[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0019] In positive mold adsorption molding, the skin is adsorbed onto the skeleton surface by vacuum adsorption. The resulting skeleton product has uneven edges and thick edges.

[0020] Reference Figure 1 and Figure 2In some embodiments of the present invention, a positive mold for adsorbing and forming a thick-edged surface is used to adsorb and form the skin onto the surface of the skeleton. The positive mold 5 has a punch 51, and the skeleton 1 is fitted onto the punch 51. A pad 3 for supporting the skin 2 is provided on the positive mold 5 outside the punch. The skin 2 is laid on the skeleton 1, and the pad supports the skin on the outer side of the outer edge of the skeleton 1, ensuring that the height of the skin between the skeleton and the pad is higher than the height of the skin at the outer edge of the skeleton. A clamping frame for fixing the outer edge of the skin is provided outside the pad.

[0021] By placing pads on the outside of the skeleton to support the skin located on the outer edge of the skeleton, during adsorption molding, the adsorption force causes the skin to be covered to the outer edge of the skeleton. Since the height of the skin on the outer edge of the skeleton is greater than that of the skin at the outer edge of the skeleton, when the skin is subjected to a downward adsorption force, the skin deforms around the skeleton contour, so that the skin and the skeleton contour can make full contact, making the edge of the skeleton smooth and preventing the appearance of thick edges.

[0022] like Figure 2 The pad block 3 is set on the male mold 5 and is vertically positioned on the male mold 5. The side of the pad block 3 near the skeleton is set as an inclined surface, and the other side of the pad block 3 is set as a vertical surface. The top of the pad block 5 is set as an arc transition structure to reduce the obstruction to the deformation of the skin.

[0023] like Figure 3 As shown, the horizontal distance w between the support position of the pad 3 on the skin 2 and the edge of the skeleton 1 is not less than 20mm, forming a gap between the two, providing sufficient space for the skin to be adsorbed and deformed at the edge of the skeleton.

[0024] The height difference H2 between the support position of the pad block 3 on the skin 2 and the edge position of the skeleton 1 is greater than 15mm. The height difference H1 between the pad block's position on the male mold and the skeleton is less than 30mm.

[0025] like Figure 3 The height of the clamping frame holding the skin should be lower than the height of the pad, so that the skin located at the outer edge of the skeleton is subjected to an upward tension.

[0026] Multiple adjusting shims 4 are set between the pad block 3 and the male mold 5 to adjust the height difference between the skin at the support position and the skin at the outer edge of the skeleton.

[0027] In some embodiments, the pad block 3 and the male mold 5 are integrally formed.

[0028] In some embodiments, such as Figure 1 and 2As shown, two punches 51 are symmetrically arranged on the male mold. The pads 3 are arranged on one side of the punches 51 along the length direction and are located near the two sides of the male mold. The clamping frame clamps and fixes the skin edge around the male mold.

[0029] like Figure 2 A raised strip is provided between the two punches to support the skin located in the middle, and grooves are formed around the punches to allow the skin to deform.

[0030] During adsorption molding, the skeleton is placed on two punches, the skin is set on the surface of the skeleton, and the skin is supported on both sides by strip-shaped pads. The skin is clamped and fixed at the edge by the upper and lower clamping frames of the clamping frame. The skin is adsorbed and molded onto the surface of the skeleton by vacuum adsorption.

[0031] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in during use. They are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Furthermore, the use of terms such as "horizontal" and "vertical" in the description of this invention does not imply that the components are required to be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0033] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
