Description

Technical Field

[0001] The invention relates to the field of automobile interior decoration injection molding, and more specifically to an on-vehicle gear shift control center control injection molding mold. Background Art

[0002] The vehicle-mounted gear shift control center control injection mold is an injection mold used to produce the internal gear shift control center control components of the car.

[0003] In order to solve the problem of frequent replacement of the injection mold of the automobile center control panel due to loose fit of the male or female mold plate, the prior art (Chinese invention patent with announcement number CN115091705B) discloses an injection mold of the center control panel, which designs a structure for fixing the mold core by horizontal clamping. Although it can reduce the axial wear of the injection mold and realize the quick disassembly and assembly of the injection mold, the following problems still exist during the use of the mold:

[0004] During the use of the mold, dust and metal powder formed by mold friction accumulate and enter the gap between the ejector pin and the ejector pin tunnel, causing the gap between the mating surfaces to become smaller and smaller and the smoothness to become lower and lower, resulting in the ejector pin being completely burned and stuck until it breaks. Although the risk of the ejector pin being stuck and broken can be reduced by applying lubricating oil to the outer surface of the ejector pin, the lubricating oil can only support a period of time after application. If the mold needs to be used for long-term injection molding production, it is also necessary to shut down the machine regularly, remove the mold, and clean and lubricate the ejector pin, which delays the production progress and makes the upper and lower molds and the mold ejector pins more troublesome to maintain. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) In this scheme, a descaling component and a lubrication part are provided. When the ejector pushes the ejector plate and the ejector pin toward the movable mold, the rack can drive the gear 1 and the worm 1 to rotate. The rotation of the worm 1 drives the worm gear 1 and the circular scraper to rotate. The rotating circular scraper can make all-round contact with the outer surface of the ejector pin, clean the surface dirt more evenly, and bring greater scraping force through its rotational motion. For more stubborn dirt, oil or residue, the rotational motion can enhance the cleaning effect, ensure that the surface of the ejector pin is cleaner, avoid concentrating the action on a certain point, disperse the stress during scraping, reduce possible scratches or wear on the surface of the ejector pin, realize automatic cleaning of the dirt on the outer surface of the ejector pin, avoid the ejector pin carrying dirt into the gap when entering the movable mold, and extend the action time of the lubricant. The lubrication part sprays the lubricant on the cleaned ejector pin to realize automatic lubrication. This design can realize cleaning and lubrication of the ejector pin without disassembling the mold. At the same time, the ejector pin can be cleaned and lubricated during the injection molding process of the mold, thereby improving the production efficiency of the mold and saving human resources.

[0021] (2) In this scheme, an oil thin coating component is set up, and the rack can drive the worm gear 2 and the worm wheel 2 to rotate, thereby driving the bristles 2 to rotate and brush the lubricating oil on the outer surface of the ejector pin evenly, and then the lubricating oil is evenly scraped by the oil scraper. On the one hand, it can avoid the situation where the lubricating oil is sprayed on the outer surface of the ejector pin and directly scraped off by the oil scraper, which may cause the oil scraper to directly scrape off most of the lubricating oil, especially when the lubricating oil is not sprayed evenly, resulting in insufficient lubricating oil in some areas, affecting the lubrication effect. On the other hand, the oil scraper can effectively control the thickness of the lubricating oil and ensure that the lubricating oil forms an appropriate coating on the surface of the ejector pin, which can achieve the lubrication effect without excessive application of the lubricating oil to contaminate the product. At the same time, the rotation of the oil scraper during the oil scraping process can reduce scratches or stripes formed on the surface of the ejector pin, ensuring the smoothness and continuity of the lubricating paste layer. The rotating action will make the pressure of the contact between the edge of the scraper and the surface of the ejector pin more uniform, which helps to form a smooth coating.

[0022] (3) In this scheme, a metal ring and a friction plate are provided. When the worm gear rotates to drive the hollow disk body to rotate, the friction plate can contact the inner surface of the metal ring, thereby generating heat. The heat is transferred to the scraper through the heat conductive plate, thereby heating the lubricant on the outer surface of the scraper and the ejector pin. The heated lubricant usually has better fluidity and can cover the ejector pin surface more evenly to form a consistent lubricating film. At the same time, after the lubricant is properly heated, its adhesion ability may be enhanced, and a stronger lubricating film can be formed on the ejector pin surface. The formed film may be more durable, thereby extending the effective time of the lubricant and reducing the need for frequent application. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The hollow casing 621 is also connected to a lubrication part 7, and the lubrication part 7 includes an input port 71 opened at the upper end of the hollow casing 621, a nozzle head 74 fixed to the inner wall of the hollow casing 621 and connected to the input port 71, an oil drain groove 73 opened in the nozzle head 74 and the hollow casing 621, and an oil drain port 72 opened at the lower end of the hollow casing 621 and connected to the oil drain groove 73.

[0045] By adopting the above technical solution, the positioning plate 1 is fixed on the moving plate of the injection molding machine, and the fixed mold 4 is fixed on the inner wall of the injection molding machine. The injection molding machine drives the moving plate to move and drives the positioning plate 1 and the movable mold 3 to move toward the fixed mold 4 to perform mold closing and injection molding. After the injection molding is completed, the movable mold 3 is separated from the fixed mold 4, and the injection molding machine drives the moving plate to drive the positioning plate 1 and the movable mold 3 to move in the direction opposite to the fixed mold 4. One side of the ejector rod 53 contacts the ejector seat on the inner wall of the injection molding machine, and the ejector seat pushes the ejector rod 53 and the ejector plate 52 to move in the direction of the movable mold 3. The movement of the ejector plate 52 drives multiple ejector pins 54 to move, and the formed product in the male mold core of the movable mold 3 is ejected. 2 can also drive the rack 614 to move, and the movement of the rack 614 can drive the gear 612 and the worm 613 to rotate, and the rotation of the worm 613 drives the worm wheel 623 to rotate, and the rotation of the worm wheel 623 drives the circular scraper 624 to rotate. The rotating circular scraper 624 can make all-round contact with the outer surface of the ejector pin 54, clean the surface dirt more evenly, and can bring greater scraping force through its rotating motion. For more stubborn dirt, oil or residue, the rotating motion can enhance the cleaning effect, ensure that the surface of the ejector pin 54 is cleaner, and can also avoid concentrating on a certain point, dispersing the stress during scraping. , reducing possible scratches or wear on the surface of the ejector pin 54, realizing automatic cleaning of dirt on the outer surface of the ejector pin 54, preventing the ejector pin 54 from carrying dirt into the gap when entering the movable mold 3, and extending the action time of the lubricating oil. At the same time, the rotation of the worm gear 1 623 can also drive the tooth key 1 631, the gear 2 632 and the gear 3 633 to rotate. When the gear 3 633 rotates, it drives the scraper 634 to rotate. The scraper 634 moves along the descaling inclined surface 625 to scrape off the dirt on the descaling inclined surface 625. After the dirt is scraped off by the scraper 634, it is discharged through the descaling groove 635, avoiding excessive dirt accumulation on the descaling inclined surface 625 to affect the cleaning of the circular scraper 624 The lubricating oil is pumped into the nozzle head 74 through the input port 71, and the lubricating oil is sprayed out from the nozzle head 74 and sprayed on the outer surface of the ejector pin 54. The lubricating oil dripping from the outer surface of the ejector pin 54 and the lubricating oil remaining on the inner wall of the nozzle head 74 enter the oil discharge groove 73 and are discharged from the oil discharge port 72. The lubricating unit 7 sprays the lubricating oil on the cleaned ejector pin 54 to realize automatic lubrication. This design can realize the cleaning and lubrication of the ejector pin 54 without disassembling the mold. At the same time, the ejector pin 54 can be cleaned and lubricated during the mold injection process, thereby improving the production efficiency of the mold and saving human resources.

[0046] like Fig. 9 - Fig.10 As shown, the fixed mold 4 is also connected to an oil thin coating component 8, and the oil thin coating component 8 includes a worm 88 rotatably connected to the movable mold 3, two gears 89 fixedly connected to both ends of the worm 88, a worm wheel 81 rotatably connected to the movable mold 3 and transmission-connected to the worm 88, a brush 82 fixedly connected to the inner wall of the worm wheel 81, a hollow disk 83 fixedly connected to one side of the worm wheel 81, and an oil scraper 84 fixedly connected to the inner wall of the hollow disk 83, and the two gears 89 are respectively meshed with the two racks 614.

[0047] By adopting the above technical solution, the rack 614 can drive the gear 6 89 and the worm 2 88 to rotate while moving toward the inside of the movable mold 3. The rotation of the worm 2 88 drives the worm wheel 2 81 to rotate. The rotation of the worm wheel 2 81 drives the brush 2 82, the hollow disk 83 and the scraper 84 to rotate. The rotation of the brush 2 82 can brush the lubricating oil on the outer surface of the ejector 54 to various areas of the outer surface of the ejector 54, and then the lubricating oil is evenly scraped by the scraper 84. On the one hand, it can avoid the situation that the lubricating oil is sprayed on the outer surface of the ejector 54 and directly scraped off the oil, resulting in the scraper 84 directly scraping off most of the lubricating oil. Especially when the lubricating oil is not sprayed evenly, some areas may be short of lubricating oil, which affects the lubrication effect. On the other hand, the scraper 84 can effectively control the thickness of the lubricating oil and ensure that the lubricating oil forms an appropriate coating on the surface of the ejector pin 54, which can achieve the lubrication effect without excessive application of the lubricating oil and contaminating the product. At the same time, the rotation of the scraper 84 during the scraping process can reduce the scratches or stripes formed on the surface of the ejector pin 54, ensuring the smoothness and continuity of the lubricating paste layer. The rotating action can make the pressure between the edge of the scraper 84 and the surface of the ejector pin 54 more uniform, which helps to form a smooth coating.

[0048] like Fig. 9 - Fig.13 As shown, a heat conductive sheet 87 is fixedly connected to the inside of the hollow disk 83, and one end of the heat conductive sheet 87 penetrates into the inside of the scraper 84, and the other end of the heat conductive sheet 87 is connected to a friction sheet 86. A metal ring 85 is fixedly connected to the inside of the movable mold 3, and the inner wall of the metal ring 85 is in sliding contact with the friction sheet 86.

[0049] The heat conducting plate 87 has two symmetrical movable grooves 871 and a mounting groove 872 located between the two movable grooves 871, and a second spring 862 is placed in the mounting groove 872. The two ends of the second spring 862 are respectively connected to the inner wall of the mounting groove 872 and one side of the friction plate 86, and two symmetrical columns 861 are fixedly connected to one side of the friction plate 86. The two columns 861 are respectively movably inserted in the two movable grooves 871.

[0050] By adopting the above technical solution, while the worm gear 81 rotates to drive the hollow disk 83 to rotate, the friction plate 86 can contact the inner surface of the metal ring 85, thereby generating heat. The heat is transferred to the scraper 84 through the heat conductive plate 87, and the lubricant on the outer surface of the scraper 84 and the ejector pin 54 is heated. The heated lubricant usually has better fluidity and can cover the surface of the ejector pin 54 more evenly to form a consistent lubricating film. At the same time, after the lubricant is properly heated, its adhesion ability may be enhanced, and a stronger lubricating film can be formed on the surface of the ejector pin 54. The formed film may be more durable, thereby extending the effective time of the lubricant and reducing the need for frequent application. The spring 862 can apply a force to the friction plate 86, so that one side of the friction plate 86 is always in contact with the inner wall of the metal ring 85, thereby avoiding the wear of the friction plate 86 and the inability of the friction plate 86 to contact the metal ring 85.

[0051] like Figure 7 As shown, the interior of the hollow sleeve 621 is also connected to a roughness reducing and moisturizing portion 65, and the roughness reducing and moisturizing portion 65 includes a tooth key 2 651 integrally formed on the other side of the worm gear 1 623, a gear 4 652 rotatably connected to the interior of the hollow sleeve 621 and meshing with the tooth key 2 651, a gear 5 653 rotatably connected to the interior of the hollow sleeve 621 and meshing with the gear 4 652, a plurality of arc plates 654 fixedly connected to the inner wall of the gear 5 653, and sandpaper fixedly connected to the inner wall of the arc plate 654.

[0052] By adopting the above technical solution, the rotation of the worm gear 1 623 drives the tooth key 2 651 to rotate, the rotation of the tooth key 2 651 drives the gear 4 652 and the gear 5 653 to rotate, the rotation of the gear 5 653 drives the multiple arc plates 654 and the sandpaper to rotate, the sandpaper contacts the outer surface of the ejector pin 54, and grinds the outer surface of the ejector pin 54 that has been cleaned by the circular scraper 624 and not sprayed with oil, removes the tiny protrusions and unevenness on the surface of the ejector pin 54, and makes the surface smoother and flatter, thereby improving the adhesion of the lubricating oil, and the lubricating oil can be more evenly covered on the surface to form a stable lubricating film, and can also remove the oxide layer, rust or other impurities on the surface of the ejector pin 54, ensuring that the lubricating oil is in direct contact with the metal surface, improving the lubrication effect and protection ability, and at the same time reducing the roughness of the surface of the ejector pin 54, reducing the friction between the ejector pin 54 and the mold during work, thereby reducing wear and extending the service life of the ejector pin 54.

The rotation of the bristles 82 can brush the lubricating oil on the outer surface of the ejector pin 54 to various areas of the outer surface of the ejector pin 54, and then the lubricating oil is evenly scraped by the scraper 84. While the rotation of the worm gear 81 drives the hollow disk 83 to rotate, the friction plate 86 can contact the inner surface of the metal ring 85, thereby generating heat. The heat is transferred to the scraper 84 through the heat conductive sheet 87, and the lubricant on the outer surface of the scraper 84 and the ejector pin 54 is heated. The heated lubricant usually has better fluidity.
