Description
Technical field
The utility model belongs to plastic film processing technique field, relates to a kind of blanking units, especially relates to a kind of plastic film appearance curved surface blanking units.
Background technology
In in-molded (IMD) process, after the thermoforming of plastic printing diaphragm, the finishing degree of accuracy of abnormal curved surface outline edge, directly can affect the presentation quality of product after injection mo(u)lding.And usual adopted abnormal curved surface profile repaiies blanking method at present, the technical problem existed is: the size that cannot calculate the displaypattern before diaphragm thermoforming exactly, therefore, just need when trimming operation to adopt multiple tracks mould die-cut, but also constantly to improve the die-cut size of correction, this can increase the difficulty of processing of plastic film greatly, causes the working (machining) efficiency of product low, and affect the qualification rate of final products, production cost is increased greatly.
Application number is the Chinese utility model patent of 201020655242.1, discloses a kind of film cutting device, and this device comprises base; Can to be arranged on up or down on base, for the cutting die of die-cut film, described film cutting device also comprises and is arranged on base, is positioned at backing plate below cutting die, and this backing plate comprises the fixed head that is fixedly installed on base and removably laminates the plastic adjustable plate be arranged on above fixed head.The major advantage of the film cutting device designed by this patent is when plastic adjustable plate surface has more tool marks, only need change plastic adjustable plate, without the need to changing fixed head, thus economize on resources, but the service condition of this device is limited, can not be used for repairing plastic film abnormal curved surface outline edge, cannot accurately locate, be difficult to the die-cut quality ensureing plastic film edge.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and provide a kind of structure simple, die-cut accurate plastic film appearance curved surface blanking units.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of plastic film appearance curved surface blanking units, this device comprises mounting plate, pop-up gusset piece, die cutting die, guide pillar and bedplate, described pop-up gusset piece is a pair, be separately positioned on the arranged on left and right sides of mounting plate, described die cutting die is arranged between mounting plate and bedplate, described guide pillar is arranged on bedplate, and mounting plate and bedplate is linked up through die cutting die.
Described die cutting die comprises concave template, punch retainer and limiting gasket, and described punch retainer is arranged on bedplate, and described concave template is positioned at the top of punch retainer, and described limiting gasket is arranged between concave template and punch retainer.
Described limiting gasket is arranged on the lower surface of concave template by bolt.
The upper surface of described punch retainer is provided with the punch adopting high carbon alloy steel to be made.
The lower surface of described concave template is provided with the die adopting high carbon alloy steel to be made.
Described die and punch are in manufacturing process, and after heat treatment, process of hardening, long service life, can ensure the stability of the dimensional accuracy of punching products.
When manufacturing and designing die and punch two critical piece, the rule that Main Basis abnormal curved surface height rises and falls, accomplishes one_to_one corresponding by shape between the two, guarantees that the die-cut edge of a knife of die and punch has fit clearance stable, symmetrically.Employing guide pillar can ensure the guiding quality of fit between die and punch, and limiting gasket can limit the shut height ensureing mould, avoids the die-cut edge of a knife damaging die and punch.
During operation, the mounting plate of blanking units is fixed on the upper surface of stamping machine, and bedplate is fixed on the work top of stamping machine, adjusted by guide pillar and place punch retainer and concave template, then, the plastic film after hot forming is placed on punch retainer, starting switch, namely by the upper and lower die-cut action of die and punch, complete the appearance curved surface of plastic film die-cut.
Compared with prior art, the utility model has following characteristics:
1. change and needed test of many times to determine the cooked mode of die-cut size in the past, the test period shorten design, manufacturing, can cost of manufacture be reduced, the raising of product processing quality can be ensured again;
2. the scope of application is comparatively wide, once accurately can complete the clicking technique of abnormal curved surface outline edge, can be extended in the processing of other similar-type products;
3. structure is simple, practical, safe and reliable, and dismounting and maintenance are conveniently.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment:
As shown in figures 1-4, a kind of plastic film appearance curved surface blanking units, this device comprises mounting plate 1, pop-up gusset piece 2, die cutting die, guide pillar 8 and bedplate 5, pop-up gusset piece 2 is a pair, be separately positioned on the arranged on left and right sides of mounting plate 1, die cutting die is arranged between mounting plate 1 and bedplate 5, and guide pillar 8 is arranged on bedplate 5, and mounting plate 1 and bedplate 5 is linked up through die cutting die.
