Bronze drum directly molded by virtue of resin sand casting and method for molding bronze drum

Abstract

The invention provides a bronze drum directly molded by virtue of resin sand casting and a method for molding the bronze drum. The method comprises the steps of preparing a bronze drum model which is already carved with related patterns according to requirements, preparing a casting material, namely a resin sand raw material, by taking common quartz sand or emery as a major raw material and casting resin as an auxiliary material, finally, manufacturing a bronze drum model slot by use of a conventional method, and then casting a bronze drum casting which is smooth and flat in surface, clear in patterns and clear in profile. The method has the advantages that as the bronze drum model is already carved with the related patterns, the manufactured bronze drum model slot is printed with the related patterns, and therefore, the cast bronze drum casting can directly form the bronze drum with the finished patterns. After the resin sand as the casting material is solidified and molded, no sand falls down from the surface of the formed model slot, the surface is kept smooth and flat, and then the surface of the cast bronze drum is also relatively smooth and flat. The process links of grinding, carving, printing patterns and the like for the bronze drum casting are omitted, so that the labor intensity is greatly reduced, the production cost is further reduced and the economic benefit of the finished bronze drum is also improved.

Description

technical field [0001] The invention belongs to the technical field of musical instrument preparation, and in particular relates to a bronze drum directly molded by resin sand casting and a method thereof.

Problems solved by technology

In addition, there is no engraving or printing on the surface of the traditional bronze drum, and it is often engraved or printed on the bronze drum after casting.

Therefore, the traditional copper drum production process is not only complicated but also cumbersome
