Description

Technical Field

[0001] The invention relates to the technical field of cold forging dies for heat dissipation substrates, in particular to a cold forging die for high-purity oxygen-free copper needle-type heat dissipation substrates. Background Art

[0002] High-purity oxygen-free copper needle-type heat dissipation substrates are widely used in many fields due to their excellent thermal conductivity and mechanical properties. They are used for heat dissipation of high-power electronic components to ensure stable operation of equipment in high-temperature environments. When die-casting the heat dissipation substrate, the appropriate cold forging die can be selected according to the design of the heat dissipation substrate.

[0003] However, when the existing mold is die-casting, the fixed particles in the air adhere to the impurities inside the mold during the die-casting process, which will cause metal debris, residues, etc. to be generated on the substrate during pressing. If there is no protective cover to block it, the metal debris and residues will splash everywhere. The splashed residues will generate high temperature on the surface during die-casting. When these splashed residues splash on the operator's body, they will not only cause abrasions, burns and other hazards to the operator's health, but also pollute the working environment.

[0004] In addition, after the die-casting of the existing substrate is completed, the substrate and the casting may stick together, resulting in the casting being unable to be removed smoothly. At this time, additional manpower is required to perform the removal operation. When the substrate is taken out, the die-casting table itself will produce plastic deformation during die-casting, and the internal atomic structure will change. At this time, the friction and slip between atoms will generate heat. When the operator removes the substrate, he may face the safety risk of burns due to the temperature on the die-casting table.

[0005] Therefore, a cold forging die for a high-purity oxygen-free copper needle-type heat dissipation substrate is proposed to solve the above problems. Summary of the invention

[0006] In view of this, the technical problem to be solved by the present invention is to propose a cold forging die for a high-purity oxygen-free copper needle-type heat dissipation substrate to solve the problem in the prior art that the equipment has no protective safety measures and the substrate die-casting molding is prone to sticking.

[0007] To achieve the above object, the present invention provides the following technical solutions: a cold forging die for a high-purity oxygen-free copper needle-type heat dissipation substrate, comprising an operating table, a die-casting table is fixedly connected to the operating table, a cold press is installed on the upper surface of the die-casting table, a control cabinet is installed on the side of the operating table close to the cold press, and also includes an ejection quick protection mechanism and a heat dissipation exhaust mechanism, the ejection quick protection mechanism is arranged on the lower surface of the die-casting table, and the heat dissipation exhaust mechanism is arranged in the middle of the die-casting table;

[0008] The ejection quick protection mechanism is used for protection during cold forging and die casting and for assisting the base plate to eject after die casting;

[0009] The heat dissipation and exhaust mechanism is used for cooling the interior of the die casting table.

[0010] Preferably, a die-casting groove is provided in the middle of the die-casting table, and a die-casting mold is installed on the cold press, and the die-casting mold is adapted to the size of the die-casting groove.

[0011] Preferably, the ejection quick protection mechanism includes a cold press plate, the outer side of the cold press plate is slidably connected in the die-casting groove, an auxiliary die-casting block is fixedly connected to the bottom of the cold press plate, a limit plate is arranged under the auxiliary die-casting block, and the limit plate is fixedly connected to the operating table.

[0012] Preferably, the ejection quick protection mechanism also includes a first connecting arm, one end of which is rotatably connected to the auxiliary die-casting block, the other end of which is rotatably connected to a seesaw, and the middle part of the seesaw is rotatably connected to the middle part of the die-casting table.

[0013] Preferably, the seesaw is rotatably connected to a second connecting arm at one end away from the first connecting arm, and the second connecting arm is rotatably connected to a protective plate at one end away from the seesaw. The outer surface of the protective plate is slidably connected to the die-casting table, and a return spring is fixedly connected to the bottom of the protective plate. The return spring is fixedly connected to the operating table at one end away from the protective plate.

[0014] Preferably, the heat dissipation and exhaust mechanism includes a pressing rod, one end of which is fixedly connected to the cold press, the other end of which is fixedly connected to a sealing sliding plate, and sealing cylinders are fixedly connected to both sides of the die-casting table.

[0015] Preferably, the sealing sliding disc is slidably connected to the inner wall of the sealing cylinder, and the bottom of the sealing cylinder is fixedly connected to an air pipe.

[0016] Preferably, one end of the air pipe away from the sealing cylinder is fixedly connected to a sealing chamber, and the sealing chamber is fixedly connected to the die-casting table. The die-casting table is evenly provided with heat dissipation holes, and the heat dissipation holes are connected to the heat dissipation holes.

[0017] Compared with the prior art, the cold forging die for a high-purity oxygen-free copper pin-type heat dissipation substrate provided by the present invention has the following beneficial effects:

[0018] 1. Through the setting of the ejection quick protection mechanism, when the cold press drives the mold to die-cast the substrate, the ejection quick protection mechanism will cause the protection plate to automatically rise. By raising the protection plate during die-casting, it can not only prevent external dust and debris from entering the casting area, but also reduce the risk of contamination of the casting. Compared with the prior art that directly die-casts the substrate, by setting the automatic lifting of the protection plate during die-casting, the protection plate is automatically retracted and released under the elastic action of the reset spring after the die-casting, which can not only prevent the impurities inside the mold caused by the fixed particles in the air in the die-casting process from being attached to the substrate, causing metal debris, residues, etc. to splash around during pressing, causing the risk of burns and cuts to personnel, but also facilitate the operation of the equipment, reduce the cumbersome operation process, and increase the safety and convenience of equipment use.

[0019] 2. Through the setting of the ejection quick protection mechanism, the die-cast substrate is automatically ejected from the die-casting tank after the die-casting is completed. This can not only reduce the physical labor of the operator when picking up the substrate from the die-casting tank again after the die-casting, but also reduce the stay time of the personnel at high temperature and reduce the labor intensity. It can also prevent the adhesion between the substrate and the casting, resulting in the inability to smoothly remove the casting, thereby reducing the operator's direct contact with the high temperature and high pressure environment for a long time when picking up the sticky substrate, reducing the risk of accidents and ensuring the safety of the operator.

[0020] At the same time, when the pressing of the substrate is completed, the protective plate can be automatically lowered, which not only makes it easier for the operator to take out the substrate after the pressing is completed, but also ensures that the protective plate can be accurately and timely lowered after each pressing is completed, avoiding improper operation or the operator forgetting to lower the protective plate after the pressing is completed, thereby avoiding potential safety risks and causing equipment damage or product quality problems. At the same time, the automatic lifting of the protective plate also facilitates the operation of the equipment, reduces cumbersome operating procedures and increases the safety and convenience of equipment use.

[0021] 3. Through the setting of heat dissipation and exhaust mechanism, because during the die-casting process, the equipment and the mold will generate a lot of heat. Through the heat dissipation and exhaust mechanism, the gas in the sealing cylinder can be compressed and blown into the heat dissipation holes during die-casting on the cold press. By making the gas in the sealing cylinder flow quickly, the air fluidity of the heat dissipation holes is enhanced, thereby improving the heat dissipation efficiency of the die-casting table during die-casting, helping the equipment to lower the temperature faster, which can not only effectively reduce the temperature of the equipment and prevent overheating, but also reduce the wear and aging of the equipment, extend the service life of the equipment, and reduce the maintenance and replacement costs.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0035] Example

[0036] Please refer to Figures 1 to 7 As shown:

[0037] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a cold forging die for a high-purity oxygen-free copper needle-type heat dissipation substrate, including an operating table 1, a die-casting table 13 is fixedly connected to the operating table 1, a cold press 11 is installed on the upper surface of the die-casting table 13, a control cabinet 12 is installed on the side of the operating table 1 close to the cold press 11, and also includes an ejection quick protection mechanism 2 and a heat dissipation exhaust mechanism 3, the ejection quick protection mechanism 2 is arranged on the lower surface of the die-casting table 13, and the heat dissipation exhaust mechanism 3 is arranged in the middle of the die-casting table 13;

[0038] The ejection quick protection mechanism 2 is used for protection during cold forging and die casting and for assisting the base plate to eject after die casting;

[0039] The heat dissipation and exhaust mechanism 3 is used to cool down the interior of the die casting table 13;

[0040] A die-casting groove is provided in the middle of the die-casting table 13, and a die-casting mold is installed on the cold press 11, and the die-casting mold is adapted to the size of the die-casting groove;

[0041] The ejection quick protection mechanism 2 includes a cold press plate 21, the outer side of the cold press plate 21 is slidably connected in the die-casting groove, the bottom of the cold press plate 21 is fixedly connected with an auxiliary die-casting block 22, a limit plate 28 is arranged below the auxiliary die-casting block 22, and the limit plate 28 is fixedly connected to the operating table 1;

[0042] The ejection quick protection mechanism 2 also includes a first connecting arm 23, one end of the first connecting arm 23 is rotatably connected to the auxiliary die-casting block 22, and the other end of the first connecting arm 23 is rotatably connected to a seesaw 24, and the middle part of the seesaw 24 is rotatably connected to the middle part of the die-casting table 13;

[0043] The end of the seesaw 24 away from the first connecting arm 23 is rotatably connected to the second connecting arm 25, and the end of the second connecting arm 25 away from the seesaw 24 is rotatably connected to the protective plate 26. The outer surface of the protective plate 26 is slidably connected to the die-casting table 13, and the bottom of the protective plate 26 is fixedly connected to a return spring 27. The end of the return spring 27 away from the protective plate 26 is fixedly connected to the operating table 1;

[0044] The first connecting arm 23 , the second connecting arm 25 and the return spring 27 are symmetrically arranged around the auxiliary die-casting block 22 , and the protection plate 26 slides symmetrically in the die-casting table 13 .

[0045] In the prior art, when the existing mold is die-casting, the fixed particles in the air adhere to the impurities inside the mold during the die-casting process, which will cause the substrate to produce metal debris, residues, etc. during pressing. If there is no protective cover to block it, it will splash everywhere, and the splashed residue will generate high temperature on the surface during die-casting. When these splashed residues splash on the operator's body, they will not only cause abrasions, burns and other hazards, but also have a certain impact on the operator's health, and will also pollute the working environment.

Compared with the prior art that directly die-casts the substrate, by arranging the protective plate 26 to be automatically raised during die-casting, and automatically retracting the protective plate 26 under the elastic action of the reset spring 27 after the die-casting is completed, it can not only prevent the fixed particles in the air from adhering to the impurities inside the mold during the die-casting process, which will cause the substrate to produce metal debris, residues, etc. to splash everywhere during pressing, causing burns and cuts to people, but also facilitate the operation of the equipment, reduce cumbersome operating procedures and increase the safety and convenience of equipment use.

[0046] For further examples, please refer to Figures 1 to 7 As shown:

[0047] The heat dissipation and exhaust mechanism 3 includes a pressing rod 31, one end of which is fixedly connected to the cold press 11, and the other end of which is fixedly connected to a sealing slide plate 33, and sealing cylinders 32 are fixedly connected to both sides of the die casting table 13;

[0048] The sealing sliding disc 33 is slidably connected to the inner wall of the sealing cylinder 32, and the bottom of the sealing cylinder 32 is fixedly connected to the air pipe 34;

[0049] The end of the air pipe 34 away from the sealing cylinder 32 is fixedly connected with a sealing chamber 35, and the sealing chamber 35 is fixedly connected to the die casting table 13. The die casting table 13 is evenly provided with heat dissipation holes 36, and the heat dissipation holes 36 are connected to the heat dissipation holes 36;

[0050] Wherein: the heat dissipation and exhaust mechanism 3 is symmetrically arranged on both sides of the die casting table 13 .

[0051] In the prior art, after the die-casting is completed, adhesion may occur between the substrate and the casting, resulting in the casting being unable to be smoothly removed. At this time, additional manpower is required for the removal operation. When the substrate is taken out, the die-casting table 13 itself will produce plastic deformation during die-casting. At this time, the internal atomic structure changes, and the friction and slip between atoms will generate heat. When the operator takes out the substrate, he may face the safety risk of scalding due to the temperature on the die-casting table 13. Compared with the prior art, through the implementation of this embodiment, because the equipment and the mold will generate a lot of heat during the die-casting process, the heat dissipation exhaust mechanism 3 can compress the gas in the sealing cylinder 32 and blow it into the heat dissipation hole 36 during the die-casting of the cold press 11. By making the gas in the sealing cylinder 32 flow quickly, the air flowability of the heat dissipation hole 36 is enhanced, thereby improving the heat dissipation efficiency of the die-casting table 13 during die-casting, helping the equipment to reduce the temperature faster, which can not only effectively reduce the temperature of the equipment and prevent overheating, but also reduce the wear and aging of the equipment, extend the service life of the equipment, and reduce maintenance and replacement costs.

[0052] Everything in the above example works like this:

[0053] In the initial state: the return spring 27 is not stretched and the cold press 11 is not started.

[0054] The following is the working process of the ejection quick protection mechanism 2 for protection during cold forging and die casting and for the ejection of the auxiliary substrate after die casting:

[0055] First, before the substrate needs to be die-cast, the operator manually puts the substrate blank to be die-cast into the die-casting groove opened on the die-casting table 13. After the substrate is placed in the die-casting groove, the operator starts to manually operate the start switch on the control cabinet 12. Because the cold press 11 is electrically connected to the control cabinet 12, the operator manually presses the start switch to start the cold press 11 and start the die-casting of the substrate in the die-casting groove of the die-casting table 13. At this time, because a mold is installed at the bottom of the cold press 11, the mold will be driven downward by the cold press 11 when it is die-casted downward. When the mold starts to die-cast to the surface of the substrate, at this time, Figure 4As shown, because the cold press plate 21 slides in the die-casting groove opened in the die-casting table 13, and the substrate is placed on the upper surface of the cold press plate 21, when the mold is driven by the cold press machine 11 to die-cast the substrate downward, the substrate drives the cold press plate 21 to start sliding downward in the die-casting groove, and because the auxiliary die-casting block 22 is fixed to the lower surface of the cold press plate 21, and the auxiliary die-casting block 22 is rotatably connected to the first connecting arm 23 on all sides, the downward movement of the cold press plate 21 will drive the auxiliary die-casting block 22 to move downward and cause the first connecting arm 23 to start moving downward. At this time, because the first connecting arm 23 is rotatably connected to the seesaw 24 and the middle of the seesaw 24 The first connecting arm 23 is rotated and connected to the die-casting table 13. At this time, 24 starts to rotate counterclockwise in the die-casting table 13 under the action of the first connecting arm 23 moving downward. At the same time, because the end of the seesaw 24 away from the first connecting arm 23 is rotatably connected to the protective plate 26 through the second connecting arm 25, when the seesaw 24 rotates counterclockwise, it will drive the second connecting arm 25 to drive the protective plate 26 to slide upward in the die-casting table 13. At the same time, because the bottom of the protective plate 26 is fixed to the reset spring 27, and the other end of the reset spring 27 is fixedly connected to the operating table 1, the reset spring 27 will begin to be stretched when the protective plate 26 slides upward;

[0056] At this time, when the cold press 11 drives the mold to die-cast the substrate, the protective plate 26 is raised to prevent the substrate from being damaged by impurities on the surface of the substrate during die-casting. At the same time, when the bottom of the auxiliary die-casting block 22 contacts the limit plate 28 through the die-casting of the cold press 11, the sensor device set on the limit plate 28 senses the cold press 11 to start moving upward. At this time, after the die-casting of the substrate is completed, the protective plate 26 starts to slide downward under the elastic action of the reset spring 27. At this time, the protective plate 26 drives the second connecting arm 25 to drive the rocker 24 The first connecting arm 23 is driven to drive the auxiliary die-casting block 22 to start sliding upwards through the clockwise rotation of the seesaw 24, and the upward sliding action of the auxiliary die-casting block 22 drives the cold press plate 21 to start sliding upwards along the die-casting groove. The substrate that has been pressed will be ejected by the upward action of the cold press plate 21. At this time, the operator only needs to take out the substrate directly. Through the setting of the ejection quick protection mechanism 2, when the cold press machine 11 drives the mold to die-cast the substrate, the protective plate 26 will be opened through the setting of the ejection quick protection mechanism 2. The protective plate 26 is automatically raised at the beginning, and the protective plate 26 is raised for protection during die-casting, which not only prevents external dust and debris from entering the casting area, but also reduces the risk of contamination of the casting. Compared with the prior art that directly performs die-casting on the substrate, by setting the protective plate 26 to be automatically raised during die-casting, and automatically retracting and releasing the protective plate 26 under the elastic action of the return spring 27 after the die-casting, it can not only prevent the impurities in the die-casting process caused by the fixed particles in the air adhering to the inside of the mold, which will cause metal debris, residues, etc. to splash around during the pressing of the substrate, causing burns and cuts to personnel, but also automatically lower the protective plate 26 when the pressing of the substrate is completed, which can not only facilitate the operator to take out the substrate after the pressing of the substrate is completed, but also ensure that the protective plate can be accurately and timely lowered after each pressing is completed, avoiding equipment damage or product quality problems caused by improper operation or the operator forgetting to lower the protective plate after the pressing is completed, thereby avoiding potential safety risks. At the same time, the automatic lifting of the protective plate 26 also facilitates the operation of the equipment, reduces cumbersome operating procedures, and increases the safety and convenience of equipment use.

[0057] Please refer to the above working process Figures 1 to 7 .

[0058] The following is the working process of the heat dissipation and exhaust mechanism 3 for cooling the inside of the die casting table 13:

[0059] During use, as the substrate undergoes plastic deformation during die casting, the internal atomic structure changes, and the friction and slip between atoms generate heat. Figure 6As shown, when the cold press 11 is die-casting the substrate, because the pressing rods 31 are evenly fixed on both sides of the cold press 11, and the lower part of the pressing rods 31 is fixed to each other, and the outer ring of the sealing sliding disk 33 slides inside the sealing cylinder 32 with good sealing performance, when the cold press 11 starts to die-cast the substrate, the pressing rods 31 are driven by the cold press 11 to start to move downward synchronously, and because the sealing sliding disk 33 slides on the inner wall of the sealing cylinder 32 with good sealing performance, the gas in the sealing cylinder 32 starts to be compressed when the sealing sliding disk 33 slides downward. At this time, because the bottom of the sealing cylinder 32 is connected to the air pipe 34, the gas in the sealing cylinder 32 will flow into the heat dissipation hole 36 through the sealing chamber 35 under the transmission of the air pipe 34;

[0060] At this time, when the cold press 11 starts die-casting, a certain amount of heat will be generated inside the die-casting table 13. At this time, the internal gas will be transported to the heat dissipation holes 36 through the sealing tube 32. Since the transported gas has a certain flow rate, an airflow is generated. At this time, the airflow with a certain flow rate will drive the gas in the heat dissipation holes 36 to flow. At this time, the heat generated in the heat dissipation holes 36 during the pressing of the die-casting table 13 is accumulated in the heat dissipation holes 36 through heat conduction. At this time, the gas is transported to the sealing chamber 35 through the air pipe 34 and passes into the heat dissipation holes 36 at a certain flow rate. At this time, the hot air in the heat dissipation holes 36 will be discharged out of the die-casting table 13 under a certain flow rate of airflow. Because the die-casting machine needs to continuously die-cast a large number of substrates during operation, the internal temperature of the die-casting table 13 can be quickly adjusted to an appropriate temperature through the heat dissipation exhaust mechanism 3. When the temperature is lowered, the mold temperature will be lowered by reducing the internal heat of the die-casting table 13, thereby preventing the mold from being in a high temperature state for a long time and accelerating the wear and aging of the mold, and further extending the service life of the mold. The heat dissipation exhaust mechanism 3 is set, because during the die-casting process, the equipment and the mold will generate a lot of heat. The heat dissipation exhaust mechanism 3 can be used to compress the gas in the sealing cylinder 32 and blow it into the heat dissipation hole 36 during die-casting on the cold press 11. The gas in the sealing cylinder 32 flows quickly, and the air fluidity of the heat dissipation hole 36 is enhanced, thereby improving the heat dissipation efficiency of the die-casting table 13 during die-casting, helping the equipment to lower the temperature faster, which can not only effectively reduce the temperature of the equipment and prevent overheating, but also reduce the wear and aging of the equipment, extend the service life of the equipment, and reduce maintenance and replacement costs.
