Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold processing technology, and in particular to an extrusion mold with a high-efficiency heat dissipation structure. Background Technology
[0002] During the use of extrusion dies, a large amount of heat is generated when metal materials are extruded and formed. If the heat cannot be dissipated in a timely and effective manner, the die temperature will become too high.
[0003] Excessive temperature can not only affect the service life of the mold, causing defects such as cracks and deformation due to thermal fatigue, but also affect the quality of the extruded product, such as leading to a decrease in product dimensional accuracy and an increase in surface roughness.
[0004] In the past, the traditional heat dissipation methods of extrusion dies were quite simple and rudimentary, mostly relying on natural cooling or simply using a straight-through water channel for heat dissipation. This method resulted in the heat not being dissipated quickly and fully. With the development of modern manufacturing, the requirements for heat dissipation efficiency and processing accuracy of dies have become increasingly stringent. Traditional heat dissipation methods cannot ensure that the dies work at a suitable temperature, which makes it difficult to meet the strict requirements for the stability and accuracy of dies when producing high-precision products, thus limiting the improvement of production efficiency and product quality.
[0005] Therefore, this utility model proposes an extrusion die with a high-efficiency heat dissipation structure. Utility Model Content
[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and propose an extrusion die with a high-efficiency heat dissipation structure.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: an extrusion die with a high-efficiency heat dissipation structure, comprising:
[0008] An extrusion die assembly, comprising a lifting base and two extrusion die cylinders, the two extrusion die cylinders being rotatably connected to the top of the lifting base, and both extrusion die cylinders having cooling holes;
[0009] A cooling assembly, comprising a cooling sleeve sleeved on the outside of the extrusion die assembly, a mounting base provided at the bottom of the cooling sleeve, and a threaded cooling pipe and a cooling ring tube bracket embedded in the cooling sleeve and passing through the mounting base.
[0010] A water tank assembly, comprising a water tank barrel disposed below a mounting base, a support rod disposed between the water tank barrel and the mounting base, a hydraulic push rod disposed on the top of the water tank barrel that passes through the mounting base and connects to a lifting base, a partition disposed inside the water tank assembly, a first water pump fixedly connected to one side of the partition in the water tank barrel, and a second water pump fixedly connected to the other side of the partition in the water tank barrel;
[0011] The cooling assembly consists of a cooling barrel and a rotating blade. The rotating blade is rotatably connected between the cooling barrel and the water tank. A drive motor and a mounting bracket are provided below the cooling barrel.
[0012] In a preferred embodiment, the output end of the drive motor is connected to the rotating blade.
[0013] The beneficial effects of adopting the above-mentioned further solution are: under the action of the drive motor, power is provided for the rotation of the rotating blade. When the drive motor drives the rotating blade to rotate, it will cause the liquid inside the cooling tank to generate eddies, which will cause the water level inside the cooling tank to rise. When the water level inside the cooling tank rises, the contact area with the air also increases, which will cool the liquid inside the cooling tank.
[0014] In a preferred embodiment, the mounting bracket has mounting holes arranged in a ring, and the included angle between two adjacent sets of mounting holes is equal.
[0015] The beneficial effect of adopting the above-mentioned further solution is that, with the help of the mounting holes, the mounting frame is fixed to the ground with bolts, which avoids the equipment tilting due to the shift of the center of gravity when the rotating blade drives the liquid to rotate.
[0016] In a preferred embodiment, the bottom of the water tank is provided with an arc-shaped through hole that communicates with the cooling tank. There are three arc-shaped through holes in total, and the three arc-shaped through holes are arranged in a ring, with the distance between two adjacent arc-shaped through holes being equal.
[0017] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the arc-shaped through hole, the water tank is connected to the mounting frame. When the rotating blade drives the water level in the cooling tank to rise, the cooled liquid enters the cooling tank through the arc-shaped through hole and mixes with the liquid in the cooling tank, thereby reducing the temperature of the liquid in the cooling tank.
[0018] In a preferred embodiment, the output of the first water pump is connected to the input end of the threaded cooling pipe, the output end of the threaded cooling pipe is connected to the cooling tank, the output end of the second water pump is connected to the cooling ring pipe frame, and the output end of the cooling ring pipe frame is connected to the water tank.
[0019] The beneficial effects of adopting the above-mentioned further solution are as follows: Under the action of the first water pump, the liquid in the water tank is pumped into the threaded cooling pipe to cool the cooling sleeve, thereby driving the heat on the extrusion die assembly. The threaded cooling pipe is further connected to the cooling barrel, so that the liquid re-enters the cooling barrel after passing through the threaded cooling pipe for recycling. Under the action of the second water pump, the liquid in the cooling barrel enters the cooling ring tube rack and flows back into the cooling barrel, realizing recycling.
[0020] In a preferred embodiment, the threaded cooling pipe is sleeved on the outside of the cooling ring tube frame, and the diameter of the threaded cooling pipe is larger than the diameter of the cooling ring tube frame.
[0021] The beneficial effects of adopting the above-mentioned further solution are as follows: Since the cooling ring tube frame is sleeved inside the threaded cooling tube, the heat absorbed is greater than that absorbed by the threaded cooling tube. At this time, the output end of the cooling ring tube frame is directly connected to the cooling tank, so that the liquid flowing back into the cooling tank can be directly mixed with the liquid after heat dissipation, and pumped back into the cooling ring tube frame for circulation under the action of the second water pump, thus avoiding poor heat dissipation effect caused by the liquid in the cooling ring tube frame not cooling down in time.
[0022] In a preferred embodiment, the top of both extrusion die cylinders is provided with a groove, and the bottom of both extrusion die cylinders is an arc-shaped structure.
[0023] The beneficial effects of adopting the above-mentioned further solution are: under the action of the groove, when the mold is demolded, the extrusion mold cylinder can be flipped to both sides by pulling the groove, so that the mold and the extrusion mold cylinder are separated. Furthermore, with the design of the arc structure at the bottom of the extrusion mold cylinder, the bottom of the extrusion mold cylinder is prevented from contacting the lifting seat when flipping, which would cause the mold to get stuck and unable to flip.
[0024] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0025] 1. In this utility model, the cooling sleeve is cooled by the action of the threaded cooling pipe and the cooling ring tube frame. The liquid in the threaded cooling pipe and the cooling ring tube frame is in a flowing state. Therefore, after the mold is injected, the extrusion mold assembly can be moved into the cooling sleeve by the hydraulic push rod. This allows the liquid in the threaded cooling pipe and the cooling ring tube frame to carry away the heat generated by the extrusion mold assembly during the flow process. Furthermore, the heat exchange effect is improved by the action of the cooling holes.
[0026] 2. In this utility model, since the cooling ring tube frame is sleeved inside the threaded cooling tube, the heat absorbed is greater than that absorbed by the threaded cooling tube. At this time, the output end of the cooling ring tube frame is directly connected to the cooling tank, so that the liquid flowing back into the cooling tank can be directly mixed with the liquid after heat dissipation, and pumped back into the cooling ring tube frame for circulation under the action of the second water pump, thus avoiding poor heat dissipation effect caused by the liquid in the cooling ring tube frame not cooling down in time.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0038] like Figure 1-5 As shown, this utility model provides a technical solution: an extrusion die with a high-efficiency heat dissipation structure, comprising:
[0039] The extrusion die assembly 2 consists of a lifting seat 21 and two extrusion die cylinders 22. The two extrusion die cylinders 22 are rotatably connected to the top of the lifting seat 21, and cooling holes 24 are provided on both extrusion die cylinders 22.
[0040] Cooling assembly 1 is composed of a cooling sleeve 11 sleeved on the outside of extrusion die assembly 2. The bottom of the cooling sleeve 11 is provided with a mounting base 13. The cooling sleeve 11 is fitted with a threaded cooling pipe 12 that passes through the mounting base 13 and a cooling ring tube bracket 14.
[0041] The water tank assembly 3 is composed of a water tank 31 located below the mounting base 13. A support rod 32 is provided between the water tank 31 and the mounting base 13. A hydraulic push rod 15 is provided on the top of the water tank 31, which passes through the mounting base 13 and is connected to the lifting base 21. A partition 35 is provided inside the water tank assembly 3. A first water pump 33 is fixedly connected to one side of the partition 35 inside the water tank 31, and a second water pump 34 is fixedly connected to the other side of the partition 35 inside the water tank 31.
[0042] The cooling component 4 consists of a cooling barrel 41 and a rotating blade 43. The rotating blade 43 is rotatably connected between the cooling barrel 41 and the water tank 31. A drive motor 44 and a mounting bracket 42 are installed below the cooling barrel 41. The output end of the drive motor 44 is connected to the rotating blade 43. Under the action of the threaded cooling pipe 12 and the cooling ring tube frame 14, the cooling sleeve 11 is cooled. The liquid in the threaded cooling pipe 12 and the cooling ring tube frame 14 is in a flowing state. Therefore, after the mold is injected, the hydraulic push rod 15 can drive the extrusion mold assembly 2 to move into the cooling sleeve 11, so that the liquid in the threaded cooling pipe 12 and the cooling ring tube frame 14 carries away the heat generated by the extrusion mold assembly 2 during the flow process. Furthermore, under the action of the cooling hole 24, the heat exchange effect is improved.
[0043] Furthermore, such as Figures 2-5As shown: The bottom of the water tank 31 has an arc-shaped through hole 36 that communicates with the cooling tank 41. There are three arc-shaped through holes 36 in total, and the three arc-shaped through holes 36 are arranged in a ring. The distance between two adjacent arc-shaped through holes 36 is equal. The output of the first water pump 33 is connected to the input end of the threaded cooling pipe 12, and the output end of the threaded cooling pipe 12 is connected to the cooling tank 41. The output end of the second water pump 34 is connected to the cooling ring tube frame 14, and the output end of the cooling ring tube frame 14 is connected to the water tank 31. The threaded cooling pipe 12 is sleeved on the outside of the cooling ring tube frame 14. The diameter of the threaded cooling pipe 12 is larger than the diameter of the cooling ring tube frame 14. Since the cooling ring tube frame 14 is fitted inside the threaded cooling pipe 12, the heat absorbed is greater than that absorbed by the threaded cooling pipe 12. At this time, the output end of the cooling ring tube frame 14 is directly connected to the cooling tank 41, so that the liquid flowing back into the cooling tank 41 can be directly mixed with the liquid after heat dissipation, and pumped back into the cooling ring tube frame 14 for circulation under the action of the second water pump 34, thus avoiding poor heat dissipation effect caused by the liquid in the cooling ring tube frame 14 not cooling down in time.
[0044] The above solutions also have the problem of displacement or tilting of the cooling component 4 during use, such as... Figure 5 As shown: The mounting frame 42 has mounting holes 421. The mounting holes 421 are arranged in a ring, and the included angle between two adjacent sets of mounting holes 421 is equal. Under the action of the mounting holes 421, the mounting frame 42 is fixed to the ground with bolts to prevent the equipment from tilting when the rotating blade 43 drives the liquid to rotate.
[0045] The above solution also has the problem of separation between the two extrusion die cylinders 22, such as... Figure 4 As shown: In this solution, the top of both extrusion die cylinders 22 are provided with grooves 23, and the bottom of both extrusion die cylinders 22 is an arc-shaped structure. Under the action of the grooves 23, when the die is demolded, the extrusion die cylinders 22 can be flipped to both sides by pulling the grooves 23, so that the die and the extrusion die cylinders 22 are separated. Furthermore, with the arc-shaped structure design at the bottom of the extrusion die cylinders 22, the bottom of the extrusion die cylinders 22 is prevented from contacting the lifting seat 21 when flipping the extrusion die cylinders 22, which would cause the cylinders to jam and be unable to flip.
[0046] Working principle:
[0047] like Figure 1-5As shown, firstly, the device is bolted to the designated position through the mounting hole 421. Secondly, clean water is injected into the cooling tank 41, and the top of the threaded cooling pipe 12 is connected to the cooling tank 41 through the connecting pipe. After fixing, the material is injected into the two extrusion mold cylinders 22 through the injection mold. At this time, under the action of the extrusion groove inside the extrusion mold cylinder 22, the material is extruded into the designated shape. After injection molding, the hydraulic push rod 15 is controlled to drive the extrusion mold assembly 2 to move downward, so that the extrusion mold assembly 2 is submerged in the cooling sleeve 11. At this time, under the action of the threaded cooling pipe 12 and the cooling ring pipe bracket 14, the heat generated by the extrusion mold assembly 2 is exchanged and cooled. After the extrusion mold assembly 2 has completely cooled down, the hydraulic push rod 15 drives the extrusion mold assembly 2 to move upward, and the extrusion mold cylinder 22 is flipped to both sides through the pull groove 23, so that the mold and the extrusion mold cylinder 22 are separated.
[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
