Description

Technical Field

[0001] The utility model relates to the technical field of casting devices, in particular to a lead-free tin bar casting device capable of changing the length of the lead-free tin bar. Background Art

[0002] Lead-free tin bar is a tin alloy wire that does not contain lead, usually composed of tin, copper, zinc and other elements. Compared with traditional lead-containing tin bar, lead-free tin bar has a higher melting point and better welding performance, and is widely used in the manufacture and maintenance of electronic components. Lead-free tin bar casting device is a device used to produce lead-free tin bar, which is mainly used to melt the lead-free tin bar and inject it into the mold. Lead-free tin bar casting device has the advantages of high production efficiency and stable product quality, and is widely used in the production field of electronic components.

[0003] Lead-free tin bars are cast in the production process, but the existing casting device of lead-free tin bars does not have the function of adjusting the length of the mold, resulting in the need to replace different casting molds when producing lead-free tin bars of different lengths, and a low production rate. When casting multiple molds at the same time, the casting amount is not uniform enough, which may cause the tin bars in several molds to be of different lengths. In addition, the existing casting mode is to directly melt a large piece of tin and then pour it into the mold, and the melting rate is low. When the casting is completed and the tin bar is cooled, the mold needs to be manually placed in water, which is inconvenient. Therefore, in view of the above problems, a lead-free tin bar casting device that can change the length of the lead-free tin bar is proposed. Utility Model Content

[0004] The utility model aims to provide a lead-free tin bar casting device capable of changing the length of the lead-free tin bar, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A lead-free tin bar casting device capable of changing the length of the lead-free tin bar comprises a top plate, a heating box penetrating the top plate is fixedly connected to the top of the top plate, a furnace is fixedly connected to the inner side of the heating box, a crusher is fixedly connected to the top of the heating box, a high-temperature valve is fixedly connected to the bottom end of the furnace, a discharge pipe is fixedly connected to the bottom end of the high-temperature valve, a material equalizing ring is fixedly connected to the bottom end of the discharge pipe, a discharge barrel is fixedly connected to the top end of the material equalizing ring, a feed hole is provided on the side of the material equalizing ring close to the discharge barrel, a casting pipe is fixedly connected to the bottom end of the material equalizing ring, a piston rod is slidably connected to the inner side of the casting pipe, the bottom end of the piston rod is fixedly connected to the bottom plate, and the top end of the bottom plate is fixedly connected to the side plate.

[0007] Preferably, the bottom end of the material equalizing ring is fixedly connected to a water tank, one side of the water tank is fixedly connected to a water pipe that passes through the side plate, the outside of the water pipe is fixedly connected to a water pump that passes through the water pipe, and the water pump is fixedly connected to the side of the side plate away from the water tank, and there are two water pipes and two water pumps.

[0008] Preferably, the number of the discharge tubes is six, the discharge barrel is communicated with the inner side of the casting tube, and the number of the discharge barrels is six.

[0009] Preferably, the number of the feed holes, casting tubes and piston rods is six each, and the top end of the piston rod fits tightly against the inner side of the casting tube.

[0010] Preferably, the side panels are fixedly connected to the bottom edge of the top panel, and there are two side panels.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the device can adjust the length of the lead-free tin bar by setting the discharge pipe, the equalizing ring, the discharge barrel, the feed hole, the casting tube and the piston rod. When producing the lead-free tin bar, the piston rod is adjusted to extend to a suitable length to control the length of the lead-free tin bar. The molten tin water enters the equalizing ring through the discharge pipe and the feed hole. The equalizing ring evenly distributes the tin water to each casting tube. When the tin water solidifies, the piston rod is started again to push the lead-free tin bar out from the inner side of the discharge barrel. This design not only enables the device to adjust the length of the lead-free tin bar, but also enables the device to cast a plurality of molds at the same time. The casting amount is more uniform;

[0013] 2. In the utility model, the rate of melting tin blocks of the device is greatly improved by setting a heating box, a melting furnace, a crusher and a high-temperature valve. A large tin block is poured into the crusher, and the crusher crushes the tin block into tin powder. Then the tin powder enters the inner side of the melting furnace, and the heating box is started. The heating box heats the melting furnace and the tin powder, and the tin powder melts into molten tin. Then the molten tin passes through the high-temperature valve to the next process. This design not only improves the rate of melting tin blocks, but also prevents the molten tin from solidifying prematurely during manual handling.

[0014] 3. In the utility model, the cooling rate of the device is improved by setting a water tank, a water pipe and a water pump. When cooling is required, the water pump is started to pump water into the water tank through the water pipe. The water in the water tank quickly takes away the heat in the casting pipe. Then, another water pump is started to pump the hot water in the water tank through another water pipe. This operation is repeated to ensure that the water temperature in the water tank will not rise. BRIEF DESCRIPTION OF THE DRAWINGS
