Electric discharge machine for mask mold machining

Abstract

The invention discloses an electric discharge machine for mask mold processing, and belongs to the technical field of mask mold processing. The electric discharge machine comprises a machine body, thebottom of the machine body is provided with a liquid tank, the two sides of the top of the liquid tank are both provided with protruding plates, the tops of the protruding plates are both provided with electric push rods, and the output ends of the electric push rods are provided with moving frames; and a plurality of sets of containing frames are evenly arranged at the bottom ends of the inner sides of the moving frames, and extrusion assemblies are movably connected to the tops of the containing frames. According to the electric discharge machine for mask mold processing, the two sides of the outer portions of mask molds are supported through an arc-shaped containing groove and a pressing frame, and adaptability to the mask molds with different diameters is achieved; and meanwhile, thetops and the bottoms of the mask molds are supported and extruded through a first soft cushion and a second soft cushion, and the friction force between the first and second soft cushions and the topsand the bottoms of the mask molds is increased, so that the mask molds are prevented from rolling and deviating under the influence of electric sparks, the machining accuracy of the mask molds to bemachined is better ensured, and the use rate is increased.

Description

technical field [0001] The invention relates to the technical field of mask mold processing, in particular to an electric discharge machine for mask mold processing. Background technique [0002] A mask is a kind of sanitary product, generally refers to wearing on the mouth and nose for filter Air entering the nose and mouth to block harmful gas , odor , Droplets , Virus It is made of materials such as gauze or paper, and the mask has a certain filtering effect on the air entering the lungs. respiratory infectious disease When it is popular, wearing a mask has a very good effect when working in a polluted environment such as dust. In the process of production, it is generally processed by EDM. [0003] EDM machine, the full name is a kind of mechanical processing equipment, mainly used for electric discharge Sparks Processing, widely used in the manufacture of various metal molds and mechanical equipment, EDM is a special processing method that uses the electric...

Problems solved by technology

[0005] The purpose of the present invention is: in order to solve the existing electric discharge machine when clamping the roll-shaped mask mold, because the mask mold is a roll-shaped structure, so that the mask mold is easily subjected to electricity in the process of processing. Due to the influence of sparks, rolling offset occurs, which makes it difficult to ensure the accuracy of mask mold processing and reduces the utilization rate. Moreover, when the existing EDM machine supports the mask mold, it cannot quickly and accurately replace the new mask mold to be processed , increases the difficulty of work to a certain extent, reduces the problem of work efficiency, and provides an EDM machine for mask mold processing
