Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a cooling system device for improving the life of high-precision molds. Background Technology

[0002] High-precision molds refer to molds with extremely high manufacturing precision (usually reaching the micron level or even higher), excellent surface quality, and long service life. They are mainly used to produce products with extremely strict requirements for size, shape, and surface finish. Generally, straight holes are drilled in the mold and cooling water is introduced for cooling. However, this cooling method has low cooling efficiency and cannot make the mold cool evenly as a whole, resulting in temperature differences inside the mold and reducing the service life of high-precision molds. Utility Model Content

[0003] The purpose of this invention is to solve the problem that high-precision molds cannot be cooled evenly in the prior art, resulting in a reduced service life, and to propose a cooling system device to improve the service life of high-precision molds.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A cooling system device for improving the lifespan of high-precision molds includes a mold body, a water inlet and a water outlet for water circulation on one side of the mold body, and a cooling mechanism inside the mold body.

[0006] The cooling mechanism includes multiple S-shaped copper pipes installed inside the mold body. The two ends of the S-shaped copper pipes are connected to the water inlet and the drain outlet, respectively. The water inlet is located below the drain outlet. One end of the water inlet is connected to a water pump. A valve is installed inside the drain outlet. A flushing component is installed inside the S-shaped copper pipes.

[0007] Preferably, the flushing assembly includes a ball valve connected to one end of the S-shaped copper pipe near the water inlet. The mold body is provided with a first water passage hole, a second water passage hole and a third water passage hole. The first water passage hole, the second water passage hole and the third water passage hole are all connected to the S-shaped copper pipe. A conduit is provided between the first water passage hole and the third water passage hole. A connecting member is provided between the first water passage hole and the second water passage hole.

[0008] Preferably, the third water passage is located near the drain outlet of the S-shaped copper pipe, the first water passage and the second water passage are located near the water inlet of the S-shaped copper pipe, and one end of the second water passage extends through to the outside of the mold body.

[0009] Preferably, the conduit is provided with multiple sets of reflux grooves and guide grooves.

[0010] Preferably, the connecting member includes a first block and a second block that are slidably connected in the first water passage and the second water passage, respectively. A first spring is provided in both the first water passage and the second water passage. The two first springs are respectively connected to the first block and the second block. A frustum is slidably connected in the mold body. One end of the frustum is pressed and connected to the first block. A second spring is provided between the frustum and the mold body.

[0013] Compared with the prior art, this utility model provides a cooling system device to improve the life of high-precision molds, which has the following beneficial effects:

[0014] 1. This cooling system device for improving the life of high-precision molds increases the contact area between the cooling water and the mold body by filling the cooling water into the S-shaped copper pipe through the water inlet and draining it out through the drain outlet. The cooling water moves from bottom to top, increasing the contact time with the mold body, thereby improving the utilization rate of the cooling water.

[0015] 2. This cooling system device for improving the lifespan of high-precision molds works by closing the drain valve during the later stages of cooling. At this time, the cooling water pressure inside the S-shaped copper pipe forces open the first and second water passages, and the ball valve closes. The cooling water then flows into the pipe through the third water passage and is finally discharged from the second water passage, thus performing reverse flushing of the inside of the S-shaped copper pipe. This improves the cooling efficiency of the mold body and extends the service life of both the S-shaped copper pipe and the mold body. Attached Figure Description

[0024] Reference Figure 1-5 A cooling system device for improving the life of high-precision molds includes a mold body 1. A worker introduces a molten liquid workpiece into the mold, and the liquid workpiece fills the mold body 1 until it cools and solidifies. During this process, the heat of the liquid workpiece is conducted into the mold body 1. Cooling water is added from the water inlet 2 to accelerate the heat dissipation of the mold body 1 and the cooling of the liquid workpiece. A water inlet 2 and a drain 3 for water circulation are provided on one side of the mold body 1. A cooling mechanism 4 is provided inside the mold body 1, which can quickly dissipate the heat of the mold body 1 while reducing impurities generated in the mold body 1 when the cooling water evaporates, which is beneficial to improving the service life of the mold body 1.

[0025] The cooling mechanism 4 includes multiple S-shaped copper pipes 401 installed inside the mold body 1. Cooling water flows from the water inlet 2 at the bottom of the mold body 1 to the drain outlet 3 at the top, increasing the contact time between the cooling water and the mold body 1 and increasing the cooling efficiency of the mold body 1. The copper pipes have high heat transfer performance, which facilitates the absorption of heat from different locations inside the mold body 1. The two ends of the S-shaped copper pipes 401 are connected to the water inlet 2 and the drain outlet 3, respectively. The water inlet 2 is located below the drain outlet 3. One end of the water inlet 2 is connected to a water pump 402. The drain outlet 3 is equipped with a valve 403. When the water pump 402 is turned on, it can continuously introduce cooling water into the water inlet 2. When the valve 403 is open, water circulation is formed inside the mold body 1, which improves the cooling efficiency of the cooling water. The S-shaped copper pipes 401 are equipped with a flushing component 5, which can perform backflushing in the later stage of the cooling process. While the mold body 1 is being cooled normally, impurities generated inside the S-shaped copper pipes 401 are flushed, which improves the service life of the mold body 1.

[0026] The flushing assembly 5 includes a ball valve 501 connected to one end of the S-shaped copper pipe 401 near the water inlet 2. The ball valve 501 has a hollow structure in the middle, and its 90-degree rotation can stop and resume the flow of cooling water in the S-shaped copper pipe 401. The ball valve 501 is located between the first water inlet 502 and the second water inlet 503. When the ball valve 501 is closed, the water in the water inlet 2 enters the first water inlet 502 and the conduit 505 through a section of the S-shaped copper pipe 401, flows out through the third water inlet 504, re-enters the S-shaped copper pipe 401, and finally flows out of the mold body 1 through the second water inlet 503, thereby flushing the S-shaped copper pipe 401. The mold body 1 is equipped with a backwashing function to reduce impurities adhering to the inner wall of the S-shaped copper pipe 401 during the evaporation of cooling water. The mold body 1 has a first water passage 502, a second water passage 503, and a third water passage 504. The third water passage 504 is located near the drain outlet 3 of the S-shaped copper pipe 401. The first water passage 502 and the second water passage 503 are located near the water inlet 2 of the S-shaped copper pipe 401, and one end of the second water passage 503 extends to the outside of the mold body 1. All three water passages (502, 503, and 504) are connected to the S-shaped copper pipe 401. A conduit 505 is provided between the first water passage 502 and the third water passage 504. The conduit 505 connects the first water passage 502 and the third water passage 504, allowing the cooling water copper pipe to flow from one end of the drain outlet 3 to the second water passage 503 located at one end of the inlet 2. When the cooling water flows from the first water passage 502 to the third water passage 504, the cooling water is accelerated through the guide groove 507 and discharged into the S-shaped copper pipe 401 from the third water passage 504, thereby increasing the water flow impact force in the S-shaped copper pipe 401 and improving the efficiency of flushing impurities in the S-shaped copper pipe 401. Furthermore, the cooling water flows from the third water passage... When the cooling water flows from the third water passage 504 to the first water passage 502, it passes through the guide channel 507 and the return channel 506 at the same time, thereby blocking the cooling water in the guide channel 507 and restricting the cooling water from flowing from the third water passage 504 to the first water passage 502. The guide tube 505 is provided with multiple sets of return channels 506 and guide channels 507. The guide channels 507 are connected end to end, and the multiple sets of return channels 506 are interconnected and connected to the guide channels 507 in an orderly manner. A connecting piece 6 is provided between the first water passage 502 and the second water passage 503, which can keep the first water passage 502 and the second water passage 503 open or closed.

[0027] The connecting component 6 includes a first block 601 and a second block 602 slidably connected within the first water passage 502 and the second water passage 503, respectively. When the valve 403 is closed, the drain outlet 3 is closed, and the cooling water in the S-shaped copper pipe 401 applies water pressure to the first block 601 and the second block 602, compressing the first spring 603 to contract, thus opening the first water passage 502 and the second water passage 503. At this time, the ball valve 501 is closed, and backwashing begins on the S-shaped copper pipe 401. Both the first water passage 502 and the second water passage 503 are equipped with a first spring 603. With a large circular cavity, when the first block 601 and the second block 602 compress the first spring 603 and enter the cavity, the first water passage 502 and the second water passage 503 are open. When the valve 403 opens, the cooling water flows directly from the third water passage 504 to the drain outlet 3. At this time, the water pressure on the second block 602 decreases. The first spring 603 then pushes the first block 601 and the second block 602 to return to their original position, separating them from the cavity and closing the first water passage 502 and the second water passage 503 again. At this time, the ball valve 501 is open, and the cooling water can flow normally from the water inlet 2 to the drain outlet 3, ending the backwashing process. A spring 603 is connected to both a first block 601 and a second block 602. A ring-shaped trapezoidal groove 610 is formed on the surface of the first block 601. A guide groove 611 is formed on the surface of both the frustum 604 and the first block 601. A frustum 604 is slidably connected inside the mold body 1. A guide rod 608 is provided on one side of the frustum 604. A cross plate 609 is provided on one side of the ball valve 501. The cross plate 609 is rotatably connected to the mold body 1 and slidably connected to the guide rod 608. One end of the frustum 604 is pressed against the first block 601, and a second spring 605 is provided between the frustum 604 and the mold body 1. A first water passage 502 and a second water passage... A chute 606 is provided between blocks 503, and a crossbar 607 is provided between block 1 601 and block 2 602. When block 1 601 and block 2 602 are subjected to water pressure, the annular trapezoidal groove 610 on the surface of block 1 601 presses the guide groove 611 on the surface of frustum 604, causing frustum 604 to compress the second spring 605 and move linearly within the mold body 1. The guide rod 608 on one side of frustum 604 pushes cross plate 609 and ball valve 501 to rotate 90 degrees and be in a closed state, thus intercepting the cooling water in S-type copper pipe 401 and starting the backwashing operation of S-type copper pipe 401. The crossbar 607 slides linearly within the chute 606.

[0028] In this invention, when a liquid workpiece is injected into the mold body 1 and cooling begins, the water pump 402 pumps cooling water into the water inlet 2, through the S-shaped copper pipe 401, and out of the drain outlet 3. This causes the cooling water to flow upwards in an S-shape within the mold body 1, rapidly absorbing heat. Later in the cooling process, the valve 403 of the drain outlet 3 is closed. At this time, the water pressure pushes the first block 601 and the second block 602 to move, opening the first water passage 502 and the second water passage 503. Simultaneously, the guide rod 608 on one side of the frustum 604 pushes the cross plate 609 and the ball valve 501 to flip and close, thus blocking the cooling water in the S-shaped copper pipe 401. This allows the cooling water to flow from the water inlet 2 to the first water passage 502, and then through the conduit 505. The water flows out from the third water passage 504 and re-enters the S-shaped copper pipe 401, finally flowing out from the second water passage 503, completing the reverse flushing of the S-shaped copper pipe 401. At the end of cooling, the valve 403 of the drain outlet 3 is opened. At this time, the water pressure of the second block 602 decreases, and the second block 602, under the action of the first spring 603, contacts the first water passage 502 and the second water passage 503 again with the first block 601, keeping them in a closed state. The guide rod 608 on one side of the frustum 604 contacts the cross plate 609 again and rotates 90 degrees, so that the ball valve 501 and the S-shaped copper pipe 401 are in an open state, which facilitates the reuse of the mold body 1 and helps to improve the cooling efficiency of the mold while increasing the service life of the S-shaped copper pipe 401 and the mold body 1.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
