摘要：该设计方案首先分析了吹塑瓶的几何结构和瓶坯的吹塑成型工艺，模具的设计与工作时的温度控制等；然后提出了模具的设计方案，并阐述其工作原理。该模具结构设计合理，操作方便，能满足使用要求。模具主要由两个半阴模构成。因模颈圈与各夹坯块较易磨损，故一般做成单独的嵌块以便修复和更换。吹塑模具具有双重作用，赋予制品形状与尺寸，并使之冷却。吹塑模具可成型较复杂的制品，能有效的夹断型坯，保证制品接合缝的强度，能有效的排气，能快速均匀地冷却制品，并减小模具壁内的温度梯度，以减小成型时间与制品翘曲。该制件采用挤出吹塑，采用了流动阀来控制熔体的流动，使熔体轮换通过挤出机两侧的机头挤出型坯。合模、型坯的吹胀及制品的冷却与取走均在机头下方进行。由于设置多机头，故产量较高。33087

Abstract: The design analyzes the geometry and blow bottle preform blow molding process, temperature control, such as mold design and operation; and then made mold design, and explains how it works. The mold structure design, easy to operate, can meet the requirements. Mold is mainly composed of two half shade mode. Because mold collar with clip compact easier to wear, it is generally made of a single slug to repair and replacement. Blow mold has a dual role, giving the product shape and size, and allowed to cool. Blow molding mold can be more complex products, can effectively pinch off the parison, to ensure product bonding strength joints, can effectively exhaust can be rapid and uniform cooling products, and reduce the temperature gradient within the wall of the mold, to reduce small molding time and warpage. The article by extrusion blow molding, using a flow valve to control the flow of melt, melt extruder rotation through the nose on both sides of the extruded parison. Mold, cooling and removal of the parison blown and products in the bottom of the handpiece. Since the multi-head, so the higher yield.
