Embodiment Construction

[0021] figure 1 , figure 2 , image 3 A preferred embodiment of the invention is shown.

[0022] see figure 1 , figure 2 and image 3 As shown, in this embodiment, the in-mold decoration injection molding mold is a one-out two mobile phone back cover injection mold. The mold cavity 3. The difference between this mold and ordinary molds is that the front mold 1 and the rear mold 2 extend from the position of the largest outer surface 8 of the product on both sides of the mold cavity along the mold opening direction to have an insertion surface 4, and then extend forward from the insertion surface 4. The penetration surface 5 of the mold and the rear mold, the penetration surface 4 and the penetration surface 5 constitute the parting surface of the mould. The front mold is distributed with four concave ears 6 around the mold cavity on the collision surface 5 extending from the insertion surface 4. The bottom surface of the concave ears 6 is flush with the largest outer ...

Abstract

The invention relates to an in-mold decoration and injection molding mold and an in-mold decoration and injection molding method using the injection-molding mold. The invention aims at solving the problem that an insert is easy to fall out of a mold cavity when placing the film insert and provides the in-mold decoration and injection molding mold which comprises a front mold and a back mold. The front mold and the back mold form the mold cavity for product molding and are provided with an inserting through surface by extending from the largest profile surface of the product along the opening mold direction, a hitting through surface of the front mold and the back mold is extended from inserting through surface, and the inserting through surface and the hitting through surface form a parting surface of the mold. The invention also provides the in-mold decoration and injection-molding method, comprising the following steps: providing a film; forming a decoration pattern layer on the film; cutting the film; pre-forming the film into the film insert; placing the film insert for injection molding.

Description

technical field [0001] The present invention relates to an injection molding mold, more specifically, to an in-mold decoration injection molding mold in which an insert is provided in a mold cavity during injection molding, and an in-mold decoration injection molding method using the injection molding mold . Background technique [0002] Injection Molding for In-Mold Decoration (IMD) technology combines technologies and methods such as film printing, preforming and injection molding. The surface of the finished product has a layer of transparent plastic film to protect the underlying printed pattern from scratches and make the pattern durable. Therefore, this technology has gradually replaced the traditional methods of spraying directly on the object, pad printing and water plating. And the fineness of the pattern of the products using this technology is better than the traditional processed products. [0003] The main step of the in-mold decoration injection molding metho...
