Abstract
The utility model proposes a kind of wax-pattern has automatic exhaust device, including upper die and lower die, packing cavity between the upper die and lower die, is provided with, described filler chamber side is provided with charging aperture；Described filler chamber top is connected with exhaust apparatus, the exhaust apparatus includes the exhaust duct connected with the charging aperture top, the exhaust duct end is taper, and the aerofluxuss cone for exhaust duct is sealed is provided with the exhaust duct, and the aerofluxuss cone end is provided with spring；The exhaust duct side is communicated with air discharge duct, this device increased a special aerofluxuss cone at the original position for needing aerofluxuss, this facies cerebellaris pyramidis has spring to connect, before mold cavity fills type, opening is presented open mode, this is that mold cavity has good exhaust effect, when wax material is soon full of die cavity, using the pressure of wax material itself, aerofluxuss cone is withstood, so as to close exhaust apparatus, overlap is prevented, the elastic force of spring can be adjusted in use, ensure that suitable cone closes opportunity.
Description
Technical field
This utility model is related to hot investment casting field, more particularly to a kind of wax-pattern tool automatic exhaust device.
Background technology
In hot investment casting industry, wax-pattern by Making mold out, but during wax fills type, wax is by high speed and high pressure
Nozzle injection mould in, wax material high-speed filling mold cavity, but the air inside mould usually comes because mould is airtight
Not as good as excluding outside mold cavity, this just makes resistance to filling type, thus the not enough problem of type of filling occurs, traditional solution is
Increase some exhaust needles and air discharge duct and venting plug, exhaust needle because fit clearance will be amplified, could aerofluxuss, but solving
The overlap of wax-pattern product is increased while problem, air discharge duct can increase the workload of the removal air discharge duct of follow-up wax-pattern product,
And venting plug Jing is often easily demolded agent and wax material blocking, it is impossible to play a role well.
Utility model content
For solve above-mentioned technical problem, the utility model proposes a kind of wax-pattern tool automatic exhaust device, including upper mould and
Lower mould, is provided with packing cavity between the upper die and lower die, described filler chamber side is provided with charging aperture；Described filler chamber top connects
There is exhaust apparatus, the exhaust apparatus includes the exhaust duct connected with the charging aperture top, and the exhaust duct end is taper,
The aerofluxuss cone for exhaust duct is sealed is provided with the exhaust duct, the aerofluxuss cone end is provided with spring；The aerofluxuss
Road side is communicated with air discharge duct.
Preferably, the aerofluxuss cone includes the body of rod, and described body of rod one end is provided with fixture block, and the other end is provided with circular cone, institute
State the body of rod end of the exhaust duct can be sticked in activity in the exhaust duct, the circular cone.
Preferably, the spring top is provided with adjusting nut, and the adjusting nut is engaged on the upper mould.
The utility model proposes wax-pattern tool automatic exhaust device have following beneficial effect：This device needs row in original
The position of gas increased a special aerofluxuss cone, and this facies cerebellaris pyramidis has spring to connect, and spring can adjust elastic force, in mould
Before tool die cavity fills type, opening is presented open mode, and this is that mold cavity has good exhaust effect, when wax material is soon full of type
When chamber, using the pressure of wax material itself, aerofluxuss cone is withstood, so as to close exhaust apparatus, prevent overlap, used
In can adjust the elastic force of spring, ensure that suitable cone closes opportunity.
Description of the drawings
For the technical scheme being illustrated more clearly that in this utility model embodiment, below will be to needed for embodiment description
Accompanying drawing to be used is briefly described.
Fig. 1 is structural representation of the present utility model；
Wherein, the upper moulds of 1-, mould under 2-, 3- packing cavities, 4- charging apertures, 5- exhaust ducts, 6- aerofluxuss cones, 7- springs, 8- rows
Air drain, 9- adjusting nuts.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe.
As shown in figure 1, the utility model proposes a kind of wax-pattern has automatic exhaust device, including upper mould 1 and lower mould 2, institute
State and between mould 1 and lower mould 2, be provided with packing cavity 3,3 side of described filler chamber is provided with charging aperture 4；3 top of described filler chamber connects
There is exhaust apparatus, the exhaust apparatus includes the exhaust duct 5 connected with 4 top of the charging aperture, and 5 end of the exhaust duct is cone
Shape, is provided with the aerofluxuss cone 6 for exhaust duct 5 is sealed in the exhaust duct 5,6 end of aerofluxuss cone is provided with spring 7；
5 side of the exhaust duct is communicated with air discharge duct 8,
Working method of the present utility model is：When wax liquor is entered in packing cavity 3 from inlet, aerofluxuss cone 6 is in aerofluxuss
It is open mode between road 5, as wax liquor gradually increases so that the air in packing cavity 3 gradually enters air discharge duct from exhaust duct 5
8 and gas is discharged, when wax liquor is gradually filled, aerofluxuss cone 6 can be promoted gradually to seal discharging opening, effectively prevent wax material from producing
Raw overlap, the step of reduce deflashing, greatly improves work efficiency.
Preferably, the aerofluxuss cone 6 includes the body of rod, and described body of rod one end is provided with fixture block, and the other end is provided with circular cone, institute
State the body of rod end of the exhaust duct 5 can be sticked in activity in the exhaust duct 5, the circular cone.
In order to adjust the elastic force of spring 7,7 top of the spring is provided with adjusting nut 9, and the adjusting nut 9 is engaged in institute
State on mould 1, rotate adjusting nut 9 and press spring 7, adjust the elastic force of spring 7, ensure that suitable cone closes opportunity.
Various modifications to embodiment will be apparent for those skilled in the art, determined herein
The General Principle of justice can be realized in the case of without departing from spirit or scope of the present utility model in other embodiments.Cause
This, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
