摘要： This relates to a blow molding machine of the type for blow molding large articles such as containers of the one gallon to five gallon size from a parison in the form of an extruded plastic material tube. The machine is of the rotary type and has a plurality of stations each carrying a mold unit of which one half is fixed and the other is mounted for radial movement between open and closed positions. The main shaft of the machine is of a large diameter and is tubular so that the necessary manifolding for gas and coolant supplies may be readily incorporated in the main shaft in an entirely different manner from that heretofore utilized. Also, among other features of the machine, is the provision of hollow spokes which serve not only to support outer mold halves for radial movement, but also serve as manifold accumulators for the necessary operating gases. There is also a new cushioning pad arrangement which holds the mold halves together under a light initial pressure facilitating the latching of the molds to a closed position with a minimum of camming force, after which the necessary pressure may be applied against the movable mold half so as to compensate for the opening pressures developed within the mold during the blow molding operation.

摘要翻译：本发明涉及一种吹塑机，该吹塑机用于从挤出塑料材料管形式的型坯吹塑诸如一加仑至五加仑大小的容器的大型制品。机器是旋转式的，并且具有多个工位，每个工位都装有一个模具单元，其中一个固定件，另一个安装成在打开和关闭位置之间径向移动。机器的主轴具有大直径并且是管状的，使得用于气体和冷却剂供应的必要的歧管可以以与迄今所使用的完全不同的方式容易地并入到主轴中。此外，机器的其它特征还包括提供中空轮辐，其不仅用于支撑用于径向运动的外半模，而且还用作必要操作气体的歧管蓄能器。还有一种新的缓冲垫装置，其在轻的初始压力下将模具半部分保持在一起，便于以最小的凸轮力将模具锁定到关闭位置，之后可以对可动模具半部施加必要的压力以补偿在吹塑操作期间在模具内产生的开启压力。

摘要： A vise clamp in which a movable jaw fits between and is slidable along a pair of guide rails of the vise base on surfaces normal to the clamping faces of the vise jaws and in which the novel movable jaw is tiltable to release and engage with a tension adjusting screw. The engaging surfaces on the movable jaw and the side rails are arranged to obtain force couples which hold the movable jaw in square position under load.
