Automobile wheel casing part trimming die

Abstract

The invention relates to an automobile wheel casing part trimming die. The automobile wheel casing part trimming die comprises an upper die and a lower die. The upper die comprises an upper die holder, an upper die pressing device, an upper die insert and an upper edge cutting cutter block. The upper die pressing device is located on the lower side of the upper die holder. The upper die insert andthe upper die edge cutting cutter block are located on the upper die holder. The lower die comprises a lower die holder, a lower die core and an ejector mechanism. The lower die core is located on the upper side of the lower die holder. The ejector mechanism is located on the lower die holder. The automobile wheel casing part trimming die further comprises a conical locating block. The conical locking block is arranged on a guide plate arranged on the lower die holder in a sleeving manner. Compared with the prior art, the automobile wheel casing part trimming die has the advantages of being low in production cost, convenient to maintain, safe, reliable and the like.

Description

technical field [0001] The invention relates to a mold, in particular to a trimming mold for automobile wheel cover parts. Background technique [0002] At present, there are many mold pressing plates for wheel cover parts that only use guide plates for guidance. The distance between the guide plate and the contact surface is relatively long, and the guidance is not accurate, which leads to easy damage to the hidden punch, and even the punch is crushed and ejected from the mold. a great safety hazard. [0003] Chinese patent CN 103182425A discloses a trimming and shaping mold for automotive wheel cover parts, including an upper mold, a lower mold, a first trimming knife block, a second trimming knife block, a first shaping mechanism and a second shaping mechanism, and the upper mold Including the upper die base, upper die presser and upper ejector pin, the upper die presser is located below the upper die base, the upper ejector pin is located on the upper die base; the lowe...
