品及びその成形方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a lid for a glove box or a console box, a main body for the glove box or the console box,
The present invention relates to automobile interior parts such as door rims, rear side trims, and ashtrays, and a method for forming the same.
近年、自動車用部品は極力軽量化する傾向にあるので、
これらの傾向に起因して、グローブボックスやコンソー
ルボックスの蓋体等の自動車用内装品に対しても軽量化
の要請が課せられている。以下、自動車用内装品の代表
例として蓋体を取り上げて説明する。In recent years, automobile parts tend to be as lightweight as possible,
Due to these tendencies, there has been a demand for weight reduction of automobile interior parts such as glove box and console box lids. Hereinafter, a lid will be described as a typical example of automobile interior parts.
従来、所望の形状に硬質材で形成された基体と、同基体

皮と、同表皮と前記基体との間に発泡体より成るクッシ
ョン層を形成して一体化した蓋体により、金属インサー
トを省略して軽量化した蓋体がある。Conventionally, a base body formed of a hard material in a desired shape, a flexible skin including a surface portion and a side surface portion surrounding the surface side of the base body, and a cushion formed of a foam between the skin and the base body There is a lid body that is lightened by omitting the metal insert by the lid body that is formed by forming layers and is integrated.

接一体化する蓋板の場合、表皮と基体の接合部からの発
泡体の露出を防止して外観の見栄えを良くする必要があ
る（従前の金属インサートを用いるものでは、基体で発
泡体の露出部を覆っていた）。In the case of a cover plate in which the skin and the base are directly integrated with a cushion layer made of a foam, it is necessary to prevent the foam from being exposed from the joint between the skin and the base to improve the appearance. With metal inserts, the substrate covered the exposed portion of the foam).

泡体の露出を防止するものが提案されている（実公昭62
−25958号公報又は実開昭58−111649号公報参照）。As one of the lids that prevent the exposure of such foam,
As shown in FIG. 4, a skin d having a bent portion c directed inward of the lid b is attached to the lower die a, and an outer peripheral portion g of the base body f attached to the upper die e and the bent portion c are attached. It has been proposed to prevent the foam from being exposed by joining the outer peripheral portion g and the bent portion c so as to oppose each other (Jitsuko Sho 62).
-25958 or Japanese Utility Model Laid-Open No. 58-111649).

当接させようとすると、表記ｄは下金型ａから剥離して
極端な場合には２点鎖線のように脱落するという問題点
を有していた。However, according to the conventional technique of the above proposal, as shown in FIG. 5, before the foaming of the foam h, the bent portion c of the flexible skin d is bent by its own weight, and the outer peripheral portion of the base body f is bent. There was a gap α between the g and the g. When the foam h is boiled from the bottom as shown by the arrow X, the foam h pushes up the bent portion c and joins it to the outer peripheral portion g of the base body f.
In the case of boiling up from the direction of arrow Y, the foam h has a problem that it leaks from the gap α between the upper and lower molds a and e. In this way, when the foam leaks out, the appearance of the foam becomes poor due to the exposure of the foam, and the defective rate of foaming such as voids and roughness due to lack of foam becomes high,
Pre-processing such as applying a mold release agent between the upper and lower molds becomes necessary. Therefore, as shown in FIG.
When the outer peripheral portion g of the above is projected downward and abutted against the bent portion c of the skin d, the notation d is separated from the lower mold a and in extreme cases falls off like a two-dot chain line. Had a point.
本発明は、従来の技術の有するこのような問題点に鑑み

なっている。According to the above configuration, when the cushion layer made of foam is formed between the flexible skin and the base body to form an automobile interior part, the slide die is provided on the contact surface of the base body with the tip of the step portion. Since the parts are pressed against each other, even if the thickness of the foam is increased, it is possible to reliably and easily prevent the foam from leaking between the flexible skin and the base body. As a result, the appearance is good and it is possible to prevent foaming failure due to leakage of the foam.

し易い。Then, in this molding method, a concave portion extending toward the center of the base body and a folded portion extending outward from the base body toward the center side of the base body are formed in advance on the outer periphery of the side surface portion of the flexible skin, and the folded metal mold is formed by a slide mold in the concave portion Since the folded portion of the recess is polymerized under pressure with the contact surface of the base body, even if the thickness of the foam is increased, the base body and the skin are reliably polymerized,
As a result, it is possible to reliably and easily prevent the foam from leaking. Further, the slide mold can be freely released from the inside of the recess, and when the mold is released, the slide mold is released from the inside of the recess so as not to interfere with the taking out of the automobile interior parts. In addition, it is easy to cut the folded portion.

Further, the outer circumference 7 of the base body 3 has a size within the side surface portion 5 of the skin 2 so as to be inconspicuous, and the outer circumference 7 of the base body 3 is
The lower surface is a contact surface 8 that faces the stepped portion 6 of the skin 2 and contacts the tip portion 9 thereof. Further, the tip 9 of the step 6 of the skin 2 is cut on the contact surface 8. And step 6
The contact surface 8 forms a recess 10. By disposing a mold or the like in the recess 10, it is possible to press the substrate 3 against the skin 2 to prevent the foam from leaking and maintain a predetermined shape. Further, since the contact surface 8 is hard, the extra skin 2 on the contact surface 8 can be cut by pressing a blade or the like, and the appearance is also clean.

ことができる。In the method of molding automobile interior parts, in the outer periphery of the side surface of the flexible skin, a concave portion extending toward the center of the base body and a folded portion extending outward from the base body are formed in advance, and a slide in the concave portion is performed. Since the mold is used to polymerize the folded surface of the concave portion with the contact surface of the base body under pressure, polymerization of the base body and the skin is ensured even if the thickness of the foam body is increased, and as a result, the foam body leaks. Can be reliably and easily prevented. Further, the slide mold is freely released from the inside of the recess, and when releasing the mold, it does not interfere with the removal of the automobile interior parts when released from the inside of the mold, and the folded part is easily cut. It is possible to reliably prevent the foam from leaking, save the pre-work such as applying the mold release agent between the upper and lower molds, and cut the extra bend to improve the appearance. You can get better.
