Description

One kind casting dead head shear
Technical field
The present invention relates to automobile decoration technical field, and in particular to one kind casting dead head shear.
Background technology
Dead head refers to avoid casting from the supplement part that defect is attached to above casting or side occur.In casting mold In, the die cavity of dead head is the container for storing liquid metal, and its function is many.The different rising head of function is its form, big It is small and open up position and differ, so, the characteristics of design of dead head will consider the property and casting of casting alloy.Pour and emit Mouth is act as:1st, for the little alloy of volume contraction in process of setting (such as gray cast iron), or the conjunction of concentrating shrinkage cavity is not produced Gold(Such as tin bronze), the effect of dead head, which mainly discharges the gas in die cavity and collects Flowage frontage, is mixed with field trash or oxidation The molten metal of film, to reduce the defects of casting.2nd, for require control microscopic structure casting, dead head can be with collection liquid The molten metal that stream forward position has cooled down, avoids occurring over-cooling structure on casting.3rd, it is big for volume shrinkage mass between freezing period and become To in the alloy for forming concentrating shrinkage cavity(Such as cast steel, manganese brass and aluminium bronze), the main function of dead head is compensation molten metal The contraction in liquid contraction and casting solidification process in die cavity, to obtain the sound casting of no shrinkage cavity.
After casting completion, dead head will be removed, in some existing removal technologies, if using artificial If removal, cost is big and removal is not accurate, wastes time and energy, operating efficiency is low.Also there are some shears for being directed to dead head, But it is often insecure in the presence of fixation, occur the phenomenon offset in shear history, cause shearing not accurate, while device occur With inflexible phenomenon.
