Description
Technical field
The present invention relates to a kind of fixed core with elastic stud, belong to casting technology field.
Background technology
At present, the use of the supporter of special shape is that stud is a kind of logical to core progress Auxiliary support in foundry engieering
The practice.The shape of stud is varied, and plane, circular arc, U-shaped etc., size is different in size, be according to stud
The shape of position, die cavity in casting, the wall thickness of casting select shape, the size of stud.But for group core is more, compartment is more,
Disconnected chamber, the complicated cavity product of disconnected outstanding core and wall thickness dimension, the accuracy of form and position require strict product, it is necessary to design and produce perhaps
The stud that Multiple Shape is different, size is different, some stud height great disparities are larger, needed for each stud also measures it with walk
Highly, workload is quite big, a prominent weak link as influence moulding, lower core efficiency.Therefore, it is badly in need of innovation a kind of
Widely used fixation core elasticity stud.
The content of the invention
The purpose of the present invention is exactly to overcome disadvantages described above there is provided a kind of elastic stud
The technical scheme is that, elastic stud, including upper blade and lower blade, and connect the company of upper blade and lower blade
Fitting, it is characterised in that：Described connector includes upper connecting rod and lower link, and the described upper blade of upper connecting rod connection is described
The lower blade of lower link connection, is connected between described upper connecting rod and lower link using elastomer block.
Further, the thickness of described upper blade and lower blade is 0.4-0.5mm.
The beneficial effects of the invention are as follows：Simplify the casting technique difficulty of product, reduce the complex process class of product,
Product size precision and the accuracy of form and position are improved, it is more superior particularly with the complicated casing in inner chamber and housing class product casting
Property；Solve the folding core of such product, float core the problems such as, improve the yield rate of such product；Improve production efficiency,
Production cost is reduced, the competitiveness of product in market is improved.
Brief description of the drawings
Fig. 1 is the structure sectional view of the present invention.
In figure, 1 elastomer block, 2 times blade, blade, 4 times connecting tubes, 5 upper connecting rods on 3.
Embodiment
Embodiment below in conjunction with the accompanying drawings, the present invention is further described.As illustrated, elastic stud, including the He of upper blade 3
Lower blade 2, and connect the connector of upper blade 3 and lower blade 2, upper blade 3 and the lower material therefor of blade 2 and casting material phase
Together, the fusing point of a little higher than casting metal of its fusing point, to ensure that it has enough strength support sand before casting does not solidify completely
Core, while fused well with casting in process of setting, surface is clean, oil-free, it is rustless, without aqueous vapor, preferably zinc-plated or plating
Strict pickling is wanted before tin, plating.Described connector includes upper connecting rod 5 and lower link 4, the described upper blade of the connection of upper connecting rod 5
3, the lower blade 2 of the described connection of lower link 4 is connected, described is upper between described upper connecting rod 5 and lower link 4 using elastomer block 1
The thickness of blade 3 and lower blade 2 is 0.4-0.5mm.
The beneficial effects of the invention are as follows：The casting technique difficulty for simplifying product, the complex process shelves for reducing product
It is secondary, product size precision and the accuracy of form and position are improved, it is more excellent particularly with the complicated casing in inner chamber and housing class product casting
More property；Solve the folding core of such product, float core the problems such as, improve the yield rate of such product；Improve production
Efficiency, production cost is reduced, improve the competitiveness of product in market.
