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 Auxiliary support is carried out to core is a kind of logical to stud 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, compartment many for group core be more,
The strict product of disconnected chamber, the complicated cavity product of disconnected outstanding core and wall thickness dimension, accuracy of form and position requirement, it is necessary to design and produce perhaps
The stud that Multiple Shape is different, size is different, some studs height great disparity is 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 fixed 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 the company for connecting 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, and described upper connecting rod is provided with spiral shell
Line.
Further, the thickness of described upper blade and lower blade is 0.4-0.5mm.
The beneficial effects of the invention are as follows：The casting technique difficulty for simplifying product, the complex process class for reducing product,
Product size precision and the accuracy of form and position are improve, it is more superior particularly with the complicated casing in inner chamber and housing class product casting
Property；Solve such product folding core, 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 improve.
Brief description of the drawings
Fig. 1 is structure sectional view of the invention.
In figure, 1 elastomer block, 2 times blade, blade, 4 times connecting tubes, 5 upper connecting rods, 6 screw threads on 3.
Specific 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
Tin, wants strict pickling before 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 between described upper connecting rod 5 and lower link 4 using elastomer block 1, and described is upper
Connecting rod 5 is provided with screw thread 6, and described upper blade 3 and the thickness of lower blade 2 are 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 improve, it is more excellent particularly with the complicated casing in inner chamber and housing class product casting
More property；Solve such product folding core, 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.
