Description

Technical Field

[0001] The invention relates to the field of brick making, and in particular to a core-pulling pressing head structure of a floor tile and a core-pulling forming method of the floor tile. Background Art

[0002] When making floor tiles with grooves on the surface, a mold with a protruding portion on the surface of a pressure head plate is usually used. The brick material in the mold box is pressed by the above mold, and then demolded to complete the molding of the floor tiles. If the grooves are deeper, a higher protrusion is required. During the pressing process, some of the brick material will be squeezed into the corner surrounded by the protrusion and the pressure head plate. If the pressure head plate and the protrusion leave the brick material at the same time, the brick material at the intersection of the brick surface and the groove will stick to the protrusion, causing the brick surface at the edge of the groove to collapse. At the same time, due to the large protruding height of the protrusion, the brick material stuck to the pressure head is difficult to remove with a rotating brush. Therefore, it is currently impossible to use a mold with a higher protrusion to directly mold floor tiles, resulting in shallow grooves on the brick surface directly pressed out by the existing mold. Summary of the invention

[0003] In view of this, an object of the present invention is to provide a core-pulling pressing head structure which can prevent brick materials from sticking to a mold and can press out floor tiles with deeper grooves.

[0012] Step 2: the pressure plate rises and separates from the mold box to carry out a second brick laying;

[0013] Step 3: The telescopic mechanism drives the core-pulling pressure head to expose the core-pulling pressure head from the pressure head plate, and the pressure head plate descends to press the bricks arranged in the mold box. The pressure head plate and the core-pulling pressure head descend at the same time and press on the bricks in the mold box, and the pressure head plate and the core-pulling pressure head are kept fixed, and then the bricks in the mold box are vibrated to compact the bricks in the mold box.

[0016] The present invention also proposes a core-pulling forming method for floor tiles: during forming, the core-pulling pressure head descends and presses on the brick material together with the pressure head plate to perform molding. After molding, the core-pulling pressure head retracts first, and the brick material adhered to the core-pulling pressure head is peeled off from the core-pulling pressure head due to the obstruction of the contacting pressure head plate. When the pressure head plate is separated from the brick material, the brick material will not stick to the mold, so the grooves on the molded brick surface are deeper and no surface collapse will occur.
