縮して接着していた。(Prior art) For example, among the organic friction materials currently manufactured, vapor-based friction materials are produced by impregnating a sheet-shaped friction base material with a thermosetting resin binder and then drying it once it hardens. An adhesive was then applied to one side of the sheet, dried again, punched into a predetermined shape, and adhered to a friction material support such as a core plate by heating and compression.

I/A is performed by compression molding and adhesion in a mold using means such as heat compression on a friction material support such as a core plate coated with adhesive.

問題があった。(Issue m to be solved by the invention) After vapor-based friction materials are punched into a predetermined shape, the friction base material is wasted. Furthermore, in so-called wet friction materials used in lubricating oil, it is necessary to form grooves for oil drainage, but methods have been attempted in which paper-based friction materials are pressure-formed during adhesion. However, compared to grooving during machining, there are disadvantages in that the groove depth varies and the groove shape becomes non-uniform. Furthermore, since the curing of the friction base material and the adhesion to the friction material support such as the core plate are performed in different steps, the steps are complicated and the reliability of the product is low.

良く生産できなかった。With rubber kneading materials, the above-mentioned problems such as groove forming are eliminated because the molding is done in a mold, so there are no problems such as variations in depth or non-uniform groove shapes. It required a process of molding and punching the sheet into a predetermined shape, making it difficult to produce efficiently.

体的な形状を成形するという手段を用いる。(Means for Solving the Problems) In order to achieve the object, the present invention uses injection molding or injection compression molding, which has not been used conventionally in molding friction materials, to mold organic friction materials. At the same time, adhesion is performed on a friction material support such as a core plate, and a three-dimensional shape such as an oil groove is formed.

Further, for surface step processing, a steel material that has been subjected to step processing in advance is punched into a desired shape, or after processing such as punching, machining to form a step is performed to obtain the friction material support 12.

り出す。Injection molding or injection molding is carried out using a normal commercially available vertical injection molding machine.The friction support shown in Figure 3 is placed in a predetermined position using an automatic machine in a previously opened mold. The mold is closed and the organic friction material is injected. The organic friction material is kneaded and heated in advance in the cylinder 22 in the injection molding machine to be sufficiently fluidized, and at the same time as injection, it flows into the spool 24 inside the mold through the cylinder nozzle port 23 and finally reach inside the cavity. When the inside of the cavity is sufficiently filled, injection is interrupted and the cylinder 22 is retreated from the cylinder nozzle port 23. After heating and hardening the organic friction material for several minutes, the molds 20 and 21 are opened and the friction plate shown in FIG. 1 is taken out using an automatic machine or the like.
