Automatic molding machine for automobile interior part felt

Abstract

The invention discloses an automatic molding machine for an automobile interior part felt and belongs to molding machinery of automobile interior parts. The automatic molding machine comprises a frame base, a rail assembly, three lower molds, a group of lower mold station moving mechanisms, a group of lower mold station reversing mechanisms, a pair of pressing upper molds, a feed supplementing mechanism and a net laying mechanism. The rail assembly consists of a group of longitudinal guide rails and a group of transverse guide rails, and is arranged on the frame base, and the longitudinal guide rails and the transverse guide rails are vertically staggered to form a feed complementing station, a pre-pressing station, a net laying station and a molding station. The three lower molds which are provided with a lower mold base are arranged on the rail assembly. The group of lower mold station moving mechanisms are arranged on the frame base. The group of lower mold station reversing mechanisms are arranged on the frame base and matched with the intersection formed by vertically intersecting the transverse guide rails and longitudinal guide rails. The pair of pressing upper molds which is provided with the upper mold base is arranged on the frame base, wherein one pressing upper mold corresponds to the upper part of the pre-pressing station, and the other pressing upper mold corresponds to the upper part of the molding station. The feed complementing mechanism is arranged on the frame base and corresponds to the upper part of the feed complementing station. The net laying mechanism is arranged on the frame base and corresponds to the upper part of the net laying station. The automatic molding machine for the automobile interior part felt has the advantages of high integration degree, small occupancy area, a few on-line workers, high production efficiency and energy conservation.

Description

technical field [0001] The invention belongs to the technical field of molding machinery for automotive interior parts, and in particular relates to an automatic molding machine for automotive interior trim felts. Background technique [0002] Felts for automotive interior parts, such as automotive sound insulation felts, are usually obtained by compression molding of low-melting thermoplastic fibers such as polypropylene fibers, or 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, mixing, carding into w...
