Method for manufacturing base steel mould with metal arc spray coating

Abstract

The invention discloses a metallic arc spraying steel-based mold manufacturing method. The metallic arc spraying steel-based mold manufacturing method comprises mold preparation, metallic arc spraying modeling, mold frame manufacturing, mold filling material casting, mold unloading and electric brush degree mold cavity surface polishing treatment, and mold component assembly and mold trial. In the metallic arc spraying modeling process, the consumption of the compressed air is controlled within 1.6 to 2m<3> / min, and the wire feeding speed of the self-consuming electrode wire is controlled within 0.1 to 4.8m / min. The invention has the advantages that the modeling precision of the metallic arc spraying steel-based mold manufacturing method is high, the replicability of the product surface pattern is good, the production efficiency is greatly enhanced, and the modeling precision of the metallic arc spraying steel-based mold manufacturing method is suitable for the new product development and small batch multiple variety production, in particular for the production of steel-based plastic molds, rubber molds and ceramic molds.

Description

Technical field: [0001] The invention relates to a method for manufacturing a mold, in particular to a method for manufacturing a steel-based mold by metal arc spraying. Background technique: [0002] Most of the rapid molding technology is based on the physical model made by rapid prototyping, that is, the sample mold (master mold), and adopts copying methods such as metal spraying, electroplating, composite material casting, precision casting, etc. to quickly manufacture the main working parts of the mold, such as convex, concave molds or mold cavities. , mold core, its manufacturing cycle is short, only 1 / 5-1 / 10 of the traditional CNC cutting method, and the cost is only 1 / 3-1 / 5 of it. [0003] Metal spraying molding method is an indirect molding method that combines rapid prototyping with thermal spraying rapid solidification and other methods. Metal thin layer, then reinforce the backing and remove the prototype to get the mold product, there are two forms at present, ...

Problems solved by technology

[0003] Metal spraying molding method is an indirect molding method that combines rapid prototyping with thermal spraying rapid solidification and other methods. Metal thin layer, then reinforce the backing and remove the prototype to get the mold product, there are two forms at present, that is, the atomization spray method, that is, the rapid solidification process RSP, and the spraying method; the metal spraying molding method is based on the sample mold, and the mold The size of the cavity and the geometric accuracy depend entirely on the surface of the sample cavity and its fine patterns formed at one time, so the mold making speed is fast, the manufacturing cycle is short, the mold life is long, and the cost is low; this method has been reported to be applied to the stamping of automobile panels In the field of mold manufacturing, but there is no mold manufacturing for daily life products and making steel-based plastic molds, rubber molds, ceramic molds, etc., such as flower box base injection molds, shoe sole molds, ceramic blank pressing molds, etc.
