[0018] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0019] As shown in the figure, a mold for making coke oven corbel refractory bricks includes a bottom plate 1, two side plates 2 and two end plates 3. During actual operation, the bottom plate 1, the side plates 2 and the end plates 3 are all placed in a rectangular mold cavity, the bottom plate 1 is located at the bottom of the mold cavity, the outer side surfaces of the side plates 2 and the end portions are both close to the inner wall of the mold cavity, and at the bottom of the mold cavity, the side plates 2 and the end portions are located around the bottom plate 1 to avoid tilting of the side plates 2 and the end plates 3.

[0020] The side plates 2 and the end plates 3 are respectively arranged around the bottom plate 1. The edge of one side of the upper surface of the bottom plate 1 has a downwardly recessed step groove 101, which is used to correspond to the boss 601 below the brick 6 to facilitate the molding of the boss 601. The cavity surrounded by the side plates 2 and the end plates 3 is provided with a top plate 5 that can be vertically lifted and lowered. After the refractory material is filled in the cavity, the top plate 5 moves downward under the action of the brick press, thereby compacting the refractory material. The cavity surrounded by the side plates 2 and the end plates 3 is provided with a mold core 4 with an inclined middle part. The two ends of the mold core 4 are respectively placed at the through holes opened in the middle of the top plate 5 and the bottom plate 1. The mold core 4 is used to facilitate the molding of the inclined hole 603 in the middle of the brick 6.

[0021] The mold core 4 includes a cylindrical section 401 located at the upper and lower ends, and an inclined section 402 detachably connected to the cylindrical section 401. The center line of the inclined section 402 is set at an angle to the upper and lower surfaces respectively. This setting is for the convenience of installing the mold core 4 on the base plate 1 and for the convenience of rapid demolding of the brick blank 6 after forming.

[0022] During specific use, at the assembly stage, the cylindrical sections 401 at both ends are respectively installed at the end positions of the inclined section 402 to form the entire core mold 4, and then the lower cylindrical section 401 is correspondingly inserted into the through hole on the bottom plate 1. After the upper cylindrical section 401 is adjusted to a good position and filled with refractory material, the top plate 5 is installed. At this time, the upper cylindrical section 401 can slide in the through hole of the top plate 5; during disassembly (that is, after the brick blank 6 is formed), the top plate 5 is disassembled first, and then the upper and lower cylindrical sections 401 are removed from the inclined section 402, thereby facilitating the inclined section 402 to be pulled out from the core mold 4 and completing the forming of the brick blank 6.

[0023] The cylindrical section 401 has a protruding screw 403 at its end, which is connected to the inclined section 402 by threaded connection, that is, there are threaded holes in the middle of both ends of the inclined section 402 to facilitate the rapid installation of the cylindrical section 401 on the inclined section 402.

[0024] The top plate 5 is slidably matched with the cylindrical section 401 located above the mold core 4, so that the top plate 5 moves up and down, thereby compacting the refractory material.

[0025] The lower surface of the top plate 5 has a concave countersunk portion 501 , and the edge of the countersunk portion 501 is rounded. The countersunk portion 501 and the rounded corners are provided to facilitate the formation of the truncated table 602 above the brick blank 6 .

[0026] When the mold for making this coke oven bull leg refractory brick is in use, the bottom plate 1, two side plates 2 and two end plates 3 are placed in the mold cavity, the assembled core 4 is inserted into the through hole position on the bottom plate 1, and then filling is carried out. After the filling is completed, the top plate 5 is placed in the cavity formed by the side plates 2 and the end plates 3. At this time, the cylindrical section 401 at the upper end of the core 4 is inserted into the circular hole of the top plate 5, and the length of the top plate 5 matches the spacing between the two side plates 2, and the width of the top plate 5 matches the spacing between the two end plates 3, so that the top plate 5 only has the freedom to move up and down. After the brick press is started, the top plate 5 moves up and down to compact the refractory material in the cavity, thereby completing the molding of the brick blank 6.
