Description

Technical Field

[0001] The invention relates to the field of metal die-casting equipment, and in particular to a one-outlet six-rotary micro-motor rotor die-casting machine. Background Art

[0002] There are many application defects in the existing multi-station rotary one-outlet multi-die-casting machines, specifically: the adaptability of the main cylinder part of the multi-station die-casting machine to the workpiece is low. Specifically, when die-casting rotors with different stacking thicknesses, even if the end rings are the same, a slight change in length requires the overall replacement of the upper mold, which directly increases the mold investment cost and affects work efficiency; and the one-outlet multi-die-casting machine has the phenomenon of difficulty in demolding individual rotors from the upper mold every time the mold is opened; in addition, after the mold is opened, the existing die-casting machine still relies on the dovetail groove on the punch to degate, because the punch has size restrictions, resulting in the gate not being cleanly and thoroughly removed when die-casting a larger workpiece. When applied to a rotary die-casting machine, aluminum slag falls and accumulates under the turntable after the gate is pushed out, which not only affects the efficiency of continuous production, but also poses a risk of the turntable getting stuck.
