Abstract
The utility model discloses a kind of three-point fix fuse composite insulator injection abrasive article structures, comprise die cavity, described die cavity is provided with multiple full skirt grooves of single full skirt groove and the horizontally set longitudinally arranged, plug is provided with in the described full skirt groove longitudinally arranged, be respectively equipped with the middle hardware and end metal fitting that crimp with plug and be connected in the middle part of described plug with end, described middle hardware is connected with die cavity by bolt with end metal fitting.The utility model has makes plug semi-finished product and die cavity no-float, reduces mould-type, reduces the feature of die cost, can be widely used in electric power electric field.
Description
Technical field
The utility model relates to electric power electric product, particularly relates to a kind of three-point fix fuse composite insulator injection abrasive article structures.
Background technology
Fuse is a kind of overcurrent protective device, during use, is series in protected circuit by fuse, plays the effect of protection.
Fuse composite insulator is in injection process, and the length of plug must strictly control, otherwise the plug semi-finished product crimped will be caused cannot to be placed in mould for injecting full skirt.Plug semi-finished product, only in Measurement Allowance, just can be stuck on mould and crimp.Fuse is divided into multiple electric pressure such as 15kV, 27kV, 38kV, and kind is relatively many, and existing mould is difficult to because adapting to this change regulate, and causes location constant, causes Product Precision lower.
Utility model content
The purpose of this utility model is the deficiency in order to overcome above-mentioned background technology, provides a kind of three-point fix fuse composite insulator to inject abrasive article structures, has and make plug semi-finished product and die cavity no-float, reduce mould-type, reduce the feature of die cost.
A kind of three-point fix fuse composite insulator injection abrasive article structures that the utility model provides, comprise die cavity, described die cavity is provided with multiple full skirt grooves of single full skirt groove and the horizontally set longitudinally arranged, plug is provided with in the described full skirt groove longitudinally arranged, be respectively equipped with the middle hardware and end metal fitting that crimp with plug and be connected in the middle part of described plug with end, described middle hardware is connected with die cavity by bolt with end metal fitting.
In technique scheme, described bolt is socketed with wedge shape sleeve.
The utility model three-point fix fuse composite insulator injection abrasive article structures, have following beneficial effect: end metal fitting, middle hardware once crimp with plug, crimping leading section gold utensil and middle hardware can take out easily and efficiently with the putting position of plug and the semi-finished product after crimping.Half-finished length is controlled preferably.Product is when injecting, and the length in die cavity is certain, and semi-finished product can be stuck in the groove of die cavity in the margin of tolerance, and its length of the amount of avoiding is lost time, and improves efficiency.
Die cavity is according to end metal fitting and middle hardware, and the shape of injection umbrella is determined, so more can ensure the qualification of every product.Die cavity also divides in order to three kinds of moulds according to the kind of fuse.
Bolt is fixed in wedge shape sleeve.When semi-finished product position is fixed by bolt, move axially wedge shape sleeve along bolt, just can fix bolt.
The semi-finished product crimped put into the injection mold cavities of three-point fix, be fixed, inject by bolt and wedge shape sleeve, to be injected complete after, exit wedge shape sleeve, desirable go out product, take three-point fix to inject, can effectively prevent product at die cavity intrinsic displacement.
The utility model has makes plug semi-finished product and die cavity no-float, reduces mould-type, reduces the feature of die cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model three-point fix fuse composite insulator injection abrasive article structures.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
See Fig. 1, the utility model three-point fix fuse composite insulator injection abrasive article structures, comprise die cavity 1, described die cavity 1 is provided with multiple full skirt grooves 2 of single full skirt the groove 2 and horizontally set longitudinally arranged, plug 6 is provided with in the described full skirt groove 2 longitudinally arranged, be respectively equipped with the middle hardware 5 and end metal fitting 4 that crimp with plug 6 and be connected in the middle part of described plug 6 with end, described middle hardware 5 is connected with die cavity 1 by bolt 7 with end metal fitting 4.Described bolt 7 is socketed with wedge shape sleeve 8.
By technological requirement adjustment injection device, first mould is cleared up mold exterior before installing, and checks that whether mold exterior accessory is complete, wants timely polishing to the accessory lacked.
Levelness and the perpendicularity of demoulding block in the middle of mould must be adjusted after mould is in place, prevent from damaging mould during die trial.
Manually slowly open mould, by technological requirement adjustment gum-injecting port or injecting glue position.Die holder is upper and lower die holder structure, and upper bolster is furnished with positioning guide column, and die shoe is furnished with location hole.Two ends and middle hardware are provided with three-point fix system.Length tolerance adopts one end directly to contact cooperation with die holder, uses screw mandrel spiral positioning above operative position, and silk tooth adopts rectangle tooth.The semi-finished product that gold utensil and plug crimp are put into the full skirt groove 2 above die cavity 1, adopt the mode of hydraulic pressure to carry out upper and lower mould pressurization.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
The content be not described in detail in this specification belongs to the known prior art of professional and technical personnel in the field.
