Description

Technical Field

[0001] This utility model belongs to the field of mold water filtration technology, specifically a coolant circulation filtration device for cold pressing mold processing. Background Technology

[0002] During the cold pressing process, frictional heat is generated between the mold and the workpiece. At the same time, heat is also generated inside the mold due to the large pressure. The coolant circulates in the cooling channel of the mold to remove this heat, prevent the mold temperature from getting too high, avoid thermal deformation that could affect the accuracy and life of the mold, and ensure that the mold can maintain stable dimensions and shape, thereby ensuring that the pressed workpiece meets the quality requirements.

[0003] Water in a water cooling system may carry various impurities, such as rust, sand, and metal shavings. A filter device can intercept these impurities through a filter screen to prevent them from entering the mold's water circuit and avoid clogging of the cooling water circuit in the cold-pressing mold due to the accumulation of impurities. However, the filter screen in the filter device will become clogged with impurities after long-term use, so it is necessary to clean the inside of the filter device and the filter screen regularly. However, the cold-pressing mold cannot be used when cleaning the filter device, which affects production efficiency. Therefore, we propose a coolant circulation filter device for cold-pressing mold processing. Utility Model Content

[0004] The purpose of this invention is to provide a coolant circulation and filtration device for cold pressing mold processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling fluid circulation and filtration device for cold pressing mold processing, comprising a cold pressing mold, wherein the inlet of the cooling water circuit of the cold pressing mold is connected to a first three-way valve, both sets of inlets of the first three-way valve are connected to a set of filter pipes, the inlets of the two sets of filter pipes are connected to a second three-way valve, a notch is provided at the top of the filter pipe, an arc-shaped pressure plate is placed in the notch, a first filter plate and a second filter plate are provided at the bottom of the arc-shaped pressure plate, a viewing window is embedded in the top of the arc-shaped pressure plate, the viewing window is located on the top of the first filter plate and the second filter plate, threaded holes are uniformly provided at the bottom of the inner sidewall of the notch, and countersunk holes are uniformly provided through the top of the arc-shaped pressure plate, anti-loosening cross bolts are provided in the countersunk holes, and the anti-loosening cross bolts are screwed into the threaded holes.

[0006] Preferably, the outer wall of the arc-shaped pressure plate has a first sealing gasket, and the outer wall of the first sealing gasket is in contact with the inner wall of the notch.

[0007] Preferably, a set of second sealing gaskets are evenly placed at the bottom of the first filter plate and the second filter plate, and the bottom of the second sealing gaskets is in contact with the inner wall of the filter tube.

[0008] Preferably, the first filter plate is located in front of the second filter plate, and the diameter of the filter holes in the second filter plate is smaller than the diameter of the filter holes in the first filter plate.

[0009] Preferably, a second conical plug is uniformly provided on the top of the second sealing gasket, and a second snap-fit ​​hole is uniformly provided on the bottom of the first filter plate and the second filter plate, and the second conical plug is snapped into the second snap-fit ​​hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by having two sets of filter tubes work together, when one set of filter tubes is cleaning impurities, the other set of filter tubes can perform filtration for the cold pressing mold, so that the cold pressing mold can continuously process the workpiece. Furthermore, by having two sets of filter plates with different pore sizes inside the filter tubes, the circulating coolant can be filtered twice, thereby improving the filtration effect.

[0012] The two sets of sealing gaskets ensure a good seal and prevent water leakage between the filter tube and the arc-shaped pressure plate. Since the second sealing gasket is fixed to the first and second filter plates by the second cone plug, it can be directly removed and replaced. Similarly, the first sealing gasket is fixed to the arc-shaped pressure plate by the first cone plug, so it can be directly removed and replaced. This ensures the device is sealed and leak-proof, thereby improving the reliability of the device. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-3 A cooling fluid circulation and filtration device for cold pressing mold processing includes a cold pressing mold 1. The inlet of the cooling water circuit of the cold pressing mold 1 is connected to a first three-way valve 11. Each of the two inlets of the first three-way valve 11 is connected to a filter pipe 12. The inlets of the two filter pipes 12 are connected to a second three-way valve 13. The second three-way valve 13 is connected to an external circulating water circuit. At this time, the cooling circulating water can enter the cooling water circuit of the cold pressing mold 1 through the second three-way valve 13, the filter pipes 12, and the first three-way valve 11 to cool the cold pressing mold 1. A notch is provided at the top of the filter pipe 12, and an arc-shaped pressure plate 14 is placed inside the notch. A first filter plate 18 and a second filter plate 19 are fixedly installed at the bottom of the arc-shaped pressure plate 14. A visible... The observation window 17 is fixedly installed on the top of the first filter plate 18 and the second filter plate 19. The filtration of cooling circulating water by the first filter plate 18 and the second filter plate 19 can be observed through the observation window 17. Threaded holes are evenly opened at the bottom of the inner side wall of the notch. Countersunk holes are evenly opened through the top of the arc-shaped pressure plate 14. Anti-loosening cross bolts 16 are rotatably installed in the countersunk holes and are screwed into the threaded holes. The first filter plate 18 is located in front of the second filter plate 19. The diameter of the filter holes of the second filter plate 19 is smaller than that of the filter holes of the first filter plate 18. When the cooling circulating water flows through the filter pipe 12, it is initially filtered by the first filter plate 18 and then secondarily filtered by the second filter plate 19, thereby improving the filtration effect.

[0021] The outer wall of the arc-shaped pressure plate 14 has a first sealing gasket 15. The outer wall of the first sealing gasket 15 fits against the inner wall of the notch. The outer wall of the first sealing gasket 15 is uniformly fixed with a first conical plug 151. The first conical plug 151 and the first sealing gasket 15 are integrally processed. The outer wall of the arc-shaped pressure plate 14 is uniformly provided with first snap-fit ​​holes. The first conical plug 151 is snapped into the first snap-fit ​​holes. The first sealing gasket 15 is snapped and fixed to the outer side of the arc-shaped pressure plate 14 by the first conical plug 151. When the arc-shaped pressure plate 14 is fixed in the notch of the filter tube 12 by the anti-loosening cross bolt 16, the connection gap between the arc-shaped pressure plate 14 and the filter tube 12 can be sealed by the first sealing gasket 15.

[0022] A set of second sealing gaskets 2 are evenly placed at the bottom of the first filter plate 18 and the second filter plate 19. The bottom of the second sealing gasket 2 is in contact with the inner wall of the filter tube 12. A second conical plug 21 is evenly fixed at the top of the second sealing gasket 2. The second conical plug 21 and the second sealing gasket 2 are integrally processed. The bottom of the first filter plate 18 and the second filter plate 19 are evenly provided with second snap-fit ​​holes. The second conical plug 21 is snapped into the second snap-fit ​​holes. The second sealing gasket 2 is snapped and fixed at the bottom of the first filter plate 18 and the second filter plate 19 by the second conical plug 21, so that the second sealing gasket 2 seals the connection gap between the first filter plate 18 and the second filter plate 19 and the filter tube 12.

[0023] Working principle: The first sealing gasket 15 is snapped and fixed to the outside of the arc-shaped pressure plate 14 by the first conical plug 151. When the arc-shaped pressure plate 14 is fixed in the notch of the filter tube 12 by the anti-loosening cross bolt 16, the first sealing gasket 15 can seal the connection gap between the arc-shaped pressure plate 14 and the filter tube 12. The second sealing gasket 2 is snapped and fixed to the bottom of the first filter plate 18 and the second filter plate 19 by the second conical plug 21, so that the second sealing gasket 2 connects the first filter plate 18 and the second filter plate 19 to the filter tube 12. The gap is sealed, and the second three-way valve 13 is connected to the external circulating water circuit. At this time, the cooling circulating water can enter the cooling water circuit of the cold pressing mold 1 through the second three-way valve 13, the filter pipe 12 and the first three-way valve 11 to cool the cold pressing mold 1. When the cooling circulating water flows through the filter pipe 12, it is initially filtered by the first filter plate 18 and then filtered a second time by the second filter plate 19 to improve the filtration effect. The filtration of the cooling circulating water by the first filter plate 18 and the second filter plate 19 can be observed through the viewing window 17.

[0024] When it is necessary to clean the impurities in a certain group of filter tubes 12, taking the filter tube 12 connected to the left side of the first three-way valve 11 and the second three-way valve 13 as an example: by turning the handwheels on the second three-way valve 13 and the first three-way valve 11, the second three-way valve 13 and the first three-way valve 11 are connected to the filter tube 12 installed on their right side. At this time, the cooling circulating water will enter the cold pressing mold 1 through the filter tube 12 on the right side. Then, after unscrewing the anti-loosening cross bolt 16 on the filter tube 12 on the left side, the arc-shaped pressure plate 14 can be moved upward and removed. At this time, the arc-shaped pressure plate 14 will connect the first sealing gasket 15, the first filter plate 18, and the second filter plate. 19 and the second sealing gasket 2 are removed together, so that the impurities accumulated in the left filter tube 12, as well as the impurities on the first filter plate 18 and the second filter plate 19 originally located in the left filter tube 12, can be cleaned. Since the second sealing gasket 2 is fixed to the first filter plate 18 and the second filter plate 19 by the second cone plug 21, the second sealing gasket 2 can be directly removed and replaced. Similarly, the first sealing gasket 15 is fixed to the arc-shaped pressure plate 14 by the first cone plug 151, so the first sealing gasket 15 can be directly removed and replaced, thereby ensuring the sealing and leak-proof performance of the device and improving the reliability of the device.
