Abstract
The utility model relates to a split die cavity for flow distribution plate castings of a blast furnace hot blast stove, which is characterized in that a die cavity core and a split male die cavity are combined in the vertical direction to form a die cavity of a flow distribution plate monomer casting, and the die cavity cores of each flow distribution plate monomer casting are connected in series in the vertical direction to form a plurality of layers of die cavities combined by a plurality of monomer casting die cavity cores; the die cavity core and the male dies are in a parting surface structure; and the die cavity core box is in a parting box surface structure. The die cavity is applicable to casting the castings with complex shapes, effectively solves the problems of the parting and die sinking of the complex die cavity, meets the requirement of the casting precision, reduces the cost for making the die cavity, reduces the production period and improves the production efficiency.
Description
Technical field
The utility model relates to a kind of casting mold cavity.
Background technology
At present, domestic large quantities of newly-built, the reconstruction blast furnace adopts is the design of KALUGIN top combustion stove, in the fire grate system of its design, porous foundry goods one flow distribution plate that has adopted a kind of having of " four-way " passage is as transition, shunting layer, circle ventilation checkerwork cell that an aperture in the fire grate is bigger and corresponding, the perforation of the circular ventilation checkerwork cell in three small-bores in its top checker brick heat storage are realized the shunting action to hot blast.For ease of making, install, usually according to the pairing checker brick heat storage of flow distribution plate small bore end air grating hole number, flow distribution plate is designed to the structure in 19 holes and 37 holes in the design, a cover hot-blast stove fire grate system need adopt thousands of flow distribution plates.For the ventilation checkerwork cell of guaranteeing thousands of fire grates, flow distribution plate and checker brick is unimpeded, require the casting accuracy of flow distribution plate to reach the CT7 level, any two hole deviation of centre distance are ± 1mm that the pore radius tolerance is ± 0.5mm that the appearance and size tolerance is ± 1mm on the flow distribution plate.For satisfying required precision, usually should adopt hot investment casting mode Foundry Production flow distribution plates such as permanent mold casting, model casting, lost foam casting, but because its air grating hole number is many, the pass structure complexity, the required die cavity manufacturing expense of its Foundry Production is higher, fabrication cycle is also longer, and the limitation of production is bigger; And common sand casting can't be satisfied the casting accuracy requirement, even reduce required precision, adopts the sand casting mode to produce the flow distribution plate foundry goods, and the sand removal after the casting, polishing workload are bigger, are difficult to guarantee requirements of mass production.
The utility model content
The purpose of this utility model provides a kind of blast funnace hot blast stove flow distribution plate casting mold cavity, this die cavity is particularly suitable for casting the foundry goods of complicated shape, efficiently solve complex-shaped surface mould somatotype, open the problem of mould difficulty, satisfy the casting accuracy requirement of product, reduce the die cavity manufacturing cost, shorten the production cycle, improved production efficiency.
The utility model is achieved through the following technical solutions:
A kind of blast funnace hot blast stove flow distribution plate casting mold cavity, this die cavity are constituted the die cavity core of monomer flow distribution plate foundry goods in vertical direction by die cavity core, label split die cavity.
The die cavity core of each monomer flow distribution plate foundry goods is connected in series in vertical direction, forms the multilayer cavity version of a plurality of monomer foundry goods die cavity core combinations.
Parting Surface Design between described die cavity core and the label.
Described die cavity core divides the design of box face.
The mode of the interior alignment pin that the employing core carries between each layer chamber core of described multilayer die cavity, the label is located.
Compared with prior art, the utility model has the advantages that:
1) adopts this die cavity Foundry Production flow distribution plate foundry goods, improved the processing and fabricating precision of frock, can satisfy the casting accuracy requirement of product, reduce the die cavity manufacturing cost, shorten the production cycle, enhance productivity.
2) foundry goods of being produced is through simple polishing, and a spot of processing can have been satisfied the specification requirement of product preferably;
3) adopt the high accuracy of Digit Control Machine Tool processing, complicated metal mold cavity, the precoated sand core shooting, pattern grouping, cored-up mould technology can not rely on the artisan people and enhance productivity, and guarantee product quality.
Description of drawings
Fig. 1 is a flow distribution plate foundry goods core assembly mould assembling schematic diagram.
Among the figure: label 2-foundry goods 3-chamber, 1-upper strata core 4-lower floor label
The specific embodiment
See Fig. 1, a kind of blast funnace hot blast stove flow distribution plate casting mold cavity, this die cavity are constituted the die cavity core of monomer flow distribution plate foundry goods in vertical direction by chamber core, label split die cavity.The die cavity core of each monomer flow distribution plate foundry goods is connected in series in vertical direction, forms the multilayer cavity version of a plurality of monomer foundry goods die cavity core combinations.Dip-coating has the alcohol radical graphite paint on described chamber core, the label.The mode of the interior alignment pin that the employing core carries between each layer chamber core of described multilayer die cavity, the label is located.
The above-mentioned die cavity casting of a kind of use flow distribution plate technology, this process using cored-up mould, pattern grouping, precoated sand core shooting, casting on flat technology, core all adopts the technology mode of dip-coating alcohol radical graphite paint, to guarantee core surface quality and precision.By the design that foundry goods die joint, the core box of uniqueness divides the box face, the somatotype of complex-shaped surface mould core, the problem of Qi Mo have been solved.
The mode of the interior alignment pin that the employing core carries between each layer chamber core of multilayer die cavity, the label is located, and to guarantee the precision of core assembly, mould assembling, reduces artificial factor.
Adopt the high accuracy of Digit Control Machine Tool processing, complicated metal mold cavity to guarantee the die cavity precision; For reducing the shadow of human factor Ring, the chamber core, the label that form die cavity all adopt the precoated sand core shooting, utilize the characteristics that precoated sand can fine reproduction die cavity precision, Guarantee core precision and casting accuracy by the high accuracy die cavity.
