摘要： A mold assembly (10) for blow molding plastic articles (4) is provided having an upper mold member (12), a lower mold member (14) and a lower support member (16). The lower mold member (14) is preferably a relatively lightweight plate having a generally centrally located molding cavity (30) matingly matched with an upper molding cavity (20) in the upper mold member (12). The lower mold member (14) is moved horizontally and optionally vertically beneath an extrusion head (H) as a molten parison (P) is extruded. The lower mold member(14) is then transported to, and positioned within, the lower support member (16). The upper mold member (12) is then closed over the lower mold member (14) and lower support (16) to close the mold assembly (10). The molten parison (P) is then expanded in the mold cavity (20,30). After the molding operation, the plastic part (4) may be removed and the lower mold member (14) may be cooled by immersion in a cooling fluid. The apparatus to move the lower mold member (14) during extrusion of the parison (P) and to the molding station may be a robotic arm (R). The lower mold member (14) is relatively lightweight so that it may be efficiently moved by the robot arm (R) while the necessary structural support is provided by the lower support member (16).
摘要翻译：提供了一种用于吹塑塑料制品（4）的模具组件（10），其具有上模具构件（12），下模具构件（14）和下支撑构件（16）。下模具构件（14）优选地是相对轻质的板，其具有与上模具构件（12）中的上模制腔（20）配合配合的大致中心定位的模腔（30）。当挤出熔融型坯（P）时，下模具构件（14）水平地且任选地垂直地在挤压头（H）下方移动。然后，下模具构件（14）被运送到下支撑构件（16）并定位在下支撑构件（16）内。然后将上模具构件（12）封闭在下模具构件（14）和下支撑件（16）上以关闭模具组件（10）。熔融型坯（P）然后在模腔（20,30）中膨胀。在模制操作之后，可以去除塑料部分（4），并且可以通过浸入冷却流体来冷却下模具构件（14）。在型坯（P）挤出和模制站期间移动下模具构件（14）的装置可以是机器臂（R）。下模具构件（14）相对较轻，使得其可以被机械臂（R）有效地移动，同时由下支撑构件（16）提供必要的结构支撑。

摘要： A mold for use in blow molding has a first fixture (12) and a second fixture (14). The fixtures (12,14) correspond to typical mold halves or portions. The first fixture (12) includes drive means (40), typically in the form of pins (46), while the second mold fixture has drive receiving means (66), typically in the form of holes (70), to receive the pins (46). When the second mold fixture (14) is in registration with the first mold fixture (12), the pins(46) or other drive means (40) are extended to lock and locate the two fixtures (12,14) together. Blow molding can then be carried out without the need of the typical blow molding presses. A method of blow molding involves the use of a robotic arm (84) to move the relatively lightweight second mold fixture (14) described above beneath an extrusion head (102) to accept a parison as it is being extruded so the parison is contained within the mold cavity (60). After extrusion is complete the arm (84) moves the second fixture (14) toward the first fixture so that the fixtures (14) can be located and locked together. A single robot (110) using a single extrusion head (102) can serve several mold stations depending upon cycle times.
摘要翻译：用于吹塑的模具具有第一夹具（12）和第二夹具（14）。固定装置（12,14）对应于典型的半模或部分。第一夹具（12）包括通常为销（46）形式的驱动装置（40），而第二模具具有通常为孔（70）形式的驱动接收装置（66），以接收销（46）。当第二模具夹具（14）与第一模具夹具（12）对准时，销（46）或其他驱动装置（40）被延伸以锁定并将两个固定装置（12,14）定位在一起。然后可以进行吹塑，而不需要典型的吹塑机。吹塑成型的方法涉及使用机械手臂（84）将上述相对轻质的第二模具固定件（14）移动到挤出头（102）下方以接受型坯，因为它被挤压，因此型坯被包含在模腔（60）。在挤出完成之后，臂（84）使第二固定件（14）朝向第一固定件移动，使得夹具（14）能够被定位并锁定在一起。使用单个挤压头（102）的单个机器人（110）可以根据循环时间来服务于多个模具站。
