Problems solved by technology

[0003] In order to overcome the problems existing in the background technology, the present invention discloses a production method of casting copper sculpture casting production method of casting copper sculpture. Adjust the formula of the mold material under certain conditions to avoid expansion or shrinkage of the wax mold due to temperature changes, and the wax mold will break and shrink. The heating mold shell expands and breaks to ensure the smooth progress of subsequent operations. In the casting operation, the present invention selects 62 brass as the casting raw material. 62 brass has strong strength, sufficient hardness and good plasticity, and is not easy to be cast. Segregation and porosity occur, and the welding performance is good to ensure the production quality of copper carvings

Embodiment 1

[0027] The casting production method of the cast copper sculpture mainly comprises the following steps:

[0028] The first step is to design the drawings, design the drawings according to the overall concept of the sculpture, and cast the sculpture according to the drawings;

[0029] The second step is to make clay drafts and make models according to the design drawings;

[0030] The third step is to remake the mold. The remake of the mold is determined according to the complexity of the work. The simpler works can be remade with plaster, and the complicated ones will be remade with silica gel. The present invention uses silica gel molds; it is characterized in that: In the mold remanufacturing operation, gates, risers, main runners, branch runners, ingates, exhaust risers, hidden risers, slag collection bags, etc. are prepared before mold assembly;

[0031] The fourth step is casting the wax pattern. After the mold is turned over, pour the melted paraffin into the mold that ...

Abstract

The invention relates to a casting production method of a cast copper sculpture, and belongs to the field of handicraft production processes. The casting production method of the cast copper sculptureis characterized in that the formula of mold material is controlled, the formula of the mold material is adjusted under different temperature conditions, expansion or shrinkage of the temperature change of a wax mold is avoided, then the situation that the wax mold is broken and retracted is avoided, meanwhile, the roasting temperature is controlled in the roasting process of a mold shell, the phase change time of the mold shell is delayed, expansion and crushing of the mold shell caused by rapid temperature increase are avoided, smooth proceeding of subsequent operation is guaranteed, and afine and accurate casting result is obtained. In the casting operation, 62 brass is selected as a casting raw material, the 62 brass has relatively strong strength, and has enough hardness and relatively good plasticity, the phenomena of segregation and looseness are not easy to occur, the welding performance is good, and the production quality of the copper sculpture is guaranteed.

Description

technical field [0001] The invention belongs to the field of handicraft production and processing technology, in particular, the invention relates to a casting production method of cast copper sculpture. Background technique [0002] Bronze sculpture is an important part of architectural decorations in China. It has a long history and can be traced back to the Shang and Zhou dynasties. In modern society, copper sculptures are also an important part of architectural decorations. In the field of modern sculpture, copper sculptures occupy a large share of decorations. The weight of the bronze sculpture is becoming more and more important. Compared with the ancient Shang and Zhou dynasties, modern bronze sculptures are generally used for decoration. The production process of modern bronze sculptures meets different decoration needs, and the volume difference is large. With the continuous change of production needs, The production process of copper sculpture is also constantly ch...
