CN203003984U - Novel die cutting die of multi-hole foam product - Google Patents

Abstract

The utility model discloses a novel die cutting die of a multi-hole foam product. The novel die cutting die comprises an upper template, a lower template, a hole punching pin and a spring. The lower template and the upper template are arranged on the die, the hole punching pin is hidden in the upper template, and the spring is arranged at the position of the hole punching pin of the lower template, so that in the process of working and downward motion process of the upper template, the hole punching needle can not be firstly contacted with materials to be stressed, the face of the upper template is firstly stressed and presses the materials, and then the hole punching needle downwards presses punching materials. The number of hole is changed from 17 to 13, an outer contour is reduced for nearly 1/2, and diameters of the holes are changed from 1.5mm to 0.65mm, and a space between every two holes is changed from original 3mm to now 1.5mm. Design of a precedence order of downward motion of the hole punching needle and the upper template is changed, the phenomenon that the diameter is less than 1mm and the space between every two holes is less than 2mm is well avoided, and the die solves the problem that the hole punching pin is easy to deform and damage.

Description

A kind of die-cutting mould of novel porous foam product

Technical field

The utility model relates to a kind of mould, especially relates to a kind of die-cutting mould of novel porous foam product.

Background technology

The foam material is thick and soft, easily be out of shape during cross cutting, the hole is many and be difficult for waste discharge, the new hole of the utility model quantity changes 13 into by original 17, and it is nearly 1/2 that outline dwindles, and all apertures have changed present 0.65mm into by original 1.5mm, pitch of holes has changed present 1.5mm into by original 3mm, because the little spacing in hole is little, hole number is many, and when exposing cope match-plate pattern 2mm design cross cutting according to original perforating needle, perforating needle is easy to distortion.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of prior art, and a kind of die-cutting mould of novel porous foam product is provided.

Realize that the present utility model purpose technical scheme is as follows:

a kind of die-cutting mould of novel porous foam product, comprise: cope match-plate pattern, lower bolster, perforating needle, spring, lower bolster and cope match-plate pattern are set on described mould, perforating needle is hidden in cope match-plate pattern, the perforating needle place of lower bolster is provided with spring, when working like this, cope match-plate pattern is in downward running, just can the first contact material of perforating needle not stressed, but by the cope match-plate pattern face first stressed push down material then perforating needle press down again and punch material, hole quantity changes 13 into by original 17, outline dwindles nearly 1/2, all apertures change present 0.65mm into by original 1.5mm, pitch of holes has changed present 1.5mm into by original 3MM.Thisly changed the design that perforating needle and cope match-plate pattern move downward precedence, well avoided diameter＜1mm, pitch of holes＜2mm has solved the problem of the easy deformed damaged of pin.

The specific embodiment

How further illustrate the utility model below in conjunction with accompanying drawing realizes:

as depicted in figs. 1 and 2, a kind of die-cutting mould of novel porous foam product, comprise: cope match-plate pattern, lower bolster, perforating needle, spring, lower bolster 1 and cope match-plate pattern 2 are set on described mould 3, perforating needle 5 is hidden in cope match-plate pattern, the perforating needle place of lower bolster 1 is provided with spring 4, when working like this, cope match-plate pattern is in downward running, just can the first contact material of perforating needle 5 not stressed, but by the face of cope match-plate pattern 2 first stressed push down material then perforating needle press down again and punch material, hole quantity changes 13 into by original 17, outline dwindles nearly 1/2, all apertures change 0.65 present mm into by original 1.5mm, pitch of holes has changed 1.5 present mm into by original 3mm.

Claims (2)

1. the die-cutting mould of a novel porous foam product, comprise: comprising: cope match-plate pattern, lower bolster, perforating needle, spring, it is characterized in that: lower bolster and cope match-plate pattern are set on described mould, and perforating needle is hidden in cope match-plate pattern, and the perforating needle place of lower bolster is provided with spring.

2. the die-cutting mould of a kind of novel porous foam product according to claim 1 is characterized in that: described lower bolster hole quantity changes 13 into by original 17; All apertures change 0.65 present mm into by original 1.5mm; Pitch of holes has changed 1.5 present mm into by 3 original mm.
