Technical Field

[0001] The utility model relates to the technical field of pure tin solidification, in particular to a pure tin solidification device. Background Art

[0002] The solidification process of pure tin involves heating it to a liquid state and then solidifying it through a specific cooling method, which is usually carried out after the smelting and purification of tin. During the preparation process of tin grains, this method is often used in combination with corresponding molds to make tin grains of required specifications, and the obtained tin grains are usually used in the production of solders and chemical agents.

[0003] In the existing pure tin solidification devices for preparing tin grains, the used molds are often installed at the required positions through bolts. However, for preparing tin grains of different specifications, different specifications of molds need to be replaced, and the repeated screwing of bolts makes the disassembly and assembly of the molds time-consuming and laborious, affecting the processing efficiency. In view of this, we propose a pure tin solidification device. Content of the Utility Model

[0025] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0026] A pure tin solidification device, see Figures 1 to 4 , including a bottom plate 1. Four corners of the surface of the bottom plate 1 are fixedly provided with guide rods 2. The top ends of the guide rods 2 are connected to a top plate 3. The outer part of the guide rods 2 is sleeved with a movable support plate 4. A group of hydraulic cylinders 5 are symmetrically arranged at the bottom of the movable support plate 4. A fan assembly 6 is arranged on the rear end face of the movable support plate 4. A group of limiting mechanisms 7 are symmetrically arranged on the upper surface of the movable support plate 4. A mold assembly 8 is clamped inside a group of limiting mechanisms 7. A heating mechanism 9 is arranged in the middle of the top plate 3;

[0027] The limiting mechanism 7 includes a clamping frame 701. A set of clamping frames 701 are symmetrically fixed on the surface of the movable pallet 4. A pull handle 702 is inserted on the side of the clamping frame 701. A limiting rod 703 passes through the middle of the pull handle 702. A spring 704 is connected to the surface of the middle part of the pull handle 702. Among them, the two ends of the spring 704 are respectively connected to the clamping frame 701 and the pull handle 702. The spring 704 is sleeved outside the limiting rod 703. The clamping frame 701 and the limiting rod 703 are fixedly connected. In the utility model, by pulling the pull handle 702 outwards, the end of the pull handle 702 is far away from the mold assembly 8, so as to realize the rapid disassembly of the mold assembly 8. Then, on the basis of pulling the pull handle 702 outwards, the replaced mold assembly 8 is placed between a set of clamping frames 701, and at the same time the pull handle 702 is released. Affected by the pulling force of the spring 704, the end of the pull handle 702 is clamped into the inner side of the replaced mold assembly 8, realizing the rapid limiting of the replaced mold assembly 8, which is relatively convenient.

[0028] It should be noted that the mold assembly 8 includes an upper mold 801. A clamping tube 802 is provided at the top of the upper mold 801. A lower mold 803 is attached to the lower end of the upper mold 801. Among them, the end of the pull handle 702 is clamped inside the side of the lower mold 803. A number of mold grooves 804 are symmetrically opened on the inner sides of the surfaces of the upper mold 801 and the lower mold 803. Further, a flow channel is provided between the mold groove 804 of the upper mold 801 and the clamping tube 802. The mold grooves 804 of the upper mold 801 and the mold grooves 804 of the lower mold 803 that are symmetrically arranged up and down together form a hollow sphere. A set of insertion rods 805 are symmetrically fixed on both sides of the surface of the lower mold 803. A limiting screw ring 806 is threadedly sleeved outside the insertion rod 805. In the utility model, through the cooperation of the insertion rod 805 and the limiting screw ring 806, the upper mold 801 and the lower mold 803 can be effectively assembled, and through the flow channel between the mold groove 804 of the upper mold 801 and the clamping tube 802, it is convenient for the pure tin liquid to fill between the mold groove 804 of the upper mold 801 and the mold groove 804 of the lower mold 803, realizing the shaping of the tin particles.

[0029] It should be noted that the heating mechanism 9 includes a heating tank 901, which is arranged in the middle of the surface of the top plate 3. A motor 902 is provided at the middle end of the top of the heating tank 901. A positioning frame 903 is arranged outside the motor 902. A feed inlet 904 is arranged on one side of the motor 902. The movable end of the motor 902 is connected to a stirring frame 905. A discharge port 906 is arranged at the bottom of the heating tank 901. A heating pipe 907 is connected to the lower end of the discharge port 906. Among them, the heating pipe 907 is fitted and engaged inside the clamping pipe 802. The heating tank 901 is connected to the upper mold 801 through the discharge port 906, the heating pipe 907 and the clamping pipe 802. In the present utility model, pure tin blocks are put into the heating tank 901 through the feed inlet 904. After heating for a period of time, the motor 902 effectively drives the stirring frame 905 to rotate, thereby accelerating the melting of the pure tin blocks, making the melted pure tin liquid evenly heated, reducing the possibility of blocky residues. Then, the valve of the discharge port 906 is opened, and the pure tin liquid enters the heating pipe 907 through the discharge port 906. A heating wire is wound around the inner layer of the heating pipe 907. The heating pipe 907 effectively reheats the pure tin liquid, reducing the possibility of solidification of the pure tin liquid during the transmission process. The pure tin liquid passing through the heating pipe 907 finally enters the upper mold 801.

[0030] Working principle: Replace the required die assembly 8 according to the preparation needs. Pull the handle 702 outwards so that the end of the handle 702 is away from the die assembly 8, thereby realizing the rapid disassembly of the die assembly 8. Then, on the basis of pulling the handle 702 outwards, place the replaced die assembly 8 between a set of holders 701, and at the same time release the handle 702. Affected by the pulling force of the spring 704, the end of the handle 702 is clamped inside the replaced die assembly 8 to realize the rapid positioning of the replaced die assembly 8. Then, put the pure tin block into the heating tank 901 through the feed port 904. After heating for a period of time, drive the stirring frame 905 to rotate by the motor 902, thereby accelerating the melting of the pure tin block, making the melted pure tin liquid evenly heated, reducing the possibility of blocky residue. Drive the movable support plate 4 to move upwards by the hydraulic cylinder 5, so that the electric heating tube 907 is clamped into the clamping tube 802. Then, open the valve of the discharge port 906, and the pure tin liquid enters the electric heating tube 907 through the discharge port 906. There is an electric heating wire wound around the sandwich of the electric heating tube 907. The electric heating tube 907 performs secondary heating on the pure tin liquid to reduce the possibility of the pure tin liquid solidifying during the transmission process. The pure tin liquid passing through the electric heating tube 907 finally enters the upper die 801. The flow channel between the die cavity 804 of the upper die 801 and the clamping tube 802 makes the pure tin liquid fill the die cavity 804 between the upper die 801 and the lower die 803, realizing the shaping of the tin pellets. Then, close the valve of the discharge port 906, and at the same time drive the movable support plate 4 to move downwards by the hydraulic cylinder 5, so that the electric heating tube 907 is separated from the clamping tube 802. Finally, blow and cool the die assembly 8 through the fan assembly 6 to realize the slow solidification of the tin pellets. Separate the upper die 801 from the lower die 803 by removing the limiting retaining ring 806, which is convenient for taking out the tin pellets.
