Problems solved by technology

[0004] The existing IMR technology usually uses a roll feeding device to feed the foil, and sends the pattern to be transferred into the cavity between the second mold and the fixed mold. When transferring, it is necessary to use vacuum adsorption to make the foil film stick to the fixed mold. On the parting surface, since the edge of the product usually has a bend, during the injection molding process, when the molten plastic fills the cavity, the surface of the product is prone to irregularities due to factors such as foil bulging at the bend of the product. Flatness affects the quality of finished products and increases the defect rate of products to a certain extent

Embodiment 1

[0033] Please refer to Figure 1 to Figure 4 , the embodiment of the present invention provides an in-mold transfer system, including an injection molding mechanism 30, and the injection molding mechanism 30 includes a first mold device 31 and a second mold device 32 arranged opposite to each other.

[0034] Wherein, the first mold device 31 includes a first mold body 311 , and a first parting surface 312 is provided on a side of the first mold body 311 opposite to the second mold device 32 . In this implementation, the first parting surface 312 is a composite parting surface, which has at least one bent part, and the bent part is the edge part of the product to be formed.

[0035] Further, the second mold device 32 includes a second mold body 321 , and a second parting surface 322 is provided on a side opposite to the first mold device 31 .

[0036] When the first mold device 31 and the second mold device 32 are molded together for injection molding, a foil film gap for acco...

Embodiment 2

[0044] Please refer again figure 1 , image 3 and Figure 5 , in the embodiment of the present invention, the in-mold transfer printing system further includes a foil feeding mechanism 10, a foil feeding roller 11, a foil receiving mechanism 20 and a foil receiving roller 21, the foil feeding mechanism 10, the foil feeding roller 11, and the foil receiving mechanism 20 and the foil receiving roller 21 form a foil film transmission path, the foil film transmission path runs through the foil film gap between the first mold device 31 and the second mold device 32, and the foil film with the transfer pattern is transported to the In the injection molding mechanism 30 , after the transfer pattern is transferred to the product, it will continue to be conveyed through the foil film transmission path to the foil receiving mechanism 20 .

[0045] Further, the input end of the foil feeding roller 11 on the foil transmission path is provided with a tensioning mechanism 50 for realizing...

Abstract

The invention discloses an in-mold transfer printing system. The injection molding mechanism includes a first mold device and a second mold device oppositely arranged; a first parting surface is provided on the side of the first mold device opposite to the second mold device , which has at least one bending portion; the second mold device is provided with a second parting surface on the side opposite to the first mold device; the bending part of the first parting surface is provided with a deformable soft surface; the first mold device It includes a first driving device, the first driving device is drivingly connected with a transmission part, a pressing block is arranged at the front end of the transmission part, and the pressing block is aligned with the deformable soft surface. In the in-mold transfer printing system provided by the present invention, the pressing block is driven by the driving device to press the foil film on the product to be formed, so that the foil film can be closely attached to the product and prevent the foil film from forming a foil at the bend. The membrane drum edge ensures the smooth surface of the product after molding, ensures the quality of the finished product, and reduces the defective rate of the product to a certain extent.

Description

technical field [0001] The invention relates to the technical field of in-mold forming, in particular to an in-mold transfer printing system. Background technique [0002] IMR (In-Mold Decoration by Roller) is a processing technology for large-scale manufacturing of plastic parts exterior decoration, also known as in-mold transfer printing, which belongs to IMD (In-Mold Decoration) in-mold decoration technology. The basic principle of the in-mold transfer printing process is: print the pattern on the foil film, send the foil film into the mold cavity through the in-mold transfer printing equipment for injection molding, and the ink layer with the pattern on the foil film is separated from the foil film after injection molding Transfer printing to plastic parts to obtain plastic parts with decorative patterns on the surface. [0003] The advantage of in-mold transfer printing is that the produced plastic parts have a beautiful appearance and can transfer more complex pattern...
