Description

Technical Field

[0001] The utility model relates to the technical field of laser knife molds, in particular to a laser knife mold with a temperature reduction and cooling function. Background Art

[0002] Laser knife die is a die that cuts shapes. It is used for stamping. The normal structure is composed of a substrate and a steel blade. The substrate is usually made of multi-layer wood, but transparent plexiglass (acrylic board) and plastic board can also be used instead.

[0003] However, the existing laser knife die substrate does not have a cooling structure, which results in the steel blade above the laser knife die substrate being unable to be quickly cooled down after heat treatment or heat generated by continuous stamping friction. Continuous high temperature can easily shorten the service life of the steel blade and also affect the processing efficiency. Therefore, it does not meet the existing needs. We have proposed a laser knife die with a cooling function. Utility Model Content

[0015] 1.
