Embodiment Construction

[0029] (1) Carving totems on wax blocks to make bronze drum mother molds;

[0030] (2) Use silica gel or can replace silica gel material to pour on the mother touch to make copper drum silica gel mold;

[0031] (3) inject the wax liquid into the silicone mold cavity, open the mold after cooling and take out the wax model;

[0032] (4) Brush glass water and quartz powder coatings (or utilize other binders and refractory materials that replace them) on the surface of the wax model, sprinkle sand (quartz sand or utilize refractory materials that can replace it) to form a shell, Let the mold shell dry and harden, and repeat the process several times until a mold shell with a certain thickness is formed.

[0033] (5) Heat the shell to about 600 degrees.

[0034] (6) Pour molten copper into the shell being heated.

[0035] For example: the method of making a bronze drum with a surface diameter of 41 cm:

Abstract

The invention relates to a technological method for producing music bronze drum through hot mould casting. With the method, a music bronze drum which can provide the modern equal temperaments can be cast. The method comprises steps that: (1) a music bronze drum template (female mould) is manufactured; (2) a music bronze drum mould is manufactured; (3) liquid wax is injected into the cavity of the mould; the liquid wax is cooled, the mould is opened, and the wax mould is fetched; (4) a paint is brushed on the surface of the wax mould; sand is scattered on the wax mould, such that a mould casing is formed; the mould casing is dried and hardened; the processes are repeated several times, until a mould casing with a certain thickness is obtained; (5) the mould casing is heated; (6) liquid copper is injected into the mould casing being heated.

Description

Technical field [0001] The invention relates to a process method of hot mold casting musical bronze drums. Background technique [0002] The technology that has been or is currently being used is the cold sand mold casting copper drum process. The method is: first make a copper drum mold, including a base, an outer sleeve, a drum body mold, an inner cylinder sleeve, a drum surface mold and a mold cover. It is characterized in that the longitudinal section of the disc base is in a "convex" shape, and the cylindrical inner sleeve is vertically installed in the center of the disc base. The cylinder body is lower than the drum body mold, and the upper end is sealed. The drum body mold is vertically installed on the "convex" shaped disc base centered on the inner sleeve. The drum body module is two pieces, which are fan-shaped butt-jointed and surrounded. The cylindrical outer cylinder is vertically sleeved on the shoulder of the "convex" shaped disc base, and its cylinder body...
