Abstract
The disclosed commutator plastic sheath peel of mould of the utility model, comprise movable patrix and fixing counterdie, it is characterized in that: thimble is installed in the bottom of movable patrix, the diameter of thimble head is less than plastic sheath diameter of bore, fixedly counterdie comprises upper padding plate and the lower bolster being fixedly connected with, upper padding plate is provided with the upper through hole that allows commutator and plastic sheath assembly simultaneously pass through, upper through-hole diameter is greater than plastic sheath outside diameter, lower bolster is provided with the lower through-hole that allows commutator pass through separately, and the diameter of lower through-hole is greater than commutator cylindrical diameter and is less than plastic sheath outside diameter.The utility model is exclusively used in after commutator injection mo(u)lding separated with plastic sheath, raises the efficiency, and reduces labor intensity, and the most important thing is to realize the utilization again of plastic sheath simultaneously.
Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of mould separated with plastic sheath after commutator injection mo(u)lding that be exclusively used in.
Background technology
In the manufacturing process of commutator, conventionally first punching slices copper segment independently, then copper segment is carried out in plastic sheath to screening, then the commutator segment after screening is put in commutator compression moulding die and jointly carries out injection mo(u)lding with phenolic moulding powder or other matrix material together with plastic sheath, the commutator that injection moulding completes and plastic sheath are strong bonded, the method adopting is at present to utilize cutter that the cylindrical of plastic sheath is cut off, then it has been peeled off to the separated of commutator and plastic sheath from commutator cylindrical surface, efficiency is low, labour intensity is large, most important plastic sheath is destroyed and can not again be utilized.
Summary of the invention
In view of the deficiencies in the prior art, the technical problems to be solved in the utility model is to be to provide a kind of separated with plastic sheath of being exclusively used in after commutator injection mo(u)lding, raise the efficiency, reduce labor intensity, the most important thing is to realize the commutator plastic sheath peel of mould again utilizing of plastic sheath simultaneously.
The utility model is implemented by the following technical programs:
Commutator plastic sheath peel of mould, comprise movable patrix and fixing counterdie, it is characterized in that: thimble is installed in the bottom of movable patrix, the diameter of thimble head is less than plastic sheath diameter of bore, fixedly counterdie comprises upper padding plate and the lower bolster being fixedly connected with, upper padding plate is provided with the upper through hole that allows commutator and plastic sheath assembly simultaneously pass through, upper through-hole diameter is greater than plastic sheath outside diameter, lower bolster is provided with the lower through-hole that allows commutator pass through separately, and the diameter of lower through-hole is greater than commutator cylindrical diameter and is less than plastic sheath outside diameter.
Adopt after technique scheme, as long as the commutator plastic sheath assembly (the also not demoulding in mould bucket) that injection moulding is completed is put into above upper padding plate with mould bucket, then utilization activity patrix drives thimble to move down, just can commutator plastic sheath assembly down be ejected in mould bucket by thimble, after completing, the work of ejecting carries out the automatic separated of commutator and plastic sheath simultaneously, finally completing separated commutator drops out from the fixing bottom of counterdie, plastic sheath can be stayed intactly fixedly and be removed in counterdie, not only realize the automatically separated of commutator and plastic sheath, raise the efficiency, reduce labor intensity, and plastic sheath remains intact, can realize the utilization again of plastic sheath.
For making reliable and stable the carrying out of mask work of commutator plastic sheath, the technical scheme of employing is: described thimble head has the curved surface identical with commutator upper surface shape and is provided with the inserted link for commutator Internal hole positioning.
As preferably, movable patrix and be fixedly provided with guide pillar between counterdie and lead, guide pillar is fixed on movable patrix, and fixedly counterdie is provided with corresponding pilot hole.Above-mentioned design not only make movable patrix and fixedly the relative motion between counterdie reliably led, and when the mould bucket of built-in commutator plastic sheath assembly is put into above upper padding plate, the pilot hole of mould bucket also can make the workpiece in mould bucket accurately align with the upper through hole of upper padding plate with aliging of guide pillar, guarantees that mask work accurately carries out.
accompanying drawing explanation]
The utility model has the following drawings:
Fig. 1 is the state diagram of commutator plastic sheath assembly of the present utility model while being pushed in mould bucket;
Fig. 2 is the state diagram of commutator plastic sheath assembly of the present utility model while starting to prepare separation;
Fig. 3 is the state diagram after commutator plastic sheath assembly of the present utility model separation.
The specific embodiment
As shown in the figure, commutator plastic sheath peel of mould of the present utility model, comprise movable patrix 1 and fixing counterdie, thimble 3 is installed in the bottom of movable patrix 1, the diameter of thimble 3 heads is less than plastic sheath 5 diameter of bores, described thimble 3 heads have the curved surface identical with commutator 6 upper surface shapes and are provided with the inserted link 4 for commutator 6 Internal hole positionings, fixedly counterdie comprises upper padding plate 8 and the lower bolster 9 being fixedly connected with, upper padding plate 8 is provided with the upper through hole 11 that allows commutator 6 and plastic sheath 5 assemblys simultaneously pass through, upper through hole 11 diameters are greater than plastic sheath 5 outside diameters, lower bolster 9 is provided with the lower through-hole 12 that allows commutator 6 pass through separately, the diameter of lower through-hole 12 is greater than commutator 6 outside diameters and is less than plastic sheath 5 outside diameters, upper lower through-hole coaxially arranges, movable patrix 1 and be fixedly provided with guide pillar 2 between counterdie and lead, guide pillar 2 is fixed on movable patrix 1, fixedly counterdie is provided with corresponding pilot hole 10, mould bucket 7 is also provided with corresponding pilot hole.
The utility model is like this work: the commutator 6 that injection moulding is completed and plastic sheath 5 assemblys with mould bucket 7 be put into upper padding plate 8 above, then utilization activity patrix 1 drives thimble 3 to move down, first thimble 3 down ejects commutator plastic sheath assembly in through hole 11 in mould bucket 7, when commutator plastic sheath assembly arrives lower through-hole 12 upper port position, plastic sheath 5 is blocked and can not continue to move down by lower through-hole 12, and commutator 6 continues to move down under the promotion of thimble 3, so commutator 6 is realized automatically separated with plastic sheath 5, commutator 6 after separation drops out from the bottom of lower through-hole 12, plastic sheath 5 can be stayed in through hole 11 intactly, after moving and take away mould bucket 7 on thimble 3, be removed, plastic sheath 5 can access again and utilize.
