[0002] With the popularization of smart wearable devices in the consumer field, multifunctional electronic watches, as an important daily life smart device, have gradually attracted widespread attention and love from consumers for their multiple functions, convenience and practicality. The shell of electronic watches not only needs to be lightweight, corrosion-resistant, and impact-resistant, but also needs to meet the requirements of beautiful colors and functionality. The press-forming device is mainly used to process aluminum alloy watch frame structures.

[0003] The patent document with announcement number CN113305165B records an efficient extrusion molding device and method for aluminum alloy products, including a frame, on which a feeding mechanism, an extrusion molding mechanism, a straightening and molding mechanism, an anti-oxidation treatment mechanism and a discharging mechanism are arranged in sequence along the feeding order. The straightening and molding mechanism includes a straightening component and a molding component. The straightening component includes a plurality of straightening rollers rotatably mounted on the frame, and the straightening rollers are provided with straightening grooves adapted to the width of the aluminum profile. The molding component includes an upper conveyor belt and a lower conveyor belt and a conveyor belt driver for driving the upper conveyor belt and the lower conveyor belt to move. The widths of the upper conveyor belt and the lower conveyor belt are adapted to the width of the aluminum profile, and a gap adapted to the height of the aluminum profile is provided between the upper conveyor belt and the lower conveyor belt to shape and convey the aluminum profile.

[0004] The above-mentioned extrusion molding device has certain shortcomings when performing extrusion processing operations on aluminum alloy watch frames. The shapes of aluminum alloy watch frames on the market are different, including circular, rectangular and other shapes. The traditional extrusion molding device cannot be flexibly adapted to the extrusion molding of aluminum alloy watch frames of different shapes, and cannot complete the extrusion operation of multiple groups of aluminum alloy watch frames at a single time; secondly, during the extrusion molding operation of the aluminum alloy watch frame, after a group of materials is extruded, some residual materials will remain in the mold. During subsequent extrusion operations, the residual materials in the mold need to be taken out, which reduces the continuity of the aluminum alloy watch frame processing and affects its processing efficiency; at the same time, the traditional extrusion molding device cannot complete the extrusion positioning operation of multiple materials at the same time, which makes it easy for dislocation to occur when multiple materials are extruded simultaneously, reducing the stability during operation. Summary of the invention

[0005] The purpose of the present invention is to provide an aluminum alloy watch frame extrusion shaping device, which can solve the existing problems.

[0006] The problem to be solved by the present invention is:

[0007] 1. The shapes of aluminum alloy watch frames on the market are different, including round, rectangular and other shapes. Traditional extrusion molding devices cannot be flexibly applied to the extrusion molding of aluminum alloy watch frames of different shapes, and cannot complete the extrusion operation of multiple groups of aluminum alloy watch frames at a time; secondly, during the extrusion molding operation of the aluminum alloy watch frame, after a group of materials is extruded, some residual materials will remain in the mold. During the subsequent extrusion operation, the residual materials in the mold need to be taken out, which reduces the continuity of the aluminum alloy watch frame processing and affects its processing efficiency; at the same time, the traditional extrusion molding device cannot complete the extrusion positioning operation of multiple materials at the same time, which makes it easy to misalign when multiple materials are extruded synchronously, reducing the stability during operation.

[0008] The purpose of the present invention can be achieved through the following technical solutions:

[0009] An aluminum alloy watch frame extrusion shaping device comprises a fixed base and an extruder, wherein the extruder is fixedly mounted on the upper outer surface of the fixed base, a mold frame is movably mounted inside the extruder, and four groups of extrusion molds are mounted on the inner side of the mold frame, the extrusion mold comprises a secondary mold and a main mold, the secondary mold is spliced ​​and mounted on the outer surface of one end of the main mold, a top material plate is movably mounted on one end of the secondary mold, a driving disk is movably mounted on the outer surface of the other end of the main mold, the top material plate and the driving disk are connected by an elastic ejector rod, a lifting support plate for mounting two ingots is arranged on the inner side of the upper end of the fixed base, two groups of grooves are arranged on the inner side of the lifting support plate, and two groups of side rotating baffles are movably mounted on the upper ends of the grooves.

By utilizing the setting of the ejecting disk, the ejecting disk can be driven by the driving disk in cooperation with the elastic push rod, so that the ejecting disk drives the residual material to move outward, thereby making the residual material move out from the inside of the secondary mold and the main mold to avoid the material jamming phenomenon.

[0011] As a further technical solution of the present invention, the extruder and the mold frame are driven by a driving wheel, and a driving rack for cooperating with the driving wheel is provided at the upper end of the mold frame. Sliding bases for cooperating with the mold frame are fixedly installed on both sides of the fixed base, and extrusion dies of different specifications are installed on the inner side of the mold frame, so that it can meet the extrusion operations of aluminum alloy watch frames of different shapes such as round and rectangular shapes. During operation, the driving rack is driven by the driving wheel to drive the driving rack to drive the mold frame to translate. Because four groups of extrusion dies are installed in the mold frame, when two groups of extrusion dies move out to one side of the extruder, the other two groups of extrusion dies are placed inside the extruder, and the setting of the sliding base supports the moved-out mold frame, making it convenient for the extrusion die in the mold frame to discharge the remaining material.

[0014] As a further technical solution of the present invention, a push plate is movably installed on one side of the ejector, and the ejector and the push plate are driven by a pneumatic push rod. Feed hoppers are installed on both sides of the fixed base. The ejector drives the push plate to move horizontally through the pneumatic push rod, so that the push plate pushes the driving disk to move, thereby completing the ejection operation of the residual material.

When two ingots are being loaded, in order to avoid misalignment of the ingots when they are inserted into the extrusion cylinder, the lifting support plate is arranged and the two groups of side rotating baffle plates installed thereon are utilized to play a fixed role in the installation of the two groups of ingots. The lifting plate is in a horizontal position. The user puts the ingot into the feed hopper so that the ingot slides down into the groove of the lifting plate. The two sets of grooves can simultaneously complete the limiting operation of the two ingots. At this time, the side rotating push rod is used to drive the lifting plate to move up so that the two sets of lifting plates are stuck on both sides of the ingot in an eight-shaped shape. At the same time, the position of the ingot is corrected so that the ingot is in a straight position. The hydraulic press is used to drive the hydraulic push rod so that the hydraulic push rod pushes one end of the ingot, thereby inserting the ingot into the extrusion cylinder.

[0016] As a further technical solution of the present invention, a hydraulic press is provided on the upper end of the fixed base located on one side of the extruder, and two hydraulic push rods used in conjunction with the ingot are provided at the output end of the hydraulic press, and a spray hood is fixedly installed on the upper end of the fixed base located on the other side of the extruder, and a nozzle is installed inside the spray hood. The hydraulic press is used to drive the hydraulic push rod, so that the hydraulic push rod pushes the ingot to move, and the nozzle inside the spray hood can cool the extruded aluminum alloy frame.

[0017] As a further technical solution of the present invention, a cutting rack is provided at one end of the spray hood, a knife disc is movably installed on the inner side of the cutting rack, and a discharge hopper is provided on the side of the fixed base at the lower part of the cutting rack.

[0018] As a further technical solution of the present invention, the cutting rack and the cutter disc are driven by a sliding block and a screw rod, the screw rod is movably installed inside the sliding block, the cutter disc is driven by a motor, and the sliding block is driven to move by the rotation of the screw rod, so that the sliding block drives the cutter disc to translate, and the motor is used to independently drive the cutter disc to rotate, thereby completing the cutting process of the two groups of aluminum alloy watch frames.

[0019] Beneficial effects of the present invention:

[0020] 1. By setting an extruder, when the aluminum alloy watch frame extrusion shaping device is used, it cooperates with multiple groups of extrusion dies installed on the mold frame to facilitate the extrusion shaping of multiple groups of aluminum alloy watch frames with different shapes, thereby improving its use range and processing efficiency;

[0021] During operation, extrusion dies of different specifications are installed on the inner side of the mold frame, so that it can meet the extrusion operation of aluminum alloy watch frames of different shapes such as round and rectangular. During operation, the driving wheel is used to drive the driving rack, so that the driving rack drives the mold frame to move horizontally. Because four sets of extrusion dies are installed in the mold frame, when two sets of extrusion dies move out to one side of the extruder, the other two sets of extrusion dies are placed inside the extruder, and the setting of the sliding base supports the moved mold frame, which is convenient for the extrusion die in the mold frame to discharge the remaining material. The user heats the ingot to 400℃ to 500℃ to improve its plasticity, and puts the heated ingot into the feed hopper, so that Two groups of ingots are placed on the upper end of the lifting tray, and the lifting rod is used to drive the lifting tray to move up, so that the lifting tray drives the two groups of ingots to move upward, and one end of the two groups of ingots is aligned with the extrusion barrel. The hydraulic press is used to drive the hydraulic push rod, so that the hydraulic push rod pushes the ingots to move, and the ingots are pushed into the extrusion barrel. In conjunction with the setting of the extrusion die, the ingots are extruded into materials shaped like aluminum alloy watch frames, and the nozzles inside the spray hood can cool the extruded aluminum alloy watch frames. Finally, the cutting rack can be used to cut the extruded material according to the thickness of the aluminum alloy watch frame. The cut aluminum alloy watch frames fall into the discharge hopper and are discharged downward through the discharge hopper.

[0022] 2. By setting a top material plate and a push plate, when the aluminum alloy watch frame extrusion shaping device is used, it has a residual material auxiliary cleaning structure, which can quickly complete the residual material cleaning in the mold structure and improve the processing efficiency of the aluminum alloy watch frame;

[0023] During use, when the extrusion cylinder uses the secondary mold and the main mold of the extrusion mold to extrude and shape the aluminum alloy frame, part of the residual material will be stuck in the secondary mold and the main mold. When another group of ingots is installed, the remaining residual material needs to be taken out. By using the setting of the ejector plate, the ejector plate can be driven by the driving plate in cooperation with the elastic ejector rod, so that the ejector plate drives the residual material to move outward, thereby moving the residual material out from the secondary mold and the main mold to avoid the material jam. When the mold frame moves to one side, a corresponding group of secondary molds and the main mold will be placed between the ejector and the limiting card strip, and the limiting card strip is used to fix the secondary mold. The limiting card strip contacts the convex structures on both sides of the secondary mold. The ejector drives the push plate to translate through the pneumatic push rod, so that the push plate pushes the driving plate to move. When the push plate pushes the driving plate, the driving plate pushes the ejector plate through the elastic ejector rod, and the residual material of the ejector plate is ejected outward. When the ejector plate completes the cleaning of the residual material, the spring setting is used to pull the ejector plate to elastically reset through the elastic ejector rod.

[0024] 3. By setting a lifting support plate, the use of the extruder is optimized in the aluminum alloy watch frame extrusion shaping device, so that it can complete the calibration operation of multiple groups of materials at the same time, thereby improving the processing stability of the aluminum alloy watch frame;

[0025] During operation, when two ingots are being loaded, in order to avoid misalignment of the ingots when they are inserted into the extrusion barrel, a lifting support plate is set up, and the two sets of side-rotating baffles installed thereon can play a positioning role in the installation of the two sets of ingots. During operation, first, the side-rotating ejector rod is used to drive the side-rotating baffle plate to move downward, so that the side-rotating baffle plate is placed in a horizontal state, and the user puts the ingots into the feed hopper so that the ingots slide downward into the grooves of the lifting support plate. The setting of the two sets of grooves can simultaneously complete the limiting operation of the two ingots. At this time, the side-rotating ejector rod is used to drive the side-rotating baffle plate to move upward, so that the two sets of side-rotating baffles are stuck in an eight-shaped shape on both sides of the ingot, and the position of the ingot is corrected at the same time, so that the ingot is in a straight state, and the hydraulic press is used to drive the hydraulic ejector rod so that the hydraulic ejector rod pushes one end of the ingot, thereby inserting the ingot into the interior of the extrusion barrel.

[0036] The technical scheme of the present invention will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. 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.

[0037] like Figure 1-Figure 8 As shown, an aluminum alloy watch frame extrusion shaping device comprises a fixed base 5 and an extruder 8, the extruder 8 is fixedly mounted on the upper outer surface of the fixed base 5, a mold frame 9 is movably mounted inside the extruder 8, and four groups of extrusion dies are mounted on the inner side of the mold frame 9, the extrusion dies comprise a secondary mold 13 and a main mold 16, the secondary mold 13 is spliced ​​and mounted on the outer surface of one end of the main mold 16, a top material plate 20 is movably mounted on one end of the secondary mold 13, a driving disk 18 is movably mounted on the outer surface of the other end of the main mold 16, the top material plate 20 and the driving disk 18 are connected by an elastic ejector rod 17, a lifting support plate 2 for mounting two ingots 10 is arranged on the inner side of the upper end of the fixed base 5, two groups of grooves 28 are arranged on the inner side of the lifting support plate 2, and two groups of side rotating baffles 29 are movably mounted on the upper end of the groove 28.

[0038] To solve the problem of residual material cleaning, Figure 3 As shown, a spring 19 is installed on the outer surface of the elastic ejector 17, and the spring 19 is arranged between the main mold 16 and the driving disk 18. The middle parts of the driving disk 18 and the ejector disk 20 are both provided with circular notches. When the extrusion cylinder 15 uses the secondary mold 13 and the main mold 16 of the extrusion mold to extrude and shape the aluminum alloy frame, part of the residual material will be stuck in the secondary mold 13 and the main mold 16. When another group of ingots 10 is installed, the remaining residual material needs to be taken out. By utilizing the setting of the ejector disk 20, the driving disk 18 and the elastic ejector 17 can drive the ejector disk 20, so that the ejector disk 20 drives the residual material to move outward, thereby moving the residual material out from the secondary mold 13 and the main mold 16 to avoid the material jamming phenomenon.

[0039] like Figure 2As shown, the extruder 8 and the mold frame 9 are driven by a driving wheel 14, and a driving rack 21 used in conjunction with the driving wheel 14 is provided at the upper end of the mold frame 9. Sliding bases 3 used in conjunction with the mold frame 9 are fixedly installed on both sides of the fixed base 5. Extrusion dies of different specifications are installed on the inner side of the mold frame 9, so that it can meet the extrusion operations of aluminum alloy watch frames of different shapes such as round and rectangular shapes. During operation, the driving rack 21 is driven by the driving wheel 14, so that the driving rack 21 drives the mold frame 9 to move horizontally. Because four groups of extrusion dies are installed in the mold frame 9, when two groups of extrusion dies are moved out to one side of the extruder 8, the other two groups of extrusion dies are placed inside the extruder 8, and the setting of the sliding base 3 supports the moved-out mold frame 9, making it convenient for the extrusion dies in the mold frame 9 to discharge the excess material.

[0040] like Figure 4 As shown, three groups of dividing bars 22 are installed on the inner side of the mold frame 9, and several groups of sliding wheels 23 are arranged at the bottom of the mold frame 9. Two groups of extrusion barrels 15 are fixedly installed inside the extruder 8. By utilizing the arrangement of the three groups of dividing bars 22, four groups of mounting grooves are formed on the inner side of the mold frame 9, thereby satisfying the installation operation of four groups of extrusion dies. The arrangement of the sliding wheels 23 can reduce the friction force when the mold frame 9 moves, and the ingot 10 is inserted into the interior of the extrusion barrel 15. The hydraulic push rod 11 is used to extrude the ingot 10, so that one end of the ingot 10 is extruded by the secondary mold 13 and the main mold 16.

[0041] The upper end of the sliding base 3 is provided with a ejector 24 and a limiting strip 26. The number of the limiting strips 26 is two groups. The ejector 24 is located on one side of the limiting strip 26. The upper end of the sliding base 3 is provided with a slide groove used in conjunction with the sliding wheel 23. When the mold frame 9 moves to one side, a corresponding group of sub-molds 13 and main molds 16 will be placed between the ejector 24 and the limiting strip 26. The limiting strip 26 is used to fix the sub-mold 13. The limiting strip 26 contacts with the raised structures on both sides of the sub-mold 13. When the push plate 25 pushes the drive disk 18, the drive disk 18 is prevented from ejecting the extrusion mold from the mold frame 9.

[0042] A push plate 25 is movably installed on one side of the ejector 24, and the ejector 24 and the push plate 25 are driven by a pneumatic push rod. Feed hoppers 1 are installed on both sides of the fixed base 5. The ejector 24 drives the push plate 25 to move horizontally through the pneumatic push rod, so that the push plate 25 pushes the drive disk 18 to move, completing the ejection operation of the residual material.

[0043] To solve the calibration problem of multiple groups of materials, such as Figure 6As shown, the lifting support plate 2 and one end of the side rotating baffle plate 29 are movably connected by a rotating rod, and the two groups of side rotating baffle plates 29 are symmetrically arranged. The lower part of the side rotating baffle plate 29 and the lifting support plate 2 are driven by the side rotating ejector rod 30. One end of the side rotating ejector rod 30 and the side rotating baffle plate 29, as well as the other end of the side rotating ejector rod 30 and the lifting support plate 2 are all movably connected. A lifting rod 27 is arranged at the bottom of the lifting support plate 2. The lifting rod 27 can be used to drive the lifting support plate 2 to move up and down, and the lifting support plate 2 is moved to the feed hopper 1 for loading operation. When two ingots 10 are being loaded, in order to avoid misalignment of the ingots 10 when they are inserted into the extrusion cylinder 15, the lifting support plate 2 is arranged, and the two groups of ingots can be loaded by using the two groups of side rotating baffle plates 29 installed thereon. The installation of 10 plays a positioning role. During operation, first use the side rotating push rod 30 to drive the side rotating baffle 29 to move downward, so that the side rotating baffle 29 is placed in a horizontal state. The user puts the ingot 10 into the feed hopper 1, so that the ingot 10 slides down into the groove 28 of the lifting support plate 2. The setting of the two groups of grooves 28 can simultaneously complete the limiting operation of the two ingots 10. At this time, the side rotating push rod 30 is used to drive the side rotating baffle 29 to move upward, so that the two groups of side rotating baffles 29 are stuck in the shape of an eight on both sides of the ingot 10. At the same time, the position of the ingot 10 is corrected so that the ingot 10 is in a straight state. The hydraulic press 12 is used to drive the hydraulic push rod 11, so that the hydraulic push rod 11 pushes one end of the ingot 10, thereby inserting the ingot 10 into the interior of the extrusion cylinder 15.

[0044] The upper end of the fixed base 5 is located on one side of the extruder 8 and is provided with a hydraulic press 12, and the output end of the hydraulic press 12 is provided with two hydraulic push rods 11 used with the ingot 10, and the upper end of the fixed base 5 is located on the other side of the extruder 8 and is fixedly installed with a spray hood 7, and a nozzle is installed inside the spray hood 7. The hydraulic press 12 drives the hydraulic push rod 11, so that the hydraulic push rod 11 pushes the ingot 10 to move, and the nozzle inside the spray hood 7 can cool the extruded aluminum alloy frame.

[0045] A cutting rack 6 is provided at one end of the spray hood 7, and a knife disc 31 is movably installed on the inner side of the cutting rack 6. A discharge hopper 4 is provided on the side of the fixed base 5 and located at the lower part of the cutting rack 6. The cutting rack 6 can be used to cut the extruded material according to the thickness of the aluminum alloy frame. The cut aluminum alloy frame falls into the discharge hopper 4 and is discharged downward through the discharge hopper 4.

[0046] The cutting frame 6 and the cutter disc 31 are driven by a sliding block 32 and a screw rod 33. The screw rod 33 is movably installed inside the sliding block 32. The cutter disc 31 is driven by a motor. The sliding block 32 is driven to move by the rotation of the screw rod 33, so that the sliding block 32 drives the cutter disc 31 to translate. The motor is then used to independently drive the cutter disc 31 to rotate, thereby completing the cutting process of two sets of aluminum alloy watch frames.

[0047] When in use, the shapes of aluminum alloy watch frames on the market are different, including circular or rectangular shapes, etc. The traditional extrusion molding device cannot be flexibly adapted to the extrusion molding of aluminum alloy watch frames of different shapes, and cannot complete the extrusion operation of multiple groups of aluminum alloy watch frames at a time; secondly, during the extrusion molding operation of the aluminum alloy watch frame, after a group of materials is extruded, some residual materials will remain in the mold. During the subsequent extrusion operation, the residual materials in the mold need to be taken out, which reduces the continuity of the aluminum alloy watch frame processing and affects its processing efficiency; at the same time, the traditional extrusion molding device cannot complete the extrusion positioning operation of multiple materials at the same time, which makes it easy to misalign when multiple materials are extruded synchronously, reducing the stability during operation;

[0048] To this end, by providing an extruder 8, when the aluminum alloy watch frame extrusion shaping device is used, it cooperates with multiple groups of extrusion dies installed on the die frame 9 to facilitate the extrusion shaping of multiple groups of aluminum alloy watch frames with different shapes, thereby improving its use range and processing efficiency;

[0049] During operation, extrusion dies of different specifications are installed on the inner side of the mold frame 9, so that it can meet the extrusion operation of aluminum alloy watch frames of different shapes such as round and rectangular. During operation, the driving wheel 14 is used to drive the driving rack 21, so that the driving rack 21 drives the mold frame 9 to move horizontally. Because four groups of extrusion dies are installed in the mold frame 9, when two groups of extrusion dies move out to one side of the extruder 8, the other two groups of extrusion dies are placed inside the extruder 8, and the setting of the sliding base 3 supports the moved mold frame 9, which is convenient for the extrusion die in the mold frame 9 to discharge the excess material. The user heats the ingot 10 to 400°C to 500°C to improve its plasticity, and puts the heated ingot 10 into the feed hopper 1, so that the two groups of ingots 10 The lifting support plate 2 is placed on the upper end of the lifting support plate 2, and the lifting support plate 2 is driven to move upward by the lifting rod 27, so that the lifting support plate 2 drives the two groups of ingots 10 to move upward, and one end of the two groups of ingots 10 is aligned with the extrusion cylinder 15, and the hydraulic press 12 is used to drive the hydraulic push rod 11, so that the hydraulic push rod 11 pushes the ingot 10 to move, and the ingot 10 is pushed into the extrusion cylinder 15, and the ingot 10 is extruded into a material shaped like an aluminum alloy frame in accordance with the setting of the extrusion die, and the nozzle inside the spray hood 7 can cool the extruded aluminum alloy frame, and finally the cutting frame 6 can be used to cut the extruded material according to the thickness of the aluminum alloy frame, and the cut aluminum alloy frame falls into the discharge hopper 4 and is discharged downward through the discharge hopper 4;

[0050] By providing the ejector plate 20 and the push plate 25, when the aluminum alloy watch frame extrusion shaping device is used, it has a residual material auxiliary cleaning structure, which can quickly complete the residual material cleaning in the mold structure, thereby improving the processing efficiency of the aluminum alloy watch frame;

[0051] When in use, when the extrusion cylinder 15 uses the secondary mold 13 and the main mold 16 of the extrusion mold to extrude and shape the aluminum alloy frame, part of the residual material will be stuck in the secondary mold 13 and the main mold 16. When another group of ingots 10 is installed, the remaining residual material needs to be taken out. By using the setting of the ejector plate 20, the ejector plate 20 can be driven by the driving plate 18 in conjunction with the elastic ejector rod 17, so that the ejector plate 20 drives the residual material to move outward, thereby moving the residual material out of the secondary mold 13 and the main mold 16 to avoid the material jamming phenomenon. When the mold frame 9 moves to one side, the corresponding group of secondary molds 13 and the main mold 16 are The mold 13 and the main mold 16 are placed between the ejector 24 and the limit clip 26. The limit clip 26 is used to fix the secondary mold 13. The limit clip 26 contacts the convex structures on both sides of the secondary mold 13. The ejector 24 drives the push plate 25 to translate through the pneumatic push rod, so that the push plate 25 pushes the driving disk 18 to move. When the push plate 25 pushes the driving disk 18, the driving disk 18 pushes the ejector disk 20 through the elastic ejector rod 17. When the ejector disk 20 completes the cleaning of the residual material, the spring 19 is set to make the driving disk 18 pull the ejector disk 20 to elastically reset through the elastic ejector rod 17.

[0052] By setting the lifting support plate 2, the use of the extruder 8 is optimized in the aluminum alloy watch frame extrusion shaping device, so that it can complete the calibration operation of multiple groups of materials at the same time, thereby improving the processing stability of the aluminum alloy watch frame;

[0053] Since the ingot 10 needs to maintain a high degree of straightness during extrusion to prevent the ingot 10 from being offset during extrusion, the ingot 10 needs to be positioned during extrusion. In the prior art, a positioning groove is usually used to accommodate the ingot 10, thereby achieving the positioning of the ingot 10; however, in the method of positioning by a positioning groove, the size of the positioning groove needs to be consistent with the ingot 10, and the ingot 10 may be deformed due to collision during the transfer process. The deformation will affect the ingot 10 from entering the positioning groove, so that the ingot 10 needs to be squeezed into the positioning groove by external force, which increases the difficulty of loading and easily aggravates the damage of the positioning groove. Moreover, since the size of the positioning groove is fixed, when cooperating with the extrusion of different types of products, the thickness of the ingots 10 used may be different. Therefore, different positioning grooves need to be replaced at the same time, which increases the difficulty of operation and reduces efficiency. During operation, when two ingots 10 are loaded, in order to avoid the misalignment of the ingots 10 when they are inserted into the extrusion cylinder 15, a lifting support plate 2 is provided, and two sets of side rotating baffles 29 installed thereon can be used to position the installation of the two sets of ingots 10. During operation, the side rotating ejector rod 30 is first used to drive the side rotating baffle 29 to move downward, so that the side rotating baffle 29 is placed in a horizontal state, so that The top of the groove 28 is more open, and the user puts the ingot 10 from the feed hopper 1, so that the ingot 10 can slide down more easily into the groove 28 of the lifting support plate 2. The setting of the two groups of grooves 28 can simultaneously complete the limiting operation of the two ingots 10. At this time, the side rotating ejector 30 is used to drive the side rotating baffle 29 to move up, so that the two groups of side rotating baffles 29 are stuck on both sides of the ingot 10 in an eight-shaped shape, and the position of the ingot 10 is corrected at the same time, so that the ingot 10 is in a straight state, and the hydraulic press 12 is used to drive the hydraulic ejector 11, so that the hydraulic ejector 11 pushes one end of the ingot 10, so that the ingot 10 is inserted into the inside of the extrusion cylinder 15;

[0054] In addition, ingots 10 of different sizes can also be adapted by controlling the rotation angle of the two side-rotating baffles 29 (that is, while maintaining the same axial height of the ingot 10, the smaller the diameter of the ingot 10, the smaller the angle between the two side-rotating baffles 29, thereby raising the axial center of the small-diameter ingot 10; conversely, the larger the diameter of the ingot 10, the larger the angle between the two side-rotating baffles 29, thereby lowering the axial center of the large-diameter ingot 10), so there is no need to replace the groove 28.
