摘　　要：针对灭火器卡座塑件的特点,利用塑件上的开口及塑件自身的弹性强制脱模,将模具设计成带弹簧顶出活动型芯的两板式结构,模具制造简单,成本低,同时还介绍了模具成型工艺要求。In the case of injection moulding of plastic parts with lateral concave-convex characteristics, lateral core-pulling mechanism is usually used for the demoulding of parts. For a plastic clamping frame used in a fire extinguisher, a mould was designed based on the opening feature of the part and with use of forced spring demoulding instead of conventional lateral core-pulling mechanism for the ejection of movable cores and plastic component.
