Achieving the above object The technical scheme of the utility model is that the scooter pedal mold has a bridge structure, including a punch, a die and a welding chamber, the punch is arranged on the top of the die, and the top of the punch is arranged along the top of the die. There is a pair of split inlet holes symmetrically on the center line, a bridge position is provided between the split inlet holes, a process hole is opened on the top of the punch, and a welding chamber is provided at the bottom of the pair of split inlet holes , the inside of the punch is provided with a back empty cutter milling groove, the inside of the die is provided with a concave mold cavity, and the concave mold cavity is provided with a punch core.

A lifting hole is opened on one side surface of the male mold, and a positioning pin is arranged on one side surface of the concave mold.

The bottom of the die is provided with a plurality of assembly holes and a plurality of positioning holes, both of which are two in number.

The height of the concave mold table is 6 mm.

The average sinking of the bridge position is 15mm.

The bottom of the die is provided with a feed port.

The one-shaped bridge structure of the scooter pedal mold made by the technical scheme of the utility model adopts the design of two diversion holes, so that the aluminum rods evenly flow into the two diversion holes of the diversion combination mold, which solves the problem of the anode on the surface of the scooter pedal. The problem of welding traces after oxidation treatment reduces the process, saves working time and improves work efficiency.
