After pressing, the rotation of the tilting motor allows for rapid transfer of multiple brick blanks.

[0004] The mold for producing hydrate-resistant magnesia-calcium bricks described above has a shaping device formed by welding vertical and horizontal plates to create a fixed separation. During the extrusion process, the raw material is subjected to high pressure and is prone to leakage from the gap between the plates, which can easily lead to deformation of the magnesia-calcium bricks after demolding.

[0006] The technical solution of this utility model is as follows: A magnesia-calcium brick processing mold includes a workbench, a lower mold base is fixedly connected to the lower front of the workbench, a mold sleeve assembly is placed inside the lower mold base, the mold sleeve assembly includes a mold sleeve plate, the top of the mold sleeve plate has mold cavities for placing magnesia-calcium brick raw materials through at equal intervals, a first sealing ring is fixedly connected to the outer side of the bottom of each mold cavity to prevent the magnesia-calcium brick raw material from leaking out, the top of the lower mold base is symmetrically provided with positioning components that can press the mold sleeve plate downwards, the bottom of the lower mold base is provided with an ejection component that can lift the mold sleeve plate upwards after the magnesia-calcium brick is formed, and the upper front of the workbench is provided with a pressing component for pressing the magnesia-calcium brick raw material in the mold cavity.

[0007] Preferably, the bottom of the lower mold base is symmetrically provided with bottom grooves, and the inner wall of the lower mold base is symmetrically provided with track grooves.

[0008] Preferably, the mold assembly further includes a slide block, which is symmetrically and fixedly connected to the outside of the mold plate.

[0009] Preferably, the positioning component includes a first hydraulic cylinder, which is fixedly installed on the top of the lower mold base, and a pressure plate is fixedly connected to the telescopic end of the first hydraulic cylinder.

[0010] Preferably, the molding assembly includes a second hydraulic cylinder, which is fixedly installed on the front of the worktable.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model has a mold sleeve plate placed inside the lower mold base. After the magnesia-calcium brick raw material is filled into the mold cavity, the first hydraulic cylinder can be activated first to drive the pressure plate to press down the mold cavity, thereby pressing the first sealing ring at the bottom of the mold sleeve plate outside the mold cavity onto the bottom of the lower mold base. When the second hydraulic cylinder drives the upper module to press down the magnesia-calcium brick raw material in the mold cavity, the second sealing ring will also be pressed down on the top of the mold sleeve plate outside the mold cavity. Compared with the prior art, this design can avoid the side leakage of the high-temperature magnesia-calcium brick raw material at the bottom of the lower mold base and the gap between the mold sleeve plate due to pressure during the molding process.

[0016] 2. This utility model has an ejection assembly at the bottom of the lower mold base. After the molding assembly completes the molding of the magnesium-calcium brick raw material in the mold cavity, the first hydraulic cylinder can be started to drive the pressure plate to rise and separate from the mold sleeve plate. Then, the telescopic end of the third hydraulic cylinder is started to drive the toothed plate to move horizontally. Under the meshing cooperation of the toothed plate and the toothed column, the connecting rod drives the elliptical plate to rotate at the bottom groove. This design allows the elliptical plate to push off the mold sleeve plate. Since the magnesium-calcium brick raw material is still pressed by the upper module, the mold sleeve plate can move upward under the influence of the elliptical plate. This design allows the mold sleeve plate and the molded magnesium-calcium brick raw material to be quickly separated. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] Please see Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 This utility model provides a technical solution: a magnesium-calcium brick processing mold, including a workbench 1, a lower mold base 11 fixedly connected to the lower part of the front of the workbench 1, a mold sleeve assembly 2 placed inside the lower mold base 11, the mold sleeve assembly 2 including a mold sleeve plate 21, the top of the mold sleeve plate 21 is provided with mold cavities 22 for placing magnesium-calcium brick raw materials through at equal intervals, a first sealing ring 221 for preventing side leakage of magnesium-calcium brick raw materials is fixedly connected to the outer side of the bottom of each mold cavity 22, a positioning assembly 3 that can press the mold sleeve plate 21 downward is symmetrically arranged on the top of the lower mold base 11, an ejection assembly 5 that can push the mold sleeve plate 21 upward after the magnesium-calcium brick is formed is arranged at the bottom of the lower mold base 11, and a pressing assembly 4 for pressing the magnesium-calcium brick raw materials in the mold cavity 22 is arranged on the upper part of the front of the workbench 1;

[0026] This design solves the problem that in existing technologies, raw materials are easily leaked from the gaps between the plates under high pressure during the extrusion process, which can easily lead to deformation of magnesium-calcium bricks after demolding.

[0027] Please see Figure 3 The bottom of the lower mold base 11 is symmetrically provided with a bottom groove 12, and the inner wall of the lower mold base 11 is symmetrically provided with a track groove 13.

[0028] Please see Figure 2 The mold assembly 2 also includes a slide 23, which is symmetrically and fixedly connected to the outside of the mold plate 21. Rollers 231 are rotatably connected to the outside of the slide 23 at equal intervals. The positions of the rollers 231, the slide 23, and the rail groove 13 correspond.

[0029] This design allows the mold plate 21 to slide smoothly upward along the inner side of the lower mold base 11 when it is pushed up by the elliptical plate 532.

[0030] Please see Figure 3 The positioning component 3 includes a first hydraulic cylinder 31, which is fixedly installed on the top of the lower mold base 11, and a pressure plate 32 is fixedly connected to the telescopic end of the first hydraulic cylinder 31.

[0031] The first hydraulic cylinder 31, in conjunction with the pressure plate 32, can perform the clamping work during the molding process and the loosening work after the molding is completed on the mold sleeve plate 21.

[0032] Please see Figure 4 The molding assembly 4 includes a second hydraulic cylinder 41, which is fixedly installed on the front of the workbench 1. The extension end of the second hydraulic cylinder 41 is fixedly connected to an upper module 42. Each upper module 42 corresponds to the position of each mold cavity 22. A second sealing ring 421 is fixedly connected to the bottom of the outer side of each upper module 42.

[0033] The pressing of the magnesium-calcium brick raw material in the mold cavity 22 can be completed by driving the upper module 42 to press down through the second hydraulic cylinder 41. At the same time, the second sealing ring 421 can effectively prevent the high-temperature magnesium-calcium brick raw material from flowing out from the gap between the upper module 42 and the mold cavity 22 due to pressure.

[0034] Please see Figure 5 The ejection assembly 5 includes a limiting support 54, which is fixedly connected to the bottom of the lower mold base 11. A connecting rod 53 is rotatably connected to the middle of the limiting support 54, and elliptical plates 532 are symmetrically fixedly connected to the outer side of the connecting rod 53. Each elliptical plate 532 corresponds to the position of each bottom groove 12.

[0035] Ejection assembly 5 also includes mounting sleeve 51, which is fixedly connected to the side of lower mold base 11. A third hydraulic cylinder 52 is installed inside the mounting sleeve 51, and a toothed plate 521 is fixedly connected to the telescopic end of the third hydraulic cylinder 52.

[0036] The ejection assembly 5 also includes a toothed column 531, which is fixedly connected to one end of the connecting rod 53. The toothed column 531 is in contact with the toothed plate 521 and is in a meshing transmission connection.

[0037] By activating the third hydraulic cylinder 52 and cooperating with the toothed plate 521 and toothed column 531, the connecting rod 53 drives the elliptical plate 532 to rotate, thereby pushing the mold sleeve plate 21 in the lower mold base 11 upward after the magnesium calcium brick has completed cooling and molding, until the mold sleeve plate 21 is separated from the magnesium calcium brick.

[0038] The working principle and usage process of this utility model are as follows:

[0039] First, the workers place the mold plate 21 inside the lower mold base 11. Then, the first hydraulic cylinder 31 is activated to drive the pressure plate 32 to press down the mold plate 21, so that the first sealing ring 221, located outside the mold cavity 22, is tightly attached to the bottom of the inner wall of the lower mold base 11. Then, the magnesium calcium brick raw material is put into the mold cavity 22, and the second hydraulic cylinder 41 is activated to drive the upper module 42 to press down to complete the molding work of the magnesium calcium brick in the mold cavity 22.

[0040] After the magnesia-calcium bricks are cooled and formed in the mold cavity 22, the first hydraulic cylinder 31 can be activated to move the pressure plate 32 upward, so that the pressure plate 32 is separated from the mold sleeve plate 21. At this time, the telescopic end of the third hydraulic cylinder 52 is activated to drive the toothed plate 521 to advance horizontally. Under the meshing cooperation of the toothed plate 521 and the toothed column 531, the connecting rod 53 drives the elliptical plate 532 to rotate at the bottom groove 12. Through this design, the elliptical plate 532 can push the mold sleeve plate 21. Since the magnesia-calcium brick raw material is still pressed by the upper module 42, the mold sleeve plate 21 can be moved upward by the influence of the elliptical plate 532. Through this design, the mold sleeve plate 21 and the formed magnesia-calcium brick raw material can be quickly separated.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
