Description

Technical Field

[0001] This utility model relates to the field of automotive interior manufacturing technology, and in particular to an activation tooling for covering the side of automotive interior skin with contoured pressing blocks. Background Technology

[0002] With the improvement of people's living standards and the rapid development of the automotive industry, the requirements for automotive interiors are also gradually increasing. Using the IMG-SP process, automotive interior skin coverings offer advantages such as a soft touch and diverse colors and textures, leading to their increasing popularity. The process involves adsorption molding, sewing, pre-application, activation, and bonding. The purpose of activation is to ensure the adhesive firmly bonds the skin to the substrate (skeleton) to meet tear resistance requirements. This process involves activating the adhesive between the skin and substrate using infrared lamps. The activation tooling uses a silicone film to create a vacuum seal around the skin and substrate, then creates a vacuum, causing the silicone film to gradually shrink. This applies pressure to the surfaces of the skin and substrate, and vacuum heating is applied, ultimately bonding the skin to the substrate. However, in the IMG-SP process, due to the different contact sequence and force of the product with the silicone film, the upper part of the car's rounded corners comes into contact with the silicone film first, with a large force, while the sides come into contact with the silicone film later, with a small force. In addition, the silicone film is highly elastic, which makes it very easy for the sides and rounded corners to collapse and wrinkle. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an activation tooling with contoured pressing blocks on the side of automotive interior leather covering, thereby solving the above-mentioned technical problems.

[0004] The technical solution adopted in this utility model is as follows:

[0005] An activation tooling for covering the side of an automotive interior trim panel with a contoured pressing block includes a base plate, a fixture, and a contoured pressing block. The fixture is fixed to the base plate, and the base plate is also provided with a mounting post. The contoured pressing block is fixed together with a connecting arm, and the connecting arm is hinged to the mounting post via a pin. The contoured pressing block is located on the side of the fixture.

[0006] The aforementioned activation tooling for covering the side of automotive interior leather with a contoured pressing block is characterized in that the contoured pressing block is in an open state, which is turned out of the fixture, or in a closed state, which is closed on the side of the fixture.

[0007] This utility model is an activation tooling with contoured pressing blocks on the side for covering automotive interior skin. It is scientifically designed, rationally structured, simple in mechanism, easy to operate, safe and reliable in function, and has an ideal effect, thus ensuring the excellent quality of automotive interior skin covering products.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described below are merely illustrative of this utility model. Key terms that need attention in these descriptions, including "contour-forming pressure block," "installation pile," "open state," and "closed state," are only for the purpose of facilitating and simplifying the description of this utility model, and therefore should not be construed as limiting this utility model.

[0017] like Figures 1-4 As shown, this utility model relates to an activation tooling for automotive interior leather covering with a contoured pressing block 3. During production, the contoured pressing block 3 is pressed onto the side and rounded corners of the product where collapse or wrinkles are likely to occur. The tooling includes a base plate 1, a fixture 2, and a contoured pressing block 3. The fixture 2 is fixed to the base plate 1, and the base plate 1 is also provided with a mounting post 4. The contoured pressing block 3 is fixed together with a connecting arm 6. The connecting arm 6 is hinged to the mounting post 4 via a pin 5. The contoured pressing block 3 is located on the side of the fixture 2, where the leather covering is prone to collapse or wrinkles during production. Figure 1 and Figure 2As shown, the far-reaching contouring block 3 is the open contouring block 3a, which is flipped open outside the tire 2, while the close-up contouring block 3 is the closed contouring block 3b, which is closed on the side of the tire 2.

[0018] Using the IMG-SP process, and employing the activation tooling with contoured pressing blocks on the sides of the automotive interior trim covering, the production process is as follows:

[0019] 1. Lay the glue-coated skin P onto the skeleton G to form a pre-wrapped semi-finished product;

[0020] 2. See Figure 5 As shown, open the contour pressing block 3 to allow the pre-packaged semi-finished products to be placed;

[0021] 3. For example Figure 2 As shown, the pre-packaged semi-finished product is placed on the fixture 2 of the tooling;

[0022] 4. See Figure 6 As shown, flip the contoured pressure block 3, which opens on the side of the tooling, into place and cover the pre-wrapped side of the semi-finished product on the jig 2.

[0023] 5. Exit the safety light curtain and press the activation start button;

[0024] 6. Lower the silicone film to cover the entire pre-packaged semi-finished product and the conformal pressing block 3, forming a circumferential seal;

[0025] 7. Infrared lamp heating, heating for the set time;

[0026] 8. Vacuum the bottom to shrink the silicone film and press it firmly onto the surface of the pre-packaged semi-finished product;

[0027] 9. Vacuum heating is applied to activate the adhesive and bond the skin P to the skeleton G.

[0028] 10. After the vacuum heating time is reached, turn on the air cooler to blow cold air;

[0029] 11. Open the silicone film, open the contouring block 3, and take out the product.

[0030] Because the rigid contouring block 3 is suitable for the product shape during the above process, it can be tightly pressed onto the sides and rounded corners where collapse and wrinkles are prone to occur, thus preventing the surface P from collapsing and wrinkling.

[0031] The above description is only a general embodiment of this utility model. For those skilled in the art, there are various other embodiments with modifications and variations, which will not be elaborated here. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model are included within the protection scope claimed by this utility model.
