Description
【００１１】
「請求項２」は所定箇所に多孔状スピーカーグリル一体成形型内装トリムの成形用金型(6)(7)であって、「スピーカーグリル形成用型窩間隙(h)が内装トリム本体形成用間隙(H)よりは薄く設定され、スピーカーグリル(2)の小孔(2a)の孔径が２.０mm以下であり、隣接する小孔間の肉厚が０.４〜１mmに設定されており、成形用樹脂材料としてメルトフローレートが１０〜３５ [g ／１０ min] のポリプロピレン樹脂を用いて成形されるものであり、スピーカーグリル(2)の裏面形成用金型(6)の、スピーカーグリル(2)の中央部分にガス抜き用の多孔性裏面金型部(5)が設けられている」事を特徴とする。[0011]
"Claim 2" is a molding die (6) (7) for forming a porous speaker grille integrally formed interior trim at a predetermined location, wherein "a space for forming a speaker grille (h) is for forming an interior trim main body It is set thinner than the gap (H), the hole diameter of the small holes (2a) of the speaker grille (2) is 2.0 mm or less, and the thickness between adjacent small holes is set to 0.4 to 1 mm. And the speaker grill of the mold (6) for forming the back surface of the speaker grille (2) using a polypropylene resin having a melt flow rate of 10 to 35 [g / 10 min] as a molding resin material. A porous back mold portion (5) for degassing is provided in the central portion of (2).
【００３０】
また、上記多孔部分の開口率を十分確保したので、スピーカーグリルの音量の透過性を良好に確保することができる。この場合において、成形用樹脂材料としてメルトフローレートが１０〜３５ [g ／１０ min] のポリプロピレン樹脂を用いるようにしたので、スピーカーグリル(2)をドアトリム(1)と一体成形するに際して、十分な成形性を確保して欠肉等の不具合を生じることなく成形することができるのである。また、上記多孔状スピーカーグリル(2)に対応する裏面側形成用金型(6)にガス抜き用の多孔性裏面形成金型部(5)を設けたので、上記多孔状スピーカーグリル(2)に対応する孔形成突部(9)(10)間に流入したエアは、この孔形成突部(9)(10)に溜まることなく円滑に多孔性裏面形成金型部(5)から外部に排出され、欠肉を生じる事なく確実な成形を確保することができる。[0030]
Moreover, since the aperture ratio of the said porous part was ensured enough, the permeability | transmittance of the volume of a speaker grille can be ensured favorable. In this case, a polypropylene resin having a melt flow rate of 10 to 35 [g / 10 min] is used as the resin material for molding, and therefore, it is sufficient to integrally form the speaker grille (2) with the door trim (1). It is possible to secure moldability and to mold without causing defects such as missing parts. Further, since the back surface side forming mold (6) corresponding to the porous speaker grille (2) is provided with the porous back surface forming mold portion (5) for degassing, the above porous speaker grille (2) The air that has flowed in between the hole forming protrusions (9) and (10) that corresponds to the above is smoothly collected from the porous back surface forming mold portion (5) without accumulating in the hole forming protrusions (9) and (10). It can be discharged and secure forming can be ensured without causing a chipping.
