Description

Technical Field

[0001] This utility model relates to a stamping die, specifically to a middle forming die for the waist reinforcement plate of the front door outer panel. Background Technology

[0002] In stamping, each additional stamping step increases both mold and processing costs. This is especially true for low-volume products, which need to be streamlined and combined to reduce mold and processing costs. However, for products with complex structures, different shapes require different stamping steps. This is particularly true when the stamping directions differ, making it difficult to achieve processing within a single mold. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a middle forming mold for the waist reinforcement plate of the front door outer panel that has reliable molding and low processing cost.

[0004] To solve the above technical problems, the technical solution adopted by this utility model is as follows: a middle forming mold for the waist reinforcement plate of the front door outer panel, including an upper mold base and a lower mold base. The upper mold base is provided with an upper mounting groove. An upper floating seat is provided in the upper mounting groove through a number of nitrogen springs. A left upper forming block and a right upper forming block are respectively provided on both sides of the upper mounting groove on the upper mold base. A floating limit block is provided at the groove opening of the upper mounting groove on the upper mold base to limit the position of the upper floating seat. A pair of upper end forming inserts at the narrow inner corners of the forming left and right workpieces are provided on the upper mold base.

[0005] The lower mold base is provided with a lower mounting groove, and a lower forming block is detachably provided in the lower mounting groove. The lower forming block is provided with two pairs of positioning pins for positioning workpieces, and the side of the lower forming block is provided with a side limiting block that can be adjusted to restrict the edge of the workpiece.

[0006] The lower forming block has a clearance groove at the wide end of the workpiece. The lower mounting groove has a lower forming component at the clearance groove at the end of the lower forming block, which is a raised area at the inner corner of the wide end of the left and right workpieces.

[0007] The lower forming assembly includes a bottom wedge slider that moves along the central axis of the left and right workpieces in the lower mounting groove. A vertical drive slider that moves vertically against the wall of the lower mounting groove is movably mounted on the bottom wedge slider. The bottom surface of the vertical drive slider and the bearing surface of the bottom wedge slider are inclined surfaces that cooperate with each other. An upper drive block that drives the vertical drive slider is mounted on the upper mold base. A return spring that pushes the bottom wedge slider away from the lower forming block is provided in the lower mounting groove.

[0008] The bottom wedge slider is equipped with a vertical movable block that moves up and down between the side wall of the lower forming block and the side wall of the vertical drive slider. The bottom surface of the vertical movable block and the driving surface of the bottom wedge slider are inclined surfaces that cooperate with each other. The vertical movable block is equipped with a shaping tool block for the raised area at the inner corner of the wide end of the left and right workpieces.

[0009] As a preferred option, the floating support is provided with several elastic positioning pins.

[0010] As a preferred option, the upper floating seat is equipped with a mold-opening nitrogen spring.

[0011] As a preferred option, the floating limit block and the upper drive block are integrally formed.

[0012] As a preferred option, the lower forming block is detachably provided with a pair of marking blocks that stamp and mark the left and right workpieces respectively.

[0013] The beneficial effects of this utility model are: the lower forming component in this mold has a simple and compact structure, but it can complete the downward stamping forming of the outer side of the left and right workpieces and the upward stamping forming of the raised area at the inner corner of the wide end of the left and right workpieces on the same stamping station; thereby reducing the stamping process and reducing the processing cost of the workpiece.

[0014] Because the upper floating seat is equipped with several elastic positioning pins, the reliable position of the workpiece can be ensured before processing, thereby guaranteeing the processing quality.

[0015] Because the upper floating seat is equipped with a nitrogen spring for mold opening, the upper floating seat can move upward quickly when the mold is opened, ensuring that the workpiece can be taken out smoothly.

[0016] Since the floating limit block and the upper drive block are integrally formed, they are easy to install and make the mold structure more compact. Attached Figure Description
