Description

Technical Field

[0001] The invention relates to the technical field of cooling filtration, in particular to a cooling filtration system based on an automatic slag cleaning filtration structure and an injection mold. Background Art

[0002] The cooling system of the mold is that 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 ends of each cooling pipeline inside the mold, flows out from the water outlet end and returns to the mold water outlet water collection module, and then returns to the temperature control and pumping equipment, thus forming a complete cooling circuit.

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

[0004] Existing coolant filtration usually transports the cooling water in the water tank to the filtering equipment, and filters the cooling water under the action of the filtering equipment. As the amount of cooling water filtered increases, the impurities in the filtering equipment gradually increase, which may cause the filter holes in the filtering equipment to be blocked. Since the existing filtering equipment cannot automatically discharge impurities, it is necessary to stop the filtering equipment for cleaning, which in turn affects the cooling of the injection mold.

[0047] Also includes:

[0048] The filter barrel 7 is fixedly installed in the first treatment tank 1 and the second treatment tank 2 respectively. The outer wall of the filter barrel 7 is provided with a plurality of filter holes 8 equidistantly distributed around the circumference. The filter barrel 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 provided on the upper chamber 701 and the middle chamber 702, and the filter holes 8 are not provided in the lower chamber 703. 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 processing tank, and a discharge valve is also provided at the bottom of the processing tank, through which impurities accumulated at the bottom of the processing tank can be discharged.

[0050] See also Figure 3-Figure 6 , Figure 8 , a reciprocating driving mechanism is arranged in the filter barrel 7, and 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 direction of the filter barrel 7. The reciprocating driving mechanism includes a rotating rod 9 rotatably installed in the filter barrel 7, and a spiral groove 901 is provided on the circumferential outer wall of the rotating rod 9. A symmetrically arranged guide column 10 is fixed in the filter barrel 7, and the upper filter disc 16 and the lower filter disc 17 are respectively slidably connected to the rotating rod 9 and the guide column 10, and a guide component connected to the guide column 10 is provided on the rotating rod 9, wherein the guide The component includes a movable sleeve 11 slidably mounted on the rotating rod 9, a limit block 14 slidably connected to the spiral groove 901 is fixed to the inner wall of the movable sleeve 11, a connecting plate 12 slidably connected to the guide column 10 is fixed to the movable sleeve 11, and a driven structure connected to the lower filter disc 17 is provided on the movable sleeve 11. The driven structure mentioned above includes a limit groove 18 opened on the lower filter disc 17, a limit ring 15 slidably connected to the limit groove 18 is fixed to the end of the movable sleeve 11, and a first spring 13 is sleeved on the movable sleeve 11, and the two ends of the first spring 13 are respectively abutted against the connecting plate 12 and the upper filter disc 16.

[0051] In detail, in order to ensure that the filter hole 8 will not be blocked due to the accumulation of filtered impurities in the filter barrel 7 during the filtering of the cooling water, the impurities need to be cleaned. In the initial state, the first spring 13 is in a compressed state, and the limit block 14 is located at the end of the stroke of the spiral groove 901 toward the top of the processing tank, so that the movable sleeve 11 is located at the end of the stroke away from the bottom of the processing tank. Under the action of the limit groove 18 and the limit ring 15, the lower filter disc 17 is controlled to be located in the upper chamber 701. At the same time, under the action of the conduction regulating mechanism, a certain control is left between the upper filter disc 16 and the lower filter disc 17, and Also located in the upper chamber 701, since the upper filter disc 16 and the lower filter disc 17 are of comparable size to the middle chamber 702, when located in the upper chamber 701, water can freely flow through the gap between the filter disc and the filter barrel 7 into the filter barrel 7, and since the upper filter disc 16 and the lower filter disc 17 are arranged in a conical shape, when the water transported by the two-way delivery pipe 3 impacts the surface of the upper filter disc 16, impurities remaining on the upper filter disc 16 and the lower filter disc 17 can be flushed away, and 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 two-way discharge pipe 5.

[0052] Preferably, when it is necessary to clean the impurities, the rotating rod 9 rotates and drives the spiral groove 901 to move. Under the action of the spiral groove 901 and the limit block 14, the movable sleeve 11 moves to control the connecting plate 12 to move along the length direction of the guide column 10. The guide column 10 and the connecting plate 12 have a guiding function to ensure 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 synchronous movement of the upper filter plate 16 through the first spring 13, and under the action of the conduction regulating mechanism, the lower filter plate 17 moves synchronously. When the upper filter plate 16 and the lower filter plate 17 are separated from the upper chamber 701 and enter the middle chamber 702, the impurities in the middle chamber 702 will always be located below the lower filter plate 17. At the same time, under the action of the conduction and regulation mechanism, the cooling water can flow freely in the filter barrel 7. As the lower filter plate 17 moves, the impurities accumulated below the lower filter plate 17 gradually increase until the lower filter plate 17 moves to the position where it cooperates with the impurity release component. Under the action of pressure, the impurities remain between the lower filter plate 17 and the impurity release component, and the water is discharged to the lower filter plate through the conduction and regulation mechanism. 17, the conduction regulating mechanism will also drive the upper filter plate 16 to move toward the lower filter plate 17 until the upper filter plate 16 and the lower filter plate 17 are tightly fitted. At this time, the filter plate will be in a blocked state to ensure that water does not flow to the bottom of the lower filter plate 17. When the lower filter plate 17 cooperates with the impurity release assembly, 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 assembly moves. At this time, a gap will be formed between the lower filter plate 17 and the impurity release assembly, and the impurity release assembly will not be released. The release assembly moves to the lower chamber 703, and under the action of gravity, impurities can be discharged into the lower chamber 703. After the impurities are discharged, the rotating rod 9 is reversed, so that the movable sleeve 11 moves toward the initial position, and the first spring 13 is elastically released. The movable sleeve 11 will also drive the limit ring 15 to return to the limit groove 18 again. When the limit ring 15 is reset, under the action of the conduction and regulation mechanism, the upper filter plate 16 moves away from the lower filter plate 17, the filter plate is turned on again, and moves toward the upper chamber 701, and the above steps are repeated, thereby achieving the effect of automatically cleaning the impurities.

[0053] See also Figure 5-Figure 9, a conduction regulating mechanism is arranged on the upper filter disc 16 and connected to the lower filter disc 17, and the conduction regulating mechanism can adjust the distance between the upper filter disc 16 and the lower filter disc 17 to adjust the conduction state of the upper filter disc 16 and the lower filter disc 17, and the conduction regulating mechanism includes a support rod 19 fixedly mounted on the lower filter disc 17 and passing through the upper filter disc 16, and a support sleeve 21 sleeved on the support rod 19 is fixed on the upper filter disc 16, and an elastic component connected to the support rod 19 is arranged on the support sleeve 21, wherein the elastic component includes an opening A slot 22 is provided on the outer wall of the support sleeve 21, a fixing ring 20 slidably connected to the slot 22 is fixed on the support rod 19, a second spring 23 abutting against the fixing ring 20 is sleeved on the support sleeve 21, and a staggered structure is provided on the lower filter disc 17 and the upper filter disc 16. The staggered structure mentioned above includes a plurality of first discharge holes 1601 opened on the upper filter disc 16 and distributed equidistantly around the circumference, a plurality of second discharge holes 1701 distributed equidistantly around the circumference are opened on the lower filter disc 17, and a scraper 24 cooperating with the filter barrel 7 is fixed on the lower filter disc 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 the stroke away from the support sleeve 21, so that the fixing ring 20 is located at the end of the stroke on one 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 staggered, when the two filter discs are in a separated state, the discharge holes are in a conducting state. When it is necessary to clean the impurities, the rotating rod 9 rotates, and under the action of the spiral groove 901 and the limit block 14, the movable sleeve 11 moves, so as to drive the upper filter plate 16 to move through the first spring 13. At the same time, under the action of the second spring 23, the lower filter plate 17 moves synchronously. When the lower filter plate 17 enters the middle chamber 702, under the action of the scraper 24, the impurities remaining on the inner wall of the middle chamber 702 are scraped off. Since the discharge hole is in the conducting state, the cooling water can freely pass through the discharge hole into the middle chamber 702. When the filter disc 17 moves to the position abutting against the impurity release component, the lower filter disc 17 stops moving, the movable sleeve 11 continues to move, and controls the upper filter disc 16 to move toward the lower filter disc 17 through the first spring 13. The upper filter disc 16 also drives the support sleeve 21 to move and compresses the second spring 23. When the upper filter disc 16 moves to the position abutting against the lower filter disc 17, the two discharge holes are staggered, so the discharge hole will be blocked. When the movable sleeve 11 moves, it will also drive the limit ring 15 to disengage from the limit groove 18 and drive the impurity release. The assembly moves to discharge impurities under the lower filter disc 17 into the lower chamber 703. When the discharge is completed, the movable sleeve 11 moves toward the initial position, so that the first spring 13 is elastically released, and the limiting ring 15 is controlled to return to the limiting groove 18. When the limiting ring 15 is reset, the movable sleeve 11 continues to move. At this time, the second spring 23 is elastically released and drives the upper filter disc 16 to move away from the lower filter disc 17, so that the discharge hole is conductive again, thereby achieving control of the discharge hole blocking during the impurity release process to ensure that cooling water does not enter the lower chamber 703.

[0055] See also Figure 5 , Figure 6 , Fig.10 The impurity release component is arranged in the filter barrel 7 and connected to the reciprocating driving mechanism. The reciprocating driving 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 in the filter barrel 7, and a conical disk 26 that abuts against the support ring 25 is slidably installed on the rotating rod 9. The rotating rod 9 is provided with a third spring 27 that abuts against the conical disk 26.

[0056] Further, in the initial state, the third spring 27 is in a compressed state, so that the conical disk 26 is located in a position that fits 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 in a blocked state. When the lower filter disk 17 moves toward the conical disk 26, the impurities on the inner wall of the middle chamber 702 are scraped off by the scraper 24. When the lower filter disk 17 moves to the position that fits with the support ring 25, the lower filter disk 17 no longer moves, and the movable sleeve 11 continues to move, and controls the upper filter disk 16 to move toward the lower filter disk 17 through the first spring 13, until the two filter disks fit each other and the discharge hole is in a blocked state. 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 disk 26 fits and squeezes the impurities 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 disk 26, thereby driving the conical disk 26 to move in a direction away from the lower filter disk 17, so that the third spring 27 is compressed. When the conical disk 26 disengages from the middle chamber 702 and enters the lower chamber 703, the impurities placed on the conical disk 26 will be separated from the conical disk 26 under the action of gravity and enter the lower chamber 703. When the impurities are released, the movable sleeve 11 is reset, and the third spring 27 is elastically released, so that the conical disk 26 is reset, and the above steps are repeated, thereby achieving the effect of automatically cleaning the filtered impurities.

[0057] The cooling and filtration system of the injection mold includes the following steps:

[0058] Step 1: transport the cooling water in the water tank to the first treatment tank 1 and the second treatment tank 2 through the feed pipe 4 and the two-way delivery pipe 3 respectively;

[0059] Step 2: The cooling water will be filtered through the filter hole 8, and under the action of the reciprocating driving mechanism, the upper filter plate 16 and the lower filter plate 17 are controlled to 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 cooperates with the impurity release assembly, the upper filter disc 16 and the lower filter disc 17 are fitted with each other under the action of the conduction regulating mechanism. At the same time, under the action of the reciprocating driving mechanism, the impurity release assembly is controlled to move, so that the impurities placed under 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 two-way discharge pipe 5 and the guide pipe 6 for temperature control cooling, and after cooling, it is transported to the injection mold to cool the mold.
