[0022] Please refer to Figures 1-4 , a processing fixture for an automotive variable intake manifold of the present utility model, which includes a processing table 1. A bottom mold 2 is provided at the upper end of the processing table 1. A first telescopic cylinder 4 is provided above the bottom mold 2. A top mold 3 is provided at the output end of the first telescopic cylinder 4. Two cavities are symmetrically arranged in the bottom mold 2. A negative pressure fan 6 is fixedly provided at the upper end of the processing table 1. The air suction end of the negative pressure fan 6 is communicated with one end of the cavity through a first conduit 5. Two support rods 9 are symmetrically arranged on the upper end of the processing table 1 with respect to the bottom mold 2. A positioning shaft 8 is rotatably provided at the top of the support rod 9. A driven block 12 is provided at one end of the positioning shaft 8 away from the support rod 9.
