Description

Technical Field

[0001] The present invention relates to the technical field of tooth radiator molds, and more specifically, to a high-fold tooth radiator mold. Background Art

[0002] In the field of modern electronic device manufacturing, with the continuous improvement of chip performance, the heat generated during its operation is also increasing day by day. To ensure the stable operation of electronic devices, high-fold tooth radiators, as efficient heat dissipation components, have a continuously growing demand in the market. The production of high-fold tooth radiators highly depends on mold manufacturing technology, and the mold cooling link is crucial.

[0003] Currently, mold cooling faces many intractable problems. Especially, the problem of impurities adhering to the inner wall of the cooling tank seriously affects the cooling effect. During the production of high-fold tooth radiators, the mold needs to repeatedly contact high-temperature aluminum alloy melt. When the aluminum alloy melt is injected into the mold cavity, part of the melt will remain on the inner wall of the cooling tank. As the number of production increases, these residual melts gradually accumulate and solidify, forming a stubborn impurity layer.

[0004] At the same time, during the recycling process of the coolant, some tiny particulate impurities will also be carried. These particles may come from the precipitation of additives in the coolant itself or the debris generated by the wear of pipes in the circulation system. Due to the complex internal structure of the cooling tank, some impurities are likely to deposit at the corners, gaps, and other parts of the cooling tank.

[0005] The adhesion of impurities forms a heat insulation layer on the inner wall of the cooling tank, greatly reducing the heat conduction efficiency of the cooling tank. This makes the coolant unable to effectively absorb the heat of the mold, hindering the heat exchange between the coolant and the mold wall. The direct consequence is that the cooling effect is greatly reduced, the cooling speed of the aluminum alloy melt becomes slower and the cooling is uneven, resulting in internal structural defects in the radiator product, such as coarse grains and loose tissues, seriously affecting the heat dissipation performance and mechanical strength of the radiator. Therefore, we have designed a high-fold tooth radiator mold. Summary of the Invention

[0006] The present invention provides a high-fold tooth radiator mold to solve the technical problem in the related art that currently, impurities are easily attached to the inner wall of the mold cooling tank, and the sources include the residue of aluminum alloy melt and particles in the coolant. The adhesion of impurities reduces the heat conduction efficiency, hinders the heat exchange, affects the cooling effect, and causes defects in the product.

[0007] The present invention provides a high-ratio tooth radiator mold, including an upper mold, a lower mold located below the upper mold and having a tapered groove and a mounting groove formed inside; a scraping mechanism slidably installed inside the tapered groove, which can accelerate the movement of the scraping mechanism in cooperation with the tapered groove; a pulling mechanism installed inside the mounting groove and driving the scraping mechanism to operate during the working process of the upper mold and the lower mold; and a supply mechanism installed on the left and right sides of the lower mold to supply liquid to the tapered groove in a cycle.

[0008] As a further optimized solution of the present invention, the pulling mechanism includes a driving column with a driving groove formed on its surface; a rotating shaft fixedly installed on the driving column and rotatably connected to the lower mold; a driving member, one end of which is slidably connected to the lower mold and the other end is located inside the rotating groove for driving the driving column to rotate; a pressing rod fixedly installed on the driving member and slidably connected to the lower mold; and a third spring fixedly installed at the bottom end of the driving member and fixedly connected to the lower mold.

[0009] As a further optimized solution of the present invention, the pulling mechanism further includes a crown gear fixedly installed on the rotating shaft; a first gear meshing with the crown gear; a reciprocating lead screw fixedly installed on the gear and fixedly connected to the lower mold; and a threaded plate slidably installed inside the mounting groove and threadedly connected to the reciprocating lead screw.

[0010] As a further optimized solution of the present invention, the pulling mechanism further includes a sliding tube fixedly installed on the lower mold; a second pulling rope passing through the sliding tube, and both ends thereof are fixedly connected to both sides of the threaded block respectively.

[0011] As a further optimized solution of the present invention, the scraping mechanism includes a connecting disk fixedly connected to the second pulling rope; a flow disturbing component, one end of which is fixedly installed on the connecting disk and the other end is fixedly connected with a rubber ring.

[0012] As a further optimized solution of the present invention, the flow disturbing component includes a fixed box fixedly connected to the connecting disk; an extension plate slidably installed on the fixed box and connected to the fixed box through a second spring.

[0013] As a further optimized solution of the present invention, the supply mechanism includes a mounting box; a connecting pipe, one end of which is fixedly connected to the mold and the other end is fixedly connected to the mounting box, so that the tapered groove is communicated with the mounting box; and a liquid inlet pipe fixedly installed on the mounting box.

[0014] As a further optimized solution of the present invention, the supply mechanism further includes a scraping plate slidably connected to the mounting box, the scraping plate is connected to the mounting box through a first spring; a filter plate fixedly installed inside the connecting pipe and cleaned by the scraping plate; and a first pulling rope, one end of which is fixedly connected to the scraping plate and the other end is fixedly connected to the upper mold.

[0015] As a further optimized solution of the present invention, the inlet cross-section of the conical groove flow channel is large and gradually narrows at the end.

[0016] As a further optimized solution of the present invention, the rubber ring can be compressed and can be in close contact with the inner wall of the conical groove under the action of the second spring.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. For the high-ratio tooth radiator mold of the present invention, through the conical groove, the inlet cross-section of its flow channel is large, which can slow down the flow rate of the coolant, and the end gradually narrows, which can accelerate the flow of the coolant. This unique design can effectively improve the cooling effect of the coolant on the lower mold, accelerate the cooling and solidification of the aluminum alloy melt, and improve the production quality of the radiator.

[0019] 2. For the high-ratio tooth radiator mold of the present invention, through the coordinated cooperation of the pulling mechanism and the scraping mechanism, when the upper mold presses down, it can drive the scraping mechanism to continuously move in the conical groove. The rubber ring on the scraping mechanism is always in close contact with the inner wall of the conical groove under the action of the second spring, and can clean the impurities attached to the inner wall of the conical groove, avoiding the influence of impurities on the mold heat dissipation and product quality.

[0020] 3. For the high-ratio tooth radiator mold of the present invention, through the spoiler assembly in the scraping mechanism which is inclined and movable, it can change the flowing path of the water flow, fluctuate the water flow, and enhance the heat dissipation effect. Even if the rubber ring wears due to long-term work, it can still closely adhere to the inner wall of the conical groove under the action of the second spring, ensuring good heat dissipation performance.

[0021] 4. For the high-ratio tooth radiator mold of the present invention, through the filter plate in the supply mechanism, it can filter the impurities in the coolant and prevent the impurities from entering the circulation device. At the same time, the up and down movement of the upper mold controls the scraper to clean the filter plate through the first pull rope, avoiding the blockage of the filter plate, ensuring the normal operation of the coolant circulation system, and improving the production efficiency.

Detailed implementation manners

[0032] Now, the subject matter described herein will be discussed with reference to example embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the protection scope of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described in some examples can also be combined in other examples.

[0033] As Figures 1 to 9 shown, a high - magnification tooth radiator mold according to an embodiment of the present invention mainly consists of an upper mold 1, a lower mold 2, a scraping mechanism, a pulling mechanism, and a supply mechanism. Each component cooperates with each other and works together to jointly ensure the efficient and high - quality production of the high - magnification tooth radiator.

[0034] The lower mold 2 is located directly below the upper mold 1. It is the basic support component of the entire mold, providing a stable space for the shaping of the aluminum alloy melt. Inside it, a conical groove 405 and a mounting groove 415 are carefully designed.

[0035] The conical groove 405 is a key channel for the coolant circulation, and its unique flow channel design plays a crucial role in the cooling effect.

[0036] The runner inlet is deliberately designed with a relatively large cross-section. When the coolant flows in, the large cross-section can effectively slow down the flow rate of the coolant, allowing sufficient time for the coolant to fully exchange heat with the lower mold 2, ensuring that heat can be efficiently transferred from the mold to the coolant.

[0037] The end of the runner gradually narrows. This variable-diameter design can accelerate the flow rate of the coolant during the flow process, enhance the scouring effect of the coolant, further improve the cooling efficiency, and at the same time provide a favorable hydrodynamic environment for the movement of the scraping mechanism. The installation groove 415 provides an installation space and a movement track for the pulling mechanism, ensuring that the pulling mechanism can operate stably and accurately.

[0038] The scraping mechanism is slidably installed inside the conical groove 405 and is adapted to the unique structure of the conical groove 405, enabling it to accelerate during the movement process by means of the conical groove 405.

[0039] The core component of the scraping mechanism, the connection disk 504, is firmly fixed to the second pull rope 402 to ensure that it will not fall off or become loose during the pulling process. The connection disk 504 plays a role in connection and support. It tightly combines various components together to form a whole. A flow disturbance component is installed on the connection disk 504, and one end of the flow disturbance component is connected to a rubber ring 501 with special elasticity.

[0040] The flow disturbance component consists of a fixed box 503 and an extension plate 502 slidably installed on the fixed box 503. The extension plate 502 is elastically connected to the fixed box 503 by a second spring 505. When the water flow passes through the flow disturbance component, since the flow disturbance component is inclinedly installed on the connection disk 504 and will move to a certain extent under the impact force of the water flow, this changes the flowing path of the water flow and forms fluctuations.

[0041] These fluctuations can effectively increase the contact area between the coolant and the mold wall, improve the heat exchange efficiency, and thus better achieve the heat dissipation purpose. The rubber ring 501 has good compressibility and can adaptively adjust according to the dimensions of different parts of the conical groove 405. Under the elastic force of the second spring 505, it always remains in close contact with the inner wall of the conical groove 405. In this way, during the movement of the scraping mechanism, the rubber ring 501 can effectively clean the impurities on the inner wall of the conical groove 405, preventing the accumulation of impurities from affecting the flow of the coolant and the heat transfer efficiency. Even after long-term use, when the rubber ring 501 wears and its thickness changes, the second spring 505 can still ensure that the rubber ring 501 tightly adheres to the inside of the conical groove 405 through its own elastic deformation, maintaining a good cleaning effect. At the same time, it is also beneficial for the coolant to achieve heat and cold neutralization in the conical groove 405, further enhancing the uniformity and stability of cooling.

[0042] The pulling mechanism is firmly installed inside the installation groove 415 and plays a key role in driving the scraping mechanism during the operation of the mold, that is, when the upper mold 1 interacts with the lower mold 2. The pulling mechanism includes a driving column 410 with a driving groove on its surface, a rotating shaft 407 fixedly installed on the driving column 410 and rotatably connected to the lower mold 2, a driving member 409 with one end slidably connected to the lower mold 2 and one end located inside the rotating groove for driving the driving column 410 to rotate, a pressing rod 401 fixedly installed on the driving member 409 and slidably connected to the lower mold 2, and a third spring 413 fixedly installed at the bottom of the driving member 409 and fixedly connected to the lower mold 2. When the upper mold 1 presses down, its bottom will precisely squeeze the pressing rod 401, causing the pressing rod 401 to move downward along a specific guiding structure. The downward movement of the pressing rod 401 drives the driving member 409 fixedly connected thereto to move downward synchronously. During the movement of the driving member 409, under the guiding action of the track groove 411, the driving column 410 starts to rotate around the axis.

[0043] The rotating shaft 407 plays a role in transmitting power, transmitting the rotation of the driving column 410 to subsequent components.

[0044] The third spring 413 provides a restoring elastic force after the driving member 409 moves downward, ensuring that the pulling mechanism can work cyclically. The pulling mechanism also includes a crown gear 408 fixedly installed on the rotating shaft 407, a first gear 412 meshing with the crown gear 408, a reciprocating lead screw 403 fixedly installed on the first gear 412 and fixedly connected to the lower mold 2, and a threaded plate 404 slidably installed inside the installation groove 415 and threadedly connected to the reciprocating lead screw 403. The rotation of the driving column 410 drives the rotating shaft 407 and the crown gear 408 to rotate in sequence.

[0045] The rotation of the crown gear 408 drives the closely meshing first gear 412 to start rotating, and the rotation of the first gear 412 finally causes the reciprocating lead screw 403 fixed on it to rotate. When the reciprocating lead screw 403 rotates, the threaded plate 404 threadedly connected to it will perform a reciprocating linear motion along the axial direction of the lead screw inside the installation groove 415.

[0046] The threaded plate 404 is connected to the scraping mechanism through a second pull rope 402. Therefore, the reciprocating movement of the threaded plate 404 can drive the scraping mechanism to continuously move back and forth in the conical groove 405, thereby realizing a comprehensive and efficient cleaning of the inner wall of the conical groove 405, avoiding impurities adhering to the wall of the conical groove 405, and ensuring that the cooling effect is not affected.

[0047] The supply mechanism is symmetrically installed on the left and right sides of the lower mold 2 and shoulders the important mission of circulatingly supplying coolant to the conical groove 405.

[0048] The supply mechanism includes an installation box 301, a connecting pipe 303 with one end fixedly connected to the lower mold 2 and the other end fixedly connected to the installation box 301 so that the conical groove 405 communicates with the installation box 301, and a liquid inlet pipe 306 fixedly installed on the installation box 301.

[0049] The installation box 301 functions to store and buffer the coolant, ensuring that the coolant can flow in and out stably.

[0050] The connecting pipe 303 is the channel for the coolant circulation. It connects the installation box 301 and the conical groove 405 to form a complete circulation loop.

[0051] The liquid inlet pipe 306 is closely connected to an efficient external circulation device, providing a stable inlet for the input of the coolant and ensuring the continuous and sufficient supply of the coolant.

[0052] The supply mechanism further includes a scraping plate 304 slidably connected to the installation box 301 and connected to the installation box 301 through a first spring 305, a filter plate 307 fixedly installed inside the connecting pipe 303 and cleaned by the scraping plate 304, and a first pull rope 302 with one end fixedly connected to the scraping plate 304 and the other end fixedly connected to the upper mold 1.

[0053] The filter plate 307 installed inside the connecting pipe 303 functions to filter the impurities carried by the coolant during the circulation process, preventing these impurities from entering the circulation device and affecting the normal operation of the entire system.

[0054] The scraping plate 304 provided in the installation box 301 is connected to the installation box 301 through a first spring 305 and fixedly connected to the upper mold 1 through a first pull rope 302. During the process of the scraping mechanism cleaning the conical groove 405, inevitably, impurities will be cleaned out and flow into the circulation device along with the coolant, and finally enter the connecting pipe 303.

[0055] At this time, the filter plate 307 can effectively block these impurities. And every time the upper mold 1 moves up and down, it will drive the scraping plate 304 to slide inside the installation box 301 through the first pull rope 302. During the sliding process of the scraping plate 304, it will clean the filter plate 307, timely remove the impurities attached to the filter plate 307, avoid the blockage of the filter plate 307, ensure that the coolant circulation system always remains unobstructed, and thus ensure the continuous and stable progress of the mold cooling process. When using this mold to produce high - magnification tooth radiators, the operation process has a rigorous sequence.

[0056] First, the upper mold 1 slowly moves downward along the established track until it comes into close contact with the lower mold 2. At this time, the molten aluminum alloy liquid in a molten state is accurately pressed into the mold cavity at a high speed and high pressure to ensure that the aluminum alloy liquid can uniformly and fully fill the cavity, laying the foundation for subsequent forming. After the upper mold 1 and the lower mold 2 complete the contact, the supply mechanism is quickly activated.

[0057] Its liquid inlet pipe 306 is closely connected to an efficient external circulation device. Under the action of a strong pressure difference, the coolant continuously pours into the conical groove 405 through the connecting pipe 303.

[0058] When the coolant flows in the conical groove 405, relying on its own low-temperature characteristics, it quickly absorbs the heat of the lower mold 2, thereby cooling the aluminum alloy melt, making it gradually cool and solidify, and finally forming the required high multiple-tooth radiator product.

[0059] In this process, the quality of the cooling effect directly affects the quality of the product, and the efficient circulation supply of the coolant is crucial.

[0060] Through the coordinated work of each component, this mold can effectively improve the cooling efficiency, ensure the product quality, extend the service life of the mold, and achieve the efficient production of high multiple-tooth radiators.

[0061] Working principle: When using this mold to produce a high multiple-tooth radiator, first the upper mold 1 moves down to contact the lower mold 2. At this time, the molten aluminum alloy liquid is pressed into the mold cavity at a high speed. After the upper mold 1 and the lower mold 2 come into contact, the supply mechanism starts to work. The liquid inlet pipe 306 is connected to the external circulation device, and the coolant enters the conical groove 405 through the connecting pipe 303 to cool the lower mold 2 and cool the aluminum alloy melt to solidify it.

[0062] When the upper mold 1 moves down, it will squeeze the push rod 401 in the pulling mechanism. The downward movement of the push rod 401 drives the driving part 409 to move down. During the downward movement of the driving part 409, due to the action of the track groove 411, the driving column 410 rotates. The rotation of the driving column 410 drives the rotating shaft 407 to rotate, and further makes the crown gear 408 rotate. The crown gear 408 drives the first gear 412 meshing with it to rotate. The rotation of the first gear 412 makes the reciprocating lead screw 403 rotate. The reciprocating lead screw 403 drives the threaded plate 404 to reciprocate in the installation groove 415. The threaded plate 404 pulls the scraping mechanism to continuously move in the conical groove 405 through the second pull rope 402 to clean the inner wall of the conical groove 405.

[0063] When the water flow passes through the flow disturbing component in the scraping mechanism, because it is inclined and movable, it will change the water flow path and fluctuate the water flow to enhance the heat dissipation effect. Under the action of the second spring 505, the rubber ring 501 can closely fit the inner wall of the conical groove 405, which can not only clean impurities but also adapt to grooves of different sizes.

[0064] During the coolant circulation process, the impurities cleaned out by the scraping mechanism will flow into the connecting pipe 303, and the filter plate 307 can filter these impurities; each time the upper mold 1 moves up and down, the scraper 304 is pulled by the first pulling rope 302 to clean the filter plate 307, preventing the filter plate 307 from being blocked, ensuring smooth coolant circulation, and realizing the continuous and stable operation of the mold.

[0065] The embodiments of the present invention have been described above, but the present embodiments are not limited to the above specific embodiments. The above specific embodiments are merely illustrative rather than restrictive. Under the inspiration of the present embodiments, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of the present embodiments.
