Automatic dip-coating device for large complex sand mold based on robot

Abstract

The invention discloses an automatic dip-coating device for a large complex sand mold based on a robot. The automatic dip-coating device comprises temporary storage tables, the robot, a mechanical arm, a dip-coating box and an inspection table, and is used for collecting the shape and size information of a product and controlling the mechanical arm to clamp the product by the robot, so that the manual operation is replaced, the labor intensity is reduced, and a feasible process is provided for brushing a large part; a dip-coating box soaking mode is used for replacing a brushing mode, so thatthe brushing time is shortened, the brushing effect is better, and the uniformity and thoroughness of coating of the inner surface and the outer surface of the sand mold are ensured; the sand mold does not need to be overturned, and hoisting equipment is not needed, so that the cost is saved; the robot controls the mechanical arm to automatically overturn, and redundant paint and impurities on thesurface of the sand mold and in a groove are removed, and the dip-coating box automatically feeds and supplements paint and alcohol in the dip-coating box, so that automatic stirring is carried out to prevent uneven concentration caused by paint precipitation.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a sand mold brushing technology. Background technique [0002] Traditional sand casting uses wooden molds or metal molds, which are placed in sand boxes, filled with a mixture of sand and bonding resin, and the sand molds are taken out after curing. In order to facilitate demoulding after casting, it is necessary to brush a layer of release agent on the surface of the mold, which is an alcohol-containing paint. The traditional brushing process is manual brushing, which requires a lot of work and labor intensity. The thickness of the brushing is uneven, and the sand mold must be turned over when painting the bottom surface. For large sand molds, it needs the cooperation of a lifting device to complete it. The production efficiency is low and unsafe. It is also inconvenient. [0003] It is convenient to brush the sand mold, to ensure the quality of the brush, and to i...
