An exhaust cavity 504 is opened at one end of the inner wall of the mold sleeve 401, and one end of the exhaust pipe 505 is fixedly connected to one side of the exhaust cavity 504. The exhaust cavity 504 is connected through the exhaust pipe 505, and the vacuum pump 5 is used to discharge the air inside the mold sleeve 401. 06 realizes the exhaust of the air inside the mold sleeve 401; the exhaust method of the present application is that in the initial stage when the raw material 6 is pushed into the mold sleeve 401, the vacuum pump 506 is not started, and the air is compressed by the extrusion and pushing process to exhaust the air from the exhaust chamber 504. When the raw material 6 passes the middle of the mold sleeve 401 during the extrusion process, the vacuum pump 506 is started to extract the air inside the mold sleeve 401 to form a vacuum state, thereby avoiding the problem that the remaining air inside the mold sleeve 401 is difficult to exhaust after the raw material 6 passes the exhaust hole position.

[0034] See also Figure 3 An electric push rod 502 is arranged on the top of the exhaust cavity 504, and a closed plug rod 503 is fixedly connected to the output end of the electric push rod 502. The bottom of the exhaust cavity 504 is set to a pointed cone shape, so as to reduce the area of ​​the connecting surface between the exhaust cavity 504 and the inner cavity of the mold sleeve 401, thereby reducing the probability of the raw material 6 entering the exhaust cavity 504 during the extrusion process. The bottom of the closed plug rod 503 is also set to a pointed cone shape, so as to cooperate with the exhaust cavity 504 to achieve the closure of the exhaust cavity 504; the outer walls of the electric push rod 502 and the vacuum pump 506 are covered with a dust cover plate 501.

The size of the protrusion is consistent with the shape of the end of the inner cavity of the die sleeve 401, so as to achieve stable closure of the end of the die sleeve 401, and the supporting seat plate is used to support the raw material 6 during the extrusion forming process. By setting the pressure seat plate 402 to be threaded, it is more convenient to replace the pressure seat plate 402. The different protruding distances of the protrusions on different pressure seat plates 402 are used to control the length of the extruded pipeline.

A sealing gasket is fixedly installed on the inner wall of the through hole, and the inner diameter of the sealing gasket is consistent with the diameter of the mold core 203.

[0036] See also Figure 2 and Figure 4In order to realize automatic unloading of the heat dissipation tube after molding, the present application provides a unloading port at the bottom of the mold sleeve 401, and both sides of the inner wall of the unloading port are rotatably connected with supporting plates 403, and a plurality of adjusting cylinders 404 are arranged under the two supporting plates 403, and the plurality of adjusting cylinders 404 are slidably connected to the bottom of the supporting plates 403, and the width of the unloading port is greater than the width of the heat dissipation tube; a discharge port is provided on one side of the machine 1, and a discharge guide plate 405 arranged obliquely is fixedly connected to one side of the discharge port, and the height of the discharge guide plate 405 close to the discharge port is relatively low; the support plate 403 is flipped open by starting the adjusting cylinder 404 to realize the opening of the unloading port, so that after the mold core 203 is pulled out, the heat dissipation tube can fall to the discharge guide plate 405 under the action of its own gravity, and be discharged through the discharge port by rolling by itself.

[0037] See also Figure 2 In order to feed and push the raw material 6, the extrusion mechanism 3 includes a feeding box 301, and a feeding port is opened on the top of the feeding box 301. Before feeding, the aluminum alloy bar is heat treated and cut. The aluminum alloy ingot obtained by cutting is used as the raw material 6 for extrusion in this application. The width of the feeding port meets the needs of a single aluminum alloy ingot passing through.

[0038] To ensure the stability of the loading process, the present application has a material blocking rack 302 fixedly connected to the top of the loading port, and gaps are provided on both sides of the material blocking rack 302, that is, the end plate length of the material blocking rack 302 is greater than the side plate length on both sides, so as to facilitate the side lifting and loading operation of the aluminum alloy ingots.

[0039] See also Figure 2 and Figure 5 , a guide plate 303 is fixedly connected to the bottom of the feeding port, a receiving groove 309 is fixedly installed at the bottom of the inner wall of the feeding box 301, one end of the receiving groove 309 is arranged correspondingly to one end of the die sleeve 401, and the internal width of the receiving groove 309 is consistent with the width of the inner cavity of the die sleeve 401, and a push cylinder 307 is fixedly installed on one side of the feeding box 301, and a push seat 308 is fixedly connected to the output end of the push cylinder 307, and one end of the push seat 308 is slidably arranged inside the receiving groove 309, and the diameter of the push seat 308 is consistent with the inner cavity size of the die sleeve 401. The aluminum alloy ingot is guided and received by the guide plate 303 and the receiving groove 309 during the falling process. By corresponding the receiving groove 309 with the end of the die sleeve 401, the push of the push cylinder 307 to the push seat 308 is used to push the aluminum alloy ingot into the die sleeve 401, and cooperate with the die core 203 to realize the extrusion forming of the aluminum alloy;

[0040] In order to achieve full extrusion of the raw material 6, a recessed groove is opened on one side of the push seat 308, and one end of the mold core 203 is set to a shape matching the recessed groove, so that the push seat 308 and the end of the mold core 203 can be pushed into contact with each other to achieve complete extrusion of the material between the two, which facilitates the movement of the raw material 6 along the cavity between the mold core 203 and the mold sleeve 401, thereby forming a tubular shape.

[0041] In order to receive the raw material 6 and ensure the stable and controllable feeding speed and work flow, an adjusting motor 305 is fixedly installed in the middle of the feeding box 301, and a receiving plate 306 is fixedly connected to the output end of the adjusting motor 305. One side of the receiving plate 306 is set as an arc surface. The height of the receiving plate 306 satisfies that when its arc surface faces upward, the distance between it and the bottom of the guide plate 303 is less than the height of the aluminum alloy ingot. In this way, the contact between the receiving plate 306 and the aluminum alloy ingot is achieved by cooperating with the blocking setting of the guide plate 303, and the temporary storage of the aluminum alloy ingot is achieved. The posture of the receiving plate 306 is adjusted by the adjusting motor 305 to achieve the control of the unloading timing of the aluminum alloy ingot.

[0042] See also Figure 5 and 6 In order to facilitate the unloading operation of the aluminum alloy ingot, an oblique push block 310 is fixedly connected to the other side of the receiving plate 306. One side of the oblique push block 310 is set as an inclined surface. After the adjusting motor 305 drives the receiving plate 306 to rotate, the inclined surface formed by the oblique push block 310 is used to guide the aluminum alloy ingot, so that it moves toward the direction close to the mold sleeve 401 during the process of falling along the inclined surface, so that it falls stably; in this state, the distance between the bottom of the oblique push block 310 and the bottom of the guide plate is greater than the height of the aluminum alloy ingot, so that the aluminum alloy ingot can fall through easily;

[0043] In specific implementation, the connection position between the adjustment motor 305 and the receiving plate 306 can be set eccentrically, that is, the connection position between the output end of the adjustment motor 305 and the receiving plate 306 is close to the position of the inclined push block 310, so that when the inclined push block 310 is rotated upward, the distance between the inclined push block 310 and the material guide frame can be increased as much as possible, thereby facilitating the discharge of the aluminum alloy ingots.

[0044] In order to detect the temperature of the aluminum alloy ingot, a temperature sensor 304 is fixedly installed on the inner wall of the guide plate 303 to detect the temperature of the aluminum alloy ingot before extrusion to avoid the extrusion process of the aluminum alloy ingot with insufficient temperature, which will lead to the production of defective products.

[0045] See also Figure 6 and Figure 7In order to discharge the unqualified products detected in time, a discharge port 314 is provided on the top of one side of the loading box 301, and a discharge diverter plate 312 is rotatably connected to one side of the guide plate 303. A discharge push rod 311 is provided on one side of the guide plate 303, and an adapter 313 is fixedly connected to the output end of the discharge push rod 311. A connecting rod is rotatably connected to one side of the adapter 313, and a rotating shaft is rotatably connected to one end of the connecting rod. A slide groove is provided on one side of the discharge diverter plate 312, and the rotating shaft is slidably connected to the inner wall of the slide groove. Through the arrangement of the discharge diverter plate 312 and other structures, when the aluminum alloy ingot needs to be discharged, it is flipped open, and the action of the receiving plate 306 driven by the adjusting motor 305 to rotate is coordinated to discharge the aluminum alloy ingot from the discharge port 314.

[0046] See also Figure 8 The traction mechanism 2 includes a cover plate 201, a traction cylinder 202 is fixedly installed on one side of the inner wall of the cover plate 201, and the outer wall of the traction cylinder 202 is fixedly connected to the cover plate 201 by a plurality of support frames 204, so as to improve the structural strength of the cover plate 201 and the installation stability of the traction cylinder 202. The output end of the traction cylinder 202 is fixedly connected with a mold core 203, and the mold core 203 is driven to move by the traction cylinder 202 to realize the extraction operation of the mold core 203, so as to facilitate the automatic unloading operation of the heat dissipation pipe obtained by forming;

[0047] A limiting sleeve 205 is fixedly installed on the other side of the inner wall of the cover plate 201, and a limiting cavity is opened in the middle of the limiting sleeve 205. A plurality of supporting rollers 206 are rotatably installed inside the limiting cavity. The plurality of supporting rollers 206 are used to limit the output end of the traction cylinder 202 and to assist in supporting the output end of the traction cylinder 202, thereby avoiding the problem of self-bending caused by the heavy weight of the mold core 203 and the long length of the output end, and improving the movement stability of the output end of the traction cylinder 202 and the mold core 203.

[0048] When the present invention is used, firstly, the aluminum alloy bar material is heat treated and cut by an external heat treatment furnace and a cutting device. The aluminum alloy ingot obtained by cutting, which is a rod cut and has a basic shape of a cylindrical metal segment, is used as the raw material 6 for extrusion in this application. The aluminum alloy ingot is lifted by an external lifting device to pass through the notch of the loading rack to the top of the loading port. The width of the loading port meets the needs of a single aluminum alloy ingot passing through. In this way, after the lifting device is released, the aluminum alloy ingot passes through the loading port and falls into the guide plate 303, and is received by the receiving plate 306. At this time, the temperature of the aluminum alloy ingot is detected by the temperature sensor 304. When the temperature of the aluminum alloy ingot does not meet the requirements of the extrusion processing, the electric push rod 502 drives the adapter 313 to rise, and then drives the unloading diverter plate 312 to flip open. At the same time, the adjusting motor 305 drives the receiving plate 306 to rotate toward the discharge port 314, and the aluminum alloy ingot is discharged from the discharge port 314. For the specific process, please refer to Figure 7 (a)-(b); When the temperature of the aluminum alloy ingot meets the extrusion processing requirements, the adjusting motor 305 drives the receiving plate 306 to flip so that the inclined push block 310 is upward, and the aluminum alloy ingot moves along the inclined surface under its own gravity and falls into the receiving groove 309; For the specific process, please refer to Figure 5 (a)-(c);

[0049] Then, the push cylinder 307 starts to push out, driving the push seat 308 to move, pushing the aluminum alloy ingot in the receiving groove 309 into the die sleeve 401. When the aluminum alloy ingot contacts the die core 203, it gradually deforms and moves into the tubular cavity between the die core 203 and the die sleeve 401. The air is compressed by the extrusion and pushing process, and the air is discharged from the exhaust cavity 504. When the raw material 6 passes the middle of the die sleeve 401 during the extrusion process, the vacuum pump 506 is started to extract the air inside the die sleeve 401 through the exhaust pipe 505 and the exhaust cavity 504 to form a vacuum state. When the push seat 308 contacts the end of the die core 203 stably, it is judged that the extrusion operation is completed.

[0050] At this time, the traction cylinder 202 drives the mold core 203 to be retracted. After the withdrawal is completed, the adjusting cylinder 404 drives the supporting plate 403 to flip, so that the formed heat dissipation tube is discharged through the unloading port, and then received by the discharge guide plate 405 and discharged from the discharge port; then the push cylinder 307 drives the push seat 308 to reset, and the next lifting operation of the aluminum alloy ingot is carried out by the external lifting equipment.
