Technical field
The utility model belongs to casting technology field, and in particular to a kind of cast system of independent control runner timing switching
System.
Background technology
In casting Technology Design, running gate system play a part of it is steady, efficient molten metal is imported into die cavity, its type and
Structure design is particularly important to casting quality.Wherein, in the step gating system of multilayer ingate up and down, molten metal
Die cavity is successively injected in layering from bottom to top, has the advantage of top pouring type, bottom filling concurrently, compensate for its each shortcoming.Staged is poured into a mould
It is steady and be conducive to casting consecutive solidification that system has the advantages that to fill type, thus has obtained in tall and big casting process widely should
With.
But, the structure of step gating system is more complicated, if design is improper, is easily sent out in the stowing operation of casting mold
Raw each layer running channel imports the phenomenon of molten metal simultaneously, causes molten metal mutually to collide, splash in die cavity, thus cause oxidation,
Be mingled with, sand holes and stomata.Especially in lost foam casting, air gap of the molten metal in EPS evaporative patterns in step gating system
Under jacking, casting mold is easily injected simultaneously by ingate up and down, the steady of liquid stream is destroyed, disturbs the gasification condition of apperance, it is many
Layer ingate declines.Thus step gating system is general in lost foam casting process does not advocate to use.
It can be seen that, the orderly importing die cavity of molten metal in multilayer, multiple ingates how is effectively realized, in being casting technique
One important difficult point.At present, to achieve the above object, the method used is sets each running channel size by complicated calculations, adopted
With unchoked running system, the technological measure such as distribution sprue need to be inclined upwardly for underfill state, upper strata running channel.These measures
Technological design difficulty is increased, the technique free degree is limited, product yield is reduced, and is still difficult to solve to pour in above-mentioned multilayer
Produced problem is applied in lost foam casting in road.
Utility model content
The purpose of this utility model is to provide that a kind of technique is simple, cost is low and effect is good, accurately independent control can pour
The control method of each runner timing switching in injection system, make each running channel of step gating system it is convenient, flexible realization layering, by
Layer injection effect, to solve the problem of above-mentioned prior art is not enough.The method is applicable not only to the staged cast system of different height
System, applies also for the timing controlled of filling type order of the control heavy castings to different parts.
To achieve the above object, the utility model is adopted the following technical scheme that：
Ingate and/or cross gate in a kind of running gate system of independent control runner timing switching, the running gate system
The spoiler of runner can be blocked completely by inside presetting, and the spoiler can melt broken in running channel under the high temperature action of potting syrup.
Preferably, the running gate system, including sprue cup, sprue and ingate, sprue couple sprue cup and interior
Running channel, it is characterised in that：The ingate is made up of along in short transverse upper strata ingate and bottom ingate, in the upper strata
Running channel at least includes presetting in one layer of ingate, the upper strata ingate that the choked flow of runner can be blocked completely along short transverse
Piece, and the spoiler can melt broken in inner flow passage under the high temperature action of potting syrup.
Preferably, the spoiler is flake structure, and its shape is with being blocked the shape of cross section of fluid channel identical, and its face
Product can completely obscured runner.
Preferably, the spoiler material is metal or metal-base composites.
Preferably, the metal ingredient in the spoiler material is simple metal or alloy, and its fusing point is less than casting pouring temperature
Degree, and after the spoiler fuses into casting, casting composition is remained within the scope of its trade mark Rational Composition.
Preferably, in the runner usage quantity of spoiler be equal to according to the runner opening time designed by casting technique and
Choose the ratio of integers of the predetermined molten broken time of spoiler.
The beneficial effects of the utility model are,
（1）The utility model technique is simple.Conventional step gating system will realize that down sprue layering introduces molten metal
Function, need to carry out the technological design of complexity.And the utility model to be not required to carry out complicated technology calculates can be more efficiently
Realize that the layering timing of different running channels is introduced；
（2）The utility model makes running channel design more freedom and flexibility.Conventional step gating system will realize down sprue point
Layer introduces molten metal function, and it is designed by more limitation.It need to be in be not filled with state, can not use closed such as to distribute sprue
Running gate system, levels ingate spacing, which need to be less than effective pressure head, upper strata ingate, need to tilt upward setting.And this practicality is new
Type is without any restrictions to Design of Runner System, and layering introducing, timing switching effect can be realized in all kinds of different running gate systems, is
Design of Runner System provides the bigger free degree and more rich function realization is possible, and cost is low, and effect is good, can be accurately independent
The timing switching of each runner makes the convenient, flexible realization layering of each running channel of step gating system, successively noted in control running gate system
Enter effect；And timing controlled of the control heavy castings to the casting sequence of different parts is applied also for, using effect is good, technique
Yield rate is high.
（3）In lost foam casting, molten metal is under EPS air gap jackings in step gating system, easily within up and down
Running channel injects casting mold simultaneously, destroys the steady of liquid stream, disturbs the gasification condition of apperance, multilayer ingate declines.Cause
And step gating system does not advocate typically to use in lost foam casting process.And the utility model causes staged cast system
System can be also applied in lost foam casting well, and each layer running channel can be prevented effectively from the stowing operation of casting mold because importing simultaneously
Molten metal and cause molten metal mutually to collide, splash in die cavity so that cause to aoxidize, be mingled with, the phenomenon hair of sand holes and stomata
It is raw, so as to drastically increase product yield.
