Embodiment Construction

[0021] A kind of method of V-method molding process casting production glass mold blank, concrete process steps are as follows:

[0022] 1) Blank material: adopt the heat-resistant alloy cast iron material independently developed by our company as AD-VTFe-20-F to cast glass mold blanks. The chemical composition of the heat-resistant alloy cast iron is: C 3.3% ~ 3.8%, Si 1.9%~2.5%, Mn 0.5%~0.6%, P 0.06%~0.07%, S 0.02%~0.03%, Mo 0.5%~0.9%, V 0.1%~0.2%, Ti 0.2%~0.4%, Cr 0.1 %~0.2%, Mg 0.002%~0.004%, Cu 0.1%~0.2%, Zn 0.003%~0.004%, Al 0.03%~0.04%, Ni 0.4%~0.6%, and the rest is Fe;

[0023] 2) Form plate and mold core: adopt the overall aluminum alloy form plate designed and processed by our company; each V-method vacuum pumping box upper box is equipped with 4 freely replaceable form cores, and each form core has 2 half-piece assembled mold cores. The shape of the mold core can be combined with multiple aluminum alloy modules of different parts and sizes according to the shape an...

Abstract

The invention discloses a method for casting and producing glass mould roughcast by a V-process molding process. The method comprises the following processes: casting glass mould roughcast by adopting a heat-resistant alloy cast iron material; assembling aluminum alloy mould cores on replaceable mould board cores and finishing the cores; respectively placing replaceable mould board cores in an upper sand box and a lower sand box of a vacuum sand box; carrying out film laminating; carrying out film roasting; carrying out vacuum pouring; carrying out thermal treatment, and the like. According to the method, the mould roughcast, with a D-type graphite form in a roughcast inner cavity part and A-type graphite forms in other roughcast outer parts, is obtained by methods of carrying out process control and boiler-front inoculation treatment, adding alloy elements such as Mo, V, Ti, Cr, Cu and Al, adopting chilled iron cores and the like. The A-type graphite form structure has good static and dynamic strength, higher thermal conductivity and stable processing performances; the D-type graphite form structure has better compactness and higher tensile strength, and is remarkably improved in wear resistance, heat resistance, oxidization resistance and thermal fatigue resistance; and the mould roughcast with different graphite-form structures on key parts is glass mould roughcast which is most suitable for a glass bottle tank forming process.

Description

technical field [0001] The invention relates to the technical field of glass mold casting castings, in particular to a method for producing glass mold blanks by casting with a V-method molding process. Background technique [0002] Glass molds are an important part of the production process of daily-use glass products and one of the key elements in the molding of glass products. Daily-use glass products have good chemical stability and do not chemically react with their contents. At the same time, because they are made of glass raw materials that melt at a high temperature above 1500°C and can be melted and reused repeatedly, they are internationally regarded as the safest and most environmentally friendly. Food and pharmaceutical packaging materials. In recent years, with the continuous improvement of the living standards of Chinese residents, the demand for daily-use glass products is also increasing. While the output of glass products is increasing year by year, due to ...
