US08501059B2 Injection unit having a filter, a method of controlling melt pressure in accordance with a target pressure range 失效
具有过滤器的注射单元，根据目标压力范围控制熔体压力的方法

Injection unit having a filter, a method of controlling melt pressure in accordance with a target pressure range
Abstract:
There is provided a method (300) of controlling melt pressure at a filter outlet (113) of a melt filter (112) in an injection unit (100) having an extruder (102) that is connectable to a melt accumulator (122) via the melt filter (112), the melt filter (112) being associated with a target melt pressure range, the method executable at a controller (126) associated with the injection unit (100), the method (300) comprising: appreciating (310) an indication of an actual melt pressure associated with the melt filter (112); responsive to the actual melt pressure not being within the target melt pressure range, determining (320) a remedial parameter that is instrumental in bringing the actual melt pressure within the target melt pressure range; releasing (330) a control signal to execute an action associated with the remedial parameter, thereby causing the actual melt pressure to fall within the target melt pressure range.
Abstract(Chinese):

提供了一种在具有挤出机（102）的注射单元（100）中的熔体过滤器（112）的过滤器出口（113）处的熔体压力控制方法（300），挤出机（102）可连接到熔体储存器（122） 所述熔体过滤器（112），所述熔体过滤器（112）与目标熔体压力范围相关联，所述方法可在与所述注射单元（100）相关联的控制器（126）处执行，所述方法（300）包括： ）与熔融过滤器（112）相关联的实际熔体压力的指示; 响应于不在目标熔体压力范围内的实际熔体压力，确定（320）有助于使实际熔体压力达到目标熔体压力范围内的补救参数; 释放（330）控制信号以执行与补救参数相关联的动作，从而使实际熔体压力落入目标熔体压力范围内。
