Stamping die mechanism

Abstract

A stamping die mechanism comprises an upper die set, an upper backup plate, a holder, an upper die plate, a stop plate, a lower die plate, a lower backup plate, a lower die set, a bottom block and a bottom mounting plate sequentially from the top down, and also comprises a lower die insert, a stripper plate and trim line inserts; the lower die insert is arranged on the lower die plate, and a casting is arranged on the lower die insert; the stripper plate is movably arranged under the stop plate, and cooperates with the lower die insert to die-cast the casting; and the trim line inserts are respectively arranged by both ends of the lower die insert, and can carry out contour machining according to the shape of the casting. Since the trim line insert is added on the lower die and can carry out contour machining according to the shape of the casting, contour machining does not need to be carried out according to the shape of the casting at the trim lines of the stripper plate and the lower die insert, and thereby the stamping die mechanism overcomes the defect that because the strength at the trim lines is poor after contour machining carried out by the lower die insert, a product can be easily cracked as a runner and a cinder ladle are die-cut out.

Description

【Technical field】 [0001] The invention relates to a mold mechanism, in particular to a novel stamping mold mechanism. 【Background technique】 [0002] Die-cast products through stamping dies need to punch runners and slag bags. In existing stamping die mechanisms, see figure 1 As shown, it depicts a schematic diagram of the clamping state of the existing stamping die mechanism. The existing stamping die mechanism includes: upper die base 10, upper backing plate 20, upper splint 30, upper template 40, and stop Plate 50, stripping plate 41, lower die entry 61, lower template 60, lower backing plate 70, lower die base 80, lower pad foot 90 and lower supporting plate 91, wherein the stripping plate 41 and lower die entry 61 are two The end knife edges are profiled according to the shape of the casting 1 respectively. During the movement of the stamping die, the stripping plate 41 will first press the casting 1 and then move downwards, and then the punch 42 punches the product,...
