Abstract
The utility model discloses a kind of mold needle hot flow path bush assemblies, including needle and hot flow path bushing；The needle includes needle column, needle cap and needle end, and the diameter of the needle end is less than the diameter of needle column, an intermediate incline is provided between needle column；The needle end coated has wearing layer；The hot flow path bushing integral hollow, is provided with the through-hole with needle matching ends.The needle hot flow path bush assembly of mold involved in the utility model, there is a titanium as wearing layer in needle end coated, it increases needle end original wearability and also adds hardness, so that during producing pipetting tip, the abrasion of needle end and hot flow path bushing is reduced, service life is increased, the generation of substandard products is reduced.
Description
Technical field
The utility model relates to technical field of mold, especially a kind of mold needle hot flow path bush assembly.
Background technique
During using mold production components, the hot flow path bushing using needle and be used in combination with needle.
In use, needle end and through-hole, which exist, rubs, and will appear mill using meeting needle end and hot flow path bushing for a long time
Damage can make pipetting tip the phenomenon of flash occur, product produced is so that the spacing of needle and hot flow path bushing increases
Substandard products.
Utility model content
The purpose of the utility model is to provide a kind of mold needle hot flow path bush assemblies, increase in needle end
Wearing layer, so that the abrasion of needle end is reduced.
In order to solve the above technical problems, purpose of the utility model is realized as follows:
A kind of mold needle hot flow path bush assembly involved in the utility model, including needle and hot flow path bushing；
The needle includes needle column, needle cap and needle end, and the diameter of the needle end is less than the diameter of needle column, with
An intermediate incline is provided between needle column；The needle end coated has wearing layer；In the hot flow path bushing entirety
Sky is provided with the through-hole with needle matching ends.
As a further illustration of the above scheme, the hot flow path bushing includes bush body, liner cap and bushing
End；Annular projection is provided in the bush body；The outer edge of the liner cap includes straightway and segmental arc；Institute
The through-hole stated is located at gasket end.
As a further illustration of the above scheme, the wearing layer is titanium.
The beneficial effects of the utility model are: the needle hot flow path bush assembly of mold involved in the utility model,
Needle end coated has a titanium as wearing layer, that is, increases needle end original wearability and also add hardness, so that producing
During being molded components, the abrasion of needle end and hot flow path bushing is reduced, and is increased service life, is reduced substandard products
It generates.

Specific embodiment
The present invention will be further described in the following with reference to the drawings and specific embodiments.
In conjunction with Fig. 1 to Fig. 5, the utility model is explained in detail.A kind of mold needle involved in the utility model
Hot flow path bush assembly, including needle and hot flow path bushing.
Needle 1 includes needle column 11, needle cap 12 and needle end 13.The diameter of needle end 13 is less than needle column 11
An intermediate incline 14 is provided between diameter, with needle column 11, needle end 13 is coated with wearing layer.Hot flow path bushing 2 is whole
It is hollow, it is provided with the through-hole 24 matched with needle end 13.Wearing layer is titanium in the present embodiment.Titanium not only makes
The wearability for obtaining needle end increases, and also increases its hardness.So that needle end exists with the through-hole in hot flow path bushing
Abrasion in production process is reduced, and is reduced using the flash phenomenon of product.
Hot flow path bushing 2 includes bush body 21, liner cap 22 and gasket end 23.Bush body 21 is cylindrical in shape,
Cyclic annular convex 25 are provided on outside for mutually fixing with other component when in use.Through-hole 24 is located at gasket end 23.Bushing
End 23 is in inverted cone cell, is connected by an angled transition section with bush body 21.The top of gasket end 23 is provided with
One tubular protrusion, through-hole 24 is through tubular protrusion.
The outer edge of liner cap 22 includes straightway 26 and segmental arc 27.In the present embodiment, straightway 26 and segmental arc
27 each four sections, the length of straightway 26 can be identical, also can not be identical, needs match determination according to other components.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, it all should be within the scope of protection determined by the claims.
