Description

Safe type cutter mould

Technical Field

The invention relates to the field of cutter dies, in particular to a safe cutter die.

Background

The cutting of the cutter die is to form the material into customized parts with different sizes by precise processing and cutting according to a preset shape. The die cutting materials for processing include rubber, foamed plastic, vinyl, silicon, metal thin strips, metal thin sheets and other die cutting modes: steel molding: the male and female dies are oppositely punched, and a punch is used, so that the method is suitable for processing the appearance of hard materials.

However, when the existing cutter die is used, because the requirements given by the processed products are different, different cutter heads need to be replaced according to the requirements to process when the cutter is produced, and the existing replacement mode is basically stopped, then the cutter is disassembled for subsequent replacement, which not only influences the working efficiency due to complicated replacement, but also has potential safety hazard when needing to be manually positioned at the lower end of the upper die during replacement, so that a cutter die which can store a large number of cutter bits and freely select the cutter bits to be rapidly replaced when needed is lacked at present, meanwhile, the existing mold lacks a protection function in the process of cutting the cutter when in use, and both hands of a worker are often required to touch the switch simultaneously to prevent the hands of the worker from being hurt by mistake, but the mode can not cut the hands only under the condition of one person, if a plurality of workers still have great potential safety hazards during working, a die which can effectively protect a plurality of workers even if the safety is enhanced is absent at present.
