Description
Technical Field
[0001] This application relates to the technical field of processing and manufacturing equipment, and particularly relates to a processing and forming device for a scratch-resistant and anti-aging window control switch. Background Art
[0002] An automotive window control switch is a device used inside a vehicle to control the raising and lowering of windows, usually located on the inner side of the door or on the console. It allows the driver and passengers to control the opening and closing of the windows with simple operations, providing convenience and comfort.
[0003] A scratch-resistant and anti-aging window control switch is a switch device designed to improve durability and extend service life, usually used to control the opening and closing of windows. The surface of this switch is specially treated to effectively resist scratching and wear, maintaining a clean and beautiful appearance. A scratch-resistant and anti-aging window control switch is usually integrally formed by an injection molding machine during the manufacturing process. Since a scratch-resistant and anti-aging window control switch requires the use of plastic materials with high heat resistance, wear resistance, and good electrical insulation properties, it is very difficult to reshape the formed window control switch. Therefore, high precision is required for injection molding. When a general injection mold is used for injection molding, since it needs to exhaust air through the parting surface, it is easy to cause defects such as flash and air bubbles in the product, thus having an adverse impact on the appearance and function of the product. Summary of the Utility Model
[0004] In order to improve the quality of products formed by mold injection molding, this application provides a processing and forming device for a scratch-resistant and anti-aging window control switch.
[0005] A processing and forming device for a scratch-resistant and anti-aging window control switch provided by this application adopts the following technical solutions:
[0006] A processing and forming device for a scratch-resistant and anti-aging window control switch includes a frame. A lower mold is arranged on the frame, and an upper mold is vertically slidably arranged above the lower mold. Cavities are formed on both the upper mold and the lower mold. A driving mechanism is arranged on the frame, and the driving mechanism is used to drive the upper mold to move. Under the action of the driving mechanism, the upper mold is closely attached to the lower mold. An air extraction mechanism is arranged on the lower mold, and the air extraction mechanism is used to extract air from the cavity after the upper mold and the lower mold are closed.
[0007] By adopting the above technical solutions, the driving mechanism is started to drive the upper mold to move, so that the upper mold and the lower mold are closely attached. Then, the air extraction mechanism extracts air from the cavity. When the air extraction mechanism evacuates the cavity to a vacuum, injection molding is carried out into the cavity, thus completing the injection molding work of the window control switch. Since the upper mold and the lower mold are closely attached and the cavity is in a vacuum, the probability of defects such as flash and air bubbles generated during injection molding of the window control switch is greatly reduced, ensuring the quality of the finished product.
[0008] Optionally, the driving mechanism includes:
[0009] Four guide rods, all of the four guide rods are arranged on the frame and in a vertical state. The four guide rods are evenly distributed around the lower mold with the lower mold as the center, and the upper mold is slidably mounted on the four guide rods.
[0010] A driving cylinder, which is arranged on the frame and the piston rod thereof is vertically downward and connected to the upper mold.
[0011] By adopting the above technical solution, first set the four guide rods and then install the upper mold on the four guide rods, so as to ensure the levelness of the upper mold and the stability during movement through the four guide rods. When the driving cylinder is started to drive the upper mold to move downward, the upper mold can stably and closely fit with the lower mold, reducing the probability of burrs generated in the cavity after the upper mold and the lower mold are closed during the injection molding work.
[0012] Optionally, the air extraction mechanism includes:
[0013] An air extraction pipe, an air outlet hole is opened on the inner side wall of the cavity of the lower mold. The air extraction pipe is arranged on the lower mold. One end of the air extraction pipe is located outside the lower mold, and the other end of the air extraction pipe extends into the lower mold and is communicated with the air outlet hole.
[0014] An air extraction pump, which is arranged at one end of the air extraction pipe outside the lower mold and is communicated with the inside of the air extraction pipe.
[0015] A closed-hole cover, which is horizontally slidably arranged on the lower mold and is located inside the cavity.
[0016] A moving component, which is arranged on the lower mold and is used to drive the closed-hole cover to move. The closed-hole cover closes the air outlet hole under the action of the moving component.
[0017] By adopting the above technical solution, use the moving component to move the closed-hole cover to open from the air outlet hole, then start the air extraction pump, and the air extraction pump extracts the air in the cavity through the air extraction pipe. When the air extraction pump evacuates the cavity, use the moving component to close the air outlet hole, thus completing the air extraction work in the cavity, and then the subsequent injection molding work can be carried out, reducing the probability of bubbles generated in the product during the subsequent injection molding.
[0018] Optionally, the moving component includes:
[0019] A moving rod, which is horizontally slidably arranged on the lower mold. One end of the moving rod is located outside the lower mold, and the other end of the moving rod is connected to the closed-hole cover.
[0020] A moving spring, which is arranged on the lower mold and is connected to the moving rod. The moving rod drives the closed-hole cover to cover the air outlet hole under the action of the moving spring.
[0021] By adopting the above technical solution, under normal circumstances, the moving rod drives the closing hole cover to cover the air outlet hole under the action of the moving spring. When it is necessary to pump air into or out of the cavity, the moving rod is pushed to compress the moving spring, so that the closing hole cover opens the air outlet hole, which is convenient, fast and has high working efficiency.
[0022] Optionally, a counterbore is formed on the inner side wall of the cavity of the lower mold. The counterbore is located on the periphery of the air outlet hole. When the closing hole cover is moved into the counterbore to block the air outlet hole, the surface of the closing hole cover is flush with the inner side wall of the cavity.
[0023] By adopting the above technical solution, a counterbore is formed at the air outlet hole. When the closing hole cover closes the air outlet hole, it enters the counterbore and the surface of the closing hole cover is flush with the inner side wall of the cavity. Thus, the probability that the closing hole cover interferes with the shape of the window control switch after injection molding is reduced, and the integrity of the shape of the window control switch after injection molding is ensured.
[0024] Optionally, a limiting component is arranged on the lower mold for limiting the position of the moving rod when the moving rod drives the closing hole cover to open the air outlet hole. The limiting component includes:
[0025] A limiting plate is arranged on the moving rod. A limiting groove is formed on the outer side wall of the lower mold. When the moving rod drives the closing hole cover to open the air outlet hole, the limiting plate is located in the limiting groove;
[0026] A limiting block, a horizontal sliding groove is formed on the inner side wall of the limiting groove, and the limiting block is slidably installed on the limiting groove;
[0027] A limiting spring is arranged on the sliding groove and connected with the limiting block. The limiting block partially penetrates out of the sliding groove under the action of the limiting spring and abuts against the limiting plate.
[0028] By adopting the above technical solution, the limiting block is extruded so that the limiting block compresses the limiting spring and moves until the whole limiting block moves into the sliding groove. Then, the moving rod can be moved to open the air outlet hole by the closing hole cover. The limiting plate moves into the limiting groove along with the moving rod. After the limiting rod enters the limiting groove, the limiting block is released. The limiting block partially penetrates out of the sliding groove under the action of the limiting spring and abuts against the limiting plate. Thus, by limiting the limiting plate in the limiting groove, the fixing work of the position of the moving rod is realized. When the air extraction pump is working, it is not necessary for the staff to always hold the moving rod to maintain the position of the closing hole cover, reducing the working intensity; when the air extraction pump finishes extracting air and it is necessary to close the closing hole cover, the limiting block is extruded to enter the sliding groove again, and the moving rod drives the limiting plate to move out of the limiting groove under the action of the moving spring.
[0029] Optionally, an arc-shaped guiding surface is formed on the side wall of the part of the limiting block extending out of the sliding groove close to the opening of the limiting groove.
[0030] By adopting the above technical solution, an arc-shaped guiding surface is formed on the side wall of the part of the limiting block extending outside the sliding groove near the opening of the limiting groove. When the limiting plate is moved into the limiting groove, the limiting plate first contacts the guiding surface, and the guiding surface generates a component force that drives the limiting block into the sliding groove, so that there is no need to manually squeeze the limiting block into the sliding groove, simplifying the working steps and improving the working efficiency.
[0031] In summary, the present application includes at least one of the following beneficial technical effects:
[0032] 1. The driving mechanism is started to drive the upper mold to move, so that the upper mold and the lower mold are closely attached. Then, the air extraction mechanism is used to extract air from the cavity. When the air extraction mechanism evacuates the cavity, injection molding is carried out into the cavity, thus completing the injection molding work of the window control switch. Since the upper mold and the lower mold are closely attached and the cavity is vacuum, the probability of defects such as burrs and bubbles generated in the injection molding of the window control switch is greatly reduced, ensuring the quality of the finished product.
[0033] 2. By forming a countersunk hole at the air outlet, when the closing hole cover closes the air outlet, it enters the countersunk hole and the surface of the closing hole cover is flush with the inner side wall of the cavity, thus reducing the probability that the closing hole cover interferes with the shape of the window control switch after injection molding in the subsequent injection molding work, ensuring the integrity of the shape of the window control switch after injection molding.
[0034] 3. By adopting the above technical solution, an arc-shaped guiding surface is formed on the side wall of the part of the limiting block extending outside the sliding groove near the opening of the limiting groove. When the limiting plate is moved into the limiting groove, the limiting plate first contacts the guiding surface, and the guiding surface generates a component force that drives the limiting block into the sliding groove, so that there is no need to manually squeeze the limiting block into the sliding groove, simplifying the working steps and improving the working efficiency.

Detailed implementation manner
[0039] The following further elaborates on this application Figure 1 - with reference to the attached Figure 3 drawings for a more detailed description.
[0040] The embodiment of this application discloses a processing and forming device for an anti-scratch and anti-aging window control switch.
[0041] Referring to Figure 1 , the processing and forming device for an anti-scratch and anti-aging window control switch includes a frame 1. A lower mold 12 is arranged on the frame 1, and an upper mold 13 is vertically slidably arranged above the lower mold 12. Cavities 14 are provided on both the upper mold 13 and the lower mold 12. A drive mechanism 2 is arranged on the frame 1, and the drive mechanism 2 is used to drive the upper mold 13 to move. The upper mold 13 is tightly attached to the lower mold 12 under the action of the drive mechanism 2. An air extraction mechanism 3 is arranged on the lower mold 12 for extracting air from the cavity 14 after the upper mold 13 and the lower mold 12 are closed.
[0042] Referring to Figure 1 , the drive mechanism 2 includes four guide rods 21 and a drive cylinder 22. The four guide rods 21 are all fixedly installed on the frame 1 and are evenly distributed around the lower mold 12 with the lower mold 12 as the center. The four guide rods 21 are all arranged in a vertical state. The upper mold 13 is vertically slidably installed on the four guide rods 21. The drive cylinder 22 is fixedly installed on the frame 1 above the upper mold 13, and the piston rod is vertically downward and fixedly connected to the upper surface of the upper mold 13. The four guide rods 21 ensure the levelness of the upper mold 13 and its stability during movement, so that when the drive cylinder 22 is started to drive the upper mold 13 to move downward, the upper mold 13 can stably and tightly fit with the lower mold 12, reducing the probability of burrs generated in the cavity 14 during the injection molding work after the upper mold 13 and the lower mold 12 are closed.
[0043] Referring to Figure 1 and Figure 2, the air extraction mechanism 3 includes an air extraction pipe 31, an air extraction pump 32, a closed hole cover 33 and a moving component 34. A horizontal air outlet hole 35 is formed on the inner side wall of the cavity 14 of the lower mold 12. The air extraction pipe 31 is fixedly installed on the outer side wall of the lower mold 12. One end of the air extraction pipe 31 is connected to the air outlet hole 35, and the other end of the air extraction pipe 31 extends outside the lower mold 12. The air extraction pump 32 is fixedly installed at one end of the air extraction pipe 31 located outside the lower mold 12. The air extraction pump 32 extracts air from the inside of the cavity 14 of the lower mold 12 through the air extraction pipe 31.
[0044] Refer to Figure 2 and Figure 3 , the closed hole cover 33 is horizontally slidably installed on the lower mold 12 through the moving component 34. A countersunk hole 36 is formed at the air outlet hole 35 of the lower mold 12. When the closed hole cover 33 is integrally clamped into the countersunk hole 36 under the action of the moving component 34, the closed hole cover 33 closes the air outlet hole 35 and at the same time the surface of the closed hole cover 33 close to the cavity 14 is flush with the inner side wall of the lower mold 12.
[0045] Refer to Figure 2 and Figure 3 , the moving component 34 includes a moving rod 37 and a moving spring 38. The moving rod 37 is horizontally slidably installed on the side wall of the lower mold 12. One end of the moving rod 37 is located outside the lower mold 12, and the other end of the moving rod 37 extends into the cavity 14 of the lower mold 12 and is fixedly connected to the closed hole cover 33. The moving spring 38 is fixedly installed on the lower mold 12 and is connected to the moving rod 37. The moving rod 37 drives the closed hole cover 33 to close the air outlet hole 35 under the action of the moving spring 38..
[0046] Refer to Figure 1 and Figure 3 , the driving cylinder 22 is started to drive the upper mold 13 to move, so that the upper mold 13 and the lower mold 12 are closely attached, and the moving rod 37 is moved to compress the moving spring 38, thereby driving the closed hole cover 33 to open the air outlet hole 35.
[0047] Refer to Figure 2 and Figure 3 , and then the air in the cavity 14 is extracted through the air extraction pump 32. When the air extraction pump 32 evacuates the cavity 14, the moving rod 37 is released, and the moving rod 37 drives the closed hole cover 33 to close the air outlet hole 35 under the action of the moving spring 38. Then, injection molding is carried out into the cavity 14, thus completing the injection molding work of the window control switch.
[0048] Refer to Figure 2 and Figure 3, a limiting component 4 for limiting the position of the moving rod 37 when the closing hole cover 33 is driven by the moving rod 37 to open the air outlet hole 35 is arranged on the lower die 12. The limiting component 4 includes a limiting plate 41, a limiting block 42 and a limiting spring 43. The limiting plate 41 is fixedly installed at one end of the moving rod 37 located outside the lower die 12. A horizontal limiting groove 44 is formed on the outer side wall of the lower die 12. When the moving rod 37 drives the closing hole cover 33 to open the air outlet hole 35, the limiting plate 41 enters the limiting groove 44.
[0049] Refer to Figure 2 and Figure 3 , a horizontal sliding groove 45 is formed on the inner side wall of the limiting groove 44. The limiting block 42 is slidably installed on the sliding groove 45. The limiting spring 43 is fixedly installed on the inner bottom wall of the sliding groove 45 and fixedly connected to the limiting block 42. The limiting block 42 partially penetrates out of the sliding groove 45 under the action of the limiting spring 43 and abuts against the limiting plate 41. An arc-shaped guiding surface 46 is formed on one side wall of the part of the limiting block 42 extending out of the sliding groove 45 close to the opening of the limiting groove 44.
[0050] Refer to Figure 2 and Figure 3 , when the moving rod 37 is moved to make the closing hole cover 33 open the air outlet hole 35, the limiting plate 41 moves into the limiting groove 44 along with the moving rod 37. The limiting plate 41 first contacts the guiding surface 46, and the guiding surface 46 will generate a component force for driving the limiting block 42 to move into the sliding groove 45. Until the whole limiting plate 41 enters the limiting groove 44 and separates from the limiting block 42, the limiting block 42 partially penetrates out of the sliding groove 45 under the action of the limiting spring 43 and abuts against the limiting plate 41. Thus, the limiting block 42 is limited in the limiting groove 44 through the limiting plate 41, realizing the fixing work of the position of the moving rod 37, so that when the air extraction pump 32 is performing the air extraction work, there is no need for the staff to always hold the moving rod 37 to maintain the position of the closing hole cover 33, reducing the working intensity; when the air extraction of the air extraction pump 32 is completed and the closing hole cover 33 needs to be closed, the limiting block 42 is extruded to enter the sliding groove 45 again, and the moving rod 37 drives the limiting plate 41 to move out of the limiting groove 44 under the action of the moving spring 38.
[0051] The working principle of the embodiment of the present application is:
[0052] The driving cylinder 22 is activated to drive the upper mold 13 to move, so that the upper mold 13 and the lower mold 12 are closely attached. The moving rod 37 is moved to compress the moving spring 38, thereby driving the closing cover 33 to open the air outlet hole 35. Then, the cavity 14 is evacuated by the air extraction pump 32. When the air extraction pump 32 evacuates the cavity 14 to a vacuum state, the moving rod 37 drives the closing cover 33 to close the air outlet hole 35 under the action of the moving spring 38. Then, injection molding is carried out into the cavity 14, thus completing the injection molding work of the window control switch. Since the upper mold 13 and the lower mold 12 are closely attached and the cavity 14 is in a vacuum state, the probability of defects such as burrs and bubbles generated in the injection molding of the window control switch is greatly reduced, ensuring the quality of the finished product.
[0053] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
