Die used for preparing motor peripheral shell of new energy automobile and equipment

Abstract

The invention provides a die used for preparing a motor peripheral shell of a new energy automobile and equipment, and relates to the technical field of motor peripheral shell casting. The die used for preparing the motor peripheral shell of the new energy automobile comprises a bottom die installing plate, a bottom die, side dies, a sand core, an upper die and an upper die installing plate; the bottom die is fixed to the bottom die installing plate, the multiple side dies are connected to the bottom die installing plate in a sliding manner and surround the peripheral side of the bottom die, and the sand core is fixed above the bottom die; the sand core comprises a plurality of annular parts and connecting parts, the multiple annular parts are arranged at intervals, and the connecting parts are located between any two adjacent annular parts for connecting the two adjacent annular parts; the upper die is cylindrical, one end of the upper die is fixed to the upper die installing plate, and the other end of the upper die is located in a hollow zone of the sand core; and a gap is reserved between the inner surface of each side die and the outer edge face of the sand core, and a gap isreserved between the inner surface of the sand core and the outer surface of the upper die.

Description

technical field [0001] The invention relates to the technical field of casting a motor peripheral casing, in particular to a mold and equipment for preparing a motor peripheral casing of a new energy vehicle. Background technique [0002] The cooling water channel of the existing automobile motor casing realizes the casting of the circulating cooling water channel of the motor casing by the combination of inner and outer rings. Inner ring mold preparation, inner ring blank die-casting molding, inner ring blank die-casting molding, inner ring blank heat treatment and inner ring machining are required to prepare the inner sleeve. Outer ring mold preparation, outer ring blank die-casting molding, Outer ring blank die-casting, outer ring blank heat treatment, outer ring machining and other steps to prepare the jacket, and then the inner and outer rings are combined and welded into one. [0003] However, there are relatively large cost and safety problems in this method, specifi...
