Abstract
The utility model is related to a kind of rotation Leave out thread injection molding cover with positioning backing stop structure, and the injection is covered with rotation Leave out thread, and the nearly bottom ending segment of described rotation Leave out thread is broken end screw thread, and the broken end screw thread extension is provided with retaining stuck point.Compared with prior art, the utility model has the advantages that simple structure, the scope of application are not limited, to position stopping function more stable.
Description
Technical field
The utility model is related to a kind of rotation Leave out thread injection molding cover, more particularly, to a kind of de- spiral shell of the rotation with positioning backing stop structure
Line injection molding cover.
Background technology
The existing injection molding cover that backing stop structure is positioned in screw thread ending segment band, cannot typically be made by revolving Leave out thread mould
Make；The injection molding cover of usual this structure using the mould of oblique top thread-relieving mechanism, or can use the mould of strong thread-relieving mechanism
To make.The mould of oblique top thread-relieving mechanism cannot be applied on injection molding cover of the diameter less than 25mm；The mould of strong thread-relieving mechanism
Tool is limited to plastic cement elastic physical property in itself, it is impossible to make the enough positioning backing stop structures of intensity, in actual applications, spiral shell is taken off by force
The positioning backing stop structure that line structure mold is made is easy to failure, does not have the effect of positioning.
Utility model content
The purpose of this utility model be exactly provided for the defect for overcoming above-mentioned prior art to exist a kind of simple structure,
The scope of application is not limited, positions the rotation Leave out thread injection molding cover that the more stable band of stopping function positions backing stop structure.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of rotation Leave out thread injection molding cover with positioning backing stop structure, the injection is covered with rotation Leave out thread, the de- spiral shell of described rotation
The nearly bottom ending segment of line is broken end screw thread, and the broken end screw thread extension is provided with retaining stuck point.
Described retaining stuck point is located at the thin-walled Hookean region of injection cap body, and its thickness is other region wall thickness of lid
50%-60%.
Described thin-walled Hookean region is by gradual change chamfered transition to other wall thickness regions.
The entrance angle on described gradual change inclined-plane is 120 degree.
The scope of described thin-walled Hookean region is the 1/6~1/7 of whole injection molding cover circumference.
Described retaining stuck point is highly higher than injection molding cover core diameter of thread 0.3mm~0.5mm.
Described retaining stuck point to the screw thread ending segment that breaks end is provided with connected boss.
Described boss is less than 0.1~0.3mm of retaining stuck point.
Described retaining stuck point is with broken end screw thread ending segment distance for 1~1.5 times of ridge is wide.
Described injection molding cover is the lid that PE polyethylene material or PP polypropylene materials are made.
Compared with prior art, the utility model has advantages below：
1) product structure is simple, it is possible to use the Mold Making of rotation thread-relieving mechanism.
2) it is applied widely, go for the injection molding cover of various sizes scope.
3) positioning retaining point intensity is higher, can fully ensure that injection molding cover positions the function of retaining.

Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is a part of embodiment of the present utility model, rather than whole implementations
Example.Based on the embodiment in the utility model, those of ordinary skill in the art institute on the premise of creative work is not made
The every other embodiment for obtaining, should all belong to the scope of the utility model protection.
As shown in figures 1-4, rotation Leave out thread injection molding cover of the present utility model, mainly sets to described retaining stuck point 1
Meter.Higher than the injection molding cover core diameter of thread about 0.3mm~0.5mm, it designs and causes retaining stuck point the height of retaining stuck point 1 that design is included
The elasticity of region is better than other regions of injection molding cover.In moulding at the end of injection moulding process, mould is de- from moulding inside
During going out, when rotation Leave out thread core rotated back is by retaining stuck point, the thin-walled Hookean region where retaining stuck point can be sent out
The certain elastic deformation of life so that rotation Leave out thread core can smoothly slip over retaining stuck point, until exiting moulding completely.
The thickness of wall thickness 5 of the thin-walled Hookean region 6 where retaining stuck point 1 is designed as the 50%-60% of normal areas wall thickness；
Thin-walled Hookean region 6 is transitioned into common wall thickness regions by gradual change inclined-plane 7, and the entrance angle on gradual change inclined-plane 7 is 120 °；Thin-walled elasticity
The thin-walled scope in region 6 is the 1/6~1/7 of whole part circumference；Retaining stuck point 1 to the broken end ending segment of screw thread 2 is designed with connected
Boss, boss height 3 is slightly below retaining 0.1~0.3mm of stuck point, the slightly above core diameter of thread.Land length 4 is apart from being 1~1.5
Ridge again is wide.
Retaining stuck point 1 described in the utility model when thread core is passed through, the thin-walled Hookean region 6 where retaining stuck point 1
Generation elastic deformation, thread core smoothly slips over retaining stuck point 1.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any one skilled in the art can readily occur in various in the technical scope that the utility model is disclosed
Equivalent modification or replacement, these modifications or replacement should all be covered within protection domain of the present utility model.Therefore, this practicality
New protection domain should be defined by scope of the claims.
