On side wall and the inner sidewall of stator yoke 11.Insulating surfaces 22 include several spaced insulating units, the quantity of insulating unit
And one-to-one correspondence identical as the quantity of circulation passage 3.The both ends of insulating unit are connect with upper surface 21 and lower end surface 23 respectively, often
Rib 221 is equipped on one insulating unit.
Fig. 1-Fig. 4 is please referred to, the present embodiment also provides a kind of stator, including insulation framework, stator core and winding (figure
In be not shown), stator core be stator core 1 described in any of the above embodiments.And insulation framework integrated injection molding is in stator core 1
On.
In the present embodiment, insulation framework is integrated injection molding, i.e., is put into injection mold after preheating stator core 1,
Insulation framework is directly molded on stator core 1.Compared to traditional split type insulation framework, the insulation bone of integrated injection molding
Frame, without insulating paper is arranged between insulation framework and stator core 1.Avoid what Split insulating skeleton insulating paper was easy to channel bit
Problem.The difficulty for the assembly that can also reduce, improves production efficiency.The insulation framework of integrated injection molding simultaneously, can be effective
Winding is improved around line mass, promotes copper factor.
In the case where injection molding quality is effectively ensured, the available preferable raising of the insulation quality of stator.Stator core
1, skeleton, winding fitting more closely, in the precompressed of mold, the stacking factor of stator core 1 obtains stator core 1
It improves, the two aspects are all conducive to improve motor noise quality.
The present embodiment also provides a kind of injection moulding process of insulation framework, comprising the following steps:
Insulation framework is molded upper surface 21 and the insulating surfaces 22 of insulation framework first, has been molded upper surface 21 and insulating surfaces 22
Afterwards, it is molded the lower end surface 23 of insulation framework, and lower end surface 23 is connect with insulating surfaces 22 far from the side of upper surface 21.
Referring to FIG. 4, since there are two end faces for insulation framework tool, when being molded, since the circulation of stator core 1 is logical
The mobility that road 3 is located at the injection molding material of the outlet port of downside can reduce (i.e. the injection molding material mobility of injection molding lower end surface reduces).
The injection molding that will lead to lower end surface is not full, generates faulty materials possibility and increases.To solve this problem, in this implementation, insulate bone
The injection moulding process of frame is divided into two steps.Firstly, being first molded the upper surface 21 of insulation framework and being molded the insulating surfaces 22 of insulation framework.To
When after being molded upper surface 21 and insulating surfaces 22, then being molded the lower end surface 23 of insulation framework, and being molded lower end surface 23, by lower end surface
23 are molded into an entirety far from the side of upper surface 21 with insulating surfaces 22, guarantee that the globality of insulation framework is good.Using upper
The method of stating is molded, and the injection molding difficulty of insulation framework can be greatly reduced, while can also provide the yields of injection molding, reduces wave
Take, reduces production cost.
Above description is merely a prefered embodiment of the utility model, is not intended to limit the utility model, for
For those skilled in the art, various modifications and changes may be made to the present invention.All spirit and original in the utility model
Within then, any modification, equivalent replacement, improvement and so on be should be included within the scope of protection of this utility model.
