Description

Technical Field

[0001] This invention relates to the field of cooling and filtration technology, specifically to a filtration structure based on automatic slag removal and a cooling and filtration system for injection molds. Background Technology

[0002] The cooling system of the mold is as follows: the coolant is centrally delivered to the mold supply water collection module through temperature control and pumping equipment, and then pumped to the water inlet of each cooling pipe inside the mold. After flowing out from the water outlet, it returns to the mold water outlet collection module, and then back to the temperature control and pumping equipment, thus forming a complete cooling loop.

[0003] Before pumping the coolant, it needs to be filtered to prevent blockage of the cooling circuit due to the accumulation of impurities when it is pumped into the mold cooling circuit.

[0004] Existing coolant filtration systems typically deliver cooling water from a tank to a filtration device, where it is filtered. As the amount of cooling water filtered increases, impurities accumulate within the filtration device, potentially causing blockage of the filter pores. Since existing filtration systems cannot automatically remove these impurities, the system needs to be shut down for cleaning, which in turn affects the cooling of the injection mold. Summary of the Invention

[0005] The purpose of this invention is to provide a filtration structure based on automatic slag removal and a cooling filtration system for injection molds, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The filter structure based on automatic sludge removal includes:

[0008] The first processing tank and the second processing tank are arranged symmetrically to each other. The first processing tank and the second processing tank are connected to each other through a bidirectional conveying pipe and a bidirectional discharge pipe. The bidirectional conveying pipe is connected to an inlet pipe, and the bidirectional discharge pipe is connected to a guide pipe.

[0009] Also includes:

[0010] A filter bucket is fixedly installed inside the first processing tank and the second processing tank, respectively. The outer circumferential wall of the filter bucket is provided with a plurality of filter holes that are equidistantly distributed in a circle.

[0011] A reciprocating drive mechanism is provided inside the filter barrel. An upper filter disc and a lower filter disc are connected to the reciprocating drive mechanism. The reciprocating drive mechanism can drive the upper filter disc and the lower filter disc to reciprocate along the length direction of the filter barrel.

[0012] A conduction control mechanism is disposed on the upper filter disc and connected to the lower filter disc. The conduction control mechanism can adjust the distance between the upper filter disc and the lower filter disc to adjust the conduction state between the upper filter disc and the lower filter disc.

[0013] An impurity release component is disposed inside the filter barrel and connected to the reciprocating drive mechanism. The reciprocating drive mechanism can drive the impurity release component to move when the lower filter plate cooperates with the impurity release component.

[0014] As a further embodiment of the present invention: the reciprocating driving mechanism includes a rotating rod rotatably installed inside the filter barrel, the outer circumferential wall of the rotating rod is provided with a spiral groove, symmetrically arranged guide columns are fixed inside the filter barrel, the upper filter plate and the lower filter plate are slidably connected to the rotating rod and the guide columns respectively, and a guide component connected to the guide column is provided on the rotating rod.

[0015] As a further embodiment of the present invention: the guide assembly includes a movable sleeve slidably mounted on the rotating rod, a limiting block fixed to the inner wall of the movable sleeve and slidably connected to the spiral groove, a connecting plate fixed to the movable sleeve and slidably connected to the guide post, and a driven structure connected to the lower filter disc on the movable sleeve.

[0016] As a further embodiment of the present invention: the driven structure includes a limiting groove formed on the lower filter disc, a limiting ring fixed at the end of the movable sleeve and slidably connected to the limiting groove, and a first spring sleeved on the movable sleeve, the two ends of the first spring respectively abutting against the connecting plate and the upper filter disc.

[0017] As a further embodiment of the present invention: the conduction control mechanism includes a support rod fixedly installed on the lower filter plate and passing through the upper filter plate, a support sleeve fixedly sleeved on the upper filter plate and an elastic component connected to the support rod on the support sleeve.

[0018] As a further embodiment of the present invention: the elastic component includes a groove formed on the outer wall of the support sleeve, a fixing ring fixed on the support rod and slidably connected to the groove, a second spring sleeved on the support sleeve and abutting against the fixing ring, and a misalignment structure provided on the lower filter disc and the upper filter disc.

[0019] As a further embodiment of the present invention: the misaligned structure includes a plurality of first discharge holes that are equidistantly distributed on the upper filter plate and the lower filter plate has a plurality of second discharge holes that are equidistantly distributed on the lower filter plate, and a scraper that cooperates with the filter barrel is fixed on the lower filter plate.

[0020] As a further embodiment of the present invention: the impurity release assembly includes a support ring fixedly installed inside the filter barrel, a conical disk that abuts against the support ring is slidably installed on the rotating rod, and a third spring that abuts against the conical disk is sleeved on the rotating rod.

[0021] As a further embodiment of the present invention: the filter can be divided into multiple chambers, namely an upper chamber, a middle chamber, and a lower chamber.

[0022] The cooling and filtration system for injection molds includes the following steps:

[0023] Step 1: The cooling water in the water tank is transported to the first treatment tank and the second treatment tank through the inlet pipe and the bidirectional conveying pipe, respectively;

[0024] Step 2: The cooling water will be filtered through the filter holes, and the upper and lower filter plates will move under the action of the reciprocating push mechanism to clean the impurities in the filter barrel;

[0025] Step 3: When the lower filter disc moves to the position where it engages with the impurity release component, the upper and lower filter discs are brought into contact with each other by the control mechanism. At the same time, the impurity release component is moved by the reciprocating push mechanism, so that the impurities placed below the lower filter disc are discharged to the bottom of the filter barrel.

[0026] Step 4: The filtered cooling water is transported to the cold mold temperature controller through a two-way discharge pipe and a guide pipe for temperature control and cooling. After cooling, it is transported to the injection mold for cooling treatment.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: This application can clean the impurities filtered out of the cooling water by adjusting the position of the filter disc. When the reciprocating push mechanism moves, it drives the upper and lower filter discs to move. Under the action of the conduction control mechanism, the impurities remaining on the inner wall of the filter barrel are scraped off to ensure that the filter holes are not blocked. When the lower filter disc moves to the position that matches the impurity release component, under the action of the conduction control mechanism, the upper filter disc and the lower filter disc are made to fit together, so that the two filter discs are in a blocked state. At the same time, under the action of the reciprocating push mechanism, the impurity release component is driven to move to transport the impurities below the lower filter disc to the bottom of the processing tank, thereby achieving the effect of automatic cleaning of impurities.

[0028] The operation of one or both treatment tanks can be freely controlled by the bidirectional delivery and discharge pipes, thereby achieving the effect of adjusting the cooling water treatment rate according to cooling requirements.

[0029] The control mechanism allows cooling water to flow freely before the lower filter disc engages with the impurity release component, ensuring the filtration rate of the cooling water. When the lower filter disc engages with the impurity release component, the lower filter disc will fit against the upper filter disc, keeping both filter discs in a blocked state to ensure that cooling water does not enter the bottom of the treatment tank during the impurity cleaning process.

[0044] Please see Figures 1 to 11 In this embodiment of the invention, the filter structure based on automatic slag removal includes:

[0045] The first processing tank 1 and the second processing tank 2 are arranged symmetrically to each other. The first processing tank 1 and the second processing tank 2 are connected to each other through a bidirectional conveying pipe 3 and a bidirectional discharge pipe 5. The bidirectional conveying pipe 3 is connected to an inlet pipe 4, and the bidirectional discharge pipe 5 is connected to a guide pipe 6.

[0046] The feed pipe 4 is connected to a water tank containing cooling water. Valves are installed on the bidirectional conveying pipe 3 and the bidirectional discharge pipe 5, which can freely control the operation of one of the processing tanks or filter the water simultaneously according to the needs. The guide pipe 6 is connected to the cold mold temperature controller, which can transport the filtered water to the cold mold temperature controller for cooling treatment to ensure the subsequent cooling treatment of the mold.

[0047] Also includes:

[0048] The filter bucket 7 is fixedly installed in the first processing tank 1 and the second processing tank 2 respectively. The outer circumferential wall of the filter bucket 7 is provided with a plurality of filter holes 8 distributed equidistantly in a circle. The filter bucket 7 can be divided into a plurality of chambers, namely an upper chamber 701, a middle chamber 702, and a lower chamber 703.

[0049] Preferably, the filter holes 8 are formed on the upper chamber 701 and the middle chamber 702, while the lower chamber 703 does not have filter holes 8. The diameters of the upper chamber 701 and the lower chamber 703 are larger than the diameter of the middle chamber 702. The lower chamber 703 is connected to the bottom of the treatment tank, and the bottom of the treatment tank is also provided with a discharge valve, through which impurities accumulated at the bottom of the treatment tank can be discharged.

[0050] Please see Figures 3-6 , Figure 8 A reciprocating driving mechanism is disposed within the filter barrel 7. An upper filter disc 16 and a lower filter disc 17 are connected to the reciprocating driving mechanism. The reciprocating driving mechanism can drive the upper filter disc 16 and the lower filter disc 17 to reciprocate along the length of the filter barrel 7. The reciprocating driving mechanism includes a rotating rod 9 rotatably mounted within the filter barrel 7. A spiral groove 901 is formed on the outer circumference of the rotating rod 9. Symmetrically arranged guide columns 10 are fixed within the filter barrel 7. The upper filter disc 16 and the lower filter disc 17 are slidably connected to the rotating rod 9 and the guide column 10, respectively. A guide assembly connected to the guide column 10 is provided on the rotating rod 9. The assembly includes a movable sleeve 11 slidably mounted on the rotating rod 9. A limiting block 14 is fixed on the inner wall of the movable sleeve 11 and slidably connected to the spiral groove 901. A connecting plate 12 is fixed on the movable sleeve 11 and slidably connected to the guide post 10. A driven structure connected to the lower filter disc 17 is provided on the movable sleeve 11. The driven structure includes a limiting groove 18 formed on the lower filter disc 17. A limiting ring 15 is fixed at the end of the movable sleeve 11 and slidably connected to the limiting groove 18. A first spring 13 is sleeved on the movable sleeve 11. The two ends of the first spring 13 abut against the connecting plate 12 and the upper filter disc 16, respectively.

[0051] In detail, to ensure that the filtered water does not accumulate impurities in the filter tank 7 and cause blockage of the filter holes 8 during filtration, the impurities need to be cleaned. Initially, the first spring 13 is compressed, and the limiting block 14 is located at the end of the stroke of the spiral groove 901 facing the top of the treatment tank. This causes the movable sleeve 11 to be located at the end of its stroke away from the bottom of the treatment tank. Under the action of the limiting groove 18 and the limiting ring 15, the lower filter disc 17 is controlled to be located in the upper chamber 701. Simultaneously, under the action of the conduction control mechanism, a certain control is maintained between the upper filter disc 16 and the lower filter disc 17. Also located in the upper chamber 701, since the upper filter plate 16 and the lower filter plate 17 are of similar size to the middle chamber 702, when located in the upper chamber 701, water can freely flow through the gap between the filter plate and the filter barrel 7 and enter the filter barrel 7. Since the upper filter plate 16 and the lower filter plate 17 are conical, when the water transported by the bidirectional conveying pipe 3 impacts the surface of the upper filter plate 16, it can wash away the impurities remaining on the upper filter plate 16 and the lower filter plate 17. The cooling water can be discharged through the filter hole 8 into the space between the filter barrel 7 and the treatment tank, and discharged through the bidirectional discharge pipe 5.

[0052] Preferably, when it is necessary to clean impurities, the rotating rod 9 rotates, driving the spiral groove 901 to move. Under the action of the spiral groove 901 and the limiting block 14, the movable sleeve 11 moves, thereby controlling the connecting plate 12 to move along the length direction of the guide post 10. The guide post 10 and the connecting plate 12 have a guiding function, ensuring that the movable sleeve 11 moves along the length direction of the rotating rod 9 and does not rotate with the rotating rod 9. The movable sleeve 11 also controls the upper filter disc 16 to move synchronously through the first spring 13, and under the action of the conduction control mechanism, causes the lower filter disc 17 to move synchronously. When both the upper filter disc 16 and the lower filter disc 17 detach from the upper chamber 701 and enter the middle chamber 702, the impurities located in the middle chamber 702 will always remain below the lower filter disc 17. Simultaneously, under the action of the flow control mechanism, cooling water can freely circulate within the filter tank 7. As the lower filter disc 17 moves, the impurities accumulated below it gradually increase until the lower filter disc 17 moves to the position where it engages with the impurity release component. Under pressure, the impurities remain between the lower filter disc 17 and the impurity release component, and the water is discharged to the lower filter disc through the flow control mechanism. Above 17, the control mechanism will also drive the upper filter disc 16 to move towards the lower filter disc 17 until the upper filter disc 16 and the lower filter disc 17 are tightly fitted together. At this time, the filter disc will be in a blocked state, ensuring that water will not flow below the lower filter disc 17. When the lower filter disc 17 engages with the impurity release component, the movable sleeve 11 continues to move and compresses the first spring 13. The movable sleeve 11 will also drive the limiting ring 15 to disengage from the limiting groove 18, and under the action of the limiting ring 15, the impurity release component will move. At this time, a gap will be formed between the lower filter disc 17 and the impurity release component, and the impurities will be released. The discharge assembly moves into the lower chamber 703. Under the action of gravity, impurities can be discharged into the lower chamber 703. After the impurities are discharged, the rotating rod 9 reverses, causing the movable sleeve 11 to move toward the initial position. The first spring 13 is released elastically, and the movable sleeve 11 will also drive the limiting ring 15 back into the limiting groove 18. After the limiting ring 15 is reset, under the action of the conduction control mechanism, the upper filter disc 16 moves away from the lower filter disc 17, the filter disc is turned on again, and moves toward the upper chamber 701. The above steps are repeated to achieve the effect of automatically cleaning impurities.

[0053] Please see Figures 5-9A conduction control mechanism is disposed on the upper filter disk 16 and connected to the lower filter disk 17. The conduction control mechanism can adjust the distance between the upper filter disk 16 and the lower filter disk 17 to adjust the conduction state between the upper filter disk 16 and the lower filter disk 17. The conduction control mechanism includes a support rod 19 fixedly installed on the lower filter disk 17 and passing through the upper filter disk 16. A support sleeve 21 is fixedly sleeved on the upper filter disk 16 and sleeved on the support rod 19. An elastic component connected to the support rod 19 is provided on the support sleeve 21. The elastic component includes an opening mechanism. A slot 22 is provided on the outer wall of the support sleeve 21. A fixing ring 20 is fixed on the support rod 19 and slidably connected to the slot 22. A second spring 23 is sleeved on the support sleeve 21 and abuts against the fixing ring 20. The lower filter plate 17 and the upper filter plate 16 are provided with a misalignment structure. The misalignment structure mentioned above includes a plurality of first discharge holes 1601 opened on the upper filter plate 16 and distributed equidistantly in a circle. A plurality of second discharge holes 1701 are opened on the lower filter plate 17 and distributed equidistantly in a circle. A scraper 24 that cooperates with the filter barrel 7 is fixed on the lower filter plate 17.

[0054] It should be noted that the scraper 24 is in contact with the inner wall of the middle chamber 702. In the initial state, the upper filter disc 16 and the lower filter disc 17 are located in the upper chamber 701, and the second spring 23 is in a compressed state, so that the support rod 19 is located at the end of its stroke away from the support sleeve 21, so that the fixing ring 20 is located at the end of its stroke on the side of the slot 22. At this time, the distance between the upper filter disc 16 and the lower filter disc 17 is the largest. Since the first discharge hole 1601 and the second discharge hole 1701 are misaligned, the discharge hole is open when the two filter discs are in a separated state. In this state, when impurities need to be cleaned, the rotating rod 9 rotates, and under the action of the spiral groove 901 and the limiting block 14, the movable sleeve 11 moves, thereby driving the upper filter disc 16 to move through the first spring 13. At the same time, under the action of the second spring 23, the lower filter disc 17 moves synchronously. When the lower filter disc 17 enters the middle chamber 702, the scraper 24 scrapes off the impurities remaining on the inner wall of the middle chamber 702. Since the discharge hole is in a conductive state, cooling water can freely enter the middle chamber 702 through the discharge hole. When the filter disc 17 moves to the position where it abuts against the impurity release component, the lower filter disc 17 stops moving, while the movable sleeve 11 continues to move. The first spring 13 controls the upper filter disc 16 to move towards the lower filter disc 17. The upper filter disc 16 also drives the support sleeve 21 to move, compressing the second spring 23. When the upper filter disc 16 moves to the position where it contacts the lower filter disc 17, the two discharge holes are misaligned, thus blocking the discharge holes. As the movable sleeve 11 moves, it also causes the limiting ring 15 to disengage from the limiting groove 18, driving the impurity release. The component moves to discharge impurities below the lower filter disc 17 into the lower chamber 703. After discharge, the movable sleeve 11 moves toward the initial position, causing the first spring 13 to release elastically and controlling the limiting ring 15 to return to the limiting groove 18. After the limiting ring 15 is reset, the movable sleeve 11 continues to move. At this time, the second spring 23 releases elastically and drives the upper filter disc 16 to move away from the lower filter disc 17, so that the discharge hole is opened again. This achieves the control of the discharge hole blockage during the impurity discharge process, ensuring that cooling water does not enter the lower chamber 703.

[0055] Please see Figure 5 , Figure 6 , Figure 10 An impurity release component is disposed inside the filter barrel 7 and connected to the reciprocating pushing mechanism. The reciprocating pushing mechanism can drive the impurity release component to move when the lower filter plate 17 cooperates with the impurity release component. The impurity release component includes a support ring 25 fixedly installed inside the filter barrel 7. A conical disk 26 that abuts against the support ring 25 is slidably installed on the rotating rod 9. A third spring 27 that abuts against the conical disk 26 is sleeved on the rotating rod 9.

[0056] Furthermore, in the initial state, the third spring 27 is compressed, causing the conical disk 26 to be in contact with the support ring 25. At this time, under the action of the conical disk 26 and the support ring 25, the lower chamber 703 is blocked. When the lower filter disk 17 moves towards the conical disk 26, the scraper 24 scrapes away impurities from the inner wall of the middle chamber 702. When the lower filter disk 17 moves to the position where it is in contact with the support ring 25, the lower filter disk 17 stops moving, and the movable sleeve 11 continues to move. The first spring 13 controls the upper filter disk 16 to move towards the lower filter disk 17 until the two filter disks are in contact with each other and the discharge hole is blocked. During this process, the lower part of the lower filter disk 17 will be in contact with the support ring 25. The upper part of the conical disc 26 is fitted and squeezed to ensure that the water in the impurities is squeezed out. At the same time, the movable sleeve 11 will also drive the limiting ring 15 to disengage from the limiting groove 18 and abut against the conical disc 26, thereby driving the conical disc 26 to move away from the lower filter disc 17, so that the third spring 27 is compressed. When the conical disc 26 disengages from the middle chamber 702 and enters the lower chamber 703, the impurities placed on the conical disc 26 will be detached from the conical disc 26 under the action of gravity and enter the lower chamber 703. After the impurities are released, the movable sleeve 11 returns to its original position, the third spring 27 is released elastically, and the conical disc 26 returns to its original position. The above steps are repeated to achieve the effect of automatically cleaning the filtered impurities.

[0057] The cooling and filtration system for injection molds includes the following steps:

[0058] Step 1: The cooling water in the water tank is transported to the first treatment tank 1 and the second treatment tank 2 through the feed pipe 4 and the bidirectional conveying pipe 3 respectively;

[0059] Step 2: The cooling water will be filtered through the filter hole 8, and under the action of the reciprocating push mechanism, the upper filter plate 16 and the lower filter plate 17 will move to clean the impurities in the filter barrel 7.

[0060] Step 3: When the lower filter disc 17 moves to the position where it engages with the impurity release component, the upper filter disc 16 and the lower filter disc 17 are brought into contact with each other by the control mechanism. At the same time, the impurity release component is controlled to move by the reciprocating pushing mechanism, so that the impurities placed below the lower filter disc 17 are discharged to the bottom of the filter barrel 7.

[0061] Step 4: The filtered cooling water is transported to the cold mold temperature controller through the bidirectional discharge pipe 5 and the guide pipe 6 for temperature control and cooling. After cooling, it is transported to the injection mold for cooling treatment.
