[0002] Tin metal is an important non-ferrous metal, and has a wide application in the fields of electronics, chemical industry, food packaging and the like. With the development of modern industry, the demand for tin metal products is increasing, and the traditional tin metal casting mode has been difficult to meet the large-scale and high-efficiency production demand. Therefore, it is particularly important to develop a device capable of continuously and efficiently casting tin metal.

[0003] The traditional tin metal casting device mostly adopts an intermittent production mode, that is, only one or more fixed molds can be cast each time, the product is taken out after the mold is cooled, and the next casting is carried out. This mode not only has low production efficiency, but also needs a large amount of manual operation, thereby increasing the production cost and labor intensity. In addition, since the heating, cooling and taking out processes of the mold need to consume a certain time, the production cycle of the product is relatively long, and it is difficult to meet the demand of the market for rapid delivery.

[0033] In order to make the utility model's purpose, technical scheme and advantage more clearly, below will combine with the drawing and example, make further detailed explanation to the utility model. It should be understood that the specific example described here is only used to explain the utility model, and is not used to limit the utility model. Based on the example in the utility model, all other examples obtained by the person skilled in the art without making creative labor belong to the scope of protection of the utility model.

[0034] Example 1:

[0035] refer to Figures 1-3 A continuous casting equipment for tin metal includes a worktable 10, on which a cooling zone 14, a mold opening zone 15, and a drive mechanism are correspondingly provided. The mold opening zone 15 is on the left side of the worktable 10, and the cooling zone 14 is on the right side of the mold opening zone 15. A heating furnace 11 is installed on the right side of the worktable 10. A hydraulic cylinder 111 is installed above the heating furnace 11. A heat preservation box 12 is provided on the lower left side of the heating furnace 11. A casting box 121 is installed below the heat preservation box 12. A spout 13 is provided below the casting box 121.

[0036] In the above scheme, the heating furnace 11 melts the tin alloy and stores it inside the furnace. The heating furnace 11 is equipped with a valve structure. The molten tin inside the heating furnace 11 is precisely controlled by a hydraulic cylinder 111 to flow into a heat preservation box 12. The molten tin in the heat preservation box 12 continuously flows into a casting box 121 and then flows down through a spout 13. The molten tin poured into the mold 30 solidifies inside the mold 30 to form a tin product 47.

[0037] refer to Figures 3-5 The workbench 10 has an output shaft 17 rotatably mounted on both sides. A driven disk 19 is provided on one side of the output shaft 17. The driven disk 19 is connected to the drive mechanism. A chain disk 18 is mounted on the output shaft 17. A chain 21 is fitted on the chain disk 18.

[0038] In the above scheme, the drive mechanism includes a geared motor 16, which is fixed below the worktable 10. The output end of the geared motor 16 is connected to the driven disk 19 by a chain. The chain 21 on the chain disk 18 is wound in a ring around the chain disk 18. The geared motor 16 is started by controlling the chain to drive the driven disk 19 to rotate, thereby rotating the chain disk 18. The chain disk 18 drives the chain 21 to circulate on the chain disk 18.

[0039] refer to Figures 3-6 A base plate 22 is mounted on the chain 21. A slide rail 23 is symmetrically arranged on the base plate 22. A slider 24 is symmetrically mounted on the slide rail 23. Side plates 25 are fixed at both ends of the base plate 22. A guide rod 26 is fixed in the middle of one side of the slider 24. Positioning rods 29 are symmetrically arranged on both sides of the guide rod 26. The positioning rods 29 slide through the side plates 25. A fixing rod 27 is vertically arranged at the end of the guide rod 26. A pulley 28 is installed below the fixing rod 27. A mold 30 is detachably mounted on the slider 24. A guide mold assembly is installed on the mold opening area 15. The pulley 28 and the guide mold assembly cooperate with each other.

[0040] In the above scheme, the slider 24 can slide freely on the slide rail 23. The side plate 25 adopts a U-shaped structure, and the two ends of the U-shape of the side plate 25 are slidably penetrated by the positioning rod 29. This improves the stability of the slider 24's movement through the positioning rod 29. When both sliders 24 move inward simultaneously, the two molds 30 fit together to achieve the mold closing process; conversely, when both sliders 24 move outward simultaneously, the mold opens. During the mold opening process, the chain 21 circulates and drives the base plate 22 into the mold opening area 15. The pulley 28 at the end of the guide rod 26 moves and contacts the guide mold assembly, which gradually opens the two molds 30 to complete the mold opening.

[0041] refer to Figure 8 The guide module includes an arc-shaped guide block 33, which is located at the corner of the chain 18. One end of the guide block 33 is provided with a guide opening surface 34, and the other end of the guide block 33 is provided with a guide closing surface 36. A smooth surface 35 is provided between the guide opening surface 34 and the guide closing surface 36, and the smooth surface 35 is the opening area.

[0042] In the above scheme, the arc-shaped guide block 33 is set at the corner of the chain 18, that is, the corner position of the chain 21. First, the pulley 28 at the end of the guide rod 26 moves and contacts the guide mold opening surface 34. After the chain 21 circulates, the pulley 28 moves to the smooth surface 35, and the two sliders 24 move outward at the same time. At this time, the two molds 30 are in a fully opened state, that is, the mold opening state (see reference). Figure 6 ); until pulley 28 moves to guide mold closing surface 36, the mold opening process is completed, and the mold gradually closes.

[0043] Further reference Figure 7 A spring 31 is fitted onto the positioning rod 29.

[0044] In a further implementation, when the two sliders 24 move outwards simultaneously, the spring 31 generates compressed and stored potential energy. When the pulley 28 passes the guide mold closing surface 36, the spring 31 releases the stored potential energy, that is, the two sliders 24 move inwards simultaneously to complete automatic mold closing. After the chain 21 cycles, the mold 30 returns to the bottom of the spout 13 for casting, and so on in a continuous cycle.

[0045] Example 2 (in conjunction with Example 1):

[0046] refer to Figure 4 , Figure 8 and then Figure 9 A sprue distribution assembly is also installed on the mold opening area 15, next to the guide mold assembly. The sprue distribution assembly includes a support leg 32, which is fixed inside the worktable 10. A stabilizing plate 40 is fixedly installed on the top of the support leg 32. There are symmetrical fixing blocks 41 on both sides of the stabilizing plate 40. A positioning plate 42 is installed above the fixing blocks 41. A guide plate 43 is installed on the positioning plate 42.

[0047] In the above scheme, there is a gap between the two positioning plates 42, that is, there is also a gap between the guide plates 43 installed above the two positioning plates 42. The gap is used to store the tin product 47. When the pulley 28 contacts the guide mold opening surface 34, the tin product 47 inside the gradually unfolding mold 30 will enter the guide plate 43. That is, the molds 30 unfold one after another, and the tin product 47 behind pushes the tin product 47 in front to move outward to realize the material discharge function.

[0048] Further reference Figure 9 and Figure 10 A feeding frame 44 is installed on one side of the fixed block 41, and a cutting motor 45 is provided on one side of the feeding frame 44. A cutting disc 46 is installed above the cutting motor 45.

[0049] In a further implementation, the tin product 47 moves towards the lower feed frame 44. As the tin product 47 moves, the tin balls below the tin product 47 enter the range of the cutting disc 46. Under the high-speed rotation of the cutting disc 46, the tin balls are cut and separated, and the tin balls fall into the feed frame 44, while the excess tin product 47 above is discharged from the guide plate 43.

[0050] It is worth noting that the mold 30 in the figure produces solder balls; based on the detachable mold 30, it is only necessary to replace different molds 30, such as solder hemispheres, solder bars and other shapes of molds 30, to achieve multi-purpose use of one machine, so as to produce different types of solder products 47 through one machine.

[0051] The specific implementation process of this utility model is as follows:

[0052] Step 1: The tin alloy is melted in the heating furnace 11 and stored inside the heating furnace 11. The heating furnace 11 is equipped with a valve structure. The molten tin inside the heating furnace 11 is precisely controlled by the oil cylinder 111 to be put into the heat preservation box 12. The molten tin in the heat preservation box 12 flows continuously into the casting box 121 and finally flows continuously into the mold 30 through the spout 13.

[0053] Step 2: The geared motor 16 drives the chain 21 to move continuously in a ring. The molds 30 are mounted one on one on the ring chain 21 to form a row of overall movement. When the molds 30 move to the molten tin nozzle 13, online continuous casting is achieved. The casting effect is achieved by controlling the speed of the geared motor 16.

[0054] Step 3: The molten tin enters the mold and follows the mold 30 smoothly through the cooling zone 14 to achieve cooling and shaping, and then goes to the mold opening zone 15 to achieve automatic mold opening and material discharge; during the mold opening process, the chain 21 moves in a cycle to drive the base plate 22 into the mold opening zone 15. First, the pulley 28 at the end of the guide rod 26 moves and contacts the guide mold opening surface 34. After the chain 21 moves in a cycle, the pulley 28 moves to the smooth surface 35, and the two sliders 24 move outward at the same time. At this time, the two molds 30 are in a fully opened state until the pulley 28 moves to the guide mold closing surface 36, and the mold opening process is completed.

[0055] Step 4: When the pulley 28 passes the guide mold closing surface 36, the spring 31 releases the stored potential energy, that is, the two sliders 24 move inward at the same time to complete the automatic mold closing. After the chain 21 cycles, the mold 30 returns to the bottom of the spout 13 for casting, and so on in a repeated cycle.

[0056] Step 5 (referencing Step 3): When the pulley 28 contacts the guide mold opening surface 34, the tin product 47 inside the gradually unfolding mold 30 will enter the guide plate 43. That is, one mold 30 after another unfolds, and the tin product 47 behind pushes the tin product 47 in front to move outward to achieve the material discharge function.

[0057] Step Six (referencing Step Five): The tin product 47 moves towards the lower feed frame 44. As the tin product 47 moves, the tin balls below the tin product 47 will enter the range of the cutting disc 46. Under the high-speed rotation of the cutting disc 46, the tin balls are cut and separated, and the tin balls fall into the feed frame 44, while the excess tin product 47 above is discharged from the guide plate 43.
