Abstract
A producing method of an in-mold pasted film is disclosed. The method includes steps of: printing a pattern on a film sheet, punching and shaping the film sheet, covering a hot-pressing mold cavity with an elastomer, performing injection moulding, and the like. The surface of a plastic part is covered with the film sheet by an injection moulding manner, and the film sheet is disposed in the mold cavity in advance, and is melted into one part with high-temperature melt plastic during injection molding to form firm combination, so that the plastic part has advantages of scratch resistance, strong corrosion resistance, long service lifetime, and the like.
Description
Technical field
The present invention relates to a kind of Shooting Technique, particularly relate to pad pasting production method in a kind of mould.
Background technology
In order to make working of plastics have various design and color, and the surface of working of plastics is protected.Traditional method brushes one deck paint at plastic part surface, and because paint is through exposing to the weather for a long time, pattern easily comes off, and life period is shorter, and service life is not long.
Summary of the invention
The object of the present invention is to provide that a kind of damage resistant, corrosion resistance are strong, pad pasting production method in the mould of long service life.
For achieving the above object, technical solution of the present invention is:
The present invention is pad pasting production method in a kind of mould, comprises the following steps:
(1) printed patterns on diaphragm: the diaphragm of selected specific thicknesses and hot strength, then uses specific ink to carry out pattern printing to diaphragm as requested;
(2) diaphragm punching molding: open corresponding 2D die cutting die according to the requirement of product and carry out die-cut to the diaphragm be completed for printing;
(3) hot pressing die die cavity covers elastomer: carry out bed die surface to hot pressing die and boil glue, cover one deck elastomer at hot pressing die die cavity, boiling glue thickness is 1-5 millimeter;
(4) injection mo(u)lding: diaphragm put into hot pressing die die cavity and fixedly secure, injection mo(u)lding temperature is 150-250 DEG C, and diaphragm baking time is 4-15 second.
In hot pressing injection molding process, use middle pressure 60-75%, middle low speed 40-60%, dwell time 10-20 second more than.
In step (4), injection mold does corresponding trapezoidal diaphragm locating mechanism, and the shape corresponding with molding mold cavity according to diaphragm is contained in the diaphragm of forming in molding mold cavity.
After adopting such scheme, because the present invention covers one deck diaphragm by the mode of injection moulding at plastic part surface, this diaphragm is arranged in mold cavity in advance, when injection moulding, the molten plastic of this diaphragm and high temperature can merge, form one firmly to combine, working of plastics is had advantages such as damage resistant, corrosion resistance are strong, long service life.
Working of plastics after this method process has following characteristics:
1, aging to product surface of ultraviolet is prevented; 2, the coating of product surface is prevented to be subject to the destruction of external force; 3, preventing cleaning product surface is that wiping to product surface comes off; 4, solvent can be prevented the damage of product surface coating, prevent the scuffing of product surface, reach the degree of more than 3H.5, pattern stereoscopic impression is strong, dust and moisture, and ability of anti-deformation is strong, and design and color can arbitrarily change.
The present invention is further illustrated for specific embodiment below.
Detailed description of the invention
The present invention is pad pasting production method in a kind of mould, comprises the following steps:
1, printed patterns on diaphragm: the diaphragm of selected specific thicknesses and hot strength, then uses specific ink to carry out pattern printing to diaphragm as requested.
2, diaphragm punching molding: open corresponding 2D die cutting die according to the requirement of product and the diaphragm be completed for printing is carried out die-cut (if before diaphragm prepattern or negligible amounts can open 2D blanking die electronic cutting equipment can be used to cut diaphragm).
3, hot pressing die die cavity covers elastomer: carry out bed die surface to hot pressing die and boil glue, cover one deck elastomer at hot pressing die die cavity, play the effect of protection like this at ensuing hot-forming diaphragm, generally boil the thickness of glue at 1-5 millimeter.
4, arrange detent mechanism: on injection mold, arrange corresponding trapezoidal diaphragm locating mechanism, then corresponding with molding mold cavity according to diaphragm shape is contained in the diaphragm of forming in molding mold cavity.According to surperficial 3D structure and the appearance and size of product, inner hollow location is adopted to ensure that diaphragm does not offset with the upper and lower translation activity together with core rod of periphery pilot pin, or the mode (snap fit face must not higher than mold parting line otherwise can mould be damaged by pressure) adopting product structure (product hollow location) and surrounding slide block snap fit to locate when ensureing injection moulding resin overflow to membrane surface, diaphragm is wrapped to inside resin.Root
5, injection mo(u)lding: diaphragm put into hot pressing die die cavity and fixedly secure, injection mo(u)lding temperature is 150-250 DEG C, diaphragm baking time is 4-15 second, carrying out hot-forming temperature for PET sheet according to the surface of product and structural requirement to diaphragm is be set in about 180 degree, if diaphragm baking time is generally will relatively lengthen in the 4-7sec sheet material larger heat time, the hot-forming time is generally more conducive to shaping in mould of diaphragm like this more than 12.In hot pressing injection molding process, use middle pressure 60-75%, middle low speed 40-60%, dwell time 10-20 second.To note positioning diaphragm otherwise there will be diaphragm drift condition simultaneously.
Key technology:
1, diaphragm printing: design and color can be needed to print diaphragm by different level according to guest, 7 layers of chromaticity printing technology can be accomplished, heat insulation adhesion ink is printed in main employing in the end one deck, this ink adopts thermoplastic resin and metal ink and other components to be combined together diaphragm diaphragm and plastic material when injection moulding that can make to print and is bonded together completely, and the impact and the high temperature resistant diaphragm printing-ink that prevents that play anti-injection pressure during injection moulding are rushed film.
2, enter to water mode: adopt a direction multiple spot hook angle slip into cover diaphragm parallel enter glue or reversing mould hook angle from middle multiple spot and slip into and cover diaphragm and enter to water mode, can prevent like this into watering red ink and diaphragm gauffer and diaphragm crimping.
Emphasis of the present invention is just: diaphragm is inserted mold cavity before injection moulding.
The above, be only present pre-ferred embodiments, the chromatography number of plies of diaphragm can be determined according to needs, therefore can not limit scope of the invention process with this, namely the equivalence done according to the present patent application the scope of the claims and description changes and modifies, and all should still remain within the scope of the patent.
