Problems solved by technology

At present, the method used to remove metal mold cores generally adopts acid or alkali corrosion method, but its disadvantages are mainly slow removal rate, generation of harmful gas to human body, and large amount of acidic or alkaline chemical waste. Such waste increases production costs and poses a risk of environmental pollution

Abstract

The invention discloses an electrolytic corrosion device for metal mold core demolding of a micro-sized shell-layer type part. The electrolytic corrosion device comprises a cathode system which can move in the X-axis direction and the Y-axis direction, an anode system which is used for positioning and clamping an anode workpiece and can move in the Z-axis direction and can do rotary movement, a flowing-speed-controllable electrolyte circulation and filtration system which is used for circulation, filtration and heating of an electrolyte, and an ion concentration online monitoring system used for monitoring metal ions of the electrolyte, during processing, the anode workpiece and a nozzle of a cathode are in an inclined state, the anode workpiece is positioned obliquely above the nozzle ofthe cathode, under the action of a direct-current pulse power supply, the corrosion voltage is controlled, a metal mold core of the micro-sized shell-layer type part is removed through electrolyte erosion corrosion, and then the shell-layer type metal part is obtained. According to the device, the defects that the common chemical corrosion is low in efficiency and heavy in pollution are overcome,the production efficiency is improved through electrolytic corrosion, and the advantage that the electrolyte can be recycled and is green and environment-friendly is achieved.

Description

technical field [0001] The invention relates to the field of electrolytic corrosion processing, in particular to an electrolytic corrosion processing device used for removing metal mold cores in the manufacturing process of micro-sized shell-type parts. Background technique [0002] In the manufacture of micro-sized shell-type parts, due to the limitation of the size, structure and shell thickness of the parts, the direct molding method cannot be used in general, and the core demoulding technology is used. The specific steps are: metal core preparation→ Shell plating → metal mold core demoulding. At present, the method used to remove metal mold cores generally adopts acid or alkali corrosion method, but its disadvantages are mainly slow removal rate, generation of harmful gas to human body, and large amount of acidic or alkaline chemical waste. Such waste increases production costs and presents a risk of environmental pollution. Therefore, it is necessary to adopt a techno...
