Hot stamping knife die for two-component acoustic wool

Abstract

The invention relates to a knife die used for cutting, in particular to a hot stamping knife die for two-component acoustic wool. The hot stamping knife die for the two-component acoustic wool comprises a wood template, a finishing blade, a metal heat-conductive plate, a metal base plate and a metal line, wherein the metal heat-conductive plate is directly connected with a heating device of a press; the upper end of the finishing blade is connected with the lower surface of the metal heat-conductive plate; the upper end of the metal line is also connected with the lower surface of the metal heat-conductive plate and the metal line adjoins the inner side of the finishing blade; the wood template is connected with the lower surface of the metal heat-conductive plate; the metal base plate is connected with the lower surface of the wood template; the wood template and the metal base plate are both provided with through grooves where the finishing blade and the metal line can penetrate, and the lower ends of the finishing blade and the metal line penetrate through the through grooves and extend out of the lower surface of the metal base plate; the metal heat-conductive plate, the wood template and the metal base plate are connected into a whole through a fixing device. The hot stamping knife die for the two-component acoustic wool has the advantages of being uniform in heating, high in strength, long in service life and the like.

Description

technical field [0001] The invention relates to a cutting die for cutting, in particular to a hot punching die for two-component sound-absorbing cotton. Background technique [0002] Two-component sound-absorbing cotton is a special sound-insulating and sound-absorbing material for automotive interiors. After production, the two-component sound-absorbing cotton is rolled up like cloth. When it needs to be used, it needs to be cut into a specific shape. The two-component sound-absorbing cotton is cut into a specific shape by a press, and a knife mold for cutting the two-component sound-absorbing cotton is connected to the press. Usually, the knife mold includes a wood formwork connected to the press and embedded in the wood formwork and exposing the bottom surface of the wood formwork. The precision blade is equipped with a heating device on the press, and the heating device transfers heat to the fine blade, and the fine blade with heat cuts the two-component sound-absorbing ...
