Description

Technical Field

[0001] The utility model belongs to the technical field of acid-resistant brick production, and in particular relates to a forming mold for preparing antistatic acid-resistant bricks. Background Art

[0002] Acid-resistant bricks are also commonly called acid-resistant ceramic tiles. They are a high-performance building material with a compact structure, low water absorption, acid and alkali resistance, and corrosion resistance. The main components are generally quartz, feldspar and clay, and the raw materials are mixed and decomposed by high-temperature oxidation. Anti-static acid-resistant bricks are made on the basis of the production process of ordinary acid-resistant bricks. Anti-static functional powder is added during the firing process for physical modification, and then a kind of anti-static ceramic tile is prepared. It is usually used in some static-sensitive occasions, such as electronic warehouses, hospital operating rooms, semiconductor manufacturing workshops, etc. The use of anti-static ceramic tiles can effectively reduce the interference and harm caused by static electricity.

[0003] The production process of anti-static acid-resistant bricks includes mixing, forming, drying, firing and other processes. Among them, the forming process refers to filling the raw materials of anti-static acid-resistant bricks into the forming mold, compacting them with pressure by a hydraulic brick machine, and then demolding them to make anti-static acid-resistant bricks of specific shapes.

[0004] The existing brick machine forming molds are all fixedly set on the workbench just below the hydraulic pressure head, and one brick machine corresponds to one forming mold. After an acid-resistant brick blank is pressed and formed, it is necessary to demold the formed brick blank and take it out, then refill the brick blank raw materials into the mold, and then press the next brick blank. However, the existing molds are not convenient for demolding. Each demolding and refilling will waste a certain amount of time. Moreover, during the filling operation, the human hand directly reaches under the hydraulic pressure head, and there is a risk of accidental injury. Such operation leads to low efficiency in pressing the brick blank, affects the efficiency and output of brick making, and also poses certain safety hazards.

[0005] In addition, in the existing production method, a brick machine can only match one forming mold at a time and can only produce one type of brick. If you want to produce anti-static and acid-resistant bricks with different shapes, you must change the mold. Changing the mold will waste a lot of time and may even affect the delivery period and the company's reputation. Therefore, it is necessary to improve the existing brick machines, especially the forming molds. Utility Model Content

[0029] The technical solution of the present utility model will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments.

[0030] It should be noted that the terms “upper”, “lower”, “left”, “right”, “inner”, “outer”, etc. indicating directions or positional relationships are based on the drawings and are only for the convenience of description.

[0031] Example

[0032] like Figure 1-5 As shown, a forming mold for preparing antistatic acid-resistant bricks includes a brick machine 1, a hydraulic pressure head 2 arranged on the upper part of the brick machine, a workbench 3 arranged on the lower part of the brick machine, and a blanking mold arranged above the workbench.

[0033] A left operating table 4 and a right operating table 5 are respectively extended from the left and right sides of the workbench. A fixed track 6 is laid through the upper surfaces of the workbench and the left and right operating tables. Two mold trolleys 7 that can slide left and right are arranged above the fixed track.

[0034] The brick machine is also provided with a limiting mechanism for limiting the mold trolley from sliding into position; the limiting mechanism includes a limiting groove 10 provided in the middle of the brick machine, and a limiting block 11 provided inside the limiting groove and capable of sliding left and right. The limiting block can slide left and right in the limiting groove, and the limiting block can block and limit the left or right edge of the mold trolley.

[0035] The limit slot is a horizontal long hole opened on the front side wall of the brick machine, and the left and right ends of the limit slot are respectively provided with adjustment screws 12 for adjusting the sliding range of the limit block. By adjusting the extension length of the adjustment screw in the limit slot, the sliding range of the limit block can be adjusted, thereby realizing the limit positioning of the mold trolley parking position.

[0036] The blank making mold comprises a set of upper mold components and two sets of lower mold components.

[0037] The upper mold assembly includes an upper mold plate 13 and an outer mold frame 14. The upper mold plate is detachably mounted on the lower end of the piston rod of the hydraulic pressure head by bolts. A hydraulic lifting rod 15 is respectively arranged on the left and right sides of the hydraulic pressure head. The outer mold frame is suspended at the lower ends of the piston rods of the two hydraulic lifting rods.

[0038] The lower mold assembly includes a lower mold plate 16 and an inner mold frame 17. The lower mold plate is installed above the mold trolley. The inner mold frame is surrounded by the edges of the upper surface of the lower mold plate. A pressing forming groove for filling brick raw materials is formed between the inner mold frame and the lower mold plate. After the outer mold frame is pressed down into place, it is fitly sleeved on the outer side of the inner mold frame. After the upper mold plate is pressed down into place, it is fitly embedded on the inner side of the inner mold frame.

[0039] The upper template and the lower template are both rectangular flat plates, and the lower surface of the upper template and the upper surface of the lower template are respectively engraved with a flower pattern 18 and a flower pattern 2 19. The specific flower patterns on the upper and lower surfaces of the antistatic acid-resistant brick can be customized according to customer needs.

[0040] The outer mold frame is an integrally formed rectangular frame, and the left and right sides of the outer mold frame are rotatably hinged to the lower ends of the piston rods of the two hydraulic lifting rods through hinge seats 20. Under normal circumstances, the two hydraulic lifting rods of the outer mold frame are required to move completely synchronously, but in order to prevent the accidental breakage of the connection point between the piston rod and the outer mold frame caused by the incomplete synchronous lifting of the left and right sides of the outer mold frame, a non-rigid connection method is adopted.

[0041] The inner mold frame is a rectangular frame formed by four long frames 27 being spliced ​​and arranged end to end, and positioning holes are provided at the bottom of both ends of each long frame, and positioning pins 21 matching with the positioning holes are fixedly provided on the edges of the lower mold plate. When taking out the blank, the long frames of the inner mold frame can be removed to facilitate the demoulding and taking out of the formed brick blank. When the brick blank material is filled again, the long frames are put on, and the positioning pins are inserted into the positioning holes to complete the rapid splicing of the inner mold frame. When the brick blank is pressed, the integrally formed outer mold frame is fitted on the outside of the spliced ​​inner mold frame, which has a good restraining and holding effect on the inner mold frame, and can prevent the inner mold frame from expanding outward under pressure, thereby ensuring the forming effect of the blank making mold.

[0042] The inner side surfaces of the four frames of the outer mold frame and the outer side surfaces of the four long frames of the inner mold frame are also provided with wedge-shaped guide surfaces 22. During the pressing process of the outer mold frame, the wedge-shaped guide surfaces play an auxiliary guiding role, which is conducive to the perfect matching between the outer mold frame and the inner mold frame.

[0043] A driving mechanism for driving the mold trolley to slide left and right is also provided inside the workbench; the driving mechanism includes a driving sprocket 23 and a driven sprocket 24 rotatably mounted below the left and right ends of the fixed track, and a transmission chain 25 wound between the driving and driven sprockets. The bottoms of the two mold trolleys are connected to the transmission chain, and the driving sprocket is connected to a driving motor 26.

[0044] The bottom of the mold trolley is slidably connected to the fixed rail through a slider 8, and the bottom of each slider is fixedly connected to the transmission chain through a connector 9. The fixed rail is a linear guide rail, and the slider is a linear bearing matching the linear guide rail.

[0045] The driving motor is a forward and reverse motor, which drives the transmission chain to reciprocate left and right through the forward and reverse rotation of the driving motor, thereby driving the two mold carts to slide left and right and alternately stop directly under the hydraulic pressure head for brick pressing and forming. When the left mold cart completes the brick pressing operation, the upper mold plate and the outer mold frame rise, and the left mold cart moves to the left and moves out from under the hydraulic pressure head. At the same time, the right mold cart filled with brick raw materials moves to the bottom of the hydraulic pressure head, and the limit block blocks the left side of the right mold cart, thereby accurately positioning the parking position of the right mold cart, and then the brick pressing and forming begins. At the same time, the left mold cart performs the operation of taking out and refilling the formed bricks. After the right mold trolley completes the pressing of the brick blank, the upper template and the outer mold frame rise, the right mold trolley moves to the right, and at the same time the left mold trolley stops under the hydraulic pressure head again. The limit block forms a blocking limit on the right side of the left mold trolley, and the upper template and the outer mold frame are pressed down to press the brick blank again. This process is repeated by analogy to achieve alternating blank making operations, minimize the waste of production time, and improve the efficiency of anti-static and acid-resistant brick making.

[0046] The technical solution of the present invention is not limited to the above-mentioned specific embodiments. Without departing from the scope and spirit of the described embodiments, many modifications and changes are obvious to ordinary technicians in this technical field. Any technical deformation made within the spirit and principles of the present invention falls within the protection scope of the present invention.
