Description

Technical Field

[0001] This utility model relates to stamping processing, specifically to a forming mold for an inner sealing plate of a vehicle force column. Background Technology

[0002] The inner sealing plate of the vehicle's force column has a certain degree of curvature and a complex mounting and avoidance structure on its surface. Currently, during processing, the curved surface of the part is first shaped using a pressure plate, and then the mounting and avoidance structures are shaped using forming cutters. However, due to the height difference of the part, it is impossible to accurately position it. When using positioning grooves, floating blocks, and positioning pins for positioning and continuing to process the mounting and avoidance structures, problems such as misalignment and wrinkling of the part occur after forming, which cannot meet the processing requirements and the product quality cannot be guaranteed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a molding die for a high-quality inner sealing plate for a vehicle force column.

[0004] To solve the above technical problems, the technical solution adopted by this utility model is as follows: a forming mold for the inner sealing plate of the vehicle force column, including an upper mold base and a lower mold base, with a pressure guide seat on each side of the upper mold base, and a guide groove on the lower mold base that cooperates with the pressure guide seat. The upper mold has a right forming groove and a left forming groove, and the right forming groove and the left forming groove are respectively detachably provided with an upper right forming block and an upper left forming block, and the upper left forming block and the upper right forming block are provided with a plurality of elastic pressure pins.

[0005] The lower mold base has a floating cavity in the middle, a floating block is movably installed in the floating cavity, and several nitrogen springs that push the floating block are installed on the bottom surface of the floating cavity; there are limiting blocks for limiting the floating seat at both ends of the floating cavity; the lower mold base has a lower left forming block and a lower right forming block detachably installed on both sides of the floating cavity; and there are several adjustable side limiting blocks for limiting the edge of the workpiece on the lower left forming block and the lower right forming block respectively.

[0006] The middle floating seat is equipped with a left inner forming block and a right inner forming block on the left and right sides respectively. The left inner forming block and the right inner forming block are equipped with two positioning pins that cooperate with the positioning holes on the workpiece.

[0007] The dividing line between the left inner forming block and the lower left forming block is located at the junction of the recessed and raised sidewalls of the left workpiece after forming; the dividing line between the right inner forming block and the lower right forming block is located at the junction of the recessed and raised sidewalls of the right workpiece after forming.

[0008] As a preferred embodiment, the bottom surface of the buoyancy chamber is provided with several limiting bottom blocks to restrict the descent position of the buoyancy blocks.

[0009] As a preferred embodiment, the side of the buoy is provided with several wear-resistant plates, and the inner side of the buoy cavity is provided with several guide blocks that cooperate with the wear-resistant plates.

[0010] As a preferred embodiment, the sidewall of the right forming groove is detachably provided with a plurality of adjusting pads that restrict the position of the upper right forming block.

[0011] As a preferred embodiment, the left forming groove is provided with a plurality of adjusting pads on its sidewall to restrict the position of the upper left forming block.

[0012] The beneficial effects of this utility model are:

[0013] This mold locks the upper right and upper left forming blocks to the upper mold base, creating a fixed connection between the upper and lower molds. The dividing line between the left inner forming block and the lower left forming block is located at the junction of the recessed and protruding sidewalls of the formed left workpiece, and the dividing line between the right inner forming block and the lower right forming block is located at the junction of the recessed and protruding sidewalls of the formed right workpiece. Through the reasonable arrangement of the dividing lines, this mold can accurately form the curved surface of the sheet metal in one go, while accurately forming the complex installation structure and avoidance structure on the surface of the workpiece, ensuring the processing quality and greatly reducing the processing cost.

[0014] Because the bottom surface of the floating cavity is provided with several limiting bottom blocks that restrict the descent position of the floating blocks, the reliability of the movement of the floating blocks during stamping is ensured, thereby ensuring the processing quality of the product.

[0015] Because the side of the floating block is provided with several wear-resistant plates, and the inner side of the floating cavity is provided with several guide blocks that cooperate with the wear-resistant plates, the service life of the mold is extended.

[0016] Because the right molding groove has several detachable adjusting shims on its sidewall that restrict the position of the upper right molding block, the installation of the upper right molding block is more convenient and accurate. Similarly, because the left molding groove has several detachable adjusting shims on its sidewall that restrict the position of the upper left molding block, the installation of the upper left molding block is more convenient and accurate.
