挤压成型装置以及热塑性弹性体成型品的制造方法
摘要：
本发明提供挤压成型装置以及热塑性弹性体成型品的制造方法，该挤压成型装置，即便使用因摩擦而易产生变形的热塑性弹性体材料也能获得较高的尺寸精度。配置在对热塑性弹性体(10)加热并将其挤出的挤压机(2)与抽取热塑性弹性体(10)的抽取机(3)之间的形状调整机(4)，具有充满有冷却水(W)的水槽(40)。在划分出水槽(40)的侧壁(42)设置有：由用于供热塑性弹性体(10)进入到水槽(40)内的贯通孔形成的入口(45a)、和由用于供热塑性弹性体(10)从水槽(40)排出的贯通孔形成的出口(45b)。入口(45a)的口径大于从挤压机(2)挤出后即将进入入口之前的热塑性弹性体(10)的外径，冷却水(W)的水位高于入口(45a)及出口(45b)的上端。
摘要（英）：

The invention provides an extrusion forming device and a manufacturing method of a thermoplastic elastomer formed piece. The extrusion forming device can obtain higher size precision even using extrusion forming devices which are easy to deform because of friction. A shape adjuster (4) configured between an extruder (2) for heating and extruding a thermoplastic elastomer (10) and an extracting machine (3) of the thermoplastic elastomer (10) is provided with a water tank (40) filled with cooling water (W). A sidewall (42) dividing a water outlet tank (40) is provided with an inlet (45a) formed by a through hole allowing the thermoplastic elastomer (10) to enter the water tank (40), and an outlet (45b) formed by a through hole for discharging the thermoplastic elastomer (10) from the water tank (40). The caliber of the inlet(45a) is greater than the external diameter of the thermoplastic elastomer (10) which is extruded by the extruder (2) and is going to enter the inlet; a water level of the cooling water (W) is higher than upper ends of the inlet (45a) and the outlet (45b).
