Glass mold double-metal neck ring mold and preparation method thereof

Abstract

The invention discloses a glass mold double-metal neck ring mold and a preparation method of the glass mold double-metal neck ring mold. The preparation method comprises the steps of cleaning and drying the surface of a copper alloy substrate and the surface of a nickel-based alloy block by using a cleaning solvent to obtain a clean copper alloy substrate and a clean nickel-based alloy block; andleading the cleaned copper alloy substrate and the cleaned nickel-based alloy block into a cabin, enabling the outer circle surface of the portion, facing one side of an inner cavity of the copper alloy substrate, of the nickel-based alloy block to be attached to the surface of the inner cavity, and then vacuumizing and heating the cabin, applying pressure in the direction of the inner cavity to acavity of the nickel-based alloy block in a diffusion welding mode, and keeping the pressure to ensure that the nickel-based alloy block is combined with the inner cavity of the copper alloy substrate as an independent component through diffusion welding and is integrated with the copper alloy substrate. The resistance to high temperature, oxidation, creep, instant heat shock and abrasion of thenickel-based alloy block can be comprehensively embodied, and requirements for the high machine speed of a glass mechanical forming machine are met. Advantages of the copper alloy substrate and advantages of the nickel-based alloy block are ensured, the operation intensity is reduced, and precious metal materials are saved.

Description

technical field [0001] The invention belongs to the technical field of glass molds and their preparation, in particular to a bimetallic die for a glass mold, and also relates to a preparation method thereof. Background technique [0002] As known in the industry, the glass mold is an important equipment for manufacturing glass containers, and the mouth mold is an important part of the glass mold assembly to control the mouth of the glass container. , sleeves and punches, etc., and the outside, that is, the side facing away from the inner cavity, is matched with the initial mold. Therefore, among all the parts of the complete set of glass molds, the matching surfaces of the die are the most, and the precision requirements are strict. Strict, relatively complex structure. Also, because in the manufacturing process of glass containers, the temperature of the glass melt can only be taken out from the initial mold when the temperature of the glass melt drops from 1000°C to about...

Problems solved by technology

Although a certain metallurgical bond can also be produced between the copper alloy base material and the nickel-based alloy insert during the casting process, the degree of this metallurgical bond often depends on the direct temperature between the nickel-based alloy and the base metal, so in this patent teaching Under the same pouring conditions, the preheating temperature and pouring temperature between different batches of nickel-based alloys and base metals cannot be completely consistent, so in the actual production process, the junction of nickel-based alloys and copper alloy base metals will Cracks frequently appear. Although artificial repair welding (repair) can be carried out, there is a large difference between the repair welding material and the matrix and the inner structure of the base metal at the repair welding place, which will often become the final cause of die fatigue failure. source

Secondly, since the casting method described in the aforementioned patent is combined with mortise and tenon, three additional tenons of nickel-based material are required on the side of the nickel-based alloy, and the price of the nickel-based alloy is very expensive, which is not conducive to the control of the production cost of the die
