The utility model discloses a production mould of motor shell, including forming mechanism, cooling water adjusting mechanism and adjusting auxiliary mechanism, the forming mechanism includes upper module and bottom module, the cooling water adjusting mechanism includes adjusting
pipe and rotating sleeve, the adjusting auxiliary mechanism includes outer tooth ring and damping ring, and the forming mechanism realizes the accurate forming of motor shell through the cooperation of upper module, bottom module, forming block and forming groove, and the design of
injection moulding hole through forming block ensures that
injection moulding material fills evenly, optimizes
injection moulding path, reduces bubble and defect formation, and the combination design of adjusting
pipe and rotating sleeve is adopted to cooling water adjusting mechanism, realizes the accurate control to cooling
water flow, and the cooperation structure of spin -in block and plugging board can change the flow area of adjusting
pipe to adjust the
cooling rate, and spin -in block provides
constant pressure, ensures that the adjusting
system is stable and reliable.
