Abstract

The invention discloses a water cooling machine shell heat core box electric heating device. The device comprises a mold body, a sand shooting plate, a pulling-out core body and a core supporting plate; the mold body is defined by multiple core box bodies and is provided with a cavity, the sand shooting plate is arranged on the upper portion of the cavity in a covering manner, the pulling-out corebody is arranged in the cavity, and the core supporting plate is arranged at the lower end of the cavity in a covering manner; the cavity is cylindrical, multiple heating pipes with the same number are arranged in each core box body, the heating pipes are arranged in the core box bodies in an arc array manner, and the distances between the heating pipes and the inner walls of the core box bodiesare the same. According to the water cooling machine shell heat core box electric heating device, a sand core can be more evenly heated.

Description

technical field [0001] The invention relates to an electric heating device for a hot core box of a water-cooled casing. Background technique [0002] In the current electric heating method, the size, specification, quantity, and distribution of the electric heating tubes used have not been accurately calculated, and basically rely on manual experience to determine the number, diameter, and distribution of the heating tubes; generally, no temperature sensor is installed, and the sand core The temperature change of heating and solidification has not been accurately analyzed by relevant software, and it can only be used afterwards. For the motor case waterway sand core with curved surface and curved shape, uneven heating often occurs, resulting in sand core deformation and filling, uneven bonding density and Defects such as external cooking and internal growth, as well as insufficient strength of the sand core, fractures occurred during the production process, resulting in the ...
