Description

Technical Field

[0001] The utility model relates to the technical field of refractory brick blank making, in particular to a blank making device for hollow ball refractory bricks. Background Art

[0002] Before firing hollow ball refractory bricks, a forming machine is needed to press the brick powder of hollow ball refractory bricks into brick blanks. As shown in the brick blank forming machine, the core of the forming machine is a forming mold, which is generally composed of a mold bottom plate, a pressure head, two side plates and two end plates. After filling the brick powder in the mold cavity, the pressure head is driven downward by a hydraulic press to compact the soft brick powder according to the cavity pattern to form a brick blank. Then, through the jacking mechanism, the bottom plate is connected to the brick blank and pushed up. After the brick blank is pushed out of the mold, it is transferred and unloaded. Traditionally, when transferring the brick blank from the forming mold, manual lifting is mostly used to lift the brick blank together with the mold bottom plate from under the hydraulic press, and then unload the bottom, which is time-consuming and labor-intensive.
