Description

Technical Field

[0001] This utility model relates to the field of tin bar production technology, specifically a casting device for tin bar production. Background Technology

[0002] Solder bars are a type of soldering product, mainly used for electronic, circuit board, and metal soldering. They are divided into two categories: leaded solder bars and lead-free solder bars. Leaded solder bars use a tin-lead alloy with a melting point of 183℃, suitable for wave soldering or hand dip soldering. Lead-free solder bars comply with RoHS standards and commonly use tin-copper or tin-silver-copper alloys with a melting point of 227℃, used in environmentally friendly and export electronic products. Both types of products have their performance improved by adding antioxidants, resulting in good wettability, excellent fluidity, bright and full solder joints, and low dross. During the production of lead-free solder bars, a casting device is required to pour the molten raw material into a mold, allowing the solder bar material to be formed within the mold, ensuring the quality of the solder bar formation.

[0003] In existing solder bar production casting equipment, the casting distribution pipe is fixedly connected to the melting furnace. When casting molds with different numbers of forming slots, the casting distribution pipe cannot be replaced, which cannot meet the casting requirements of different molds. This affects the feeding efficiency of solder bar raw materials, and consequently affects the solder bar casting efficiency. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4This embodiment provides a technical solution: a casting device for tin bar production, including a high-frequency melting furnace 4, a casting channel 5 is provided on the upper edge of the high-frequency melting furnace 4, a casting head 6 is connected to one end of the casting channel 5, a casting distribution pipe 7 is connected to the end of the casting head 6 away from the casting channel 5, casting distribution pipes 8 are provided at equal intervals on the lower side of the casting distribution pipe 7, a connecting ear plate 13 is fixedly installed on the side opposite to the casting head 6 and the casting channel 5, and a level sensor 9 is fixedly installed on the upper side of the high-frequency melting furnace 4.

[0016] like Figure 1-4 As shown, during use, the raw material of the tin bar is loaded into the high-frequency melting furnace 4 and heated and melted by electric heating. The level sensor 9 can measure the level of the raw material. When casting is required, the corresponding casting distribution pipe 7 is fixedly connected to the connecting ear plate 13 on the casting head 6 and the connecting ear plate 13 on the casting channel 5 through the connecting ear plate 13 on the casting head 6. The casting cylinder 1 pushes the horizontal arm 2 and the high-frequency melting furnace 4 to rotate through the rotating shaft 11, so that the raw material melted in the high-frequency melting furnace 4 flows into the casting head 6 through the casting channel 5, and then into the casting distribution pipe 7. Through the casting flow pipes 8 at equal intervals on the lower side of the casting distribution pipe 7, it flows into the forming groove of the mold, thus completing the casting operation. The level sensor 9 can measure the amount of raw material in the high-frequency melting furnace 4 in real time.

[0017] A cross arm 2 is fixedly installed on the outer side of the high-frequency melting furnace 4. A casting cylinder 1 is hinged to the lower side of the end of the cross arm 2 away from the high-frequency melting furnace 4. The casting cylinder 1 provides power for the rotation of the high-frequency melting furnace 4, so that the high-frequency melting furnace 4 can be tilted to pour out the tin bar raw material. The cross arm 2 can transmit the force of the casting cylinder 1 to the high-frequency melting furnace 4, thereby rotating the high-frequency melting furnace 4 through the rotating shaft 11.

[0018] The lower end of the casting cylinder 1 is hinged to a base plate 3. Two support arms 10 are provided on the upper side of the base plate 3 corresponding to the position of the high-frequency melting furnace 4. The support arms 10 can rotate and support the high-frequency melting furnace 4, and the base plate 3 can support the lower end of the casting cylinder 1.

[0019] The upper end of the support arm 10 is rotatably connected to a rotating shaft 11. The end of the rotating shaft 11 facing the high-frequency melting furnace 4 is fixedly connected to a fixed plate 12. The fixed plate 12 facilitates the connection between the rotating shaft 11 and the high-frequency melting furnace 4, thereby rotatably connecting the high-frequency melting furnace 4 to the support arm 10 via the rotating shaft 11.

[0020] The high-frequency melting furnace 4 is connected to the fixed plate 12 by bolts. The fixed plate 12 is welded to the rotating shaft 11. The rotating shaft 11 is connected to the support arm 10 by bearings.

[0021] The casting flow pipe 8 is welded to the casting distribution pipe 7, the casting head 6 is welded to the casting distribution pipe 7, and the level sensor 9 is of the ultrasonic type.

[0022] The working principle of the casting device for tin bar production provided by this utility model is as follows: Figures 1-4 As shown, during use, the raw material of the tin bar is loaded into the high-frequency melting furnace 4 and heated and melted by electric heating. The level sensor 9 can measure the level of the raw material. When casting is required, the corresponding casting distribution pipe 7 is fixedly connected to the connecting ear plate 13 on the casting head 6 and the connecting ear plate 13 on the casting channel 5 through the connecting ear plate 13 on the casting head 6. The casting cylinder 1 pushes the horizontal arm 2 and the high-frequency melting furnace 4 to rotate around the rotating shaft 11, so that the raw material melted in the high-frequency melting furnace 4 flows into the casting head 6 through the casting channel 5, and then into the casting distribution pipe 7. Through the casting flow pipes 8 at equal intervals on the lower side of the casting distribution pipe 7, it flows into the forming groove of the mold, thus completing the casting operation. The level sensor 9 can measure the amount of raw material in the high-frequency melting furnace 4 in real time.
