Description

Technical Field

[0001] The utility model relates to the technical field of electric spark cutting, in particular to a wire cutting device used for mold processing. Background Art

[0002] In the production process of molds, cutting and forming is an important link. As a sample mold for the formation of other products, its precision requirements are relatively high. It is not enough to use only traditional tool cutting methods. Electric spark wire cutting is widely used nowadays. It has high precision and low loss. It uses high-temperature electric spark melting to achieve precise cutting of metal. During the process, cutting fluid and deionized water and other liquids are used to immerse the wire body to prevent electric sparks from splashing. At the same time, it also allows the molten metal surface to quickly cool and form.

[0003] Currently available wire-cut EDM equipment is basically equipped with enclosures, but most of the enclosures have openings on the back. Since the installation rod of the cutting wire needs to extend into the enclosure, the cutting fluid can easily splash out from the opening at the rear of the enclosure during the process, causing a large amount of liquid splashing and pollution in a short time, and there is a lack of certain protective design.

[0004] In order to solve the above problems, we have made improvements and proposed a wire cutting equipment for mold processing. Utility Model Content
