[0024] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a refractory brick mold, including a mold body 1, a forming cavity 2 in the middle of the mold body 1, a butt plate 3 integrally formed on the surface of the mold body 1, and a replacement structure 4 in the interior of the mold body 1.

[0025] The refractory brick material is pushed into the molding cavity 2 by the equipment and then formed in the molding cavity 2.

[0026] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6 This utility model provides a refractory brick mold. The replacement structure 4 includes an installation frame 41. The installation frame 41 is assembled inside the mold body 1. The side of the installation frame 41 is provided with a slot 42. The front end of the installation frame 41 is welded with a positioning baffle 401. The forming cavity 2 is set in the installation frame 41.

[0027] A fixing block 43 is fixed to the outside of the mold body 1 by bolts. The fixing block 43 is equipped with a rotatably connected screw 44. The upper and lower ends of the screw 44 are equipped with sliders 45. The end face of the slider 45 is provided with a locking block 451. When the slider 45 slides to fit against the inside of the fixing block 43, the locking block 451 will insert into the fixing block 43, thereby improving the stability of the slider 45. The screw 44 is a positive and negative screw. The surface of the slider 45 is integrally formed with a push block 46. The surface of the push block 46 is provided with a positioning strip 461.

[0028] The mold body 1 is equipped with locking pins 47. The number of locking pins 47 is the same as that of the sliders 45.

The roller 471 contacts the surface of the push block 46, so that when the push block 46 moves along the surface of the locking pin 47, it is not easy for jamming to occur.

[0029] When the molding cavity 2 needs to be replaced, the screw 44 is rotated to make the slider 45 slide, and the push block 46 slides without pushing the retaining post 47. Under the action of the spring 410, the retaining post 47 will retract into the mold body 1. At this time, the retaining post 47 slides out of the retaining slot 42 and releases the restriction on the mounting frame 41. Then the mounting frame 41 can be directly removed to disassemble the molding cavity 2. The mounting frame 41 is installed into the mold body 1, and the positioning baffle 401 will fit against the surface of the mold body 1. At this time, the retaining slot 42 will be aligned with the retaining post 47. The screw 44 is rotated to make the slider 45 slide, and then the push block 46 pushes the retaining post 47, so that the retaining post 47 is inserted into the retaining slot 42. Then the mounting frame 41 is replaced, so as to achieve the beneficial effect of convenient replacement of the molding cavity 2.
