Embodiment
Below in conjunction with the accompanying drawings, specific embodiments of the present invention are described in detail.
As depicted in figs. 1 and 2, direct current generator magnetic shoe Shockproof rotor mould of the present invention, including lower mould 1 and therewith
Mould 3 on mould 2 and second on first coordinated, lower mould include bottom base 4 and are arranged on lower mold core moving up and down in bottom base 4
5, the upper surface of bottom base 4 is provided with the profile groove 6 suitable with rotor, the bottom up stretching of the upper end of lower mold core 5 from groove 6
And the outer iron core 7 in rotor is supported, it is fixed with fix bar 8 at the central axis of lower mold core 5, the upper end of fix bar 8 is from lower mold core 5
Upper end stretch out, fix bar 8 is suitable with the interior internal diameter of iron core 9 in rotor from the diameter of the external part of lower mold core 5, fix bar 8 stretch out under
The position of core rod 5 is provided with the shaft shoulder 10 for supporting interior iron core 9 in rotor, and mould 2 includes the first top base 11 on first, and first
The first flow 12 communicated with groove 6 is provided with top base 11, the first top base 11 is provided with the upper bottom surface point of respective grooves 6
Be not provided with first projection of circle 13, the outlet of first flow 12 positioned at the outside of the first projection 13, the first projection 13 respectively with outside
The upper surface of iron core 7 is bonded, and mould 3 includes the second top base 14 on second, and the bottom surface of the respective grooves 6 of the second top base 14 is set
Have second projection of circle 15, be provided with second flow channel 16 in the second top base 14, in the lower surface of the second projection 15 and rotor in
The upper surface of iron core 9 contacts, the second raised 15 inwalls, on the lower surface of the second top base 14, the upper surface of fix bar 8 and interior iron core 9
The Fig. 3 of branch chamber 17 1 is formed between surface, the outlet of second flow channel 16 communicates with branch chamber 17, the company of being provided with the second projection 15
The through hole 25 at the position of groove 6 outside the logical projection 15 of branch chamber 17 and second.
The lower section of bottom base 4 is provided with fixed seat 18, and cavity 19 is provided with fixed seat 18, is provided with cavity 19
The guide pad 20 of lower movement, guide pad 20 are connected with the lower end of fix bar 8, pass through between the bottom of guide pad 20 and fixed seat 18
Spring 21 is connected.Said structure can guarantee that fix bar 8 moves up and down automatically.
Some guide rods 24 moved up and down are provided with the bottom base 4, the lower surface of the first top base 11 is provided with
Some counterbores 22 corresponding with guide rod 24, the upper end of guide rod 21 are stretched into counterbore 22, the lower end of guide rod 24 and guide pad
20 fix, the distance between the upper surface of guide rod 24 and the upper surface of bottom base 4 be equal to the lower surface of outer iron core 7 and the bottom of groove 6 it
Between distance.The structure using the lower surface of mould 3 on second pushes guide rod 24 and so that fix bar 8 moves down, and can so keep away
Exempt from the second projection 15 and suppress interior iron core 9 to cause to damage move down fix bar 8, so as to influence rotor quality.
The external diameter of first projection 13 and the diameter of lower mold core 5 are respectively smaller than the maximum outside diameter of outer iron core 7, so outer iron
Core 7 just leaves the position that both ends of the surface contact with PBT, so can guarantee that magnetic shoe 23 and outer iron core 7 are smoothly fixed together.
When actual production, the lower quantity of mould 1 is formed a circle for 3 and mutual alignment can switch, on first
Mould 3 is separately fixed at the top of mould 1 under two of which on mould 2 and second, thus forms three stations, prepackage station, first
Station and second station, can continuously it work.It is exactly single one lower mould 1 to pre-install station, for operating personnel into groove 6
Be put into magnetic shoe 23, outer iron core 7 and interior iron core 9, the first station is made up of mould 2 on first and lower mould 1 below, second station by
Mould and lower mould 1 below form on second.First station is used to be molded engineering plastics, such as PBT (poly terephthalic acid fourths two
Alcohol ester), second station is used for injection molded elastomer.
As shown in Figure 4 and Figure 5, direct current generator magnetic shoe Shockproof rotor.The lower course of work of the invention is described in detail below, it is first
Magnetic shoe 23, outer iron core 7 and interior iron core 9 are well placed by first operating personnel as requested, then operate machine and lower mould 1 is moved into first
Station, i.e., the lower section of mould 2 on first, then mould 2 moves down lower surface and the upper end of die shoe 4 until the first top base 11 on first
Face is bonded a Fig. 1, and now, guide rod 24 is inserted in counterbore 22, and lower mold core 5 is in summit position under the indirectly-acting of spring 21
Put, the upper surface of lower mold core 5 supports outer iron core 7, and groove is divided into PBT to note by the first projection 13, outer iron core 7 and lower mold core 5
Region and rubber injection mold region are moulded, first flow 12 communicates with PBT injections region, as long as PBT material are passed through into the note of first flow 12
Enter in PBT injections region, just magnetic shoe 23 and outer iron core 7 are fixed together after waiting PBT material coolings.After the completion of injection, on
Mould 2 on first is moved, lower mould 1 is moved into second station, i.e., lower section-Fig. 2 of mould 3 on second, mould 3 on second are moved down, in the mistake moved down
Cheng Dangzhong, the lower surface of the second top base 14 can first touch the top of guide rod 24 and be directed to bar 24 and push, guide rod 24
Guide pad 20 is driven to move down, and guide pad 20 drives fix bar 8 and lower mold core 5 to move down together, until the second top base 14
Lower surface is bonded with the upper surface of die shoe 4, and now, the upper surface of lower mold core 5 departs from the upper surface of outer iron core 7, interior iron core 9
The position of technological requirement is moved in the presence of fix bar 8, rubber is then injected into groove 6 by second flow channel 16,
Rubber is by branch chamber 17 and through hole 25 full of the internal pore of groove 6 and final molding.Move up on second after mould 3, guide pad 20 exists
Resetted in the presence of spring 21, i.e., fix bar 8 and lower mold core 5 move up and the rotor of shaping ejected, and facilitate operating personnel
Take out rotor.It is an advantage of the invention that：Operating efficiency is high, once puts, effectively prevents the secondary error put and brought, from
