Design of handle mold for electric vehicle
Abstract
After the preliminary design of gate type selection of electric vehicles in life can be seen everywhere, and the design of the subject is the source of the electric vehicle handle. It can be in the riding process, help us grasp the direction and help us to master the balance. This manual recorded the complete set of the actual process, the design process including the plastic parts material selection, mold parting surface, injection molding machine, plastic parts shape analysis, pouring system design, cooling system design, the introduction of mechanism design, the side core pulling mechanism design. Mold using the spokes and a top rod demoulding form. In the end into a mold for injection molding machine parameters are checked, such as injection molding machine Clamping force, injection machine and mold thickness, injection pressure, injection machine maximum mold opening and closing stroke. In this design, using the UG, AutoCAD and other software design, improve the design precision and efficiency. Through checking, the mold industry and trade.
