Description
Technical field
The present invention relates to a kind of lead for retractable pencil plane.
Background technology
Three kinds of structures be present in lead for retractable pencil plane of the prior art.
The first is that single moulding is dug with cutter hub by screw lock formula lead for retractable pencil.Moulding forms screw, and cutter hub adds
Work has a connecting hole, coordinates the connecting hole of cutter hub and screw by screw during assembling and cutter hub is fixed on moulding.Lead for retractable pencil is dug
In use, screw easily produces loosening, after user's tightening screw again, is just not easy to ensure the cutting edge of cutter hub with going out
Plane where bits mouth is affixed and the cutting edge of cutter hub is placed in crumb mouth place plane and two phases of the taper surface of tapered pen-rolling hole
Between intersection, so as to cause lead for retractable pencil plane effect to be deteriorated, or even volume pen can not be carried out again, so that influence lead for retractable pencil plane uses the longevity
Life.
Second is that two mouldings are dug with cutter hub embedded locating type lead for retractable pencil.Cutter hub is directly embedded into a moulding and knife
After three faces of body are positioned, then the moulding is embedded in another moulding the fourth face of cutter hub is positioned, so as to ensure
The cutting edge of cutter hub is affixed with plane where crumb mouth and the cutting edge of cutter hub is placed in crumb mouth place plane and tapered pen-rolling hole
Between two intersecting lenses in tapered face, there could be a preferably volume effect.But due to easily existing between two mouldings
Error, so as to can not necessarily ensure that the cutting edge of cutter hub is placed in two of crumb mouth place plane and the tapered face of tapered pen-rolling hole
Between intersecting lens, so as to cause high percent defective.
The third is that injection molding type lead for retractable pencil is dug moulding simultaneously with cutter hub.The technical scheme, existing will to Workpiece Machining Accuracy
Ask high, the shortcomings that percent defective is high in process of producing product.Because cutter hub is a smaller and relatively thin component, in order to enter to cutter hub
The accurate positioning of row, its mold mechanism is complicated, although cutter hub corresponds to pen-rolling hole side and can obtained by pen-rolling hole building core
Preferably positioning, but cutter hub then needs to be positioned by larger workpiece with respect to pen-rolling hole opposite side, so as to have impact on lead for retractable pencil plane
To should position spacing wall area, and then have impact on lead for retractable pencil plane intensity so that influenceing its service life.
The content of the invention
In view of the deficienciess of the prior art, it is an object of the invention to provide one kind assembling is more convenient, yield rate is higher,
The volume lead for retractable pencil that pen is better, service life is longer plane.
To achieve the above object, the invention provides following technical scheme：A kind of lead for retractable pencil plane, including injection-moulded housing and knife
Body, the pen-rolling hole in coniform setting is provided with injection-moulded housing, pen-rolling hole side is provided with crumb mouth, and the crumb mouth is thereon

And the cutting edge of cutter hub is placed between two intersecting lenses of the taper surface of its plane of crumb mouth and the coniform pen-rolling hole, described
Injection-moulded housing is injection monomer, has the positioning chamber positioned to cutter hub in injection monomer, the positioning chamber corresponds to cutter hub
The both sides of width and the both sides of thickness direction are provided with spacing side wall, the both sides of the width of the cutter hub and
At least portion is affixed with corresponding spacing side wall for the both sides of thickness direction, and the positioning chamber corresponds to the length side of cutter hub
The opening for entering positioning chamber for cutter hub is provided with to one end.
By using above-mentioned technical proposal, during injection, the positioning chamber of monomer is molded by Workpiece shaping, and be molded positioning chamber
Workpiece in injection its intensity much larger than injection-moulded housing and cutter hub integrated injection molding cutter hub, thus reduce even without into
The workpiece opposite side of the relative shaping pen-rolling hole of the workpiece of type positioning chamber is positioned, while simplifying mold mechanism so that note
The positioning chamber for moulding monomer has larger spacing area spacing to cutter hub progress with respect to pen-rolling hole opposite side, so that cutter hub energy
Enough more stable is positioned in positioning chamber so that volume pen is better, service life is longer.During assembling, cutter hub is by opening
Can easily it be assembled into positioning chamber.
It is of the invention further to set：The positioning chamber of the injection monomer has the middle part of pen-rolling hole opposite side relative with cutter hub
The spacing side wall being at least partly affixed.
By using above-mentioned technical proposal, further such that the positioning chamber of injection monomer with respect to pen-rolling hole opposite side with compared with
Big spacing area cutter hub is carried out it is spacing so that being positioned in positioning chamber of can more stablize of cutter hub so that roll up pen
It is better, service life is longer.
It is of the invention further to set：The positioning chamber of the injection monomer has crumb mouth relative with the cutting edge of cutter hub opposite side
The limited wall being affixed.
, can be spacing to cutting edge progress by using above-mentioned technical proposal, further cutter hub is more stablized
Be positioned in positioning chamber.
It is of the invention further to set：The thickness direction of the corresponding cutter hub of the opening of the positioning chamber of the injection-moulded housing by it is interior extremely
Outer is in the setting that gradually broadens.
By using above-mentioned technical proposal, cutter hub more smoothly can load positioning chamber by opening during assembling.
It is of the invention further to set：The injection monomer is provided with inclined-plane, and the inclined-plane is placed in the positioning chamber and corresponds to knife
The limited wall corresponding opening direction side of body width side.
By using above-mentioned technical proposal, due to the effect on inclined-plane so that cutter hub can be more smoothly in positioning chamber
It is installed in place.
