Problems solved by technology
[0002] Motor stator and rotor punching compound dies often have complex structures, many grooved punches, high precision requirements for parts, and small gaps. Some problems often occur in the existing structure during use. For example, when the guide part is working, the retainer is often ejected from the guide post by the spring. , if the retainer cannot return to the original position in time at the beginning of the next stroke, it will cause damage to the mold or even damage the press, so this design focuses on improving it

The invention relates to the field of the manufacturing of a motor and discloses a compound mould guide structure for the motor. The structure comprises a guide post, a retainer, a guide sleeve, a ball, a spring, a pull rod, a baffle block, a gland and a cushion cover, wherein the retainer is in non-clearance fit with the guide post and the guide sleeve respectively; the guide post is in conic-surface fit with the cushion cover; the spring is arranged outside the guide post and between the cushion cover and the retainer; the guide sleeve is fixed with an upper template; and the cushion cover is fixed with a lower template. The compound mould guide structure has the advantages of: 1, simple structure; 2, good using effect; and 3, high reliability.
Description
technical field [0001] The invention relates to the field of motor manufacturing, in particular to a motor compound mold guiding structure. Background technique [0002] Motor stator and rotor punching compound molds often have complex structures, many grooved punches, high precision requirements for parts, and small gaps. Some problems often occur in the existing structure during use. For example, when the guide part is working, the retainer is often ejected from the guide post by the spring. , if the retainer cannot return to the original position in time at the beginning of the next stroke, it will cause damage to the mold or even damage the press, so this design focuses on improving it. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a motor duplex mold guide structure, which can ensure the correctness of the retainer in each stroke of the mold, and avoid the misoperation due to its detachment from the g...
