Description

Technical Field

[0001] The invention relates to the field of injection mold cooling, and in particular to a water discharge control structure of an injection mold cooling system. Background Art

[0002] Injection molding is an efficient production process that is widely used in the manufacture of parts in the fields of automobiles, home appliances, etc. During the injection molding process, the control of mold temperature is the key to ensuring the quality of the finished product and production efficiency. The cooling system can quickly dissipate the heat generated by the molten plastic during the solidification molding process, thereby shortening the cooling time and improving production efficiency. One of the design principles of the cooling water row control structure is to achieve uniform cooling of the mold. In order to achieve this goal, the layout of the cooling water channel needs to follow certain rules. First, the distance between the cooling water channel and the surface of the mold cavity should be roughly equal to ensure that the temperature of each part of the mold cavity is roughly balanced. During the operation of the existing injection mold cooling system water row, the main function is to evenly distribute the cooling water flow to multiple tributary waterways. However, after the cooling water channel of the injection mold is used continuously for a period of time, a certain amount of scale will inevitably accumulate on the inner wall of the cooling water channel. If the scale is not cleaned in time, this will not only weaken the cooling efficiency of the device, but also slow down the water flow rate due to the presence of scale, which will cause the internal water pressure to increase abnormally, and there is a potential risk of pipe bursting.

Before cleaning, the staff rotates the three-hole ball valve 7 180 degrees, wherein a rotating rod 39 is welded on the top of the three-hole ball valve 7, and a screw head 40 is welded on the top of the rotating rod 39, and the screw head 40 is provided for the convenience of twisting the rotating rod 39 and the three-hole ball valve. The hole ball valve 7 rotates; then the staff adds an appropriate amount of iron sand into the inner cavity of the feeding shell 13 through the feeding pipe 14, and the motor 2 15 drives the spiral feeding paddle 16 to rotate, and the rotating spiral feeding paddle 16 pushes the iron sand to the return port 43 at the bottom of the feeding pipe; two partitions 10 are welded on the inner circumferential wall of the two mounting cylinders 9, and the top of the inner cavity of the two mounting cylinders 9 is fixedly installed with a motor 11, and the bottom output end of the two motors 11 is fixedly installed with a rotating block 12, and the iron sand falls through the return port 43 into the gap formed between the notch of the rotating block 12 and the inner wall of the mounting cylinder 9. As the motor 11 drives the rotating block 12 to rotate, the iron sand in the above-mentioned gap is pushed to the notch of the bottom partition 10, and enters the water inlet pipe 8 through the notch of the bottom partition 10.

[0034] Furthermore, one end of the return water splitter 5 away from the return water hole 3 is connected to a return water pipe 17, and one end of the return water pipe 17 away from the return water splitter 5 is connected to a mounting cylinder 2 18, a filter screen 19 is provided at the connection between the mounting cylinder 2 18 and the return water pipe 17, a feed pipe 20 is connected between the mounting cylinder 2 18 and the feed shell 13, a motor 3 21 is fixedly installed on the top of the mounting cylinder 2 18, a column 22 is fixedly installed on the bottom output end of the motor 3 21, a circular plate 23 is welded on the outer peripheral wall of the column 22, a plurality of push plates 24 are welded at equal intervals on the bottom of the circular plate 23, a plurality of magnet rods 25 are fixedly welded at equal intervals on the bottom of the circular plate 23, and each magnet rod 25 are located between every two push plates 24 in a one-to-one correspondence. The filter screen 19 is arranged to intercept the iron sand and the cleaned dirt in the inner cavity of the installation cylinder 18, wherein the magnet rod 25 is arranged to adsorb the iron sand, which reduces the probability of the iron sand clogging the filter screen 19 to a certain extent; the motor 3 21 is arranged to drive the column 22 to rotate, and the column 22 drives the circular plate 23, the push plate 24 and the magnet rod 25 to rotate, and the push plate 24 is arranged to push the dirt on the top of the filter screen 19 to the back of the inner cavity of the installation cylinder 18, and the above-mentioned sludge enters the inner cavity of the conveying shell 13 through the discharge pipe 20 connected with the conveying shell 13 by the installation cylinder 18.

[0035] Furthermore, a slide groove 26 is provided on the outer peripheral wall of the mounting cylinder 18, and a plurality of slide rods 27 are slidably arranged in the slide groove 26. A piston plate 28 is welded to the bottom of each slide rod 27, and each piston plate 28 is located one-to-one between every two push plates 24, and each piston plate 28 is slidably arranged one-to-one on the outer peripheral wall of each magnet rod 25. When the magnet rod 25 rotates, it will drive the piston plate 28 and the slide rod 27 to rotate. When the slide rod 27 rotates to the back of the mounting cylinder 18, the set slide rod 27 will move downward along the trajectory of the slide groove 26 on the back of the mounting cylinder. At the same time, the set slide rod 27 will push the piston plate 28 to move downward. The downward piston plate 28 can scrape off the iron sand adsorbed on the outer peripheral wall of the magnet rod 25, so that the iron sand also enters the inner cavity of the feed shell 13 through the discharge pipe 20 connected to the feed shell 13 through the mounting cylinder 18.

[0036] Furthermore, a motor 29 is fixedly mounted on the side wall of the feed shell 13, a reciprocating screw 30 is fixedly mounted on the output end of the motor 29, a mounting shell 31 is threadedly connected to the outer peripheral wall of the reciprocating screw 30, the motor 29 drives the reciprocating screw 30 to rotate, the reciprocating screw 30 drives the mounting shell 31 to perform reciprocating motion, and a strong electromagnet 36 arranged inside the mounting shell 31 can adsorb iron sand in the sludge to the bottom of the mounting shell 31, so that the iron sand is separated from the sludge; wherein, a limiting rod 37 is welded between the side walls at both ends of the inner cavity of the feed shell 13, and the mounting shell 31 is slidably arranged on the outer peripheral wall of the limiting rod 37, and the limiting rod 37 is set to limit the mounting shell 31 during the movement.

[0037] Furthermore, a reciprocating screw rod 32 is rotatably connected to the inner cavity of the mounting shell 31, and gears 33 are welded on the side walls at both ends of the reciprocating screw rod 32. Racks 34 are welded on the side walls at both ends of the inner cavity of the feed shell 13, and the two racks 34 mesh with the two gears 33 in a one-to-one correspondence. A mounting block 35 is threadedly connected to the outer peripheral wall of the reciprocating screw rod 32, and an electromagnet 36 is fixedly installed at the bottom of the mounting block 35. The gear 33 that moves linearly with the mounting shell 31 rotates under the action of the rack 34, and the rotating gear 33 drives the reciprocating screw rod 32 to rotate, and the rotating reciprocating screw rod 32 32 drives the mounting block 35 and the powerful electromagnet 36 to move back and forth left and right; due to the constant change in the position of the powerful electromagnet 36, the iron sand adsorbed on the bottom of the mounting shell 31 will also move with the powerful electromagnet 36, and the iron sand will rub against each other during the movement, which makes the sludge adhered to the surface of the iron sand be wiped off during the friction between the iron sand; wherein, a limiting rod 2 38 is welded between the side walls at both ends of the inner cavity of the mounting shell 31, and the mounting block 35 is slidably set on the outer peripheral wall of the limiting rod 2 38, and the set limiting rod 2 38 limits the mounting block 35 during the movement.

[0038] Furthermore, a sewage outlet 41 is opened at the bottom of the feed pipe, a sewage box 42 is fixedly installed on the side wall of the water drain body 1, and the feed end of the sewage box 42 is connected to the sewage outlet 41. The rotating spiral feed blade 16 transports the sludge to the sewage outlet 41 at the bottom of the feed shell 13, so that the sludge falls into the sewage box 42 through the sewage outlet 41.

[0039] Working principle: Before use, the output end and input end of the chiller water tank are connected to the water inlet hole 2 and the water return hole 3 of the water drain body 1 respectively, and then the water inlet pore 4 and the water return pore 5 are connected to the cooling water path of the injection mold by means of a pipeline; when in use, the cooling water flows out of the cooling water tank and flows into the water inlet pore 4 through the water inlet hole 2, and then enters the cooling water path of the injection mold through the pipeline, and finally the cooling water that has completed the cooling operation flows back into the cooling water tank through the water return pore 5 and the water return hole 3;

[0040] After being used for a period of time, impurities such as scale will be generated on the inner wall of the cooling water channel of the injection mold. If they are not cleaned in time, such impurities will reduce the cooling effect of the cooling water. Before cleaning the above-mentioned impurities such as scale, the staff twists the three-hole ball valve 7 180 degrees. It should be noted that a direct current hole and a diversion hole are provided on the side wall of the three-hole ball valve 7, and the direct current hole and the diversion hole are interconnected. When the three-hole ball valve 7 is rotated 180 degrees, the diversion hole is aligned with the air hole 6. Subsequently, the staff adds an appropriate amount of iron sand to the inner cavity of the feed shell 13 through the feeding pipe 14. When cleaning the above-mentioned impurities such as scale, the external water supply mechanism delivers cleaning water to the inside of the water drain body 1, and the external air pump delivers high-pressure gas to the inside of the water drain body 1 through the air hole 6. In addition, the motor 2 15 is set to drive the spiral feed paddle 16 to rotate, and the rotating spiral feed paddle 16 pushes the iron sand to the return port 43 at the bottom of the feed pipe, and the iron sand falls to the rotating block 12 through the return port 43. In the gap formed between the notch and the inner wall of the installation cylinder 9, as the motor 11 drives the rotating block 12 to rotate, the iron sand in the above-mentioned gap is pushed to the notch of the bottom partition 10, and enters the water inlet pipe 8 through the notch of the bottom partition 10; the high-pressure gas and high-pressure water combine to form a water-vapor mixed flow, in which the bubbles will burst under the action of pressure, and the impact energy generated acts on the iron sand, so that the iron sand forms an impact effect similar to a cannonball flow and acts on the inner wall of the pipe, thereby effectively removing dirt; it should be noted that the notches of the two partitions 10 inside a single installation cylinder 9 are arranged in a staggered manner, and the iron sand enters the gap formed between the notch of the top partition 10 and the inner wall of the installation cylinder 9 from the notch of the rotating block 12, and then the rotating rotating block 12 pushes the iron sand in the gap to the notch of the bottom partition 10, which makes the feed pipe and the water inlet pipe 8 not directly connected, which to a certain extent avoids the water flow and gas in the water inlet pipe 8 from entering the feed pipe;

[0041] After the cleaning operation is completed, the water flows into the inner cavity of the second installation cylinder 18 through the pipe on the outer peripheral wall of the second installation cylinder 18, and then the water flows into the return pipe 17, the return water splitter 5 and the return water hole 3 in sequence through the filter screen 19, so as to carry out the next cleaning operation; the set filter screen 19 intercepts the iron sand and the cleaned dirt in the inner cavity of the second installation cylinder 18, wherein the set magnet rod 25 can adsorb the iron sand, which reduces the probability of the iron sand blocking the filter screen 19 to a certain extent; at the same time, the set motor 3 21 drives the column 22 to rotate, and the column 22 drives the circular plate 23, the push plate 24 and the magnet rod 25 to rotate, and the set push plate 24 pushes the dirt on the top of the filter screen 19 to the back of the inner cavity of the second installation cylinder 18, and the above-mentioned sludge is connected with the feed shell 13 through the second installation cylinder 18. The connected feed pipe 20 enters the inner cavity of the feed shell 13; at the same time, when the magnet rod 25 rotates, it will drive the piston plate 28 and the slide bar 27 to rotate. When the slide bar 27 rotates to the back of the mounting cylinder 18, the set slide bar 27 will move downward along the trajectory of the slide groove 26 on the back of the mounting cylinder. At the same time, the set slide bar 27 will push the piston plate 28 to move downward. The downward piston plate 28 can scrape off the iron sand adsorbed on the outer peripheral wall of the magnet rod 25, so that the iron sand also enters the inner cavity of the feed shell 13 through the mounting cylinder 18 and the feed shell 13. It should be noted that a plastic part is provided at the bottom of the magnet rod 25, which makes it difficult for the iron sand scraped off by the piston plate 28 to adhere to the bottom of the magnet rod 25, so that the magnet rod 25 can smoothly enter the inner cavity of the feed shell 13;

[0042] Subsequently, the motor 2 15 and the motor 4 29 are operated simultaneously, and the motor 2 15 drives the spiral feed paddle 16 to rotate, and the rotating spiral feed paddle 16 pushes the sludge to move in the direction of the sewage outlet 41. At the same time, the motor 4 29 drives the reciprocating screw 1 30 to rotate, and the reciprocating screw 1 30 drives the mounting shell 31 to perform reciprocating motion, and the strong electromagnet 36 arranged inside the mounting shell 31 can adsorb the iron sand in the sludge to the bottom of the mounting shell 31, so that the iron sand is separated from the sludge; at the same time, due to the meshing of the gear 33 and the rack 34, the gear 33 that moves linearly with the mounting shell 31 rotates under the action of the rack 34, and the rotating gear 33 drives the reciprocating screw 2 32 to rotate, and the rotating reciprocating screw 2 32 drives the mounting block 35 and the strong electromagnet 36 to reciprocate left and right; since the position of the strong electromagnet 36 is not The iron sand adsorbed on the bottom of the mounting shell 31 will also move with the powerful electromagnet 36. During the movement, the iron sand will rub against each other, so that the sludge adhered to the surface of the iron sand will be wiped off during the friction between the iron sand. The rotating spiral feeding blade 16 transports the sludge to the sewage outlet 41 at the bottom of the feeding shell 13, so that the sludge falls into the sewage box 42 through the sewage outlet 41. When the reciprocating screw 30 is set to transfer the powerful electromagnet 36 to the position between the sewage outlet 41 and the return port 43, the external controller controls the external power supply to stop supplying power to the powerful electromagnet 36. After stopping the power supply, the magnetic force of the electromagnet 36 is rapidly weakened, and the iron sand adsorbed on the bottom of the mounting shell 31 falls to the bottom of the inner cavity of the feeding shell 13. Then, the rotating spiral feeding blade 16 transfers the iron sand to the return port 43, so that the iron sand is cleaned again, thereby realizing the recycling of the iron sand.

[0043] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
