Description

Technical Field

[0001] The invention belongs to the technical field of plastic product production, and in particular relates to a mold cleaning device used for plastic product production. Background Art

[0002] Plastic products are generally processed and formed by injection molds. Due to the high viscosity of liquid plastic, even with the use of lubricating oil, some plastic often remains and adheres to the inside of the injection hole of the mold. Therefore, the mold needs to be cleaned regularly.

[0003] At present, the Chinese invention with the publication number of CN113477619B discloses a mold cleaning device, including a first processing chamber and a second processing chamber, wherein a first processing device is arranged in the first processing chamber, a soaking tank is arranged in the second processing chamber, a second processing device is arranged at one end of the soaking tank close to the first processing chamber, and a third processing device is arranged on the bottom surface of the tank cavity at one end of the soaking tank away from the second processing device; a conveying device is arranged around the first processing device and the second processing device, and a clamping mechanism is arranged on the conveying device; the conveying device is located at one end of the second processing chamber lower than one end of the first processing chamber; a transfer device is arranged on the side of the first processing chamber away from the second processing chamber and directly above the conveying device. The invention provides a mold cleaning device, which can clean the mold in batches in steps, clean more thoroughly, shorten the drying time after mold cleaning, and will not damage the mold, which is very suitable for cleaning molds.

[0004] Common mold cleaning includes ultrasonic cleaning machines, which can effectively clean small injection holes that cannot be touched by humans. However, existing ultrasonic cleaning machines generally put the mold into the ultrasonic cleaning liquid for direct cleaning. Although the plastic residues and other impurities and dust accumulated inside the mold can be cleaned and peeled off, these plastic residues and dust impurities will fall directly into the ultrasonic cleaning liquid. Not only is it difficult to clean these things out, but they will also contaminate the clean ultrasonic cleaning liquid, making it very turbid. There are a lot of impurities and dirt inside, making it difficult to use multiple times, so it is relatively wasteful and the cost of cleaning the mold is high. Summary of the invention

[0005] The object of the present invention is to provide a mold cleaning device for the production of plastic products, which has the advantage of facilitating the filtering of impurities and dust cleaned from the mold, so that the cleaning liquid in the ultrasonic machine can be reused multiple times.

[0006] The above technical purpose of the present invention is achieved through the following technical scheme: a mold cleaning device for the production of plastic products, including a cleaning box, the interior of the cleaning box is slidably connected to a lifting water tank, one side of the top of the cleaning box is fixedly connected to a support column, the cleaning box and the support column are internally rotatably connected by a bidirectional screw, a servo motor with an output end fixedly connected to the bidirectional screw is installed on the top of the support column, and a positioning mechanism and a filtering mechanism used in conjunction with the lifting water tank are respectively installed on the top and inside of the cleaning box.

[0007] By adopting the above technical solution, the first protective net is driven by the sliding frame to cover the outside of the mold, so that the impurities peeled off from the inside of the mold after cleaning can be effectively isolated inside to prevent the impurities from moving into the ultrasonic cleaning liquid. Then, after the mold is lifted from the inside of the lifting water tank, it is convenient to clean the peeled impurities so that the inside of the ultrasonic cleaning liquid remains clean. By continuously opening and closing the support frame during the lifting and lowering of the lifting water tank, the filter cotton will only filter the dirt and dust inside the ultrasonic cleaning liquid at the bottom of the inner cavity of the lifting water tank. Thereby further improving the cleanliness of the internal ultrasonic cleaning liquid when the lifting water tank is raised, so that the cleaning liquid can be used multiple times and the utilization rate is improved. By using the elastic force of the spring to drive the telescopic rod to support the positioning support plate, the mold is clamped and fixed on the top of the placement frame. Thereby, the mold can be fixed in the center position to prevent the mold from being offset and ensure the ultrasonic cleaning effect on the mold.

[0008] The present invention is further configured as follows: the positioning mechanism comprises a sliding cover plate that is slidably connected to the surface of the support column, the surface of the bidirectional screw is threadedly sleeved with a first threaded sleeve that is fixedly connected to the sliding cover plate, and the support column is fixedly installed with a fixed rack on a side of the support column close to the sliding cover plate, the sliding cover plate is internally rotatably connected to the first gear that meshes with the fixed rack, the sliding cover plate is internally rotatably connected to a rotating rod, and a transmission belt is fixedly sleeved between the rotating rod and the first gear. A placing rack is provided at the bottom of the sliding cover plate, and a connecting rod is fixedly connected between the sliding cover plate and the placing rack, and a sliding frame that is slidably connected to the connecting rod is provided between the sliding cover plate and the placing rack, and two threaded rods that are threadedly connected to the sliding frame between the placing rack and the sliding cover plate are symmetrically rotatably connected, the tops of the two threaded rods are fixedly sleeved with the first bevel gear that is rotatably connected to the sliding cover plate, and the two ends of the rotating rod are fixedly sleeved with the second bevel gear that meshes with the first bevel gear, and the thread directions of the two threaded rods are opposite.

[0009] By adopting the above technical solution, when the two second bevel gears drive the first bevel gear to rotate, the two threaded rods with opposite thread directions can rotate in opposite directions. After the threaded rods engage with the sliding frame threads, they can transmit the same lifting force, thereby not interfering with the up and down movement of the sliding frame.

[0010] The present invention is further configured as follows: a second protective net is fixedly installed inside the placement rack, a first protective net fixedly connected to the top of the sliding frame is fixedly connected to the sliding cover plate, a telescopic rod is fixedly installed inside the sliding frame, one end of the telescopic rod away from the sliding frame is fixedly connected to a positioning support plate, and the surface of the telescopic rod is provided with springs fixedly connected to the sliding frame and the positioning support plate respectively.

[0011] By adopting the above technical solution, impurities peeled off from the inside of the mold after cleaning can be isolated inside to prevent the impurities from moving into the ultrasonic cleaning liquid. At the same time, the mold can be fixed in the center position to prevent the mold from shifting in position.

[0012] The present invention is further configured as follows: the filtering mechanism includes a second threaded sleeve threadedly sleeved on one end of the surface of the bidirectional screw near the inside of the cleaning box, the second threaded sleeve is fixedly connected to the lifting water tank, the bottom of the inner cavity of the cleaning box is fixedly connected to a fixed sleeve slidingly connected to the lifting water tank, the top of the fixed sleeve is fixedly installed with a support frame slidingly connected to the inner wall of the lifting water tank, both sides of the support frame are rotatably connected to a rotating frame, the inside of the rotating frame is fixedly installed with filter cotton, both sides of the inside of the lifting water tank are slidably connected with sliding racks, one end of the rotating frame near the inner wall of the lifting water tank is fixedly sleeved with a second gear meshing with the sliding rack, and the side of the sliding rack away from the second gear is fixedly sleeved with a rubber anti-slip sleeve slidably connected to the lifting water tank.

[0013] By adopting the above technical scheme, the dirt and dust inside the ultrasonic cleaning liquid are filtered at the bottom of the inner cavity of the lifting water tank, further improving the cleanliness of the internal ultrasonic cleaning liquid when the lifting water tank is raised, so that the cleaning liquid can be used multiple times.

[0014] The present invention is further configured as follows: an ultrasonic generator is installed at the bottom of the cleaning box, a vibrator is fixedly installed at the top of the support frame, and a connecting line that runs through the inside of the fixed sleeve is fixedly connected between the ultrasonic generator and the vibrator.

[0015] By adopting the above technical solution, the ultrasonic generator is turned on and the vibrator is driven to work using the connecting line, so that the vibrator can generate ultrasonic waves, so that the microbubbles in the cleaning liquid can generate high-frequency vibrations under ultrasonic waves to clean the mold.

[0016] The present invention is further configured as follows: the surface and the interior of the fixed sleeve are fixedly sleeved with sealing rings respectively used in conjunction with the lifting water tank and the connecting line.

[0017] The above technical solution is adopted to improve the sealing performance, thereby preventing the cleaning liquid from leaking out of the front drive.

[0018] The present invention is further configured as follows: a drain valve is fixedly connected to one side of the bottom of the lifting water tank, and a slide groove slidably connected to the drain valve is opened on one side of the outside of the cleaning tank.

[0019] The above technical solution is adopted to facilitate the discharge of turbid cleaning liquid at the bottom of the lifting water tank, and at the same time, the drain valve can slide freely up and down using the slide groove.

[0020] The present invention is further configured as follows: a sealing strip used in conjunction with the sliding cover plate is bonded to the top of the cleaning box.

[0021] By adopting the above technical solution, the sealing between the cleaning box and the sliding cover plate is improved, and impurities are prevented from entering the interior during mold cleaning.

[0022] The present invention is further configured as follows: an anti-slip sticker is fixedly connected to the top of the placement rack.

[0023] By adopting the above technical solution, the friction force on the top of the placement rack is increased, thereby further improving the stability of mold placement.

[0024] In summary, the present invention has the following beneficial effects:

[0025] 1. The sliding frame drives the first protective net to cover the outside of the mold, so that the impurities peeled off from the inside of the mold after cleaning can be effectively isolated inside to prevent the impurities from moving into the ultrasonic cleaning liquid. After the mold is lifted from the inside of the lifting water tank, it is convenient to clean the peeled impurities and keep the inside of the ultrasonic cleaning liquid clean;

[0026] 2. By continuously opening and closing the support frame during the lifting and lowering of the lifting water tank, the filter cotton will only filter the dirt and dust inside the ultrasonic cleaning liquid at the bottom of the lifting water tank. This will further improve the cleanliness of the internal ultrasonic cleaning liquid when the lifting water tank is raised, so that the cleaning liquid can be used multiple times and the utilization rate is improved;

The first protective net 613 is driven by the sliding frame 612 to cover the outside of the mold, so that the impurities peeled off from the inside of the mold after cleaning can be effectively isolated inside to prevent the impurities from moving into the ultrasonic cleaning liquid. Then, after the mold is lifted from the inside of the lifting water tank 2, it is convenient to clean the peeled impurities, so that the inside of the ultrasonic cleaning liquid is kept clean. By continuously opening and closing the support frame 703 during the process of lifting the lifting water tank 2 up and down, the filter cotton 705 will only filter the dirt and dust inside the ultrasonic cleaning liquid at the bottom of the inner cavity of the lifting water tank 2.

When the two second bevel gears 611 drive the first bevel gear 610 to rotate, the two threaded rods 609 rotate in opposite directions. After the threaded rods 609 and the sliding frame 612 are threadedly engaged, the same lifting force can be transmitted, so as not to interfere with the up and down movement of the sliding frame 612.

The dirt and dust inside the ultrasonic cleaning liquid are filtered at the bottom of the inner cavity of the lifting water tank 2, which further improves the cleanliness of the internal ultrasonic cleaning liquid when the lifting water tank 2 is raised, so that the cleaning liquid can be used multiple times.

[0042] refer to Figure 3 , Figure 4 An ultrasonic generator 8 is installed at the bottom of the cleaning box 1, a vibrator 9 is fixedly installed on the top of the support frame 703, and a connecting line 10 that runs through the interior of the fixed sleeve 702 is fixedly connected between the ultrasonic generator 8 and the vibrator 9. By turning on the ultrasonic generator 8 and using the connecting line 10 to drive the vibrator 9 to work, the vibrator 9 can generate ultrasonic waves, so that the microbubbles in the cleaning liquid can generate high-frequency vibrations under ultrasonic waves to clean the mold.

[0043] refer to Figure 3 , Figure 4 , Figure 5 The surface and the interior of the fixed sleeve 702 are fixedly sleeved with sealing rings 11 respectively used in conjunction with the lifting water tank 2 and the connecting line 10. The sealing performance is improved, thereby preventing the cleaning liquid from leaking out of the front drive.

[0044] refer to Figure 1 , Figure 3 , Figure 4 A drain valve 12 is fixedly connected to one side of the bottom of the lifting water tank 2, and a chute 13 is opened on one side of the outside of the cleaning tank 1 to be slidably connected to the drain valve 12. It is convenient to discharge the turbid cleaning liquid at the bottom of the lifting water tank 2, and at the same time, the drain valve 12 can slide freely up and down using the chute 13.

[0045] refer to Figure 1 , Figure 3 , Figure 4 The top of the cleaning box 1 is bonded with a sealing strip 14 used in conjunction with the sliding cover plate 601. The sealing between the cleaning box 1 and the sliding cover plate 601 is improved to prevent impurities from entering the interior during mold cleaning.

[0046] refer to Figure 1 , Figure 2 The top of the placement rack 608 is fixedly connected with an anti-skid sticker 15. The friction force on the top of the placement rack 608 is increased, thereby further improving the stability of the mold placement.

[0047] Brief description of the use process: First, place the mold on the top of the placement rack 608, then turn on the servo motor 5 to drive the bidirectional screw 4 to rotate, so that the bidirectional screw 4 is threadedly engaged with the first threaded sleeve 602 and the second threaded sleeve 701 respectively, driving the sliding cover plate 601 to move downward and the lifting water tank 2 to move upward, so that the two are close to each other, so that the top of the placement rack 608 and the mold can be lowered into the cleaning tank 1 and then immersed in the ultrasonic cleaning liquid inside the lifting water tank 2. At the same time, the sliding cover plate 601 drives the first gear 604 to mesh with the fixed rack 603 during the downward movement, so that the first gear 604 can synchronously drive the rotating rod 605 to rotate using the transmission belt 606, thereby rotating the second bevel gear 611 and meshing with the first bevel gear 610, so that the threaded rod 609 rotates between the placement rack 608 and the sliding cover plate 601. Then, the threaded rod 609 and the sliding frame 612 are threadedly engaged with each other, so that the sliding frame 612 slides downward again through the positioning of the connecting rod 607, and the first protective net 613 is pulled to cover the mold surface. The first protective net 613 and the second protective net 614 cooperate with each other to prevent the cleaned impurities from escaping. At the same time, after the sliding frame 612 moves to the mold surface, the elastic force of the spring 616 drives the telescopic rod 615 to support the positioning support plate 617, and the mold is clamped and fixed on the top of the placement frame 608, so that the mold is fixed in the center position to prevent position deviation.

[0048] Afterwards, the lifting water tank 2 is driven upward by the second threaded sleeve 701 through the bidirectional screw 4, and the sliding rack 706 is meshed with the second gear 707, thereby driving the rotating frame 704 to rotate inside the support frame 703, so that the rotating frame 704 covers the opening at the top of the support frame 703, so that the ultrasonic cleaning liquid inside the lifting water tank 2 is filtered by the filter cotton 705 after the lifting water tank 2 is lifted, and the dirt and dust are filtered at the bottom. At the same time, after the sliding rack 706 and the second gear 707 are meshed at the maximum position, the sliding rack 706 overcomes the friction between the rubber anti-skid cover 708 and the lifting water tank 2, thereby driving the rubber anti-skid cover 708 to slide downward to the bottom. Therefore, when the bidirectional screw rod 4 drives the lifting water tank 2 to move downward, the sliding rack 706 can mesh with the second gear 707 to drive the rotating frame 704 to rotate in the opposite direction, and after rotating to the limit, it continues to overcome the friction between the rubber anti-slip sleeve 708 and the lifting water tank 2, and slides the rubber anti-slip sleeve 708 upward to the top, thereby opening the support frame 703, so that the filter cotton 705 does not filter the turbid ultrasonic cleaning liquid. The filter cotton 705 only filters the dirt and dust inside the ultrasonic cleaning liquid at the bottom of the inner cavity of the lifting water tank 2, thereby reducing the dust inside the ultrasonic cleaning liquid and improving the cleaning effect on the mold.

[0049] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
