Abstract

The utility model pertains to one kind of metal cleaning and slicing composite mold, related to the improvement of cut molding structure of paper cartons in printing and packaging. The wood board is equipped with die cutter, featured by the fact that holes are made on the wood board equipped with hardware elements in the holes; the mentioned hardware elements are in small size and abnormity; the mentioned hardware elements have through holes with cutter point on the top. The appearance and shape of the mentioned hardware elements is not restricted, generally in small size and abnormity. The installation location for the mentioned hardware elements on the wood board is equipped with under waste-cleaning channel and the through holes on the mentioned hardware elements are connected with the channel. The new composite mold greatly expands the application scope of wood mold. Except some positions with high requirement for size and accuracy, for instance, the position in small size and abnormity adopts hardware elements, but most still adopt the wood cutting mold. The composite mold is low in cost but can satisfy the requirement of high tolerance accuracy for general small-sized engineering drawings and low tolerance accuracy for large-sized engineering drawings, so that the wood mold can be really applied in the electronic industry.

Description

Stripping truncation assembling die under the metal

Technical field

The utility model belongs to a kind of mould, particularly to being used for the improvement that printing packaging papery box-like mould is cut into the mould structure of type.

Background technology

Existingly be used for the mould that printing packaging papery box-like mould is cut into type production usefulness, a large amount of usefulness of tradition be plank cutting die (abbreviation wooden model), its structure is, adopts the laser cutting plank earlier, more by hand the die for special purpose cutting knife plank of packing into.The die size precision of this structure is not high, and durability is bad, and the edge of a knife has seam; Owing to do not descend the stripping structure, the place is yielding at the small size abnormity.Wooden model is placed restrictions on by the style of traditional press, can not realize with the outer method of joining mould bases of upper and lower mould (matched molds).The stripping form is subjected to the elastic gum effect that edge of a knife seam is misplaced at small size abnormity place on the wooden model, loses dimensional accuracy.

The five metals punch die that adopts (being called for short the five metals mould) is to adopt with machining process to make now, directly processes the cutter peak, and general five metals mould is to shear severing, and waste material is from former below venting.In electronics auxiliary material industry, be used for pad in die-cut mobile phone, all kinds of household appliances, products such as waterproof, antistatic, radiation proof thin slice, sheet metal, flexible circuitry.Its shortcoming is that the process-cycle is long, and the general five metals mould process-cycle is 10-45 days, the price height, and mould row plate number is few, and the difficulty that repairs a die will begin completely knocked down from mould bases when repairing a die, or goes up grinding machine or laser soldering, or with the line cutting matched molds of reforming, re-assemblies again.

In electron trade, particularly the style pace of change of small household appliances such as mobile phone, MP3 industry is more and more faster at present, and along with the miniaturization day by day of product, and the dimensional tolerance required precision of its each parts of inside is improved day by day.There are edge of a knife seam directly die-cut life-span of influence and precision in the small size place of wooden model, and more and more littler size and tolerance make wooden model can not get approval in the use of electron trade; And five metals mould cost is very high, and the process-cycle is long, and mould supplier's supply of material speed contradiction is become increasingly conspicuous.For example, LCD TV surface brightening piece, when generally making wooden model, small size abnormity place dimensional accuracy can not guarantee; When doing the five metals mould, not only volume is big even can't find large-sized five metals moulding press.

Summary of the invention

The purpose of this utility model is, overcomes the shortcoming of above-mentioned prior art, and stripping truncation assembling die under the metal of a kind of plank cutting die and five metals die component combination is provided.

Stripping truncation assembling die has die-cutting rule under a kind of metal on the plank; It is characterized in that hardware component is equipped with in perforate on the plank in the hole; Described hardware component outward appearance is the small size abnormity; Described hardware component has through hole, and the top is the knife edge.Described hardware component face shaping is not limit, and is generally the small size abnormity.

The installation site of hardware component has down stripping passage on described plank, and the through hole of described hardware component communicates with following stripping passage on the plank.

During the truncation of the utility model combination die, hardware component has through-hole structure, and waste material is squeezed the formation walking by new waste material in through hole when next cross cutting.What combination die adopted is stripping method under the truncation, has not only realized the following stripping that traditional wooden model can not be realized but also do not changed the truncation method, makes combination die simple mode of still complete maintenance wooden model truncation on the cross cutting method.The application of the utility model hardware component, making wooden model realize that part is close-shaped does not have an edge of a knife seam.Hardware component is directly to be processed to form the seamless edge of a knife with machining center, and the processing inwall forms down the stripping passage.Stripping passage UNICOM forms the new stripping structure that is different from the five metals mould under following stripping channel bottom opening and the plank.This structural change the varying sized tolerance of extrusion die cutting knife during the bounce-back of last stripping elastic gum, make simultaneously and forbid on some client's technologies going the requirement of waste material (go up stripping can only manual stripping) in new truncation mode, being achieved by hand.

The utility model makes that the tolerance grade of small size abnormity is demanding to be achieved in combination die.General small size abnormity wooden model can only be accomplished ± 0.15mm, and combination die can reach ± 0.03mm, and long-term die-cut indeformable, and precision still remains unchanged.The utility model production cycle is 2-3 days; Its price is about the 1/4-1/5 of similar five metals mould; When repairing a die, only need the corresponding broken parts of transposing, die-cutting rule or hardware component, and easy to assembly.The utility model is owing to still adopt the truncation method than convenient with machine accent machine on the cutting method of upper and lower mould, and it is wide to use the press type.

In sum, the utility model combination die has been expanded the range of application of wooden model greatly, only at the high position of some dimension precision requirement, for example small size abnormity place adopts the five metals die component, major part is still used plank cutting die form, makes the cost of assembling die not high, but has solved common engineering figure small size tolerance grade height, the requirement that the large scale tolerance is low makes wooden model really can be applied to electron trade.
