Abstract: An injection mold apparatus has multiple injection zones, each zone having at least one heater and at least one temperature sensor generating a temperature indicating signal. A power source provides power to the heaters. A controller controls the temperature of at least some of the zones. For efficiency, the controller has two separate processors, a data-receiving processor for receiving temperature indicating signal from each sensor as well as power signals, and a control processor for receiving data from the data-receiving processor and for controlling the amount of power provided to the heaters. Preferably, the control is in a housing, with the housing mounted directly on the mold. Modified PID calculations are utilized. Power calculations for the amount of power to the heaters utilizes a modulo based algorithm.

Abstract: An injection mold apparatus for the injection molding of plastic articles. The mold apparatus has a plurality of take-off plates. Each of the take-off plates comprises a plurality of article acceptors. The take-off plates are movable between positions wherein the article acceptors can accept molded articles from the mold and positions wherein the molded articles are moved away from the mold. In a preferred embodiment, each of the article acceptors consists of opposed half-cylinders which can be separated to accept and discharge the molded articles. Also in preferred embodiments, each of the article acceptors is internally cooled so as to be able to cool each article acceptor after it has been moved away from the mold.

Abstract: A hot tip nozzle assembly for injection molding plastic components comprises a nozzle housing defining a hot runner passage and a nozzle tip section which is received in the hot runner passage. The nozzle tip section defines a hot runner tip passage in flow communication with the hot runner passage. The nozzle tip section slides freely within the hot runner passage during injection molding. A stop is provided on the nozzle tip section to limit downward movement relative to the cavity gate and automatically position the nozzle tip relative to the injection gate of the mold. In addition, axial thermal expansion of the nozzle housing is not imparted to the nozzle tip section. The nozzle tip section also has a restricted length that can axially thermally expand. Accordingly, the position of the nozzle tip is only minutely affected by even larger temperature changes in the nozzle assembly. This controlled thermal expansion together with the sliding movement of the nozzle tip section relative to the nozzle housing maintains the nozzle tip at a substantially constant position during the injection molding operation and minimizes vestige formation in the molded components.

Abstract translation: 用于注射塑料部件的热尖嘴组件包括限定热流道通道的喷嘴壳体和容纳在热流道通道中的喷嘴尖端部分。 喷嘴尖端部分限定了与热流道通道流动连通的热流道尖端通道。 在注射成型期间，喷嘴尖端部分在热流道通道内自由滑动。 在喷嘴末端部分设有一个止动件，以限制相对于腔体浇口的向下移动，并相对于模具的注射口自动定位喷嘴尖端。 此外，喷嘴壳体的轴向热膨胀不会赋予喷嘴头部。 喷嘴尖端部分也具有可以轴向热膨胀的有限长度。 因此，喷嘴头的位置仅受喷嘴组件中的甚至更大的温度变化的微小的影响。 这种受控的热膨胀以及喷嘴头部分相对于喷嘴壳体的滑动运动在注射成型操作期间将喷嘴头保持在基本上恒定的位置，并且最小化模制部件中的痕迹形成。
