压铸模具以及借助伞形浇口制造空心塑料模制件的方法
摘要：
本发明涉及一种压铸模具(10)和一种方法用于制造由纤维增强塑料材料(2)构成的空心模制件(1)，该压铸模具(10)至少包括一个具有喷嘴(13、22)的第一模具半部(11)和一个具有至少一个型芯(14)的第二模具半部(12)。在型芯(14)和第一模具半部(11)之间构成可填充塑料材料的型腔(15)，该型腔通过伞形的浇道(3)与喷嘴(13、22)相连，该浇道具有球形区域(3a)。塑料材料借助喷嘴(13)通过伞形的浇道(3)在构成伞形浇口件(4)的情况下喷射到型腔(15)内，塑料材料(2)首先流过浇道(3)的球形区域(3a)并且接着进入型腔(15)中。
摘要（英）：

The invention relates to a die casting mould (10) and a method for producing hollow moulded part (1) made of fiber reinforced plastic material (2). The die casting mould (10) at least comprises a first die half portion (11) with nozzles (13,22) and a second die half portion (12) with at least a core (14). A cavity (15) which can be filled with the plastic material is formed between the core (14) and the first die half portion (11). The cavity is connected with the nozzles (13,22) through an umbrella-type pouring gate (3). The pouring gate is provided with a spherical region (3a). The plastic material is sprayed into the cavity (15) through the umbrella-type pouring gate (3) by the nozzles (13) under the condition that an umbrella-type sprue element (4) is formed. The plastic material (2) firstly flows through the spherical region (3a) of the pouring gate (3), and then enters the cavity (15).
