Embodiment Construction

[0016] The present invention will be further described below.

[0017] Nickel shell mold production process, it includes the following steps:

[0018] Step 1, open the iron mold;

[0019] Step 2, carrying out texture etching to the iron mold;

[0020] Step 3, turn over the female mold of the silicone master mold;

[0021] Step 4, turn over the resin electroforming mold core;

[0022] Step 5, spray conductive paste on the iron mold;

[0023] Step 6, nickel electroforming; electroforming is to deposit metal on the mold by electrolysis to manufacture or reproduce metal products, which can separate the mold from the metal deposit, and transfer the metal nickel from nickel balls or nickel cakes to the mold through a DC power supply Surface, with the accumulation of time, the thickness of the nickel layer on the surface of the mold reaches a thickness of 3-5 mm;

[0024] Step 7, the iron mold is washed;

[0025] Step 8, remove the mold core;

[0026] In step 9, the nickel she...

Abstract

The invention relates to the technical field of die production, in particular to a production process for a nickel-shell die. The production process comprises the steps that an iron die is opened, texture etching is conducted on the iron die, a female die of a silicone female die is overturned, a resin electroformed die core is overturned, conductive paste is sprayed on the iron die, nickel electroforming is conducted, the iron die is washed, the die core is removed, mechanical machining of the nickel-shell die is conducted, and a finished product of the nickel-shell die is prepared. According to the production process, the delivery time is greatly shortened, and the cost is significantly reduced.

Description

technical field [0001] The invention relates to the technical field of mold production, in particular to a nickel shell mold production process. Background technique [0002] With the vigorous development of the automobile industry, people have put forward higher requirements for the comfort of the car, and more and more hard plastic parts have been replaced by soft plastic imitation leather. In the production process of soft plastic parts, the nickel shell mold is one of the indispensable molds in the production process. Due to the characteristics of itself and the production line, the mold life of nickel shell molds in the production of soft plastic parts is not long (about 25,000 molds), resulting in a very large demand and a large market size. Due to the high difficulty and complexity of manufacturing nickel shell molds, there is no domestic manufacturer to manufacture them, and they all rely on imports. There are only 5 manufacturers capable of producing nickel shell ...
