Description

Technical Field

[0001] This utility model relates to the field of low-temperature wax mold filtration technology, specifically a low-temperature wax mold filtration device. Background Technology

[0002] The low-temperature wax pattern filtration device is a specialized piece of equipment used in precision casting. It primarily filters impurities from low-temperature wax materials, ensuring the purity of the wax pattern and the quality of the finished product. Its core structure includes a heating system, a filter screen (typically made of stainless steel or ceramic), and pressure control components. The wax material is kept fluid through constant temperature heating, and then multiple layers of filtration remove particulate matter. This device effectively reduces casting defects and improves surface finish. It is widely used in high-end precision casting fields such as aerospace and automotive, and features easy operation, high filtration efficiency, and low maintenance costs.

[0003] A search revealed a Chinese patent that discloses a casting wax filtration device and method (authorization announcement number CN116510386B), which also belongs to the field of filtration technology. The patent includes "a filter box and an extension box, the extension box being installed on one side of the filter box and communicating with the interior of the filter box, and a first screen plate being horizontally fixed inside the filter box. The first screen plate and the bottom of the extension box are at the same height, and a U-shaped frame slides on the top of the first screen plate, with a second screen plate horizontally arranged between the two short sides of the U-shaped frame." This patented technology can automatically clean the filtered impurities, preventing the first screen plate from becoming clogged and failing to filter the wax. It also eliminates the need for manual disassembly and cleaning, thus improving the ease of use of the equipment.

[0004] However, in this patented technology, when the cleaning roller cleans the first screen plate, the cleaning roller is always in contact with the surface of the first screen plate. This causes the cleaning roller to push the impurities to both sides when it moves back and forth, making it difficult to collect and process the impurities. In order to address the above problems, the inventor proposes a low-temperature wax mold filtration device to solve the above problems. Utility Model Content

[0005] In order to solve the problem of efficient cleaning of wax mold filter screens, the purpose of this utility model is to provide a low-temperature wax mold filter device.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a low-temperature wax mold filtering device, comprising a filter box, wherein a filter plate is provided inside the filter box, a pressure strip is slidably engaged on one side inside the filter box, an L-shaped rod is rotatably connected to the top of the pressure strip, a cleaning plate is fixedly connected to the front end of the L-shaped rod, the bottom end of the cleaning plate is in contact with the top surface of the filter plate, an electric telescopic rod is fixedly installed on the side of the filter box near the L-shaped rod, the piston rod of the electric telescopic rod extends into the interior of the filter box and is fixedly connected to a U-shaped frame, both ends of the U-shaped frame are provided with movable grooves, both ends of the top of the L-shaped rod are fixedly connected to movable columns, the movable columns are movably engaged in the corresponding movable grooves, two symmetrically distributed wax pools are fixedly connected on both sides of the bottom of the filter box and in the same direction as the mounting frame, and an oil outlet pipe communicating with the interior of the filter box is fixedly connected to one side of the bottom of the filter box.

[0007] Preferably, the side of the filter box is slidably attached to an installation frame, and the top of the installation frame has two symmetrically distributed installation slots, in which the filter plate is placed.

[0008] Preferably, the filter box has limiting grooves on both sides, and the mounting frame has limiting frames fixedly connected to both ends, with the limiting frames snapping into the limiting grooves.

[0009] Preferably, a collection frame is fixedly connected to the side of the filter box away from the electric telescopic rod, a valve plate is slidably engaged with the bottom inner side of the collection frame, and a scraper is fixedly connected to one side of the inner wall of the collection frame, with the bottom end of the scraper contacting the top surface of the valve plate.

[0010] Preferably, a pull rod is fixedly connected to both the side of the limiting frame that is far apart from each other and the side of the valve plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By extending the piston rod of the electric telescopic rod, the U-shaped frame is pushed to one side of the filter plate. First, the L-shaped rod and the cleaning plate are pushed downward to rotate, and the rotation of the cleaning plate is limited by the pressure strip. When the bottom end of the cleaning plate contacts the top surface of the filter plate, the U-shaped frame is pushed further, and the pressure strip and scraper move to one side of the filter plate. The cleaning plate cleans the top surface of the filter plate. When the piston rod of the electric telescopic rod retracts, it first drives the L-shaped rod and the cleaning plate to rotate upward, so that the bottom end of the cleaning plate no longer contacts the top surface of the filter plate. This prevents the cleaning plate from bringing impurities from the back side of the cleaning plate back into the filter box during the return process, further improving the cleaning efficiency.

[0013] 2. When the filter plate needs to be replaced, place the replacement filter plate into the mounting slot on the outside, then push the outer filter plate into the filter box, and push the filter plate to be replaced out of the filter box. This ensures that the filter plate can be easily replaced while the equipment is running continuously, further improving the filtration efficiency of the wax mold. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1-6 As shown, this utility model provides a low-temperature wax mold filtering device, including a filter box 1, a filter plate 2 inside the filter box 1, a pressure strip 3 slidably engaged on one side inside the filter box 1, an L-shaped rod 4 rotatably connected to the top of the pressure strip 3, a cleaning plate 5 fixedly connected to the front end of the L-shaped rod 4, the bottom end of the cleaning plate 5 contacting the top surface of the filter plate 2, an electric telescopic rod 6 fixedly installed on the side of the filter box 1 near the L-shaped rod 4, the piston rod of the electric telescopic rod 6 extending into the interior of the filter box 1 and fixedly connected to a U-shaped frame 7, both ends of the U-shaped frame 7 having movable grooves 18, and both ends of the top of the L-shaped rod 4 being fixedly connected to movable columns 19, which are movably engaged in the corresponding movable grooves 18.

[0024] The side of the filter box 1 is slidably connected to the mounting frame 8. The top of the mounting frame 8 has two symmetrically distributed mounting slots 9, and the filter plate 2 is placed in the mounting slots 9.

[0025] By adopting the above technical solution, when the filter plate 2 needs to be replaced, the replacement filter plate 2 is placed inside the mounting groove 9 on the outside. Then, the filter plate 2 on the outside is pushed into the filter box 1, and the filter plate 2 to be replaced inside the filter box 1 is pushed out from the inside of the filter box 1. This ensures that the filter plate 2 can be easily replaced while the equipment is running continuously, and further improves the filtration efficiency of the wax mold.

[0026] Limiting grooves 11 are provided on both sides of the filter box 1, and limiting frames 10 are fixedly connected to both ends of the mounting frame 8. The limiting frames 10 are snapped into the limiting grooves 11.

[0027] By adopting the above technical solution, the cooperation between the limiting frame 10 and the limiting groove 11 facilitates the lateral movement of the mounting frame 8.

[0028] Two symmetrically distributed wax-reducing pools 12 are fixedly connected to both sides of the bottom of the filter box 1 and in the same direction as the mounting frame 8.

[0029] By adopting the above technical solution, when the filter plate 2 located inside the filter box 1 is pushed out from the inside of the filter box 1, there will be wax residue at the top of the filter box 1. By setting the wax draining pool 12, it is convenient to collect the dripping wax.

[0030] A collection frame 13 is fixedly connected to the side of the filter box 1 away from the electric telescopic rod 6. A valve plate 14 is slidably engaged on the inner bottom of the collection frame 13. A scraper 15 is fixedly connected to one side of the inner wall of the collection frame 13. The bottom end of the scraper 15 is in contact with the top surface of the valve plate 14.

[0031] By adopting the above technical solution, the collection frame 13 can be set to collect the cleaned impurities. At the same time, by pulling the valve plate 14 away from the filter box 1, it is easy to discharge the impurities inside the collection frame 13. Furthermore, during the process of pulling the valve plate 14, the scraper 15 is used to scrape the impurities stuck to the top surface of the valve plate 14, thereby further improving the cleaning effect.

[0032] Pull rods 16 are fixedly connected to the side of the limiting frame 10 that is far apart from each other and the side of the valve plate 14.

[0033] By adopting the above technical solution and setting the pull rod 16, it is easier to pull the limit frame 10 and the valve plate 14.

[0034] An oil outlet pipe 17, which communicates with the interior of the filter box 1, is fixedly connected to one side of the bottom end of the filter box 1.

[0035] By adopting the above technical solution and setting up the oil outlet pipe 17, it is convenient to discharge the filtered wax liquid.

[0036] Working principle: When filtering low-temperature wax molds, the molten wax is introduced into the filter box 1 from the top. As it passes through the surface of the filter plate 2, impurities in the molten wax are filtered out. After a period of use, impurities accumulate on the top surface of the filter plate 2, causing the mesh of the filter plate 2 to become clogged. At this time, the extension of the piston rod of the electric telescopic rod 6 pushes the U-shaped frame 7 to one side of the filter plate 2. When the U-shaped frame 7 moves, it first pushes the L-shaped rod 4 and the cleaning plate 5 to rotate downwards. The pressure strip 3 limits the rotation of the cleaning plate 5, so that the bottom end of the cleaning plate 5 is in contact with the filter plate 2. The top surfaces of the filter plates 2 come into contact with each other. Then, as the piston rod of the electric telescopic rod 6 extends, it pushes the cleaning plate 5 and the pressure strip 3 to one side of the filter plate 2. The cleaning plate 5 cleans the top surface of the filter plate 2 and pushes the impurities on the top of the filter plate 2 to one side of the collection frame 13. The collection frame 13 collects the impurities. When the piston rod of the electric telescopic rod 6 retracts, it first drives the L-shaped rod 4 and the cleaning plate 5 to rotate upward so that the bottom end of the cleaning plate 5 no longer contacts the top surface of the filter plate 2. Then, the pressure strip 3 is reset to prevent the cleaning plate 5 from bringing the impurities on the back side of the cleaning plate 5 back into the filter box 1 during the return process.

[0037] Furthermore, by pulling the valve plate 14 away from the filter box 1, it is easy to discharge the impurities inside the collection frame 13. In the process of pulling the valve plate 14, the scraper 15 is used to scrape the impurities stuck to the top surface of the valve plate 14, which further improves the cleaning effect.

[0038] When the filter plate 2 needs to be replaced, the replacement filter plate 2 is placed inside the mounting slot 9 on the outside. Then, the filter plate 2 on the outside is pushed into the filter box 1, and the filter plate 2 to be replaced inside the filter box 1 is pushed out from the inside of the filter box 1. This ensures that the filter plate 2 can be easily replaced while the equipment is running continuously, and further improves the filtration efficiency of the wax mold.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
