Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping forming, in particular to a water distributor capable of adjusting water flow. Background Art

[0002] In 1977, hot stamping technology was invented in Sweden. Hot stamping is referred to as hot forming. The hot forming steel plate (tensile strength of about 550MPa) is heated to above 900℃ in a heating furnace. The metallographic structure of the steel plate is transformed into austenite under high temperature. After the steel plate is heated and taken out of the furnace, it is stamped into shape at high temperature through a hot forming mold with a water cooling system. After forming, the mold is quickly cooled to below 100℃. The high-temperature austenite structure is transformed into martensite, which increases the tensile strength of the parts to more than 1300MPa. This process is the hot forming process.

[0003] In order to improve production efficiency, the thermoforming mold has multiple cavities in one mold. Each cavity can press different parts, so that multiple different parts can be produced with one stamping. The water distributor used in the thermoforming mold is a water distributor block made of steel blocks. The cooling water at the water inlet is diverted to multiple outlets through the water distributor of the water distributor block and flows to multiple mold cavities. It only has the function of diverting cooling water.

[0004] The disadvantages of the current mold water block method are:

[0005] Affected by the water pressure difference, the uneven internal resistance of each water pipe, and the different cross-sectional areas of the cooling water channels of each cavity, the average water flow rate (cubic decimeters / minute) of each cavity will be unbalanced, resulting in uneven cooling speed of each cavity.

[0006] Therefore, it is urgent to design a device that can adjust the water flow rate according to the requirements of each mold cavity, so that the average water flow rate (cubic decimeters / minute) of each cavity tends to be consistent, to ensure the uniform cooling rate of the hot forming mold, and to keep the dimensional performance of the parts stable to solve the above problems. Summary of the invention

[0007] The utility model aims to provide a water distributor with adjustable water flow rate, which can be adjusted according to the water flow rate required by the mold cavity to make the average water flow rate of the cavity tend to be consistent, ensure the uniform cooling speed of the hot forming mold, keep the dimensional performance of the parts stable, and optimize the overall production rhythm.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A water distributor capable of adjusting water flow, the water distributor comprises a main body, the main body is provided with a water inlet hole from one side inwardly, water outlet holes extending to the outside are provided on both sides of the water inlet hole, cooling water flows in through the water inlet hole and flows out through the water outlet holes into each mold cavity, and further comprises:

[0010] A water-dividing cavity, wherein the interior of the main body is hollow to form a water-dividing cavity;

[0011] The cooling water flows into the water distribution cavity through the water inlet hole and flows out through each group of water outlet holes;

[0012] An adjusting mechanism, wherein the adjusting mechanism is movably installed at the water outlet;

[0013] The regulating mechanism is rotated to cover the water outlet hole so that the water outlet hole is increased or decreased to control the cooling water flow.

[0014] Further, the adjustment mechanism has an adjustment bolt;

[0015] The adjusting bolt is provided with a through hole;

[0016] The adjusting bolt is rotated to form a through hole that is connected or partially connected with the water outlet hole.

[0017] Furthermore, a hexagonal slot is provided above the adjusting bolt;

[0018] The hexagonal wrench is inserted into the hexagonal slot and rotated to drive the adjusting bolt to rotate synchronously.

[0019] Furthermore, a groove is formed on the outer side of the adjusting bolt;

[0020] A first sealing ring is embedded in a portion of the groove;

[0021] The first sealing ring extends to the outside of a portion of the groove and fits on the inner wall of the main body.

[0022] Furthermore, a cover plate is installed above the main body;

[0023] The water diversion cavity extends upward to form an opening;

[0024] Two grooves are provided around the upper opening of the water diversion chamber;

[0025] A second sealing ring is embedded in the second part of the groove;

[0026] The second sealing ring extends to the outside of the second groove portion and is sealed and attached to the cover plate;

[0027] The adjusting bolt passes through the cover plate and is installed in the main body.

[0028] Furthermore, the cover plate is provided with a plurality of groups of bolt holes;

[0029] The bolts are screwed into the bolt holes to secure the cover plate to the main body.

[0030] In the above technical solution, the utility model has the following beneficial effects:

[0031] The utility model provides an optimized structure of a water distributor with adjustable water flow, which solves the defects of uneven diversion of cooling water and uncontrollable flow of the existing water distributor. By controlling the flow of the water diversion outlet, the flow of each outlet is uniform, so that the cooling speed of each mold cavity tends to be consistent, ensuring the stability of the part size performance, and when the flow is uniform, the cooling time can be guaranteed to be uniform, avoiding the problem of individual cavities cooling slowly, which leads to a longer cooling time of the entire mold, thereby optimizing the overall production rhythm.

[0048] A water distributor capable of adjusting water flow, comprising:

[0049] The water distributor comprises a main body 1, a water inlet 2 is provided from one side of the main body 1, water outlets 3 extending to the outside are provided on both sides of the water inlet 2, cooling water flows in through the water inlet 2 and flows out through the water outlets 3 to each mold cavity, and also comprises:

[0050] A water diversion chamber 11, the main body 1 is hollow inside to form a water diversion chamber 11;

[0051] The cooling water flows into the water distribution cavity 11 through the water inlet hole 2 and flows out through each group of water outlet holes 3;

[0052] The regulating mechanism 4 is movably mounted at the water outlet 3;

[0053] The regulating mechanism 4 is rotated to cover the water outlet hole 3 so that the water outlet hole 3 is increased or decreased to control the cooling water flow rate.

[0054] Specifically, a water distributor capable of adjusting water flow is provided with an adjusting mechanism 4 on the basis of an existing water distributor, and the adjusting mechanism 4 is distributed at each water outlet 3. By adjusting the adjusting mechanism 4, the water outlet 3 is enlarged or reduced, thereby adjusting the water flow through the water outlet 3.

[0055] Preferably, a flow valve may be installed at each water outlet 3 to monitor the water flow, so that the flow of each water outlet 3 can be controlled.

[0056] The adjustment mechanism 4 has an adjustment bolt 41;

[0057] The adjusting bolt 41 is provided with a through hole 411;

[0058] The through hole 411 is formed by rotating the adjusting bolt 41 and is connected or partially connected with the water outlet hole 3 .

[0059] Specifically, a through hole 411 is provided on the adjusting bolt 41 of the adjusting mechanism 4, and the adjusting bolt 41 is installed at the water outlet 3. When the through hole 411 of the adjusting bolt 41 is fully connected with the water outlet 3, the water flow is maximum. The adjusting bolt 41 is rotated so that the wall of the adjusting bolt 41 blocks part of the water outlet 3, the water outlet 3 becomes smaller, and the water flow decreases. When the wall of the adjusting bolt 41 completely blocks the water outlet 3, the water outlet 3 is closed and the water cannot flow out. The cooling water flow is controlled by adjusting the size of the water outlet 3 by rotating the adjusting bolt 41. In specific use, the water flow required for each mold cavity can be adjusted so that the average water flow (cubic decimeters / minute) of each cavity tends to be consistent, thereby ensuring that the cooling speed of the hot forming mold is uniform and the dimensional performance of the parts remains stable.

[0060] A hexagonal slot 412 is provided above the adjusting bolt 41;

[0061] The hexagonal wrench is inserted into the hexagonal slot 412 and rotated to drive the adjusting bolt 41 to rotate synchronously.

[0062] Specifically, the outer periphery of the adjusting bolt 41 is located in the main body 1 . When rotating the adjusting bolt 41 , a hexagonal wrench is used to align with the hexagonal slot 412 above the adjusting bolt 41 , and the hexagonal wrench is screwed to rotate the adjusting bolt 41 .

[0063] A groove portion 413 is formed on the outer side of the adjusting bolt 41;

[0064] A first sealing ring 5 is embedded in the groove portion 413;

[0065] The first sealing ring 5 extends to the outside of the groove portion 413 and fits on the inner wall of the main body 1 .

[0066] Specifically, a circle of grooves, namely, a groove portion 413, is provided on the outer periphery of the adjusting bolt 41, and a first sealing ring 5 is installed in the groove portion 413. The portion of the first sealing ring 5 located outside the groove portion 413 is attached to the inner wall of the main body 1. Even when the adjusting bolt 41 is rotated, the first sealing ring 5 can rub against the inner wall of the main body 1 to prevent the cooling water from flowing out, thereby having a certain sealing effect.

[0067] A cover plate 6 is installed above the main body 1;

[0068] The water diversion chamber 11 extends upward to form an opening;

[0069] Two grooves 12 are provided around the upper opening of the water diversion chamber 11;

[0070] A second sealing ring 7 is embedded in the second groove portion 12;

[0071] The second sealing ring 7 extends to the outside of the second groove portion 12 and is sealed and attached to the cover plate 6;

[0072] The adjusting bolt 41 passes through the cover plate 6 and is installed in the main body 1 .

[0073] Specifically, the open end of the water-dividing chamber 11 extends to the upper end of the main body 1, and the cover plate 6 is integrally covered on the top of the main body 1. In order to avoid a gap between the cover plate 6 and the upper wall of the main body 1, which may cause water to overflow when passing through, two groove parts 12 are provided on the upper end surface of the main body 1 around the open end of the water-dividing chamber 11, and a second sealing ring 7 is embedded in the two groove parts 12. Part of the second sealing ring 7 is located in the two groove parts 12, and the other part of the second sealing ring 7 is extruded to the outside of the second sealing ring 7. When the cover plate 6 is installed downwardly on the top of the main body 1, the cover plate 6 squeezes the second sealing ring 7 to form a seal therebetween, which is equivalent to forming a circle of sealing structure around the open end of the water-dividing chamber 11. When water flows through, the second sealing ring 7 can effectively prevent water from overflowing.

[0074] The cover plate 6 is provided with a plurality of bolt holes 61;

[0075] The bolts are screwed into the bolt holes 61 to achieve installation and fixation of the cover plate 6 and the main body 1 .

[0076] Specifically, the cover plate 6 is installed above the main body 1, and a plurality of bolt holes 61 are provided on the cover plate 6. Bolts are screwed into the bolt holes 61 until the cover plate 6 is fixedly installed on the main body 1. When disassembling, the bolts are screwed out and the cover plate 6 is removed.
