Abstract
Description
Technical Field
[0001] This application relates to the field of tin pillar production, and in particular to a tin pillar casting cooling device that is easy to maintain. Background Technology
[0002] In the manufacturing process of solder wire, after the tin-lead alloy is fused, the purified molten tin is poured into a solidification mold for casting. During the solidification process, the molten tin gradually solidifies, forming a tin pillar. The tin pillar then undergoes forging, extrusion, and wire drawing to obtain the final solder wire.
[0003] Because the temperature of the molten tin is too high, if the casting tube is exposed to a high-temperature environment for a long time, it may be affected by the high temperature, leading to a decline in the material properties of the casting tube, or even cracking or wear. Therefore, in order to ensure the quality of the tin pillar, the casting tube needs to be disassembled and replaced in a timely manner.
[0004] However, in existing tin pillar casting cooling devices, a fixing ring is fitted onto the end of the casting tube furthest from the shell, and several bolts are installed on the fixing ring. Threaded holes are opened on the top of the shell to mate with each bolt. When the bolts are fitted into the threaded holes, they can fix the casting tube. If the casting tube is damaged, workers can unscrew the bolts from the threaded holes and replace the casting tube.
[0005] Each time the casting tube is disassembled, the workers need to first loosen the bolts on the casting tube, then unscrew the bolts from the threaded holes, and finally remove the casting tube from the mold. Each time it is assembled, the bolts need to be screwed into the corresponding threaded holes. The process of disassembling or assembling the casting tube is cumbersome, which reduces the efficiency of disassembling or assembling the casting tube and the efficiency of tin pillar casting. Utility Model Content
[0006] To facilitate the disassembly and assembly of the casting tube, a tin pillar casting cooling device that is easy to maintain is provided.
[0007] The above-mentioned objective of this application is achieved through the following technical solution:
[0008] A tin pillar casting cooling device with convenient maintenance includes a housing with an inlet pipe and an outlet pipe connected to both ends of the housing. The housing contains a cooling chamber connected to the inlet and outlet pipes. A fixing hole is provided at the top of the housing and is connected to the cooling chamber. The device also includes a casting assembly, which includes a casting tube and a clamping block. The clamping block is fixedly connected to the outer peripheral wall of the casting tube. A sliding cavity is formed on the wall of the fixing hole along its circumferential direction. The sliding cavity is an annular shape coaxial with the fixing hole. An insertion port is formed on the side of the sliding cavity away from the cooling chamber along the axial direction of the fixing hole. One end of the insertion port is connected to the sliding cavity, and the other end penetrates the side of the housing opposite to the cooling chamber. A spring is installed at the bottom of the housing, with one end of the spring abutting against the casting tube.
[0009] By adopting the above technical solution, when the casting pipe is damaged after long-term use, press the casting pipe on the side away from the shell, and then rotate the casting pipe. When the locking block on the casting pipe is aligned with the socket, the casting pipe can be removed, facilitating its disassembly. When the casting pipe needs to be assembled, insert the casting pipe into the fixing hole, align the locking blocks on both sides of the casting pipe with the socket, insert the locking block into the socket, and then press the casting pipe on the side away from the shell to slide the locking block in the sliding cavity. The bottom of the casting pipe abuts against one end of the spring, and the spring applies a reaction force to the casting pipe, pressing it into the sliding cavity, facilitating its assembly. The casting pipe can be assembled and disassembled without the use of other tools, making the operation more convenient and improving the maintenance efficiency of the casting pipe.
[0010] Optionally, the housing has a sealing groove on the side facing the cooling chamber, and the housing also includes a sealing ring. The sealing ring is fitted over the casting pipe, and the outer edge of the sealing ring is embedded in the sealing groove. The inner edge of the sealing ring abuts against the side wall of the casting pipe.
[0011] By adopting the above technical solution, after the casting pipe is inserted into the fixing hole, there will be a gap between the casting pipe and the fixing hole. When the mold needs to be flipped, the water in the cooling chamber will flow out from the gap. Therefore, a sealing ring is added to prevent the water in the cooling chamber from flowing out from the gap when the mold is flipped.
[0012] Optionally, the inner edge of the sealing ring is provided with an annular boss, which abuts against the side wall of the casting pipe. The side of the annular boss facing away from the cooling cavity is a guide surface, which gradually contracts from the outside to the inside of the cooling cavity.
[0013] By adopting the above technical solution, when the casting pipe is inserted into the cooling chamber through the fixing hole, the side wall of the casting pipe abuts against the guide surface. The guide surface is set as an inclined surface, which reduces the friction between the side wall of the casting pipe and the guide surface, making it easier for the casting pipe to be inserted into the cooling chamber. After long-term use, it avoids direct contact between the casting pipe groove wall and the sealing ring, which could cause the sealing ring to fall off.
[0014] Optionally, a limiting groove is provided on the side of the sliding cavity away from the cooling cavity, with one end of the limiting groove communicating with the sliding cavity and the other end away from the sliding cavity not penetrating the housing.
[0015] By adopting the above technical solution, the limiting groove restricts the position of the locking block, and the locking block is fixedly connected to the casting pipe, further restricting the movement of the casting pipe within the shell; when the locking block is embedded in the limiting groove, the movement space of the locking block in the limiting groove is reduced, preventing the locking block from moving within the limiting groove, avoiding the locking block from driving the casting pipe to move, and improving the stability of the structure.
[0016] Optionally, an annular limiting plate is installed at the bottom of the housing, and the spring is located inside the annular limiting plate.
[0017] By adopting the above technical solution, after long-term use, the spring will undergo continuous compression and expansion, which may lead to vertical axial deformation. By installing the spring inside the annular limiting plate, the annular limiting plate limits the spring, preventing deformation and reducing the connection stability of the casting pipe.
[0018] Optionally, the housing further includes a dustproof component, which includes a cover plate and a fixed shaft. The cover plate covers the port through which the insertion port passes through the housing and connects to the outside. The fixed shaft is fixed to the surface of the housing, and the cover plate is rotatably connected to the fixed shaft with the fixed shaft as the axis.
[0019] By adopting the above technical solution, when the molten tin is injected into the casting tube, the cover plate prevents the molten tin and other impurities splashed from the casting tube from falling into the socket, preventing the socket and sliding cavity from becoming blocked, and improving the efficiency of the assembly and disassembly of the casting tube.
[0020] Optionally, a protrusion is installed on one side of the cover plate, and a groove is formed on the surface of the housing to engage with the protrusion.
[0021] By adopting the above technical solution, after the molten tin cools and forms a tin pillar, the mold needs to be flipped to remove the tin pillar. During the mold flipping process, the cover plate will rotate, and the protrusion and the groove will engage, which will prevent the cover plate from rotating and improve the stability of the structure.
[0022] Optionally, the outer peripheral sidewall of the casting pipe on the side away from the shell is provided with anti-slip texture.
[0023] By adopting the above technical solution, when the casting pipe needs to be screwed in or out during assembly and disassembly, anti-slip textures are added. When rotating the casting pipe, the friction of the rotating casting pipe is increased, making it easier and less labor-intensive to screw in and out of the casting pipe, improving the efficiency of assembly and disassembly, and enhancing the user experience of the equipment.
[0024] In summary, this application has at least the following beneficial effects:
[0025] 1. Press the casting tube away from the top of the shell and slide it in the sliding cavity to change the position of the locking block on the outer side wall of the casting tube. During assembly, the locking block is embedded in the limiting groove to fix the position of the casting tube. During disassembly, the locking block is pulled out from the sliding cavity and the socket in sequence. The casting tube can be assembled and disassembled without the use of other tools, making the operation more convenient and improving the maintenance efficiency of the casting tube.

[0034] The following section provides a more detailed description, in conjunction with the accompanying diagrams:
[0035] As attached Figure 1 As shown, a tin pillar casting cooling device that is easy to maintain includes a housing 1, a cooling component 2, a casting component 3 located on top of the housing 1, and a connecting component 4.
[0036] The connecting component 4 includes a support frame 41, a base 42, a rotating shaft 43, a support seat 44, and a handle 45.
[0037] There are two support frames 41 here, both of which are trapezoidal in shape. A support base 44 is installed between the two support frames 41, and the support base 44 is located on top of the support frame 41.
[0038] There are two rotating shafts 43 here. The two rotating shafts 43 are located on both sides of the housing 1. One end of the rotating shaft 43 is fixedly connected to the housing 1, and the other end of the rotating shaft 43 passes through the support base 44 and is rotatably connected to the support base 44. The rotatable connection between the rotating shaft 43 and the support base 44 enables the housing 1 to flip on the support base 44.
[0039] The handle 45 is fixedly connected to the side of the housing 1 facing away from the casting tube 31. Pulling the handle 45 can more easily cause the housing 1 to rotate on the support base 44.
[0040] A base 42 is also installed between the two support frames 41. The base 42 is fixedly connected to the bottom of the two support frames 41. When the molten tin is cooled and formed, the shell 1 is flipped on the support seat 44 via the rotating shaft 43. The base 42 catches the falling tin pillars to prevent them from rolling or being impacted when they fall to the ground.
[0041] As attached Figure 1 and attached Figure 2 As shown, the cooling assembly 2 includes an inlet pipe 21, an outlet pipe 22, and a cooling chamber 23.
[0042] The bottom of the housing 1 is connected to the two ends of the water inlet pipe 21 and the water outlet pipe 22. The water inlet pipe 21 and the water outlet pipe 22 are both located inside the two rotating shafts 43, and the water inlet pipe 21 and the water outlet pipe 22 are coaxially aligned with the rotating shafts 43.
[0043] The cooling chamber 23 is located inside the housing 1. The cooling chamber 23 is connected to the water inlet pipe 21 and the water outlet pipe 22. The cold water in the water inlet pipe 21 flows into the cooling chamber 23, and the water in the cooling chamber 23 flows out from the water outlet pipe 22, thereby realizing water circulation in the housing 1 and thus accelerating the cooling of the solder pillar.
[0044] As attached Figure 2 and attached Figure 3 As shown, the casting component 3 includes a casting pipe 31 and a clamping block 32.
[0045] As attached Figure 3 and attached Figure 4As shown, the locking block 32 is installed on the outer peripheral sidewall of the casting pipe 31. The locking block 32 is square in shape, and there are two locking blocks 32 here. The two locking blocks 32 are symmetrically distributed on the outer peripheral sidewall of the casting pipe 31.
[0046] A through fixing hole 11 is opened on the top of the housing 1, and the fixing hole 11 is connected to the cooling cavity 23. The casting pipe 31 is inserted into the fixing hole 11 and contacts the cooling cavity 23.
[0047] A sliding cavity 13 is provided on the wall of the housing 1 along the circumferential direction of the fixing hole 11. The sliding cavity 13 is a ring coaxial with the fixing hole 11.
[0048] The sliding cavity 13 has a socket 12 on the side away from the cooling cavity 23 along the axial direction of the fixing hole 11. The socket 12 passes through the housing 1 and connects to the outside on the side away from the cooling cavity 23. The side of the socket 12 facing the fixing hole 11 is open, so that the socket 12 communicates with the fixing hole 11.
[0049] There are two insertion ports 12 here. The two insertion ports 12 are symmetrically distributed with the center of the fixing hole 11 as the axis. The opening size of the insertion port 12 that penetrates the shell 1 and connects to the outside is larger than the size of the locking block 12. When the casting pipe 31 passes through the fixing hole 11 and is inserted into the cooling chamber 23, the locking block 12 can enter the sliding chamber 13 along the axis of the fixing hole 11 through the insertion port 12.
[0050] The height of the sliding cavity 13 along the axis of the fixing hole 11 is greater than the thickness of the locking block 12 along the axis of the casting pipe 31, so that after the locking block 12 enters the sliding cavity 13, it can slide circumferentially along the fixing hole 11 within the sliding cavity 13.
[0051] A limiting groove 131 is also provided on the side of the sliding cavity 13 facing away from the cooling cavity 23. The limiting groove 131 is open on the side facing the fixing hole 11 and is connected to the fixing hole 11.
[0052] The side of the limiting groove 131 away from the cooling cavity 13 does not penetrate the housing 1, thus sealing it off. The opening size of the side of the limiting groove 131 that connects to the sliding cavity 13 is equal to the cross-sectional shape of the locking block 12 perpendicular to the axis of the casting tube 31. Therefore, if the locking block 12 slides and aligns with the opening of the limiting groove 131, and the locking block 12 is moved to the outside of the housing 1, the locking block 12 can be locked into the limiting groove 131.
[0053] As attached Figure 4 and attached Figure 5 As shown, the housing 1 has an annular sealing groove 16 on the side facing the cooling cavity 23. The housing 1 also includes a sealing ring 17, which is fitted around the fixing hole 11. The outer edge of the sealing ring 17 is cylindrical, and the outer edge of the sealing ring 17 is embedded in the sealing groove 16 on the side facing the top of the housing 1.
[0054] An annular protrusion 171 is provided on the inner edge of the sealing ring 17, and the annular protrusion 171 abuts against the side wall of the casting tube 31. The side of the annular protrusion 171 facing away from the cooling cavity 23 is a guide surface 172. The guide surface 172 gradually contracts from the outside to the inside of the cooling cavity 23. When the casting tube 31 is inserted into the cooling cavity 23 through the fixing hole 11, the side wall of the casting tube 31 abuts against the guide surface 172. The guide surface 172 is set with a slope to reduce the friction between the side wall of the casting tube 31 and the guide surface 172, making it easier for the casting tube 31 to be inserted into the cooling cavity 23.
[0055] As attached Figure 3 and attached Figure 4 As shown, anti-slip texture 311 is formed on the outer peripheral sidewall of the casting tube 31 away from the shell. The anti-slip texture 311 increases the friction of rotating the casting tube 31, making it easier and less labor-intensive to screw the casting tube 31 in and out, and improving the efficiency of assembly and disassembly.
[0056] The housing 1 also includes a spring 14, an annular limiting plate 15, and a dustproof assembly 18.
[0057] A spring 14 is installed at the bottom of the housing 1. One end of the spring 14 is fixedly connected to the bottom of the housing 1, and the other end of the spring 14 abuts against the casting tube 31. The casting tube 31 applies pressure to the spring 14, and the spring 14 applies a reaction force to the casting tube 31. Since the locking block 32 on the casting tube 31 is locked in the limiting groove 131, the casting tube 31 is not easy to move.
[0058] An annular limiting plate 15 is installed at the bottom of the housing 1, and the spring 14 is located inside the annular limiting plate 15. The annular limiting plate 15 limits the spring 14 to prevent the spring 14 from deforming vertically after long-term use, thereby improving the connection stability of the casting pipe 31.
[0059] As attached Figure 4 and attached Figure 6 As shown, the dustproof assembly 18 includes a cover plate 181 and a fixing shaft 182. The fixing shaft 182 is fixed to the top of the housing 1 by a fixing block 184, and the fixing shaft 182 is located on the side where the socket 12 passes through the housing 1 and connects to the outside.
[0060] One end of the cover plate 181 is rotatably connected to the fixed shaft 182 with the fixed shaft 182 as the axis. When the cover plate 181 rotates with the fixed shaft 182 as the axis, the cover plate 181 covers the port of the socket 12 that passes through the housing 1 and connects to the outside, preventing the molten tin splashed from the casting tube 31 and other impurities from falling into the socket 12 and preventing the socket 12 from being blocked from the sliding cavity 13.
[0061] A protrusion 1811 is installed on the end of the cover plate 181 away from the fixed shaft 182. A groove 183 is opened on the surface of the top of the housing 1. The groove 183 is located on the side where the insertion port 12 passes through the housing 1 and connects to the outside. The groove 183 is located on the side opposite to the fixed shaft 182. The protrusion 1811 is engaged with the groove 183 to prevent the cover plate 181 from rotating and to improve the stability of the structure.
[0062] The working principle of this embodiment:
[0063] When assembling the casting tube 31, insert the casting tube 31 into the fixing hole 11, aligning the two locking blocks 32 with the two insertion ports 12; press down on the end of the casting tube 31 with anti-slip texture 311, insert the two locking blocks 32 into the two insertion ports 12, and let the two locking blocks 32 enter the sliding cavity 13 through the insertion ports 12. At this time, the bottom of the casting tube 31 abuts against and compresses the spring 14; after the two locking blocks 32 are fully inserted into the sliding cavity 13, rotate the casting tube 31 so that the locking blocks 32 slide... The tube slides within the moving cavity 13 until the locking block 32 is directly below the limiting groove 131. Then, the force applied to the casting tube 31 towards the cooling cavity 23 is reduced, the spring 14 recovers its deformation and pushes the casting tube 31 out of the cooling cavity 23. The locking block 32 slides into the limiting groove 131 as the casting tube 31 moves, until the locking block 32 abuts against the side of the limiting groove 131 facing away from the cooling cavity 23, thereby preventing the casting tube 31 from being pushed out of the cooling cavity 23, thus completing the fixing of the casting tube 31.
[0064] After the casting tube 31 is fixed, the purified molten tin is poured into the casting tube 31. The cold water in the cooling chamber 23 carries away the heat from the surface of the casting tube 31 and cools the molten tin.
[0065] When the casting tube 31 needs to be replaced, press the casting tube 31 into the cooling chamber 23, slide the locking block 32 out of the limiting groove 131, and rotate the casting tube 31 while keeping it pressed in so that the locking block 32 slides to align with the socket 12. Then pull the casting tube 31 out axially along the fixing hole 11. The locking block 32 slides out of the fixing hole 11 from the socket 12, and the casting tube 31 can be pulled out smoothly afterward, thus realizing the disassembly of the casting tube 31.
[0066] Therefore, the casting pipe 31 in the easy-to-maintain tin pillar casting cooling device of this application is easy to assemble and disassemble without the need for other tools, which improves the efficiency of tin pillar production.
[0067] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
