Description

Low noise cutting mould

Technical field

Plastics processing of cutting technical field is the utility model is related to, more particularly to a kind of low noise cutting mould.

Background technology

In order to process plastic film class product, it usually needs required shape is cut out from plastic foil by cutting mould Shape.Cutting mould bolster whole face collision in the past used is found in actual production, noise is very big, makes work climate noise It is miscellaneous, influence worker's notice.Collide at the same time and die wear can be caused to accelerate, it has to using the mould of Steel material, and this mould Have that requirement on machining accuracy is high, and acquisition cost is hundreds thousand of easily, scrap that cost is too big, very influence the competitiveness of enterprise.

The utility model is just to provide for a kind of new mould structure to solve the above problems.

Utility model content

The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of low noise cutting mould, including cope plate And lower template, lower template are equipped with cushion block and some limit holes positioned at feeding area both sides, cope plate, which is equipped with, is located at feeding area Interior cutter and the position-limited needle of corresponding limit hole, the upper surface of cushion block are higher than the upper surface of lower template.

Specifically, the position-limited needle is in the column on pinnacle.

Specifically, the cutter is a kind of diaphragm type cutter that can be pulled down from cope plate.

Further, the cope plate aluminium is as material.

Specifically, the lower template is equipped with the cushion towards cutter.

Specifically, the cushion block can be disassembled from lower template.

Further, the cushion block is fixed in lower template by multiple fixed screws.

Further, the lower template is equipped with the cushion towards cutter, and cushion is clamped in lower template by two cushion blocks On.

Using above-mentioned technical proposal, the beneficial effect of technical solutions of the utility model is：

1st, the utility model utilizes cushion block, not only realizes the guiding to plastic foil, but also reduces collision area, reduces Processing noise, extends die life, saves maintenance cost.

2nd, diaphragm type cutter can be replaced according to the actual needs of working width and machining shape, and universality is good.

3rd, cope plate changes comparatively cheap aluminum into, and scrap cost is than relatively low.

4th, cushion block is set independently of lower template is also beneficial to reduce scrap cost.

When the 5th, processing the plastic foil of different in width, what cushion block can also be replaced according to actual processing demand.

6th, the cushion block that screw is fixed has been also convenient for the fixation of cushion.

Embodiment

The utility model is described in further detail with reference to specific embodiment.

Embodiment：

As shown in Figures 1 to 4, a kind of low noise cutting mould of the utility model, including cope plate 1 and lower template 2, under Template 2 is equipped with cushion block 21 and some limit holes 22 positioned at feeding area both sides, and cope plate 1 is equipped with cutting in feeding area The position-limited needle 12 of knife 11 and corresponding limit hole 22, the upper surface of cushion block 21 are higher than the upper surface of lower template 2.Position-limited needle 12 is in pinnacle Column, for ensuring aligning for cope plate 1 and lower template 2 in molding.Because cushion block 21 is located at the both sides of feeding area, institute Itself can play the role of guiding plastic foil conveying.When complete molding, cope plate 1 can only contact the upper table of cushion block 21 Face, without having entire collision with lower template 2, therefore processing noise substantially reduces, and abrasion reduces, and also extends mould use In the service life, save maintenance cost.

As shown in Figure 1 to Figure 3, cutter 21 is a kind of diaphragm type cutter that can be pulled down from cope plate 1, and cope plate 1 is selected Aluminium is as material.Diaphragm type cutter is attached on cope plate 1, can according to the actual needs of working width and machining shape into Row is replaced, therefore universality is more preferable.Because cope plate 1, there will be no large area collision, wears obvious drop with lower template 2 Low, cope plate 1 can make comparatively cheap aluminum into from general Steel material, and scrap cost is also than relatively low.

As shown in figure 4, cushion block 21 can be disassembled from lower template 2, cushion block 21 is fixed on by multiple fixed screws 23 In lower template 2.Cushion block 21 is as the component that can be collided, it is easier to wears, it sets independently of lower template 2 and is also beneficial to reduce Scrap cost.In addition, the width between two cushion blocks 21 is related with 21 structure of cushion block, so the plastic foil of processing different in width When, cushion block 21 is also that can be replaced according to actual processing demand.But the fixed form of cushion block 21 is not limited to screw and fixes one kind.

As shown in Figure 1 and Figure 4, lower template 2 is equipped with the cushion 24 towards cutter 11, and cushion 24 is pressed from both sides by two cushion blocks 21 Hold in lower template 2.The machining area of plastic foil is always propped up on cushion 24 in general processing, during molding, cutter 11 can switch to the inside of cushion 24 always, and such plastic foil can be ensured that cut-out, and cushion block 21 facilitates cushion 24 Fixation.

Above-described is only some embodiments of the utility model.For those of ordinary skill in the art, On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to this practicality New protection domain.
