Description

Technical Field

[0001] The utility model relates to the technical field of processing new energy vehicle charging piles, in particular to a protective shell mold for new energy vehicle charging piles. Background Art

[0002] A new energy vehicle charging pile refers to a charging device that provides energy replenishment for new energy vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or on the wall and installed in parking lots or charging stations in public buildings and residential communities. It can charge various models of new energy vehicles according to different voltage levels. The outer shell of the charging pile is usually made of metal sheet metal, and a stamping die is used to stamp the sheet metal into the shape of the shell.

[0003] The Chinese patent document with publication number CN220560190U discloses a protective shell mold for a car charging pile, comprising a base, a stamping component provided on one side of the base, the stamping component including a top frame, a first cylinder fixedly connected to one side of the top frame, and a lifting plate fixedly connected to the output end of the first cylinder. The motor is turned on to drive the driving gear to rotate, and the rotating table can be driven to rotate through the meshing transmission. When the lower concave die to be used is facing upward, the corresponding upper punch is then replaced. After the mold is adjusted, the sheet metal plate is placed on the rotating table, the first cylinder is turned on to drive the lifting plate downward, and the stamping operation can be completed by the extrusion between the upper punch and the lower concave die. The lower concave die can be adjusted according to the forming requirements without the need for back and forth replacement, which is very time-saving and labor-saving, and can reduce and improve the efficiency of the shell stamping.

[0004] This protective shell mold for new energy vehicle charging piles has shortcomings. First, the lower die adopts a flip-switch design, which results in less than ideal support reliability. Second, after the first stamping, a second punching operation is performed to create holes, which cannot meet the requirements for cable routing. Therefore, its structure needs to be optimized and improved. Utility Model Content
