Abstract

The invention belongs to the technical field of casting machining, and particularly designs a low-pressure casting die for a new energy automobile motor shell with an end cover. The low-pressure casting die comprises an upper die, a side die set and a lower die. The upper die comprises an upper die base, an upper die head and an upper die core set. The upper die base and an upper die core set arefixedly connected through the upper die head. The lower die comprises a lower die base and a lower die core which are fixedly connected. The side die set is formed by three mutually-matched side dies.When the upper die, the side die set and the lower die are assembled, a motor shell pouring cavity is defined by the upper die core set, the side dies and the lower die core. By adoption of the abovescheme, the low-pressure casting die has the beneficial effects that the whole set of die is divided into three parts, meanwhile, the side die with the largest size is divided into three parts, the size of each part is greatly reduced, the structure is simplified, and machining is convenient.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles and specifically designs a low-pressure casting mold for a new energy vehicle motor casing with an end cover. Background technique [0002] The new energy vehicle motor case is a very important structure in the new energy vehicle engine. Due to the limitation of the battery life of the new energy vehicle, it is necessary to reduce the weight of the parts as much as possible. Most of the existing new energy vehicle motor cases use the fuselage and terminal The covers are processed separately and then assembled and matched. Such a design not only makes the processing of the motor casing complicated, but the most important mechanism makes the final motor casing have a higher quality. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a low-pressure casting mold for a new energy vehicle motor...
