The invention discloses a stator insulation plastic coating die which is small in plastic coating deformation. The stator insulation plastic coating die comprises a lower die body and an upper die body, the lower die body comprises a mold core and a base, the base is provided with at least two sliding blocks moving in the radial direction, and a cavity for stator plastic coating is formed among the lower surface of the upper die body, the inner walls of the sliding blocks, the upper surface of the lower die body and the outer wall of the mold core; inclined through holes are formed in the sliding blocks, an inclined guide column is arranged on the upper die body, and the lower end of the inclined guide column extends into the inclined through hole of the corresponding sliding block and enables the corresponding sliding block to move in the direction getting close to the mold core in the radial direction; and the upper die body is further provided with a locking device for locking the sliding blocks after the sliding blocks are in place. The stator insulation plastic coating die has the beneficial effects that the sliding blocks are opened before injection molding, a stator is conveniently placed into the cavity, and therefore the accuracy is improved; and during injection molding, the sliding blocks are locked, the stator can be shaped, the circular degree of the stator reaches the requirement, the accuracy of the inner circle and the outer circle of the stator is improved, and vibration and noise of a motor are reduced.
Description
Technical field
The present invention relates to a kind of plastic mould of stator insulation.
Background technology
Plastic the referring to of stator insulation is injected partly plastic on stator thus is realized the insulation of stator. The structure of the plastic mould of original stator insulation is for comprising upper die and lower die, counterdie is made up of type core and base, a plastic cavity of stator it is provided with between patrix, type core and base, this structure produce plastic after stator can be out of shape after taking-up, distortion at 0.3 ~ 0.5mm, the use of stator can be produced a very large impact by this, such as noise is big, and stator is not easy to put into cavity, tolerance clearance is little, and production efficiency is low.
Summary of the invention
Technical problem to be solved by this invention is: provide the plastic mould of stator insulation that the plastic distortion of a kind of stator is little.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of plastic mould of stator insulation, comprise counterdie and patrix, described counterdie comprises type core and base, base is provided with at least 2 slide blocks moved radially, the plastic cavity of stator is formed between the upper surface of the lower surface of patrix, the inwall of slide block, counterdie and the outer wall of type core, slide block is respectively arranged with oblique through hole, being provided with side draw pin on patrix, the lower end of side draw pin stretches in the oblique through hole of corresponding slide block and slide block is radially moved near type core.
Patrix is also provided with respectively slide block is locked dead locking latches after slide block puts in place, described locking latches comprises the latch segment being fixed on counterdie lower surface, the radial outside wall of slide block tilt and angle of inclination identical with the angle of oblique through hole, the sidewall of latch segment also tilts and outer side wall with slide block is close to. The sidewall of described latch segment arranges block rubber.
The spring of level it is respectively arranged with between described slide block and base.
The push rod that stator is ejected cavity it is provided with in described base.
The invention has the beneficial effects as follows: injection moulding front-slider is opened, cavity conveniently put into by stator, it is to increase precision, and during injection moulding, slide block lock is dead, can shaping stator so that it is circularity reaches requirement, it is to increase stator inside and outside circle precision.

In figure: 1, counterdie, 2, patrix, 3, type core, 4, base, 5, slide block, 6, cavity, 7, tiltedly through hole, 8, side draw pin, 9, latch segment, 10, spring, 11, push rod, 12, block rubber.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the invention scheme is described in detail.
As shown in Figure 1, the plastic mould of stator insulation of the present invention, comprise counterdie 1 and patrix 2, described counterdie 1 comprises type core 3 and base 4, base 4 is provided with at least 2 slide blocks moved radially 5, 4 slide blocks 5 can be set when actual production, the lower surface of patrix 2, the inwall of slide block 5, the plastic cavity of stator 6 is formed between the upper surface of counterdie 1 and the outer wall of type core 3, slide block 5 is respectively arranged with oblique through hole 7, patrix 2 is provided with side draw pin 8, the lower end of side draw pin 8 stretches in the oblique through hole 7 of corresponding slide block 5 and slide block 5 is radially moved near type core 3, patrix 2 is also provided with after slide block 5 puts in place, respectively slide block 5 is locked dead locking latches.
Locking latches can adopt following simple structure, described locking latches comprises the latch segment 9 being fixed on counterdie 1 lower surface, the radial outside wall of slide block 5 tilt and angle of inclination identical with the angle of oblique through hole 7, the sidewall of latch segment 9 also tilts and outer side wall with slide block 5 is close to. The advantage of this structure is, in counterdie 1 folding process, side draw pin 8 first inserts oblique through hole 7 and promotes slide block 5 to move to center respectively, and after mobile end, slide block 5 is just locked by latch segment 9, very convenient. In order to make locking effect more obvious, it is possible to arrange block rubber 12 on the sidewall of latch segment 9. When reality uses, it is also possible to screw withstands slide block 5 to realize the locking of slide block 5 from horizontal direction, and the method needs operator to operate in addition.
In order to ensure when not working, the oblique through hole 7 of slide block 5 is directed at side draw pin 8, is respectively arranged with the spring 10 of level between described slide block 5 and base 4. One end and the base 4 of spring 10 are fixed, and the other end and slide block 5 are fixed.
In order to facilitate stator to take out, in described base 4, it is provided with the push rod 11 that stator is ejected cavity 6.
It is an advantage of the invention that: in the industry, no one can expect adopting slide block structure, and original structure is very ripe. Injection moulding front-slider is opened, and cavity conveniently put into by stator, it is to increase precision, during injection moulding, slide block lock is dead, and slide block also plays the effect of shaping stator while the effect playing sizing, this critical function, directly cause plastic after the distortion amount of stator, it is that the technician of this area fails to give attention to, makes stator roundness of external circle reach requirement, it is to increase stator inside and outside circle precision, produce plastic after stator deformability amount < 0.2mm, can effectively reduce motor vibrations and noise.
