Description

Skin Thermocompression Mold Device of Interior Materials of Automobile}

The present invention relates to a skin thermal compression device for automobile interior materials. More specifically, before thermal compression of the skin to the interior material using the upper and lower molds, a heating box is inserted between the upper and lower molds to preheat the skin to a certain temperature. It relates to a mold device for thermal compression of skins for automobile interior materials, which then heat-compresses the skins to the interior materials.

In general, interior materials for automobiles include instrument panels, door trims, pillars, trunk mats, package trims, headliners, etc., and the materials and composition of these interior materials vary depending on the vehicle type.

In addition, some vehicle models use interior materials that are injection molded with only a hard substrate, while some other vehicle models use interior materials that have a soft skin material attached to part or the entire surface of the injection molded hard substrate.

In addition, the materials of the hard substrate that are injection molded include PP, PP felt, PP board (POLY-PROPYLENE BOARD), ABS, WOOD STOCK, and resin felt ( RESIN FELT) is mainly used, and the soft skin material bonded to the surface of the substrate is PE FOAM, PP FOAM, or PE foam on the back of the skin paper made of non-woven fabric, fabric, or PVC. Those with PU FOAM etc. attached are mainly used.

In addition, for injection molding of the automobile interior base material and attachment of the skin material, low-pressure injection molding method and high-pressure injection molding method are mainly used in the related art. In the low-pressure injection molding method, the skin material is formed before injecting the injection liquid of the base material. This is a method in which substrate molding and skin material adhesion are carried out simultaneously by injecting injection liquid at low pressure in a pre-injected state between both molds. Workability and productivity can be said to be good because substrate molding and skin material adhesion are performed simultaneously, but this low pressure Injection equipment is expensive, costing 2 to 3 billion won, so there are many factors that increase the cost, and the damage to the skin material is severe, leading to poor quality.

An example of prior art to solve the above problems is the Republic of Korea Intellectual Property Office Patent Publication No. 10-2004-0061085 (name: Molding method and molding apparatus for interior materials for automobiles).

The prior art molds the substrate by injecting the injection liquid at high pressure into the molding surfaces of the upper and lower molds to which the primary press pressure is applied, followed by cooling and aging, and releasing the primary press pressure. In the process, after the above step of separating the upper and lower molds, a heating device is introduced to heat and melt the surface of the substrate, and a subsidy mold whose bottom part is the same shape as the upper mold molding surface and a skin material are introduced, and then the subsidy mold is placed on the molding surface of the upper mold. 2. A step of setting the sub-type integrally with a second press of the upper mold on which the sub-type is set integrally to adhere the skin material to the surface of the substrate, and cooling the bonded substrate and skin material to maintain the adhesive state. The main point is to include a secondary cooling step and a step of removing the substrate with the skin material attached from the lower mold and the original position of the subsidy mold separated from the upper mold after releasing the secondary press pressure of the upper and lower molds.

However, although the above prior art may be able to automate the process of adhering the skin material to the surface of the substrate, the work does not end with adhering the skin material to the surface of the substrate, but rather wraps the end of the skin material along the outline of the substrate and then , the process of re-adhering the wrapped area must be carried out to manufacture the interior material of the finished product. However, in the prior art, a process of automatically wrapping and adhering the end of the mentioned skin material to the outer edge of the base material and a device for implementing this are provided. The disadvantage is that the interior materials of the finished product cannot be molded.

In addition, the adhesive applied to the interior material must be heated to a predetermined temperature to activate the adhesive performance, and the skin pressed to the interior material must also be heated to a predetermined temperature to soften the skin and improve the adhesive performance when pressed. In the prior art, the skin or interior material is used to activate the adhesive performance. Since there is no means to preheat the skin or to apply heat to a predetermined temperature during compression, the adhesiveness of the skin is reduced and product defects frequently occur.
