[0028] Working principle: During use, when the position of the mold base 9 is replaced, the fastening bolt 15 is taken out from the inside of the limiting bolt 12 and the second abutment plate 14, so that the through plate 13 is taken out from the inside of the connecting card plate 10. After taking it out, the back of the second abutment plate 14 can be separated from the side of the mold base 9 to eliminate the side abutment force of the mold base 9. Then, the position of the limiting bolt 12 is separated from the inside of the connecting card plate 10 and the first abutment plate 11, and then there is no relevant connection force between the connecting card plate 10 and the mold box 3. The connecting card plate 10 can be pulled out from the inside of the mold box 3. After pulling it out, the bottom of the first abutment plate 11 can be separated from the outer surface of the mold base 9, and the top abutment force of the mold base 9 can be eliminated. After eliminating the abutment force on the top and side of the mold base 9, the mold base 9 can be removed from the inside of the mold box 3 to be replaced.

[0029] When winding the steel wire with good integrity, the position of the winding roller 21 can be first sleeved on the outer surface of the connecting rod 20, and then the power of the motor 19 can be used to drive the motor 19 to rotate the position of the winding roller 21, and the formed steel wire can be driven to be wound during rotation. While winding, the power of the electric push rod 17 set on the upper surface of the L-shaped plate 16 can be used to drive the position of the receiving plate 18 at one end of the electric push rod 17 to rise and fall, so that the position of the winding roller 21 can be synchronously raised and lowered, so that the steel wire can be more evenly wound on the outer surface of the winding roller 21 during winding.
