Technical Field

[0001] The invention relates to the technical field of refrigerator heat dissipation pipe processing, in particular to a hot extrusion die for processing an aluminum alloy heat dissipation pipe for a refrigerator. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature. There are compressors and ice makers in the cabinet or box for ice making. The refrigerator will generate a lot of heat during use, so a heat pipe is needed to dissipate the heat of the refrigerator. In the process of processing aluminum alloy heat pipes, a hot extruder mold is needed to extrude the heated aluminum alloy ingredients.

[0003] For example, the patent with publication number CN216801144U discloses a hot extrusion die for processing aluminum alloy heat dissipation pipes. This patent can increase the sealing of the connection between the connection block and the connection cylinder through a sealing gasket to prevent the material from being squeezed out during the production process. Through the connection between the limit rod and the slot, the limit rod can limit the cover plate through the slot, and the limit on the cover plate can be released by sliding the limit rod, which is convenient for disassembly of the cover plate and replacement and maintenance of the mold. However, in the actual use of this type of device, there is a problem that the heat dissipation pipe blank needs to be manually added to the cavity of the mold before loading, which increases the amount of manual operation.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a hot extrusion die for processing aluminum alloy heat dissipation pipes for refrigerators is proposed. Summary of the invention

[0011] Furthermore, a heating component is arranged inside the outer end of the other side of the rotating seat, and the heating component includes an inner lining tube, a heating coil and a connecting terminal. The inner lining tube is placed inside the other end of the rotating seat, and a heating coil is arranged on the outer side of the inner lining tube.

[0012] Furthermore, the heating component also includes a connecting seat, an elastic contact piece and a power cord.

[0016] The present invention provides a hot extrusion die for processing an aluminum alloy heat dissipation pipe for a refrigerator, which has the following beneficial effects:

[0017] 1. The present invention first places a plurality of rod-shaped heat dissipation tube blanks in a material guide frame. At this time, since the width of the material guide frame is equal to the length of the rod-shaped blanks, the blanks can be neatly arranged inside the material guide frame, and the rod-shaped blanks at the end of the material guide frame can fall to the lower end of the limit frame. At this time, when the motor drives the screw to rotate, the transmission rod will limit the rotation of the driving plate, so the horizontal position of the driving plate can be controlled, and when the driving plate drives the ejector rod and the movable mold to hot extrude the heated blanks, the driving plate will also drive The feeding rod moves toward the limit frame, so that the push plate moves the blank inside the limit frame to the cavity at the other end of the rotating seat. Therefore, there is no need to add an additional power source to automatically load the materials, which makes the operation more labor-saving. When the driving plate moves back and resets, the push plate can be moved out of the limit frame again, and the rod-shaped blank above can be automatically filled into the limit frame under the action of gravity. At the same time, the material guide frame is inclined, so that the rod-shaped blank can automatically move toward the limit frame under the action of gravity, thereby facilitating the loading operation of the blanks one by one.

[0018] When the driving plate drives the push rod to move out of the rotating seat, the driving plate continues to move, and the sliding column on the transmission rod can be driven to slide into the guide groove inside the driving sleeve. Since the driving sleeve is rotatably connected to the rotating seat, when the sliding column slides in the guide groove, the driving sleeve can be driven to rotate. At this time, the compression spring will push the card plate to make it close to the ratchet ring, so that the ratchet ring can be driven to rotate synchronously through the card plate, and the rotating seat can be rotated a quarter of a circle, so that the blank after loading can be rotated to the bottom for heating treatment, and the blank after heating treatment at the bottom can be moved to the movable mold for extrusion molding treatment, and when the driving plate drives the push rod to extrude the blank, the driving sleeve will rotate in the opposite direction. At this time, since the one-way bearing will prevent the rotating seat from rotating in the opposite direction, the card plate will squeeze the compression spring and slide with the ratchet ring. Therefore, the rotating seat will not be driven to rotate during the extrusion process, so that during the reciprocating extrusion process, the position of the rotating seat can be automatically controlled to feed the material, which is beneficial to improve the overall automation level.

[0019] 3. In the present invention, during extrusion molding, the lower connecting terminal will contact the elastic contact piece, so that the external power supply can make the heating coil work normally through the power line, the elastic contact piece and the connecting terminal, and the eddy current effect generated by it is used to heat the blank. Therefore, the blank to be processed is heated while the blank is extruded, thereby saving time and improving processing efficiency. When the rotating seat rotates, it will drive the connecting terminal to move together, so that it is separated from the elastic contact piece, thereby stopping heating, and the blank after loading will also move to the bottom. At this time, the connecting terminal here will contact the elastic contact piece again, so that the working state of the heating coil can be automatically controlled without manual switching, saving time and effort, and a fixed cover made of insulating material can be used to shield and protect the outside, thereby improving safety performance during use.

[0020] 4. During the rotation of the rotating seat, the present invention will also drive the baffle rod to move together. At this time, the reset spring will push the pulley seat at the upper end under the limit of the rotating seat, so that it can fit tightly with the fixed ring or the limit strip. Therefore, the limit strip can be used to change the position of the baffle rod, so that during the feeding and heating of the blank, one end of the blank can be limited to prevent it from moving out of the heating range of the heating component. At the same time, the baffle plate can also be used to limit and cover the other end of the blank to prevent the blank from falling during the rotation of the rotating seat. When the heated blank is hot-extruded, since the limit strip will not block the pulley seat, the baffle rod can be separated from the end of the blank so that the push rod can push the blank to the fixed mold for extrusion molding.

A feeding assembly 14 is arranged at the center of the rotating seat 4. The feeding assembly 14 includes a transmission rod 1401 and a slide column 1402. A transmission rod 1401 is fixed to the middle part of one side of the driving plate 8, and a slide column 1402 is connected to the outer side of the end of the transmission rod 1401. The feeding assembly 14 also includes a driving sleeve 1403 and a guide groove 1404. A driving sleeve 1403 is sleeved on the outer side of one end of the transmission rod 1401, and the driving sleeve 1403 is rotatably connected to the rotating seat 4. A guide groove 1404 is provided inside the driving sleeve 1403, and the guide groove 1404 is Z-shaped. The feeding assembly 14 also includes a clamping plate 1405, a compression spring 1406 and a ratchet ring 1407. The clamping plate 1405 is rotatably connected to one side of the driving sleeve 1403, and the compression spring 1406 is connected to one side of the clamping plate 1405, and the compression spring 1406 is fixedly connected to the driving sleeve 1403. A ratchet ring 1407 is connected to one end of the clamping plate 1405, and the ratchet ring 1407 is fixedly connected to the rotating seat 4.

[0032] The specific operation is as follows: a plurality of rod-shaped heat dissipation tube blanks are placed in the material guide frame 1304, and the rod-shaped blanks at the end of the material guide frame 1304 will fall into the lower end of the limit frame 1305. When the motor 6 drives the screw 7 to rotate, since the transmission rod 1401 will limit the rotation of the drive plate 8, the position of the drive plate 8 can be controlled. When the drive plate 8 moves toward the motor 6, the sliding column 1402 on the transmission rod 1401 will be driven to slide into the guide groove 1404 inside the drive sleeve 1403. Since the drive sleeve 1403 is rotatably connected to the rotating seat 4, when the sliding column 1402 slides in the guide groove 1404, the drive sleeve 1403 can be driven to rotate. The compression spring 1406 will push the card plate 1405 to make it close to the ratchet ring 1407, so that the card plate 1405 can drive the ratchet ring 1407 to rotate synchronously, and the rotating seat 4 can rotate a quarter of a turn, so that the blank after loading can be rotated to the bottom for heating treatment, and the blank after heating treatment below can be moved to the movable mold 11 for extrusion molding treatment, and when the motor 6 drives the screw 7 to rotate, so that the driving plate 8 drives the ejector 9 to extrude the blank, the driving plate 8 drives the transmission rod 1401 to move together, and similarly the driving sleeve 1403 will rotate in the opposite direction. At this time, the one-way bearing 3 will prevent the rotating seat 4 from rotating in the opposite direction, and the card plate 14 05 will squeeze the compression spring 1406 and slide with the ratchet ring 1407, so the rotating seat 4 will not be driven to rotate during the extrusion process, so that the position of the rotating seat 4 can be automatically controlled during the reciprocating extrusion process to feed the material, and in the extrusion process, the buffer spring 10 can push the movable mold 11 to block the end of the blank, and as the driving plate 8 continues to move, the ejector rod 9 can slide in the movable mold 11 and move to the fixed mold 5 to form an O-shaped extrusion port, and the subsequent fixed cylinder 12 will contact the movable mold 11, thereby pushing the movable mold 11 to extrude the blank, so that the formed heat dissipation pipe falls into the feed port on the other side. The unloading is carried out on the conveyor. During this process, the driving plate 8 will also drive the feeding rod 1301 to move to the limit frame 1305, so that the push plate 1302 moves the blank inside the limit frame 1305 to the inner lining tube 1501. Therefore, there is no need to add an additional power source to automatically load the materials. When the motor 6 controls the driving plate 8 to move back, the push plate 1302 can be moved out of the limit frame 1305, and the rod-shaped blanks above can be automatically filled into the limit frame 1305 under the action of gravity. At the same time, the material guide frame 1304 is inclined, so that the rod-shaped blanks can automatically move to the limit frame 1305 under the action of gravity, thereby facilitating the loading operation of the blanks one by one.

[0033] See also Figure 1 , Figure 5 and Figure 8, a heating component 15 is arranged inside the outer end of the other side of the rotating seat 4, and the heating component 15 includes an inner lining tube 1501, a heating coil 1502 and a connecting terminal 1503. The inner lining tube 1501 is arranged inside the other end of the rotating seat 4, and the outer side of the inner lining tube 1501 is provided with a heating coil 1502, and the end of the heating coil 1502 is provided with a connecting terminal 1503, and the connecting terminal 1503 is fixedly connected to the rotating seat 4. The heating component 15 also includes a connecting seat 1504, an elastic contact piece 1505 and a power cord 1506. The connecting seat 1504 is fixed inside the lower end of the fixed cover 1303, and the top of the connecting seat 1504 is provided with an elastic contact piece 1505, and the bottom of the elastic contact piece 1505 is electrically connected to the power cord 1506. A material blocking component 16 is connected to one side of the limiting sleeve 2. The material blocking component 16 It includes a fixing ring 1601 and a limiting strip 1602, wherein the fixing ring 1601 is arranged on one side of the limiting sleeve 2, and the limiting strip 1602 is arranged inside the fixing ring 1601, and the limiting strip 1602 is crescent-shaped, the material blocking assembly 16 also includes a pulley seat 1603, a blocking rod 1604 and a return spring 1605, the pulley seat 1603 is arranged on the inner side of the limiting sleeve 2, and the blocking rod 1604 is fixed on one end of the pulley seat 1603, the return spring 1605 is sleeved on the outer side of one end of the blocking rod 1604, and the blocking rod 1604 is slidably connected to the rotating seat 4, the material blocking assembly 16 also includes a baffle 1606 and an avoidance hole 1607, the baffle 1606 is slidably connected to the other side of the rotating seat 4, and the baffle 1606 is fixedly connected to the fixing cover 1303, and avoidance holes 1607 are opened inside at both ends of the baffle 1606;

[0034] The specific operation is as follows: during the rotation of the rotating seat 4, the connecting terminal 1503 will be driven to move together, so that the connecting terminal 1503 at the lower end will contact the elastic contact piece 1505, and the external power supply will enable the heating coil 1502 to work normally through the power line 1506, the elastic contact piece 1505, and the connecting terminal 1503, and utilize the eddy current effect generated by it to heat the blank, so that the blank to be processed is heated while the blank is extruded, thereby saving time, and the original lower connecting terminal 1503 will be separated from the elastic contact piece 1505 due to the rotation of the rotating seat 4, thereby stopping heating, so that the working state of the heating coil 1502 can be automatically controlled without manual switching, saving time and effort, and the fixed cover 1303 made of insulating material can also be used to shield and protect the outside, thereby improving safety performance during use. At the same time, the rotating seat 4 will also drive the baffle rod 1604 to move together. At this time, the reset spring 1605 will push the pulley seat 1603 at the upper end under the limit of the rotating seat 4, so that it can fit tightly with the fixed ring 1601 or the limit strip 1602. Therefore, the limit strip 1602 can be used to change the position of the baffle rod 1604, so that during the process of loading and heating the blank, one end of the blank can be limited to prevent it from moving out of the heating range of the heating component 15. At the same time, the baffle plate 1606 can also be used to limit and cover the other end of the blank to prevent the blank from falling during the rotation of the rotating seat 4. When the heated blank is hot-extruded, since the limit strip 1602 will not block the pulley seat 1603, the baffle rod 1604 can be separated from the end of the blank, so that the top rod 9 can push the blank to the fixed mold 5 for extrusion molding.

[0035] In summary, when using the hot extrusion die for processing aluminum alloy heat dissipation tubes for refrigerators, firstly, a plurality of rod-shaped heat dissipation tube blanks are placed in the material guide frame 1304, and the rod-shaped blanks at the end of the material guide frame 1304 will fall into the lower end of the limit frame 1305. Secondly, when the motor 6 drives the screw 7 to rotate, since the transmission rod 1401 will limit the rotation of the drive plate 8, the position of the drive plate 8 can be controlled, so that the drive plate 8 moves toward the motor 6. At this time, the sliding column 1402 on the transmission rod 1401 will be driven to slide into the guide groove 1404 inside the drive sleeve 1403. Therefore, when the sliding column 1402 slides in the guide groove 1404, the drive sleeve 1403 can be driven to rotate. At this time, the compression spring 1406 will push the card plate 1405 to make it engage with the ratchet. The gear ring 1407 is tightly attached, so that the ratchet ring 1407 can be driven to rotate synchronously through the clamping plate 1405, and the rotating seat 4 can be rotated a quarter of a turn, so that the blank after loading can be rotated to the bottom for heating treatment, and the blank after heating treatment at the bottom can be moved to the movable mold 11 for extrusion molding treatment. Then, when the rotating seat 4 rotates, it will drive the connecting terminal 1503 to move together, so that the connecting terminal 1503 at the lower end contacts with the elastic contact piece 1505, and the external power supply will make the heating coil 1502 work normally through the power line 1506, the elastic contact piece 1505, and the connecting terminal 1503, and use the eddy current effect generated by it to heat the blank. In this process, the rotating seat 4 will also drive the blocking rod 1604 to move together, and at this time, the rotation of the rotating seat 4 will be repeated. The positioning spring 1605 will push the pulley seat 1603 at the upper end under the limit of the rotating seat 4, so that it can fit tightly with the fixing ring 1601 or the limiting strip 1602. Therefore, the limiting strip 1602 can be used to change the position of the baffle 1604, so that during the process of feeding and heating the blank, one end of the blank can be limited, and the baffle 1606 can also be used to limit and cover the other end of the blank. When the heated blank is hot extruded, since the limiting strip 1602 will not block the pulley seat 1603, the baffle 1604 can be separated from the end of the blank. Then, when the motor 6 drives the screw 7 to rotate, so that the driving plate 8 drives the top rod 9 to extrude the blank, the driving plate 8 drives the transmission rod 1401 to move together, and similarly the driving sleeve 1403 will Reverse rotation. At this time, since the one-way bearing 3 will prevent the rotating seat 4 from rotating in the opposite direction, the clamping plate 1405 will squeeze the compression spring 1406 and slide with the ratchet ring 1407. Therefore, the rotating seat 4 will not be driven to rotate during the extrusion process. Afterwards, during the extrusion process, the buffer spring 10 can push the movable mold 11 to close the end of the blank, and as the driving plate 8 continues to move, the ejector rod 9 can slide in the movable mold 11 and move to the fixed mold 5 to form an O-shaped extrusion port. The subsequent fixed cylinder 12 will contact the movable mold 11, thereby pushing the movable mold 11 to extrude the blank, so that the formed heat dissipation pipe falls onto the conveyor on the other side for unloading. In this process, the driving plate 8 also drives the feeding rod 1301 to move toward the limit frame 1305.The push plate 1302 moves the blank inside the limit frame 1305 into the inner liner 1501. Then, when the motor 6 controls the driving plate 8 to move back, the push plate 1302 can move out of the limit frame 1305 again, and the rod-shaped blank above can be automatically filled into the limit frame 1305 under the action of gravity. At the same time, the material guide frame 1304 is inclined, so that the rod-shaped blank can automatically move toward the limit frame 1305 under the action of gravity. Finally, with the movement of the driving plate 8, the rotating seat 4 will be driven to rotate again, so that the lower connecting terminal 1503 moves together, separates it from the elastic contact piece 1505, and stops heating, so that the working state of the heating coil 1502 can be automatically controlled, and the fixed cover 1303 made of insulating material can also be used to cover and protect the outside. The subsequent equipment will repeat the above operation again when working.
