Brick extruding machine core tool for producing hollow wave bricks

The invention provides a brick extruding machine core tool for producing hollow wave bricks. The brick extruding machine core tool comprises a hollow mold, a core rod, a core shell, a core frame and amovable mold. After pug is extruded into the core tool, the core frame and the core rod are recombined into a whole, and then the pug forms a hollow part by the hollow mold to be extruded into hollowgreen bricks. An included angle is formed between the movement direction of the movable mold and the extrusion direction of the green bricks, the movable mold is periodically away from or close to the hollow mold, the hollow wave green bricks can be continuously produced, and the hollow wave bricks are manufactured after cutting. 本发明提供了一种生产空心波浪砖的挤砖机芯具，包括空心模、芯杆、芯壳、芯架和动模。泥料被挤入芯具后，经过芯架和芯杆重新结合成一个整体，再经过空心模后，泥料形成空心被挤出成空心的砖坯。动模的运动方向与砖坯的挤出方向具有夹角，通过动模周期性地远离或靠近空心模，可连续生产空心波浪形砖坯，并在切割后制成空心波浪砖。
