Embodiment 1

[0017] Below take the PVC plastic women's sole injection mold as an example to illustrate the arc spraying forming process of the present invention:

[0018] The process of shoe sole mold: directly use the real shoe sole or sample mold to make a silicone mold, and then make a ceramic spraying base, spray the mold cavity surface on the base, make a metal frame, fill it with a mixture of metal particles and epoxy resin, concave and convex Mold separation and mold surface cleaning and polishing, machining mold parts, and finally assembling and testing molds.

[0019] Take the PVC plastic female shoe sole injection mold as an example to describe in detail. The sample mold is the original PVC plastic female shoe sole that is popular in the market; determine the parting surface of the mold according to the product requirements, and apply the release agent and release agent The release agent and release agent should be painted evenly, and each brush should be applied after the last b...

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, ...
