A kind of skateboard brick pressing brick mould

Abstract

The invention relates to a sliding-brick brick pressing die, and belongs to the technical field of skateboard-brick production. The sliding-brick brick pressing die comprises an upper hammer head assembly and a lower hammer head assembly. The lower hammer head assembly comprises a lower hammer head base and a lower hammer head which is installed on the lower hammer head base. A floating plate is arranged on the upper portion of the lower hammer head base. A gap adjusting mechanism is arranged on the lower portion of the floating plate. The floating plate is provided with a mold box. The mold box is internally provided with a mold core. The periphery of the mold core is provided with floating bottoms. The periphery of each floating bottom is provided with mold bottoms. During material adding and tapping stages, the gap adjusting mechanism makes the floating plate rise, and the depth of the floating bottoms is higher than the depth of the mold bottoms; during a brick pressing stage, the gap adjusting mechanism makes the floating plate lower, and the depth of the floating bottoms is the same with the depth of the mold bottoms. The sliding-brick pressing die mould has the advantages that through changes of the mould depth of edge margin positions in the material adding, tapping and brick molding processes, the compact degree of the edge margin positions can be improved, and the anti erosion properties of sliding bricks can be improved.

Description

technical field [0001] The invention relates to a mold for pressing bricks of sliding boards, which belongs to the technical field of production of sliding boards, and is especially suitable for molding of sliding boards with slits. Background technique [0002] As a functional refractory material for steelmaking, sliding bricks are used under harsh conditions. Therefore, the service life and safety of sliding bricks are important evaluation indicators. The forming process is a key process in the production and manufacture of skateboard bricks. The density and uniformity of each part of the skateboard brick during the forming process have an important impact on the performance and use effect of the skateboard brick. In the traditional brick press mold, it is highly dependent on the workers' distribution methods and pressurization process, and it is prone to the problem of poor molding effect caused by insufficient manual distribution, especially when producing skateboard bri...

Problems solved by technology

In the traditional brick press mold, it is highly dependent on the workers' distribution methods and pressurization process, and it is prone to the problem of poor molding effect caused by insufficient manual distribution, especially when producing skateboard bricks with slits (this kind of skateboard bricks are mainly Used in sliding nozzles with a female-to-female fit), such as figure 1 As shown, the protruding part 1 in the middle is the slit, and the thickness of the slit 1 is greater than the thickness of the plate body 2, so it is necessary to pile more materials at the slit, but at present, it is only based on manual control, and most of them are manually pressed. The operation method of stacking, firstly, the stacking needs to be mastered manually, and it is difficult to obtain precise control; secondly, the stacking at the slit is added in stages, and the stress of the feeding is different, which will cause the problem of inconsistent density
