Embodiment 2

[0051] Embodiment two: if Figure 4 As shown, in this embodiment, the third groove 122 is provided with a second soft rubber layer 124, and the second soft rubber layer 124 is respectively connected to the connecting bending portion 12 and the hard rubber of two adjacent curtain units. 2. The second soft rubber layer 124 increases the connection strength of the connecting bent parts 12 of two adjacent curtain units, so that the connecting bent parts 12 of two adjacent curtain units can be firmly connected together, so that The adhesive film 1 is not easy to bend and break during being pulled, so that the adhesive film 1 can work normally.

Embodiment 3

[0052] Embodiment three: as Figure 5 As shown, in this embodiment, a fourth groove 125 is laser engraved on the connecting bending portion 12 of two adjacent curtain units, and the second soft rubber layer 124 is respectively connected to two adjacent curtain strips. The connection bending part 12 of the unit and the hard glue 2, at the same time, part of the second soft glue layer 124 protrudes into the fourth groove 125, and the second soft glue layer 124 increases the connection and bending of two adjacent curtain units The connection strength of the part 12 allows the connecting and bending parts 12 of two adjacent curtain units to be firmly connected together, so that the adhesive film 1 is not easy to bend and break during the pulling process, ensuring that the adhesive film 1 can be normal Work.

Embodiment 4

[0053] Embodiment four: as Figure 6 As shown, in this embodiment, the second groove 121 is provided with a first soft rubber layer 123, and the first soft rubber layer 123 is respectively connected to the connecting bending portions 12 of two adjacent curtain strip units. The third groove 122 is provided with a second soft rubber layer 124, and the second soft rubber layer 124 is respectively connected to the connecting bending portion 12 and the hard rubber 2 of two adjacent curtain units. The first soft rubber layer 123 and the second soft rubber layer 124 increase the connection strength of the connection bending part 12 of two adjacent curtain strip units, so that the connection bending part 12 of two adjacent curtain strip units can be tightened. are firmly connected together, so that the adhesive film 1 is not easy to bend and break during being pulled, and ensures that the adhesive film 1 can work normally.

Abstract

The invention relates to the technical field of manufacturing processes of automobile rolling doors, in particular to a manufacturing process of an IMD type automobile rolling door. The process comprises the following steps of: 1. heating a glue film to soften the glue film; 2. carrying out plastic-suction forming treatment on the softened glue film by a plastic-suction forming method; 3. cuttingthe glue film into a preset shape after plastic-suction forming; 4. placing the glue film obtained in the step 3 into an injection mold; 5. closing the mold by an injection molding machine and injecting the molten hard glue into an injection mold, wherein the glue film and the hard glue are molded into a whole; and 6. and opening the mold of the injection molding machine and taking out the injection molded product. The manufacturing process of the IMD type automobile rolling door, provided by the application, replaces the flexible glue with the IMD glue film, and the pattern layer of the IMD glue film can be subjected to treatments such as pattern biting, pattern increasing, grain manufacturing and the like, and diversification of the IMD glue film is increased. The protective film layer of IMD glue film can prevent the pattern layer from being scraped flower, and makes IMD glue film's surface reach highlight effect simultaneously. The base layer of IMD glue film and hard glue are firmand the IMD glue film is difficult to take off from the hard glue.

Description

technical field [0001] The invention relates to the technical field of automobile rolling door manufacturing technology, in particular to an IMD type automobile rolling door manufacturing technology. Background technique [0002] The traditional automobile shutter door is made of hard rubber and soft rubber injection molding. The specific manufacturing process is: first injection molding the hard rubber, then embedding the hard rubber into the injection mold, closing the injection molding machine and injecting the soft rubber into the injection mold , soft rubber and hard rubber are injected into one body, and finally the injection molding machine opens the mold and takes out the injection molded product. Since the surface of soft rubber (TPE, a thermoplastic elastomer material) is relatively smooth, it is difficult to scratch, add patterns and create textures on the surface of soft rubber. The glue comes off. Contents of the invention [0003] The technical problem to b...
