Abstract
The present invention relates to the running gate system of a kind of automobile steering device tubular shell die casting, this running gate system is made up of sprue, cross gate, circular gate and Exhausting System four part, circular gate is the feeder connection that molten metal enters between cross gate rear end and foundry goods before housing die cavity, circular gate is connected with cross gate, and cross gate is connected with sprue; End filled by foundry goods is Exhausting System. The present invention can be effectively improved casting quality and mold use life-span.
Description
Technical field
The present invention relates to die-casting die casting system technical field, refer specifically to the running gate system of a kind of automobile steering device tubular shell die casting.
Background technology
Generally, automobile steering device tubular shell die casting adopts fan-shaped running gate system, namely it is filled with sector form to both sides by foundry goods center outside foundry goods tube wall, this kind of filling mode makes Shen Qiang position, pipe fitting two ends, it is easy to the defects such as volume gas, slag inclusion and shrinkage cavity shrinkage porosity and molten metal direct impingement core in cavity filling process occur, cause mandrel temperatures gradient bigger, it is easily generated heat exhaustion and the overheated easy generation sticking to mould of core, reduces the core life-span.
Summary of the invention
Goal of the invention
The present invention provides a kind of automobile steering device tubular shell die casting running gate system, its object is to effectively reduce the defects such as position, foundry goods deep chamber volume gas, slag inclusion and shrinkage cavity shrinkage porosity, improves quality of die casting, concurrently facilitate and improve die life.
Technical scheme
The present invention is achieved through the following technical solutions:
A kind of running gate system of automobile steering device tubular shell die casting, it is characterized in that: this running gate system is made up of sprue, cross gate, circular gate and Exhausting System four part, circular gate is the feeder connection that molten metal enters between cross gate rear end and foundry goods before housing die cavity, circular gate is connected with cross gate, and cross gate is connected with sprue; End filled by foundry goods is Exhausting System, and it is made up of block overflow launder and annular overflow trough; It is provided with three on the upside of tubular shell foundry goods and connects extraneous the first block overflow launder as exhaust apparatus respectively, one second block overflow launder it is provided with on the downside of tubular shell foundry goods, tubular shell foundry goods upper end is provided with first annular overflow launder, and tubular shell foundry goods end is provided with the second annular overflow trough.
The block overflow launder of on the upside of tubular shell foundry goods three first is arranged along tube wall distribution.
First annular overflow launder is made up of the three of decile arcuation overflow launders.
Second annular overflow trough is made up of the two of decile arcuation overflow launders.
Advantage and effect
The invention have the advantages that and beneficial effect:
It is an advantage of the present invention that choosing circular gate fills so that fill type steady; Meanwhile, the slag inclusion of molten metal front end can enter annular overflow trough smoothly, and on the upside of foundry goods, overflow launder may be used for deslagging and aerofluxus, and the effect of annular overflow trough decile is to prevent from liquid level forward position gas in cavity filling process from interfering to form defect hence into foundry goods. On the downside of foundry goods, overflow launder may be used for deslagging and prevents molten metal from rolling up gas at deep chamber place, improves casting quality and die life with this.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further:
The present invention is the running gate system of a kind of automobile steering device tubular shell die casting, as depicted in figs. 1 and 2: this running gate system is made up of sprue 1, cross gate 2, circular gate 3 and Exhausting System four part, circular gate 3 is the feeder connection that molten metal enters between cross gate 2 rear end and foundry goods before housing die cavity, it may be achieved molten metal conformal is steadily filled; The flow direction after molten metal entrance die cavity, speed and pressure are all had a great impact by the position of ingate, direction, size, therefore, adopt circular gate 3 to fill to fill type steady, it is simple to casting forming; Simultaneously, the gas of molten metal front end and slag inclusion can enter annular overflow trough smoothly, on the upside of foundry goods, block overflow launder may be used for deslagging and aerofluxus, and downside bulk overflow launder may be used for deslagging and prevents molten metal from rolling up gas at deep chamber place, improves casting quality and die life with this. Circular gate 3 is connected with cross gate 2, and cross gate 2 is connected with sprue 1; End filled by foundry goods is Exhausting System, for preventing from die-castingmold filling process occurring pore, shrinkage cavity and shrinkage porosite, aoxidizing the defects such as assorted slag, Exhausting System has been carried out rational optimization, Exhausting System is made up of block overflow launder and annular overflow trough, respectively the first block block overflow launder 5 of overflow launder 4, second, first annular overflow launder 6 and the second annular overflow trough 7; It is provided with three on the upside of tubular shell foundry goods and connects extraneous the first block overflow launder 4 as exhaust apparatus respectively, one second block overflow launder 5 it is provided with on the downside of tubular shell foundry goods, may be used for deslagging and prevent molten metal from rolling up gas at deep chamber place, casting quality and die life is improved with this, tubular shell foundry goods upper end is provided with first annular overflow launder 6, tubular shell foundry goods end is provided with the second annular overflow trough 7, for the gas collecting the oxide slag inclusion depositing molten metal front end and inside is not got rid of in time.
The block overflow launder 4 of on the upside of tubular shell foundry goods three first is arranged along tube wall distribution, and the first block overflow launder 4 is connected formation with extraneous exhaust apparatus and concentrates aerofluxus, for quickly getting rid of the gas within die cavity.
First annular overflow launder 6 is made up of the three of decile arcuation overflow launders.
Second annular overflow trough 7 is made up of the two of decile arcuation overflow launders.
The effect of annular overflow trough decile is to prevent from liquid level forward position gas in cavity filling process from interfering to form defect hence into foundry goods.
Conclusion, the present invention adopts circular gate and annular overflow trough, make the molten metal can conformal Stable Filling, simultaneously the gas of molten metal front end and slag inclusion can enter annular overflow trough smoothly, on the upside of foundry goods, overflow launder may be used for deslagging and aerofluxus, downside overflow launder may be used for deslagging and prevents molten metal from rolling up gas at deep chamber place, improves casting quality with this, improves die life.
