Description

Technical Field

[0001] This utility model relates to the field of compression molding, specifically to a self-cleaning multilayer refractory material mold. Background Technology

[0002] Refractory bricks are refractory materials with specific shapes and sizes. Based on their manufacturing process, they can be classified into fired bricks, unfired bricks, fused bricks, and refractory insulating bricks. Based on their shape and size, they can be classified into standard bricks, common bricks, and special-shaped bricks. Refractory bricks can be used as high-temperature building and structural materials for kilns and various thermal equipment, and can withstand various physicochemical changes and mechanical actions at high temperatures.

[0003] Before firing refractory bricks, the clay needs to be pressed into shape, which requires the use of corresponding molds. However, as the pressing process proceeds, clay residue may remain on the mold, resulting in defects in the subsequently pressed brick blanks and affecting the quality of the bricks.

[0004] A new type of self-cleaning multilayer refractory mold is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a self-cleaning multilayer refractory material mold.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A self-cleaning multilayer refractory material mold includes a side mold and a top mold. The side mold consists of four sets of directional side plates and movable side plates. The directional side plates are vertically slidably connected to the outer edge of the top mold. The lower side of the directional side plates is hinged to a movable side plate that can be flipped outward. The top mold, directional side plates and movable side plates together form a mold cavity with a bottom opening.

[0008] As a further embodiment of this utility model: a torsion spring is provided at the hinge joint between the movable side plate and the directional side plate, and the torsion spring always acts on the movable side plate to keep the movable side plate moving parallel to the directional side plate.

[0009] As a further embodiment of this utility model: the top mold includes a connecting top plate, a forming template and a guide post. The forming template is fixedly connected to the bottom of the connecting top plate. The outer side of the forming template is slidably connected to a directional side plate through the vertical guide post at the bottom of the connecting top plate. The side mold also includes a connecting mold frame, a driving straight handle and a connecting handle. The connecting mold frame is sleeved on the outer side of the directional side plate. The bottom surface of the connecting mold frame is fixed with a vertical driving straight handle. The other end of the driving straight handle is hinged to a linkage handle. The other end of the linkage handle is hinged to the movable side plate for transmission. At the same time, a rectangular guide side frame is fixedly connected to the connecting top plate below the connecting mold frame. Vertical passage holes are provided on all four sides of the guide side frame, and the driving straight handle passes through the passage holes.

[0010] As a further embodiment of this utility model, the lower edge of the guide side frame passage hole is rounded on the inner side.

[0011] As a further embodiment of this utility model: when the side mold is in the closed state, the bottom surface of the guide side frame is flush with the hinge position of the drive straight handle and the linkage handle. Beneficial effects

[0012] 1. The side mold of this utility model consists of four sets of directional side plates and movable side plates. The directional side plates are vertically slidably connected to the outer edge of the top mold. The lower side of the directional side plates is hinged to a movable side plate that can be flipped open outward. The top mold, directional side plates and movable side plates together form a mold cavity with a bottom opening. By designing the top surface structure and the side surface structure of the mold cavity separately, relative movement can be generated when the side surface structure moves upward, so that the brick blank can be demolded. At the same time, the top mold structure is used to clean the side mold structure to prevent the clay from sticking. The side mold is composed of two parts: directional side plates and movable side plates. By flipping open the movable side plates, the contact area between the side mold and the brick blank can be reduced, thereby reducing the resistance during demolding and preventing possible deformation of the brick blank during demolding.

[0013] 2. The bottom surface of the connecting mold frame of this utility model is fixed with a vertical drive handle, and the other end of the drive handle is hinged to a linkage handle. The other end of the linkage handle is hinged to the movable side plate for transmission. At the same time, a rectangular guide side frame is fixedly connected to the connecting top plate below the connecting mold frame. Vertical passage holes are provided on all four sides of the guide side frame. The drive handle passes through the passage holes. Through the four-bar linkage structure composed of the drive handle, linkage handle, movable side plate and directional side plate, and the guiding effect of the guide side frame on the linkage handle, the movable side plate will simultaneously flip outward and open during the demolding process of the side mold, so as to separate from the brick blank without the need for an additional driving source.

[0014] 3. When the side mold of this utility model is in the closed state, the bottom surface of the guide side frame is flush with the hinge position of the drive straight handle and the linkage handle. That is, the initial position of the guide side frame is set so that when the side mold is lifted, it will first drive the linkage handle into the passage hole of the guide side frame. This makes the lateral flipping of the movable side plate better than the vertical movement, and the flipping and opening first reduces the influence of friction of the brick material of the side mold.

[0021] The following description, in conjunction with the accompanying drawings of this utility model, will be presented... Figures 1-5 The specific technical solution of this utility model will be clearly and completely described.

[0022] Please see Figures 1-5 , Figure 1 This is a schematic diagram of the overall structure of an embodiment of the present utility model; Figure 2 This is a schematic diagram of the mold opening state of this utility model; Figure 3 This is a schematic diagram of the top mold structure of this utility model; Figure 4 This is a schematic diagram of the side mold structure of this utility model; Figure 5 This is a schematic diagram of the side mold in the closed state of this utility model.

[0023] This embodiment provides a self-cleaning multilayer refractory material mold, including a side mold 2 and a top mold 1. The side mold 2 consists of four sets of directional side plates 24 and movable side plates 25. The directional side plates 24 are vertically slidably connected to the outer edge of the top mold 1. The lower side of the directional side plates 24 is hinged to a movable side plate 25 that can be flipped outward. The top mold 1, the directional side plates 24 and the movable side plates 25 together form a mold cavity with a bottom opening.

[0024] By using a separate design for the top and side structures of the mold cavity, relative movement can be generated when the side structure moves upward, allowing the brick blank to be demolded. At the same time, the top mold 1 structure is used to clean the side mold 2 structure to prevent the clay from sticking. The side mold 2 is composed of two parts: a directional side plate 24 and a movable side plate 25. By flipping and opening the movable side plate 25, the contact area between the side mold 2 and the brick blank can be reduced, thereby reducing the resistance during demolding and preventing possible deformation of the brick blank during demolding.

[0025] A torsion spring is provided at the hinge of the movable side plate 25 and the directional side plate 24. The torsion spring always acts on the movable side plate 25 to keep the movable side plate 25 parallel to the directional side plate 24, thereby improving the flatness between the movable side plate 25 and the directional side plate 24 after mold closing.

[0026] The top mold 1 includes a connecting top plate 11, a forming template 13, and a guide post 14. The forming template 13 is fixedly connected to the bottom of the connecting top plate 11. The outer side of the forming template 13 is slidably connected to a directional side plate 24 through the vertical guide post 14 at the bottom of the connecting top plate 11. The side mold 2 also includes a connecting mold frame 21, a driving straight handle 22, and a connecting handle. The connecting mold frame 21 is sleeved on the outer side of the directional side plate 24. The bottom surface of the connecting mold frame 21 is fixed with a vertical driving straight handle 22. The other end of the driving straight handle 22 is hinged to a linkage handle 23. The other end of the linkage handle 23 is hinged to the movable side plate 25 for transmission. At the same time, a rectangular guide side frame 12 is fixedly connected to the connecting top plate 11 below the connecting mold frame. Vertical passage holes are provided on all four sides of the guide side frame 12, and the driving straight handle 22 passes through the passage holes.

[0027] By means of the four-bar linkage structure consisting of the drive straight handle 22, the linkage handle 23, the movable side plate 25 and the directional side plate 24, and the guiding effect of the guide side frame 12 on the linkage handle 23, the movable side plate 25 will flip outward and open synchronously during the demolding process of the side mold 2, so as to separate from the brick blank without the need for an additional driving source.

[0028] Specifically, the lower edge of the passage hole of the guide side frame 12 is rounded on the inner side. The rounded edge improves the smoothness of the hinge between the drive straight handle 22 and the linkage handle 23, and avoids structural damage caused by jerking, which affects operation.

[0029] Specifically, when the side mold 2 is in the closed state, the bottom surface of the guide side frame 12 is flush with the hinge position of the drive straight handle 22 and the linkage handle 23;

[0030] That is, the initial position of the guide side frame 12 is set so that when the side mold 2 is lifted, it will first drive the linkage handle 23 into the passage hole of the guide side frame 12, so that the lateral flipping of the movable side plate 25 is better than the vertical movement, and the flipping and opening is performed first to reduce the influence of the friction of the brick material on the side mold 2.

[0031] When implementing the technical solution described in this embodiment, during the demolding process, when the drive source drives the side mold 2 to rise, the rise of the connecting mold frame 21 and the drive straight handle 22 will drive the inclined linkage handle 23 into the passage hole of the guide side frame 12. Through the guiding effect of the passage hole, the movable side plate 25 of the side mold 2 is turned outward and opened. The lower half of the side mold 2 is demolded outward first, reducing the demolding resistance of the subsequent extrusion demolding. As the movable side plate 25 is fully turned outward and opened, the vertical driving force of the continuing to rise connecting mold frame 21 and drive straight handle 22 is guided to the directional side plate 24 through the linkage handle 23 and the movable side plate 25, driving the directional side plate 24 to rise synchronously and undergo relative displacement with the forming template 13 of the top mold 1, so that the side wall of the brick blank is completely separated from the side mold 2, and demolding is achieved. At the same time, the forming template 13 can also scrape the surface of the directional side plate 24 to prevent the mud from sticking. Finally, through the additional lateral lifting mechanism, the separation from the top mold 1 can be achieved, and the pressing and demolding of the brick blank is completed.
