Description

A kind of lairage mold for commutator compression moulding process

Technical field

The utility model belongs to commutator production technical field, is pressed into specifically, it is related to one kind for commutator The lairage mold of type process.

Background technique

With the development of the society, motor is widely applied in the fields such as industrial production and family, public place, commutator is made For one in motor and the part of carbon brush cooperating and an important part of motor.

Currently, commutator production and processing mode is broadly divided into insert type, roll bending type (copper sheet type) with three kinds of full-plastic.Three kinds The each have their own advantage of processing method and deficiency.The process route of the production and processing of the insert type commutator is: copper material extruding → Drawing → rushing commutator segment → vibration washing → (rushing mica sheet) → screening → compression moulding → solidification → bore hole → is returned outside hole → vehicle Hook foot → milling lower quarter → milling hook foot → crotch molding → polishing → inspection in circle boring.And compression moulding is broadly divided into lairage, product Compression moulding demoulds three big steps.

Referring to Figure 12, it is directed to the lairage of insert type commutator at present, is broadly divided into the following steps: the piece circle that will be sequenced first 5 successively drive in the transitional pore 71 of transition plates 7 (remove piece circle outer circle on rubber band), successively knock out plastic core, then incited somebody to action Cage plate 8 is positioned by guide post in cab apron 7 and original, puts lairage upper mold 6, and the piece circle in transition plates 7 is passed through on press and lairage Jacking block 61 on mould 6 is pressed into original under the original of cage plate 8 in plate hole 81.Lairage upper mold 6 and transition plates 7 are removed, cage plate in original is taken out 8, cage plate 8 in the original with copper sheet is transferred to next step product compression moulding process.Therefore, existing lairage mode, process compared with It is more, low efficiency, labor intensity of workers height (die shape is big, heavier-weight), during piece circle is secondly knocked in transition plates 7, Because not being oriented to, completely with worker's feel and experience, copper material easily strikes bad, leads to scrap of the product, yield rate is low, therefore to worker's skill Art is more demanding.

Utility model content

The main purpose of the utility model is that for compression moulding process labor intensity of workers height, process is more, quality is low, The problems such as low efficiency, provides a kind of lairage mold for commutator compression moulding process.

A kind of lairage mold for commutator compression moulding process, including upper mold 1, middle mould 2, lower die 3 and middle cage plate 4, The upper mold 1, middle mould 2 and lower die 3 divide upper, middle and lower-ranking to arrange.

A upper mold guide rail 12 is separately connected at left and right sides of the downside of the upper mold 1, this two pieces upper mold guide rail 12 it is upper Guide-track groove is installed with relative direction, and the middle cage plate 4 is inserted in the upper rail slot, if the middle cage plate 4 is equipped with array Dry molding hole 42.

The middle mould 2 be equipped with several lairage mandrils 22 corresponding with molding hole 42 and four guide posts 26, it is described into The upper end for enclosing mandril 22 is installed by one iron core 21, pocketed springs 25 in the guide post 26.

A lower die guide rail 32 is separately connected at left and right sides of the upside of the lower die 3, under this two pieces lower die guide rail 32 Guide-track groove is installed with relative direction, and the middle mould 2 is inserted in the lower guideway slot.

In use, several piece circles 5 are set on the iron core 21, the modeling in piece circle 5 is ejected by iron core 21 Expect core 51, several the columnar copper sheets 52 that are combined on piece circle 5 are inserted in iron core 21 by the dovetails 521 on copper sheet 52 On, the mandril of press machine applies downward pressure from top to the upper plane of upper mold 1, and upper mold 1 is led to together with middle 4 downlink of cage plate It crosses guide post 26 to be positioned, is combined into columnar copper sheet 52 and enters molding hole 42, the mandril of press machine resets, and spring 25 pushes up Middle cage plate 4 out, extraction are transferred to next procedure with the middle cage plate 4 of copper sheet 52.

It is as follows to further limit technical solution:

The upper mold 1 further includes upper mould fixed plate 11, two upper polished rods 13 and overhead gage 14, the two pieces upper mold guide rail 12 Upper rail slot in a upper polished rod 13 is installed respectively, the back end surface of the two pieces upper mold guide rail 12 connects overhead gage 14.

The middle mould 2 further includes fixed plate 23 and bottom plate 24, and the fixed plate 23 is equipped with corresponding with lairage mandril 22 232, four threaded holes 233 of mandril fixation hole 231, four lower guide post location holes and two location holes 234, the mandril fixation hole 231 cooperate with 22 lower end of lairage mandril, and the guide post location hole 232 cooperates with 26 lower end of guide post, and the fixed plate 23 utilizes Positioning pin and screw pass through four threaded holes 233 respectively and two location holes 234 are connect with bottom plate 24, the width of the bottom plate 24 Size is greater than the width dimensions of fixed plate 23, so that forming slideway step at left and right sides of fixed plate 23, the slideway step is inserted in In lower guideway slot.

The middle cage plate 4 further includes two pieces handle 43, and the two pieces handle 43 is installed in parallel in the leading flank of middle cage plate 4, Middle cage plate 4 is promoted or is taken out from upper mold guide rail 12 using handle 43 by operator；Upper guide post is fixed there are four setting on the middle cage plate 4 Position hole 41, the upper guide post location hole 41 are clearance fit with 26 upper end of guide post.

The lairage mandril 22 is up-small and down-big three-level Step Shaft, and the upper end of lairage mandril 22 is upper cylinder 221, upper circle The coaxially connected middle cylinder 222 in the downside of column 221, the 222 coaxially connected lower cylinder 223 in downside of middle cylinder cover on the upper cylinder 221 Iron core 21 is filled, the iron core 21 is identical as 51 structure of plastic core.

The outer circle of the plastic core 51 is equipped with several vertical dovetail grooves 512, and the center of plastic core 51 is equipped with center Hole 511, the dovetail groove 512 cooperate with dovetails 521, and the centre bore 511 cooperates with upper cylinder 221.
