Lost foam drying production line

Abstract

The invention provides a lost foam drying production line. The lost foam drying production line comprises a drying room; the drying room is divided into a normal temperature area, an intermediate temperature area and a high temperature area, the normal temperature area, the intermediate temperature area and the high temperature area are separated through heat insulation separating walls, and a channel is formed between the heat insulation separating walls and the inner wall of the drying room; a suspension conveying chain is arranged in the drying room, penetrates through the channel and passes the normal temperature area, the intermediate temperature area and the high temperature area in sequence, and the suspension conveying chain is a closed chain; a lost foam is connected with the suspension conveying chain through hooks; a feeding station, a stirring station and a picking station are arranged in the positions, opposite to the suspension conveying chain, of the normal temperature area; and the intermediate temperature area and the high temperature area are internally provided with heating devices. Through the lost foam drying production line provided by the invention, the problems that an existing drying mode is low in drying efficiency, uneven in drying, long in duration, high in energy consumption and capable of damaging bodies of workers are solved.

Description

Technical field [0001] The invention relates to the technical field of lost foam casting, in particular to a casting lost foam drying production line. Background technique [0002] Lost foam casting is to bond and combine paraffin or foam models similar to the size and shape of the castings into model clusters. After coating refractory materials and drying, they are buried in dry quartz sand for vibration modeling, poured under negative pressure to gasify the model , The casting method in which liquid metal occupies the position of the model and forms a casting after solidification and cooling. Lost foam casting is a new process with almost no margin and precise molding. This process does not require mold taking, no parting surface, no sand core, so there is no flash, burr and draft angle of the casting, and it reduces the core Size error caused by combination. Compared with the traditional sand casting method, it can reduce a lot of machining time. [0003] After the lost foam ...
