    Abstract: The present invention discloses an apparatus for producing a pressure vessel blank (2) comprising at least one connection element (7), the apparatus having the following features: - the apparatus comprises a multi-part blow-moulding tool with at least two blow-mould halves (10), which in each case have a partial cavity (11) and between which a tubular preform (9) consisting of thermoplastic material can be positioned in an open position of the blow-mould halves (10); - the blow-mould halves (10) can be made to move between an open position, in which the blow-mould halves (10) are apart from one another, and a closed position, in which the blow-mould halves (10) are in contact with one another, the partial cavities (11) forming in the closed position a mould impression in which the preform (9) can be moulded to form the pressure vessel blank (2) by means of applying differential pressure; - the apparatus comprises at least one blowing pin (20), which has a gas outlet opening (22), arranged in an end portion (21) of the blowing pin (20), for discharging a gas and a holding device (26) for releasably holding the connection element (7), the end portion (21) of the blowing pin (20) being insertable into a through-passage (7a) of the connection element (7); and - the blowing pin (20) can be positioned between the blow-mould halves (10), so that in the closed position of the blow-mould halves (10) the preform (9) positioned between them can be moulded in the mould impression while being brought to bear against the connection element (7) by application of gas pressure by way of the gas outlet opening (22). The apparatus is characterized in that the blowing pin (20) has a fluid outlet (23), arranged in the end portion (21), for discharging a cooling fluid and a fluid inlet (24), arranged in the end portion (21), for receiving the cooling fluid, and in that the fluid outlet (23) and the fluid inlet (24) are in fluidic connection with one another, so that the through- passage (7a) of a connection element (7) held by the blowing pin (20) can be brought directly into contact with the cooling fluid and a cooling fluid circulation can be produced in the through-passage (7a) of the connection element (7).

    Abstract translation: 本发明公开了一种用于生产包括至少一个连接元件(7)的压力容器坯件(2)的设备,该设备具有以下特征: - 该设备包括具有至少两个吹塑成型工具的多部件吹塑工具, 半模(10),其在每种情况下具有部分空腔(11),并且其间由热塑性材料组成的管状预成型件(9)可以位于吹塑半模(10)的打开位置; - 吹塑半模(10)可以在吹塑半模(10)彼此分开的打开位置和关闭位置之间移动,在该位置中吹塑半模(10) 彼此接触,部分空腔(11)在关闭位置形成模具印模,其中预成型件(9)可以通过施加差压成型而形成压力容器坯料(2); - 所述装置包括至少一个吹塑销(20),其具有布置在所述吹塑销(20)的端部(21)中的用于排放气体和保持装置(26)的气体出口(22) 为了可释放地保持连接元件(7),吹塑销(20)的端部(21)可插入连接元件(7)的通道(7a)中; 并且 - 吹塑销(20)可以位于吹塑半模(10)之间,使得在吹塑半模(10)的关闭位置,位于它们之间的预成型件(9)可以模制在模具 同时通过气体出口(22)施加气体压力而使连接元件(7)承受压力。 该装置的特征在于,吹风销(20)具有布置在端部(21)中的用于排出冷却流体的流体出口(23)和布置在端部(21)中的流体入口(24) ,用于接收冷却流体,并且流体出口(23)和流体入口(24)彼此流体连接,使得连接元件(7)的通过通道(7a)由 吹塑销(20)可以直接与冷却流体接触,并且可以在连接元件(7)的通路(7a)中产生冷却液循环。
