Automatic blowing machine before casting

Abstract

The invention relates to an automatic blowing machine before casting. The automatic blowing machine comprises a mold lifting system, an overturning system and a blowing system. The automatic blowing machine is characterized in that the blowing system comprises a blowing nozzle; the blowing nozzle is communicated with an air way and a control system; the overturning system comprises an overturning bracket, an overturning shaft, an overturning cylinder, an overturning shaft base and a roller way frame; and the overturning shaft respectively penetrates through holes of the overturning shaft base and the overturning bracket. After the automatic blowing machine before casting is adopted, the overturning cylinder enables the roller way frame to overturn surrounding the overturning shaft, and the blowing nozzle blows residual sand and slag impurities in a casting cavity so as to remove the residual sand and the slag impurities in the casting cavity, so that the inherent quality of cast products is improved when products are cast at the next time.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an automatic purging machine before pouring. Background technique [0002] As we all know, in the process of casting parts, before casting, it is necessary to clean the residual sand that was originally left in the casting cavity to ensure that the recast product has no blisters and improve the quality and yield of the product. However, in the past, manual beating was used to remove sand, which was not only labor-intensive, time-consuming, but also unable to remove all the sand, resulting in trachoma on the cast product, reducing the yield and increasing the cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic purging machine before casting, which can automatically purify and clean the residual sand and slag in the casting cavity before casting, so as to improve the internal quality of casting products.
