DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings 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.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] like Figures 1 to 4 As shown, a cathode carbon block center seam filling mold is provided on the cathode carbon block, and two groups of parallel steel bar assemblies are provided on the cathode carbon block, and each group of steel bar assemblies includes two steel bars arranged along the same horizontal line and set at a fixed distance. Specifically, two horizontal slots 11 are provided on the cathode carbon block 1, and two groups of parallel steel bar assemblies are provided in the two slots 11, and each group of steel bar assemblies includes two steel bars 2 arranged along the same horizontal line and set at a fixed distance in the slots 11, and there is a filling cavity 21 between the two steel bars 2, that is, the two steel bars 2 located in the same slot 11 do not contact each other and have a gap. When producing the cathode carbon block 1 of this structure, it is necessary to fill the center seam of the cathode carbon block 1, that is, the filling cavity 21 between the two steel bars 2 with steel bar paste 22, and then a pouring layer 23 is provided on both sides of the steel bar paste 22 and the upper end surface of the cathode carbon block 1. The mold of the utility model is used to fill and form the pouring layer 23.

[0036] like Figures 5 to 9 As shown, a cathode carbon block pouring layer mold comprises a first template 3 and a second template 4. The bottom end of the first template 3 is provided with two limiting grooves 31 at a fixed distance. The shape, size, etc. of the limiting grooves 31 are the same as those of the steel rod 2. The upper end of the first template 3 is provided with two mounting grooves 32 at a fixed distance. The mounting grooves 32 are respectively arranged on both sides of the first template 3. Two first templates 3 are provided. The limiting grooves 31 of the first template 3 are respectively matched with the corresponding steel rods 2, that is, the first template 3 is closely arranged with the steel rod 2 through the limiting grooves 31. The side walls of the first template 3 are respectively closely arranged with the ends of the cathode carbon block 1. Two second templates 4 are provided. The two ends of the second template 4 are respectively arranged in the mounting grooves 32 of the two first templates 3, and the second template is closely arranged with the side walls of the cathode carbon block 1, so that the first side mold and the second side mold surround the filling cavity 21.

[0037] The mold is easy to assemble and is used to fill the upper surface of the cathode carbon block 1 to form a pouring layer 23, which can quickly assist workers to complete the pouring of the upper part of the cathode carbon block 1, further improving the assembly efficiency of the cathode carbon block 1 and the steel rod 2.

[0038] As a preferred embodiment of the present invention, the width of the mounting groove 32 is the same as the width of the second template 4, and the width of the limiting groove 31 is denoted as d, so that the second template 4 can be snapped into the mounting groove 32 of the first template 3 without the need for other connecting parts to fix it.

[0039] As another preferred embodiment of the present invention, the width of the installation groove 32 is greater than the width of the second template 4, and the width of the limiting groove 31 is recorded as d. This design allows the second template 4 to be slidably adjusted to a certain distance after being set in the installation groove 32, ensuring that the second template 4 can be closely attached to the outer wall of the cathode carbon block 1. This design facilitates the adjustment of the relative position between the second template 4 and the cathode carbon block 1, ensuring that there is no gap between the cathode carbon block 1 and the second template 4, and preventing the casting material from leaking out during casting.

[0040] Example 2

[0041] like Figures 10 to 14 As shown, further, a T-shaped connecting plate 34 is provided at an upper end of one side of the first template 3, and a plurality of threaded holes 35 are provided on the connecting plate 34, and tightening screws (not shown in the figure) are threadedly connected in the threaded holes 35.

[0042] After the second template 4 is installed in the installation groove 32 of the first template 3, the second template 4 is tightened by the tightening screw to achieve a stable fixed connection between the second template 4 and the first template 3. This structure is applicable to the two situations in Example 1, that is, the width of the installation groove 32 is the same as the width of the second template 4, or the width of the installation groove 32 is greater than the width of the second template 4.

[0043] Furthermore, a fixing plate 33 is respectively extended on the first template 3 on one side of the two limiting grooves 31. The shape of the fixing plate 33 is consistent with the shape of the limiting grooves 31, and the fixing plate 33 is set close to the outer wall of the steel rod 2. Such a design can ensure that the first template 3 can be stably supported on the cathode carbon block 1 and the steel rod 2 without the need to use manpower or other mechanisms to maintain it. After the first template 3 is stably supported, it will not fall over, and the second template 4 can be quickly installed. Even one person can complete the installation operation of the mold. Of course, in addition to the above situation, the structure of the fixing plate 33 can also be set as a square frame, and slidably set on the outer wall of the steel rod 2 to achieve stable support of the first template 3.

[0044] Furthermore, the upper surface of the cathode carbon block 1 between the two steel bars 2 is filled with steel bar paste 22, and a U-shaped tie rod 5 is arranged above the steel bar paste 22, and the two ends of the tie rod 5 are respectively arranged close to the side wall of the second template 4. Through the design of the tie rod 5, the fixing effect between the two second templates 4 can be further strengthened to avoid the gap between the middle of the second template 4 and the cathode carbon block 1 due to the excessive length of the cathode carbon block 1, or the gap caused by squeezing during pouring. The tie rod 5 is arranged on the steel bar paste 22. During pouring, since the steel bar paste 22 has been poured in advance, the presence of the tie rod 5 will not affect the pouring of the pouring layer 23.

[0045] Example 3

[0046] In this embodiment, the first template 3 can also be used to replace the pull rod 5.

[0047] On the premise that the width of the mounting groove 32 is the same as the width of the second template 4 , the upper surface of the cathode carbon block 1 between the two steel bars 2 is filled with steel bar paste 22 , and the first template 3 is arranged above the steel bar paste 22 .

[0048] like Fig.15 As shown, the first template 3 is provided with ribs 321 on both sides, the height of the ribs 321 higher than the first template 3 is denoted as h, and the width of the limit groove 31 is denoted as d. The ribs 321 of the first template 3 are respectively arranged close to the side walls of the second template 4. That is, the first template 3 is inverted, the upper end surface of the first template 3 is arranged above the steel rod paste 22, and then the ribs 321 are extended downward, and the ribs 321 are clamped on the side walls of the second template 4 on both sides to achieve the connection and fixation between the two second templates 4. With this structure, the first template 3 can be installed upright on both sides of the cathode carbon block 1, or it can be installed upside down in the middle of the cathode carbon block 1 to achieve more functions.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
