Abstract

The utility model relates to a silica gel pattern mould for gilding, composed of a metal pattern mould and a silica gel layer adhered on the metal pattern mould, wherein, the metal pattern mould can be a copper plate or a zinc plate. A master mould which is made of bakelite powder, melamine, urea, etc. is pressed by a metal pattern mould with a smooth mould thread surface, and the silica gel layer is formed by adhering the master mould on the metal pattern mould in a thermal pressure way. The silica gel pattern mould which is used for gilding can obtain typeface and / or pattern with a smooth surface, and can obtain clear and refined pattern; a thin and soft metal plate can be adopted for gilding and printing products with an arc structure.

Description

A kind of silica gel template of gold stamping usefulness

The utility model relates to a kind of silica gel template of gold stamping usefulness.

Along with the progress of industrial society, various plastic products increase day by day.For making plastic product more attractive in appearance,, generally scald and go up some floral designs or name of product etc., to reach the effect of attractive in appearance and propaganda in the appearance of plastic products (for example cosmetics close) perhaps for trade mark, the name of product of outstanding company.Yet generally the gold stamping metallic plate of seeing on the market of using is mainly made with copper or zinc.This copper coin or zine plate are burnt next decorative pattern, title etc., and following shortcoming is arranged:

1), cause the surface non-homogeneous, so the literal and the decorative pattern that stamp out with copper coin or zine plate such as can produce and writing is unintelligible uneven at phenomenon because plastic product itself often has the shrink phenomenon.And because of copper coin, zine plate is nonelastic, so the plastic product breakage rate is high in gold stamping process.

2) next gold stamping with copper coin, zine plate or other metallic plate, then gold stamping area is big more, and the phenomenon uneven and that writing is unclear of burning next decorative pattern or font is even more serious.

3) if boiling hot thin font or thin decorative pattern then more can produce unintelligible and even fuzzy phenomenon.Generally use printing or paster in this case instead.Yet printing effect is naturally not as good as gold stamping attractive and durable, and paster also easily comes off, damages.

4) it is gold stamping to utilize the common metal plate to carry out, and destroys the smooth surface of original plastic product easily.

5) because metallic plate is hard, so the series products that can't close plastic bottle, plastic tank or the lipstick with radian carries out thermoprint.

All shortcomings in view of the gold stamping plate of above-mentioned metal, the purpose of this utility model provides a kind of novel gold stamping template, described template is that silica gel is inserted master mold, with metallic plate hot-press gluing moulding, this template not only can not be destroyed the smooth surface of plastic product, and the font that stamps out or floral designs are very even and clear.

Another purpose of the present utility model provides a kind of novel silica gel template, and this silica gel template can be burnt level and smooth, fine and smooth font or pattern having on the plastic product of radian.

Another purpose of the present utility model provides a kind of high temperature resistant and whippy gold stamping silica gel template of using.

The silica gel template of gold stamping usefulness described in the utility model is a kind of metallic plate that is bonded with layer of silica gel, and described metallic plate can be copper coin or zine plate.Because layer of silica gel is that thermocompression bonded invests on the described metal form in the master mold (the master mold raw material is phenolic moulding powder, melamine, urea etc.) that the ganoid metal form of mould line is pressed into, so its surface is very smooth, the decorative pattern that stamps out does not have the lines of processing.Again because the kind specific character (seeing below) of silica gel, so but itself DE of mat during thermoprint is done suitable processing to depth lines, make the very clear exquisiteness of decorative pattern, pattern or font.In addition, during thermoprint planar shaped goods, available thicker metallic plate; When thermoprint has the goods of arcuate structure, available softer thin metallic plate.

This silica gel template is compared with traditional template, has following advantage:

Hear resistance and weather resisteant are good, hot stamping effects is good, font that stamps out or decorative pattern, the lines that does not have machined, do not destroy the smooth surface of plastic product, although and font or decorative pattern depth difference, its definition is still identical, make that the decorative pattern exquisiteness stamp out is attractive in appearance, and can also thermoprint have the plastic product of radian.

Description of drawings is as follows: Fig. 1 is the outside drawing of the utility model; Fig. 2 is the cutaway view of the utility model; Fig. 3 is for scalding the plastic product schematic diagram of system decorative pattern with silica gel template described in the utility model.

Below in conjunction with all accompanying drawings, describe the silica gel template of gold stamping usefulness described in the utility model in detail.

Consult Fig. 1 and Fig. 2, silica gel template described in the utility model is to be glued together in hot-forming mode by metallic plate (1) and layer of silica gel (2) to form.

The material of metallic plate (1) does not have particular requirement, and can be depending on the shape of printing thing.If print the planar shaped plasthetics, can select thicker and hard metallic plate for use, the unbending characteristic of this metallic plate of mat guarantees that the planar shaped decorative pattern or pattern or font printed seems clear.If be printed with the plasthetics of arcuate structure, then can adopt the softer and thin metallic plate of quality, such as aluminium metal sheet, the softer flexible characteristic of mat metallic plate quality is to reach the purpose of printing clear decorative pattern, pattern or font on arcuate structure.Therefore, the material of metallic plate can be selected according to various different situations.

Layer of silica gel (2) is made for the silica gel raw material.So select the silica gel raw material, be because silica gel itself contains very strong-Si-O-Si-key, so have a numerous characteristics: such as hear resistance splendid (can be heat-resisting to 320 ℃, and general gold stamping temperature required be 200 ℃-250 ℃), and can under thermoprint high temperature, still maintain flexibility and elasticity; Weatherability is good, and is strong for the repellence of oxygen, ozone, sunshine etc., is imprinted on any depth on the silica gel plate and tiny literal and all can not change because of extraneous factor; Silica gel has splendid dielectric property, makes it be subjected to the influence of temperature and supply frequency to reduce to minimum, so when electric heating scalds system, can not change the performance of die body; Silica gel also has not viscosity and surface of good release property, and the therefore boiling hot decorative pattern and the font of coming of making is very fine and smooth; The good permeability of silica gel makes the literal of the system of scalding keep best definition.We can say that the utility model is based on the characteristic of silica gel itself.

Scald plastic products processed with silica gel pattern mould described in the utility model, scald the exquisiteness of font, decorative pattern or the pattern made, be various gold stamping usefulness templates of the prior art can not than.

Claims
