Abstract

The utility model discloses an arrange sediment exhaust die casting, including foundry goods and cinder ladle, wherein, the foundry goods has the runner, the cinder ladle communicates with the runner before locating the runner, the cinder ladle has the second grade runner, the potting syrup loops through the die cavity of second grade runner and runner packing foundry goods, forms the foundry goods. The utility model discloses simple structure can effectively improve the gas pocket state of the runner one end of foundry goods.

Description

A kind of deslagging is vented die casting

Technical field

The utility model belongs to die casting field, more particularly to a kind of deslagging exhaust die casting.

Background technology

Small-sized die casting easily produces shrinkage cavity and cavitations at casting section thickness.The deslagging exhaust of foundry goods is typically all arranged In the end away from cast gate and aluminium liquid range, be conducive to the discharge of cold liquid and gas in injection process.But, for cast gate one end The larger foundry goods of thickness, when potting syrup enters cast gate, because the direct injection of the without hindrance thing potting syrup in front is to foundry goods distalmost end, Most of potting syrup is clashed into both sides shunting after cavity wall, but also has sub-fraction aluminium liquid (injecting liquid in advance) to be folded at cast gate Staggered floor drives in the wrong direction and fills, and finally mixes whirlpool with the aluminium liquid persistently injected near cast gate, although have the supplement of final boost, but It is mingled with substantial amounts of gas and in advance cold liquid at cast gate in die cavity so as to have exceeded phenomenon during interior porosity.

Utility model content

The utility model provides a kind of deslagging and is vented die casting, to overcome the defect of prior art.

For achieving the above object, the utility model provides a kind of deslagging and is vented die casting, including foundry goods and cinder ladle；Wherein, Foundry goods has cast gate；Cinder ladle is connected before cast gate with cast gate；Cinder ladle has two grades of cast gates；Potting syrup passes sequentially through two grades and pours Mouth and cast gate fill the die cavity of foundry goods, form foundry goods.

Further, the utility model provides a kind of deslagging and is vented die casting, can also have the feature that：Wherein, slag Bag edge matches with cast gate.

Further, the utility model provides a kind of deslagging and is vented die casting, can also have the feature that：Wherein, two Level cast gate and cast gate are on the range of potting syrup.

Further, the utility model provides a kind of deslagging and is vented die casting, can also have the feature that：Wherein, two Width of the width of level cast gate less than cast gate.

Further, the utility model provides a kind of deslagging and is vented die casting, can also have the feature that：Wherein, slag Thickness of the thickness of bag less than the foundry goods of cast gate side.

Further, the utility model provides a kind of deslagging and is vented die casting, can also have the feature that：Wherein, pour The thickness of the foundry goods of mouth side is more than 7mm.

The beneficial effect of this patent is：The utility model provides a kind of deslagging and is vented die casting, sets at the cast gate of foundry goods Cinder ladle is put, cinder ladle is arranged along the length direction of cast gate, and cinder ladle has two grades of cast gates, in the filling process, potting syrup and gas are arranged Go out the die cavity of foundry goods, in entering cinder ladle, improve the stomata states of cast gate one end of foundry goods, improve foundry goods total quality.Additionally, two Level cast gate and cast gate on the range of potting syrup, make that potting syrup is linear to be incident in the die cavity of foundry goods.Additionally, two grades Less than the width of cast gate, can accelerate potting syrup injects speed to the width of cast gate.

Description of the drawings

Fig. 1 is the top view that a kind of deslagging is vented die casting；

Fig. 2 is the sectional front view that a kind of deslagging is vented die casting；

Fig. 3 is the enlarged drawing in I region in Fig. 2.

Specific embodiment

Specific embodiment of the present utility model is illustrated below in conjunction with accompanying drawing.

As Figure 1-3, the utility model provides a kind of deslagging and is vented die casting, including foundry goods 10 and cinder ladle 20.

Foundry goods 10 is by die cavity moulding by casting.Foundry goods 10 has cast gate 11, and potting syrup enters die cavity by cast gate 11, forms foundry goods 10.This deslagging exhaust structure is mainly used in the foundry goods of the thickness H more than 7mm of the foundry goods 10 of the side of cast gate 11.

Cinder ladle 20 is connected before the cast gate 11 outside die cavity with cast gate 11.Cinder ladle 20 matches with cast gate 11, such as Fig. 1 institutes Show, cast gate 11 is strip in this enforcement, correspondingly, cinder ladle 20 arranges along cast gate 11, in strip.Cinder ladle 20 has two grades of cast gates 21.Potting syrup passes sequentially through two grades of cast gates 21 and cast gate 11 fills the die cavity of foundry goods 10.

Wherein, two grades of cast gates 21 and cast gate 11 make that potting syrup is linear to be incident to casting on the range of potting syrup In the die cavity of part 10.In addition, width of the width of two grades of cast gates 21 less than cast gate 11, can accelerate potting syrup injects speed.

Thickness H of the thickness h of cinder ladle 20 less than the foundry goods 10 of the side of cast gate 11.

As shown in figure 3, during cast, as shown by arrows in FIG., potting syrup is successively by two grades of cast gates for the flow direction of potting syrup 21 and cast gate 11 inject in the die cavity of foundry goods 10, potting syrup first directly injection is then back to distalmost end, potting syrup and gas by In being gradually discharged to cinder ladle 20, improve the stomata states of the one end of cast gate 11.
