the force of the forming post 42 from being too great and damaging the carbon brush holder 7.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
