Mold cutting tool and manufacture method thereof

Abstract

The invention discloses a mold cutting tool comprising a bottom plate and a cutting tool body, wherein the bottom plate is made of a metal material and is provided with a cutting tool containing gap, and the cutting tool ridge of the cutting tool body is fixed in the cutting tool containing gap. In the manufacture method of the mold cutting tool, the bottom plate made of the metal material is adopted, the cutting tool containing gap is machined on the bottom plate so as to intensify the strength of the bottom plate, and the cutting tool body and the bottom plate can be more stably and tightly combined. When the mold cutting tool is stressed when being used, the cutting tool containing gap has small possibility of widening because of deformation, thereby increasing the stability of the cutting tool body under the working state, improving the mold cutting precision of the mold cutting tool so as to prolong the service life of the mold cutting tool, reducing links of filling up the cutting tool, supplementing the cutting tool, changing the cutting tool and the like in the operation process, and improving working efficiency. Meanwhile, because the mold cutting tool is combined by machining by steps, machining cost and machining complexity are far lower than those of the integral machining of a graver or a etching knife, and thus production cost is lowered while mold cutting precision is guaranteed in the use process.

Description

technical field [0001] The invention relates to the technical field of die cutting knives, in particular to a die cutting knife which adopts a base plate made of metal and installs a knife body through a knife slit on the base plate to improve die cutting precision and a manufacturing method thereof. Background technique [0002] Die-cutter has both the functions of mold and knife. It can cut off or press out the folding marks of the product. It has a wide range of applications and can be used for printed matter, plastic sheet, insulation board of electronic products, leather and other thin sheets and sheet materials. [0003] In the printing and packaging industry, die-cutting is a necessary subsequent process. The method of use is to clamp the die-cutting knife in the die-cutting plate frame of the die-cutting machine, and transport the product to the die-cutting platform through the operation of the die-cutting machine. The cutting die is subjected to pressure from the eq...

AI Technical Summary

Problems solved by technology

The die-cutting accuracy of the engraving knife and etching knife can reach ±0.1mm, but because the processing of the die-cutting knife itself is relatively complicated, its production cost and use cost are high, and it cannot be widely used
