To achieve these goals, the invention provides a kind of metalwork casting method, comprising: prepare molding sand; Preparation prototype and/or core; Use described molding sand, described prototype and/or described core production cope and drag box; By the cope of making and drag box mould assembling; In space by molten metal from cast gate is poured into mould assembling; Cool metal part also takes out from sandbox; And cooled metalwork is carried out to surface treatment.
Preferably, described molding sand is to be mixed by a certain percentage by roughing sand, binding agent and water; The profile of described prototype is consistent with the metalwork of required production with size; Described core is resin sand core, through mold heated extruding coremaking.
Preferably, the described molding sand of described use, the step of described prototype and/or described core production cope and drag box comprises: the molding sand after preparation is poured in described cope and drag box, use the molding sand in described prototype and sandbox to push after formation apperance, take out described prototype and described core is placed on to the precalculated position in the apperance forming on described drag box, again by cope and drag box mould assembling, wherein, the cavity forming after described cope and drag box mould assembling is the outer surface of required production metalwork, the outer surface of described core is the inner surface of required production metalwork.
Preferably, the described step by the cope of making and drag box mould assembling comprises: at least one cast gate is bored on molding sand surface during mould assembling in described cope, described cast gate bottom is communicated with running channel, and the metal after described fusing pours in the cavity forming after mould assembling by described cast gate.
Preferably, described cool metal part comprising from the step that sandbox takes out: the metal sizing and molding sand are together taken out in drag box to be placed on from described and carry out molding sand cooling and that metal surface is adhered in water and clean.
Preferably, describedly cooled metalwork is carried out to surface-treated step comprise: cooled metalwork is taken out and it is carried out to surface treatment.
Preferably, described surface treatment comprises deflashing and polishing.
In method involved in the present invention, prepare molding sand and load sandbox, and use the molding sand in prototype and sandbox to push after formation apperance, take out prototype and also core is placed on to the precalculated position in the apperance forming on drag box, then by cope and drag box mould assembling, like this, the cavity forming after described cope and drag box mould assembling is required production metalwork, then metal liquid is injected from sprue gate, carries out surface treatment after it is cooling, the product size obtaining is stable, smooth surface.
Other features and advantages of the present invention partly in detail are described the specific embodiment subsequently.
Accompanying drawing explanation
Accompanying drawing is to be used to provide a further understanding of the present invention, and forms a part for description, is used from explanation the present invention, but is not construed as limiting the invention with the specific embodiment one below.In the accompanying drawings:
Fig. 1 is the flow chart of metalwork casting method of the present invention;
Fig. 2 is the structural representation of the cope of metalwork casting method of the present invention.
Fig. 3 is the structural representation of the drag box of metalwork casting method of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the present invention, is not limited to the present invention.
The invention provides a kind of metalwork casting method, as shown in Figure 1, comprising: prepare molding sand; Preparation prototype and/or core; Use described molding sand, described prototype and/or described core production cope and drag box; By the cope of making and drag box mould assembling; In space by molten metal from cast gate is poured into mould assembling; Cool metal part also takes out from sandbox; And cooled metalwork is carried out to surface treatment.
In the present embodiment, in order to make product casting rear surface smooth, reduce overlap and modeling process Sand better moulding and laminating prototype and core, described molding sand is to be mixed by a certain percentage by roughing sand, binding agent and water, for example roughing sand is 80% to 90%, binding agent is 5% to 10%, and water is 5% to 10%; Up to standard for the metalwork profile and the size that make to produce, the profile of described prototype is consistent with the metalwork of required production with size; In order to make the core can recycling after production and processing, described core be resin sand core, through mold heated extruding coremaking.Like this, after casting finishes, damaged core can be ground into Powderedly, as the core that reclaims prepared using mold heated Cheng Xin, reuse, save production cost.
In the present embodiment, as shown in Figures 2 and 3, for the profile of required production product and size being shaped in sandbox, molding sand after preparation is poured in described cope and drag box, use the molding sand in described prototype and sandbox to push after formation apperance, for the inner surface configuration of required production product and size being shaped in sandbox, take out described prototype and described core is placed on to the precalculated position in the apperance forming on described drag box, again by cope and drag box mould assembling, wherein, the cavity forming after described cope and drag box mould assembling is the outer surface of required production metalwork, the outer surface of described core is the inner surface of required production metalwork.
In the present embodiment, for convenient artificial or machine casting metal liquid, molding sand surface in described drag box is by artificial grooving or in prototype, design running channel and form the apperance with running channel with molding sand extruding again, at least one cast gate is bored on molding sand surface during mould assembling in described cope, described cast gate bottom communicates with running channel, and the metal after described fusing pours in the cavity forming after mould assembling by described cast gate.Like this, the metal after fusing can form the metalwork that actual needs is produced after flowing into cavity.
In the present embodiment, for cost-saving, prevent the wasting of resources, the metal after sizing and molding sand are together taken out in drag box to be placed on from described and in water, carry out molding sand cooling and that metal surface is adhered to and clean.Like this, by the flowing and wash away of water, the molding sand that is attached to metalwork surface is cleaned, simultaneously due to Action of Gravity Field, molding sand deposits, and after collection, can recycle, reconfigured.So recycle repeatedly, reached good cost-saving effect.
In the present embodiment, because a lot of metalworks are higher to its surface requirements as appearance member, therefore, after cooled metalwork is taken out, need to carry out surface treatment to it, comprise deflashing, polishing.
Below describe by reference to the accompanying drawings the preferred embodiment of the present invention in detail; but; the present invention is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition, each concrete technical characterictic described in the above-mentioned specific embodiment, in reconcilable situation, can combine by any suitable mode, for fear of unnecessary repetition, the present invention is to the explanation no longer separately of various possible combinations.
In addition, between various embodiment of the present invention, also can be combined, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
