Embodiment Construction

[0034] The device for molding fiberboard products through injection composite technology of the present invention includes a rotary table 1 that can rotate 180 degrees and a concave mold 2 that is fixed on the rotary table 1 and has the same structure on both sides. There is a first punch 3 for molding the fiberboard 8 and a second punch 4 for injecting accessories on the fiberboard.

[0035] Further, in order to form accessories on the fiberboard to increase the strength of the fiberboard, the above-mentioned second punch is provided with a groove 6 for forming the injection molding accessories 5 , and the injection port can be set in the groove 6 . Both the concave mold and the first and second convex molds are provided with heat conduction pipes for heating the mold body.

[0036] In order to form a perforation on the fiberboard, to inject plastic into the perforation to increase the connection strength between the fiberboard and the injection molding accessory 5, one embod...

Abstract

The invention relates to a device and method for forming fiberboard products by a pressure injection composite technology. The device for forming the fiberboard products by the pressure injection composite technology is characterized by comprising a rotating table and concave dies, wherein the rotating table can rotate at an angle of 180 degrees; the concave dies are fixedly arranged on two sides of the rotating table and have the same structures; and a first convex die which is used for forming fiberboards in a pressing manner and a second convex die which carries out injection molding on accessories on the fiberboards are respectively arranged on two sides of the rotating table. The device for forming the fiberboard products by the pressure injection composite technology is simple in structure and reasonable in design; and production efficiency is improved.

Description

technical field [0001] The invention relates to a device and a method for forming fiberboard products through injection composite technology. Background technique [0002] At present, most of the automotive interiors still use plastic injection molding to form related interior parts. However, with the development trend of lightweight, energy-saving and emission-reducing automobiles, interior parts using natural fiber materials have been more and more widely used in the automotive field. However, since natural fibers are made by thermoforming, compared with traditional plastic interior decorations, natural fibers cannot be directly formed on the board to assist in the installation of buckles and other structures. The current general method is to bond plastic parts on the surface by hot melt adhesive after hot pressing of natural fibers to achieve corresponding structural effects. The way of glue bonding will increase the production cost and production process, making the pr...
