Description

Technical Field

[0001] This invention relates to the field of die casting equipment technology, and in particular to a die casting apparatus for a precision thin-walled motor housing. Background Technology

[0002] Die casting is a precision casting process in which molten metal is injected into a mold under pressure, cooled and shaped, and then solidified into a solid metal casting after the mold is opened. Die castings made by die casting have higher mechanical strength than castings made by ordinary casting. In the production of motor housings, die casting molding equipment is often used to cast motor housings.

[0003] In the existing technology, when precision thin-walled motor housings are die-cast, due to their thinness, they are prone to deformation after being removed from the die-casting mold and cooled down, as there is no other supporting force inside the motor housing. In addition, during the process of removing the motor housing from the mold, it may stick to the mold and be difficult to remove. At the same time, the mold itself may also have certain impurities adhering to it, which will affect the subsequent die-casting quality of the motor housing. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a die-casting molding device for precision thin-walled motor housings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] Preferably, the adjustment mechanism includes an electric telescopic rod and a third connecting plate. The fixed end of the electric telescopic rod is connected to one side of the outer wall of the corresponding second electric slider. One side of the outer wall of the third connecting plate is connected to the extended end of the electric telescopic rod. The bottom of the third connecting plate is connected to the top of the corresponding scraper through a first electric rotating rod. A second electric rotating rod is also connected between the extended end of the electric telescopic rod and one side of the outer wall of the third connecting plate.

[0010] Preferably, the bottom of the scraper is provided with a plurality of second air holes, and both ends of the top of the scraper are provided with a plurality of first air holes. A first air box is provided at the top of the first mold closing end, and the first air holes are connected to the second air holes.

[0011] Preferably, a second mounting plate is installed on one side of the outer wall of the second mold closing end, a first cleaning cylinder is slidably installed on one side of the outer wall of the second mounting plate along its width direction, and an outer mold is also slidably installed on one side of the outer wall of the second mounting plate along its width direction.

[0012] Preferably, a third groove is provided on one side of the outer wall of the second mounting plate along its width direction. Two third electric sliders are slidably installed inside the third groove. The outer mold is connected to one side of the outer wall of one of the third electric sliders, and the first cleaning cylinder is connected to one side of the outer wall of the other third electric slider.

[0013] Preferably, a second connecting plate is connected to the bottom end of one side of the outer wall of the die-casting device body. Multiple second cleaning cylinders are installed on the top of the second connecting plate along its length. Multiple grooves are opened at both the upper and lower ends of the second cleaning cylinders along the circumferential direction. A baffle is rotatably installed inside the groove. The baffle is rotatably connected inside the groove by a torsion spring.

[0014] Preferably, the top of the second connecting plate is provided with an arc-shaped through groove with suction function on both sides of the outer wall of each second cleaning cylinder, and a second air box is installed at the bottom of the second connecting plate. The through groove is connected to the second air box through a hose.

[0015] Preferably, the top of the second connecting plate is connected to a plurality of third electric rotating rods along its length, the top of the third electric rotating rods is connected to an electric suction cup, the top of the electric suction cup is connected to the bottom of the corresponding second cleaning cylinder, the top of one end of the outer wall of one side of the die-casting device body is connected to a first connecting plate, and the bottom of the first connecting plate is connected to a plurality of cameras.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, by setting scrapers, corresponding second electric sliders are adaptively slid inside the two second sliding grooves, so that the outer wall of one side of the two scrapers is attached to the outer wall of the motor housing. Then, the inner mold is rotated by the fourth electric rotating rod between the first electric slider and the inner mold. After the inner mold rotates, the surface of the motor housing that needs to be scraped is rotated to the bottom of the upper scraper. Then, the lower scraper abuts against and fixes the motor housing, while the upper scraper scrapes and cleans the outer wall of the motor housing. The lower scraper abuts against and prevents the motor housing from falling off the outer wall of the inner mold during the scraping process.

[0018] 2. In this invention, by setting an adjustment mechanism, when the die-cast motor housing is barrel-shaped with only one end open, when it is necessary to scrape and clean the inner wall of the motor housing, after the two scrapers abut and fix the motor housing, the corresponding first electric rotating rod will synchronously rotate the scrapers 180 degrees so that the opening of the motor housing faces the first cleaning cylinder, and then the inner wall of the motor housing will be scraped and cleaned by the first cleaning cylinder.

[0019] 3. In this invention, by setting a second cleaning cylinder and baffles, each baffle on the top of the second cleaning cylinder is rotated upwards by 90 degrees using a robotic arm or manually. After the motor housing is fitted onto the outside of the second cleaning cylinder, the baffles are reset. The baffles protect the ends of the motor housing. During subsequent transportation and processing, the second cleaning cylinder and the motor housing are transported together, preventing wear on the ends of the motor housing during transport, which would affect its subsequent use. Furthermore, the support of the second cleaning cylinder also prevents deformation of the motor housing during transport due to its thinness and the mutual compression between the individual motor housings.

It should be noted that a fourth electric rotating rod is connected between the outer mold 11 and the first cleaning cylinder 10 and their respective third electric sliders 23, as well as between the first electric slider 16 and the inner mold 8. One side of the outer wall of the outer mold 11 and the inner mold 8 is connected to their respective third electric sliders 23 and first electric sliders 16 by bolt threads. The first cleaning cylinder 10 is connected to its corresponding third electric slider 23 by bolt threads.

[0041] As a technical optimization of the present invention, a second connecting plate 6 is connected to the bottom end of one side of the outer wall of the die-casting device body 1. A plurality of second cleaning cylinders 26 are installed on the top of the second connecting plate 6 along its length direction. A plurality of grooves 28 are opened at both the upper and lower ends of the second cleaning cylinders 26 along the circumferential direction. A baffle 30 is rotatably installed inside the groove 28. The baffle 30 is rotatably connected inside the groove 28 by a torsion spring 29.

[0042] As a technical optimization of the present invention, the top of the second connecting plate 6 is provided with an arc-shaped through groove 27 with air suction function on both sides of the outer wall of each second cleaning cylinder 26, and the bottom of the second connecting plate 6 is equipped with a second air box 25. The through groove 27 is connected to the second air box 25 through a hose.

[0043] As a technical optimization of the present invention, the top of the second connecting plate 6 is connected to a plurality of third electric rotating rods 33 along its length direction, the top of the third electric rotating rods 33 is connected to an electric suction cup 31, the top of the electric suction cup 31 is connected to the bottom of the corresponding second cleaning cylinder 26, the top of one end of the outer wall of one side of the die-casting device body 1 is connected to a first connecting plate 5, and the bottom of the first connecting plate 5 is connected to a plurality of cameras 24.

[0044] In use, the die-casting device body 1 is placed in a predetermined position and powered on. When die-casting of a motor housing is required, the first mold-closing end 2 and the second mold-closing end 3 are adjusted horizontally at the top of the die-casting device body 1 as shown in the attached figure. Figure 1 The state shown is as follows. Then, the inner mold 8 to be used is installed on one side of the outer wall of the first mounting plate 7 by an external robotic arm, and the outer mold 11 to be used is installed on one side of the outer wall of the second mounting plate 9 by a robotic arm. After that, the die casting work of the motor housing can begin.

[0045] Furthermore, both the first mold closing end 2 and the second mold closing end 3 are existing technologies, and in the existing technology, the first mold closing end 2 and the second mold closing end 3 can move horizontally on the top of the die casting device body 1.

[0046] After the inner mold 8 and the outer mold 11 are installed, the first mold closing end 2 and the second mold closing end 3 can be moved in opposite directions to close. During the closing process, the inner mold 8 can be inserted into the outer mold 11 to close the mold. Then, the first mold closing end 2 and the second mold closing end 3 cooperate with each other to complete the die casting and shaping of the motor housing.

[0047] When the die-cast motor housing is a cylinder with both ends connected, after the die-casting is completed, the motor housing is cooled down by an external cooling device. Due to the thermal expansion and contraction of the die-cast motor housing, and because of the cylindrical shape of the motor housing, the motor housing will slightly shrink and wrap around the outside of the inner mold 8. Therefore, when the inner mold 8 is removed from the inside of the outer mold 11, the die-cast motor housing will be removed along with the inner mold 8. At the same time, the inner mold 8 itself can support the inside of the die-cast motor housing to prevent the motor housing from deforming after cooling.

[0048] When the die-cast motor housing needs to be initially polished to improve subsequent processing efficiency, the corresponding second electric sliders 15 are adaptively slid inside the two second slide grooves 14, so that one side of the outer wall of the two scrapers 12 is attached to the outer wall of the motor housing. Then, the inner mold 8 is rotated by the fourth electric rotating rod between the first electric slider 16 and the inner mold 8. After the inner mold 8 rotates, the surface of the motor housing that needs to be scraped is rotated to the bottom of the upper scraper 12. Then, the lower scraper 12 abuts and fixes the motor housing, while the upper scraper 12 scrapes and cleans the outer wall of the motor housing. The abutment of the lower scraper 12 can prevent the motor housing from falling off the outer wall of the inner mold 8 during the scraping process. Furthermore, during the scraping and cleaning of the outer wall of the motor housing by the scraper 12, the first air box 4 is activated. After the first air box 4 is activated, the second air hole 21 located at the bottom of the scraper 12 can absorb the scraped waste residue. At the same time, the first air holes 20 located on both sides of the outer wall of the scraper 12 at the bottom can absorb the waste residue that falls onto the top surface of the die-casting device body 1, preventing the waste residue from affecting the subsequent die-casting work. It should also be noted that, due to thermal expansion and contraction, the motor housing is wrapped around the outer wall of the inner mold 8. Rotating the motor housing together with the inner mold 8 before processing will not prevent the inner mold 8 from adjusting the position of the motor housing during the processing.

[0049] After the outer wall of the motor housing is polished and the motor housing needs to be removed from the outer wall of the inner mold 8, the inner wall of the motor housing is polished. First, the two scrapers 12 are slid adaptively to fix the motor housing in contact with each other. Then, the electric telescopic rod 17 is extended outward to remove the motor housing from the outer wall of the inner mold 8. Next, the first cleaning cylinder 10 and the outer mold 11 are slid adaptively on the inner wall of the third groove 22 on the outer wall of the second mounting plate 9 via the third electric slider 23. The first cleaning cylinder 10 is aligned with the inner mold 8, while the outer mold 11 is moved to one side of the first cleaning cylinder 10. Then, the motor housing is fitted onto the outside of the first cleaning cylinder 10 by the two scrapers 12. The first cleaning cylinder 10 is rotated by the fourth electric rotating rod between the first cleaning cylinder 10 and the corresponding third electric slider 23. The first cleaning cylinder 10 can scrape and polish the inner wall of the motor housing to improve the efficiency of subsequent processing.

[0050] When impurities are present inside the outer mold 11 and cleaning of the interior is required, the position of the outer mold 11 can be adjusted by sliding so that it aligns with the two scrapers 12. The scrapers 12 can be inserted into the outer mold 11. After insertion, the position of the two scrapers 12 is adjusted accordingly, and the two scrapers 12 are rotated 180 degrees so that the second air hole 21 at the bottom of the scraper 12 faces the inner wall of the outer mold 11. The scrapers 12 can then adhere to the inner wall of the outer mold 11. Both scrapers 12 are adjusted accordingly so that the corresponding second air hole 21 faces the inner wall of the outer mold 11, thereby scraping and cleaning the inner wall of the outer mold 11.

[0051] Then, the outer mold 11 is rotated by the fourth electric rotating rod between the outer mold 11 and the corresponding third electric slider 23. After the outer mold 11 rotates, the scraper 12 can scrape and clean the outer mold 11. At the same time, the first air hole 20 and the second air hole 21 can both play a certain adsorption role, adsorbing the impurities scraped off during the scraping process of the two scrapers 12.

[0052] When the die-cast motor housing is cylindrical with only one end open, when it is necessary to scrape and clean the inner wall of the motor housing, after the two scrapers 12 are pressed against and fixed to the motor housing, the scrapers 12 are rotated 180 degrees synchronously by the corresponding first electric rotating rod 19, so that the opening of the motor housing faces the first cleaning cylinder 10, and then the inner wall of the motor housing is scraped and cleaned by the first cleaning cylinder 10.

[0053] When the die-cast motor housing is defective, and it is difficult to remove because it is attached to the outer wall of the inner mold 8, and there are impurities on the outer wall of the inner mold 8 after removal, the motor housing can be fixed by two scrapers 12 against each other. Then, the electric telescopic rod 17 can be extended outward to move the scrapers 12 horizontally and remove the motor housing from the outer wall of the inner mold 8. During this process, the inner mold 8 can be rotated to further assist the scrapers 12 in the removal operation and prevent the inner mold 8 from sticking to the motor housing. If some impurities are attached to the outer wall of the inner mold 8 after the motor housing is removed, in order to prevent the impurities from affecting the subsequent die-casting work, the outer wall of the inner mold 8 can be scraped and cleaned by the side wall of the scrapers 12 after they come into contact with the side wall of the inner mold 8. Adaptively retracting the electric telescopic rod 17 and rotating the inner mold 8 can scrape and clean various positions of the outer wall of the inner mold 8 by the scrapers 12. The waste residue generated during cleaning will fall onto the top surface of the die-casting device body 1 and be absorbed by the first air hole 20 of the scraper 12 below.

[0054] When the scraper 12 has accumulated impurities after repeated scraping and cleaning, in order to ensure the normal progress of subsequent cleaning work, the position of the inner mold 8 can be adjusted by sliding the first electric slider 16 through the first slide groove 13, moving the inner mold 8 to one end of the first mounting plate 7. Then, the two scrapers 12 slide in opposite directions, and one scraper 12 is rotated by the corresponding second electric rotating rod 32, while the other scraper 12 does not rotate. During the rotation of one scraper 12, the inner wall of the other scraper 12 can be scraped and cleaned through its side wall. At the same time, the cleaned residue will be absorbed by the corresponding first air hole 20 and second air hole 21. The mutual cleaning between the scrapers 12 can ensure the cleanliness of the scrapers 12 and prevent it from affecting the subsequent cleaning work.

[0055] When the motor housing has completed its initial grinding and cleaning and is ready for transport, a robotic arm can be used to place the motor housing over the idle second cleaning cylinder 26. Before this, the various baffles 30 on the top of the second cleaning cylinder 26 are rotated upwards by 90 degrees using either the robotic arm or manually. After the motor housing is placed over the second cleaning cylinder 26, the baffles 30 are reset. The baffles 30 protect the ends of the motor housing. During subsequent transport and processing, the second cleaning cylinder 26 is transported together with the motor housing to prevent wear on the ends of the motor housing during transport, which could affect its subsequent use. Furthermore, the support provided by the second cleaning cylinder 26 also prevents deformation of the motor housing during transport due to its thinness and the mutual compression between the individual motor housings.

[0056] Furthermore, when the motor housing is a barrel shape with only one open end, the corresponding second cleaning cylinder 26 can be replaced, so that the second cleaning cylinder 26 only has a baffle 30 at the bottom for protection, thus adapting to different working environments. The camera 24 can also perform image inspection of the motor housing. During the image inspection process, the corresponding second cleaning cylinder 26 can be rotated via the third electric rotating rod 33. As the second cleaning cylinder 26 rotates, the camera 24 can capture images of various positions on the motor housing, making the inspection more accurate. The camera 24 compares the captured images with preset images of qualified motor housings to determine whether the motor housing is qualified, ensuring product quality.
