Description

Technical Field

[0001] This application relates to the field of solder product manufacturing technology, and more specifically, to a solder bar casting mold. Background Technology

[0002] Solder bars are welding materials presented in bar form. Their manufacturing process employs molten solder casting technology, where liquid tin alloy is injected into a specialized mold and cooled to solidify, forming standard specifications. This process ensures dimensional accuracy and uniform metal structure in the finished product. For example, Chinese patent CN202221043961.7, a solder bar cooling mold, discloses a technical solution including: a frame with a mold box mounted on it; a cooling chamber for the flow of cooling medium inside the mold box; inlet and outlet holes for the cooling medium to enter or leave the cooling chamber through the outer wall of the mold box; a casting groove on the top surface of the mold box, independently of the cooling chamber; a lifting through-hole on the bottom surface of the casting groove, independently of the cooling chamber; and a push rod inserted through the lifting through-hole, connected to a lifting drive device to lift the workpiece. This application reduces the risk of explosion caused by cooling water contacting the uncooled, high-temperature solder at the push rod point and rapidly vaporizing. This improves the safety of the casting process.

[0003] However, the existing technology has certain limitations in its use. The material collection process after the tin bars are cast and formed is generally limited by the traditional operation mode. After the hot liquid tin metal is cooled and solidified by the mold to form standard-sized tin bars, it often relies on manual collection of each bar, which makes it difficult to reduce the labor intensity. Summary of the Invention

[0004] The purpose of this application is to provide a tin bar casting mold that can solve the technical problems of the limitations of the prior art, where tin bars still need to be collected manually one by one after casting, and the reliance on traditional manual operation mode after liquid tin solidifies, which makes it difficult to reduce labor intensity.

[0005] This application provides a solder bar casting mold, including a mounting frame and a mold box disposed on the mounting frame. The top surface of the mold box is recessed and provided with multiple casting grooves. A first push rod and a second push rod, which can move up and down to lift the solder bar, are disposed through the casting grooves. The top of the mold box is provided with a receiving rod that can move left and right to receive the solder bar. Multiple stop rods are fixedly disposed on the receiving rod. Two of the stop rods are respectively disposed on the front and rear sides of a single casting groove. The mold box is provided with a cooling component for cooling the casting grooves.

[0006] It also includes a first drive assembly, which includes a first cylinder and a first connecting plate. The first connecting plate is fixedly connected to the first push rod. The piston rod end of the first cylinder is connected to the first connecting plate. The first push rod slides through the mounting frame and the mold box and extends into the casting groove.

[0007] The system also includes a second drive assembly, which includes a second cylinder and a second connecting plate. The second connecting plate is fixedly connected to the second push rod. The piston rod end of the second cylinder is connected to the second connecting plate. The second push rod slides through the mounting frame and the mold box and extends into the casting groove.

[0008] The system also includes a transmission assembly, which comprises a connecting frame and a sliding sleeve. The connecting frame is fixedly connected to the receiving rod, and the sliding sleeve is fixedly disposed on the top of the mold box. The connecting frame and the sliding sleeve are slidably connected in a limiting manner.

[0009] The cooling assembly includes a serpentine tube located inside the mold box, with both ends of the serpentine tube extending outside the mold box and fitting against the side wall of the casting tank.

[0010] The mold box is equipped with a guide hopper fixedly on its side.

[0011] The mounting bracket is fixedly equipped with a mounting plate, and both the first cylinder and the second cylinder are fixedly mounted on the mounting plate.

[0012] The mounting bracket has two sliding grooves, and the first connecting plate and the second connecting plate are respectively slidably connected to the corresponding sliding grooves.

[0013] A handle is fixedly installed on the connecting frame.

[0014] The beneficial effects of this utility model are:

[0015] This utility model provides a solder bar casting mold. In use, molten high-temperature solder is poured into a casting tank. The casting tank is cooled by a cooling component, and the high-temperature solder gradually cools and solidifies to form a solder bar. Then, the first push rod moves upward to lift the right side of the solder bar, followed by the leftward movement of the receiving rod to below the right side of the solder bar. Then, the second push rod moves upward to lift the left side of the solder bar until the left side is higher than the right side. Under the action of gravity, the solder bar slides to the right and leaves the mold box. The solder bars are then collected uniformly, completing the solder bar unloading operation. This mold can realize the unified automatic unloading operation of multiple solder bars, eliminating the need for manual handling of each bar, reducing labor intensity, and improving production cycle. The baffles on the front and rear sides of the casting tank form a limiting space to prevent the solder bars from shifting longitudinally and falling, ensuring that the solder bars slide accurately laterally and leave the mold box. The baffles guide and limit the solder bars. Attached Figure Description

[0038] like Figures 1 to 4 As shown, this application embodiment provides a solder bar casting mold, including a mounting frame 1 and a mold box 2 disposed on the mounting frame 1. The top surface of the mold box 2 is recessed and provided with a plurality of casting grooves 21. A first push rod 3 and a second push rod 4 that can move up and down to lift the solder bar 10 are disposed through the casting grooves 21. The top of the mold box 2 is provided with a receiving rod 5 that can move left and right to receive the solder bar 10. A plurality of stop rods 51 are fixedly disposed on the receiving rod 5. Two stop rods 51 are respectively disposed on the front and rear sides of a single casting groove 21. The mold box 2 is provided with a cooling component 6 for cooling the casting grooves 21.

[0039] In use, molten high-temperature solder is poured into casting tank 21. The casting tank 21 is cooled by cooling component 6. The high-temperature solder gradually cools and solidifies to form solder bar 10. Then, the first push rod 3 is moved up to lift the right side of solder bar 10. Then, the receiving rod 5 is moved to the left to below the right side of solder bar 10. Then, the second push rod 4 is moved up to lift the left side of solder bar 10 until the left side of solder bar 10 is higher than the right side. Under the action of gravity, solder bar 10 slides to the right side and leaves mold box 2. Then, the solder bar 10 is collected in a unified manner, and the solder bar 10 unloading operation is completed.

[0040] The mold can realize the unified automatic feeding operation of multiple solder bars 10 without manual picking of each bar, reducing labor intensity and improving production cycle. The baffles 51 on the front and rear sides of the casting tank 21 form a limiting space to prevent the solder bars 10 from shifting longitudinally and falling, ensuring that the solder bars 10 slide accurately laterally to leave the mold box 2. The baffles 51 play a guiding and limiting role for the solder bars 10.

[0041] like Figure 3 and 4 As shown, in this embodiment, a first driving assembly 7 is also included. The first driving assembly 7 includes a first cylinder 71 and a first connecting plate 72. The first connecting plate 72 is fixedly connected to the first push rod 3. The piston rod end of the first cylinder 71 is connected to the first connecting plate 72. The first push rod 3 slides through the mounting frame 1 and the mold box 2 and extends into the casting groove 21.

[0042] When in use, the first cylinder 71 is activated, which drives the first connecting plate 72 to move up and down, and the first push rod 3 moves up and down with the first connecting plate 72.

[0043] like Figure 3 and 4 As shown, in this embodiment, a second drive assembly 8 is also included. The second drive assembly 8 includes a second cylinder 81 and a second connecting plate 82. The second connecting plate 82 is fixedly connected to the second push rod 4. The piston rod end of the second cylinder 81 is connected to the second connecting plate 82. The second push rod 4 slides through the mounting frame 1 and the mold box 2 and extends into the casting groove 21.

[0044] When in use, the second cylinder 81 is activated to move the second connecting plate 82 up and down, and the second push rod 4 moves up and down with the second connecting plate 82.

[0045] like Figures 1 to 4 As shown, in this embodiment, a transmission component 9 is also included. The transmission component 9 includes a connecting frame 91 and a sliding sleeve 92. The connecting frame 91 is fixedly connected to the receiving rod 5, and the sliding sleeve 92 is fixedly disposed on the top of the mold box 2. The connecting frame 91 and the sliding sleeve 92 are slidably connected in a limiting manner.

[0046] When in use, pulling the connecting frame 91 causes the receiving rod 5 to move left and right. The cooperation between the connecting frame 91 and the sliding sleeve 92 guides and limits the connecting frame 91.

[0047] like Figures 1 to 4 As shown, in this embodiment, the cooling component 6 includes a serpentine tube 61, which is located inside the mold box 2 and extends to the outside of the mold box 2 at both ends. The serpentine tube 61 is in contact with the side wall of the casting tank 21.

[0048] During use, the serpentine tube 61 fits evenly against the side wall of the casting tank 21, and the cooling medium (such as water or coolant) circulates through the interfaces at both ends of the serpentine tube 61 to achieve efficient and uniform cooling of the casting tank 21.

[0049] like Figures 1 to 4 As shown, in this embodiment, a guide hopper 22 is fixedly provided on the side of the mold box 2; the guide hopper 22 guides the direction of the tin bar 10 sliding down, which is convenient for subsequent unified collection.

[0050] like Figure 3 and 4 As shown in this embodiment, a mounting plate 11 is fixedly installed on the mounting bracket 1, and the first cylinder 71 and the second cylinder 81 are both fixedly installed on the mounting plate 11; the mounting plate 11 supports and fixes the first cylinder 71 and the second cylinder 81, improving the stability of use.

[0051] like Figure 3 and 4As shown, in this embodiment, the mounting bracket 1 has two sliding grooves 12. The first connecting plate 72 and the second connecting plate 82 are respectively limited and slidably connected to the corresponding sliding grooves 12. The cooperation between the first connecting plate 72, the second connecting plate 82 and the sliding grooves 12 plays a guiding and limiting role for the first push rod 3 and the second push rod 4, restricting the movement trajectory of the first push rod 3 and the second push rod 4.

[0052] like Figures 1 to 4 As shown, in this embodiment, a handle 93 is fixedly provided on the connecting frame 91; the handle 93 makes it easier for the operator to pull the connecting frame 91, improving the ease of use.

[0053] Working principle: When using the solder bar casting mold provided in this application, molten high-temperature solder is poured into the casting tank 21. The serpentine tube 61 is evenly attached to the side wall of the casting tank 21. The cooling medium (such as water or coolant) circulates through the two ends of the serpentine tube 61 to achieve efficient and uniform cooling of the casting tank 21. The high-temperature solder gradually cools and solidifies to form the solder bar 10. Then, the first cylinder 71 is activated to move the first connecting plate 72 upward. The first push rod 3 moves upward with the first connecting plate 72, and the first push rod 3 pushes the solder bar 10 upward. The right side of the solder bar 10 is lifted up, and then the handle 93 is pulled to move the connecting frame 91 to the left. The receiving rod 5 moves to the lower right side of the solder bar 10 along with the connecting frame 91. Then the second cylinder 81 is opened to move the second connecting plate 82 upward. The second push rod 4 moves upward with the second connecting plate 82. The second push rod 4 lifts the left side of the solder bar 10 until the left side of the solder bar 10 is higher than the right side. Under the action of gravity, the solder bar 10 slides to the right side and leaves the mold box 2. Then the solder bar 10 is collected in a unified manner, and the solder bar 10 unloading operation is completed.

[0054] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
