[0002] With the development of the automobile industry, safety, energy saving, environmental protection, intelligence and information are the development trends of future automobiles, especially the development of new models, improvement of automobile performance, and the stability of various detection and feedback devices. The camshaft position sensor is an important electrical component on the engine, and its sealing and assembly have corresponding technical requirements. The sensor housing is a plastic part that is usually processed and produced by injection molding. The working principle is to inject the heated and melted plastic material into the mold cavity by high pressure, and after cooling and solidification, a plastic product with the same shape as the mold cavity is obtained. The injection molding of the housing is designed according to the specific size, shape and functional requirements of the camshaft sensor housing.

[0003] The camshaft sensor housing is molded by high-temperature cooling and solidification during injection molding. After cooling and solidification, the molded housing is easy to fit tightly on the module of the mold cavity and is difficult to remove.

The top of the bevel scraper is fixedly connected with a piercing rod. The moving bevel scraper is limited by arranging a piercing rod that penetrates the connecting long plate on the top of the bevel scraper to prevent the bevel scraper elastically connected to the push spring from being affected by the thrust when it is in friction contact with the top surface of the lower mold, causing the push spring to twist and tilt, affecting the cleaning effect. The side of the connecting long plate away from the cavity cleaning mechanism is slidably connected to the inner side of the electric slide rail.

[0023] When the circular top block moves down to the top surface flush with the top surface of the annular module, it stops and seals the annular module, so as to prevent a large amount of injection molding material from pouring into the annular module and causing the injection molding shape of the outer shell to change and become difficult to use.

[0024] 3. The present invention provides a cleaning device, and the bevel scraper performs scraping cleaning on the top surface of the lower mold when it moves, so as to prevent excessive residual slag from gradually accumulating on the top surface of the lower mold after multiple shell molding operations, affecting the sealing and clamping effect of the lower mold and the upper mold; a piercing rod that penetrates the connecting long plate is provided on the top of the bevel scraper to limit the moving bevel scraper, so as to prevent the bevel scraper elastically connected to the push spring from being affected by the thrust when it is in friction contact with the top surface of the lower mold, causing the push spring to twist and tilt, affecting the cleaning effect; when the push spring is compressed, the pushing force on the bevel scraper is increased to make it tightly contact with the top surface of the lower mold, so as to prevent the bevel scraper from encountering attached convex block-shaped slag when moving, and the bevel scraper is slightly moved upward through the elastic connection to pass over the slag, which is difficult to clean; a bottom circular groove is provided at the bottom of the connecting long plate to facilitate the storage of the compressed push spring, so as to prevent the push spring from being gradually compressed to the contraction limit and gradually losing its elastic performance when it is in a fully compressed state for a long time, affecting its use.

[0052] The cavity cleaning mechanism 802 includes a receiving circular plate 8021, the top of the receiving circular plate 8021 is fixedly connected to a driving motor 8022, the driving shaft of the driving motor 8022 is fixedly connected to a linkage circular plate 8023, the bottom of the linkage circular plate 8023 is fixedly connected to a grinding block 8024, the bottom of the linkage circular plate 8023 is fixedly connected to a triangular scraper rod 8025, the bottom of the linkage circular plate 8023 is fixedly connected to an arc-shaped inclined rod 8026, the outer side of the receiving circular plate 8021 is fixedly connected to one side of the connecting long plate 801, the top of the linkage circular plate 8023 is rotatably connected to the bottom of the receiving circular plate 8021 through a rotating bolt, and three arc-shaped inclined rods 8026 are provided, and the three arc-shaped inclined rods 8026 are distributed at the bottom of the linkage circular plate 8023 near the outer When in use, after the forming shell is removed from the annular module 12, the electric slide rail 5 drives the connecting long plate 801 to drive some of the cavity cleaning mechanisms 802 to move together. When the connecting long plate 801 moves to the top of the lower mold 3, the electric telescopic rod 6 drives the annular slide rail so that the connecting long plate 801 drives the bottom push spring 804 and the bevel scraper 805 to move downward. The bevel scraper 805 moves down and stops when it contacts the top surface of the lower mold 3. At this time, the electric slide rail 5 continues to drive the connecting long plate 801 and the bevel scraper 805 to move. When the bevel scraper 805 moves, it scrapes and cleans the top surface of the lower mold 3. A top-penetrating rod 806 that penetrates the connecting long plate 801 is set on the top of the bevel scraper 805 to control the moving bevel scraper 80 5 is limited, and the push spring 804 is compressed when the connecting long plate 801 is pressed down. When the push spring 804 is compressed, the push force on the bevel scraper 805 is increased to make it tightly contact with the top surface of the lower mold 3. When the cavity cleaning mechanism 802 moves to the top of the annular module 12, it can stop moving, and the electric telescopic rod 6 drives the electric slide rail 5 to move down again so that the connecting long plate 801 moves down together. When the connecting long plate 801 moves down, it continues to compress the push spring 804 and drives the cavity cleaning mechanism 802 to move down into the lower mold cavity 10. By opening a bottom circular groove 803 at the bottom of the connecting long plate 801, it is convenient to store the compressed push spring 804. When the connecting long plate 801 drives the receiving circular plate 8021 to move to the top of the annular module 12, the electric slide rail 5 drives the receiving circular plate 8021 to move downward, and the receiving circular plate 8021 moves downward to drive the linkage disc 8023, the grinding block 8024, the triangular scraper 8025 and the arc-shaped inclined rod 8026 at the bottom to move downward together. When the grinding block 8024 and the triangular scraper 8025 move downward to the bottom surface and contact the top surface of the annular module 12, the arc-shaped inclined rod 8026 just moves downward to the bottom surface and contacts the bottom of the inner wall of the lower mold cavity 10. At this time, the driving motor 8022 is started to drive the linkage disc 8023 to rotate. When the linkage disc 8023 rotates, it drives the grinding block 8024, the triangular scraper 8025 and the arc-shaped inclined rod 8026 at the bottom to rotate together. When the grinding block 8024 rotates, the bottom surface is always in contact with the top surface of the annular module 12 and grinds the top surface of the annular module 12.When the triangular scraper 8025 rotates, it scrapes the residual slag cleaned by the grinding block 8024 and pushes it out of the annular module 12. When the arc-shaped inclined rod 8026 rotates, the outer surface is always in contact with the inner wall of the lower mold cavity 10. As the linkage disc 8023 rotates, the arc-shaped inclined rod 8026 scrapes and cleans the inner wall of the lower mold cavity 10. When the arc-shaped inclined rod 8026 rotates, its inclined surface setting pushes the scraped residual slag upward and discharges it from the lower mold cavity 10.

[0053] When the present invention is operated and used, the lower mold 3 is pushed downward by the hydraulic push rod 2 to fit with the upper mold 1 for film closing, and then the molten plastic material is injected into the mold cavity from the injection hole to fill the mold cavity. After the injection molding material between the upper mold 1 and the lower mold 3 is cooled and formed, the upper mold 1 is driven by the hydraulic push rod 2 to move upward and demold the lower mold 3. At this time, the molding shell on the annular module 12 can be ejected by top punching through the unloading device 7. After the material is ejected, the cleaning device 8 is driven by the electric slide rail 5 to move on the lower mold 3. When the cleaning device 8 moves, the surface of the lower mold 3 can be scraped and cleaned. When it moves to the middle position of the lower mold 3, the electric telescopic rod 6 drives the electric slide rail 5 to move the cleaning device 8 downward. At this time, the cleaning device 8 can The inner wall of the mold cavity of the mold 3 is cleaned. After cleaning, the electric slide rail 5 is driven by the electric telescopic rod 6 to drive the cleaning device 8 to move above the lower mold 3. The cleaning device 8 is driven by the electric slide rail 5 to move to the positions on both sides of the lower mold 3. When it is necessary to unload the formed shell on the annular module 12, the circular top block 703 is pushed upward by the electric push rod 701. When the circular top block 703 moves upward, the formed shell on the annular module 12 is top-punched and unloaded. When the circular top block 703 moves upward, the outer oblique ring plate 704 at the bottom is driven to move upward together. When the outer oblique ring plate 704 moves upward, the residual slag that accidentally falls into the annular module 12 and is located between the circular top block 703 and the outer oblique ring plate 704 is discharged outward through its inclined surface. The outer oblique ring plate 704 moves upward When the molding shell is removed from the annular module 12, the electric slide rail 5 drives the connecting long plate 801 to drive some of the cavity clearing mechanisms 802 to move together. When the connecting long plate 801 moves to the top of the lower mold 3, the annular slide rail is driven by the electric telescopic rod 6 so that the connecting long plate 801 drives the bottom push spring 804 and the bevel scraper 805 to move downward. When the side scraper 805 moves down to contact with the top surface of the lower mold 3, it can stop. At this time, the electric slide rail 5 continues to drive the connecting long plate 801 and the bevel scraper 805 to move. When the bevel scraper 805 moves, the top surface of the lower mold 3 is scraped and cleaned. A penetration rod 806 that penetrates the connecting long plate 801 is set on the top of the bevel scraper 805 to limit the moving bevel scraper 805. When the connecting long plate 801 is pressed down, the pushing spring 804 is compressed. When the pushing spring 804 is compressed, the pushing force on the bevel scraper 805 is increased to make it tightly contact with the top surface of the lower mold 3. When the cavity cleaning mechanism 802 moves to the top of the annular module 12, it can stop moving, and the electric slide rail 5 is driven downward again by the electric telescopic rod 6 to make the connecting long plate 801 move downward together.When the connecting long plate 801 moves downward, it continues to compress the push spring 804 and drives the cavity cleaning mechanism 802 to move downward into the lower mold cavity 10. By opening a bottom circular groove 803 at the bottom of the connecting long plate 801, the compressed push spring 804 is stored. When the connecting long plate 801 drives the receiving circular plate 8021 to move to the top of the annular module 12, the receiving circular plate 8021 is driven downward by the electric slide rail 5. The receiving circular plate 8021 moves downward and drives the linkage disc 8023, the grinding block 8024, the triangular scraper rod 8025 and the arc-shaped inclined rod 8026 at the bottom to move downward together. When the grinding block 8024 and the triangular scraper rod 8025 move down to the bottom surface and contact the top surface of the annular module 12, the arc-shaped inclined rod 8026 just moves down to the bottom surface and contacts the bottom of the inner wall of the lower mold cavity 10. At this time, the driving electric The machine 8022 drives the linkage disc 8023 to rotate. When the linkage disc 8023 rotates, it drives the grinding block 8024, the triangular scraper rod 8025 and the arc-shaped inclined rod 8026 at the bottom to rotate together. When the grinding block 8024 rotates, the bottom surface is always in contact with the top surface of the annular module 12 and grinds the top surface of the annular module 12. When the triangular scraper rod 8025 rotates, it scrapes off the residual slag cleaned by the grinding block 8024 and pushes it out of the outer side of the annular module 12. When the arc-shaped inclined rod 8026 rotates, the outer surface is always in contact with the inner wall of the lower mold cavity 10. As the linkage disc 8023 rotates, the arc-shaped inclined rod 8026 scrapes and cleans the inner wall of the lower mold cavity 10. When the arc-shaped inclined rod 8026 rotates, its inclined surface setting pushes the scraped residual slag upward and discharges it from the lower mold cavity 10.
