Abstract

The invention discloses a sill plate inner plate drawing die which comprises an upper die combination, a lower die combination and a blank holder combination. The lower die combination comprises a lower die seat and a terrace die fixed on the lower die seat through a screw. The terrace die comprises a terrace die seat and a terrace die insert fixed on the terrace die seat through a screw. The lower die combination, the upper die combination and the blank holder combination are all of the combination structure, so that the terrace die, a recessed die insert, a blank holding die insert and the die seats can be made of different materials, and the die manufacture cost can be greatly saved. Meanwhile, the terrace die, the recessed die insert and the blank holding die insert are made in a split mode, so that the die is smaller in size, convenient to machine and low in manufacture difficulty. The adopted location structures of square columns, guide sliding plates, rectangular grooves and rectangular protrusion blocks are high in strength, good in location reliable and capable of ensuring die assembly accuracy in long-term production.

Description

technical field [0001] The invention relates to a mold, in particular to a drawing mold for an inner panel of an automobile door sill. Background technique [0002] The upper mold, the lower mold and the blank holder of the existing drawing mold for the inner panel of the sill plate are all of integral structure, which makes the mold manufacturing difficult and the manufacturing cost is relatively high. [0003] Moreover, the positioning structure reliability of the existing door sill plate inner plate drawing die is relatively poor, and the precision of mold clamping decreases rapidly after a period of production, and the product quality cannot be guaranteed. Contents of the invention [0004] In view of this, the object of the present invention is to provide a drawing die for the inner panel of the sill panel to solve the problem of difficulty in manufacturing the drawing die for the front outer panel of the engine compartment side beam, high manufacturing cost, and poor...
