Abstract
An object of the utility model is to provide an exothermic heat -preservation feeder of area buffering psammitolite cover, including the riser bush body, the inside buffering psammitolite that has cup jointed of lower extreme of riser bush body, the buffering psammitolite is equipped with the through -hole along the axial. The utility model discloses a setting of buffering psammitolite can slow down the high -pressure pressure when modelling, prevents that riser bush from can be prolonged the setting time of the interior metal liquid of riser bush by fracturing, the while, improves feeding efficiency and process yield.
Description
Technical field
The utility model belongs to the technical field of sand casting, and more particularly to a kind of heat preservation with buffering core emits
Muzzle.
Background technology
Casting is to be poured into liquid metal to have in the casting mold die cavity being adapted with part shape, size, treats its cooling
Solidification, to obtain the production method of blank or part.In casting process, after pouring metal melt enters casting mold, due to cooled and solidified,
Solid-state is switched to by liquid, produces volume contraction.When volume contraction cannot get molten metal supplement, after solidification, modulus in foundry goods
Larger position can produce shrinkage cavity and shrinkage porosite.For the casting alloy that those volume contractions are larger, this defect often occurs.Contracting
Hole, shrinkage porosite can make mechanical property, air-tightness and the materialization of foundry goods substantially reduce, and reduce the net sectional area of foundry goods, or even become
For waste product.Therefore must try to control solidification, prevent defect from producing.Riser buss is set at the position of foundry goods final set, contracting
Hole is introduced in riser buss, finally prescinds riser buss, is to control solidification at present in casting industry, compensate the most effective, of contraction
The technological measure of popularization.
Common sand mold riser buss is stronger due to heat-sinking capability, and the heat transfer of riser buss metal and thermal radiation loss are big, solidification
Speed is fast, and its feeding efficiency is only 10%～14%, and most riser buss metals are actually a kind of reactive power consumption.More
Importantly, existing riser buss be used for high-pressure molding line when, often because bear the pressure of incessantly high pressure moulding and by pressure break it is impossible to
Meet the requirement of high-pressure molding line.
Utility model content
The purpose of this utility model is to provide a kind of heat preservation riser buss with buffering core, by buffering core
Setting, can slow down high-pressure during moulding, prevent riser buss by pressure break, can extend the solidifying of riser buss inner metal liquid simultaneously
Gu the time, improving feeding efficiency and product yield.
The utility model adopts the following technical scheme that：
A kind of heat preservation riser buss with buffering core, including riser buss body, in the lower end of described riser buss body
Portion is socketed with buffering core, and described buffering core is provided with through hole vertically.
Above-mentioned band buffers the heat preservation riser buss of core, described riser buss body be axially inside provided with ladder
Hole, the diameter on described shoulder hole top is less than the diameter of shoulder hole bottom.
Above-mentioned band buffers the heat preservation riser buss of core, the top of described buffering core cylindrical and with described
The inwall of shoulder hole bottom is in close contact.
Above-mentioned band buffers the heat preservation riser buss of core, and the top of described buffering core is uniform along outer circumference surface direction
Some positive stop strips and described positive stop strip is abutted against with the bottom face phase of riser buss body.
Above-mentioned band buffers the heat preservation riser buss of core, and the top of described riser buss body is provided with venthole.
Above-mentioned band buffers the heat preservation riser buss of core, and the top of described shoulder hole is equipped with bellmouth, described cone
The top in shape hole extends to venthole.
Above-mentioned band buffers the heat preservation riser buss of core, and the bottom of described riser buss body is in rounding mesa-shaped.
The utility model be particularly well-suited on high-pressure molding line using it is ensured that riser buss in moulding by high-pressure situations
Under will not be damaged, specifically have the beneficial effect that：
（1）In casting technique, when riser buss is used on high-pressure molding line, need first riser buss to be placed on mould,
Then again sand is filled into sandbox and consolidation carried out to sand using very high pressure, now riser buss all can be by high pressure pressure
Broken, therefore cannot meet the Production requirement of high-pressure molding line.For the problem of above-mentioned high-pressure molding line, the utility model is little
On the premise of amount increases cost, by setting buffering core, when riser buss body bears the high pressure of moulding, buffering core overcomes
Positive stop strip, positive stop strip crushes, and buffering core starts slowly to move up, and after the completion of moulding, buffering core is pressed into riser buss originally
Internal portion, the bottom face of buffering core bottom face and riser buss body maintains an equal level, thus offsetting moulding pressure, effectively prevent and emit
Muzzle body, by pressure break, solves the problems, such as that riser buss body cannot be applied to high pressure moulding production line because of intensity deficiency.
（2）Riser buss set described in the utility model is made after being mixed with exothermic material by insulation material, riser buss
Exothermic material in set reacts releasing heat at high temperature, and insulation material plays heat insulation effect simultaneously, decreases the heat of molten metal
Amount is scattered and disappeared, and the molten metal internal to riser buss set is incubated, and the setting time of prolongation molten metal is it is ensured that metal in riser buss
The solidification of liquid is later than casting solidification, realizes the long-time feeding to foundry goods it is ensured that obtaining the foundry goods of dense structure, simultaneously also not
The metal liquid measure that feeding effect directly occurs is reduced to relatively low limit, thus improving feeding efficiency and product yield.
(3) bottom of the utility model riser buss body is rounding mesa-shaped, and upper end diameter is more than lower end diameter, so emitting
The bottom of muzzle body is little with the contact area of foundry goods, and when clearing up foundry goods, riser buss is easy to remove, and reduces cutting rising head
The amount of labour of set.
