Abstract
The utility model provides an in-mould-decoration (IMD) material pressing and forming mould which comprises a movable mould and a fixed mould. The movable mould comprises an ejection plate, a movable mould core and a movable mould platform. The ejection plate and the movable mould core are fixed mutually, the movable mould core is sleeved in the movable mould platform in connecting mode and can move longitudinally relative to the movable mould platform, and the fixed mould comprises a fixed mould core and a fixed mould platform. The IMD pressing material forming mould is characterized in that the parting surface formed by the movable mould platform and the fixed mould platform is a stepped parting surface. In a material pressing and forming process, a membrane can be tightened well, and the IMD material pressing and forming mould prevents a thin film from wrinkling and cracking in a forming process, improves qualified rate of products, and increases tensile strength of the products.
Description
Technical field
The present invention relates to a kind of in-mold decoration and use mould, more specifically, relate to a kind of in-mold decoration and use the binder mould.
Background technology
IMD is a decoration technique inside mold; It is one of surface decoration technique that is in fashion at present both at home and abroad, surface sclerosis transparent membrane, and the decorating film that after its binder moulding, will print forming is put into injection mould; With the back side of resin injection, make resin and film integrator then at form film.The bottom surface of IMD product is a film, and printed patterns is in the centre, and the back side is injection molded layers, has avoided product because of its surface damage causes the fuzzy of printed layers, can keep for a long time its inner printed patterns be not worn, colour-fast.
Yet, when using conventional I MD binder mould, shown in Fig. 3 a, owing to form straight die joint between cover half platform and the dynamic model platform; Behind dynamic model and the cover half matched moulds, in the film forming process, mould is undesirable to the tension effect of film; Cause the side of film that wrinkling and phenomenon drawing crack are arranged, influence the qualification rate of product behind the film forming, and its stretching is height-limited; Like Fig. 5 a, the stretching height H of film ' can not surpass 20mm, big limitations the realization of this kind technology on various products.
Summary of the invention
The objective of the invention is to overcome above deficiency, a kind of IMD binder mould is provided, make it in the binder forming process; Can play tension effect preferably to diaphragm; Avoid the wrinkling and drawing crack phenomenon in the film forming process, improve product percent of pass, increase the stretching height of product.
The technical scheme that the present invention solve the technical problem employing is:
A kind of IMD binder mould; Comprise dynamic model and cover half, said dynamic model comprises top board, mavable module core and dynamic model platform, and said top board and mavable module core are fastened to each other; Said mavable module core is socketed in the dynamic model platform and can vertically moves with respect to the dynamic model platform; Said cover half comprises cover half Renhe cover half platform, it is characterized in that, said dynamic model platform and the formed die joint of said cover half platform are the step portion profile.
Further, said dynamic model is a punch, and said cover half is a die.
Further, said mavable module core has the land area that forms to the curved surface of outer projection by, said cover half benevolence have by one with the corresponding land area that forms to the die cavity of inner recess of said curved surface.
Preferably, said step portion profile comprises first plane parallel to each other and second plane, and the inclined-plane that is connected between first plane and second plane.
Preferably, the angle on said inclined-plane and said first plane or second plane is 145 °.
Further, the height on said inclined-plane is 8mm ~ 10mm.
Further, the degree of depth of the land area of said cover half benevolence is 40mm.
The beneficial effect of the utility model is:
(1) the IMD binder mould of the utility model is better to compressing with tension effect of thin-film sheet, and diaphragm is stressed more even during the binder moulding.
(2) use the IMD binder mould of the utility model, can improve the stretching height of the form film that processes.
(3) be widely used, go for the application of more products.

The specific embodiment
Combine the specific embodiment that the utility model is at length explained, preferred embodiment described herein only is used for explanation and explains the utility model, and is not used in qualification the utility model at present.
Shown in Fig. 3 b, the IMD binder mould of the utility model comprises dynamic model 1 and cover half 2; Dynamic model 1 comprises top board 3, mavable module core 4 and dynamic model platform 5; Top board 3 is fastened to each other with mavable module core 4, and mavable module core 4 can be movable relatively with dynamic model platform 5, and cover half 2 comprises cover half benevolence 7 and cover half platform 6.Dynamic model platform 5 is the step portion profile with cover half platform 6 formed die joints; This step portion profile comprises first plane parallel to each other and second plane; And the inclined-plane that is connected between first plane and second plane; First plane of this inclined-plane and step portion profile or the angle on second plane are 145 °, and the height on inclined-plane is 9mm.
Film 8 is positioned over before moulding on the cover half platform 6 of cover half 2, and after being heated, dynamic model 1 moves downwards, and is by dynamic model platform 5 and cover half platform 6 that film 8 is fixing earlier, makes film 8 moulding through moving downward of mavable module core 4 again.Because dynamic model platform 5 is better with 6 pairs of film 8 fixations of cover half platform, makes film 8 stressed more even, has guaranteed the qualification rate that form film is higher, and can improve the height that stretches, like Fig. 5 b, the stretching height H can reach 40mm.
