Door closure subassembly and pressure vessel overcoat mould

The utility model aims at providing a door closure subassembly and pressure vessel overcoat mould. The utility model provides a door closure subassembly is installed on the portal, including lid and lid positioning mechanism. Lid positioning mechanism can change the distance between lid and the portal to when making the lid stretch into the mould staving following the portal motion, can be fixed aposition in the position of difference in the mould staving, thereby formed the enclosure space of different length, and then formed the pressure vessel overcoat of different specification length. The utility model provides a pressure vessel overcoat mould, including above -mentioned door closure subassembly to can be used for producing the pressure vessel overcoat of different specification length. 本实用新型的目的是提供种门盖组件及压力容器外套模具。本实用新型提供的门盖组件，安装在门架上，包括盖体和盖体定位机构。盖体定位机构能够改变盖体与门架之间的距离，从而使盖体在跟随门架运动而伸入模具桶体时，能够在模具桶体内被定位在不同的位置，从而形成不同长度的封闭空间，进而形成不同规格长度的压力容器外套。本实用新型提供的压力容器外套模具，包括上述门盖组件，从而能够用来生产不同规格长度的压力容器外套。
