Further, the mold 40 is attached to the extruder 1, and the mold 40 extrudes a molded product S including a pair of left and right molded portions 41, 41 and a connecting portion 42 connecting the molded portions 41, 41 to each other. Since the connecting portion 42 of the molded product S is automatically cut in the longitudinal direction, the component (molded portion) 4 is formed.
You can get 1,41 two at a time.

In the above-described example, the cutting blade 3 is provided so as to be movable in the width direction of the transport path 2. In addition, the cutting blade 3 is provided so as to be movable in the longitudinal direction of the transport path 2. Is also good. With this configuration, even when the extrusion of the molded product S is stopped, the molded product S is moved in the longitudinal direction of the transport path 2 while the cutting blade 3 is protruded from the transport path 2. It can be cut in its longitudinal direction. In the above example, the mold 40 is used to extrude and mold a molded product S including a pair of left and right molded portions 41, 41 of the same shape and size, and a connecting portion 42 connecting these molded portions 41, 41. However, the present invention is not limited to this, and a molded product having a different shape, a different size, and a connecting portion connecting these formed portions may be extruded by another mold, The number of formed portions is not limited to two, but may be three or more.
