Description

Technical Field

[0001] This utility model relates to the field of die casting mold technology, and in particular to a motor rotor die casting mold with a cooling structure. Background Technology

[0002] Die casting molds are molds used in a method of casting liquid forging. They are mainly used to press molten metal into the mold cavity, where it cools and solidifies under high pressure to form parts of specific shapes and sizes.

[0003] Motor die casting molds are die casting molds used to produce motor housings or other motor-related parts; motor die casting molds typically consist of two main parts: a fixed mold and a moving mold; the fixed mold is mounted on the fixed platen of the die casting machine, and the moving mold is mounted on the moving platen of the die casting machine, and moves with the mold closing device of the die casting machine to realize mold locking and mold opening;

[0004] Existing die-casting molds lack cooling structures, resulting in slow natural cooling of the die-cast motor rotor within the mold. This causes the mold to remain occupied by the high-temperature casting for an extended period, hindering the rapid processing of subsequent die-castings and impacting overall production efficiency. Furthermore, after completing the die-casting of one rotor, the equipment requires cleaning and preparation before proceeding to the next, leaving it idle and reducing equipment utilization. Therefore, this paper proposes a die-casting mold for motor rotors with a cooling structure to address these issues. Utility Model Content

The fixed mold is engaged with the bottom of the moving mold via the limiting posts and limiting holes. The top of the fixed mold is positioned at a distance from a... A limiting post two is fixedly connected at equal intervals along the diagonal center. A limiting hole two is opened at equal intervals from the center of the other diagonal on the top of the fixed mold two. Multiple molding chambers are opened at equal intervals from the center inside the fixed mold two.
