摘要： Metal alloy injection molding techniques are described. In one or more implementations, these techniques may also include adjustment of injection pressure, configuration of runners, and/or use of vacuum pressure, and so on to encourage flow of the metal alloy through a mold. Techniques are also described that utilize protrusions to counteract thermal expansion and subsequent contraction of the metal alloy upon cooling. Further, techniques are described in which a radius of edges of a feature is configured to encourage flow and reduce voids. A variety of other techniques are also described herein.

摘要： The invention relates to a device for controlling the advancing motion of a casting plunger in a casting chamber of a cold-chamber die casting machine by means of a control signal, wherein the advancing motion comprises a chamber filling motion segment from a partial filling position having a partially filled casting chamber starting volume to a full filling position having a filled casting chamber remaining volume. According to the invention, a respective associated curve of the control signal is provided in the device for different specified sets of values of a plurality of process parameters that influence the melt motion in the casting chamber during the chamber filling motion segment, which curve of the control signal is defined as the most suitable control-signal curve for the particular parameter value set, and the device is designed to use the most suitable control-signal curve to control the casting plunger advancing motion according to values of the process parameters present at the start of the casting cycle, wherein at least one casting chamber geometry parameter, at least one filling amount parameter, at least one casting shape parameter, and/or at least one casting chamber temperature or melt temperature parameter belongs to the plurality of process parameters. The invention further relates to the use thereof in the cold-chamber die casting technology.

摘要： A cold chamber die-casting machine for light alloys includes a sleeve (1) that fits into the base of a mold (2) and into the fixed platen (3) of a press, the position of the sleeve (1) being defined by a peripheral centering collar (4) that fits into a corresponding seat formed in the fixed platen (3) and/or in the base of the mold (2), as well as locking means suitable to make the sleeve (1) integral with the fixed platen (3) of the press, such as a ring (9) secured on the sleeve (1) by means of a thread, key or the like and arranged so as to abut against the external side (5) of the fixed platen (3). In this way, the injection and maintenance force is directly transmitted to the fixed platen (3) of the press and not to the mold (2), so as to prevent the risk of fall of the mold (2), to prevent the rotation of the sleeve (1) and to have the possibility of using the force of the press itself in case of difficult removal of the sleeve (1) from the mold (2).
摘要翻译：一种用于轻合金的冷室压铸机包括一个套筒（1），该套筒配合到模具（2）的底部和压机的固定台板（3）中，套筒（1）的位置由（3）和/或模具（2）的底部中形成的相应底座中的周边对中套环（4），以及适于使套管（1）与套管例如通过螺纹，钥匙等固定在套筒（1）上的环形件（9）的压机固定台板（3），并布置成抵靠固定台板的外侧（5）（3）。这样，注射和维持力直接传递到压机的固定台板（3）而不是模具（2），以防止模具（2）跌落的风险，防止旋转（1）上，并且在从模具（2）难以取出套筒（1）的情况下可以使用压力机自身的力。
