Die-casting machine and control method thereof

Abstract

The invention provides a die-casting machine. The die-casting machine comprises a bottom platform and a top platform which can move in the vertical direction, wherein the bottom platform comprises a base with an accommodating cavity, a plurality of lug bosses which are fixedly connected to the base and are positioned inside the accommodating cavity in the horizontal direction, a side frame which is positioned in the accommodating cavity in the horizontal direction and can move in the vertical direction, and a bottom plate which is positioned at the inner side of a side frame in the horizontaldirection, and can move in the vertical direction; a plurality of through holes are formed in the bottom plate; and each through hole corresponds to a lug boss. A control method comprises the following steps: dropping a bottom plate to first preset height; enabling the bottom platform to receive concrete for a first time; dropping the side frame to first preset height; enabling the bottom platformto receive concrete for a second time; dropping the top platform and extruding the top of concrete; enabling the bottom plate and the side frame to simultaneously lift, and extruding the bottom of concrete, thereby forming a cement board by concrete. The die-casting machine disclosed by the invention can avoid a damage phenomenon during cement board de-moulding.

Description

technical field [0001] The disclosure belongs to the technical field of construction machinery, and specifically provides a die-casting machine and a control method thereof. Background technique [0002] The die-casting machine for cement board is a kind of equipment for die-casting concrete into cement board. Specifically, the die-casting machine generally includes a bottom platform and a top platform, wherein the bottom platform is usually provided with a mold (with grooves). The loose concrete is squeezed into a solid cement slab by placing rebar and wet concrete onto the bottom platform, then lowering the top platform and squeezing the concrete on the bottom platform. [0003] In order to reduce the amount of concrete on the premise of ensuring that the cement board has sufficient strength, the mold on the bottom platform is usually set in an uneven structure, so that one side of the cement board forms an uneven structure. [0004] However, the uneven mold often leads ...
