Description
Technical field
The utility model belongs to foundry goods field of tool, specifically refers to a kind of cubic gate stick being applied to gear arm castings production.
Background technology
Model casting is also known as " lost-wax casting ".Model casting typically refers to makes apperance at fusible material, makes shell at apperance Surface coating some layers of refractory material, then shell is discharged in apperance fusing, thus obtains the casting mold without die joint, gets final product the founding method of back-up sand cast after high-temperature roasting.Because apperance extensively adopts wax material to manufacture, therefore often model casting is called " lost-wax casting ".
Current gear arm foundry goods mainly adopts solvent casting method to cast.Solvent casting mainly comprises three processes: one for manufacturing casting wax mould; Two is hanging sand crust; Three is shaping for building.Need to use gate stick in hanging sand crust process, existing gate stick comprises cup, sprue and ingate, and ingate main body is casting wax mould, and ingate is connected with the side of sprue.In hanging sand crust process, due to Action of Gravity Field, casting wax mould and ingate usually can come off, and will pound the casting wax mould of below after the casting wax mould above being positioned at comes off, and the casting wax mould of below is also come off from sprue.Due to the frequent generation of this kind of phenomenon, therefore the yield rate of foundry goods is always not high.
In addition, existing gate stick sprue mostly be square, when ingate and casting wax mould profile larger time, for gear arm, sprue needs to use more paraffin.
Utility model content
The purpose of this utility model is: overcome the above-mentioned defect of prior art, a kind of cubic gate stick being applied to gear arm castings production is provided, come off to reduce casting wax mould and affect normally building of foundry goods in hanging sand crust, and then the casting yield of lifting solvent casting.
The utility model is achieved through the following technical solutions:
A kind of cubic gate stick being applied to gear arm castings production, comprise cup and be positioned at the sprue below cup, described cup is vertically connected on the end face of sprue, the cross section of described sprue is rectangle, the side of described sprue is connected with multiple ingate from top to down, the ingate being positioned at top is provided with the first reinforcement lacing wire, and described first one end strengthening lacing wire is connected with ingate, and the other end is connected with cup.
By setting up the first reinforcement lacing wire, effectively can reduce casting wax mould and ingate and coming off at hanging sand crust, avoiding affect normally building of foundry goods, and then the casting yield of lifting solvent casting.
In addition, existing gate stick sprue mostly be square, when ingate and casting wax mould profile larger time, for gear arm, sprue needs to use more paraffin.By the cross section of sprue is set to rectangle, the side at rectangle longer sides place is connected with ingate, effectively can reduce the consumption of sprue for wax stock, reduce costs.
As the preferred mode of one, each side of described sprue is provided with multiple ingate symmetrically.By each side at sprue, ingate is set symmetrically, the centre-of gravity shift of gate stick can be avoided, ensure gate stick not run-off the straight.
As the preferred mode of one, also comprise the second reinforcement lacing wire, described second one end strengthening lacing wire is connected with sprue, and the other end is connected with ingate.By setting up the second reinforcement lacing wire, effectively can promote the impact resistance of each ingate, minimizing casting wax mould comes off at hanging sand crust and affects normally building of foundry goods further, promotes the casting yield of solvent casting.
As the preferred mode of one, also comprise axle, described axle, through the center of sprue, the barred body of described axle has the depression on two different directions at least.Existing axle mostly is uniform cylinder, by having the depression on two different directions on the barred body of axle at least, can effectively avoid sprue to come off from axle, ensures normally carrying out of follow-up work, promotes the casting yield of solvent casting.
As the preferred mode of one, described axle upper side is arranged with handle.
As the preferred mode of one, described axle is hollow steel pipe, and the inside of described hollow steel pipe is filled with filler.Axle adopts hollow steel pipe to make, and not only draws materials conveniently, and saves steel.Axle is by filling filler, and preferred cement is filled, and paraffin can be avoided to enter hollow steel pipe, thus avoid the waste of paraffin.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the utility model is by setting up the first reinforcement lacing wire, effectively can reduce casting wax mould and ingate and come off at hanging sand crust, avoid affect normally building of foundry goods, and then the casting yield of lifting solvent casting;
(2) the utility model is by being set to rectangle by the cross section of sprue, and the side at rectangle longer sides place is connected with ingate, effectively can reduce the consumption of sprue for wax stock, reduce costs;
(3) the utility model is by arranging ingate symmetrically in each side of sprue, can avoid the centre-of gravity shift of gate stick, ensures gate stick not run-off the straight;
(4) the utility model by having the depression on two different directions at least on the barred body of axle, can effectively avoid sprue to come off from axle, ensures normally carrying out of follow-up work, promotes the casting yield of solvent casting;
(5) the utility model axle adopts hollow steel pipe to make, and not only draws materials conveniently, and saves steel, and axle is by filling filler, and preferred cement is filled, and paraffin can be avoided to enter hollow steel pipe, thus avoid the waste of paraffin.
