Die casting machine and its control method

Abstract

The present disclosure provides a die-casting machine, which includes a bottom platform and a top platform capable of moving in the vertical direction, the bottom platform includes a base with a receiving cavity, and a plurality of protrusions fixedly connected with the base and located inside the receiving cavity in the horizontal direction , a frame that is horizontally located in the accommodating cavity and capable of moving in the vertical direction, and a bottom plate that is positioned inside the frame in the horizontal direction and that can move vertically, wherein the bottom plate is provided with a plurality of through holes, each through The holes correspond to a bump; the control method includes: lowering the bottom plate to a first preset height; making the bottom platform receive concrete for the first time; lowering the frame to the first preset height; making the bottom platform receive concrete for the second time; making the bottom platform receive concrete for the first time; The top platform descends and compresses the top of the concrete; causes the base plate and frame to rise simultaneously and compresses the bottom of the concrete, and thus causes the concrete to form a cement slab. The die-casting machine disclosed in the present disclosure can avoid the breakage of the cement board when demoulding.

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 ...
