High-efficiency and energy-saving aluminum alloy evaporative pattern casting production line

Abstract

The invention discloses a high-efficiency and energy-saving aluminum alloy evaporative pattern casting production line. The high-efficiency and energy-saving aluminum alloy evaporative pattern casting production line comprises a sand box automatic circular line, wherein a plurality of box bearing carts which move along a conveying line and are used for bearing sand boxes are arranged on the sand box automatic circular line; the sand boxes are borne on the box bearing carts; the box bearing carts sequentially pass through a bottom sand adding station, a model cluster storing station, a sand filling and modeling station, a pouring station, a casting discharging station and a sand falling station on the conveying line through a servo box pushing system; the pouring station comprises a pouring machine and a tundish changing system; a casting taking robot for taking out castings in the sand boxes is arranged at the casting discharging station; and a bottom-dump type sand falling device for dumping molding sand in the sand boxes from the bottoms of the sand boxes is arranged at the sand falling station, or a box turning machine is adopted for automatically turning over the boxes to finish the sand falling. The production line has the characteristics of high degree of automation, high production efficiency, stability, reliability, energy conservation, environment friendliness and the like.

Description

technical field [0001] The invention relates to the field of casting, more specifically, it relates to a high-efficiency and energy-saving aluminum alloy lost foam casting production line. Background technique [0002] Lost foam casting (also known as negative pressure dry sand solid mold casting) is a solid mold casting in which foam plastic molds use binder-free sand combined with vacuum technology. After being coated with refractory paint and dried, it is buried in dry quartz sand for vibration molding, poured under negative pressure, liquid metal occupies the position of the model, solidifies and cools to form a new casting method. [0003] The existing lost foam casting production line is provided with two or more sand box circulation lines arranged in parallel, and the sand filling molding station, pouring station, sand outlet station, etc. are sequentially set on the sand box circulation line, and a ferry car is set at the end To realize the transfer between differen...
