Problems solved by technology

However, practice has proved that the manual thermal spraying process has large porosity and low bonding strength with the base material, which cannot make a good combination of nickel-based alloy and copper alloy, and is easy to fall off after being used on the machine, which cannot meet the requirements of bottle manufacturers. , so it poses a technical challenge for glass mold manufacturers

Embodiment 1

[0022] Take a glass mold with a maximum cavity diameter of 25±0.05mm and a height of 30±0.05mm as an example.

[0023] A) Cavity pre-processing, preferably but not limited to choose the model VT160AN / 2P vertical machining center produced and sold by Ningxia Little Giant Co., Ltd. in China. The silicon-copper alloy cast by the previous process is the mold blank of the base material matrix. The cavity is milled, and the surface cortex in the cavity is milled. During the milling process, a 1mm welding position (welding position or welding position) is expanded outward around the cavity, so that the maximum diameter of the cavity becomes smaller. It is 27mm and the height is 32mm. Three grooves are set at intervals of 8mm in the height direction of the cavity. The width of each groove is 1mm and the depth is 0.45mm. The bonding strength (mortise and tenon effect) of the base metal matrix (silicon-copper alloy base material matrix) is combined, and all sharp corners of the groove a...

Description

technical field [0001] The invention belongs to the technical field of glass mold processing, and in particular relates to a method for filling a nickel-based alloy in a cavity of a glass mold with a silicon-copper alloy as a parent material matrix. Background technique [0002] In order to effectively prolong the service life of glass molds made of heat-resistant iron alloy castings, nickel-based alloy powder is usually sprayed into the easily damaged glass mold cavity by manual thermal spraying process (oxyacetylene flame spraying) to form nickel-based alloy powder. alloy layer. Because nickel-based alloys have good corrosion resistance, oxidation resistance, and thermal fatigue resistance, the method of spraying nickel-based alloy powder into the cavity of the glass mold can undoubtedly prolong the life of the glass mold. However, since the base material for making glass molds is heat-resistant iron alloy castings, and the Achilles heel of heat-resistant iron alloy casti...
