[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] To further understand the content of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings.

[0026] Combined with Figure 1 , a processing mold for an automotive rubber sealing ring of the present utility model includes a fixed outer frame 1. A split lower mold 2 for vibrating blanking is sleeved on the fixed outer frame 1. An upper pressing mold 3 for pressing the film is arranged at the upper end of the split lower mold 2. The fixed outer frame 1 includes a bottom plate 11. Side columns 12 are arranged on both sides of the bottom plate 11. A lifting spring 121 is sleeved on the side columns 12. The upper end of the side column 12 is fitted with a lower mold frame 21. The split lower mold 2 includes a lower mold frame 21 sleeved on the side column 12, a lower positioning column 22 fixedly arranged at the lower end of the lower mold frame 21. A split mold 212 is movably arranged in the lower mold frame 21. A vibrator 213 is arranged at the lower end of the split mold 212. The side column 12 passes through and sleeves the lower mold frame 21 and the pressing mold 33 which are arranged corresponding to each other up and down.

[0027] Specifically, the bottom plate 11 and the side columns 12 play a fixing role. The lifting spring 121 provides an elastic supporting force for the lower mold frame 21. The pressing mold 33 can be pressed down to coincide with the lower mold frame 21 correspondingly. The split mold 212 and the lower mold frame 21 are of a split type. The vibration of the vibrator 213 at the lower end of the split mold 212 can drive the sealing ring to vibrate to realize blanking. The working process of this automotive rubber ring is as follows: the pressing mold 33 is pressed down and the lower mold frame 21 descends together until the lower mold frame 21 is completely attached to the bottom plate 11. At this time, the inside of the pressing mold 33 and the lower mold frame 21 is filled with material to form a rubber ring. Until it is formed, the pressing mold 33 rises. At the same time, the lower mold frame 21 rebounds under the elastic action of the lifting spring 121. The vibration of the vibrator 213 drives the split mold 212 to vibrate to help the rubber ring blanking, realizing the processing of the rubber ring. This mold can slide up along the side column 12 for disassembly and assembly. At the same time, the mold clamping is a pressing control of the air cylinder, and the extrusion force between the upper and lower molds is relatively strong and stable.

[0028] The present utility model will be further described below with reference to the embodiments.

[0029] Embodiment 1:

[0030] Combined with Figures 2 - 6 , the fixed outer frame 1 further includes an upper plate 13 inserted into the side column 12.
