Problems solved by technology

The thermal insulation performance of the riser directly affects the feeding efficiency of the riser. In the ordinary metal mold casting process, the thermal insulation riser structure used is usually sprayed with asbestos powder in the riser for thermal insulation. The thermal insulation coating is easy to fall off. The problem of poor thermal insulation effect reduces the feeding effect of the riser, thus affecting the production quality of casting products

Abstract

The invention relates to a novel insulated riser structure. The novel insulated riser structure comprises a riser main body; a metal riser insert with an opening in the top end is arranged outside the riser main body in a sleeving mode; an exhaust pipe communicating with the inside of the riser main body is vertically arranged at the top end of the riser main body; a top cover is arranged at the open end of the metal riser insert; an exhaust plug column is vertically arranged on the top cover; a heat preservation layer is attached to the outer surface of the riser main body and is a superfine glass heat preservation cotton layer; and gaps formed by the inner side of the metal riser insert, the outer side of the heat preservation layer and the top cover are filled with heat preservation asbestos. According to the novel insulated riser structure, the heat preservation layer is arranged on the outer side of the riser main body and is the superfine glass heat preservation cotton layer, the metal riser insert is provided with the heat preservation asbestos, a double-layer heat preservation component is formed outside the riser main body, the problem that a heat preservation coating is prone to falling off due to the fact that a riser coating prepared by spraying asbestos powder is sprayed into the riser for heat preservation is solved, and meanwhile, the heat preservation effect is guaranteed, and the feeding effect of the riser is improved, so that the production quality of casting products is guaranteed.

Description

technical field [0001] The invention relates to the technical field of casting risers, in particular to a novel insulation riser structure. Background technique [0002] The riser is a supplementary part added to the top or side of the casting to avoid defects in the casting. It has the functions of preventing shrinkage, porosity, exhaust and slag collection. The main function of the riser is to feed shrinkage. The thermal insulation performance of the riser directly affects the feeding efficiency of the riser. In the ordinary metal mold casting process, the thermal insulation riser structure used is usually sprayed with asbestos powder in the riser for thermal insulation. The thermal insulation coating is easy to fall off. The problem of poor thermal insulation effect reduces the feeding effect of the riser, thereby affecting the production quality of casting products. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and p...
