As shown in fig. 1 to 5, the present invention discloses an automotive interior cladding process, which is characterized in that the automotive interior cladding process adopts a mold 10 integrating injection molding and cladding, and the automotive interior cladding process comprises the following steps:
S1performing injection molding in an injection mold cavity a of the mold 10 to form an injection molded part 20;
S2moving the injection molded part 20 to the coating cavity b of the mold 10;
S3and pressing the compound skin 30 coated with the glue into the coating die cavity b through the injection molding part 20, and activating the glue by the waste heat of the injection molding part 20 so that the compound skin 30 is coated on the injection molding part 20. Here, the glue is preferably a hot melt, such as a PUR (polyurethane) hot melt, an aqueous glue, a PONR (non-reactive hot melt) hot melt, or the like.
Preferably, the mold 10 includes a male mold 11 and a female mold 12 which are vertically matched, at least two male mold portions 111 are arranged on the male mold 11, at least one injection female mold 121 and at least one over-mold 122 are arranged on the female mold 12, the male mold portions 111 and the injection female mold 121 are vertically matched to form an injection mold cavity a, and the male mold portions 111 and the over-mold 122 are vertically matched to form an over-mold cavity b.
The injection mold cavity a is used for injection molding, and the cladding mold cavity b is used for cladding. The injection molding and the laminating process can be completely completed on an injection molding machine through the mold 10.
According to an embodiment of the invention, said step S1The method specifically comprises the following steps: the male mold 11 and the female mold 12 are closed and injected into the injection mold cavity a, and the injection molded article 20 is formed on the corresponding male mold portion 111.
Here, the injection molded article 20 may be an interior part such as a frame part of an automobile.
Preferably, the step S2The method specifically comprises the following steps:
S21opening the mold after the injection molding is finished, so that the male mold 11 is separated from the female mold 12;
S22and rotating the female die 12 by 180 degrees so that the overlying female die 122 corresponds to the injection molded part 20 up and down.
Preferably, said step S3The method specifically comprises the following steps:
S31placing the laminating skin 30 coated with glue on the laminating concave die 122;
S32the male mold 11 and the female mold 12 are closed, and the injection molding member 20 presses the cover skin 30 into the cover cavity b.
In particular, in the operation of the above step S32At the same time, the injection mold cavity a formed between the other male mold portion 111 and the injection female mold 121 is injected, and the other injection molded article 20 is formed. This process remains for about a decade or so, for example, 10 seconds, until the surface temperature of the injection molded part 20 rises to 180 ℃ to 220 ℃.
Of course, different injection-molded materials will have different temperatures, and for example polypropylene (PP), Polycarbonate (PC) or ABS plastics are generally used.
Preferably, the step S32The residual heat temperature of the injection molded part 20 is preferably 80 to 140 ℃.
Different glue water needs to use different activation temperatures, for example, the activation temperature of PUR (polyurethane) hot melt adhesive is 60 ℃ to 70 ℃, the activation temperature of water-based glue is about 60 ℃, and the activation temperature of PONR hot melt adhesive is about 140 ℃ (for example, infrared heating can be used).
Because the mold 10 integrates the injection molding and coating processes, the injection molded part 20 does not need to be taken out after injection molding, the surface temperature of the injection molded part is high enough, the next coating process can be directly carried out, and the activation of the glue can be realized by transferring the surface heat of the injection molded part 20 to the coating surface 30, so that the process of heating and activating the glue by hot water in the traditional process is omitted, and the step of cooling the injection molded part 20 firstly to take out the injection molded part 20 is also omitted.
Further, in the step S3The method also comprises the following steps:
S4after the injection molded part 20 and the skin 30 are completely coated, the injection molded part 20 is cooled by injecting cooling liquid into the male mold 11 and the female mold 12 in a state that the male mold 11 and the female mold 12 are closed.
The composite skin 30 may preferably be a material such as PVC (polyvinyl chloride), TPO (thermoplastic polyolefin elastomer), PU (polyurethane material), or leather, and these materials or other materials that can be used as a skin may be used.
In addition, the step S4The method also comprises the following steps:
S5taking out the injection molded part 20;
S6and returning to the step S2The next injection molded part 20 is coated.
Here, the cover skin 30 coated with the glue may be put in by a robot, the glue is activated by using a surface temperature of the injection molded article 20, the male mold 11 and the female mold 12 are closed, and a cooling liquid, which may be cooling water or the like, is injected into the male mold 11 and the female mold 12 to cool the injection molded article 20.
The injection molded part 20 is then ejected from the male mold 11.
In summary, the automobile interior coating process of the present invention has the following advantages:
firstly, a laminating die for cladding is omitted;
secondly, the injection molding part does not need to be taken down, the glue can be activated by utilizing the waste heat of the injection molding part, and an additional glue activating device is omitted;
thirdly, the processes of injection molding part transportation, injection molding part inventory, injection molding part logistics, no WC (wolfram carbide) and the like are omitted;
and fourthly, the automation degree of the coating part process is improved, so that the product production is more efficient.
