Technical field
The present invention relates to a kind of overlay film moulding process and equipment of composite panel, particularly two-sided overlay film moulding process and the equipment of composite panel.
Background technology
Composite panel is the panel for control operation, such as the key control panel of washing machine, micro-wave oven, on 3C Product, automobile, has use more widely now.By resin base material and the ornament materials that is fixed on substrate resin part surface, formed.Publication number is the Chinese patent of CN101879770B, discloses a kind of injection molding process of composite panel, just discloses a kind of moulding process of one side film.Because ornament materials is made by printing, rich color, the different decoration of pattern can be provided, the decoration of individual layer can not meet market demand, has gradually at the back side of resin base material and also pastes one deck ornament materials, the visual effect of raising composite panel and ornamental.This two-sided composite panel, all on the basis of the composite panel of one side, the ornament materials at the back side is pasted on resin base material by glue, this hand paste of poor quality, often cause dislocation, or be pasted not strongly and cause back side decorative layer to come off, or sticking veneer there is cavity to affect visual effect.
Summary of the invention
For solving bonding insecure, bonding quality is bad, adhesion efficiency the is low problem of diaphragm in prior art, provide a kind of composite panel two-sided overlay film moulding process, this moulding process makes diaphragm be bonded in that the fastness of resin base material is strong, bond locations is accurate, high, the bonding visual effect of bonding working (machining) efficiency is good.
For addressing the above problem, the technical solution used in the present invention comprises:
The two-sided overlay film moulding process of a kind of composite panel, this technique comprises the following steps:
The first step: according to designing requirement, prepare front diaphragm and back side diaphragm, printing pattern layer on front diaphragm and back side diaphragm;
Second step: printing adhesion layer in the patterned layer of front diaphragm and back side diaphragm;
The 3rd step: front side films sheet and back side diaphragm are carried out to preform;
The 4th step: front diaphragm is positioned over to the cover half of mould, and positions;
The 5th step: back side diaphragm is positioned over to the dynamic model of mould, and positions;
The 6th step: injection moulding makes resin base material and the bonding processing that completes composite panel of diaphragm.
In the 3rd described step, the preliminary shaping method of diaphragm is punching and shaping.
Die-cut on diaphragm have a locating hole.
When punching and shaping, diaphragm is heated, make diaphragm be configured as the curved shape basically identical with curved panel.
For solving the problem that present technology bond locations is incorrect, bonding intensity is poor, bonding effect is bad, provide a kind of composite panel two-sided overlay film former, this equipment can realize diaphragm on resin base material accurately bonding, improve bonding effect, improve bonding working (machining) efficiency, bonding visual effect is good.
For addressing the above problem, the technical solution used in the present invention comprises fixed half and moving half, is provided with diaphragm positioner on cover half, is provided with sprue channel open on cover half, it is characterized in that at described dynamic model, placing diaphragm place, the back side offers sprue channel open, is provided with back side diaphragm positioner on dynamic model.
Described diaphragm positioner is: determining the installation alignment pin corresponding with back side diaphragm locating hole on film.
Front diaphragm and back side diaphragm are all printed with to adhesive layer, are placed in injection mold simultaneously, and the back side diaphragm lay down location on dynamic model offers sprue channel open, make front diaphragm and back side diaphragm by an injection moulding, moulding is pasted on resin base material.
By injection moulding, realize the automation of diaphragm and paste, make diaphragm intactly fit in resin base material, can not produce the cavity of binding face, there is deviation in the position that can not produce laminating diaphragm, has greatly improved quality and the visual effect of shaped article, improved productivity ratio.
