Description

Technical Field

[0002] The grid is the main component of the lead-acid battery, and the continuous casting production process is generally adopted. During production, the fixed mold and the movable mold roller need to be matched and fixed. The fixed mold relies on the push of the pressure plate to lean against the movable mold roller. The molten lead liquid from the lead melting furnace is pumped into the lead delivery pipe, and the lead delivery pipe passes through the fixed mold. Part of the lead liquid enters the fixed mold cavity through the through hole of the lead delivery pipe, and is coated on the grid frame moved by the movable mold roller with the help of the lead outlet hole on the side of the fixed mold facing the movable mold. Since the lead liquid in the lead delivery pipe is always in a flowing state, the lead liquid is prevented from solidifying in the fixed mold under working conditions.

[0003] However, during production breaks, the fixed mold needs to be removed for cleaning due to the solidification of the molten lead. The frequent loading and unloading of the fixed mold and the long-term wear between the fixed mold and the fixed structure may cause the fixed mold and the movable mold roller to be misaligned during reinstallation, affecting the forming quality of the grid and requiring fine-tuning of the fixed position of the fixed mold.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0021] Specific implementation examples Figure 1-5 As shown, the utility model provides a fixed mold for continuous casting of a plate grid, comprising a fixed mold body 2 and a lead feeding pipe 3 arranged on a workbench 1, the fixed mold body 2 is a hollow box-shaped structure, one side of the fixed mold body 2 is a concave arc surface matching the movable mold roller, the concave arc surface is provided with a lead outlet hole 4 along the length direction of the fixed mold body 2, the end of the fixed mold body 2 is also provided with a mounting port, the lead feeding pipe 3 is inserted into the inner cavity of the fixed mold body 2 along the mounting port and is fixed, the tube wall of the lead feeding pipe 3 is provided with a through hole 5 facing the lead outlet hole 4 along the length direction, a fixed seat 6 fixedly connected to the fixed mold body 2 is further provided below the fixed mold body 2, a limiting mechanism and an adjusting mechanism are provided at the bottom of the fixed seat 6, the limiting mechanism comprises a limiting block 7 and a limiting convex strip 8 matching in a concave and convex shape, the limiting convex strip 8 is fixed to the surface of the workbench 1, the limiting block 7 is fixed to the fixing seat 6 by means of the adjusting mechanism and has the freedom to translate along the length direction of the fixed mold body 2.

[0022] Currently, during breaks in the production of the grid, the fixed mold needs to be removed for cleaning due to the solidification of the molten lead. In addition, long-term wear between the fixed mold and the fixed structure may cause the fixed mold and the movable mold roller to be misaligned when they are reinstalled, affecting the molding quality of the grid. It is necessary to fine-tune the fixed position of the fixed mold.

[0023] Therefore, the utility model is provided with a limiting mechanism and an adjusting mechanism. When fine adjustment is required to align the fixed mold with the movable mold roller, the limiting block 7 is moved left and right with the help of the adjusting mechanism, so that the limiting block 7 and the fixed seat 6 are relatively displaced, so that the fixed mold is fine-tuned and aligned with the movable mold roller, and then the limiting block 7 is fixedly matched with the limiting convex strip 8.

[0024] like Figure 1As shown, the fixing seat 6 is a convex structure, and two L-shaped baffles 9 are symmetrically arranged on the workbench 1, a fixing groove is formed between the two baffles 9, and the limiting convex strip 8 is located in the middle of the fixing groove. The skirts on both sides of the fixing seat 6 match the fixing groove and form a plug-in match, and the width of the fixing groove is greater than the width of the bottom of the fixing seat 6. The fixing groove will be slightly wider than the base, ensuring that the L-shaped baffles 9 on both sides can press the skirt of the base, ensuring that the base can be easily inserted into the fixing groove, and the horizontal limit is mainly with the help of the limit block 7, which also has a guiding function, so that the base can be accurately inserted into the fixing groove.

[0025] like Figure 1-4 As shown, the adjustment mechanism includes a fixing bolt 10 and a limiting groove 12, the limiting block 7 is fixed in the limiting groove 12, the width of the limiting groove 12 is greater than the width of the limiting block 7, and the limiting block 7 has the freedom to move left and right in the limiting groove 12, the limiting block 7 is provided with a fixing hole 11 penetrating the limiting block 7, the fixing hole 11 is arranged in the vertical direction, the fixing bolt 10 passes through the fixing hole 11 and abuts against the fixing seat 6, and the limiting block 7 is fixed by means of the fixing bolt 10. When fine-tuning the fixed mold, loosen the fixing bolt 10 and fine-tune the position of the fixing seat 6 left and right to align the fixed mold with the movable mold roller, and then re-tighten the fixing bolt 10 to fix the limiting block 7 and the fixing seat 6.

[0026] like Figure 1-3 As shown, a transition pipe is also provided at the installation opening of the fixed mold body 2, and the transition pipe includes a pipe body 13 and a threaded joint 14. The threaded joint 14 is fixedly connected to the fixed mold body 2 by means of the pipe body 13, and the threaded joint 14 is threadedly connected to the lead delivery pipe 3. During production breaks, the lead delivery pipe 3 also needs to be disassembled from the threaded joint 14. Therefore, the lead delivery pipe 3 will be frequently installed and disassembled from the threaded joint 14. During the installation and disassembly process, the threads of the threaded joint 14 will be worn, which will affect the sealing between the lead delivery pipe 3 and the threaded joint 14, and may In case of lead liquid leakage, the threaded joint 14 needs to be replaced regularly, but the threaded joint 14 of the traditional grid fixed mold is directly welded to the fixed mold body 2. The fixed mold body 2 may be damaged when the threaded joint 14 is replaced. Therefore, the utility model is provided with a transition pipe. When replacing, the threaded joint 14 is cut off along the connection between the pipe body 13 and the threaded joint 14, and then the new threaded joint 14 is welded to the cross section. This structure makes the cross section of the cut threaded joint 14 away from the fixed mold body 2, thereby avoiding the possibility of damaging the fixed mold body 2 when replacing the threaded joint 14.

[0027] like Figure 1-3 and Figure 5As shown, the inner cavity of the fixed mold body 2 is also provided with a heating device 15, and the end of the fixed mold body 2 is provided with a heating port, and the heating device 15 extends into the inner cavity of the fixed mold body 2 through the heating port and is fixed. The utility model is also provided with a heating device 15, and the heating device 15 can be an electric heating resistance wire, which continuously heats the lead liquid in the lead delivery pipe 3 to prevent the lead liquid from solidifying.

[0028] like Figure 1-3 and Figure 5 As shown, the heating device 15 is provided with multiple groups, and the multiple groups of heating devices 15 are arranged in a ring shape around the lead delivery tube 3. The lead delivery tube 3 is heated by wrapping it with multiple groups of electric thermal resistance wires to ensure that the lead delivery tube 3 is heated evenly.

[0029] In addition, Figure 1-3 As shown, the utility model is also provided with a nitrogen delivery pipe 16, a lead return pipe 17 and a rib 18. The rib 18 is arranged on a concave arc surface. The rib 18 is used to be embedded in the cavity of the grid to prevent excessive lead liquid in the grid cavity from affecting the uniformity of the grid. Inert gas protection holes are evenly distributed on the nitrogen delivery pipe 16. The inert gas protection holes and the ribs 18 are alternately distributed. The nitrogen delivery pipe 16 will transport nitrogen and other stable gases to reduce the contact between the lead liquid and oxygen in the air during the continuous casting of the grid, reduce the impurity content in the grid, and improve the quality of the grid. The lead return pipe 17 is connected to the end of the lead delivery pipe for recovering the lead liquid.
