Abstract
Commutator plastic sheath peel of mould disclosed by the invention, including activity upper mold and fixing lower mold, it is characterized in that: thimble is installed in the bottom of activity upper mold, the diameter of thimble head is less than plastic sheath diameter of bore, fixing lower mold includes upper padding plate and the lower bolster of fixing connection, upper padding plate is provided with the upper through hole allowing diverter and plastic sheath assembly simultaneously pass through, upper through-hole diameter is more than plastic sheath outside diameter, lower bolster be provided with allow diverter separately through lower through-hole, the diameter of lower through-hole more than commutator cylindrical diameter less than plastic sheath outside diameter.The present invention separates with plastic sheath after being exclusively used in diverter injection mo(u)lding, improves efficiency, reduces labor intensity, the most important thing is to realize simultaneously plastic sheath again with.
Description
Technical field
The present invention relates to a kind of mould, be specifically related to a kind of be exclusively used in diverter injection mo(u)lding after the mould that separates with plastic sheath.
Background technology
In the manufacturing process of diverter, first the blocks of independent copper segment of punching, then copper segment is carried out in plastic sheath screening, then the commutator segment after screening is put in diverter compression moulding die together with plastic sheath and jointly carries out injection mo(u)lding with phenolic moulding powder or other matrix material, the diverter being molded and plastic sheath are strong bonded, the method used at present is to utilize cutter to be cut off by the cylindrical of plastic sheath, then from commutator cylindrical surface, it is carried out peeled off diverter to separate with plastic sheath, efficiency is low, labor intensity is big, most important plastic sheath destroyed and can not obtain again with.
Summary of the invention
In view of the deficiencies in the prior art, the technical problem to be solved in the present invention be to provide a kind of be exclusively used in diverter injection mo(u)lding after separate with plastic sheath, improve efficiency, reduce labor intensity, the most important thing is to realize simultaneously plastic sheath again with commutator plastic sheath peel of mould.
The present invention implements by the following technical programs:
Commutator plastic sheath peel of mould, including activity upper mold and fixing lower mold, it is characterized in that: thimble is installed in the bottom of activity upper mold, the diameter of thimble head is less than plastic sheath diameter of bore, fixing lower mold includes upper padding plate and the lower bolster of fixing connection, upper padding plate is provided with the upper through hole allowing diverter and plastic sheath assembly simultaneously pass through, upper through-hole diameter is more than plastic sheath outside diameter, lower bolster be provided with allow diverter separately through lower through-hole, the diameter of lower through-hole more than commutator cylindrical diameter less than plastic sheath outside diameter.
After using technique scheme, as long as commutator plastic sheath assembly injection completed (the also non-demoulding in mould bucket) is put into above upper padding plate with mould bucket, then activity upper mold is utilized to drive thimble to move down, just by thimble, commutator plastic sheath assembly down can be ejected in mould bucket, simultaneously carry out being automatically separated of diverter and plastic sheath after work completes ejecting, the diverter finally completing separation drops out from the bottom of fixing lower mold, plastic sheath then can be removed in staying fixing lower mold intactly, not only realize being automatically separated of diverter and plastic sheath, improve efficiency, reduce labor intensity, and plastic sheath remains intact, be capable of plastic sheath again with.
Mask work for making commutator plastic sheath is reliable and stable to be carried out, and the technical scheme is that described thimble head has the curved surface coincideing with diverter upper surface shape and is provided with the inserted link for diverter Internal hole positioning.
As preferably, being provided with guide pillar and guide between activity upper mold and fixing lower mold, guide pillar is fixed in activity upper mold, and fixing lower mold is provided with corresponding pilot hole.Above-mentioned design not only makes the relative motion between activity upper mold and fixing lower mold reliably be guided, and when the mould bucket of built-in commutator plastic sheath assembly is put into above upper padding plate, the aliging of the pilot hole of mould bucket and guide pillar also can make the upper through hole accurate alignment of the workpiece in mould bucket and upper padding plate, it is ensured that mask work is accurately carried out.
Accompanying drawing explanation
The present invention has the following drawings:
Fig. 1 is state diagram when being promoted in mould bucket of the commutator plastic sheath assembly of the present invention；
Fig. 2 is that the commutator plastic sheath assembly of the present invention begins preparing for state diagram when separating；
Fig. 3 is the state diagram after the commutator plastic sheath assembly separation of the present invention.
Detailed description of the invention
nullAs shown in the figure，The commutator plastic sheath peel of mould of the present invention，Including activity upper mold 1 and fixing lower mold，Thimble 3 is installed in the bottom of activity upper mold 1，The diameter of thimble 3 head is less than plastic sheath 5 diameter of bore，Described thimble 3 head has the curved surface coincideing with diverter 6 upper surface shape and is provided with the inserted link 4 for diverter 6 Internal hole positioning，Fixing lower mold includes upper padding plate 8 and the lower bolster 9 of fixing connection，Upper padding plate 8 is provided with the upper through hole 11 allowing diverter 6 and plastic sheath 5 assembly simultaneously pass through，Upper through hole 11 diameter is more than plastic sheath 5 outside diameter，Lower bolster 9 be provided with allow diverter 6 separately through lower through-hole 12，The diameter of lower through-hole 12 is less than plastic sheath 5 outside diameter more than diverter 6 outside diameter，Upper lower through-hole is coaxially disposed，It is provided with guide pillar 2 between activity upper mold 1 and fixing lower mold to guide，Guide pillar 2 is fixed in activity upper mold 1，Fixing lower mold is provided with corresponding pilot hole 10，Mould bucket 7 also is provided with corresponding pilot hole.
The present invention is so work: the diverter 6 and plastic sheath 5 assembly that injection are completed are put into above upper padding plate 8 with mould bucket 7, then activity upper mold 1 is utilized to drive thimble 3 to move down, first commutator plastic sheath assembly is down ejected in upper through hole 11 in mould bucket 7 by thimble 3, when commutator plastic sheath assembly arrives lower through-hole 12 upper port position, plastic sheath 5 is blocked by lower through-hole 12 and can not continue to move down, and diverter 6 continues to move down under the promotion of thimble 3, then diverter 6 and plastic sheath 5 realize being automatically separated, diverter 6 after separation drops out from the bottom of lower through-hole 12, plastic sheath 5 then can be stayed in through hole 11 intactly, it is removed Deng after moving on thimble 3 and taking mould bucket 7 away, plastic sheath 5 can obtain again with.
