Automatic scrap-cleaning forming mould

Abstract

The invention discloses an automatic scrap-cleaning forming mould. The automatic scrap-cleaning forming mould comprises an upper mould and a lower mould. The upper mould comprises an upper template, on which multiple scrap-cleaning needles, multiple punches and multiple air-exhaust windows are arranged. End portions of free ends of the punches are provided with elastic ends made by elastic material. The upper mould and the lower mould are oppositely arranged. The lower mould comprises a lower template. Material-falling windows corresponding to the scrap-cleaning needles are arranged on the lower template. Pressure relief grooves are arranged corresponding to the punches in the lower template. Pressure relief pads made by elastic material are arranged in the pressure relief grooves. The thicknesses of the pressure relief pads are not greater than the depths of the pressure relief grooves.The automatic scrap-cleaning forming mould has following beneficial effects: the automatic scrap-cleaning forming mould is capable of integrating two procedures including scrap cleaning and separation of die-cutting edges at the bending part on the same set of forming moulds so that technology is improved and procedures are reduced; production efficiency is increased; in the meantime, manual labor of separation of die-cutting edges is saved; and manual cost is reduced.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a molding die for automatically removing waste from die-cut packaging boxes. Background technique [0002] figure 1 Shown is a schematic diagram of the assembly of four cigarette wrapping papers 30 that have been die-cut. The bent piece 33 at the portion 32 is bonded to the cigarette wrapping paper at the die-cutting edge. In the process of folding the cigarette wrapping paper 30 into a cigarette wrapper by a charter machine, it is first necessary to remove the waste at the waste part 31 , and then separate the die-cutting edge at the bending part 32 . Usually, most of the above-mentioned waste removal and die-cutting edge separation are done manually, which has high labor intensity, high labor cost and relatively low efficiency. Although there are currently some molds that can automatically remove waste, the separation of the die-cutting edges in the bending part is still do...
