Description

Molding production line arrangement structure for casting complex castings by sand lined iron mold

Technical Field

The utility model belongs to the technical field of the complicated foundry goods production facility of production engine, concretely relates to molding production line arrangement structure of complicated foundry goods of sand lined metal mould casting.

Background

The iron mold sand-coated casting is a casting process of coating a thin layer of precoated sand on the inner cavity of a metal mold box to form a casting mold. After the molding is finished, the upper box and the lower box are matched at a box closing machine and then poured.

The existing iron mold sand-lined process molding production line has the problems that when a molding host is used for molding, an upper box and a lower box of a sand box are required to be manufactured at the same time, then the upper box and the lower box are turned by a turning machine on the production line and then are combined, and a casting production link is carried out, so that the related control program is complex; if a casting (such as a cylinder cover) with a complex structure is produced by sand-lined iron mold casting, the upper box only needs to be simply sprayed, modified and blown clean to disperse sand, the beat is 20 seconds, but the lower box needs to be modified, manually brushed, sprayed, modified with paint, subjected to multiple mud cores and subjected to core setting and then inspection, the sand is blown clean to disperse sand, and a filter screen and a gasket are placed, and the beat is about 5 minutes. Because the lower box work load is greater than the upper box work load, the whole circulation of the sand box is slow, so that the efficiency is not high, and the production efficiency is low. In the process of actually producing the cylinder cover, the phenomenon that the sand box is well heated in each wheel, but because the lower box is slow to flow, the upper box occupies half of stations, so that the continuous mold injection cannot be carried out, waiting is needed, and meanwhile, the temperature of the sand box is reduced and the sand box needs to be heated again exists, so that the production efficiency is greatly influenced. When one production line can not meet the production requirement, two identical production lines need to be purchased, and the input cost, the equipment floor area and the manufacturing cost are higher. If the product is updated, the structure is changed greatly, the product is eliminated and the like, the sand box is scrapped completely in the early stage, and the loss is huge. Therefore, the key for improving the circulation speed of the lower box is to improve the production of complex parts by the sand lined metal mold process.
