Abstract
The utility model discloses a kind of hard alloy shunting nozzle, inner chamber position shape face is sub- minute surface, and inner chamber is minute surface, and streamline line is runner rift grain；Along small round corner transition at profile step；Tip top face be minute surface, knife-edge part round-corner transition, all step end face perpendicularity in 0.01mm, the hard alloy shunting nozzle inside and outside surface be provided with coating.Hard alloy shunting nozzle of the present utility model compared to conventional products service life extend 58 times and more than, shorten each single molding cycle time, lift the synthesis output efficiency of injection molding product, runner is smooth smooth, without cleaning, shunting is quick, contributes to the finished appearance effect of portioned product.
Description
Technical field
The utility model belongs to mold injection field, more particularly to a kind of hard alloy shunting nozzle.
Background technology
The shunting nozzle of conventional hot flow path application is generally beryllium copper, the material such as stainless steel.It is easy to wear during its use, change
It hurry up, cost is high, efficiency is low, and uniformity and the required precision of influence shaped article, it is mainly shown as：
1, cavity shape is complicated, can not be directly perceived, and processing capacity is big.
2, all luminal wall surfaces require that minute surface can be only achieved optimal runner effect.
3, profile roots Level bears HTHP easy fracture in operation.
4, in injection moulding process, shunting nozzle tip is easy to wear, bursts apart, bending.Cause shaped article stability poor, quality is not
It is good, or even scrap.
The content of the invention
The purpose of this utility model is to provide a kind of hard alloy shunting nozzle, it is intended to which solving conventional shunting nozzle, it was used
It is easy to wear in journey, change fast, cost is high, efficiency is low, the problem of influenceing uniformity and the required precision of shaped article.
The utility model is achieved in that a kind of hard alloy shunting nozzle, and the hard alloy shunting nozzle is provided with：
Inner chamber；
Step is marked with the outside of the inner chamber；
The front end of the inner chamber is marked with tip；
The edge of a knife is in the end of inner chamber, the lower section positioned at tip.
Further, the inner chamber, step, tip, edge of a knife integrated injection moulding.
Further, using the inner chamber of sub- minute surface.
Further, the inner chamber streamline line is runner rift grain.
Further, the step end face perpendicularity is less than 0.01mm.
Further, the hard alloy shunting nozzle inside and outside surface scribbles coating.
Hard alloy shunting nozzle of the present utility model compared to conventional products service life extend 5-8 times and more than, shorten often
Individual single molding cycle time, lifts the synthesis output efficiency of injection molding product, and runner is smooth smooth, without cleaning, shunting
Quickly, the finished appearance effect of portioned product is contributed to.
Brief description of the drawings
The structural representation for the hard alloy shunting nozzle that Fig. 1 provides for the utility model embodiment.
The left view for the hard alloy shunting nozzle that Fig. 2 provides for the utility model embodiment.
In figure：1st, inner chamber；2nd, step；3rd, it is sophisticated；4th, the edge of a knife.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain this practicality
It is new, it is not used to limit the utility model.
Structure of the present utility model is explained in detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the hard alloy shunting nozzle that the utility model embodiment is provided includes：Inner chamber 1, step 2,
Tip 3, the edge of a knife 4.
The outside of inner chamber 1 is marked with step 2；The front end of inner chamber 1 is marked with tip 3；The edge of a knife 4 is in the end of inner chamber 1, positioned at tip
3 lower section.
The hard alloy shunting nozzle that the utility model embodiment is provided, is made using following methods：
Technology is molded using hard alloy, anticorrosive, wear-resistant, high temperature resistant is added for injection raw material and hot environment,
The metallic elements such as thermal conductivity factor height, make the shunting nozzle crude green body of reserved size.
Inner chamber position shape face is accomplished by sub- minute surface with resin instrument；
Fluid polishing is carried out to inner chamber and causes minute surface, streamline line is runner rift grain；
It will do trickle along R transition at profile step, and carry out mirror surface treatment, to increase stress resistance energy；
Ensure that all step end face perpendicularity in 0.01mm, to prevent combined stress from concentrating at not flat spot, cause to break
Split；
Tip top does mirror plane processing, and knife-edge part does micro- R transition processings, does inside and outside to injection special substance shunting nozzle
Portion's surface coated treatment.
Hard alloy shunting nozzle of the present utility model compared to conventional products service life extend 5-8 times and more than, shorten often
Individual single molding cycle time, lifts the synthesis output efficiency of injection molding product, and runner is smooth smooth, without cleaning, shunting
Quickly, the finished appearance effect of portioned product is contributed to.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
