Description
Technical field
The utility model relates to a kind of fixed device of stalk, especially a kind of liters for aluminum alloy low-pressure casting process
Liquid pipe fixing device belongs to aluminum alloy casting technique apparatus field.
Background technique
At present in aluminum alloy low-pressure casting process, the general water intake mode that casts is divided into two kinds: one is pass through stalk
Directly cooperate with mold and intakes.Another kind is that molten aluminum transition heat insulation box is connected between stalk and mold, passes through molten aluminum mistake
It crosses incubator and mold cooperation is intake.Regardless of water intake mode, stalk has been required, and has needed the fixed dress of stalk
It sets.The shape of stalk is generally divided into pipe shaft and pipe larynx two parts, pipe shaft be it is straight, pipe larynx is inverted conical shape.Using liter liquid
Pipe larynx temperature is important when pipe, because often aluminum water is easiest to adhesion at the position, which needs higher temperature
Degree guarantees, therefore just needs two aspects to act in the fixed device of stalk in this way.On the one hand, stablize, fixed stalk.Another party
Face keeps the temperature stalk.Most of stalks fixation device designs are whole at present, can only generally be applicable in single part or cast gate
The identical part in position, does not have interchangeability completely.For different products, when gate location is different, need to dismantle again
Device is fixed with corresponding stalk is installed, manpower and labor intensity are also larger.
Summary of the invention
A kind of general interchangeability that the purpose of this utility model is designed aiming at above-mentioned insufficient is strong, can be with quick-replaceable
, the fixed device of the stalk that heat insulation effect is good.
The technical solution of the utility model is: insulation cover being housed, insulation cover includes ring-type at holding furnace upper end opening
Connection ontology, loaded on connection ontology upper end sink hole at shunting lid, shunt lid and connection ontology upper end sink hole between
Gap is 0.8-1mm, shunts cover outer wall and is equipped with the stage portion assembled with sink hole cooperation, shunting lid middle part is equipped with more than one and fills
Distribution, through flange loaded on shunting at the pilot hole covered, stalk pipe shaft is located in insulation cover and heat preservation furnace chamber stalk pipe larynx.
The cricoid connection ontology lower end is connect through bolt with holding furnace.
Cricoid connection ontology lower end flange with outward extension, flange are equipped with installation corresponding with bolt
Hole.
The cricoid connection inner body wall is equipped with multiple reinforcing ribs, and the reinforcing rib is at sink hole.
The reinforcing rib is uniformly disposed circumferentially connection inner body wall.
The pilot hole includes superposed cylindrical bore, the cylindrical hole positioned at lower part.
The shunting lid is loaded at connection ontology upper end sink hole through asbestos pad.
The sink hole is kidney-shaped sink hole.
The seam allowance width L of the sink hole is greater than 15mm.
The utility model is adopted a split structure to be covered by connection ontology and shunting and be formed, and connecting ontology and shunting to cover to cooperate makes
With being the versatility and interchangeability for improving product, cancel replacement ontology, reduces replacement intensity.The device is set for different ingates
That sets needs only to need replacing shunting lid, does not need replacement connection ontology.
The fixed device of the stalk mainly has the advantage that one, is designed to connection ontology and shunting that two cooperations are placed
Lid, instead of whole integral manner.Two, it replaces different cast gate products and only needs replacing shunting lid, shunting lid is the direct company of putting into
It connects in ontology, replacement efficiency is fast, and connector is then permanently affixed on holding furnace, basic not have to dismounting.Three, shunting, which is covered, to be replaced
Before, it can be heated in advance with gas, lean on furnace gas to its heating time after reducing replacement, shorten the production cycle.Four, present apparatus design is filled
The uplifting pressure that holding furnace point is utilized makes to fill a device is in impaction state at work, uses asbestos pad pressure between each component
, guarantee not generate gas leak phenomenon when work.Shunting the gap between lid and connection ontology upper end sink hole is 0.8-1mm, should
The setting one side of gap parameter is based on facilitating shunting lid and connect ontology assembly, on the other hand takes into account and shunting is facilitated to cover and connect
The setting of ontology leakage problem, the gap parameter reduces gas leakage, reinforces heat insulation effect.Connect stopping for the sink hole of 2 upper end of ontology
Mouth One-sided Widths L is greater than 15mm, and the setting of the width parameter guarantees sealed width, prevents gas leakage, reinforces heat insulation effect.
Detailed description of the invention

Fig. 3 is the structural schematic diagram of cover board.
In figure, 1, holding furnace, 2, connection ontology, 3, shunting lid, 4, stalk, 5, die ontology, 6, asbestos pad, 7, spiral shell
Bolt, 8, molten aluminum, 9, through-hole, 10, kidney-shaped sink hole, 11, reinforcing rib, 12, cylindrical bore, 13, cylindrical hole.
Specific embodiment
In Fig. 1,2,3, the utility model includes the connection ontology 2 connecting with holding furnace 1, shunts lid 3, asbestos pad 6, bolt
7 etc..Connecting ontology 2 is the profile-followed peviform structure of kidney-shaped, it include kidney-shaped sink hole, connect with holding furnace 1 cooperate have upper spiral shell
The kidney-shaped flange of bolt throughhole.Connection 2 upper and lower end parts of ontology are all unlimited, and inside is provided with the reinforcing rib 11 being evenly distributed, and are mentioned
Height connection 2 rigidity of ontology and intensity.Its material is cast iron materials, is deformed small.The seam allowance One-sided Widths L of kidney-shaped sink hole is greater than
15mm is arranged the width and guarantees sealed width, prevents gas leakage.2 inside of connection ontology is vacant to be connected as one with holding furnace 1, base
It originally can achieve consistent with the furnace gas temperature of holding furnace 1, heat insulation effect is good.
Shunt 3 material of lid with connection 2 material of ontology it is consistent, reduce modified difference, shunt 3 shape of lid be in kidney-shaped shape, with connect
The kidney-shaped sink hole for connecing ontology 2 matches, gap 0.8-1mm.The intermediate position of lid 3 is shunted to be provided with and the cooperation of stalk 4
Cylindrical bore 12 and cylindrical hole 13, cylindrical bore 12 will be lower than stalk flange thickness.Cylindrical hole 13 it is straight
Diameter is slightly larger than 4 caliber of stalk.The position of cylindrical bore 12 and cylindrical hole 13 is the formulation according to needed for the cast gate of product
, the position is different, and shunting lid 3 is just different, carries out replacing different shunting lids 3 using required according to different cast gates.
When installation, asbestos pad 6 is first placed in plane on holding furnace 1, ontology 2 and heat preservation will be connected by passing through through-hole 9 for bolt 7
Furnace 1 is fixed.After being put into asbestos pad 6 in the kidney-shaped sink hole 10 of connection ontology 2, lid 3 will be shunted, groove profile of galloping along on horseback is pressed into shape
In sink hole 10.After being finally put into asbestos pad 6 in cylindrical bore 12, stalk 4 is put into the cylindrical bore for shunting lid 3
In 12.
In production process, after asbestos pad 6 is put on the flange face of stalk 4, as holding furnace 1 slowly rises, stalk 4
Flange face it is also slowly close towards mold, until dieback rise it is motionless.At this moment, entirely fixed device is all that impaction state is presented
's.When work, molten aluminum 8 rises as the furnace gas air pressure in holding furnace 1 increases along the inner cavity of stalk 4, finally enters mould
Have in ontology 5.
After production, holding furnace 1 is slowly landed, the flange face of stalk 4 slowly after break away from moulds ontology 5, first will
Stalk 4 takes out, and then, the original lid 3 that shunts is further taken out, the new shunting lid 3 of product to be produced is replaced, then suitable according to installing
Sequence is reinstalled.
