Abstract

The invention discloses a liquid-filled forming die and a liquid-filled forming method. The liquid-filled forming die comprises an upper die and a lower die, wherein the upper die comprises an upper die support plate, an upper die bottom plate, a punch insert, a punch seat and a punching component; and the lower die comprises a lower die support plate, a lower die bottom plate, a die insert, a diesocket and a liquid filling component. Compared with the prior art, a pre-forming die and the punching frequency are saved, collapse and wrinkles at the two ends are eliminated, hydraulic on-line punching is used as a positioning hole for laser cutting, a tool is simplified, the cutting cost is reduced, the product precision and consistency are improved, punch side collapse is eliminated by punching towards the outside of a pipe, and meanwhile, a punch is rapidly replaced through a skylight and a connecting block, flangings at the two ends are finally formed through a core rod and a die, a pair of outward hole flanging tools is omitted, and seam allowance welding instability and laser cutting cost are avoided.

Description

technical field [0001] The invention relates to a mold, in particular to a liquid-filled molding mold and a liquid-filled molding method. Background technique [0002] With the requirements of low-carbon development in recent years, in order to meet the requirements of energy saving and emission reduction in the automotive industry, lightweight technology has been developed and applied at a high speed. Lightweight automobile structure is the goal pursued by various automobile factories today. Lightweight body has a great contribution to the fuel economy, control stability and collision safety of the whole vehicle. Liquid-filled molding technology is a very advanced process, which can effectively reduce the number of assembly parts to reduce the weight of the vehicle and save mold development costs; reduce the investment in tooling, labor intensity and welding quality caused by subsequent welding; improve the quality of the vehicle Strength and stiffness, especially fatigue ...
