Abstract
The present invention is a kind of cast gate cup structure that can prevent molten iron from splashing out in casting, foundary industry must be entered when the molten iron of fusing pours into type chamber by sprue cup, general cone sprue cup is influenced and operator's qualification by iron flow or position, often in casting, molten iron splashes out sprue cup, the present invention designs a kind of rectangular sprue cup on DISA moulding line, semi-circular recesses are opened up outward in bottom of a cup portion edge, the molten iron for making molten iron not flow into down gate in casting expands into groove along bottom, by groove guiding role, molten iron is rolled-up inwardly to be splashed out again upwards, rather than it is splashed out outward upwardly along circular cone, stablize process when casting.
Description
Technical field
Casting mold sprue cup can prevent from splashing out the geometry of molten iron in foundary industry.
Background technique
Casting and molding method is tracked to quotient's week in the past in China, and such as the bronze ware that quotient's early stage in week is unearthed, ancients are already slapped
It holds and melts METAL HEATING PROCESS, then pour into mold, just become profile identical with mold after cooling.Wherein molten metal is fallen
When entering mold, mold must have an opening, be exactly that we are referred to as cast gate, and cast gate is generally cup-shaped, up big and down small, essentially
Circle pours into type chamber convenient for molten iron, in casting due to the changes in flow rate of molten iron and the variation of molten iron package location, is being poured
Shi Huiyou molten iron is splashed out to outside casting mold, and there are also the influence of operator's qualification, the spillage molten iron outside casting mold has been that the minister of public works in ancient china is shown in
Used phenomenon, the molten iron of spillage have been the part for accounting for suitable weight in foundry return.
Summary of the invention
The purpose of the present invention is being directed to the geometry of sprue cup, improvement is made, makes molten iron when pouring into sprue cup by cup
Interior geometry influences and is not easy a kind of structure splashed out.
The technical scheme is that sprue cup is changed to rectangular from cone, lower part is zoomed in but in bottom of a cup portion surrounding
Abducent semi-circular recesses again, then connected by intermediate openings with down gate.
Remarkable result of the invention be after this sprue cup improves on DISA moulding machine production line in application, molten iron casting
When first pour to sprue cup bottom, flow into down gate still there is extra molten iron to flow around, when stream splash to bottom edge into
Entering groove to be oriented to by grooved semicircular profile surface, molten iron is inwardly rolled again upwards by bottom, it still splashes in the middle part of sprue cup, rather than edge
Conical wall splashes out upwards, when casting molten iron splash out it is basic disappear, pour beam and stablize in cast gate and enter type.
Detailed description of the invention
Fig. 1 sprue cup cross-sectional view
1, casting mold 2, sprue cup chamber 3, guide groove 4, down gate
Specific embodiment
Sprue cup chamber 2 is offered at the top of casting mold 1, is surrounded by semicircle outside guiding in 2 bottom of sprue cup chamber
Slot 3,2 intermediate openings of sprue cup chamber are connected with down gate 4.
Claims (1)
1. the cast gate cup structure that one kind can prevent molten iron from splashing out in casting, it is characterized in that: being offered on casting mold top rectangular
Sprue cup chamber is provided with the guide groove of semi-circular recesses in sprue cup bottom of chamber portion edge outward, in the middle part of sprue cup chamber with casting
The connection of type down gate.
