Core shooter for new-energy-vehicle motor shell spiral water channel integral sand core

Abstract

The invention discloses a core shooter for a new-energy-vehicle motor shell spiral water channel integral sand core. The core shooter comprises a bottom die, a core pulling die mechanism, a left die closing mechanism and a right die closing mechanism and is characterized in that the bottom die is provided with a semicircular groove, a first cavity is arranged in the semicircular groove, the left die closing mechanism comprises a first die closing part, the inner side of the first die closing part is provided with a second cavity, the right die closing mechanism comprises a second die closing part, the second die closing part is provided with a third cavity, the core pulling die mechanism comprises cylinder, and the cylinder, the first cavity, the second cavity and the third cavity form a fourth cavity matched with the spiral water channel integral sand core. The core shooter has the advantages that the fourth cavity matched with the spiral water channel integral sand core can be formedby the bottom die, the core pulling die mechanism and the die closing parts of the left die closing mechanism and the right die closing mechanism, and accordingly ceramsite can be injected into the fourth cavity to integrally form the spiral water channel integral sand core, the forming operation of the spiral water channel integral sand core is simplified, and the forming speed of the sand coreis increased while the forming quality of the sand core is increased.

Description

technical field [0001] The invention relates to the technical field of casting sand cores, in particular to a new energy automobile motor housing spiral water channel integrated sand core core shooter. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies and new structures. The new energy vehicles on the market now use the motor as the power drive device. Due to the high speed and high heat generation of the motor, a spiral water cooling channel is generally provided inside the motor housing to cool down and dissipate heat. Therefore, it is necessary to produce motor housings with water-cooled structures. [0003] The current process for producing motor housings with water-cooling structures is as follows: pour molten aluminum into a die-casting mold, which is pre-ins...
