Abstract

The invention discloses a low pressure casting die for a multi-point isolated heat spot type large gearbox casing, which comprises a bottom die, a left side die, a right side die, an upper die, a front core pulling slide block, a back core pulling slide block, an inner cavity core, and a cooling system, wherein the cooling system is used for cooling the upper die at least, and comprises a cooling hole and a cooling pipe; the cooling hole is formed in the upper die; the cooling pipe extends into the cooling hole, and is used for continuously spraying a cooling medium into the cooling hole. The low pressure casting die for the multi-point isolated heat spot type large gearbox casing has the advantages that by arranging the cooling system capable of cooling the upper die, the over-high temperature of the die is prevented, the use performance of the die and the size precision of the processed part are ensured, the processing quality is improved, and the service life of the die is prolonged.

Description

technical field [0001] The invention relates to a mold, in particular to a low-pressure casting mold for a large-scale gear case with multiple isolated thermal sections. Background technique [0002] The low-pressure casting mold is a kind of mold used for industrial products to be formed by pressure casting. The molten metal is filled into the mold cavity under a certain pressure and solidified and molded while maintaining the pressure to be processed into parts. During the processing Affected by the molten metal, it will cause the temperature of the mold to rise and cause thermal deformation, which will change the structure of the cavity, resulting in large dimensional errors and poor quality of the processed parts, which is not convenient for subsequent processing; it will also cause the matching accuracy of the various parts of the mold to decrease , so that the performance of the mold is deteriorated and the service life is shortened. [0003] Therefore, in order to so...
