Description

A kind of column, lathe bed integral-casting method

Technical field

The present invention relates to two or more foundry goods integral-casting methods, especially relate to a kind of column, lathe bed integral-casting method.

Background technology

Inblock cast is bolted.Monomer casting structure is relatively simple, manufacturing technology is very ripe, as guide pass is placed on below pouring position by lathe bed casting technique usually, adopt closed bottom surface influent stream running gate system, guide pass is placed on below pouring position by column casting technique usually, adopt positive-pressure gating system, along column guide rail termination influent stream.Lathe bed, Pillar Castings inblock cast, its casting quality is highly stable, and qualification rate is all more than 98%, due to lathe bed and column be carry out separately accurately machined, therefore, in groups of machine process of assembling, there will be lathe bed and column fit clearance and the problem such as not mate, cause foundry goods to be scrapped.

Up to the present, a kind of method overcoming above-mentioned defect is not also had.

Summary of the invention

The object of the invention is the defect overcoming prior art, provide a kind of method unique, reduce placer iron ratio, cost-saving, a kind of column, the lathe bed integral-casting method of enhancing productivity.

The present invention realizes in the following way:

A kind of column, lathe bed integral-casting method, comprise design, coremaking, moulding, mould assembling, cast and shake out cleaning, it is characterized in that: such scheme is that below bed ways are placed on, column guide rail is placed on side, column and lathe bed are in same case and taken out of by crust;

Apperance in described moulding is divided into apperance, lower apperance, rear apperance, by above-mentioned three apperances respectively rivet on three flat boards, form cope match-plate pattern, lower bolster and rear pattern plate respectively, make 2 flat boards again, be defined as front template and side template respectively, at lower bolster and front template at corresponding position Design Orientation pin, at the corresponding position Design Orientation pin of rear pattern plate and side template; Sandbox in described moulding is that three pairs are respectively: 1# sandbox, 2# sandbox and 3# sandbox, and 2# sandbox has two open ports, and they are adjoining vertical surface;

Describedly be shaped to following steps:

A, on moulding platform, first place described cope match-plate pattern, then place described 1# sandbox, back-up sand, consolidation, molding after sclerosis;

B, on moulding platform first horizontal positioned lower bolster, then place front template perpendicular to lower bolster, check that two templates are whether vertical with 1m square, guarantee vertical after in alignment pin place bolted two templates of correspondence;

C, place described 2# sandbox, sandbox nowel mouth is placed horizontally on described lower bolster, the side mouth of sandbox and the spacing of front template must not be greater than 3mm, back-up sand, consolidation, after sclerosis during molding, first remove the connecting pin between lower bolster and front template, then 2# sandbox and front template are sling simultaneously and turned over turnback;

D, on moulding platform rear pattern plate described in first horizontal positioned, again perpendicular to rear pattern plate setting side template, check that whether two templates are vertical with 1m square, guarantee alignment pin place bolted two templates in correspondence vertically, place 3# sandbox, back-up sand, consolidation, molding after sclerosis, tears rear pattern plate, side template open;

Described mould assembling is following steps:

A, core assembly: the core placing counter structure in described 2# sandbox;

B, described 3# sandbox and 2# sandbox to be combined in the horizontal direction, and clamped with clamp;

C, described 1# sandbox vertically to be combined with 2#, 3# sandbox, and clamped with clamp.

The present invention has following effect:

1) method is unique: method provided by the invention comprises design, coremaking, moulding, mould assembling, cast and shake out cleaning, it is characterized in that: such scheme is below bed ways are placed on, column guide rail is placed on side, and column and lathe bed are in same case and taken out of by crust; This invention can be applicable on other products, as lathe bed and Electric Appliance Cabinet base integral-casting, and the Foundry Production of the combination cast of the similar structures such as gantry upright post and back timber integral-casting.

2) method provided by the invention two foundry goods integral-castings, when the later stage carries out fine finishining, fine finishining is same benchmark, can not there is the bad problem of assembling when assembling unit.

3) method provided by the invention reduces placer iron ratio, cost-saving.

4) method provided by the invention two foundry goods are cast simultaneously and are enhanced productivity.

Detailed description of the invention

A kind of column, lathe bed integral-casting method, the method comprises design, coremaking, moulding, mould assembling, cast and shake out cleaning, as Fig. 1,2, shown in 3 and 4: such scheme is that below bed ways are placed on, column guide rail is placed on side, and column and lathe bed are in same case and taken out of by crust.

Apperance in described moulding is divided into apperance, lower apperance, rear apperance, by above-mentioned three apperances respectively rivet on three flat boards, form cope match-plate pattern 1, lower bolster 2 and rear pattern plate 4 respectively, make 2 flat boards again, be defined as front template 3 and side template 5 respectively, at lower bolster 2 and front template 3 at corresponding position Design Orientation pin, at the corresponding position Design Orientation pin of rear pattern plate 4 and side template 5; Sandbox in described moulding is that three pairs are respectively: 1# sandbox, 2# sandbox and 3# sandbox, and 2# sandbox has two open ports, and they are adjoining vertical surface.

Describedly be shaped to following steps:

A, on moulding platform, first place described cope match-plate pattern 1, then place described 1# sandbox, back-up sand, consolidation, molding after sclerosis;

B, on moulding platform first horizontal positioned lower bolster 2, then place front template 3 perpendicular to lower bolster 2, check that whether two templates vertical with 1m square, guarantee vertical after in alignment pin place bolted two templates of correspondence;

C, place described 2# sandbox, sandbox nowel mouth is placed horizontally on described lower bolster 2, and the side mouth of sandbox and the spacing of 3# template must not be greater than 3mm.Back-up sand, consolidation, after sclerosis during molding, first remove the connecting pin between lower bolster 2 and front template 3, then 2# sandbox and front template 3 sling simultaneously and turn over turnback;

D, on moulding platform rear pattern plate 4 described in first horizontal positioned, again perpendicular to rear pattern plate 4 setting side template 5, check that whether two templates are vertical with 1m square, guarantee alignment pin place bolted two templates in correspondence vertically, place 3# sandbox, back-up sand, consolidation, molding after sclerosis, tears rear pattern plate 4, side template 5 open.
