[0003] (1) Deformation in the direction of welding pressure: The injection molded part may further deform in a specific direction under welding pressure, which is usually related to the flow direction of the material and the shrinkage during cooling;

[0004] (2) Uneven softening of weld ribs: Due to product deformation or inaccurate positioning, weld ribs (reinforcement ribs used to enhance welding strength) may not contact the hot plate evenly, resulting in inconsistent softening and affecting welding quality;

[0005] (3) Poor welding dimensions: Uneven softening and deformation may cause the dimensions of the final product to not meet the design requirements, affecting assembly performance and appearance. Utility Model Content

[0022] Several groups of contour-profiling moving components are installed at the bottom of the lifting plate 1. The contour-profiling moving components include a guide rail 2 and a parallel cylinder 3. The guide rail 2 is fixed to the bottom of the lifting plate 1 through a first fixed plate 4. A slider 5 is provided on the guide rail 2. The slider 5 can slide along the guide rail 2. A workpiece sliding plate 6 is installed on the slider 5. The parallel cylinder 3 is fixed to the bottom of the lifting plate 1 through a second fixed plate 7. The push rod end of the parallel cylinder 3 is connected to the workpiece sliding plate 6. A contour-profiling workpiece 8 is provided on the workpiece sliding plate 6.

[0023] The mold top plate A of this embodiment is used to install the upper cold mold D, the lifting plate 1 and the lifting drive mechanism of the mold. The welding product C is placed on the upper cold mold D of the mold. The parallel cylinder 3 pushes the workpiece sliding plate 6 to push the contoured workpiece 8 around the welding product C. Then the lifting drive mechanism drives the lifting plate 1 to rise, thereby driving the contoured workpiece 8 to rise and pull the welding product C around to achieve the purpose of shaping the welding product C.

[0024] In order to realize the operation of the lifting drive mechanism driving the lifting plate 1 to rise, a plurality of guide pillars 9 are fixed at the bottom of the mold top plate A, and a plurality of linear bearings 10 are arranged on the lifting plate 1. The guide pillars 9 and the linear bearings 10 are arranged one by one. The guide pillars 9 are passed through the corresponding linear bearings 10. The lifting plate 1 can realize low-friction lifting and sliding through the cooperation of the guide pillars 9 and the linear bearings 10.

[0025] The lifting drive mechanism includes a lifting cylinder 11 and a pin seat 12. The pin seat 12 is fixed at the bottom of the mold top plate A. An inclined surface structure 13 is arranged in the pin seat 12. The lifting cylinder 11 is installed on the upper surface of the lifting plate 1 through a third fixed plate 14. A latch 15 is installed at the end of the push rod of the lifting cylinder 11. The latch 15 is a wedge-shaped block structure. The latch 15 cooperates with the inclined surface structure 13 in the pin seat 12.

[0026] The push rod end of the lifting cylinder 11 extends out to push the pin 15 into the pin seat 12. The pin 15 is a wedge-shaped block structure, and the pin 15 cooperates with the inclined structure 13. Finally, the pin 15 moves upward, and the pin 15 drives the lifting cylinder 11 and the lifting plate 1 to rise to complete the lifting action. In addition, in order to reduce the friction between the inclined structure 13 and the pin 15, a slide plate 16 can be set on the inclined structure 13 in the pin seat 12. The slide plate 16 is made of a material with a low friction coefficient, which can greatly reduce the contact friction.
