Abstract
The invention provides a nickel shell production technology. The nickel shell production technology comprises the following steps that a die model is made, a die core is made, then electroforming is conducted, the female die is taken out, the nickel shell is taken down from a resin layer after being washed by high-pressure water, and then a nickel shell finished product is obtained. By means of the nickel shell production technology, technical steps are greatly shortened, the cost is reduced, the obtained nickel shell product is easy to achieve die separation, in addition, an iron die is used for replacing a wood die, the generated waste liquid is less, and waste absorption equipment is equipped, the nickel shell production technology also has a positive meaning on the environment and the ecology, and in addition, the product prepared through the method has the advantages that the thickness is controllable, no joint occurs, and the grain similarity reaches 90%.
Description
Technical field
The present invention relates to mould production technical field, especially relate to a kind of nickel shell production technology.
Background technology
Flourish along with automobile industry, the comfortableness of people to automobile is had higher requirement, the flexible plastic of the simulated skin of increasing hard plastic materials and parts replaced. in the production process of flexible plastic part, nickel shell mould is one of requisite mould in its production link, difficulty and the complexity of nickel shell Making mold are very high, traditional production technology is: CNC wooden model---leather is coated---silica gel turns over mould---resin turns over master mold---resin master mold is repaired---------spraying conductive paste---washing---nickel electroforming---washing------other machinings of nickel shell mould---the nickel shell mould finished product that removes core rod that turns over resinous electricity mold core that turns over silica gel master mold former, the overall step of above technique is more, and flow process is got off, the time used is longer, efficiency is low, texture similarity is low, thickness is uncontrollable, and mould and product are not easily separated, use timber as template also not environmentally.
Summary of the invention
For solving the problems of the technologies described above, the present invention proposes a kind of nickel shell production technology, comprising the following steps:
A, analogue formation: select steel or iron as master mold, carry out sanding and polishing, texture as requested, master mold marks texture, on texture, blueing glue is coated with according to marked texture, acid solution is kept 1-2 hour on master mold, iron plate or punching block corrosion is formed texture, finally blue glue is removed;
B, making core rod: configuration resin solution, fall resin solution on master mold, leave standstill after 6-8 hour, hardening of resin, at master mold surface formation resin core rod;
C, electroforming: master mold, the nickel rod of having resin core rod are communicated with dc source, after the surperficial coating conductive paste of master mold, once wash, master mold and nickel rod being placed in after washing fills in the container of nickel chloride solution, carry out cell reaction, after 7-10 hour, observe the nickel shell that master mold By Electrolysis obtains, when reaching the thickness of needs, stop electrolysis;
D, the master mold in c to be taken out, use after high pressure water washing, nickel shell is taken off from resin bed, namely obtains nickel shell finished product.
Preferably, in electroforming process, be provided with air-suction cover at upper vessel portion, use blower fan air-breathing, collection will be discarded.
Preferably, described nickel rod is connected with DC power anode, and described master mold is connected with described power cathode.
Preferably, talcum powder is added in described resin solution.
Preferably, described blue glue thickness is 1-2 centimetre.
Preferably, described direct current power source voltage is 1.5-2v.
The nickel shell production technology that the present invention proposes has following beneficial effect: this technique substantially reduces processing step, provide cost savings, the nickel shell product obtained is easy to mould and is separated, and substitutes wooden model with swage, and the waste liquid produced is few, and be furnished with suction obsolete equipment, also be have positive meaning for environment and ecology, in addition, the product thickness that this method obtains is controlled, do not produce seam, texture similarity reaches 90%.
Detailed description of the invention
Below in conjunction with detailed description of the invention, illustrate the present invention further.
Embodiment
The present invention proposes a kind of nickel shell production technology, comprise the following steps:
A, analogue formation: select steel or iron as master mold, carry out sanding and polishing, texture as requested, master mold marks texture, on texture, blueing glue is coated with according to marked texture, acid solution is kept 1-2 hour on master mold, iron plate or punching block corrosion is formed texture, finally blue glue is removed;
When making master mold, a small amount of acid solution can be produced, the sodium hydroxide solution of dilution can be adopted to carry out neutralizing rear discharge, can not environmental pollution be caused.
B, making core rod: configuration resin solution, fall resin solution on master mold, leave standstill after 6-8 hour, hardening of resin, at master mold surface formation resin core rod;
C, electroforming: master mold, the nickel rod of having resin core rod are communicated with dc source, after the surperficial coating conductive paste of master mold, once wash, master mold and nickel rod being placed in after washing fills in the container of nickel chloride solution, carry out cell reaction, after 7-10 hour, observe the nickel shell that master mold By Electrolysis obtains, when reaching the thickness of needs, stop electrolysis; Compared with electroplating with routine, its washing needed for water consumption considerably less, in full production situation, cupric/silver and nickeliferous cleaning waste water generation are respectively about 10 tons/month, are about about 10PPM containing nickel ion concentration, be a kind of comparatively clean production technology.
D, the master mold in c to be taken out, use after high pressure water washing, nickel shell is taken off from resin bed, namely obtains nickel shell finished product.
Preferably, in electroforming process, be provided with air-suction cover at upper vessel portion, use blower fan air-breathing, collection will be discarded, because nickel electrotyping bath temperature remains on about 50 DEG C, produce a small amount of water vapour waste gas.
Preferably, described nickel rod is connected with DC power anode, and described master mold is connected with described power cathode, both positive and negative polarity.
Preferably, talcum powder is added in described resin solution.
Preferably, described blue glue thickness is 1-2 centimetre, can effectively prevent texture to be corroded, realize the corrosion of texture.
Preferably, described direct current power source voltage is 1.5-2v.
This programme is: drive swage---texture etching---------spraying conductive paste---washing---nickel electroforming---washing------other machinings of nickel shell mould---the nickel shell mould finished product that removes core rod that turns over resinous electricity mold core that turns over silica gel master mold former, compare in background technology, greatly reduce technical process.
To be apparent for those skilled in the art to the multiple amendment of embodiment, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
