Embodiment Construction

[0027] Hereinafter, preferred embodiments of the powder slush molding machine and the powder slush molding method of the present invention will be specifically described with reference to the drawings.

[0028] [First Embodiment]

[0029] As shown in FIG. 1, the first embodiment is a powder slush molding machine 10 equipped with a powder slush molding section (A section), a mold heating section (B section), and a mold cooling section (C section). Its features are shown in Figure 4(a): in the metal mold heating part (B part), there is a hot air outlet 16 that can blow hot air 14 with a flow rate of 15 m / s or more from the bottom of the metal mold 12, along the metal mold. The corner or edge of the bottom surface 18 of the heating part (B part), and the energy recovery part 24 for recovering the hot air 14 heated to the metal mold 12 .

[0030] Hereinafter, a suitable example of the powder slush molding machine 10 will be specifically described. In addition, in FIG. 7 and FIG....

Abstract

A powder slush molding machine and a powder slush molding method capable of applying powder uniformly to a powder slush molding die. The powder slush molding machine comprising a die heating section, a powder slush section, and a die cooling section, and the powder slush molding method employing that powder slush molding machine, characterized in that a section for blowing hot air, at a flous velocity of 15 m / sec or above, to the die heating section from below the die, and an energy collecting section disposed at the corner part of the bottom face, in the furnace, of the die heating section or along the side part thereof, for collecting hot air after heating the die are provided.

Description

technical field [0001] The present invention relates to a powder slush molding machine and a powder slush molding method, in particular to a powder slush molding machine and a powder slush molding method capable of uniformly attaching powder (powder resin) to a large and complex metal mold. Background technique [0002] So far, the powder slush molding method of slush molding with resin (powder resin) has been widely used when manufacturing large and complicated sheet-like objects such as automotive interior materials. [0003] Here, in order to make the thickness of the interior material made of powder uniform, it is preferable to heat the mold at the same temperature. [0004] For example, in Japanese Patent Application Laid-Open No. 3-202329, a leather forming method with the following characteristics is disclosed: a temporary heating process and a preliminary heating process controlled at a specific temperature are provided, and the metal mold is heated at the same tempe...
