As shown in fig. 10 to 16, the lower mold mounting apparatus 300 is used to mount a lower mold 400, and includes a main support mold 301, a main driving mechanism 302, a side mold 303, a side driving mechanism 304, a clamping mechanism 305, and a recessed hemming portion (not shown in the drawings).

The main supporting mold 301 is matched with the lower mold 400 in shape to fix the lower mold 400. The lower mold 400 has a plurality of alignment pins 401, and the alignment pins 401 are shaped to match the positions of the alignment holes on the skin.

The main drive mechanism 302 includes a support plate 321, a driver 322, a lead screw 323, a pressure sensor 324, a guide cylinder 325, and a guide shaft 326.

The driver 322 is a servo motor, and is fixed on the frame 101 and located below the center of the support plate 321, the output end of the motor is fixedly connected with the screw rod 323, and the top end of the screw rod 323 is provided with the pressure sensor 324. Under the control of the control mechanism, the driver 322 drives the screw rod 323 to ascend or descend, and drives the pressure sensor 324, the support plate 321, the main support mold 301, the side mold 303 and the clamping mechanism 305 to ascend and descend together.

The support plate 321 is placed on the pressure sensor 324, and the main support mold 301, the side mold 303, the side drive mechanism 304, and the clamp mechanism 305 are mounted on the upper surface.

After the lower die 400 is provided with the main supporting die tire 301, the skin is placed on the lower die 400, the positioning pins 401 are driven by the air cylinders fixed with the positioning pins to extend into the positioning holes, and the skin is spread on the lower die 400. The clamping mechanism 305 operates to clamp the reserved edge.

When the driver 322 drives the supporting plate 321 to ascend, the main supporting mold 301, the side mold 303, the lower mold 400 and the surface skin ascend together until the surface skin contacts the upper mold in an overturned state, and the surface skin is attached to the vehicle interior framework to obtain a product to be edge-wrapped. The positioning pins 401 retract, so that the edge of the edge mold 303 is convenient to be covered. In the process of attaching the skin to the vehicle interior skeleton to obtain a product to be covered, the pressure change in the whole process can be known through the pressure change of the pressure sensor 324, so that the force of attaching the skin to the vehicle interior skeleton is controlled.

When the edge is initially clamped, the gap between the pneumatic clamp 352 and the edge mold tire 303 is smaller than the thickness of the reserved edge, when the main driving mechanism 302 stops rising, the edge mold tire 303 and the pneumatic clamp 352 continue rising, but the pneumatic clamp 352 slowly turns outwards under the driving of the turning cylinder 351, so that the gap between the pneumatic clamp 352 and the edge mold tire 303 is gradually increased in the rising process, and when the reserved edge is attached to a product to be covered with the edge, the width of the gap is larger than the thickness of the reserved edge. The whole process simulates manual edge covering.

After the surrounding edge covering is finished, the driver 322 drives the supporting plate 321 to descend by a certain height, so as to drive the main supporting mold 301, the side mold 303 and the overturning cylinder 351 to descend synchronously, and at the moment, the sunken edge covering part arranged on the fixed frame 121 starts to act. The sunken bordure portion is including sunken bordure cylinder and fixing the sunken bordure piece at its output. The concave edge wrapping piece is positioned below the concave part, the shape of the concave edge wrapping piece is matched with that of the concave part, and the concave part is embedded into the concave part to rise upwards under the driving of the concave cylinder, so that the reserved edge at the position is attached to the periphery of the cavity of the concave part in an extruding mode. And then the concave edge covering piece exits from the concave part, and all edge covering is finished to obtain the product with the finished edge covering.

The method of use of the baking welt composite apparatus 1000 is as follows:

first, the fixing frame 121 of the upper die turnover device 100 is turned over to a certain angle, an operator mounts the car interior framework on the fixing frame 121, then the fixing frame 121 is turned over to return to an unturned state, and the four clamping cylinders further fix the car interior framework. And fixing the lower die 400 and the surface skin, lifting the lower die and the surface skin, returning the four clamping cylinders to the original positions, and attaching the surface skin to the surface of the automotive interior framework to obtain a product to be wrapped. Then the four clamping cylinders act to clamp the product to be edge-wrapped, and at the moment, the baking mechanism descends to begin baking the product to be edge-wrapped. And after baking, the baking mechanism returns. The side mold 303 continues to rise to wrap the reserved sides around the product to be wrapped. The side mold 303 descends and the recessed hemming portion starts to move to hem the reserved hem of the recessed portion. All the mechanisms return to the original positions, the fixed frame 121 is turned outwards, and an operator takes down the product to finish the process.
