Abstract
The present invention relates to a casting process for large-size statue with a metal shell, which adopts a blocking split loose sand mold process of a sand casting method to lay a layer of filling materials with the same thickness as a casting on the surface of an inner cavity of an outline sand mold which is reproduced, then a core is directly made in the inner cavity, and the mold is closed and poured when the filling materials are removed after the core is made. The present invention has the advantages of simple molding method, no need of manufacturing a core box, low production cost, one-step integral casting molding process of the statue, strong integrity of finished products, good surface quality and vivid appearance image.
Description
The invention belongs to casting technology field, particularly the handicraft global formation casting technique of large-scale metal shell.
Mostly traditional statue making process product casting technique is to adopt Special Processes of Metal Castings methods such as model casting or ceramic mold casting, higher with the handicraft dimensional accuracy that these methods are produced, surface smoothness is good, yet its foundry technology process is complicated, and it is wayward, the material that uses and consume is more expensive, only be applicable to that production is complex-shaped, required precision height or the small-sized part in addition that is difficult to carry out other processing, produce large-scale in addition part or large-scale handicraft housing extremely bothers and difficulty, the producer that has adopts behind the split casting again to large-scale metal statue that welding is assembled into integral body, and not only technology is numerous and diverse, the cost height.And weld seam can have a strong impact on the presentation quality of handicraft, can produce certain deformation during splicing, makes the handicraft associative perception not strong, and surface smoothness is low, also needs extra a large amount of surface finish work that increases.
Purpose of the present invention provides a kind of sand casting method simple with formative method, that cost is low to produce large-scale handicraft housing just and can guarantee the global formation casting technique of handicraft presentation quality for fear of the weak point of said method.
The objective of the invention is to be achieved through the following technical solutions.
The present invention adopts traditional blocked breaking moved sand process, earlier the formpiston with statue turns over its profile sand mo(u)ld of system, behind the taking-up formpiston, is turning over the even place mat one deck of profile sand mo(u)ld internal chamber wall that makes and the charges of statue housing wall thickness uniform thickness, successively the assembly unit of profile sand mo(u)ld is joined then case and simultaneously peace go into the loam core skeleton, the system of pounding inner chamber loam core, the system of pounding is finished to the loam core, and mould assembling finishes, take the somatotype sand mo(u)ld again apart, remove charges, assembly unit somatotype sand mo(u)ld again again, mould assembling cast.
In making statue housing process, done the technology breach with supporting inner chamber loam core core print at housing bottom, after housing was cast, other cast a coverboard amalgamation that matches with breach.
Because the present invention adopts is blocked breaking moved sand process in the sand casting, and used Modeling Material price is low, thereby production cost supports, and technology is simple, and can cast out the large-scale technology statue of any complex appearance.
Since the present invention be at the even place mat of whole profile sand mo(u)ld internal chamber wall directly pound behind the filler of one deck and handicraft housing wall thickness uniform thickness and make the loam core at inner chamber, needn't special again core box coremaking, simplify technology, reduced cost, and can obtain the uniform handicraft housing of wall thickness.
Because the present invention carries out monoblock cast to the handicraft housing to be shaped, the handicraft associative perception that casts out is strong, and surface quality is better, only need do a spot of removing surface polishing work.
The invention will be further elaborated (is example with the cast copper ox) below in conjunction with drawings and Examples:
Fig. 1 is that casting technique master of the present invention looks cutaway view;
The statue with metal shell stereogram of Fig. 2 unabridged version invention;
Use handicraft itself earlier or use metal, gypsum, materials such as fiberglass are made the technology formpiston, turn over the blocked breaking moved sand process and to make handicraft profile sand mo(u)ld 1 (quantity of the sand lump of living is determined according to handicraft complex contour degree), make running gate system 2 simultaneously, then the profile sand mo(u)ld is split, take out formpiston, oven dry profile sand mo(u)ld, evenly spread one deck somatotype material at profile sand mo(u)ld surface of internal cavity, to use foamed plastics, plasticine, the filler 3 that the materials such as clay that fire clay or plasticity are good are made is got the wall thickness of required handicraft discard equably turning over the profile sand mo(u)ld surface of internal cavity that makes, again the sand mo(u)ld of assembly unit profile successively then, assembly unit limit, limit put into loam core skeleton 4 and add core sand pound the system loam core 5, after the loam core system of pounding is finished, continue the intact external form sand mo(u)ld of assembly unit.Take the somatotype sand mo(u)ld again again apart, remove filler, the sand mold loose piece surface of internal cavity and the loam core of taking apart are repaired, paint, oven dry, the last stud of suitably laying is joined case with the assembly unit successively of profile sand mo(u)ld, with smelting good copper alloy liquid cast, the cleaning of unpacking after the cooled and solidified.
Owing to when turning over the handicraft housing,, thereby when casting technique product housing, also will cast a coverboard 7 that matches with the notch geometry size in addition for supporting inner chamber loam core core print stays a technology breach 6, with its amalgamation soldering in the technology indentation, there.
Because being mainly used in, the present invention makes large-scale handicraft housing, inner chamber loam core volume is all bigger, thereby to make the loam core skeleton according to the concrete shape of handicraft, materials such as loam core skeleton available iron silk, reinforcing bar or cast iron are made, for the gas permeability that guarantees the loam core reaches certain deformability is arranged when pouring into a mould, materials such as some straw can be clogged in inside, loam core, sawdust also are provided with the exhaust passage.
Steady in order to guarantee that alloy liquid fills type, and do not stay the casting gate vestiges at outer surface as far as possible, generally adopt bottom gating.For preventing that slag from flowing into die cavity, also can slag trap be set according to actual conditions, certain feeding technology measure also can be arranged in addition.
The privileged sites of handicraft (as oxtail) are to connect after the casting in addition.After the handicraft integral manufacturing was finished, its surface suitably polished to get final product.
Utilize technology of the present invention successfully to produce imitative golden Bronze Ox in lines and make the copper lion in lines, further proved the feasibility and the economy of this invention for Construction Bank Yunnan Province for Bank of China Yunnan Province.
