Description

Technical Field

[0001] The utility model relates to the technical field of exothermic welding dies, in particular to an exothermic welding die which is convenient for replacing workpieces. Background Art

[0002] The exothermic welding mold is made of high-purity graphite and is used for grounded exothermic welding welding head molding. A complete mold consists of a mold body, a top cover, and a hinge. It is very suitable for welding cables and other metal components in the field, and is suitable for welding copper core cables to steel structures or connecting copper core cables during the installation of cathodic protection systems.

[0003] In the existing exothermic welding mold, the upper mold base is connected to the lower mold base by a hinge. Therefore, if you want to replace the upper mold base, you must first use a tool to remove the hinge to separate the upper mold base and the lower mold base. According to the Chinese utility model disclosure patent CN216802083U, a modular exothermic welding mold is disclosed. The magnet inside the unlocker can adsorb the inner sleeve. When the unlocker is installed on the top of the fixed sleeve, the magnet inside it will attract the inner sleeve to move upward. When the inner sleeve moves upward, the gap between the extrusion balls inside it will become larger, so that the gap between the extrusion balls is larger than the diameter of the connecting rod, thereby allowing the fixed sleeve to be removed from the connecting rod, and finally realizing the function of separating the upper mold base from the first lower mold base and the second lower mold base.

[0004] The existing exothermic welding mold is not convenient for replacing the upper mold base, and the hinge needs to be removed with the help of tools to separate the upper and lower mold bases. As shown in the above-mentioned patent, although it solves this problem, in actual use, it is separated by magnetic adsorption. Long-term use will cause the magnetism of the magnet to decrease, resulting in the device being unable to be used normally, and lacks certain practicality. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1

[0029] See also Figure 1-5, an exothermic welding mold for facilitating the replacement of workpieces, comprising a main body component 1; the main body component 1 comprises a lower mold 11, a front surface of which is provided with a placement hole 14; a handle 12, fixedly connected to the rear surface of the lower mold 11, and provided with two groups; an upper mold 13, arranged on the top of the lower mold 11; a disassembly component 2 is arranged on the lower mold 11, and the disassembly component 2 comprises: a fixing plate 21, fixedly connected to the outer side wall of the lower mold 11; a fixing buckle 22, symmetrically fixedly connected to the outer side wall of the lower mold 11; a mounting shell 23, hinged to the outer side wall of the upper mold 13; a limit block 24, Symmetrically arranged inside the mounting shell 23, and each of the limit blocks 24 is slidably connected to the inside of the mounting shell 23; spring 25, the outer wall of each limit block 24 is fixedly connected with a spring 25, and both ends of each spring 25 are respectively fixedly connected to the inside of the mounting shell 23 and the outer wall of the limit block 24; pull rod 26, the front surface of each limit block 24 is fixedly connected with a pull rod 26; the bottom of each limit block 24 is fixedly connected with a slider 4, and each slider 4 is slidably connected to the bottom surface of the inside of the mounting shell 23; each limit block 24 is trapezoidal in shape.

[0030] When ready for use, the operator places the lower mold 11 at the designated position, then pulls the handle 12 by hand to open the lower mold 11, then places the welding conductor into the placement hole 14, closes the lower mold 11, then places the welding powder into the reaction chamber in the lower mold 11, then closes the upper mold 13 and ignites the welding powder through the hole at the top of the upper mold 13. When the upper mold 13 needs to be replaced, the operator pulls the two pull rods 26 at the same time, and the pull rods 26 drive the limit block 24 on the same side to enter the interior of the installation shell 23, and then pulls upward. The upper mold 13 is moved, and the movement of the upper mold 13 drives the mounting shell 23 to move at the same time, so that the upper mold 13 is separated from the lower mold 11 and the disassembly is completed. When replacing a new upper mold 13, the operator pulls the pull rods 26 on both sides at the same time to drive the limit block 24 into the inside of the mounting shell 23, and the limit block 24 squeezes the spring 25. Then the operator moves the mounting shell 23 downward. When the mounting shell 23 contacts the fixing plate 21, the operator releases the two pull rods 26. Under the elastic force of the spring 25, the limit block 24 is ejected into the fixing buckle 22 , the mounting shell 23 is limited and fixed, so as to fix the upper mold 13, so as to complete the mold replacement, which improves the convenience of the operator; each limit block 24 is fixedly connected to the bottom with a slider 4, and the limit block 24 moves while driving the slider 4 to move at the same time. The slider 4 can limit the sliding direction of the limit block 24 to prevent the limit block 24 from being skewed under the elastic force of the spring 25, thereby causing the limit block 24 to be stuck in the mounting shell 23, and the operator is required to manually correct the direction, thereby improving the operator's work Efficiency; each limit block 24 is trapezoidal in shape, and when the mounting shell 23 moves downward, it drives the limit block 24 to squeeze the fixing buckle 22, and then continues to move the mounting shell 23 downward, so that the limit block 24 is squeezed into the mounting shell 23 and the compression spring 25 is squeezed at the same time. When the mounting shell 23 contacts the fixing plate 21, the limit block 24 is bounced into the fixing buckle 22 by the action of the spring 25 to complete the limiting fixation, so that the operator can complete the installation of the upper mold 13 without pulling the pull rod 26, thereby reducing the cumbersome operations during installation.

[0031] Embodiment 2

[0032] See also Figure 1-5 , based on the first embodiment, a linkage function is added;

[0033] A linkage assembly 3 is provided on the mounting shell 23, and the linkage assembly 3 includes: a shell 31, fixedly connected to the outer wall of the mounting shell 23; a rod body 32, inserted into the shell 31 and slidably connected to the shell 31; a rotating rod 33, one end of each of the pull rods 26 is hinged with a rotating rod 33, and each of the rotating rods 33 is hinged to one end of the rod body 32; a bolt 5 is threadedly connected to the top of the shell 31, and the bolt 5 is inserted into the rod body 32; one end of the rod body 32 is fixedly connected to a fixing block 6.

[0034] When disassembling the mold, the operator pulls the rod body 32 on the shell 31, and then the rod body 32 drives the rotating rod 33 to rotate. The rotation of the rotating rod 33 drives the two pull rods 26 to move to the opposite side at the same time, so that the two pull rods 26 drive the same-side limit blocks 24 to enter the installation shell 23 at the same time, thereby canceling the fixation of the limit blocks 24 on the upper mold 13, so that the upper mold 13 is separated from the lower mold 11, so that the operator can drive the limit blocks 24 on both sides to move at the same time without pulling the two pull rods 26 at the same time, thereby improving the convenience of the device; the top of the shell 31 is threadedly connected with a bolt 5. When After the upper mold 13 is replaced, the operator tightens the bolt 5 so that the bolt 5 rotates and moves toward the inside of the shell 31, and then inserts into the rod body 32, thereby further fixing the limit block 24 to prevent the operator from accidentally touching the limit block 24 when the device is in use, thereby causing the upper mold 13 to be unstable, thereby improving the stability of the device; a fixing block 6 is fixedly connected to one end of the rod body 32. When disassembling the upper mold 13, the operator can pull the fixing block 6 to drive the rod body 32 to move at the same time, preventing the rod body 32 from slipping due to its too smooth surface, thereby improving the safety of the device.
