【従来の技術】[Prior Art]

前記インサート一体発泡成形品の一例である一般的な自動車の可倒式アームレ ストを図3に示す。 図示したように、このアームレスト30は、内部にインサート部材31が埋設 された発泡成形品32よりなり、その両側部30aには前記インサート部材31 の一部が突出して前記アームレスト30の回動軸35を構成している。 FIG. 3 shows a retractable arm rest of a general automobile, which is an example of the insert-integral foam-molded product. As shown in the figure, the armrest 30 is made of a foamed molded product 32 in which an insert member 31 is embedded, and a part of the insert member 31 projects from both sides 30a of the armrest 30 so that the pivot shaft 35 of the armrest 30 can rotate. Are configured.

【0003】 インサート部材31の一例を図4に示す。 前記インサート部材31は所定形状に成形された金属板などからなる本体部3 3と前記回動軸35を構成する突出部34とからなり、前述したようにその突出 部34を成形品外に突出させた状態で一体に発泡成形される。An example of the insert member 31 is shown in FIG. The insert member 31 is composed of a main body portion 33 formed of a metal plate or the like formed in a predetermined shape and a protruding portion 34 that constitutes the rotating shaft 35. As described above, the protruding portion 34 is projected outside the molded product. In this state, the foam is integrally molded.

【0004】 このような可倒式アームレストを製造するための成形型の一例を図5に示す。 符号50は発泡成形型、51は下型、52は成形品キャビティ、53は上型でヒ ンジ54によって前記下型51に対して開閉自在に構成されている。 下型51の型面にはマグネットなどからなるインサート受け部材56が設けら れていて、前記インサート部材31の本体部33を吸着しキャビティ内の所定位 置に位置決め固定するようになっている。FIG. 5 shows an example of a molding die for manufacturing such a retractable armrest. Reference numeral 50 is a foaming mold, 51 is a lower mold, 52 is a molded product cavity, and 53 is an upper mold which is configured to be openable and closable with respect to the lower mold 51 by a hinge 54. An insert receiving member 56 made of a magnet or the like is provided on the mold surface of the lower mold 51, and the main body 33 of the insert member 31 is adsorbed and positioned and fixed at a predetermined position in the cavity.

【0005】 しかるに、インサート材の大きさや形状によっては、成形時の発泡圧によって インサート材31の位置ずれを生じることがあった。 また、図4に示されるようなインサート形状にあっては、配される下型51が 深くなって製品の脱型が困難となるばかりか、前記突出部34が成形品30にア ンダーカット部36を形成するため、脱型の際に破れや裂けを生じて製品不良と なることがあった。However, depending on the size and shape of the insert material, the foaming pressure during molding may cause displacement of the insert material 31. Further, in the case of the insert shape as shown in FIG. 4, not only the lower mold 51 to be arranged becomes deep and it becomes difficult to remove the product, but also the protrusion 34 is formed in the molded product 30 and the undercut portion is formed. Since 36 is formed, there is a case where the product is defective due to tearing or tearing during demolding.

【0006】 そのため、下型51に前記インサート材31の突出部34を取り付けるための 入れ子57,57が設けられることがあるが、かかる入れ子57への突出部34 の固定には煩雑な手間を要していた。 さらに、前記インサート材31は本体部33が板状であるため、注入される発 泡樹脂材料の流れが阻害されて、成形品に欠肉などの外観不良を生じることがあ った。Therefore, the lower mold 51 may be provided with the nests 57, 57 for mounting the protrusions 34 of the insert material 31. However, fixing the protrusions 34 to the nests 57 requires complicated labor. Was. Further, since the body portion 33 of the insert material 31 is plate-shaped, the flow of the foaming resin material injected is obstructed, which may cause defective appearance such as lack of thickness in the molded product.

【0007】 特にかかる可倒式アームレストのような回動して用いられる発泡形成品は、使 用時および収納時に目に触れる表裏(上下)両面ともが重要な意匠面を構成する 。In particular, in a foam-formed product such as a retractable armrest that is used by being rotated, both the front and back (upper and lower) surfaces that are visible during use and storage form important design surfaces.

【0008】 ところが、前記形成型50にあっては、前記意匠面が上型53型面と下型51 型面で形成され、特に上型53型面付近には空気溜りを生じやすいため、意匠面 の良好なアームレストが得られないという問題がある。However, in the forming die 50, the design surface is formed by the upper die 53 die surface and the lower die 51 die surface, and air is likely to be generated particularly near the upper die 53 die surface. There is a problem that a good armrest cannot be obtained.

【0012】 この考案構造によるインサート一体発泡成形型10は、図3に示したような、 内部にインサート部材31の本体部33が一体に埋設され、両側部30aにイン サート部材31の突出部34が突出した形状の発泡成形品30を得るためのもの である。As shown in FIG. 3, the insert-integrated foam molding die 10 according to the present invention has the body 33 of the insert member 31 integrally embedded therein and the protrusions 34 of the insert member 31 on both sides 30 a. This is for obtaining a foamed molded product 30 having a protruding shape.

【0013】 図1および図2に示されるように、この発泡成形型10は下型11と上型21 とからなり成形品形状を規定するキャビティCを有している。As shown in FIGS. 1 and 2, the foam molding die 10 has a cavity C which is composed of a lower die 11 and an upper die 21 and defines a shape of a molded article.

【0014】 下型11は固定下型部12と可動下型部13とから構成されている。 固定下型部12は、図2からよりよく理解されるように、その底部型面12a に、キャビティC内に配されるインサート部材31の片側突出部34aを保持す る下側保持部15を備えている。 この下側保持部15には前記突出部34aが係着される保持孔16が形成され ている。 一方、可動下型部13はヒンジ14によって前記固定下型部12に対して開閉 自在に構成されている。The lower die 11 is composed of a fixed lower die portion 12 and a movable lower die portion 13. As will be better understood from FIG. 2, the fixed lower mold part 12 has a lower holding part 15 for holding the one side protruding part 34a of the insert member 31 arranged in the cavity C on the bottom mold surface 12a thereof. I have it. The lower holding portion 15 is formed with a holding hole 16 to which the protruding portion 34a is fitted. On the other hand, the movable lower mold part 13 is configured to be openable and closable with respect to the fixed lower mold part 12 by a hinge 14.

【0015】 上型21は保持上型部22と一般上型部23とからなり、それぞれヒンジ24 ,27を介して前記固定下型部12に開閉自在に取り付けられている。 保持上型部22の型面22aには、前記インサート部材31の他方の片側突出 部34bを保持する上側保持部25が形成されている。 この上側保持部25にも下側保持部15同様に突出部34bが係着される保持 孔26が形成されている。 一般上型部23は、この考案構造による発泡成形型10において、樹脂材料の 注入口の蓋型を構成している。The upper die 21 is composed of a holding upper die portion 22 and a general upper die portion 23, and is openably and closably attached to the fixed lower die portion 12 via hinges 24 and 27, respectively. On the die surface 22a of the holding upper die portion 22, an upper holding portion 25 that holds the other one-side protruding portion 34b of the insert member 31 is formed. Like the lower holding portion 15, the upper holding portion 25 also has a holding hole 26 into which the protruding portion 34b is fitted. The general upper mold part 23 constitutes a lid mold for a resin material injection port in the foam molding mold 10 according to the present invention.

【0016】 成形にあたっては、まず、前記インサート部材31の片側突出部34aを、前 記固定下型12に形成された下側保持部15の保持孔16に係着固定する。 そして、保持上型部22を型閉めしてその上側保持部25の保持孔26に前記 インサート部材31の他方の片側突出部34bを係着させ、当該インサート部材 31を型キャビティC内に上下方向から確実に保持固定する。In molding, first, the one-side protruding portion 34 a of the insert member 31 is fixedly attached to the holding hole 16 of the lower holding portion 15 formed in the fixed lower mold 12.

【考案の効果】[Effect of the device]

以上図示し説明したように、この考案のインサート一体発泡成形型の構造によ れば、インサート部材が上型と下型とによって上下方向から保持固定されるので 、入れ子およびインサート受け部材を用いた成形型と比較してインサート部材の セットは容易かつ確実であり、その作業性を大幅に向上させることができる。 また、インサート部材は型内に縦方向に配されるので、キャビティ内に注入さ れる樹脂材料の流れを阻害することがなく、精度の高い製品を得ることができる 。特に可倒式アームレストのように製品の両面ともが重要な意匠面を構成する発 泡成形品を製造する場合には、その意匠面がキャビティの側面によって形成され ることになり、空気溜り等による欠肉が重要な意匠面に現れることがない。 加えて、成形型にアンダーカット部が形成されていないので、成形型に入れ子 などを設ける必要がなく成形型の製造コストを低滅することができるだけでなく 、脱型の際の製品の破れや裂けなどを防止し、成形性も良好である。 As shown and described above, according to the structure of the insert-integrated foam molding die of the present invention, since the insert member is held and fixed in the vertical direction by the upper mold and the lower mold, the insert and the insert receiving member are used. Compared with the molding die, the setting of the insert member is easier and more reliable, and its workability can be greatly improved. Further, since the insert member is arranged vertically in the mold, it is possible to obtain a highly accurate product without obstructing the flow of the resin material injected into the cavity. In particular, when manufacturing a foam-molded product where both sides of the product form an important design surface, such as a retractable armrest, the design surface is formed by the side surface of the cavity, which causes air pockets and the like. The lack of meat does not appear on the important design side. In addition, since the molding die does not have an undercut portion, it is not necessary to provide a nest in the molding die, which not only reduces the manufacturing cost of the molding die, but also breaks or tears the product when demolding. And the like, and good moldability.
