<p>A core pulling molding device of a pressure-type hollow brick machine comprises an upper pressure head (1), a mold framework (2) and a lower mold (3). Mold cavities (20) are formed in the mold framework, and the upper pressure head and the lower mold are respectively positioned above and below the mold cavities. A mold core plate (4) is arranged below the lower mold, and mold core rods (41) which can penetrate slidingly through the lower mold and extend upwards into the mold cavities are arranged on the mold core plate. In the production process of hollow bricks, the invention makes the material distribution, molding and demolding easier.</p> |
