[0045] like Figure 2 and Figure 3As shown, the first part to be welded 2 and the second part to be welded 3 may both be plastic parts. The first part to be welded 2 may be provided with a first welding portion 4, which is used to be heated and melted. The second part to be welded 3 may be provided with a second welding portion 5, which is used to be heated and melted. After the first welding portion 4 and the second welding portion 5 are heated and melted, the first welding portion 4 is pressed against the second welding portion 5 and cooled and solidified, and a weld 9 is formed between the first welding portion 4 and the second welding portion 5, so that the first part to be welded 2 and the second part to be welded 3 are fixedly connected. The first part to be welded 2 may be clamped by a first profiling fixture 6, and the second part to be welded 3 may be clamped by a second profiling fixture 7, and the first profiling fixture 6 and / or the second profiling fixture 7 are loaded to press the first welding portion 4 and the second welding portion 5. In the illustrated embodiment, the first part to be welded 2 may be a lampshade of a vehicle lamp, and the second part to be welded 3 may be a lamp holder of a vehicle lamp. The first welding portion 4 may be a welding rib of the top plate and the bottom plate of the lampshade when the lamp is installed on the vehicle. The second welding portion 5 can be welding ribs of the top plate and the bottom plate of the lamp holder when the lamp is installed on the vehicle.

[0046] like Figures 1 to 3 As shown, the flattening die body 1 is provided with at least one contact portion 8, and the contact portion 8 presses and sticks to the weld 9 and the side wall adjacent to the weld 9, and the molten material overflowing from the weld 9 is flattened by the contact portion 8 and fits the side wall adjacent to the weld 9, so as to avoid the formation of irregular burrs after solidification, which damages the appearance and causes the contour size to be inaccurate. In the illustrated embodiment of the first welded part 2 welding the second welded part 3, after the first weld part 4 is pressed against the second weld part 5 for two seconds, the contact portion 8 presses and sticks to the weld 9 and the side walls of the first weld part 4 and the second weld part 5 on the upper and lower sides of the weld 9, and the molten material of the first weld part 4 and the second weld part 5 overflowing from the weld 9 is flattened by the contact portion 8 and fits the side walls of the first weld part 4 and the second weld part 5. There is a vertical gap between the first profiling fixture 6 and the second profiling fixture 7, and the contact portion 8 extends from the vertical gap in the horizontal direction to press and stick to the weld 9 and the side wall adjacent to the weld 9.

[0047] like Figure 1 As shown, the contact portion 8 may be provided with a contact wall 10 , which fits the weld seam 9 and the side wall adjacent to the weld seam 9 , so as to press and fit the weld seam 9 and the side wall adjacent to the weld seam 9 .

[0048] like Figure 1As shown, the hot melt welding weld overflow flattening die is provided with a loading mechanism 11, which drives the flattening die body 1 so that the contact portion 8 presses and sticks to the weld 9 and the side wall adjacent to the weld 9, and drives the flattening die body 1 to move so that the contact portion 8 sticks to the weld 9 and the side wall adjacent to the weld 9, and loads the flattening die body 1 so that the contact portion 8 presses against the weld 9 and the side wall adjacent to the weld 9. In addition, the loading mechanism 11 can also drive the flattening die body 1 to move so that the contact portion 8 leaves the weld 9 and the side wall adjacent to the weld 9. The loading mechanism 11 can be a cylinder that can be extended and retracted to drive the flattening die body 1 to approach and move away from the weld 9 and the side wall adjacent to the weld 9. In the illustrated embodiment of the first workpiece 2 to be welded to the second workpiece 3 to be welded, the loading mechanism 11 pushes and pulls horizontally so that the contact portion 8 enters and exits the vertical interval between the first profiling fixture 6 and the second profiling fixture 7 along the horizontal direction.

[0049] like Figure 1 and Figure 2 As shown, the hot melt welding weld overflow flattening die is also provided with a guide mechanism 12, which guides the flattening die body 1 so that the contact portion 8 presses and sticks to the weld 9 and the side wall adjacent to the weld 9, and guides the flattening die body 1 to move so that the contact portion 8 sticks to the weld 9 and the side wall adjacent to the weld 9, and guides the flattening die body 1 so that the contact portion 8 presses against the weld 9 and the side wall adjacent to the weld 9. In addition, the guide mechanism 12 can also guide the flattening die body 1 to move so that the contact portion 8 leaves the weld 9 and the side wall adjacent to the weld 9. The guide mechanism 12 can be a sliding guide mechanism, such as the slide rail slider mechanism shown in the figure. In the embodiment shown in the figure where the first workpiece 2 to be welded is welded to the second workpiece 3 to be welded, the guide mechanism 12 guides the flattening die body 1 to move in the lateral direction.

[0050] like Figure 1 As shown, the flattening die body 1 can be provided with a plurality of the aforementioned contact portions 8, and the plurality of contact portions 8 are arranged along the weld 9, and each contact portion 8 presses and sticks to a portion of the weld 9 and the side wall adjacent to the portion of the weld 9, so that all the overflow of the weld 9 is flattened by the plurality of contact portions 8. Compared with providing one contact portion 8, providing a plurality of contact portions 8 can reduce the size of each contact portion 8, making the size control of each contact portion 8 simpler, and facilitating the contact portion 8 to fit the weld 9 and the side wall adjacent to the weld 9. In the illustrated embodiment of the first workpiece 2 to be welded to the second workpiece 3 to be welded, each contact portion 8 presses and sticks to a section of the weld 9 and the side walls of the first welding portion 4 and the second welding portion 5 on the upper and lower sides of the section of the weld 9. Compared with providing a contact portion 8 extending along the narrow and long weld 9, providing a plurality of contact portions 8 can shorten the length of each contact portion 8. The plurality of contact portions 8 can be extended into an arc shape to match the arc-shaped weld 9.

[0051] like Figure 1As shown, the interval 13 between two adjacent contact portions 8 can be 0.1 to 0.5 mm. The small-sized interval 13 reduces the flash burrs of the weld 9 at the interval 13 and provides space for adjusting the position of the contact portion 8, as described later. In the embodiment of the first workpiece 2 to be welded to the second workpiece 3 to be welded, there is a longitudinal interval 13 between the two adjacent contact portions 8.

[0052] like Figures 1 to 3 As shown, the flattening die body 1 may be provided with a seat body 14, and the seat body 14 may be a seat plate. In the embodiment shown in the figure, the first workpiece 2 to be welded to the second workpiece 3 to be welded, the seat plate is horizontal. Among the aforementioned multiple contact portions 8, at least two adjacent contact portions 8 are fixed to the seat body 14, and these contact portions 8 are thus fixed as a whole, which is convenient for being synchronously driven, loaded and guided, as described later. In the embodiment shown in the figure, the first workpiece 2 to be welded to the second workpiece 3 to be welded, the six contact portions 8 arranged along the weld seam 9 are fixed to the seat body 14, and are synchronously loaded and guided in the transverse direction. Continue to refer to Figure 1 The second contact portion 20 having a different driving and loading direction from the contact portion 8 on the seat body 14 can be set independently of the seat body 14 to achieve different driving and loading directions.

[0053] like Figure 1 and Figure 2 As shown, the contact portion 8 can be fixed to the seat body 14 by the bracket 15 in an adjustable position, so as to facilitate the adjustment of the installation position of the contact portion 8 so that the contact portion 8 fits the weld 9 and the side wall adjacent to the weld 9. Each bracket 15 can be set to fix only one contact portion 8, and each contact portion 8 is independently fixed on its own bracket 15, so as to avoid the position adjustment of the contact portion 8 being restricted by other contact portions 8 on the same bracket 15. The bracket 15 can be provided with a waist-shaped hole 16 to be fixedly connected to the seat body 14, so that the bracket 15 can be fixed to the seat body 14 in an adjustable position, and the bracket 15 can be provided with a waist-shaped hole 16 to be fixedly connected to the contact portion 8, so that the contact portion 8 can be fixed to the bracket 15 in an adjustable position, and the contact portion 8 supported by the bracket 15 can be adjusted relative to the seat body 14. In the illustrated embodiment of welding the first workpiece 2 to be welded to the second workpiece 3 to be welded, the bottom plate of the bracket 15 is horizontal and supported on the base body 14, the bottom plate of the bracket 15 can be provided with a waist-shaped hole 16 and fixed to the base body 14 by bolts, the long axis of the waist-shaped hole 16 on the bottom plate of the bracket 15 can extend horizontally, the vertical plate of the bracket 15 extends vertically and can be provided with a waist-shaped hole 16 and fixed to the contact portion 8 by bolts, and the long axis of the waist-shaped hole 16 on the vertical plate of the bracket 15 can extend vertically.

[0054] like Figure 1As shown, the cylinder as the loading mechanism 11 can be arranged on the seat body 14, and the cylinder drives the seat body 14, thereby synchronously driving and loading the multiple contact parts 8 fixed to the seat body 14, so that the multiple contact parts 8 synchronously press and stick to the weld 9 and the side wall adjacent to the weld 9. The main body of the cylinder as the loading mechanism 11, such as a cylinder tube, can be fixed to the base 17, and the telescopic part of the cylinder, such as a piston rod, is connected to the seat body 14, and the seat body 14 is driven relative to the base 17.

[0055] like Figure 1 and Figure 2 As shown, the sliding guide mechanism as the guide mechanism 12 includes a sliding guide member 18, which can be arranged on the seat body 14, and guides the seat body 14 so as to synchronously guide the multiple contact portions 8 fixed to the seat body 14, so that the multiple contact portions 8 synchronously press and stick to the weld 9 and the side wall adjacent to the weld 9. The matching member 19 of the sliding guide member 18 can be fixed to the base 17, the sliding guide member 18 is connected to the seat body 14, and the seat body 14 is guided relative to the base 17. The sliding guide member 18 can be a slide rail, and the sliding guide matching member 19 can be a slider.

[0056] like Figure 1 and Figure 2 As shown, the seat body 14 can be configured with multiple sliding guides 18, and the multiple sliding guides 18 guide different positions of the seat body 14. Compared with using a single sliding guide 18 to guide a single position of the seat body 14, the deformation of the seat body 14 during loading is reduced, ensuring that the multiple contact portions 8 fit the weld 9 and the side walls adjacent to the weld 9.

[0057] exist Figure 2 and Figure 3 In the embodiment shown in which the first workpiece 2 to be welded is welded to the second workpiece 3 to be welded, the two aforementioned hot melt welding weld overflow flattening dies are respectively arranged on the lateral sides of two welds 9 in the lateral direction, and each of the aforementioned hot melt welding weld overflow flattening dies flattens one weld 9.
