Description

Technical Field

[0001] This invention relates to the technical field of solder bar casting, and in particular to a high-efficiency casting equipment for solder bar processing. Background Technology

[0002] Tin bar processing is the process of turning tin and tin alloy raw materials into standardized bar products through processes such as melting, refining, and forming. Molding sand molds are the core process equipment of sand casting, serving as the "master template" used to replicate the shape, size, and structure of castings. By compacting molding sand onto the surface of the mold, a sand cavity (casting mold) is formed to contain molten metal. Finally, the desired casting is obtained after pouring. Some tin bar processing uses molding sand molds for pouring. During separation, the sand and tin bar are separated, and the sand is then recycled. Compared to using casting molds, tin bars are easier to separate from sand, and the sand can be reused and continuously compacted into molding sand molds for pouring.

[0003] Chinese patent CN220216658U discloses a rapid prototyping device for producing solder bars, relating to the field of solder bar processing. The device includes a support mechanism, a mold mounted on the support mechanism, and an ejection mechanism for ejecting cooled solder bars. By using the ejection mechanism, the user can eject the pre-cast and cooled solder bars from the mold. While waiting for the subsequent molten solder to cool, molten solder can be poured into the empty mold again, thereby saving working time and improving work efficiency.

[0004] The aforementioned related technologies and existing technologies regarding the casting of solder bars have the following drawbacks: When using permanent molds to process solder bars, the mold cavity is damaged as the mold is used for a longer period of time, resulting in reduced casting accuracy. Furthermore, it is not advisable to separate the cast solder bars from the mold. After casting, the solder bars need to be separated from the mold and then cast again, resulting in low efficiency for continuous operation. Summary of the Invention

The upper end bend opening of the conveying cylinder, the molding sand compaction and shaping component and the casting and feeding component are evenly distributed in a circular array around the central axis of the sand storage box.

[0021] Optionally, the notch portion of the notched ring plate is located within a small angle between the casting and unloading component and the upper bend of the conveying cylinder.

[0022] Optionally, a sand sieve is inserted into the inner side of the sand storage box, and the conveying cylinder is coaxially installed inside the sand sieve.

[0029] In summary, the present invention has the following beneficial technical effects: 1. This invention, through the cooperation of structures such as the casting sand mold unit, the casting material feeding component, and the molding sand compaction and shaping component, continuously forms new casting cavities during the cyclical process, ensuring the accuracy of casting. At the same time, after the sand and solder bars fall into the sand storage box, the sand is easily separated from the solidified solder bars, and new sand is added to the empty casting sand mold unit to form new casting cavities, thereby improving the casting efficiency of the work in the cyclical process.

[0030] 2. By setting up a sand screening disc, the molding sand and solder bars falling from the casting sand mold unit fall onto the upper side of the sand screening disc, and then the sand particles fall onto the lower side of the sand screening disc. The solder bars are blocked on the upper side by the sand screening disc, thus separating the sand and solder bars.

[0031] 3. This invention utilizes the coordinated arrangement of a swaying wheel and a vertical support rod. As the swaying wheel rotates, the vertical support rod alternately moves from inside the sliding groove to the outer ring surface of the swaying wheel, causing the sand screening disc to sway up and down. When the vertical support rod moves from the outer ring surface of the swaying wheel to the sliding groove, it falls from the inner wall of the side where the sliding groove intersects perpendicularly with the horizontal axis. The vertical support rod can fall quickly and collide with the sliding groove. The sand screening disc follows and falls synchronously, vibrating under inertia. As the swaying wheel rotates continuously, it vibrates the sand and solder bars supported on the upper side of the sand screening disc, assisting in the separation of the solder bars and sand, and simultaneously breaking up clumps of sand.

[0034] The following is in conjunction with the appendix Figures 1-9 The present invention will be described in further detail below.

[0035] This invention discloses a high-efficiency casting device for tin bar processing. For example... Figures 1-2 As shown, it includes a sand storage box 1, a power sand conveying assembly 2, a rotary support drive assembly 3, a sand casting mold unit 4, a notched ring plate 5, a sand casting and feeding component 6, a sand compaction and shaping component 7, and an upper and lower support drive assembly 8.

[0036] In this embodiment, the shape of the bottom of the molding sand compaction and shaping component 7 corresponds to the shape of the tin bar casting, which can press the molding sand out of the corresponding casting cavity.

[0037] The power sand conveying assembly 2 is coaxially installed inside the sand storage box 1. The power sand conveying assembly 2 can convey sand upward. The upper end of the power sand conveying assembly 2 is curved in an arc. The rotary support drive assembly 3 is installed on the outside of the power sand conveying assembly 2.

[0038] Multiple casting sand mold units 4 are provided. The bottom of the casting sand mold unit 4 can be opened. The casting sand mold unit 4 is connected to the rotary support drive assembly 3. The rotary support drive assembly 3 can control the casting sand mold unit 4 to rotate around the axis of the sand storage box 1.

[0039] The notched ring plate 5 is sleeved and installed on the outside of the power sand conveying assembly 2. When the rotating support drive assembly 3 drives the casting sand mold unit 4 to contact the notched ring plate 5, the bottom of the casting sand mold unit 4 is in a closed state. When the casting sand mold unit 4 is located in the notched part of the notched ring plate 5, the bottom of the casting sand mold unit 4 is in an open state.

[0040] During use, the rotary support drive assembly 3 drives the casting sand mold unit 4 to move gradually above the power sand conveying assembly 2, below the sand compaction and shaping component 7, and below the casting and unloading component 6. The power sand conveying assembly 2 first conveys the sand into the bottom-closed casting sand mold unit 4, and then moves with the rotary support drive assembly 3 to the lower side of the sand compaction and shaping component 7. As the sand compaction and shaping component 7 moves downward, it applies pressure to the sand inside the casting sand mold unit 4, pressing it out of the casting cavity. The casting sand mold unit 4 then rotates again with the rotary support drive assembly 3. The casting mold unit 4 moves to the lower side of the casting and feeding component 6. The casting and feeding component 6 adds casting liquid into the extruded casting cavity. After the solder bar solidifies, the casting sand mold unit 4 rotates again with the rotating support drive component 3. When the casting sand mold unit 4 rotates to the notch range of the notch ring plate 5, the lower end of the casting sand mold unit 4 opens, and the molding sand and solidified solder bar inside fall down into the sand storage box 1. The casting sand mold unit 4 continues to rotate and moves again to the lower end of the discharge port of the power sand conveying component 2 to add molding sand again. At this time, the lower end of the casting sand mold unit 4 is in a closed state.

[0041] The upper and lower support drive assembly 8 is installed on the outside of the sand storage box 1. The upper and lower support drive assembly 8 controls the casting and feeding component 6 and the molding sand compaction and shaping component 7 to move up and down. The casting molding sand mold unit 4 is located below the casting and feeding component 6 and the molding sand compaction and shaping component 7.

[0042] The upper and lower support drive assembly 8 is preferably a hydraulic cylinder.

[0043] The casting and feeding component 6 is located on the upper side of the molding sand compaction and shaping component 7. When the upper and lower support drive components 8 drive the casting and feeding component 6 and the molding sand compaction and shaping component 7 to move downward, when the molding sand compaction and shaping component 7 applies pressure to the molding sand, the casting and feeding component 6 does not contact the molding sand casting cavity below, and the casting and feeding component 6 is connected to the casting liquid supply equipment.

[0044] In this embodiment, as Figure 3 As shown, the power sand conveying assembly 2 includes a conveying cylinder 21, a conveying shaft 22, and a spiral feeding plate 23. The conveying shaft 22 and the spiral feeding plate 23 are coaxially located inside the conveying cylinder 21. The spiral feeding plate 23 is fixedly sleeved on the outside of the conveying shaft 22. The lower end of the conveying shaft 22 rotates through the inner bottom wall of the sand storage box 1. The conveying cylinder 21 is coaxially installed on the inner bottom wall of the sand storage box 1.

[0045] A notch is provided at the connection between the lower end of the conveying cylinder 21 and the sand storage box 1, and the notch ring plate 5 is coaxially installed on the outside of the conveying cylinder 21.

[0046] In this invention, the lower end of the sand storage box 1 is truncated into a cone shape, which makes the sand particles in the sand storage box 1 tend to move towards the axis. Under the pressure of the sand particles on the upper side, the sand particles enter the interior of the conveying cylinder 21 through the notch at the bottom of the conveying cylinder 21, and the spiral feeding plate 23 conveys the sand particles upward as it rotates.

[0047] Multiple casting sand mold units 4 are evenly distributed in a circumferential array around the axis of the conveying cylinder 21. The included angle between the casting and feeding component 6 and the molding sand compaction and shaping component 7 corresponds to the included angle between two adjacent casting sand mold units 4. The upper end of the conveying cylinder 21 is bent in a semi-circular shape. The distance between the upper end bend opening of the conveying cylinder 21 and the axis of the sand storage box 1 is equal to the distance between the molding sand box 41 and the axis of the sand storage box 1. The upper end bend opening of the conveying cylinder 21, the molding sand compaction and shaping component 7 and the casting and feeding component 6 are evenly distributed in a circular array around the central axis of the sand storage box 1.

[0048] During operation, each time the rotating support drive assembly 3 stops driving the casting sand mold unit 4 to move, the upper end bend of the conveying cylinder 21, the sand compaction and shaping component 7, and the casting and unloading component 6 are all equipped with corresponding casting sand mold units 4.

[0049] The notch in the notched ring plate 5 is located within a small angle between the casting material feeding component 6 and the upper bend of the conveying cylinder 21. As the casting sand mold unit 4 moves toward the outlet of the bend end of the conveying cylinder 21 after casting, it first passes through the notch in the notched ring plate 5, causing the bottom of the casting sand mold unit 4 to open, allowing the molding sand and the cast tin bar inside to fall out. Then, the casting sand mold unit 4 moves back to the part of the notched ring plate 5 to close the bottom, and then the conveying cylinder 21 adds sand to the casting sand mold unit 4 after the bottom is closed.

[0050] In this embodiment, as Figures 6-9 As shown, the casting sand mold unit 4 includes a sand box 41, a bottom sealing plate 43, a telescopic frame 44, a rope wheel 45, and a sliding top rod 49.

[0051] The molding sand box 41 is connected to the rotary support drive assembly 3 by two support rods 42. Both the upper and lower ends of the molding sand box 41 are open. The bottom sealing plate 43 is fitted to the lower side of the molding sand box 41. The end of the bottom sealing plate 43 away from the conveying cylinder 21 is rotatably connected to the molding sand box 41.

[0052] The telescopic frame 44 has elastic extension and retraction at both ends. When not subjected to external force, the telescopic frame 44 tends to elastically contract. One end of the telescopic frame 44 is located below the bottom sealing plate 43. After the telescopic end of the telescopic frame 44 extends upward, it slides and fits onto the outside of the support rod 42. The part of the telescopic frame 44 that mates with the support rod 42 is elastically connected to the molding sand box 41. The telescopic frame 44 and the molding sand box 41 are connected by a straight spring, which has the tendency to push the telescopic frame 44 away from the molding sand box 41.

[0053] There are two rope winding wheels 45. The two rope winding wheels 45 are vertically rotatably installed at the bottom of the rotary support drive assembly 3. The outer surface of the rope winding wheel 45 is wound with a winding rope 46. The other end of the winding rope 46 is connected to the bottom sealing plate 43. The winding rope 46 is located on the upper side of the telescopic frame 44. The winding gear 410 is coaxially installed on the lower side of the rope winding wheel 45. The two winding gears 410 are meshed with winding tooth plates 48 on one side close to each other. The end of the telescopic frame 44 away from the bottom sealing plate 43 is connected to the winding tooth plate 48.

[0054] An anti-detachment rod 47 is provided on the side of the winding gear 410 away from the telescopic frame 44. The anti-detachment rod 47 is connected to the adjacent winding tooth plate 48. After the bottom sealing plate 43 seals the bottom of the molding sand box 41, the anti-detachment rod 47 contacts the winding gear 410, reducing the lateral pressure between the teeth of the winding gear 410 and the teeth of the winding tooth plate 48 during the extension of the telescopic frame 44.

[0055] One end of the sliding top rod 49 slides in contact with the outer ring surface of the notched ring plate 5. The telescopic frame 44 and the winding toothed plate 48 are connected at one end and slidably sleeved on the outside of the sliding top rod 49. The other end of the telescopic frame 44 is fixed to the sliding top rod 49. Both ends of the notched ring plate 5 are arc-shaped.

[0056] Preferably, a ball bearing is installed at the end of the sliding top rod 49 away from the telescopic frame 44 to improve the smoothness of the sliding top rod 49 sliding on the outer ring surface of the conveying cylinder 21 and the outer ring surface of the notched ring plate 5.

[0057] During use, the straight spring pushes the telescopic frame 44 away from the molding sand box 41, causing the sliding top rod 49 to contact the outer ring surface of the notched ring plate 5. When the sliding top rod 49 moves from the outer ring surface of the notched ring plate 5 to the outer ring surface of the conveying cylinder 21, the telescopic frame 44 retracts as a whole. During this process, the telescopic frame 44 disengages from the underside of the bottom sealing plate 43. Then, the straight spring pushes the retracted telescopic frame 44 to move towards the axis of the conveying cylinder 21. During the movement, the winding toothed plate 48 engages with the winding gear 410, releasing the winding rope 46 from the outside of the winding wheel 45. The bottom sealing plate 43 gradually opens downwards, causing the molding sand and the cast tin bars in the molding sand box 41 to separate. Then, the sliding top rod 49 moves again into the notch ring plate 5, pushing the sliding top rod 49 to move the telescopic frame 44 away from the conveying cylinder 21, causing the winding tooth plate 48 to move and mesh with the winding gear 410, the winding wheel 45 to wind the winding rope 46, and pulling the bottom sealing plate 43 to seal the bottom of the molding sand box 41. When the telescopic frame 44 moves again, the entire telescopic frame 44 elastically extends, so that one end of the telescopic frame 44 moves to the lower side of the bottom sealing plate 43. Compared with only the support of the winding rope 46, it increases the stable support of the lower side of the bottom sealing plate 43, preventing the bottom sealing plate 43 from opening under pressure when the molding sand inside the molding sand box 41 is pressed into the pouring cavity.

[0058] In this invention, the rotary support drive assembly 3 consists of a meshing gear ring and gear and a support disk. The support disk is rotatably sleeved on the conveying cylinder 21. A bearing is installed between the support disk and the conveying cylinder 21. The gear ring and the support disk are coaxially mounted. The conveying cylinder 21 is equipped with a motor that transmits power to the gear.

[0059] In the invention, a detection controller is installed at the upper end of the conveying cylinder 21 to detect the state of the molding sand inside the lower molding sand box 41 and control the start and stop of the support plate.

[0060] Second embodiment, such as Figures 4-5 As shown, a sand sieve 9 is inserted into the inner side of the sand storage box 1, and the conveying cylinder 21 is coaxially installed inside the sand sieve 9. The sand sieve 9 is set in a conical truncated shape, with a small diameter end at the top. The sand sieve 9 has sand holes that run through the top and bottom.

[0061] After the falling molding sand and solder bars land on the upper side of the sieve plate 9, the solder bars are blocked on the upper side of the sieve plate 9, and the molding sand particles fall to the lower side of the sieve plate 9, separating the solder bars and molding sand.

[0062] The sand screening disc 9 can move up and down inside the sand storage box 1. A vertical rod 10 is fixed on the bottom surface of the sand screening disc 9. The lower end of the vertical rod 10 slides through the bottom wall of the sand storage box 1. The vertical rod 10 is elastically connected to the bottom of the sand storage box 1, preferably by a pressure spring. The vertical rod 10 is located inside the pressure spring, and the pressure spring has a tendency to push the vertical rod 10 downward.

[0063] A drive bevel gear 11 capable of being powered to rotate is installed on the lower side of the sand storage box 1. A motor that applies driving rotation force to the drive bevel gear 11 is installed at the bottom of the sand storage box 1. A coaxial bevel gear 12 is coaxially arranged on the upper side of the drive bevel gear 11. The coaxial bevel gear 12 is coaxially fixed to the lower end of the conveying shaft 22.

[0064] A lateral bevel gear 13 meshes between the coaxial bevel gear 12 and the drive bevel gear 11. A horizontal shaft 14 is coaxially mounted on the lateral bevel gear 13. A wobbling wheel 15 is provided on the lower side of the vertical push rod 10. The wobbling wheel 15 is coaxially mounted with the horizontal shaft 14.

[0065] The circumferential surface of the wobbling wheel 15 has multiple sliding grooves 16 that extend through both end faces. The extension line of the inner wall of one side of the sliding groove 16 intersects the axis of the horizontal axis 14 perpendicularly, while the extension line of the other side of the sliding groove 16 is offset from the axis of the horizontal axis 14.

[0066] During use, the vertical push rod 10 contacts the outer ring surface of the swaying wheel 15 under the elasticity between it and the sand storage box 1 and the pressure of the material on the upper side of the sand screening disc 9. This drives the bevel gear 11 to rotate the horizontal shaft 14 and the swaying wheel 15 through the lateral bevel gear 13. As the swaying wheel 15 rotates, the vertical push rod 10 alternately moves from inside the sliding groove 16 to the outer ring surface of the swaying wheel 15, causing the sand screening disc 9 to sway up and down. When the vertical push rod 10 moves from the outer ring surface of the swaying wheel 15 to the sliding groove 16, it falls from the inner wall of the side where the sliding groove 16 intersects the axis of the horizontal shaft 14 perpendicularly. The vertical push rod 10 can fall quickly and collide with the sliding groove 16. The sand screening disc 9 follows and falls synchronously, vibrating under inertia. As the swaying wheel 15 rotates continuously, it vibrates and separates the sand and tin bars supported on the upper side of the sand screening disc 9, while breaking up the lumps of sand. The smaller sand particles reduce the internal voids in the subsequent compaction and increase the compaction of the compacted molding sand.

[0067] The working principle is as follows: The rotary support drive assembly 3 drives the casting sand mold unit 4 to move gradually above the power sand conveying assembly 2, below the sand compaction and shaping component 7 and the casting material feeding component 6. The upper end of the power sand conveying assembly 2 transports the sand and gravel in the sand storage box 1 to the corresponding bottom-closed casting sand mold unit 4. The upper and lower support drive assembly 8 controls the sand compaction and shaping component 7 to move downwards to apply pressure to the sand in the sand mold unit 4 filled with sand. The sand compaction and shaping component 7 will... The sand material in the casting sand mold unit 4 is pressed out of the casting cavity. The casting material feeding component 6 then adds casting liquid into the pressed casting cavity. After solidification, the rotating support drive component 3 moves the solidified solder bar casting sand mold unit 4 to the notch of the notch ring plate 5. The lower end of the casting sand mold unit 4 opens, allowing the sand and the cast solder bar inside to fall into the sand storage box 1. The power sand conveying component 2 then adds sand material to the empty casting sand mold unit 4 again to carry out continuous casting work.

[0068] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
