摘要： The invention relates to a neck block of a mold for producing a hollow preform in an injection molding process. Said neck block comprises a base (10) with a shaping surface which is adapted to the outer contour of a neck section of the hollow preform that is to be produced and is to enter in contact with the neck section of the hollow preform during the injection molding process. At least one cooling duct (11) for a cooling fluid, at least some sections of which extend substantially parallel to the shaping surface, an inlet, an outlet, a supply duct and a discharge duct that connect the inlet or the outlet to the cooling duct are also provided, the cooling duct being disposed closer to the shaping surface than the inlet and the outlet. In order to create a neck block which is easy and thus inexpensive to produce while allowing for effective and homogeneous cooling especially in the vicinity of the shaping surface of the neck block, the cooling duct (11) encompasses at least one section that runs essentially parallel to the shaping surface and extends within the base (10) such that the walls of said section are formed by the base, and a connecting section (13) which adjoins said section and whose walls are formed in part by the base and in part by a closing element that is placed on the base.
摘要翻译：本发明涉及的模具的颈部块用于生产通过注射成型的中空体成型，所述颈部块具有一个成形面，其适于在中空本体成型的颈部的外轮廓和注射成型与所述中空体成型的颈部部分期间意的基体（10）接触了，进一步地，其中至少一个冷却通道（11）用于冷却流体，其中至少平行于所述成形表面部分基本上延伸，一个入口和一个出口和一个入口通道和出口通道，与所述入口和所述出口连接冷却通道，被设置，其中，所述冷却通道被布置成更靠近所述成形表面比所述入口和所述出口。为了提供一个颈部块，这是简单，因此制造成本低，并且在允许的颈部块的成形表面附近特别有效的和均匀的冷却，本发明提出的是，冷却通道（11）的至少一个基本平行于所述成形表面部分该内的基体（10）延伸，使得它的壁由基体形成的，和邻接该部分连接部（13），其壁并部分地被安装在所述基体闭合构件上部分地形成由主体，有。
