発泡により表皮の位置がずれ易く、しばしば表皮が正規
の位置からずれた表皮一体発泡成形品となることがあっ
た。It is almost impossible to install the device in close contact with the cavity surface. Therefore, the position of the skin tends to shift due to the injection of the foaming raw material and the foaming of the foaming raw material, often resulting in a skin-integrated foam molded product in which the skin is shifted from its normal position.
この発明は、前記従来技術の問題、即ち発泡原料の注入
発泡中に表皮が成形型の所定位置からずれ易い問題を解
決し、表皮の位置ずれのない表皮一体発泡成形品を製造
する方法を提供するものである。The present invention solves the problem of the prior art, that is, the skin tends to shift from the predetermined position of the mold during injection and foaming of foaming raw materials, and provides a method for producing a skin-integrated foam molded product in which the skin does not shift. It is something to do.
〈問題点を解決するための手段）
この発明は、発泡型に装置した表皮内に発泡原料を注入

の注入発泡中、発泡型の所定位置に設けた真空吸引孔に
より表皮を吸引して型内面に表皮を密着固定させること
を特徴とするものである。<Means for Solving the Problems> The present invention provides a method for producing a skin-integrated foam molded product in which a foaming raw material is injected into the skin installed in a foaming mold. The feature is that the epidermis is suctioned through the provided vacuum suction hole to tightly fix the epidermis to the inner surface of the mold.
（作用）
この発明により表皮一体発泡成形品を製造するには、次
のようにして行う。(Function) A skin-integrated foam molded product according to the present invention is manufactured as follows.
まず、所定位置に真空吸引孔を設けた発泡型に表皮を装
置し、その表皮を真空吸引孔により吸引して型内面に密
着固定させる。First, a skin is placed on a foaming mold provided with vacuum suction holes at predetermined positions, and the skin is suctioned through the vacuum suction hole to tightly fix the skin to the inner surface of the mold.
次いで、表皮を型内面に真空吸引した状態で表皮内に発
泡原料を注入し、発泡型を閉じて発泡原料を発泡させる
。その際表皮が真空吸引されて型内面に密着固定されて
いるため、表皮の位置ずれを生じることなく発泡する。Next, the foaming material is injected into the skin while the skin is vacuum-suctioned to the inner surface of the mold, and the foaming mold is closed to foam the foaming material. At this time, the skin is vacuum-suctioned and tightly fixed to the inner surface of the mold, so foaming occurs without any displacement of the skin.
そして、発泡原料の発泡によって、表皮と接着し一体と
なった発泡体が形成される。Then, by foaming the foaming raw material, a foamed body that is bonded and integrated with the skin is formed.
その後、成形品を脱型すれば所望の表皮一体発泡成形品
を得る。Thereafter, the molded product is demolded to obtain a desired skin-integrated foam molded product.
得られた表皮一体発泡成形品は、表皮が所定の位置で発
泡体と一体となったものであり、所期の外観及び品質か
らなるものである。The obtained skin-integrated foam molded product has the skin integrated with the foam at a predetermined position, and has the desired appearance and quality.
（実施例） 以下実施例に基づいてこの発明を説明する。(Example) The present invention will be explained below based on Examples.
第１図はこの発明の一実施例に関するもので、インスト
ルメントパネル用発泡型の下型１０に表皮を装置した状
態を示す。FIG. 1 relates to an embodiment of the present invention, and shows a state in which a skin is attached to a lower mold 10 of a foam mold for an instrument panel.
この発泡型は、下型１０と上型（図示せず）からなり、
製品形状の型内面からなるキャビティ１２を有し、かつ
型内面には型外の真空ポンプ１６に連通ずる真空吸引孔

型内面の凹形状部位に設けるのが好ましい。この発泡型
を用いて次のようにして表皮一体発泡成形品を製造する
。This foaming mold consists of a lower mold 10 and an upper mold (not shown),
It has a cavity 12 formed from the inner surface of the mold in the shape of a product, and the inner surface of the mold has a vacuum suction hole 14 that communicates with a vacuum pump 16 outside the mold. The vacuum suction hole 14 is connected to the epidermis 18.
In order to be able to suction and adhere tightly to the inner surface of the mold without any gaps,
It is preferable to provide it in a concave portion of the inner surface of the mold. Using this foam mold, a skin-integrated foam molded product is manufactured in the following manner.
まずこの発泡型の下型１０型内面に表皮１８を載置し、
真空吸引孔１４から表皮１８と型内面間の空気を真空吸

皮を発泡型に装置する。表皮１８は、真空吸引可能な材
質、例えばプラスチックレザー等からなるものとする。First, the skin 18 is placed on the inner surface of the lower mold 10 of this foam mold,
The air between the skin 18 and the inner surface of the mold is vacuum-suctioned through the vacuum suction hole 14 to bring the skin 18 into close contact with a predetermined position on the inside of the mold, thereby forming the skin into a foamed mold. The skin 18 is made of a vacuum suctionable material, such as plastic leather.
更に必要に応じてインサートをキャビティ１２内に装置
する。Furthermore, an insert is installed in the cavity 12 as required.
次いで表皮１８内にポリウレタンフォーム原料等の発泡

中所定の位置からずれることなく型内面に密着固定する
ことができる。表皮内に注入した発泡原料は、発泡して
表皮内を埋め、表皮と接着して一体となった発泡体を形
成する。Next, a foaming raw material such as a polyurethane foam raw material is injected into the skin 18, the foaming mold is closed by the upper mold, and the foaming raw material is foamed. During this time, the skin 18 is continuously vacuum-suctioned onto the inner surface of the mold. Thereby, the skin 13 can be closely fixed to the inner surface of the mold without shifting from a predetermined position during the injection and foaming time. The foaming material injected into the epidermis foams to fill the epidermis and adheres to the epidermis to form an integrated foam.
その後真空吸引を止め、成形品を発泡型から取り出せば
、所望の表皮一体発泡成形品を得ることができる。Thereafter, by stopping the vacuum suction and removing the molded product from the foaming mold, a desired skin-integrated foamed molded product can be obtained.
このようにして得られる表皮一体発泡成形品は、発泡原
料の注入、発泡時表皮を型内面に真空吸引密着させるも
のであるから、表皮の位置ずれかないものとなり、所期
の外観及び品質を有するものとなる。The skin-integrated foam molded product obtained in this way has the desired appearance and quality because the skin does not shift in position because the foaming raw material is injected and the skin is brought into close contact with the inner surface of the mold by vacuum suction during foaming. Become something.
