The utility model relates to a kind of molding die of rotor, including lower die and upper mold, the upper mold center opens up upper hole, and the upper mold lower end surface opens up upper end board slot, and the lower die upper end opens up lower end board slot, offers dead axle hole below the lower end board slot.The step of reducing production and processing, processing efficiency is improved while guaranteeing quality of rotor of motor, cost can also reduce.
Description
Technical field
The utility model relates to a kind of molding dies of rotor.
Background technique
Rotor includes machine shaft and rotor punching two parts, in the past in the process of processing rotor are as follows: first right
Insulating layer is done outside machine shaft, then rotor punching is arranged outside insulating layer, then again in the setting at rotor punching both ends
End plate, the main purpose of two end plates are exactly to move to limit rotor punching on machine shaft.
The method of previous this processing rotor, needs to complete the process in two steps, long processing time, production efficiency.
Utility model content
Technical problem to be solved by the utility model is: overcome the deficiencies of the prior art and provide a kind of rotor at
Pattern tool, solves the problems, such as to process rotor low efficiency in the past.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of molding die of rotor, packet
Lower die and upper mold are included, the upper mold center opens up upper hole, and upper mold, the upper mold lower end surface are run through in the upper hole up and down
Upper end board slot is opened up, upper hole lower end is connected to upper end board slot；
The lower die upper end opens up lower end board slot, and the dead axle for fixing machine shaft is offered below the lower end board slot
Lower die is run through in hole, the dead axle hole.
Further, the upper mold lower end surface opens up multiple upper location holes and the multiple upper positioning pins of setting, the lower die
Upper surface opens up multiple lower Positioning holes and the multiple lower positioning pins of setting.
The beneficial effects of the utility model are:
The step of rotor is poured to be formed, is reduced production and processing using the molding die of this practicability is guaranteeing electricity
Processing efficiency is improved while machine rotor quality, cost can also reduce.

Specific embodiment
The utility model is further described presently in connection with specific embodiment.These attached drawings are simplified schematic diagram
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
As shown in Figures 1 to 6, a kind of molding die of rotor, including lower die 2 and upper mold 1,1 center of upper mold open up
Upper mold 1 is run through in upper hole, upper hole up and down, and 1 lower end surface of upper mold opens up upper end board slot, upper hole lower end and upper end board slot
Connection.
2 upper end of lower die opens up lower end board slot 2A, and the dead axle hole for fixing machine shaft 3 is offered below the board slot 2A of lower end
2B, the dead axle hole 2B run through lower die 2.
1 lower end surface of upper mold opens up 3 upper location holes and setting 3 upper positioning pins, and 2 upper surface of lower die opens up 3
3 lower positioning pin 2C of lower Positioning holes and setting.
When upper mold 1 and lower die 2 carry out molding operation, in the upper location hole of the lower positioning pin 2C insertion upper mold 1 of lower die 2,
In the lower Positioning holes of the upper positioning pin insertion lower die 2 of upper mold 1, for guaranteeing that upper mold 1 and lower die 2 are in the same center line, protect
Demonstrate,prove the injection molding quality to two baffles upper and lower in rotor and internal insulating layer.
A kind of processing method of rotor, using above-mentioned molding die；The following steps are included:
S1,3 lower end of machine shaft is inserted into the 2B of dead axle hole, is kept fixed machine shaft 3；Machine shaft 3 and dead axle
There are certain outlet gaps between the 2B of hole, for guaranteeing that fluid can smoothly enter into casting region in injection moulding process.
S2, rotor punching 4 is shelved on to 2 upper surface of lower die, shape between 4 lower end surface of rotor punching and lower end board slot 2A
Chamber is poured at bottom plate 6；
Machine shaft 3 is passed through from the axis hole of rotor punching 4, and insulation is formed between the machine shaft 3 and shaft hole inner wall
Layer casting chamber；Bottom plate 6 is poured between chamber and insulating layer casting chamber and is connected to；
S3, upper mold 1 is placed on to 4 upper end of rotor punching, 3 upper end of machine shaft is protruded into 1 upper hole of upper mold, institute
It states and forms the casting chamber of upper head plate 5 between 4 upper end of rotor punching and upper end board slot.Upper head plate 5 is poured chamber and is connected to upper hole；
S4, casting liquid is injected from upper hole, casting liquid sequentially enters upper head plate 5 and is poured chamber, insulating layer casting chamber
And bottom plate 6 is poured chamber, takes out rotor after solidification to be cooled.During molding, 3 upper fixed for upper mold 1 and lower die 2
Position pin and 3 lower positioning pin 2C are passed through from the 6 of rotor punching 4 winding slots respectively, and positioning pin, which plays, plays rotor punching 4
The effect of positioning, so that it is guaranteed that machine shaft 3 and the axis hole of rotor punching 4 are concentric, it is ensured that the insulating layer quality being poured.
Material used in being poured in the utility model is BMC composite material；
The molding die of the utility model, for insulating layer, overhead gage, the lower baffle plate in disposal pouring rotor,
Forming die structure is reliable and stable, provides guarantee for pouring practice.
The utility model realizes to insulating layer, overhead gage, lower baffle plate one in rotor the processing method of rotor
Body casting complete reduces procedure of processing, improves production efficiency, reduces manufacturing cost.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
