Sectioning casting method for copper artwork

Abstract

The invention discloses a sectioning casting method for a copper artwork. The method comprises the following steps: (1) arranging wax sheets on a plaster mold; (2) arranging a cushion block in a surrounding way at the outer part of the plaster mold; (3) filling resin sand into a wax mold and the upper surface of the cushion block; (4) after the resin sand is cured, reconditioning the side surface, in contact with the wax sheets, of the resin sand until the side surface is at the same plane with the side surfaces, far away from the plaster mold, of the wax sheets so as to form a parting surface; (5) arranging a plurality of steel tubes on the surface of the resin sand and covering the steel tubes by using the resin sand so as to form an early form of a box body; (6) turning over the early form of the box body by 180 degrees until the bottom of the box is upwards, subsequently removing the plaster mold, throwing parting sand, and reconditioning to ensure that the turned-over upper surface is at the same plane with the surface of the upper wax sheet; (7) after the resin sand is cured, separating a plurality of resin sand blocks formed among the wax sheets, and getting out the wax sheets; (8) splicing and molding the resin sand blocks, fastening and pouring high-temperature liquid copper metal to prepare the copper artwork. The method disclosed by the invention has the effects of being convenient to operate and low in production cost.

Description

technical field [0001] The invention relates to a manufacturing method of copper handicrafts, in particular to a split casting method of copper handicrafts. Background technique [0002] As a commonly used handicraft, copper handicrafts are very common in daily life, and copper handicrafts are often large in shape, so that it is often difficult to cast them once in the production preparation process, and because of the large mold, making production The cost is also greatly increased. [0003] Therefore, it is an urgent problem to be solved by the present invention to provide a split casting method for copper handicraft with relatively convenient operation, low production cost and easy operation. Contents of the invention [0004] In view of the above-mentioned prior art, the purpose of the present invention is to overcome that the shape of copper handicrafts in the prior art is often large, so that if it is casted once during the production and preparation process, it is ...
