Embodiment 1
[0026] Embodiment 1: as Figure 1 to Figure 3 As shown, the technical scheme adopted by the present invention is as follows: a welding process for plastic products, comprising the following steps:
[0027] S1. Place the base 2 on the first mold 3 and clamp it tightly;
[0028] S2. Embedding the top cover 1 on the second mold 6, so that the base 2 and the top cover 1 are arranged opposite to each other;
[0029] S3. Turn on the hydraulic drive system to make the second mold 6 drive the top cover 1 to move towards the base 2, and press it into the base 2;
[0030] S4. Turn on the motor to make the second mold 6 drive the top cover 1 to rotate relative to the base, so that the top cover 1 and the base 1 are welded and fixed.
[0031] The base 2 in step S1 includes a supporting base 23, a base body 24, a first welding ring surface 21 and a first rib 22, wherein the supporting base 23 is a plate-like structure, and the base body 24 is fixedly arranged on the supporting ba...
Embodiment 2
[0037] Embodiment 2: as Figure 4 to Figure 6 As shown, it is the second embodiment of the present invention. The difference between this embodiment and Embodiment 1 is that first ribs are arranged at intervals on the first welding ring surface and the second welding ring surface of Embodiment 1 respectively. 22 and the second rib 13, the first rib 22 and the second rib 13 are strip-shaped structures, and their material is consistent with the material of the top cover and the base, and is integrally injection molded with the top cover and the base, the first rib 22 and the second ribs 13 are arranged at even intervals along the periphery of the first welding ring surface and the second welding ring surface respectively. When welding, the top cover is pressed into the base, and the first ribs and the second ribs are alternately arranged. Two adjacent first ribs 22 and second ribs 13 are engaged with each other. When the motor drives the top cover to rotate, the first ribs 22 an...
