It is something.

１．０〜１．５ Ｋ（］／ｍである。(Prior Art) A conventional manufacturing method for this type of base material will be explained. First, the main raw materials are pulp raw materials such as wood pulp and paper pulp, and various fibers such as hemp fiber, 1ti cotton fiber, and chemical fiber.
A mixture of phenolic resin is used as a binder. This raw material is then subjected to baking or needling treatment to achieve a tensile strength of 2. OKgf/width s
The mat has handling properties of Oam or higher. In this case, the specific gravity of the mat is 0.1 to 0.3, and the basis weight is 1.0 to 1.5 K(]/m.

材として取出される。Next, the mat manufactured as described above is transferred to the reinforcing material insertion step shown in FIG. In the reinforcing material insertion process, the above-mentioned mats 21 and 21 are first placed on the lower die 20. Then, the reinforcing material 23 is set on the mat 21 so as to fit the four parts 22 formed on the molding surface of the lower mold 20. Furthermore, mat 2 is placed on top of that again.
1, the upper die 24 is lowered under this condition, and the upper mold 24 is pressed under predetermined conditions. FIGS. 5(a) to 5(C) show the progress during clamping. That is, the reinforcing material 23 enters into the four parts 22 as the upper die 24 descends, and is enveloped by both the upper and lower mats 21,21. After the pressing is completed, the binder is cured to give a specific gravity of 07 to 1.1. Fabric weight: 2.0 to 3.0 K (1/7

雑であった。(Problems to be Solved by the Invention) As described above, the conventional method for manufacturing the base material is a method in which the reinforcing material 23 is sandwiched between two mats and pressed. In other words,
Prior to the reinforcing material insertion process, a handling process was required to impart handling properties to both mats 21 and 21. For this reason, in the past, a process that merely imparted handling properties was unavoidable, so there was room for reduction in the number of man-hours. In addition, it was necessary to set the reinforcing material in a state in which it was sandwiched, which made the work complicated.
そこで、本発明は工数の削減並びに作業の簡略化が図れ
る基材製造方法を提供することを目的としたのである。Therefore, an object of the present invention is to provide a method for manufacturing a base material that can reduce the number of man-hours and simplify the work.

み込んだ状態で成形させることとしたのである。(Means for Achieving the Object) In order to achieve the above object, the present invention uses a fleece-like raw material made of pulp or fiber as the main raw material and a thermoplastic binder added thereto, and molds at least one of them. Prior to closing the upper and lower clamping molds having concave portions on their faces, the fleece-like raw material is introduced between the two molds, and the fleece-like raw material is reinforced so that it can fit into the four parts and is almost buried in the fleece-like raw material. By setting the material and then closing the mold, the reinforcing material was wrapped in the fleece-like raw material and molded.

る。(Function) When the mold is closed with the reinforcing material embedded in the fleece-like material, the fleece-like material gradually covers and envelops the reinforcing material. Then, by press molding, a base material is taken out in which the fibers are linked together by the binder and the bending rigidity is increased by the reinforcing material.

短い程よい。(1) Raw materials The raw materials used in this example are mainly pulp or fibrous materials, to which a binder made of a thermosetting resin material is added in a predetermined ratio. Specifically, wood pulp or paper pulp is used as the pulp, and hemp fiber, cotton fiber, or chemical fiber is used as the fiber, either singly or as a composite. Further, as a binder, phenol resin, urea melamine resin, etc. are used, and the amount added is about 10 to 30% in terms of weight/absorption ratio. The raw material thus formed must exhibit appropriate fluidity in the fleece state, that is, it must be put into the molds 1 and 2 and matted as described below. The fiber must have a low tensile strength in a fleece mat state, and the shorter the fiber length, the better.

First, to explain the structure of the equipment used in this process, in the same figure, 1 and 2 are a pair of upper and lower molding molds, and on the molding surface on the lower mold 2 side, over a predetermined length range,
A recess 3 with a channel-shaped cross section is formed, which is compatible with a reinforcement 4. On the other hand, a reinforcement set pin 5 is attached to the upper die 1 at a position directly above the recess 3. This set pin 5 is assembled via a sleeve 6, and is connected to a reciprocating mechanism (not shown) to a retracted position where its tip is almost flush with the molding surface of the upper mold 1 (see FIG. 1(b). ) to (d)) and a working position protruding from the molding surface by a predetermined amount (see (a) in the same figure). Further, although not shown in detail, the set pin 5 has a suction means (for example, a means using a magnet or air suction) for the reinforcing material 4 attached to its tip.

フリース状原Ｆ３１Ｆがこぼれ出ないようにしている。The periphery of the molding surface of the lower mold 2 is surrounded by a side wall (not shown), which prevents the fleece material F31F poured into the lower mold 2 from spilling out.

２０℃にまで加熱しておく。First, insert the set pin 5 approximately 20 to 40 mm from the molding surface of the upper mold 1.
A reinforcing material 4 made of a metal square pipe or the like is adsorbed to the tip of the reinforcing material 4 and held along the longitudinal direction of the recess 3. In this case, the molding molds 1 and 2 are 180 to 2
Heat to 20℃.

てなされる。Next, the fleece-like raw material F is put into the lower mold 2. In this case, the fleece-like raw material F is introduced to a depth where the entire reinforcing material 4 can be buried. The input raw material F is different from the conventional one,
Since handling property is not imparted, that is, the material is not matted, the material is introduced by means such as suction.

At an appropriate time, the set pin 5 is returned to the sleeve 6 and is kept on standby in a state substantially flush with the molding surface. When the upper die 1 is further lowered, the reinforcing material 4 is gradually wrapped up by the fluidity of the fleece material F itself (the first
(See figure (b)). As the upper mold 1 further descends, the reinforcing material 4 is almost completely enveloped as shown in FIG.
Pushed inside. In this example, the press pressure at this time is 20 to 30 Klll/cIi.

。Thus, after the predetermined molding time has elapsed, the binder in the raw material F hardens, so that the rigid base material K is taken out after the mold is opened. In addition, a skin material 7 is attached to the base material thus obtained in a post-process to form an automotive package tray trim P (see FIGS. 2 and 3).

Additionally, the manufacturing process for the base material has been extremely simplified, as once the reinforcing material has been set, the fleece material is simply placed between the molds.
