Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, a kind of commutator assembling mould, comprise middle cage plate 100 and location guide pin bushing 200, in this, cage plate 100 is square body, and this location guide pin bushing 200 is round tubular.
As Fig. 1, Fig. 2, Fig. 4, shown in Fig. 5, middle cage plate 100 offers four run through in cage plate 100 and pilot hole 110 for holding commutator, the line of centres of four pilot holes 110 forms a square, certainly, the quantity of this pilot hole 110 is arranged according to actual needs, can more than four, also four can be less than, the end face of middle cage plate 100 offers four counter sinks 111 corresponding and coaxial with pilot hole 110, the first locating platform 112 is formed between each counter sink 111 and corresponding pilot hole 110, this counter sink 111 madial wall is vertical with the first locating platform 112, as shown in Figure 3, in guide pin bushing 200 one end, location, radial depressions is formed with Plug Division 210 and second locating platform 220 vertical with Plug Division 210, Plug Division 210 grafting vertical with counter sink 111, add steadiness therebetween, described Plug Division 210 is positioned at counter sink 111 and Plug Division 210 is affixed on counter sink 111 madial wall, described Plug Division 210 is against on the first locating platform 112, under location guide pin bushing 200 is conducted oneself with dignity, described second locating platform 220 is affixed on middle cage plate 100 end face, second locating platform 220 adds stability when location guide pin bushing 200 is connected with middle cage plate 100, prevent location guide pin bushing 200 from rocking, when four location guide pin bushings 200 are arranged on middle cage plate 100 simultaneously, arbitrary neighborhood two is located guide pin bushing 200 and is affixed, so, under the barrier effect of adjacent positioned guide pin bushing 200, each location guide pin bushing 200 is stable in this both direction, add the relative stability of location guide pin bushing 200.
The utility model adopts said structure; total is made up of middle cage plate 100 and location guide pin bushing 200; location guide pin bushing 200 and the socket connection of middle cage plate 100; easy disassembly; location guide pin bushing 200 has good guide effect; make commutator blank can enter into pilot hole 110 easily, certain protective effect is played to commutator blank simultaneously, prevent commutator blank from damaging or produce deformation.
Total saves the accessories such as rebound, to save in assembling process commutator to rebound, then from rebound to the flow process of middle cage plate 100, Structure and energy is more simple, and commutator assembling, compacting and molding time are shorter, and commutator working (machining) efficiency is higher.
After saving rebound, the weight of a whole set of assembling mould alleviates greatly, alleviate working strength and the energy consumption of staff, also improve efficiency of assembling to a certain extent, meanwhile, the risk in assembling process reduces greatly,
In addition, total is optimized, and reduces or control the input of production cost to a certain extent, saves certain spending for producing.
Further, in order to increase the stability of location guide pin bushing 200, the end face of middle cage plate 100 is provided with eight corresponding to pilot hole 110 and the location notch 120 of locating piece (not shown) can be installed, the two ends of described location notch 120 are connected with middle cage plate frontside edge with pilot hole 110 respectively, a pilot hole 110 is equipped with two orthogonal location notchs 120, during assembling, in location notch 120, corresponding locating piece can be installed, the end of locating piece is against on the outer surface of location guide pin bushing 200, the setting of location notch 120, each location guide pin bushing 200 can be made to be located accordingly in mutual vertical both direction, under the effect of locating piece, four location guide pin bushings 200 are affixed all the time successively, add the stability of four location guide pin bushings 200, prevent it from rocking.
Further, four angles of middle cage plate 100 offer respectively one run through in cage plate 100 and location hole 130 for holding reference column (not shown), by this location hole 130, can middle cage plate 100 be installed on reference column, make middle cage plate 100 can vertically movement, after commutator is shaping, commutator is pushed down, by cage plate in movement 100, can make the commutator demoulding easily, herein, middle cage plate 100 is positioned on reference column also can realize automatic vertical lifting, so, the labour intensity of staff can also greatly be alleviated.
Further, the side outer wall of middle cage plate 100 is provided with bake pressure tracheae 140, four and the bake pressure cavity 150 that separate and the main cavities 151 that with four bake pressure cavities 150 are connected corresponding to pilot hole 110 are provided with in described middle cage plate 100, described bake pressure cavity 150 is positioned at around pilot hole 110, described main cavity 151 is communicated with bake pressure tracheae 140, by bake pressure cavity 150, the heat temperature raising to each pilot hole 110 can be realized, high-temperature gas is positioned at bake pressure cavity 150, heat not easily distributes, therefore, heat energy effect is higher, pilot hole 110 raises very fast and constant temperature continues more stable, commutator is heated more even, Forming Quality is higher.
In prior art, generally external heat is carried out, under the impact of ambient temperature to whole middle cage plate 100, the heating-up temperature of middle cage plate 100 is a greater impact, and heat easily distributes, and middle cage plate 100 heats up slower, be heated uneven, cause commutator shaping speed comparatively slow and commutator total quality is poor.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
