Abstract
The utility model relates to a high-hardness casting die with surface chemical-plated nickel-phosphorus alloy. The utility model is characterized in that the die is composed of single layer or more than three layers of composite layer of metal and non-metal material, the surface layer of the die is a nickel-phosphorus alloy layer, the middle layer of the die is a nickel or other alloy layer and the central layer of the die is a macromolecule resin layer. The utility model has the mainly characteristics of material saving, short die making cycles, high wear resistance and long service life and the surface roughness and the dimensional precision of the utility model are in full accord with mother sample dies. The utility model is suitable for manufacturing mould cavities, such as injection, plastic sucking, blow molding, slushing, glue moulds, glass moulds, die casting molds, etc. and electric spark forming electrodes.
Description
Technical field
The utility model belongs to mould manufacturing industry, and particularly a kind of surface is the high hardness casting die of chemical plating nickel-phosphorus alloy.
Background technology
Along with market economy increasing development, impel industrial products more and more to many kinds, high-quality, direction develops cheaply, in order to strengthen the competitiveness of product on market, Products Development cycle, production cycle are shorter and shorter, so to making the critical process equipment of various products---and the requirement of mould is more and more harsher.In addition, intense market competition, the acceleration of model change is reducing cost to mould, and the requirement that improves precision and life-saving aspect will certainly be more and more higher.It can make enterprise win the market, and creates remarkable economic efficiency.
The general die cavity of sand casting mould is bigger, complex structure, and applying working condition is abominable, and molding sand is very serious to the wearing and tearing of mould.The mould and die accuracy and the hardness that adopt conventional method to make are low.Begin the seventies to adopt the electrocasting mfg. moulding die to be used widely, but former electroforming mold materials is a nickel dam, case hardness has only about Hv500, and for a long time the casting mould under molding sand impacts needs the mould of high rigidity.
Summary of the invention
The purpose of this utility model is that the case hardness that exists at above-mentioned mould is not high, the shortcoming that is easy to wear and tear, and it is the high hardness casting die of chemical plating nickel-phosphorus alloy that a kind of surface is provided.
The technical solution of the utility model is achieved in that
The surface is the high hardness casting die of chemical plating nickel-phosphorus alloy, it is characterized by: mould by metal and nonmetallic materials individual layer or more than three layers composite bed form, the superficial layer of mould is the chemical plating nickel-phosphorus alloy layer, the intermediate layer of mould is nickel or its alloy-layer, and the central core of mould is a polymer resin layer;
The surface is the high hardness casting die of chemical plating nickel-phosphorus alloy, it is characterized by: the superficial layer of described mould is the chemical plating nickel-phosphorus alloy layer;
The surface is the high hardness casting die of chemical plating nickel-phosphorus alloy, it is characterized by: the intermediate layer of described mould is the nickel cobalt (alloy) electrodeposited coating;
The surface is the high hardness casting die of chemical plating nickel-phosphorus alloy, it is characterized by: the central core of described mould is epoxy resin or other resin bed.
Main feature of the present utility model is to save material, die manufacturing cycle weak point, wearability is high and the life-span is long, surface roughness, dimensional accuracy and female original mold are in full accord, are applicable to the manufacturing of mold cavities such as injection, plastic uptake, blowing, slush moulding, bakelite mould, glass molds, compression mod and edm forming electrode.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The surface is the high hardness casting die of chemical plating nickel-phosphorus alloy, it is characterized by: mould by metal and nonmetallic materials individual layer or more than three layers composite bed form, the superficial layer 1 of mould is the chemical plating nickel-phosphorus alloy layer, the intermediate layer 2 of mould is nickel or its alloy-layer, and the central core 3 of mould is a polymer resin layer;
The superficial layer 1 of the high hardness casting die of chemical plating nickel-phosphorus alloy is the chemical plating nickel-phosphorus alloy layer;
The surface is that the intermediate layer 2 of the high hardness casting die of chemical plating nickel-phosphorus alloy is the nickel-cobalt alloy plating electrodeposited coating;
The surface is that the central core 3 of the high hardness casting die of chemical plating nickel-phosphorus alloy is epoxy resin or other resin bed.
With the example the technical solution of the utility model that is further elaborated.
Example 1:
Lining 50 μ m chemical plating chemical plating nickel-phosphorus alloy conductive layers form superficial layer on the silicon rubber master mold, and electroformed nickel-cobalt alloy forms the intermediate layer then.After the minimum local thickness of electroforming nickel dam reaches 3mm, under 500 ℃,, adopt epoxy resin that mould inside is carried out backing then and form central core fusing of silicon rubber master mold and removal, make resin and metal shell strong bonded.Promptly obtain complete high hardness casting die.
Example 2:
Lining chemical plating chemical plating nickel-phosphorus alloy layer forms superficial layer on the silicon rubber master mold, after the minimum local thickness of coating reaches 3mm, under 500 ℃, the silicon rubber master mold is melted and removal, adopt epoxy resin that mould inside is carried out backing then and form central core, make resin and metal shell strong bonded.Promptly obtain complete high hardness casting die.
