Abstract
The utility model relates to a kind of riser buss to prevent the structure metal run out in sand mold, the magnitude of interference for having 0.5-1.5mm with external mold is made in the thickness on the end flange side of riser buss, the flight of 5 × 5mm together is made in riser buss inner hole and feeding a casting position cooperates, the position that the end and riser buss that riser is contacted with riser buss are contacted with external mold can prevent molten iron from leaking, really play the effect saved Langaloy molten iron, and improved riser feeding.
Description
Technical field
A kind of riser buss of the additional riser buss of foundary industry model technique feeding head is used for external mold cooperation precision raising
Prevent molten iron from the structure drained in outer die hole in gap.
Background technique
A kind of a kind of casting of turbocharger connection exhaust manifold of the BorgWarner Inc that our company accepts, material is height
53031016083 volute manifolds of nihard arrange two exhaust manifold volutes on one pair of Die and mould plate, share feeding head
Riser buss 18, using riser buss, riser cooling rate can be made to slow down, the feeding function of riser is reinforced, while can save treasured
Expensive nickelic molten iron.But when using riser buss, the cooperation of riser buss and external mold is easily in contact gap, when molten iron fills type
Molten iron can gap between riser buss and external mold leak out, flow to the space of external mold, cause the increase of nickelic molten iron usage amount.
Summary of the invention
The present invention is to improve riser buss and external mold contact position precision, using interference design size, casting mold is made to fill type
When, molten iron will not leak into outside riser buss.
Technical solution is that end face of flange is added in the end of riser buss, and flange thickness is interference fitted with external mold, and control exists
The magnitude of interference of 0.5-1.5mm, the flight step that flange internal orifice adds one 5 × 5 are connect with feeding a casting position, make riser buss
More one layer of sealing and anti-leakage structure between casting.
Improved remarkable result is the end that riser is contacted with riser buss and riser buss when filling type to sand mold and outer
The position of mould contact can prevent molten iron from leaking, and really play and saved Langaloy molten iron, and improve the effect of riser feeding
Fruit.
Detailed description of the invention
Fig. 1, improved riser buss sectional view.
Wherein: 1, riser buss 2, riser 3, external mold 4, riser buss flange 5, riser buss inner hole flight 6, casting
7, external mold 8, core model
Specific embodiment
4 thickness of end flange side and 3 magnitude of interference of external mold of riser buss 1 have 0.5-1.5mm, form 5 in 1 inner hole of riser buss
× 5 flight 5 cooperates with feeding a casting position, and after assembling riser buss 1, the molten iron of riser 2 does not have clearance leakage outside
3 space of mould is gone.
Claims (1)
1. a kind of riser buss prevents the structure metal run out in sand mold, it is characterised in that: the thickness system on the end flange side of riser buss
At the magnitude of interference for having 0.5-1.5mm with external mold, the flight of 5 × 5mm and feeding a casting position together is made in riser buss inner hole
Cooperation, after assembling riser buss, the molten iron of riser does not have from gap leaks out phenomenon outward.
