Embodiment Construction

[0031] Embodiments of the present invention will be described below based on the drawings.

[0032] [Manufacturing equipment of the automotive resin department]

[0033] exist Figure 1A Among them, the manufacturing apparatus 10 of an automotive resin part according to this embodiment has an upper mold 11 as an example of a first mold, a lower mold 12 as an example of a second mold, and a movable block 14 .

[0034] The upper mold 11 is a mold having a convex portion 16 for molding, and is configured to be movable in a molding direction (arrow D direction) and a mold opening direction (arrow U direction). The convex portion 16 is formed to protrude downward from the base portion 18 to have, for example, a substantially trapezoidal cross section. The side wall portion 20 of the protrusion 16 is provided with a draft gradient.

[0035] The lower mold 12 is a die having a concave portion 22 for molding corresponding to the convex portion 16 and fixed to an unillustrated base. ...

Abstract

The invention relates to a method and device for manufacturing an automotive resin part. The method for manufacturing an automotive resin part includes: heating a fiber reinforced plastic material that uses a thermoplastic resin as a binder resin and arranging the fiber reinforced plastic material between a first die having a projected section for molding and a second die having a recessed section for molding that corresponds to the projected section; approaching the first die and the second die in a molding direction and holding the fiber reinforced plastic material by the projected section and a movable pad provided in the recessed section; and stacking the first die and the second die in the molding direction and press-molding the fiber reinforced plastic material while a state that the fiber reinforced resin material is held between the projected section and the movable pad is maintained by moving the movable pad along with movement of the projected section in the molding direction.

Description

technical field [0001] The present invention relates to a method of manufacturing an automobile resin part and an apparatus for manufacturing an automobile resin part. Background technique [0002] In order to reduce costs and improve productivity, it has been considered to switch the binder resin of fiber reinforced plastics (FRP) from thermosetting resins to thermoplastic resins. Press molding is adopted as a molding method of FRP using such a thermoplastic resin. For example, a forming die for press forming is disclosed in Japanese Patent Application Laid-Open No. 7-256768 (JP 7-256768A). [0003] However, in the case of FRP using a thermoplastic resin as a binder resin, the fluidity of the resin and fibers during molding is low. Therefore, the occurrence of phenomena such as underfilling, thickness reduction, non-filling of fibers, and directionality of fibers during deep drawing using conventional press forming is considered. In addition, the above-mentioned conventi...
