A double-layer water-cooled mold for making automobile bumpers by hot stamping

Abstract

The invention discloses a dual-layer water-cooling mould for making a vehicle bumper through a hot stamping mode, and relates to the technical field of stamping production processing. The dual-layer water-cooling mould comprises a first mould body and a second mould body, the front end face of the first mould body is provided with a protruding mould die, the rear end face of the second mould bodyis provided with a mould cavity matched with the mould die, and the top of the first mould body and the top of the second mould body are both provided with two water injection connectors; a first water-cooling cavity way is formed in the first mould body, and the two water injection connectors of the first mould body are communicated with two ports of the first water-cooling cavity way respectively. According to the dual-layer water-cooling mould, an annular sealing groove is formed in the portion, located at the root of the mould die, of the front end face of the first mould body, and a sealing block matched with the sealing groove is arranged at the rear end of the second mould body and embedded in the sealing groove. Each sealing ring stretches into the sealing groove for sealing, so that the fitting face of the first mould body and the second mould body forms a bent S-shaped face, and sealing performance on a thermal stamping piece is improved.

Description

technical field [0001] The invention relates to the technical field of automobile stamping dies, in particular to a double-layer water-cooled die for making automobile bumpers by means of hot stamping. Background technique [0002] The front and rear ends of the car are equipped with bumpers, which not only have a decorative function, but more importantly, are safety devices that absorb and moderate external impact, protect the body and protect the body and occupants. With the development of the automobile industry and the large number of applications of engineering plastics in the automobile industry , as an important safety device, the automobile bumper is also on the road of innovation. At present, in addition to maintaining the original protective function, the front and rear bumpers of automobiles also need to pursue harmony and unity with the shape of the car body, and pursue their own lightweight. The front and rear bumpers of cars are made of plastic, which are call...
