Detailed Description
Referring to fig. 1-4, an injection mold for a motor pole tooth assembly comprises a lower fixing plate 1, mold feet 2, an ejector plate 3, a movable mold plate 4 and a movable mold core assembly; the lower fixed plate is connected with the movable template through a mold leg, a cavity 5 is formed in the mold leg, and two ejector pin plates are arranged in the cavity;
the movable mould plate is provided with a sliding chute, one end of the sliding chute is opened, and the movable mould core assembly is arranged in the sliding chute 7 in a sliding way. Because activity movable mould core subassembly slides and at opening 8 departments roll-off in the spout, be convenient for like this change activity movable mould core subassembly, save time during the injection moulding adds man-hour, improve production efficiency.
The movable die core assembly sequentially comprises a movable die core 9, an upper pressing plate 10 and a lower pressing plate 11 from top to bottom; the movable mold core is provided with at least four mold cavities 12 for placing the polar teeth, and each mold cavity consists of nine cavities 13. The cavity is opened for accommodating the pole teeth, nine pole teeth form a pole tooth component for the motor, and therefore a cavity component is formed by nine cavities (according to the characteristics of an injection molding product); four groups of mold cavities are uniformly distributed on one movable mold core to improve the injection molding production efficiency.
