Embodiment Construction

[0031] Such as Figure 1 to Figure 10 Shown is a process diagram of the in-mold coating process for plastic products in which the injection molding and film coating of plastic products can be completed simultaneously in one molding process provided by the present invention, and the process diagram for the in-mold coating Schematic diagram of the structure of the molding die for the process. In-mold coating process for plastic products, including the following steps:

[0032] 1) Make a film forming module 1, and set the installation slideway 4 of the film forming module 1 between the die 2 and the punch 3 of the forming mold;

[0033] 2) attaching the film 5 to the die 2 and positioning;

[0034] 3) Clamp the mold for the first time, install the film forming module 1 on the installation slideway 4, and then move the film forming module 1 to cooperate with the concave mold 2 to form the film 5 onto the on the die 2;

[0035] 4) For the second mold clamping and injection mold...

Abstract

The invention discloses an in-mould film lamination process for a plastic product and a forming mould for the in-mould film lamination process. The invention provides the in-mould film lamination process for the plastic product, which can simultaneously finish injection moulding and film lamination operation of the plastic product in a one-time forming process; and the invention also provides theforming mould for the in-mould film lamination process. The in-mould film lamination process for the plastic product comprises the following steps of: arranging a film forming module on the forming die, forming a film on a female mould of the forming mould through the film forming module before injection moulding, and then performing injection moulding so that the film lamination and the injection moulding are finished at the same time and the film has good attachment on an injection moulding part. In order to ensure smooth implementation of the in-mould film lamination process, the inventionalso provides the forming mould comprising the film forming module, a film cutter module and a movable slipway for mounting the film forming module and the film cutter module.

Description

technical field [0001] The invention relates to an in-mold film coating process, in particular to an in-mold film coating process for plastic products; the invention also relates to a forming mold for the in-mold film coating process. Background technique [0002] With the development of the times and the progress of society, customers have higher and higher requirements for the appearance quality of electronic products, and they are also more and more novel. The quality of product appearance has a direct impact on the market sales of products. At present, the technology of coating the outer surface of electronic injection molding products generally adopts the secondary processing of the parts, that is, the parts are coated with a coating tool after the parts are formed. The disadvantage of this film coating technology is that there are problems such as poor adhesion, foaming, and film wrinkling, which seriously affect the surface quality of the parts, so that the appearance...
