Description
Technical field
Foundry engieering is the utility model is related to, particularly a kind of casting dead head structure.
Background technology
In existing casting technique, casting rising head typically all uses cameron core, and the setting of this cameron core can realize use
Mechanical hammering method remove feeders, reduce cleaning rising head workload；Avoid cutting localized crackses caused by casting pressing port root and
Casting loses flesh phenomenon；The thermal center for reducing rising head root is also helped, improves mechanical performance, reduces cutting area.But cameron core
Setting there is also many shortcomings, as cameron core as independent auxiliary need to increase extra cost, also deposited in specific production process
In carrying, installation, swabbing etc. extra assignment；Because cameron core is because yielding in high temperature sintering or self-control, and and casting
Contact surface is larger perfect identical with casting face so as to cause to be not easy, and molding sand is not easy consolidation at the cylindrical reversed cone angle of cameron core, and casting needs
Extra polishing because cameron core misfit caused by fleshiness part；Cameron core part is mainly refractory or high temperature resistance super
After kind sand, the easy moisture absorption and binding agent are influenceed by molten steel heat, easily get angry and produce gas hole defect；Because of its reasons in structure, cameron core
Size only uses in the range of certain size, and flowing through the molten steel of cameron core can cause to heat very little insufficient, make cameron core position
Freeze ahead of time, do not have feeding（Passage）Effect, and large scale rising head causes pitch cutting to be soaked because of long-time because not solidifying for a long time
Bubble softening transform in molten steel does not have due effect；Also cameron core must upper and lower surface be heated will not just freeze ahead of time,
It can so cause rising head and casting contact site big, easily form contact thermal center, fall into generation contracting vacancy at casting thermal center.
The content of the invention
The purpose of this utility model is to solve problem above, there is provided it is a kind of reasonable in design, simplified operating procedure,
There is the casting dead head structure of preferable matching surface with casting.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：One kind carries necking down
The casting dead head structure of cameron core, including heating sleeve, it is characterized in that the rising head hypomere in described heating sleeve is up big and down small
Taper hole, heating sleeve are provided with necking part with casting body contacts position；Rising head bottom eck in necking part is provided with cameron core body,
Described cameron core body is up-small and down-big conical bore.Feeding problem is one of key problem of casting Technology Design, and correct
Judge and determine that casting is to solve the problems, such as feeding acquisition situations such as the position of thermal center, size, shape and quantity in process of setting
Perfect one of premise of sound casting, wherein dead head structure is also the major reason for influenceing the factor.Thermal center (hotspot) be
In process of setting, the temperature of localized metallic is high compared with environment temperature in casting mold, thus solidifies slow node or region.The technical program
In thermal center region, the function that the cameron core in existing structure is realized is fused to rising head bottom, directly in heating sleeve and casting
Part body contacts position is designed, that is, forms a kind of riser heating set of necking part with cameron core, and its heating sleeve is overall in itself
Made using high temperature resistant heat preservation material, be independent damp-prrof packing as an integral product；This structure is because simply very
Easily make, its cameron core body region size changes at random according to riser buss neck size；Phase scheme riser buss neck and casting
Connecting portion devises necking part, i.e. rising head and casting contact site is smaller, only a circular planes, is easily formed less
Thermal center is contacted, generation contracting vacancy at casting thermal center circle is reduced and falls into, and to remove the horizontal section that cast gate has reserved stress concentration.
The present apparatus is adapted to high carbons steel alloy class, such as high carbon abrasion resistant steel, potassium steel class product, it is impossible to using gas flame cuttiug rising head, only
Can in a manner of striking off remove feeders product.
Preferably, described cameron core body is positioned at contact thermal center region.According to product size specifications design cameron core body,
And obtain and most reasonably contact thermal center area.
Preferably, described necking part is circular ring.Obtain the ring shaped contact between heating sleeve and casting body
Face.
Preferably, described heating sleeve epimere is cylinder, hypomere is cone, corresponding with heating sleeve, on rising head
Section is cylindrical hole.Rising head epimere cylindrical hole coordinates hypomere conical bore, forms press-down type trend, meets the unimpeded of potting syrup and pours into
Quality.
Preferably, the base angle of described cameron core body conical bore is 45 ° ± 15 °.Form best horizontal section.
The beneficial effects of the utility model are：Cameron core body is formed integrally with heating sleeve completely, and production and application is convenient, is saved
Operating time；The heating sleeve of integral structure, independent damp-prrof packing, not moisture-sensitive produce gas hole defect；The necking down of circular ring structure
Portion is easy to match with casting face, and casting avoids producing because of degree of agreement difference using single cameron core without additionally polishing
Fleshiness part；Cameron core body part is simple in construction, and opening size can change at random according to heating sleeve neck size, no
Limited by rising head diameter；Cameron core body is high temperature resistant heat preservation material as heating sleeve, generates heat and is incubated after pouring molten steel
Performance is good, will not ahead of time freeze, heating sleeve neck is reduced with casting connecting portion area, rising head is relative with casting contact site
Reduce, so as to obtain less contact thermal center, reduce generation contracting vacancy at casting thermal center circle and fall into；It is not only suitable for high carbons alloy
The casting of steel class, such as high carbon abrasion resistant steel, potassium steel class product, and meet that gas flame cuttiug rising head can not be used, can only be with the side of striking off
The production of formula remove feeders.
