Embodiment 1
[0025] Put copper, nickel, zinc, aluminum, silicon, iron, manganese and other metals and part of the returned charge into the electric furnace, heat the electric furnace to about 1100-1300 degrees, and after it is completely melted, install a graphite mold at the discharge port below the electric furnace. , Through the horizontal continuous casting process, pull out the copper alloy round bar, and the laboratory detects the metal content. After the hardness is qualified, it enters the annealing process, and then the metal oxide is peeled off by the peeling machine, and then the CNC cutting machine is used to cut out the slightly heavier than the product. Small section, copper alloy small section is put into the electric heater pipe and heated to about 650-950 degrees, put into the forging machine, install the mold of the product, apply lubricating oil, forge forming, cut the flash after cooling, make the mold pictographic blank, and then measure The hardness is guaranteed, the ...

The invention discloses a novel manufacturing method of a copper alloy glass mold, and relates to the field of copper alloy glass mold material manufacturing, and the novel manufacturing method comprises the following steps: 1, putting a metal raw material and a part of foundry returns into an electric furnace, heating the electric furnace, and after the metal raw material is completely molten, installing a graphite crystallizer mold at a discharge port below the electric furnace; secondly, the metal raw materials are pulled out through a horizontal continuous casting technology to become copper alloy round bars; and thirdly, part of the copper alloy round bars are fed into a laboratory to detect the metal content and hardness, and after the copper alloy round bars are tested to be qualified, the annealing process is conducted. Compared with a sand casting process, the casting process has the advantages that the efficiency is improved, raw materials are saved by about 40%, the density is improved, the product quality is improved, the precision is improved, the surface is smooth and easy to process, the energy consumption is reduced, equipment is easy to operate, the product weight is reduced by about 40% compared with the sand casting process, and the machining allowance is reduced; the novel manufacturing method of the copper alloy glass mold can bring great revolution to the glass mold manufacturing industry.
Description
technical field [0001] The invention relates to the field of manufacturing copper alloy glass mold materials, in particular to a novel manufacturing method for copper alloy glass molds. Background technique [0002] The existing copper alloy glass mold materials are imported alloy copper ingots, containing copper, nickel, zinc, aluminum, silicon, iron, manganese and other elements. [0003] Existing glass mold manufacturers buy imported copper alloy copper ingots and add them to the electric furnace to melt, and use the traditional sand casting process to produce mold blanks. The specific process is to pour molten metal water into the mold cavity, cool and solidify, To obtain the product, in order to form a cavity in the sand mold that matches the shape of the casting, the model must first be made of wood or aluminum. After the sand casting is formed, the pouring die must be cut off. The pouring die is heavy and wastes a lot of money. Material, the rough cast by sand castin...
