CN203141591U - Film cutting die - Google Patents

Abstract

The utility model relates to a film cutting die which comprises a base plate, a die group and a knife. The die group is arranged on the base plate and includes a plurality of die bodies in array. The knife is arranged along a film feeding direction of the die group longitudinally. A guide slot for reciprocation of the knife is arranged, corresponding to the knife, on the base plate. Since the knife is arranged at the front end of the die group and is 0.2-0.5 mm higher than a die cutter, during film cutting, the die cutter and the knife work simultaneously to cut off films synchronously, and subsequent manual operations including waste discharging and trimming are omitted. Accordingly, the film process is short, the productivity is high, the product quality is improved and the percent of pass is increased.

Description

The film blanking die

Technical field

The utility model relates to a kind of mould, is specifically related to a kind of film blanking die.

Background technology

Film is a kind of special physical form, because it is small-sized on this specific direction of thickness, just surround and watch the amount that can survey, and on thickness because the existence at surface, interface, the material continuity is interrupted, make thin-film material produce the special performance different with bulk material thus.

Along with the progress of science and technology and consumer improve for the standard that requires of product durability, the shell of general article, automobile, household electrical appliances, consumer electronic product etc., except the surperficial and changeable multicolour pattern of shell external coating high glaze, also quite exquisite for wearability and the chemical resistance of aforementioned application and pattern.Yet during as wearability and chemical-resistant hard containment vessel, regular meeting forms the crack in the bend of shell with heat reactive resin, and its wearability and chemical-resistance are inferior.

Be wearability and the chemical resistance that reaches case surface, and the bend that is not easy to shell forms the requirement in crack, prior art many with the decorative film for it, most film needs to make through locally-shaped, secondary stamping-out moulding once, the employed blanking die of its secondary stamping-out moulding as shown in Figure 1, by base plate be located on this base plate, arrange the set of molds that forms by a plurality of die ontologies and constitute.But, become wrapped configuration mostly through the stamping forming film of mould, still need and want could use after artificial waste discharge, the cutting edge, so the processing procedure of film is long, production capacity is low, directly have influence on the lifting of efficient, quality and the product fine rate of production.

The utility model content

The utility model purpose is that a kind of film blanking die is provided in order to overcome the deficiencies in the prior art, and by the improvement of structure, the processing procedure of film is short, production capacity is high, improves product quality and qualification rate.

For achieving the above object, the technical solution adopted in the utility model is: a kind of film blanking die, comprise base plate and be located on this base plate, arranged by a plurality of die ontologies the set of molds that forms, described film blanking die comprises also and the described set of molds cut-off knife that front and back arrange on the direction of feed of film that the position corresponding to described cut-off knife on the described base plate is provided with for the reciprocating gathering sill of described cut-off knife.

Further technical scheme, the spacing between described cut-off knife and the set of molds is 3 ~ 5mm.

In the technique scheme, described die ontology be provided with the mould cutter all around, described cut-off knife is higher than described mould cutter 0.2 ~ 0.5mm and arranges.

In the technique scheme, described set of molds is arranged by 8 die ontologies and is formed.

Because the utilization of technique scheme, the utility model compared with prior art has following advantage:

The utility model is provided with cut-off knife at the front end of set of molds, and cut-off knife is higher than mould cutter 0.2 ~ 0.5mm and arranges, during die-cut film, mould cutter and cut-off knife are worked simultaneously, the turned off in synchronization film, thereby no longer need follow-up artificial waste discharge and cutting edge, the processing procedure of film is short, production capacity is high, improves product quality and qualification rate.

Description of drawings

Below in conjunction with accompanying drawing technical solutions of the utility model are described further:

Accompanying drawing 1 is the front view of prior art film blanking die;

Accompanying drawing 2 is the front view of the utility model embodiment one;

Accompanying drawing 3 is the partial enlarged drawing at A place among Fig. 2;

Wherein: 1, base plate; 10, gathering sill; 2, set of molds; 20, die ontology; 3, cut-off knife.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Accompanying drawing 2 and Fig. 3 are a kind of film blanking die described in the utility model, comprise base plate 1 and are located on this base plate 1, arrange the set of molds 2 that forms by 8 die ontologies 20.

Described film blanking die comprises also and described set of molds 2 cut-off knife 3 that front and back arrange on the direction of feed of film that the position corresponding to described cut-off knife 3 on the described base plate 1 is provided with the gathering sill 10 that pumps for described cut-off knife 3.

In the present embodiment, described cut-off knife 3 is located at the 3mm place, the place ahead of described set of molds 2.

Described die ontology 20 be provided with the mould cutter all around, described cut-off knife 3 is higher than described mould cutter 0.3mm and arranges.

Because the utilization of technique scheme, the utility model compared with prior art has following advantage:

The utility model is provided with cut-off knife at the front end of set of molds, and cut-off knife is higher than mould cutter 0.3 mm and arranges, during die-cut film, mould cutter and cut-off knife are worked simultaneously, the turned off in synchronization film, thus no longer need follow-up artificial waste discharge and cutting edge, the processing procedure of film is short, production capacity is high, improves product quality and qualification rate.

Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.

Claims (4)
