Abstract

The invention discloses a liquid-filled molding mold and a liquid-filled molding method. The liquid-filled molding mold includes an upper mold and a lower mold, wherein the upper mold includes an upper mold support plate, an upper mold bottom plate, a punch insert, and a punch seat and punching assembly; the lower die includes a lower die support plate, a lower die bottom plate, a die insert, a die base and a liquid filling assembly. Compared with the prior art, the present invention saves preforming molds and punching times, eliminates collapse and wrinkles at both ends, uses hydraulic online punching as positioning holes for laser cutting, simplifies tooling and reduces cutting costs, and improves product accuracy and consistency. Punching out of the pipe to eliminate the collapse of the punching surface. At the same time, the punch can be replaced quickly through the skylight and the connecting block. The flanging at both ends depends on the mandrel and the die to form the final shape, saving a pair of turning-out tooling and avoiding Seam welding instability and laser cutting costs.

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 ...
