[0002] The mouth mold is an important part of the molding of the glass bottle mouth. Among all the parts of the glass mold, the structure is the most complex and the precision is the highest. The mouth mold is first in contact with the glass liquid at 1100-1200 °C during the working process, and the mold is opened immediately after the glass bottle is formed. , cycle once in about nine seconds, not only bear the severe thermal shock but also withstand the impact of pressure forming, cold and heat alternating stress, etc., so the general life is short, and it is a vulnerable part

Embodiment 1

[0020] The chemical analysis of electrolytic copper, electrolytic nickel, industrial pure aluminum, industrial pure zinc, crystalline silicon and iron nails is carried out. Firstly, the electrolytic copper and industrial pure zinc are smelted in an intermediate frequency induction furnace according to the mass percentage of 4:1. Copper is used as the master alloy for smelting DH copper alloy in the next step. Prepare the tested master alloy, electrolytic nickel, industrial pure aluminum, crystalline silicon and iron nails according to the ratio of: Ni15%, Al8%, Zn9%, Si1.0%, Mn0.2%, Fe<0.15%, and the rest For Cu and unavoidable impurities. Then put the industrial pure aluminum weighed according to the ratio into the intermediate frequency furnace, wait until the industrial pure aluminum is basically dissolved, then put the electrolytic nickel, wait until the above furnace materials are basically melted, then put the electrolytic copper, crystalline silicon and iron nails Put ...

Embodiment 2

[0022] The charge is weighed according to the following mass percentages: Ni16%, Al10%, Zn10%, Si1.1%, Mn0.2%, Fe<0.15%, and the rest is Cu and unavoidable impurities. The preparation method is the same as in Example 1. Impurities need to be controlled in the finished product: P<0.01%, S<0.01%.

Embodiment 3

[0024] The charge is weighed according to the following mass percentages: Ni14%, Al8%, Zn8%, Si0.9%, Mn0.1%, Fe<0.15%, and the rest is Cu and unavoidable impurities. The preparation method is the same as in Example 1. Impurities need to be controlled in the finished product: P<0.01%, S<0.01%.

[0025] The material composition of the DH copper alloy glass mold die of the present invention is complex white copper, containing Ni, Al, Zn and other elements, and the melting point difference between the alloy elements is large. This problem is well solved by the secondary smelting method, and it can be melted in time. Pre-control the composition of the alloy material. Due to the strong oxidation ability of the copper alloy, the solidification shrinkage is relatively large. The deoxidation and slag removal technology in the ladle greatly reduces the oxidation slag inclusion of DH copper alloy, and the special pouring system is designed by ourselves to solve the problem of shrinkage...

Abstract

The invention discloses a copper alloy glass mold port-die material and a preparation method thereof. The copper alloy is suitable to be used for preparing a glass mold port-die. The copper cloy comprises the components of, by mass, 14-16% of Ni, 8-9% of Al, 8-10% of Zn, 0.9-1.1% of Si, 0.1-0.2% of Mn, less than 0.15% of Fe, and balance of Cu and unavoidable impurities. According to the copper alloy glass mold port-die material and the preparation method thereof, the material has excellent thermal conductivity, oxidation resistance, and high-temperature dimensional stability. With the port-die, glass bottle molding speed is improved, and glass product quality is improved. Also, the service life of the mold is greatly improved. The service life of the port-die with the copper alloy material is higher by 3-5 times than that of cast iron materials.

Description

technical field [0001] The invention relates to the field of glass mold materials, in particular to a DH copper alloy glass mold die material and a preparation method thereof. Background technique [0002] The mouth mold is an important part of the molding of the glass bottle mouth. Among all the parts of the glass mold, the structure is the most complex and the precision is the highest. The mouth mold is first in contact with the glass liquid at 1100-1200 °C during the working process, and the mold is opened immediately after the glass bottle is formed. , about nine seconds cycle, not only to withstand the intense thermal shock but also withstand the impact of pressure forming, alternating stress of cold and heat, etc., so the general life is short, is a vulnerable part. With the development of production technology, the die material has gone through, gray cast iron, molybdenum chromium copper alloy cast iron, 96A cast iron, etc., and developed to the current copper alloy. ...
