[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] A mold fixing device for exothermic welding, such as Figures 1 to 4 As shown,

[0028] include:

[0029] Since exothermic welding is usually used outdoors, and often on unpaved roads, the base plate 1 is made of a heavy metal to ensure its overall stability. Therefore, its high temperature resistance is greater than that of metals such as copper during welding. Also, because there are gaps at the joints between the structures, these gaps can be sealed with other filling materials when using this device. These materials do not affect the normal operation of exothermic welding and can also prevent the high-temperature molten metal from flowing out.

[0030] A support base 10 is fixed to the top of the base plate 1. The top of the support base 10 is provided with a storage groove 11 for easy wire welding. The side wall of the storage groove 11 is used for the welding wire to abut against. Together with the mold body 2 set on the outside of the support base 10, the storage groove 11 and the internal wire are fixed.

[0031] The mold body 2 is slidably connected to the side wall of the support base 10. In order to ensure the connection stability of the mold body 2, four connecting rods 12 are welded to the bottom of the mold body 2. The side wall of the connecting rods 12 is slidably connected to the connecting holes 8. The connecting holes 8 are set on the top of the base plate 1, so that the end of the mold body 2 abuts against the top of the base plate 1, thus completing the fixation of the mold body 2 and the base plate 1.

[0032] The through slots 13 on both sides of the mold body 2 are aligned with the storage slots 11. The connection between the mold body 2 and the base plate 1 completes the fixing of the wire. Two handles 4 are welded on the side wall of the mold body 2 for easy handling during placement. The handles 4 facilitate the movement of the mold body 2 after cooling. Fixing ears 5 are also welded on both ends of the mold body 2. The fixing ears 5 can be clamped with clips similar to those used in kitchens after the exothermic welding process is completed, thus facilitating the separation of the mold body 2 from the base plate 1.

[0033] To facilitate the separation of the mold body 2 from the base plate 1, the connecting rod 12 and the connecting hole 8 are spaced apart to avoid the need for auxiliary fixation during disassembly after connection, thus facilitating operation.

[0034] Two fixing blocks 3 for connection are welded to the top of the base plate 1. The two fixing blocks 3 are symmetrical to the support base 10. An inverted U-shaped connecting frame 7 is welded to the top of the fixing block 3. A threaded rod 16 is threaded to the top of the connecting frame 7. A crossbar is welded to the end of the threaded rod 16 to facilitate the force when rotating. The other end of the threaded rod 16 is rotatably connected to the top of the pressure plate 17. By controlling the rotation of the threaded rod 16 on the top of the connecting frame 7, the connected pressure plate 17 is moved, which facilitates the fixing of the wires inside the storage slot 11 with the fixing blocks 3.

[0035] To ensure the stability of the pressure plate 17, two smooth outer peripheral slide rods 9 are welded to the top of the pressure plate 17. The side walls of the two slide rods 9 are slidably connected to the ends of the connecting frame 7, and the two slide rods 9 are symmetrical relative to the threaded rod 16. Thus, with the cooperation of the slide rods 9, the stable movement of the pressure plate 17 can be ensured.

[0036] The top of the fixing block 3 is also provided with a movable pressure plate 17. The pressure plate 17 cooperates with the fixing block 3 to abut against the wire and fix the wire for exothermic welding. The bottom sides of the mold body 2 are provided with through grooves 13 corresponding to the placement groove 11. The inner wall of the through groove 13 is slidably connected to the side wall of the exothermic wire, so as to facilitate the welding of the exothermic welding material through the round hole 15. With external assistance, the wire placed inside the through groove 13 can be welded after the cover plate 6 is connected to the round hole 15 and the mold body 2, which is convenient for operation.

[0037] A movable groove 14 is provided at the bottom of the mold body 2. The inner wall of the movable groove 14 is also provided with a step that abuts against the support base 10. Through the connection between the mold body 2 and the support base 10, the inner wall of the movable groove 14 is slidably connected to the side wall of the support base 10. Under the action of the connecting hole 8 and the connecting rod 12, the connection and fixation of the two are completed, which is convenient for use.

[0038] The mold body 2 is a conventional instrument. Its working principle, size and model are not related to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. In order to facilitate the inspection, maintenance and parts replacement of the device, the parts inside a single device are usually from the same manufacturer and of the same model, function and batch. The power supply is also common knowledge in the art. In addition, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0039] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

[0040] Working principle

[0041] When using this exothermic welding mold fixing device, first place the base plate 1 on the ground, place the wire to be welded on the top of the fixing block 3, connect one end through the fixing block 3 to the support base 10 welded to the top of the base plate 1, and abut against the storage groove 11 on the top of the support base 10. Then, connect the mold body 2 to the support base 10 and the base plate 1, and fix the mold body 2 by cooperating with the movable groove 14 and through groove 13 inside the mold body 2.

[0042] Finally, rotate the threaded rod 16 to move the pressure plate 17 connected to the threaded rod 16 in conjunction with the sliding rod 9, thus connecting the pressure plate 17 to the fixing block 3 and fixing the wire. Then, open the cover plate 6 and put the auxiliary heat-dissipating welding material into the mold body 2 through the round hole 15, cover the cover plate 6, and complete the welding process of the wire.
