Description

Technical Field

[0001] The invention relates to the technical field of automobile transmission, and in particular to a molding device for machining an automobile transmission housing. Background Art

[0002] As a key component in the automobile transmission system, the structure and performance of the transmission housing directly affect the smoothness of the vehicle's gear shifting and transmission efficiency. In order to meet the high-precision and high-strength processing requirements, die-casting technology is widely used in the manufacturing process of the transmission housing. Through die-casting, it can ensure that the housing has precise dimensions, good surface quality and excellent mechanical properties.

[0003] According to the patent application number CN202321212133.6, the prior art pushes the push plate downward by a stamping cylinder, and performs movement and limiting processing on the push plate through the sliding connection between the slide groove and the fixed shaft, and the push plate drives the die-casting mold to be inserted into the die-casting groove, and the molten metal in the crucible body is sprayed into the die-casting groove through the nozzle. After molding, the stamping cylinder drives the die-casting mold to move upward, and the start motor drives the threaded rod to rotate, and the connecting plate is driven to move upward through the screw connection between the threaded rod and the threaded barrel, and the push rod is pushed upward by the connecting plate, and the push rod is moved and limited through the sliding connection between the push rod and the limit groove, and the die-casting is ejected by the push rod, thereby realizing easy material removal processing of the die-casting.

[0004] In the above patent, the push plate drives the die-casting mold to slide up and down along the guide shaft. Although it plays a certain guiding role for the die-casting mold, after long-term operation, the surface of the guide shaft is easily contaminated with dust, affecting the surface finish of the guide shaft. These dust particles will cause wear on the contact surface between the push plate and the guide shaft, which will make the push plate move less smoothly and even shake, affecting the die-casting accuracy of the gearbox housing.

[0005] When the push plate loaded with the male mold is pressed down to the female mold by the cylinder, the downward pressure of the telescopic shaft of the cylinder is too concentrated and cannot be evenly distributed in all directions of the push plate. This results in the contact surface not being completely closed when the male mold is pressed down to the female mold, thus affecting the quality and consistency of the die casting.

[0006] Therefore, in view of the shortcomings of the existing technology, we urgently need a molding device for automobile gearbox housing processing to solve these problems. This new device should be able to effectively ensure the smoothness of the guide shaft and ensure that the push plate moves smoothly and stably; at the same time, it should also be able to optimize the distribution of the cylinder pressure and ensure that the contact surface between the male mold and the female mold can be completely closed, thereby improving the accuracy and quality of the die casting.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1

[0037] See also Figure 1-9 As shown, a molding device for processing an automobile gearbox housing in this embodiment comprises a loading frame 2, a control module 1 and a die-casting module 3;

[0038] Loading frame 2: As the supporting structure of the entire automobile gearbox housing processing molding device, it stably carries the control module 1 and the die-casting module 3 to ensure the stability and reliability of the entire device during operation.

[0039] Die-casting module 3: used for die-casting the automobile gearbox housing. It includes a top plate 4, a bottom plate 8 and a push plate 7. The die-casting of the housing is achieved through the cooperation of the three.

[0040] The die casting module 3 comprises a top plate 4, a bottom plate 8 and a push plate 7;

[0041] The top plate 4 and the bottom plate 8 are connected by four guide shafts 12. The push plate 7 is arranged between the top plate 4 and the bottom plate 8 and the four corners are slidably connected to the guide shafts 12 through guide sleeves 13. A downward pressure cylinder 11 is installed at the top center of the top plate 4, and the output end of the downward pressure cylinder 11 is connected to the top of the push plate 7 through an adjustable pressure divider assembly 5.

[0042] Adjustable pressure-dividing assembly 5: connected between the output end of the downward pressure cylinder 11 and the top of the push plate 7, used to adjust the distribution of the downward pressure on the push plate 7. By adjusting the adjustable pressure-dividing assembly 5, the downward pressure can be concentrated or evenly dispersed on the push plate 7, thereby improving the distribution and uniformity of the downward pressure during the die-casting process.

[0043] Cleaning modules 6 are provided on both sides of the top and bottom of the push plate 7 , and the cleaning module 6 is provided with two cleaning ends, which are connected to the adjacent guide sleeves 13 and are used to clean the surface of the guide shaft 12 .

[0044] Cleaning module 6: It is arranged on both sides of the top and bottom of the push plate 7 and is used to clean the surface of the guide shaft 12. During the movement of the push plate 7, the cleaning module 6 will simultaneously clean the guide shaft 12 to maintain its finish, thereby ensuring that the push plate 7 moves smoothly and stably, which helps to improve the precision and overall quality of die casting.

[0045] Working principle of the present invention: In the molding device for processing automobile gearbox housing, the loading frame 2 serves as the supporting structure of the entire device, stably carrying the control module 1 and the die-casting module 3. The die-casting module 3 is composed of a top plate 4, a bottom plate 8 and a push plate 7.

The push plate 7 is arranged between the top plate 4 and the bottom plate 8, and its four corners are slidably connected to the guide shaft 12 through the guide sleeve 13, so that the push plate 7 can slide up and down along the guide shaft 12 while maintaining good guidance.

[0046] During die casting, the output end of the downward pressure cylinder 11 is connected to the top of the push plate 7 through the adjustable pressure dividing assembly 5. The adjustable pressure dividing assembly 5 can adjust the concentration and distribution of the downward pressure as needed to ensure that the downward pressure acts evenly on the push plate 7.

[0047] With the push of the downward pressure cylinder 11, the push plate 7 moves downward along the guide shaft 12, and at the same time drives the tooling to be pressed into the mother mold. During the movement of the push plate 7, the cleaning module 6 can synchronously clean the guide shaft 12. The cleaning module 6 is arranged on both sides of the top and bottom of the push plate 7. Each cleaning module 6 is provided with two cleaning ends and cooperates with the adjacent guide shafts 12 respectively. When the push plate 7 moves up and down, the cleaning end will synchronously slide on the guide shaft 12 along with the guide sleeve 13, and the sliding of the cleaning end can clean the surface of the guide shaft 12. In this way, the dust and impurities on the surface of the guide shaft 12 can be effectively removed, and its finish can be maintained, thereby ensuring that the push plate 7 moves smoothly and stably.

[0048] Embodiment 2

[0049] A molding device for processing an automobile gearbox housing according to this embodiment, such as Figure 1-9 As shown, one side of the die-casting module 3 is rotatably connected to the inner wall of the loading frame 2 through a rotating bracket 10, and one side of the loading frame 2 is connected to a pushing cylinder 9 through a rotating seat. The output end of the pushing cylinder 9 is connected to the side wall of the loading frame 2 through an ear seat. The rotation of the die-casting module 3 can be realized by cooperating with the pushing cylinder 9 and the rotating bracket 10. By rotating the die-casting module 3, its inclination angle can be adjusted to facilitate loading and unloading operations.

[0050] Four slide grooves 502 are provided on the top of the push plate 7, and a mounting groove 505 connected to the four slide grooves 502 is provided at the center of the top. The adjustable pressure dividing assembly 5 includes an electromagnet 504, four sliders 508 and a lifting column 501. The electromagnet 504 is connected at the inner center of the mounting groove 505, and the four sliders 508 are respectively slidably connected inside the four slide grooves 502. The top of each slider 508 is connected to a magnetic attraction member for magnetically cooperating with the electromagnet 504. A support rod 507 is provided on the top of the magnetic attraction member. One end of the support rod 507 is rotatably connected to the top of the magnetic attraction member, and the other end is rotatably connected to the side wall of the lifting column 501. The end of the lifting column 501 is connected to the output end of the downward pressure cylinder 11.

[0051] The outer cover of the electromagnet 504 is provided with a protective shell, and a supporting cylinder is installed on the top of the protective shell. The output shaft of the supporting cylinder is connected to the bottom end of the lifting column 501, so as to improve the connection stability between the push plate 7 and the lifting column 501 and relieve the pressure of the four support rods 507. The magnetic suction part includes a pressing block 503 and a magnet block connected to the inside of the pressing block 503 and used for magnetically cooperating with the electromagnet 504. The bottom of the pressing block 503 is fixedly connected to the top of the slider 508, and one side of the pressing block 503 is provided with an inner arc surface adapted to the shape of the outer wall of the protective shell.

[0052] A plurality of rotation grooves 506 are formed at the bottom of the outer ring of the lifting column 501 . One end of the support rod 507 is rotationally connected to the inside of the rotation groove 506 via a pin, and the other end is connected to the top of the lower pressing block 503 via an ear seat.

[0053] One end of the slider 508 is connected to a mounting plate 511 connected to the inner wall of the slide slot 502 via a return spring 509 , and one side of the mounting plate 511 is connected to two abutment posts 510 .

[0054] The present embodiment is a molding device for processing a car gearbox housing. Through the coordination of the electromagnet 504, the slider 508, the lifting column 501, and the pressing block 503 and the magnet block of the magnetic suction member in the adjustable pressure-dividing assembly 5, the uniform distribution of the downward pressure on the push plate 7 is achieved. When the electromagnet 504 is energized, the pressing blocks 503 at the top of the four sliders 508 are attracted to move toward the center, and the magnet block and the electromagnet 504 are magnetically fixed. At this time, the four support rods 507 are close to form a concentrated downward pressure. When the electromagnet 504 is powered off, the reset spring 509 pulls the slider 508 and the pressing block 503 to move toward the position of the mounting plate 511 until the side wall of the slider 508 contacts the abutment column 510. At this time, the four support rods 507 are separated from each other and opened, and at the same time, the four pressing blocks 503 are separated from each other, forming a distributed downward pressure on the top of the push plate 7.

[0055] The downward pressure cylinder 11 pushes the lifting column 501 to move downward. By turning the electromagnet 504 on and off, it can switch between the centralized downward pressure mode and the distributed downward pressure mode, avoiding the problem of excessive concentration of downward pressure in traditional technology. The controllability of the electromagnet 504 can also realize rapid adjustment of the downward pressure mode, thereby improving the precision and quality of the die-casting.

[0056] During the die-casting process, the contact surface between the male mold and the female mold can be completely closed by switching between centralized down pressure and distributed down pressure, thereby improving the quality and consistency of the die-casting parts and the accuracy and stability of the die-casting.

[0057] Embodiment 3

[0058] A molding device for processing an automobile gearbox housing according to this embodiment, such as Figure 1-9 As shown,

[0059] The cleaning module 6 includes an airbag 601, and the cleaning end includes an annular shell 602. The inner ring of the annular shell 602 is provided with an annular groove connected to the interior. The inner rotation of the annular groove is connected with a rotating ring 606. The inner ring of the rotating ring 606 is connected with a cleaning ring 608 for contacting the outer ring of the guide shaft 12. The outer ring is connected with a plurality of fan blades 609 arranged inside the annular shell 602. The air outlet end of the airbag 601 is connected with the interior of the two annular shells 602 through an air supply structure, which is used to blow the fan blades 609 to drive the rotating ring 606 to rotate.

[0060] The cleaning ring 608 is detachably connected to the inner wall of the rotating ring 606, and the inner wall of the cleaning ring 608 is provided with a plurality of flexible cleaning bristles.

[0061] One end of the airbag 601 is connected to the side wall of the push plate 7, and the other end is connected to the side wall of the top plate 4 or the bottom plate 8. The air inlet and outlet ends of the airbag 601 are both connected to a one-way valve. Several fan blades 609 are arranged in a circular array along the circumferential direction of the rotating ring 606, and several fan blades 609 are arranged at an angle.

[0062] One side of the annular shell 602 is connected to the guide sleeve 13 through a plurality of fixed columns 607. One side of the annular shell 602 is connected to an exhaust pipe 605. The air supply structure includes a diverter pipe 603 and an air supply pipe 604. Both ends of the diverter pipe 603 are respectively connected to the interior of the annular shell 602.

[0063] A molding device for processing an automobile gearbox housing in this embodiment realizes the cleaning of the surface of the guide shaft 12 through the coordinated work of the airbag 601, the annular shell 602, the rotating ring 606, the cleaning ring 608 and the fan blade 609 in the cleaning module 6. When the push plate 7 moves up and down, the airbag 601 is squeezed or stretched, and the inlet and outlet of the gas are controlled by the one-way valve to send the gas into the inside of the annular shell 602. The gas blows the fan blade 609 to rotate, and then drives the rotating ring 606 and the cleaning ring 608 to rotate. The gas flows inside the annular shell 602 to drive the fan blade 609 to rotate, and finally it will be discharged through the exhaust pipe 605 to ensure the rationality of the airflow. The flexible cleaning bristles on the inner wall of the cleaning ring 608 are in contact with the surface of the guide shaft 12, and dust and impurities are removed through the rotational motion.

[0064] With each movement of the push plate 7, the cleaning module 6 automatically cleans the guide shaft 12. This not only ensures the smoothness of the surface of the guide shaft 12, but also avoids the problem of the push plate 7 moving poorly or shaking due to dust accumulation. At the same time, the detachable connection design between the cleaning ring 608 and the rotating ring 606 facilitates the replacement and maintenance of the cleaning ring 608.

[0065] The surface of the guide shaft 12 is always kept clean and smooth, and the movement of the push plate 7 is smoother and more stable, thereby improving the die-casting accuracy and overall quality of the gearbox housing.

[0066] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
