Description

Technical Field

[0001] The utility model relates to a refractory brick discharging structure and belongs to the field of refractory brick production equipment. Background Art

[0002] When using a brick press to produce refractory bricks, the strong pressure will affect the ejection mechanism at the lower end of the brick bed when the brick is pressed into shape. Under long-term influence, the ejection plate of the brick bed will be deformed, thereby damaging the hydraulic cylinder of the ejection mechanism. Therefore, a new structure needs to be designed to increase the service life of the hydraulic cylinder. At the same time, the center of gravity of the bottom plate is easily offset when ejecting from the mold, and the brick bed is tilted out of the sleeve, causing the brick bed to crack. Utility Model Content

[0003] The purpose of the utility model is to provide a refractory brick discharging structure, which can effectively solve the above-mentioned problems.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] It includes an installation box and a forming die arranged on the upper end surface of the installation box;

[0006] The molding die is provided with an ejector plate, and the lower end of the ejector plate is provided with an ejection structure;

[0007] The ejection structure includes a hydraulic cylinder, the upper end of the piston of the hydraulic cylinder is installed on the lower end surface of the ejection plate; wherein, a lifting column is slidably arranged in the piston, a mounting plate is provided on the upper end surface of the lifting column, and a spring is provided between the lower end surface of the mounting plate and the upper end surface of the cylinder body of the hydraulic cylinder.

[0008] Furthermore: a slide groove is provided on the upper part of the piston, the lifting column is slidably provided in the slide groove, and a retaining ring is provided at the upper notch position of the slide groove, and a limiting ring is provided on the lower end surface of the lifting column.

[0009] Furthermore: a support plate is provided in the middle position of the upper end surface of the installation box, and the lower end of the support plate is connected to the ejection structure; and a limiting column is also provided on the lower end surface of the support plate, and a limiting hole matching the limiting column is provided in the installation box.

[0010] Further: the installation box includes a platform plate, a box body is provided at the lower end of the platform plate, a folding plate is provided in the box body, one end of the folding plate is fixed to the inner wall of the box body, and the other end is fixed to the bottom of the box body, and the limiting holes are provided on the platform plate and the folding plate.

[0011] Furthermore: the support plate includes an integrally formed rectangular plate and a conical panel, the conical panel is arranged at the lower end of the rectangular plate; and a bracket for mounting the support plate is provided in the platform plate.

[0012] Furthermore: the forming mold includes four enclosed vertical plates and reinforcing ribs installed on the sides of the vertical plates, and the ejector plate is slidably arranged in the forming mold.

[0013] The beneficial effects are:

[0014] This device is equivalent to an improvement to the structure of the piston. When the hydraulic cylinder is not activated, the piston will partially retract and not contact the ejector plate. However, due to the installation of the lifting column, the mounting plate located at the upper end of the lifting column is connected to the ejector plate. When the ejector plate is slightly deformed, it is directly transmitted to the mounting plate, which then drives the lifting column to slide downward along the piston of the hydraulic cylinder. At this time, no force is applied to the piston, which can extend the service life of the hydraulic cylinder.

[0015] At the same time, in order to make the support plate drive the ejector plate to rise vertically and stably, a limit column is set to effectively prevent the center of gravity of the ejector plate from shifting, which may cause damage to the forming mold and the brickwork.

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] It should be noted that, in the description of the present invention, unless otherwise specified, “multiple” means two or more; the terms “upper”, “lower”, “left”, “right”, “inside”, “outside”, “front end”, “rear end”, “head”, “tail”, etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] Furthermore, the terms "first," "second," "third," etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0026] At the same time, in the description of this utility model, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can mean fixed connection, detachable connection, or integral connection; it can be mechanical connection or electrical connection; it can be direct connection or indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0027] See Figure 1 This is an embodiment of a refractory brick discharging structure of the utility model.

[0028] The brick press comprises an installation box 1 and a forming mold 2 arranged on the upper end surface of the installation box 1; a brick pressing mechanism is arranged above the forming mold 2; when in use, concrete material can be added to the forming mold 2, and then the brick pressing mechanism is operated to press down to press the concrete material into a brick shape;

[0029] After the pressed bricks are formed, they need to be taken out of the forming mold 2. The bottom surface of the forming mold 2 in this device is composed of an ejector plate 7, which can slide in the forming mold 2. At the same time, an ejector structure 3 is provided at the lower end of the ejector plate 7; the staff can operate the ejector structure 3 to push the ejector plate 7 up. At this time, the ejector plate 7 can be ejected with the pressed refractory bricks, making it convenient for the staff to take them out.

[0030] The ejection structure 3 in this device includes a hydraulic cylinder 31, the upper end of the piston 32 of the hydraulic cylinder 31 is mounted on the lower end surface of the ejection plate 7;

[0031] Therefore, the main force providing thrust is the hydraulic cylinder 31. However, when the brick pressing mechanism presses bricks, the strong pressure will be transmitted to the ejector plate 7 through the concrete material, and the ejector plate 7 will be slightly deformed. This deformation is then transmitted by the ejector plate 7 to the piston 32 end of the hydraulic cylinder 31, causing the hydraulic cylinder 31 to be under pressure. Over time, the service life of the hydraulic cylinder 31 will be reduced. Therefore, in order to prevent the hydraulic cylinder 31 from being directly subjected to the force generated by the slight deformation of the ejector plate 7, the device is provided with the following structure:

[0032] A lifting column 33 is slidably provided in the piston 32, and a mounting plate 34 is provided on the upper end surface of the lifting column 33;

[0033] See Figure 3 , this device is equivalent to improving the structure of the piston 32. When the hydraulic cylinder 31 is not activated, the piston 32 will partially retract and will not contact the ejection plate 7. However, due to the provision of the lifting column 33, the mounting plate 34 located at the upper end of the lifting column 33 is connected to the ejection plate 7; when the ejection plate 7 is slightly deformed, it will be directly transmitted to the mounting plate 34, and then drive the lifting column 33 to slide downward along the piston 32 of the hydraulic cylinder 31. At this time, no force will be applied to the piston 32, which can extend the service life of the hydraulic cylinder 31.

[0034] At the same time, a spring 35 is provided between the lower end surface of the mounting plate 34 and the upper end surface of the cylinder body of the hydraulic cylinder 31 in this device;

[0035] The spring 35 is in a stretched state after the piston 32 contracts. At this time, the spring 35 provides a downward pulling force to the mounting plate 34, and the ejector plate 7 can be firmly pulled to the bottom of the forming mold 2 through the mounting plate 34, which is convenient for subsequent brick pressing operations.

[0036] See Figure 4 During the ejection operation, the hydraulic cylinder 31 pushes the piston 32 upward. At this time, the stretched state of the spring 35 begins to shrink, and the mounting plate 34 gradually approaches the upper end surface of the piston 32 until the mounting plate 34 is completely pressed against the upper end surface of the piston 32. At this time, the mounting plate 34, the lifting column 33, and the piston 32 form a whole, which together provide thrust to the ejection plate 7; at the same time, when the mounting plate 34 contacts the upper end surface of the piston 32, the spring 35 is in a normal non-elastic state.

[0037] A slide groove 36 is provided on the upper portion of the piston 32 , and the lifting column 33 is slidably provided in the slide groove 36 . A retaining ring 37 is provided at the upper notch position of the slide groove 36 , and a limit ring 38 is provided on the lower end surface of the lifting column 33 .

[0038] The slide groove 36 in this device is mainly used to facilitate the lifting column 33 to drive the mounting plate 34 to move up and down, and the retaining ring 37 and the limiting ring 38 are mainly provided to prevent the lifting column 33 from sliding out of the slide groove 36.

[0039] A support plate 4 is provided in the middle of the upper end surface of the installation box 1, and the lower end of the support plate 4 is connected to the ejection structure 3; and a limiting column 5 is also provided on the lower end surface of the support plate 4, and a limiting hole 6 matching the limiting column 5 is provided in the installation box 1.

[0040] The support plate 4 of this device is mainly used to facilitate the lifting of the ejection plate 7. Because the area of ​​the upper end surface of the mounting plate 34 is too small, the support plate 4 can be used to increase the contact area with the ejection plate 7. At the same time, in order to enable the support plate 4 to drive the ejection plate 7 to rise vertically and stably, a limit column 5 is set, which can effectively prevent the center of gravity of the ejection plate 7 from shifting, resulting in damage to the forming mold 2 and damage to the brick.

[0041] The installation box 1 includes a platform plate 11, a box body 12 is provided at the lower end of the platform plate 11, a folding plate 13 is provided in the box body 12, one end of the folding plate 13 is fixed to the inner wall of the box body 12, and the other end is fixed to the bottom of the box body 12, and the limiting hole 6 is provided on the platform plate 11 and the folding plate 13.

[0042] There are four limiting holes 6 in the present device, two of which pass through the platform plate 11 and two pass through the folding plate 13 , so that the limiting column 5 can be more stable.

[0043] The support plate 4 includes an integrally formed rectangular plate 41 and a tapered panel 42 . The tapered panel 42 is provided at the lower end of the rectangular plate 41 . A bracket for mounting the support plate 4 is provided in the platform plate 11 .

[0044] In this device, the support plate 4 is configured as a rectangular plate 41 and a conical panel 42. On the one hand, the rectangular plate 41 is used to push the ejection plate 7, and on the other hand, the conical panel 42 can be used to drop the entire support plate 4 into the bracket in the platform plate 11; the inclined surface of the side of the conical panel 42 can correct the position of the entire support plate 4, and at the same time, the inclined groove surface of the platform plate 11 can provide bearing capacity for the support plate, so that the support plate 4 is stable during the downward pressing and forming.

[0045] The forming mold 2 includes four enclosed vertical plates 21 and reinforcing ribs 22 installed on the sides of the vertical plates 21 . The ejector plate 7 is slidably disposed in the forming mold 2 .

[0046] The forming mold 2 in this device can be selected according to the shape of the brick. The forming mold 2 in this application document is mainly used for forming rectangular bricks.

[0047] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
