FIG. 5 is a sectional view taken along the line B-B in FIG. 1, and FIG. 6 is a cross-sectional view of an extruded product using the illustrated die. Each one has a slider,
The left and right side closing caps are fixed to the left and right extruded ends of the spreader, respectively, and a frame is attached to the upper and lower ends of the spreader. This is a case in which the 11-karat gold plate and slider on the right side can be moved, and a core for forming the hollow part is not provided.

右側面の形状が付グーされる。The material that is forced to be fed by the screw or piston of an extrusion molding machine is generally cylindrical, and after being deformed by a spreader into a shape similar to the cross-sectional shape of the extruded product, it is press-fitted into the mouthpiece. While the side closing cap prevents the substrate from escaping to the left and right, the two-part/lower cap gives the product its thickness and the shape of the top and bottom surfaces.
Next, the width of the product and the shape of the left and right sides are determined using the left and right ferrules.

の上面に押出方向の波状の変化を与えることができる。The number of upper and lower caps is not limited, and one each or two or more that can be slid against each other are used,
J: There is no problem even if the number of daily caps and lower caps are different. If there is only one two-part nozzle, the shape of the first edge of the cross section of the product will be constant, but by moving the nozzle up and down with the piston of the cylinder while the extruder is running, the top surface of the product A wave-like change in the extrusion direction can be applied to the extrusion direction.
上部口金が２倒置−１−の場合でも、その下面が同一平

させることができる。Even if the upper caps are 2 inverted - 1 -, if their bottom surfaces are on the same plane, they will work the same as one cap, but if the positions of their bottom surfaces are different, the shape of the top surface of the product will change accordingly. can be changed.
下部口金の作用も上部口金と同様である。The function of the lower cap is also similar to that of the upper cap.

If a slidable slider is also provided on the right side closing cap, the shape of the side surface of the product can be changed arbitrarily by moving the slider into and retreating from the base material. If sliders are also provided on the upper and lower caps, the shapes of the upper and lower surfaces of the product can be further changed.
