[0017] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0018] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and describe this application in detail in conjunction with the embodiments.

[0019] Embodiment 1, see Figures 1 - 9 , this embodiment provides a die-casting device for refractory production, including a bottom plate 100 and a top plate 200. The bottom plate 100 and the top plate 200 are connected by four support columns 300. A fixed die 400 is fixed on the top of the bottom plate 100. An electric push rod 600 is fixed on the top end of the top plate 200. A moving die 500 is fixed on the extension rod of the electric push rod 600. The moving die 500 penetrates and is slidably connected to the four support columns 300; A loop-shaped track 700 is fixed on the outer side of the stationary mold 400. A vibration assembly 800 is assembled on the loop-shaped track 700. The vibration assembly 800 includes a first slider 810 and a second slider 820. The first slider 810 and the second slider 820 are hinged by an elastic hinge 830. Both the first slider 810 and the second slider 820 are slidably connected to the loop-shaped track 700. A driving assembly 840 is embedded in the first slider 810. The driving assembly 840 is composed of a driving motor and a moving wheel, wherein the moving wheel is in contact with the surface of the loop-shaped track 700. First shock assemblies 850 are assembled at both the top and the bottom of the first slider 810. The first shock assembly 850 includes a first support rod 851 fixed on the first slider 810. A first rotating rod 852 is rotatably connected to the side of the first support rod 851 away from the first slider 810. A first friction wheel 854 is fixed to the bottom of the first rotating rod 852. A plurality of first elastic knocking rods 853 are arranged in an annular array on the outer side of the first rotating rod 852. Second shock assemblies 860 are assembled at both the top and the bottom of the first slider 810. The second shock assembly 860 includes a second support rod 861 fixed on the second slider 820 and a third support rod 862 fixed on the second slider 820. A first bevel gear 863 is rotatably connected to the side of the second support rod 861 away from the second slider 820. A second rotating rod 864 is fixed to the bottom of the first bevel gear 863. A second friction wheel 866 is fixed to the bottom of the second rotating rod 864. A plurality of second elastic knocking rods 865 are arranged in an annular array on the outer side of the second rotating rod 864. A third rotating rod 867 passes through and is rotatably connected in the third support rod 862. A second bevel gear 868 meshing with the first bevel gear 863 is fixed to one end of the third rotating rod 867. A runner 869 is fixed to the other end of the third rotating rod 867. A plurality of vertical vibration rods 8610 are hinged in the runner 869. The plurality of vertical vibration rods 8610 are arranged in the second shock assembly 860, which can increase the vibration force in the vertical direction, thereby further enhancing the homogenizing effect on the refractory material in the stationary mold 400. An elastic pulling rope is fixed between each vertical vibration rod 8610 and the runner 869. Both the first friction wheel 854 and the second friction wheel 866 are in contact with the outer wall of the stationary mold 400. By arranging the first shock assembly 850 and the second shock assembly 860 on the first slider 810 and the second slider 820 to achieve a vibration knocking effect on the stationary mold 400, the vibration generated can achieve a homogenizing effect on the refractory material in the stationary mold 400, which can minimize the gaps between the refractory materials to the greatest extent, thereby improving the quality of the finished product after die-casting.

[0020] When the above device is in specific use, first, the refractory material principle is placed into the fixed mold 400. Subsequently, the driving component 840 is started to drive the first slider 810 and the second slider 820 to slide clockwise on the rectangular track 700. At this time, since both the first slider 810 and the second slider 820 are in a moving state, two first oscillation components 850 provided on the first slider 810 start to work. Due to the extrusion of the first friction wheel 854 against the outer wall of the fixed mold 400, under the action of friction, the first friction wheel 854 will rotate, thereby driving the first rotating rod 852 fixed to it to rotate. During the rotation of the first rotating rod 852, a plurality of first elastic knocking rods 853 fixed to its outside will rotate, thereby continuously knocking the outer wall of the fixed mold 400. Through the generated vibration, the gaps between the refractory materials are made as small as possible. At the same time, as the second slider 820 moves, the second oscillation component 860 starts to work. The basic principle is the same as above. The partial difference is that during the rotation of the second rotating rod 864, it will drive the first bevel gear 863 to rotate. Under the action of the first bevel gear 863 and the second bevel gear 868, it drives the third rotating rod 867 to rotate, and then drives the rotating wheel 869 to rotate. As the rotating wheel 869 rotates, the vertical vibration rod 8610 limited by the elastic pull rope gradually unfolds under the action of centrifugal force, thereby increasing the vibration force in the vertical direction, and further improving the homogenization effect on the refractory materials in the fixed mold 400; The vibration component 800 needs to move in a cycle on the rectangular track 700 for 5 - 6 circles and then perform die-casting operation. The moving mold 500 is pushed downward by the electric push rod 600. At this time, the refractory materials in the fixed mold 400 are die-cast into shape. After die-casting for a certain period of time, the moving mold 500 is driven by the electric push rod 600 to reset upward.

[0021] Example 2, see Figures 1 - 9, on the basis of Embodiment 1, in this embodiment, a linkage assembly 870 is assembled outside the second slider 820. The linkage assembly 870 includes an L-shaped support rod 871 fixed outside the second slider 820. A cross bar 872 is hinged to the bottom of the L-shaped support rod 871. A roller 873 is rotatably connected to the front end of the cross bar 872. A fixing plate 874 is fixed on the cross bar 872. A spring 875 is fixed between the fixing plate 874 and the L-shaped support rod 871. A plurality of ejector grooves are formed inside the fixed die 400, and an ejector assembly 900 is assembled in each ejector groove. The ejector assembly 900 includes an L-shaped hydraulic pipe 901. A first hydraulic rod 902 is slidably connected to a piston at one end inside the L-shaped hydraulic pipe 901. A second hydraulic rod 903 is slidably connected to a piston at the other end inside the L-shaped hydraulic pipe 901. A top plate 904 is fixed to the top end of the second hydraulic rod 903. Through the cooperation of the linkage assembly 870 and the ejector assembly 900, when the driving assembly 840 drives the first slider 810 and the second slider 820 to slide reversely on the loop track 700, the effect of automatic ejection can be achieved through the ejector assembly 900.

[0022] When the above device is in specific use, after die casting is completed, the driving assembly 840 drives the first slider 810 and the second slider 820 to slide reversely on the loop track 700. It should be noted that when the vibration assembly 800 is in the clockwise direction on the loop track 700, due to the one-way hinge between the L-shaped support rod 871 and the cross bar 872, no extrusion effect will be caused on the first hydraulic rod 902. When the driving assembly 840 drives the first slider 810 and the second slider 820 to slide reversely on the loop track 700, when the roller 873 contacts the first hydraulic rod 902, since the cross bar 872 can only rotate in one direction, the roller 873 will squeeze the first hydraulic rod 902. At this time, since the first hydraulic rod 902 is squeezed and retracted into the L-shaped hydraulic pipe 901, the liquid pressure in the L-shaped hydraulic pipe 901 becomes larger, which will cause the second hydraulic rod 903 to push the top plate 904 to move upward, ejecting the die-cast refractory material finished product from the fixed die 400, facilitating the staff to take out the finished refractory material.

[0023] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
