この考案は自動車用装飾モールに関し、特に詳

がある。 Synthetic resin is often used as a material for decorative moldings for automobiles. Compared to metal moldings, synthetic resin moldings have the advantage of being lightweight and allowing arbitrary selection of external shapes. A molding made of synthetic resin that has such advantages is adhered to the body of an automobile using double-sided tape attached to its bottom surface. Adhering the molding to the car body is done by pressing the molding against the car body, so if a hollow mold is used, the pressing force against the car body will be uneven, making it impossible to apply an even force to the entire area of the double-sided tape. Otherwise, parts with insufficient adhesion will be formed, causing the molding to peel off. For this reason, the molding made of synthetic resin is made into a solid body. On the other hand, in the case of large solid moldings, even if synthetic resin is used, the weight cannot be ignored, which goes against the trend of reducing the weight of car bodies, and improvements are desired. For this reason,
Attempts have been made to mold a large decorative molding with a hollow body and to attach the clip to the hollow molding. This method does not necessarily help in reducing the weight of the molding, and has the drawback that it requires many man-hours to install the reinforcing parts.
この考案によれば、装飾モールのための予備成
形物をブロー成形する際、クリツプを同時に止着
し、しかもクリツプの頭部まわりに予備成形物の
一部をまわしているので、クリツプがモールに確
実に固定され、クリツプ止着のための補強部品を
必要とせず、クリツプ止着の工数を大幅に減少さ
せ、装飾モールの軽量化が可能となる。 According to this invention, when blow molding a preform for a decorative molding, the clip is fastened at the same time and a part of the preform is wrapped around the head of the clip, so that the clip is attached to the molding. It is securely fixed, does not require any reinforcing parts for clip attachment, greatly reduces the number of man-hours required for clip attachment, and makes it possible to reduce the weight of the decorative molding.
それ故、この考案の目的は、装飾モールを中空
体として軽量化を図り、しかも、簡単に且つ確実
に止着されたクリツプを用いて自動車の車体への
固定を可能にさせている自動車用装飾モールを提
供することにある。 Therefore, the purpose of this invention is to reduce the weight of the decorative molding by making it hollow, and also to make it possible to fix it to the car body using clips that are easily and securely attached. The aim is to provide a mall.
この考案の実施例を添付図面を参照して説明す
る。 An embodiment of this invention will be described with reference to the accompanying drawings.
この考案による装飾モール１の断面を第１図に

リツプ３を本体２に確実に止着させる。 A cross section of a decorative molding 1 according to this invention is shown in FIG. The main body 2 is a hollow body, and the main body 2 is formed into a desired shape by blow molding a hollow preform (parison) made by extruding a thermoplastic resin in a mold. During this blow molding,
A portion of the preform wraps around the head 4 of the clip 3 held at a predetermined position in the mold, thereby firmly fixing the clip 3 to the main body 2.

の差込み部５の形状は、車体側のクリツプ受け部
形状に応じて適宜選択する。 An example of clip 3 is shown in FIG. Clip 3
has a rectangular head 4 from which an insert portion 5 extends integrally. The insertion portion 5 is formed so that the portion near the head 4 of the insertion portion 5 is recessed inward, bulges outward from the end of the recessed portion 6, and then becomes tapered. The recess 6 effectively surrounds the preform around the head 4 and ensures the fastening of the clip 3 to the molding body 2. Clip 3
The shape of the insertion portion 5 is appropriately selected depending on the shape of the clip receiving portion on the vehicle body side.

体の両端の加工も同時に成される。 FIG. 3 shows an example of the processing steps for the decorative molding 1 according to this invention. The thermoplastic resin material supplied from the hopper 7 is plasticized in the heated screw cylinder 8, and the plasticized resin is then accumulated in the accumulator 9. Next, the plasticized resin in the accumulator 9 is extruded by the ram 10 through the die 11 to form a hollow preform (parison) 12 of a predetermined length. The preform 12 is held between molds 13 holding the clips 3 inside, and after the molds are clamped, air is blown into the hollow preform 12 through the air nozzle 14 to inflate the preform 12.
It is shaped to fit the mold, and after cooling and solidifying, the mold is opened and the decorative molding 1 is taken out. During this blow molding, as shown in FIGS. 4 and 5, air is introduced into the preform 12.
Before being blown into the mold 13, the preform 12 is placed in the mold 13 along the outside of the head 4 of the clip 3 (the fourth
By blowing air, a portion of the preform 12 is wrapped around the recess 6 of the clip 3, so that the head 4 is surrounded by a portion of the preform 12. After cooling and solidifying, the clip 3 is reliably fixed to the molding body 2 by the body 2 around the head 4. Furthermore, both ends of the hollow body are simultaneously processed during blow molding.

Since the clip is fixed during blow molding of the decorative molding, the work for fixing the clip is easy.Moreover, since the molding body wraps around the head of the clip, the clip can be securely attached to the molding body. It can be fixed. In this way, it is possible to reduce the hollow weight of a particularly large decorative molding and to securely fix the vehicle body to the vehicle body.
