The one-step molding mould disclosed by the utility model can realize the one-step molding of the commutator hook, thereby improving production efficiency and reducing labor cost.

Description

One-shot forming die for commutator crotch
[technical field]
The utility model relates to a kind of commutator crotch mould.
[background technology]
In the prior art, the crotch moulding of commutator generally needs three to four procedures to accomplish, and production efficiency is low, and labour cost is high.
[summary of the invention]
In view of the deficiency of prior art, the technical problem that the utility model will solve is to be to provide a kind of can realize the one-time formed commutator crotch mould of commutator crotch.
The utility model is implemented through following technical scheme: one-shot forming die for commutator crotch; Comprise upper die and lower die; It is characterized in that: patrix includes cope match-plate pattern, punch, push rod and spring, and punch is fixed on the cope match-plate pattern, and the inboard shape of the die head shape of punch and the crotch of moulding commutator is coincide; Said push rod is actively installed in the nib of punch, and said spring is located at the bottom of push rod; Counterdie comprises lower bolster, die sleeve and core rod, and die sleeve is fixed on the lower bolster, and die sleeve has the nib of band awl mouth; The tapering of awl mouth is identical with the moulding angle of commutator crotch; Core rod is movable the setting in the nib of die sleeve, and the bottom of core rod is connected with elastomer, and the die orifice shape of core rod and the crotch back shape of moulding commutator are coincide; The anastomotic part of projection is outwards open and flat from the centre; The core rod end face is provided with the positioning head that the commutator endoporus is positioned, and after core rod, die sleeve were installed, the die orifice of core rod exposed to the nib of die sleeve.The top end of the head end coupling commutator of said push rod, and be provided with the positioning head that the commutator endoporus is positioned.
The commutator crotch mould of technique scheme can be realized the one-shot forming of commutator crotch, has improved production efficiency, has reduced labour cost.
[description of drawings]
Fig. 1 is the structural representation (before the action) of commutator crotch mould;
Fig. 2 is the structural representation (action back) of commutator crotch mould;
Fig. 3 is the commutator product design figure before the crotch moulding
Fig. 4 is the commutator product design figure after the crotch moulding
[embodiment]
As shown in the figure; This one-shot forming die for commutator crotch comprises upper die and lower die, and patrix includes cope match-plate pattern 1, punch 3, push rod 4 and spring 2; Punch 3 is fixed on the bottom of cope match-plate pattern 1; The die head 3a shape (outer centrum) of punch is coincide with inboard 13 shapes of the crotch of moulding commutator, and said push rod 4 is actively installed in the nib of punch 3, the top end 12 of the head end 4a of push rod coupling commutator; And being provided with the positioning head 4b that commutator endoporus 10 is positioned, said spring 2 is located at the bottom of push rod 4; Counterdie comprises lower bolster 7, die sleeve 6 and core rod 5, and die sleeve 6 is fixed on the end face of lower bolster 7, and die sleeve 6 has the nib of band awl mouthful 6a; The tapering of awl mouthful 6a is identical with the moulding angle A of commutator crotch; Core rod 5 is movable the setting in the nib of die sleeve 6, and the bottom of core rod 5 is connected with elastomer 8, and crotch back 14 shapes of the die orifice 5a shape of core rod and moulding commutator are coincide; The anastomotic part of projection is outside horizontal development from the centre; Core rod 5 end faces are provided with the positioning head 5b that commutator endoporus 10 is positioned, and after core rod, die sleeve were installed, the die orifice 5a of core rod exposed to the nib of die sleeve 6.
Above-mentioned commutator crotch mould is to realize that like this commutator crotch is one-time formed: as shown in Figure 1, the commutator product of Fig. 3 is placed on the core rod 5, and the positioning head 5b of core rod end face inserts commutator endoporus 10 and positions; Cope match-plate pattern 1 drive punch 3 moves downward then, and the positioning head 4b of push rod inserts the commutator endoporus, and push rod 4 begins to press down commutator; In the process of pressing down, push rod 4 compression springs 2, commutator gets in the nib of punch 3; Outwards bending is until 90 degree along the die orifice 5a of core rod in hook body segment 11 beginnings of commutator simultaneously, and then cope match-plate pattern 1 drives punch 3 and continues downwards, and punch 3 and push rod 4 are pushing away the elastic force that core rod 5 overcomes elastomer 8 and moving downward; So nib of the die orifice 5a indentation die sleeve 6 of core rod; Under the effect of nib awl mouthful 6a, the hook body segment 11 of commutator continues bending, until position as shown in Figure 2; The hook body segment moulding of commutator puts in place, and the commutator product after the crotch moulding is as shown in Figure 4.
