行われる。The screw incorporated in the extruder 1 is a single-screw type non-vented or vented or twin-screw type vent or non-vented, and its groove shape is either a full flight type or a dalmage shape, or a mixture of both types. good. The drive system of the extruding part to be plasticized is a hydraulic motor or an electric motor, and the rotation speed is changed or stopped by a control system by a microprocessor. The resin from the hopper 1b is plasticized at a predetermined temperature and sent to the measuring device 2. The meter 2 is configured to generate a signal for stopping the motor of the extruder by a sensor at a position when the resin melt flowing from the extruding section 1a reaches a predetermined volume in advance. When measured here, it is pushed out by the piston 5. At the entrance of the co-extrusion die 3, there is a shut valve, which is opened when the thermoplastic material is extruded from the measuring device 2, and prevents resin dripping from the co-extrusion die 3. I have. The resin that has passed through the shut valve is pattern-charged to the lower mold 1a of the pressure molding machine 11 by the table 4 which is operated two-dimensionally or three-dimensionally, while being extruded from the co-extrusion die 3 as a molten multilayer body. At that time, a cutter (not shown) for cutting off the sheet-like molten multilayer body is attached to the tip of the co-extrusion die 3, and is cut off last, and the upper mold 11b is lowered to perform press molding.

ーターである。In this apparatus, the extruder 1 and the measuring device 2 are integrated, and the integrated portion rotates the screw 7 when the thermoplastic resin is plasticized, as shown in detail in FIG. As a result, the measuring unit 8 corresponding to the measuring device 2 filled with the plasticized molten resin at the tip is formed. When the metering unit 8 reaches a certain capacity, the screw 7 stops rotating, advances as a piston, and is extruded as a molten multilayer body from the co-extrusion die 3, but the speed of the piston can be changed by numerical control. The program is programmed so as to be closely linked to the movement of the table 4 so that both the thickness configuration and the individual thickness of the product can be arbitrarily changed. Therefore, the thickness configuration of the material can be changed at any part of the multilayer molded article. In addition, 9 is a heater for heating.

圧縮成形される。In any of the above apparatuses, the extruder 1 is a table 4 of a mechanism driven by two-dimensional or three-dimensional numerical control.
It is placed and fixed on top. The tip of the cylinder has a feed block, which is a mechanism that combines the flows of the molten resin from two or more cylinders into a multilayer structure.
At the tip of the tip, a molten multilayer body is molded into a sheet using a T-die.
The pattern is charged on 11a according to the program by numerical control. Thereafter, when the table 4 is retracted and the co-extrusion die 3 is retracted from the mold, the upper mold 11b is lowered and compression molded.

On the skin side, a material having rubber properties is often used, such as ethylene propylene rubber, styrene butadiene rubber, and chloroprene rubber.

価格も大幅に安いものが使用出来る。The above-described method and apparatus are different from those in which a molten resin is injected from a gate like an injection molding method, and a molten multilayer body extruded from an extruder is charged on a pressure molding die,
Since it is sufficient to perform pressure molding, the molding pressure is about 1/3 of injection molding. Therefore, the material of the mold does not need to use expensive pressure-resistant material, the construction period is short,
The price can be much lower.

る。Further, in the multi-color molding by the conventional method, although it is possible to partially change the thickness of the constituent material by the mold design in two colors, it is almost impossible to change the thickness in three colors. With the multilayer molding method and apparatus described above, three-color molding can be easily performed.

を有する。As described above, in the present invention, since molding is performed using a multilayer molding machine, molding is integrally molded, so that not only the cost of molds and labor costs in products is significantly reduced, but also the laminating process is performed. This will greatly reduce the product failure rate and enhance the cost competitiveness of parts. Further, since the thickness configuration of the material can be arbitrarily and partially changed, the degree of freedom in combination is extremely large. Further, there is an advantage in that even small lots of many kinds can be profitable even in small lots with various changes without changing the manufacturing process of the product.
