[0022] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings.

[0023] The utility model provides a casting and forming mold for testing refractory bricks:

[0024] like Figure 2 As shown in or 3, side panel 1 and side panel 2 are arranged parallel to each other in front and back, and fixing holes 5 are provided on the left and right sides of side panel 1 and side panel 2, and limiting grooves 7 are provided at the inner end positions of side panel 1 and side panel 2, and the limiting grooves 7 are located on the inner side positions of the fixing holes 5; the front and rear ends of blocking plate 1 3 are installed in the limiting grooves 7 on the left side of side panel 1 and side panel 2, and the front and rear ends of blocking plate 2 4 are installed in the limiting grooves 7 on the right side of side panel 1 and side panel 2.

[0025] The above-mentioned fixing holes 5 are opened on the left and right sides of the side plate 1 and the side plate 2, the main purpose of which is to provide a fixing position for the installation of the screw, so as to facilitate the tightening and fixing of the screw and the nut.

[0026] The aforementioned limiting grooves 7 are provided at the inner ends of side panels 1 and 2. Their primary purpose is to provide space for the installation and positioning of blocking panels 1 and 2, thereby providing the necessary conditions for the integral fastening of side panels 1, 2, 1, 2, and 8 to the bottom plate. The position of the limiting grooves 7 can be specifically determined based on the requirements for the refractory brick process size.

[0027] like Figure 2As shown in or 4, the bottom plate 8 is installed at the bottom of the square cavity surrounded by the side plate 1, the side plate 2, the blocking plate 3, and the blocking plate 2; the bottom plate 8 is formed by horizontally connecting the bottom plate 1 81, the bottom plate 2 82, the bottom plate 3 83, the bottom plate 4 84 and the bottom plate 5 85 in sequence; the edges of the connecting surfaces of the bottom plate 1 81 and the bottom plate 2 82 are symmetrical on the left and right, and a half-cone-shaped groove is vertically opened, and the edges of the connecting surfaces of the bottom plate 4 84 and the bottom plate 5 85 are symmetrical on the left and right, and a half-cone-shaped groove is vertically opened; the half-cone-shaped grooves set on the connecting surfaces of the bottom plate 1 81, the bottom plate 2 82, the bottom plate 4 84, and the bottom plate 5 85 are connected to form a support column forming cavity 6.

[0028] The bottom plate 1 81 , bottom plate 2 82 , bottom plate 3 83 , bottom plate 4 84 and bottom plate 5 85 are horizontally butted in sequence, which facilitates the rapid disassembly of the bottom plate 8 when the refractory bricks for the sample test are demoulded after being cast and formed.

[0029] The edges of the docking surfaces of the above-mentioned bottom plate 1 81 and bottom plate 2 82 are symmetrical on the left and right, and a half-cone-shaped groove is vertically opened. The edges of the docking surfaces of the above-mentioned bottom plate 4 84 and bottom plate 5 85 are symmetrical on the left and right, and a half-cone-shaped groove is vertically opened. The half-cone-shaped grooves set on the docking surfaces of the bottom plate 1 81, bottom plate 2 82, bottom plate 4 84, and bottom plate 5 85 are docked to form a support column forming cavity 6. Its main purpose is to use the docked support column forming cavity 6 to cast and form the support column 2 at the bottom of the test refractory brick body 1. At the same time, since the bottom plate 8 is set to a detachable docking structure, the cast support column will not be damaged when the support column 2 falls off, thereby improving the casting quality of the test refractory brick body 1 and the support column 2.

[0030] like Figure 3 As shown, the square cavity enclosed by side plate 1, side plate 2, blocking plate 1, and blocking plate 2 is formed. This square cavity is the casting and molding cavity for the test refractory bricks. In conjunction with the detachable bottom plate 8, the test refractory brick body 1 and support column 2 can be smoothly demolded after the test refractory bricks are cast and molded, effectively preventing damage to the molded support column 2 due to the unsmooth removal of the support column 2.

[0031] like Figure 2 、 3 As shown, the limiting groove 7 is a concave square shape, extending from bottom to top through the bodies of side panel 1 and side panel 2. The width of the limiting groove 7 is greater than the thickness of blocking panel 1 3 and blocking panel 2 4, and the height of the limiting groove 7 is greater than the height of blocking panel 1 3 and blocking panel 2 4. The purpose of this arrangement is to improve the fitting accuracy of side panel 1 1, side panel 2 2, blocking panel 1 3, and blocking panel 2 4 during assembly.

[0032] like Figure 3 、 4As shown, bottom plate 8 is smaller than the square cavity enclosed by side plate 1, side plate 2, plugging plate 1, and plugging plate 2. This arrangement facilitates the smooth installation of bottom plate 8, which is formed by horizontally connecting bottom plate 1, bottom plate 2, bottom plate 3, bottom plate 4, and bottom plate 5, within the square cavity enclosed by side plate 1, side plate 2, plugging plate 1, and plugging plate 2. This improves the precision of the mold used to test refractory bricks.

[0033] like Figure 1-4 As shown in the figure, the assembly, casting and demoulding process of the casting and molding mold for testing refractory bricks in this test is as follows:

[0034] 1. Test the assembly of the casting and molding mold for refractory bricks: first, place the side plate 1 and the side plate 2 2 in parallel on the vibration platform used for casting and molding, and then install the blocking plate 3 and the blocking plate 2 4 into the limiting grooves 7 opened on the inner sides of the side plate 1 and the side plate 2 2 respectively to form a square cavity; then, the bottom plate 1 81, the bottom plate 2 82, the bottom plate 3 83, the bottom plate 4 84 and the bottom plate 5 85 are horizontally connected in sequence in the square cavity surrounded by the side plate 1, the side plate 2, the blocking plate 1 3 and the blocking plate 2 4 to form the bottom plate 8; finally, use a screw to pass through the corresponding front and rear fixing holes 5 at both ends of the side plate 1 and the side plate 2, and tighten the nut on the screw to fix the side plate 1, the side plate 2, the blocking plate 1 3, the blocking plate 2 4 and the bottom plate 8 as one.

[0035] 2. Casting and demolding of test refractory bricks: first, contact the bottom surface of the bottom plate 8 with the vibration table, and place the casting and molding mold of the test refractory bricks on the vibration table for standby; then pour the test refractory brick casting and molding raw materials that have been well proportioned and stirred evenly into the square cavity surrounded by side plate 1, side plate 2, blocking plate 1 3, blocking plate 2 4 and bottom plate 8, and use a vibrating rod to vibrate and exhaust. After the test refractory bricks are cast and formed, remove the screws and nuts in the fixing holes 5, and then remove the side plates 1 1, side plate 2 2, blocking plate 1 3, blocking plate 2 4. To remove the bottom plate 8, first push out the bottom plate 3 83 horizontally (the inclined surface structure of the upper and lower sides of the bottom plate 3 83 can be used to smoothly remove the bottom plate 3 83), and finally remove the bottom plate 1 81, bottom plate 2 82, bottom plate 4 84 and bottom plate 5 85 one by one to achieve the demolding of the test refractory bricks after casting and molding.
