Description

上記目的を達成するために、本発明では、成形時のゲート跡を有する樹脂パネルにおいて、前記樹脂パネルは、パネル本体と、前記パネル本体の端部に形成された側壁とを含み、前記側壁の先端において、前記側壁の長さ方向の一部に前記側壁から高さ方向に延設された延設部を有し、前記延設部は、前記樹脂パネルの一部として成形後も前記側壁に接続した状態で残され、前記延設部の高さ方向の先端に前記ゲート跡が位置することを特徴とする。 To achieve the above object, the present invention, in the resin panel having a gate trace at the time of molding, the resin panel includes a panel body and a side wall formed on an end portion of the panel body, the side walls At the tip, the side wall has an extension part extending in the height direction from the side wall in a part of the side wall in the length direction, and the extension part is formed on the side wall even after molding as a part of the resin panel. It is left in the connected state, and the gate mark is located at the tip in the height direction of the extending portion.

以上、本発明の実施形態につき説明したが、本発明の範囲はこれに限定されるものではなく、発明の主旨を逸脱しない範囲で種々の変更を加えて実施することができる。
<付記>
本発明では、成形時のゲート跡を有する樹脂パネルにおいて、前記樹脂パネルは、パネル本体と、前記パネル本体の端部に形成された側壁とからなる断面コ字状に形成され、前記側壁の一部に前記側壁から高さ方向に延設された延設部を有し、前記延設部の高さ方向の先端に前記ゲート跡が位置することを特徴とする。 上記構成によれば、側壁の高さ方向に延設部を延設することで、側壁の強度を向上させることができる。すなわち、延設部の存在自体が側壁の剛性を高め、これによって側壁におけるクラックの発生を抑制することができる。
さらに、ヒケ、ムラ、フローマーク等の外観不良が発生した場合であっても、外観不良を延設部及び側壁部分の領域に留めて、パネル本体部分に外観不良が及ぶのを抑制することが可能となる。なお、樹脂パネルは、パネル本体の縦横(もしくは上下左右)二方向のうち、少なくとも一方向の両端部に側壁が形成され、パネル本体を挟んで対向する側壁のうちのいずれかに延設部が形成されていればよく、パネル本体の他方向の一端部又は両端部に側壁が形成されていてもよい。
延設部は、側壁に近い側の幅が広くなるように形成してもよい。これにより、樹脂パネルに対して弓なりに曲げようとする力が加わったときに、延設部と側壁との接続部分(境界部分)に応力が集中するのを防ぎ、割れの発生を抑制することができる。すなわち、延設部を形成することで、前述のごとく、ゲート付近におけるクラックの発生を抑制するとともに、側壁に近づくほど幅広になるように形成することで、延設部と側壁との境界部分の割れをも抑制することが可能となる。また、延設部は、側壁と同じ厚みに形成してもよい。これにより、成形時にキャビティ内の延設部部分から側壁部分に樹脂が流入する際に、樹脂の流速変化を抑制して外観不良の発生を抑制することが可能となる。
延設部は、側壁の先端において、側壁の長さ方向に間隔をおいて複数形成してもよい。これにより、細長い矩形形状の樹脂パネルであっても、樹脂パネルの強度を向上させることができるとともに、キャビティ内に効率よく樹脂を充填することが可能となる。
上記樹脂パネルは、ヒケ、ムラ、フローマーク等の外観不良が発生しにくく、また、外観不良が発生したとしても、延設部及び側壁部分の領域に留まり、パネル本体部分に外観不良が及ぶのを抑制することができる。すなわち、実質的に外観不良を低減することができる。したがって、上記樹脂パネルを前面パネルとしてキャビネットに装着した空気調和機は、前面パネルのクラック及び外観不良の発生を抑制することが可能となる。
Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.
<Appendix>
In the present invention, in the resin panel having a gate mark at the time of molding, the resin panel is formed in a U-shaped cross section including a panel main body and a side wall formed at an end of the panel main body. And an extension portion extending in the height direction from the side wall, and the gate mark is located at a tip in the height direction of the extension portion. According to the said structure, the intensity | strength of a side wall can be improved by extending an extending part in the height direction of a side wall. That is, the presence of the extended portion itself increases the rigidity of the side wall, thereby suppressing the occurrence of cracks in the side wall.
In addition, even when appearance defects such as sink marks, unevenness, and flow marks occur, the appearance defects can be retained in the region of the extending portion and the side wall portion to suppress the appearance failure from reaching the panel body portion. It becomes possible. In the resin panel, side walls are formed at both ends in at least one direction out of two vertical and horizontal (or up, down, left, and right) directions of the panel body, and an extending portion is provided on one of the opposing side walls across the panel body. As long as it is formed, side walls may be formed at one end or both ends in the other direction of the panel body.
The extending portion may be formed so that the width on the side close to the side wall is widened. This prevents stress from concentrating on the connecting part (boundary part) between the extended part and the side wall when a force is applied to the resin panel to bend like a bow, thereby suppressing the occurrence of cracks. Can do. That is, by forming the extended portion, as described above, the generation of cracks in the vicinity of the gate is suppressed, and the width of the boundary between the extended portion and the side wall is increased by increasing the width toward the side wall. It is possible to suppress cracking. Moreover, you may form an extending part in the same thickness as a side wall. Thereby, when resin flows into the side wall portion from the extending portion portion in the cavity during molding, it is possible to suppress the occurrence of poor appearance by suppressing the change in the flow rate of the resin.
A plurality of extending portions may be formed at the front end of the side wall at intervals in the length direction of the side wall. Thereby, even if it is an elongate rectangular resin panel, the intensity | strength of a resin panel can be improved and it becomes possible to fill resin in a cavity efficiently.
The above-mentioned resin panel is less likely to cause appearance defects such as sink marks, unevenness, and flow marks, and even if an appearance defect occurs, it remains in the region of the extending portion and the side wall portion, and the appearance defect extends to the panel body portion. Can be suppressed. That is, appearance defects can be substantially reduced. Therefore, the air conditioner in which the resin panel is mounted on the cabinet as the front panel can suppress the occurrence of cracks and poor appearance on the front panel.
