Station reversing mechanism for moulding mould of sound-proof felt automatic moulding machine

Abstract

The invention discloses a station reversing mechanism for a molding mold of an automotive sound-proof felt automatic mounding machine, and belongs to machinery for molding automobile interior parts. The moulding mould comprises a mould body and rolling devices which are arranged at four corners of the bottom surface of the mould body. The station reversing mechanism comprises a rail assembly which consists of a group of longitudinal guide rails and a group of transverse guide rails, wherein the longitudinal guide rails are parallel to each other longitudinally; and the transverse guide rails have the same number as the longitudinal guide rails and are parallel to each other transversely. Each transverse guide rail and each longitudinal guide rail form a perpendicular cross relation. A mould rail-changing rotation device is arranged at the intersection of each transverse guide rail and each longitudinal guide rail and is used for running through the longitudinal guide rail and the transverse guide rail so as to change the motion direction of the rolling devices together with the mould body. A reversing execution device used for driving the rail-changing rotation device to move is connected to each rail-changing rotation device. The station reversing mechanism for the moulding mould of the automotive sound-proof felt automatic moulding machine can meet the modularization requirement on the automotive sound-proof felt automatic moulding machine.

Description

technical field [0001] The invention belongs to the technical field of forming machinery for automotive interior parts, and in particular relates to a station reversing mechanism of a forming mold of an automatic forming machine for sound-insulating felts for automobiles. Background technique [0002] Car sound insulation felt is usually obtained by compression molding of low-melting thermoplastic fibers such as polypropylene fibers, etc., or a mixture of low-melting point fibers and natural fibers such as hemp fibers. Chinese Invention Patent Application Publication No. CN101549671A discloses a hemp fiber automotive interior trim and its production method. The method recommends two molding processes, one is to open the raw materials, mix them, comb them into a net, needle them into a felt, Slicing treatment, hot air baking and surface bonding, hot pressing forming into plates, slicing treatment, oven heating and cold pressing forming; second, raw material opening treatment,...

AI Technical Summary

Problems solved by technology

Therefore, the design of how to keep the direction of the lower mold itself constant and the direction of motion shifted at a right angle (90°) has become a technical obstacle to the success of the automatic forming machine for automotive sound insulation felt, because as long as this technical obstacle cannot be obtained If it is eliminated, then the miniaturization and collection or building block of the automatic forming machine for automobile sound insulation felt cannot be realized.
