Pouring ladle with controlling mechanism of iron water flow

Abstract

The invention relates to a casting ladle with a molten iron flow control mechanism. The casting ladle consists of a ladle frame and a ladle, wherein the ladle is provided with a ladle spout. The ladle frame is provided with a vertical beam vertically and glidingly. A horizontal beam is arranged on the upper end part of the vertical beam. The horizontal beam is vertically provided with a check block on one end corresponding to the ladle spout. A motor driving the vertical beam to do vertical movement is arranged on the ladle frame at a position corresponding to the bottom of the vertical beam. The casting ladle adopts a central control system to send a signal to a servo motor using gears and racks to realize the vertical movement of the vertical beam according to digital revolution given by a controller, realizes precise multi-point positioning displacement control with a digital control signal, and can cast stably and precisely compared with the prior pouring mode of casting ladle. The casting ladle is suitable to be used for casting castings which are complex in shape and light in mass and volume and is suitable for adjusting iron flow during mass product casting.

Description

technical field [0001] The invention relates to a ladle in casting equipment, in particular to a ladle with a molten iron flow control mechanism. Background technique [0002] In the casting process, the hollow sand mold is firstly made by an automatic molding machine, then high-temperature molten iron is poured into the formed hollow sand mold and the molten iron fills the space inside the hollow sand mold, and finally the rough embryo of the product is made by removing the sand mold after cooling. In the above casting process, the ladle completes the loading and pouring of high-temperature molten iron. The ladle is composed of a ladle body and a ladle nozzle. The ladle body is fixed on the ladle frame and carries high-temperature molten iron inside. When the ladle frame is in the When rotating under the instruction of the control system, the molten iron in the ladle flows out from the notch made at the upper end of the ladle nozzle and pours into the hollow sand mold. At ...

AI Technical Summary

Problems solved by technology

At present, in the casting process, the outflow of molten iron per unit time is controlled by the rotation angle of the ladle frame, but because the total weight of the ladle body and its internal molten iron and the ladle frame is relatively large, the control result is not very good Precise, that is, the outflow of molten iron per unit time is not controlled very precisely, so that when casting some accessories with complex shapes, small quality and volume, there will be problems of over-pouring or under-pouring, which not only wastes molten iron, but also casts quality cannot be guaranteed
