[0030] Further, as shown in Figure 5 , one end of the sleeve mold 22 is a semicircular protrusion 221, the other end of the sleeve mold 22 is provided with a groove 222, both ends of the groove 222 are round protrusions 223, and the two sides of the sleeve mold 22 are coaxial arc structures.

[0031] It should be noted that the shape of the inside of the sleeve mold 22 is the shape of the arc-shaped refractory brick to be processed.

[0032] Further, as shown in Figure 3 and Figure 4 , the outer wall of the sleeve mold 22 is attached to the inner wall of the cavity 211, the outer wall of the top plate 23 is attached to the inner wall of the sleeve mold 22, and the height of the sleeve mold 22 is greater than the height of the cavity 211.

[0033] It should be noted that the sleeve 22 and the cavity 211 are fitted, the top plate 23 and the sleeve 22 are fitted, that is, the inner side wall shape of the cavity 211 is consistent with the outer side wall shape of the sleeve 22, and the outer side wall shape of the top plate 23 is consistent with the inner side wall shape of the sleeve 22.

[0034] Further, as shown in Figure 3 and Figure 4 , the power component 24 includes a linear drive component one 241 fixedly installed at the bottom of the rack 1, and the output end of the linear drive component one 241 is fixedly connected with the bottom of the top plate 23, the bottom of the sleeve 22 is provided with a fixed lug 220, the fixed lug 220 is installed with a connecting plate 242, the rack 1 is fixedly installed with a linear drive component two 243, and the output end of the linear drive component two 243 is fixedly installed with the connecting plate 242.

[0035] It should be noted that the linear drive component one 241 and the linear drive component two 243 can both adopt air cylinders, the linear drive component one 241 is used to drive the vertical movement of the top plate 23 inside the sleeve 22, and the linear drive component two 243 drives the vertical movement of the sleeve 22 inside the cavity 211 through the connecting plate 242.

[0036] In this embodiment, the upper part of the mold assembly 2 is installed with a feeding assembly 3, when the feeding assembly 3 transports raw materials into the inside of the groove 222, the upper surface of the top plate 23 is flush with the upper surface of the mold body 21, and the sleeve 22 extends upward into the inside of the feeding assembly 3 to collect raw materials.

[0037] Further, as shown in Figure 6 , the feeding assembly 3 includes guide rails 31 arranged on both sides of the rack 1, a bottom plate 32 is arranged at the lower position between the two guide rails 31, one end of the bottom plate 32 is fitted with the mold body 21, and the upper surface of the bottom plate 32 coincides with the upper surface of the mold body 21, a moving frame 33 capable of sliding along the guide rails 31 is arranged between the two guide rails 31, a hopper 34 is installed on the moving frame 33, and the bottom of the hopper 34 is in contact with the upper surface of the bottom plate 32.

[0038] It should be noted that the bottom plate 32 is fixedly installed with the rack 1, the bottom plate 32 is fitted with the mold body 21, and the upper surface of the bottom plate 32 coincides with the upper surface of the mold body 21, that is, at the same height, so that when the moving frame 33 moves back and forth, the hopper 34 can smoothly slide on the upper surface of the mold body 21 and the bottom plate 32. The inside of the hopper 34 contains refractory brick raw materials, and the upper surfaces of the bottom plate 32 and the mold body 21 can block the raw materials so that the raw materials will not fall downward. Rollers 331 can be installed on both sides of the moving frame 33, the rollers 331 slide in the guide rails 31, and the rollers 331 can be driven to rotate by using a motor to realize the back and forth movement of the moving frame 33, or a cylinder can be used to directly drive the moving frame 33 to move.

[0039] In the embodiment, the top of the rack 1 is provided with a pressing assembly 5 for pressing the raw material in the sleeve mold 22 into shape.

[0040] Further, as shown in Figure 2 and Figure 8 , the pressing assembly 5 includes a linear drive component three 52 fixedly installed on the top of the rack 1, and the output end of the bottom of the linear drive component three 52 is fixedly installed with a stabilizing frame 51, and the bottom of the stabilizing frame 51 is installed with an upper mold 53, and the linear drive component three 52 is used to drive the upper mold 53 into the inside of the sleeve mold 22 to press the raw material into shape.

[0041] It should be noted that the linear drive component three 52 can use a hydraulic cylinder to drive the stabilizing frame 51 and the upper mold 53 to move downward, and the upper mold 53 extends into the inside of the sleeve mold 22, thereby realizing the pressing and molding of the refractory bricks.

[0042] Further, the rack 1 is vertically installed with a guide rod 11 on both sides, and the two ends of the stabilizing frame 51 are movably sleeved on the guide rod 11 and can move vertically along the guide rod 11.

[0043] It should be noted that the guide rod 11 can improve the stability of the vertical movement of the stabilizing frame 51.

[0044] In the embodiment, the implementation is specifically as follows: Figure 4 As shown in the cavity 211, one end close to the mold body 21 has two smaller areas, which correspond to the semicircular protrusions 221 on the sleeve mold 22. If the raw material is directly dropped from top to bottom into the inside of the cavity 211, due to the small space of the two smaller areas and the extrusion between the raw materials, there will be a problem of insufficient material falling in this area. Therefore, the mold assembly 2 is designed.

[0045] In the initial state, the moving frame 33 and the hopper 34 are not located directly above the mold assembly 2, but are located in a rear position directly above the mold assembly 2. A spiral conveyor can be arranged at the rear position of the rack 1 to convey the refractory brick raw materials to the inside of the hopper 34. The upper end surface of the sleeve mold 22 and the top plate 23 are flush with the upper end surface of the mold body 21. In operation, first, the moving frame 33 moves along the guide rail 31 to be directly above the mold body 21, so that the sleeve mold 22 and the top plate 23 are directly below the power component 24. Then, the sleeve mold 22 is driven upward by the linear driving component two 243, the sleeve mold 22 is inserted into the inside of the hopper 34, the raw materials in the inside of the hopper 34 enter the inside of the sleeve mold 22, and then the sleeve mold 22 is driven downward by the linear driving component two 243, and at the same time, the top plate 23 is driven downward by the linear driving component one 241. The sleeve mold 22 and the top plate 23 move downward at the same speed until the upper surface of the sleeve mold 22 is flush with the upper surface of the mold body 21. At this time, the feeding is completed. Since the sleeve mold 22 is inserted upward into the inside of the hopper 34 to take the raw materials, the raw materials can directly enter the inside of the sleeve mold 22 vertically during the insertion, so that even the small area of the round corner protrusion 223 can be normally filled with the raw materials. Secondly, the moving frame 33 moves back to the initial position along the guide rail 31. Thirdly, the stable frame 51 and the upper mold 53 are vertically moved by the linear driving component three 52, the upper mold 53 enters the inside of the sleeve mold 22, the raw materials in the sleeve mold 22 are pressed to form the refractory brick. Finally, the top plate 23 is driven upward by the linear driving component one 241 to a position where the upper surface of the top plate 23 is flush with the upper surface of the mold body 21, so that the top plate 23 pushes the refractory brick in the sleeve mold 22 upward to achieve the purpose of discharging. It should be noted that the state of the sleeve mold 22 and the top plate 23 at this time is exactly the state in which the feeding assembly 3 can be moved directly above the mold assembly 2, so that the refractory brick production process is continuous and compact.

[0046] The above technical solution sets the sleeve mold 22 in the inside of the cavity 211, and adopts the mode of inserting the sleeve mold 22 upward into the inside of the hopper 34 to take the raw materials, so that the raw materials can directly enter the inside of the sleeve mold 22 vertically during the insertion, even the small area of the round corner protrusion 223 can be normally filled with the raw materials, avoiding the problem of insufficient material falling in this area, and ensuring the compactness after pressing and the quality of the fired refractory brick.

[0047] Referring to the drawings accompanying the specification Figures 6-7 The side wall of the sleeve mold 22 has a certain thickness. When the sleeve mold 22 is inserted upward into the inside of the hopper 34, the top of the sleeve mold 22 will hold or accumulate a part of the raw materials. The raw materials are extruded, so that the speed of the raw materials entering the round corner protrusion 223 area slows down. The sleeve mold 22 needs to move up and down repeatedly for a small distance many times, which leads to a slow feeding speed. Therefore, the following technical solution is further proposed.

[0048] Specifically, as shown in Figure 6 and Figure 7 , the upper end of the hopper 34 is fixedly installed with a mounting frame 35, the mounting frame 35 is installed with a auxiliary feeding component 36 corresponding to the sleeve mold 22, the auxiliary feeding component 36 includes a feeding ring 364 and an elastic telescopic structure for driving the feeding ring 364 to reset downward, the bottom surface profile of the feeding ring 364 is the same as the profile of the upper surface of the sleeve mold 22, and the upper end of the feeding ring 364 is provided with an inclined surface 365 in the circumferential direction, so that the upper end of the cross section of the feeding ring 364 is pointed.

[0049] It should be noted that when the feeding assembly 3 moves to the top of the mold assembly 2, the bottom surface of the feeding ring 364 is in contact with the upper surface of the sleeve mold 22, and when the sleeve mold 22 is inserted into the inside of the hopper 34 upward, the sleeve mold 22 will push the feeding ring 364 upward, and since the upper end of the inclined surface 365 is a pointed end, the inclined surface 365 will pierce the raw materials inside the hopper 34 upward, and the raw materials will not accumulate at the upper end of the feeding ring 364, but will directly fall into the inside of the sleeve mold 22, so that only one upward movement of the sleeve mold 22 is needed to fill the raw materials into the inside of the sleeve mold 22.

[0050] Further, as shown in Figure 7 , the elastic telescopic structure includes a fixed rod 361 fixedly installed on the mounting frame 35, the fixed rod 361 is vertically and slidingly installed with a movable frame 362, the movable frame 362 is fixedly connected with the feeding ring 364, and the outer side of the fixed rod 361 is sleeved with a spring 363, and the both ends of the spring 363 are pressed on the movable frame 362 and the mounting frame 35.

[0051] It should be noted that when the sleeve mold 22 moves to the highest point, the feeding is completed, and then the sleeve mold 22 moves downward, and since the feeding ring 364 is pressed on the upper end of the sleeve mold 22, there is no blockage of raw materials directly below, so it can move downward together with the sleeve mold 22 under the action of the spring 363 until the upper end of the sleeve mold 22 is flush with the upper surface of the mold body 21.

[0052] Referring to the drawings accompanying the specification Figure 1 , the front end of the moving frame 33 is fixedly installed with a pushing plate 4, and the front end of the rack 1 is installed with a conveying belt 6, and the pushing plate 4 is used to push the firebricks to the conveying belt 6.

[0053] It should be noted that during the movement of the feeding assembly 3 to the top of the mold assembly 2, the pushing plate 4 can push the firebricks pushed upward by the top plate 23 to the conveying belt 6, and the conveying belt 6 conveys the firebricks away for stacking by the staff.

[0054] Working principle: in the initial state, the moving frame 33 and the hopper 34 are located at the rear side position above the mold assembly 2, and the upper end surfaces of the sleeve mold 22 and the top plate 23 are flush with the upper end surface of the mold body 21.

[0055] In operation, the following steps are taken:

[0056] Step one: the moving frame 33 moves along the guide rail 31 to the top of the mold body 21, so that the sleeve mold 22 and the top plate 23 are directly below the hopper 34.

[0057] Step two: the sleeve mold 22 is driven upward by the linear drive component two 243, which pushes the feeding ring 364 upward, compresses the spring 363, and makes the inclined surface 365 pierce the raw material inside the hopper 34 upward, so that the raw material falls into the sleeve mold 22. After the sleeve mold 22 moves to the highest point, it moves downward, and at the same time, the top plate 23 is driven downward by the linear drive component one 241. The sleeve mold 22 and the top plate 23 move at the same speed, and the feeding ring 364 moves downward with the sleeve mold 22 under the action of the spring 363, until the upper end of the sleeve mold 22 is flush with the upper surface of the mold body 21. At this time, the feeding is completed.

[0058] Step three: the moving frame 33 moves back along the guide rail 31 to the initial position.

[0059] Step four: the stable frame 51 and the upper mold 53 are vertically moved by the linear drive component three 52, and the upper mold 53 enters the inside of the sleeve mold 22 to press and form the raw material in the sleeve mold 22 into refractory bricks.

[0060] Step five: the top plate 23 is driven upward by the linear drive component one 241 to a position where the upper surface of the top plate 23 is flush with the upper surface of the mold body 21, so that the top plate 23 pushes the refractory bricks in the sleeve mold 22 upward to achieve the purpose of discharging.

[0061] It should be noted that in step one, during the movement of the moving frame 33 along the guide rail 31 to the top of the mold body 21, the refractory bricks pushed out by the top plate 23 in step five can be pushed onto the conveyor belt 6 by the pushing plate 4, and the conveyor belt 6 can convey the refractory bricks away for stacking by the staff.

[0062] Finally, the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
