Technical Field
[0001] This utility model relates to the field of aluminum alloy die casting mold technology, and in particular to a multi-stage cooling aluminum alloy die casting mold. Background Technology
[0002] Aluminum alloy die casting mold is a tool used to inject molten aluminum alloy under high pressure into a mold cavity, and after cooling and solidification, form metal parts of a specific shape and size.
[0003] Patent CN219402277U discloses an aluminum alloy die-casting mold with high-efficiency cooling function. It includes a movable block, with a left die-casting block movably fitted to the center of one side of the movable block's front. The left die-casting block has a left connecting hole inside. A right die-casting block is movably fitted to the center of the other side of the movable block's front, with a right connecting hole inside. An upper die-casting block is movably fitted to the center of the top of the movable block's front, with an upper push rod movably connected to the center of the top of the upper die-casting block. A lower die-casting block is movably fitted to the center of the bottom of the movable block's front. When using this patent, cooling water is sprayed onto the center of the opposite die-casting module using two cooling spray guns. However, the angle of the cooling spray guns in the aforementioned prior art is fixed, and the movable mold plate is obstructed by the die-casting parts, which can easily lead to inconsistent cooling rates in different parts of the components within the movable block and mounting block, resulting in uneven internal stress distribution and the risk of component deformation and cracking.
[0004] Therefore, there is a need to provide a multi-stage cooling aluminum alloy die-casting mold. Utility Model Content
[0005] To overcome the shortcomings of existing patents where the angle of the cooling spray gun is fixed and the moving mold plate is blocked by the die-casting part, which easily leads to inconsistent cooling rates in different parts of the components within the moving block and mounting block, resulting in uneven internal stress distribution and the risk of component deformation and cracking, this utility model provides a multi-stage cooling aluminum alloy die-casting mold. Through components such as guide rods, spray cylinders, and nozzles, multi-stage segmented spraying can be performed on the interior of the mold, thereby ensuring all-round cooling of the interior of the mold.
[0006] To address the aforementioned issues, this utility model employs the following technical solution: a multi-stage cooling aluminum alloy die-casting mold, comprising a base, a first electric guide rail, a first mold, and a second mold. Two first electric guide rails are installed within the base, the first mold is installed between the two first electric guide rails, and the second mold is installed between the two first electric guide rails. The first mold and the second mold slide along the two first electric guide rails. The mold also includes a mounting base, a guide rod, a screw, a motor, a slide block, a spray cylinder, nozzles, a connecting pipe, and a water pump. A mounting base is fixedly connected to the first mold, a guide rod is fixedly connected to the mounting base, and a motor is mounted on the mounting base. A screw is connected to the output shaft of the motor via a coupling. A slide block is threaded onto the screw, and the slide block slides along the guide rod. A spray cylinder is fixedly connected to the slide block, and three sets of nozzles are fixedly connected and connected to the spray cylinder. A water pump is mounted on the spray cylinder, and a connecting pipe is connected to the water pump.
[0007] Optionally, it also includes a cooling pool and a water tap, with the cooling pool fixedly connected to the base and the water tap installed on the cooling pool.
[0008] Optionally, it also includes a feeding plate, gears, second electric guide rails, a sliding frame, and racks. Two second electric guide rails are installed on the cooling pool, and a sliding frame is installed between the two second electric guide rails. The sliding frame slides on the two second electric guide rails, and multiple racks are fixedly connected to the top of the sliding frame. Multiple gears are rotatably arranged on the cooling pool, and the gears mesh with adjacent racks. A feeding plate is fixedly connected between two gears.
[0009] Optionally, it also includes limiting plates, with two limiting plates fixedly connected to the cooling pool.
[0010] Optionally, multiple guide pillars are fixedly connected to the second mold.
[0011] Optionally, a filter screen is fixedly connected to the feeding plate.
[0012] Optionally, four reinforcing ribs are fixedly connected to the base.
[0013] Optionally, the base has four mounting holes.
[0014] Compared with the prior art, the present invention has the following technical effects: 1. By starting the water pump, the water pump draws water from the external water pipe and the connecting pipe, so that the water enters the spraying cylinder and sprays out from the nozzle. Then, the motor is started, and the output shaft of the motor drives the screw to rotate. The screw drives the slide and the spraying cylinder to move, so that the spraying cylinder sprays the inside of the first mold and the second mold in all directions and in multiple stages, thereby ensuring that the inside of the mold is cooled in all directions and avoiding the mold from cracking due to local stress concentration.
[0015] 2. By operating the second electric guide rail, the electric slider on the second electric guide rail drives the sliding frame to move downward. The sliding frame drives the four racks to move downward. The racks mesh with the gears, causing the feeding plate to rotate and drive the casting on it to move downward. This allows the casting to slowly enter the cooling pool, thus preventing the casting from falling directly into the cooling pool and causing damage. Attached Figure Description

Detailed Implementation
[0024] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.
[0025] Example 1: A multi-stage cooling aluminum alloy die-casting mold, see reference. Figures 1-6As shown, the system includes a base 1, a first electric guide rail 2, a first mold 3, and a second mold 4. The first electric guide rail 2 is bolted to both the upper left and right sides of the base 1. The first mold 3 is installed between the two electric sliders of the two first electric guide rails 2, and the second mold 4 is installed between the two electric sliders of the two first electric guide rails 2. The first mold 3 and the second mold 4 slide on the two first electric guide rails 2, and the first mold 3 engages with the second mold 4, with the first mold 3 located in front of the second mold 4. The system also includes a mounting base 7, a guide rod 8, a screw 9, a motor 10, a slide block 11, a spray cylinder 12, a nozzle 13, and a connecting... Pipe 14 and water pump 15 are fixedly connected to the first mold 3. A mounting base 7 is fixedly connected to the first mold 3. A guide rod 8 is set on the right side of the mounting base 7 by welding. A motor 10 is set on the left side of the mounting base 7 by bolt connection. A screw 9 is connected to the output shaft of the motor 10 by a coupling. A slide 11 is threaded on the screw 9. The slide 11 slides on the guide rod 8. A spray cylinder 12 is fixedly connected to the slide 11. Three sets of nozzles 13 are fixedly connected and connected to the front and rear sides of the spray cylinder 12 at even intervals. The three nozzles 13 form a group. Each group of nozzles is arranged in a fan shape. A water pump 15 is installed on the top of the spray cylinder 12. A connecting pipe 14 is connected to the water pump 15.
[0026] See Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, it also includes a cooling pool 5 and a water tap 6. The cooling pool 5 is fixedly connected to the lower part of the base 1, and the water tap 6 is installed on the left side of the middle part of the cooling pool 5.
[0027] See Figure 3 As shown, multiple guide pillars are fixedly connected to the second mold 4, so that the first mold 3 and the second mold 4 are snapped together.
[0028] See Figures 1-4 As shown, four reinforcing ribs are fixedly connected to the base 1 to enhance its stability.
[0029] See Figures 1-4 As shown, the base 1 has four mounting holes to facilitate the installation of equipment.
[0030] When die casting is to be performed, molten metal is first injected into the first mold 3 and the second mold 4, allowing the first mold 3 and the second mold 4 to die-cast and shape the molten metal. After shaping, the two first electric guide rails 2 are activated, causing multiple electric sliders on the two first electric guide rails 2 to drive the first mold 3 and the second mold 4 to move outward, causing the castings in the first mold 3 and the second mold 4 to fall into the cooling pool 5 for cooling. When the mold needs to be cooled, the external water pipe is connected to the connecting pipe 14, and then the water pump 15 is started, causing the water pump 15 to draw water from the external water pipe and the connecting pipe 14, allowing the water to enter the spray nozzle. 12 is sprayed from nozzle 13, and then motor 10 is started. The output shaft of motor 10 drives screw 9 to rotate. Screw 9 drives slide 11 and spray cylinder 12 to move, so that spray cylinder 12 sprays the inside of the first mold 3 and the second mold 4 in all directions and in multiple stages, thereby ensuring all-round cooling of the inside of the mold and preventing the mold from cracking due to local stress concentration. After cooling is completed, water pump 15 and motor 10 are turned off, and then subsequent casting operations can be carried out. When it is necessary to replace the cooling water, turn water tap 6 to drain the water from water tap 6. After draining, turn off water tap 6 and then pour clean water into cooling pool 5.
[0031] Example 2: Based on Example 1, refer to Figure 1 , Figure 6 and Figure 7 As shown, it also includes a feeding plate 16, a gear 17, a second electric guide rail 18, a sliding frame 19, and a rack 20. The cooling pool 5 is equipped with second electric guide rails 18 on both the front and rear sides by bolt connection. A sliding frame 19 is installed between the two electric sliders of the two second electric guide rails 18. The sliding frame 19 slides on the two second electric guide rails 18. The top of the sliding frame 19 is equipped with racks 20 on both the front and rear sides by welding. The cooling pool 5 is equipped with gears 17 on both the front and rear sides by rotation. The gears 17 mesh with the adjacent racks 20. The feeding plate 16 is fixedly connected between the two gears 17. The two feeding plates 16 are located on the left and right sides inside the cooling pool 5.
[0032] See Figure 1 , Figure 6 and Figure 7 As shown, it also includes a limiting plate 21. The left and right sides of the cooling pool 5 are fixedly connected to the limiting plate 21, which can limit the position of the casting on the two feeding plates 16.
[0033] See Figure 1 , Figure 6 and Figure 7 As shown, a filter screen is fixedly connected to the feeding plate 16 to ensure that the casting is in contact with the water in the cooling pool 5.
[0034] Before cooling the casting, the two second electric guide rails 18 are activated. The electric sliders on the second electric guide rails 18 drive the sliding frame 19 to move upward. The sliding frame 19 drives the four racks 20 to move upward. The racks 20 mesh with the gears 17. As the gears 17 rotate, they drive the two feeding plates 16 to rotate, making the two feeding plates 16 parallel. After the casting separates from the first mold 3 and the second mold 4, the casting falls onto the two feeding plates 16. Then, the second electric guide rails 18 are operated, causing the electric sliders on the second electric guide rails 18 to drive the sliding frame 19 to move downward. The sliding frame 19 drives the four racks 20 to move downward. The racks 20 mesh with the gears 17, causing the feeding plates 16 to rotate and move the castings on them downward, so that the casting slowly enters the cooling pool 5, thereby avoiding the casting from falling directly into the cooling pool 5 and being damaged.
[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
