摘要： The disclosed method of controlling a pressurizing pin, which serves to replenish for the necessary locality with molten metal during solidification of molten metal charged in the cavity, features that the operation of the molten metal replenishment by the pressurizing pin is caused when it is detected that the volume of non-solidified metal has become less than the volume effective for obtaining a molten metal replenishment effect. It is thus possible to obtain efficient replenishment for the necessary locality with molten metal by using a pressurizing pin which is limited in size and stroke.
摘要翻译：所公开的控制加压销的方法，其用于在填充在空腔中的熔融金属固化期间用熔融金属补充必要的位置，其特征在于当检测到加压销的熔融金属补给时，非固化金属的体积已经变得小于获得熔融金属补充效果的有效量。因此，可以通过使用限制尺寸和行程的加压销来获得对熔融金属的必要部位的有效补充。

摘要： A pressure casting method is disclosed, which permits sufficient pressurizing effect to be obtained for the entire molten metal by varying the speed of advancement of a pressurizing pin according to the state of solidification of the molten metal during pressurizing. In pressure casting using a pressure casting apparatus, while charged molten metal is solidified, it is pressurized by causing advancement of the pressurizing pin into a cavity of the die. During this time, the reaction force received by the pressurizing pin from the molten metal is measured by a pressure sensor, and the speed of advancement of the pressurizing pin is varied through control of the opening degree of a flow control valve according to the measured reaction force. While the reaction force during the progress of solidification of molten metal is high, the flow control valve is controlled to a high opening degree to provide for a high speed of advancement of the pressurizing pin so as to apply a high pressurizing force. On the other hand, while the reaction force is low so that there is a delay in the solidification of molten metal, the speed of advancement is reduced so that no pressurizing force is applied until completion of solidification of molten metal. The pressurizing pin is advanced while its advancement speed is controlled in the above way, and pressurizing over the entire stroke is completed.
摘要翻译：公开了一种压铸法，其通过根据加压期间的熔融金属的凝固状态改变加压销的前进速度，从而对整个熔融金属获得足够的加压效果。在使用压力铸造装置的压力铸造中，当充入的熔融金属固化时，通过使加压销进入模具的空腔而被加压。在此期间，通过压力传感器测量加压销从熔融金属接收的反作用力，并且通过根据所测量的反应来控制流量控制阀的开度来改变加压销的前进速度力。当熔融金属凝固进行期间的反作用力高时，流量控制阀被控制到高开度，以提供加压销的高速推进以施加高的加压力。另一方面，当反作用力低时，熔融金属的凝固延迟，提前速度降低，直到熔融金属凝固完成之前不施加加压力。加压销前进，其进给速度以上述方式控制，并且整个行程的加压完成。

摘要： A method for coating a die surface with a foamed release agent is disclosed. The release agent is foamed outside a die and then is supplied to a die cavity. Alternatively, liquid release agent is supplied to the die cavity and then is foamed inside the die. Excess foamed release agent is removed from the die before molten metal is supplied to the cavity. Alternatively, the foamed release agent is left in the cavity, and molten metal is supplied to the cavity. The release agent is foamed through mechanical agitation, bubbling, or by gas released from the release agent when heated.

摘要： A parting agent capable of being applied to a die with split die members closed, and preventing the production of defective castings and the occurrence of heat shock as well as the precipitation of a solid lubricant. The parting agent is composed of a mixture of a parting component, a dispersing component for dispersing the paritng component through water, a surface active agent as a foaming agent, and water, and is foamed into a foamy state. The foamy parting agent can be applied to the die with the split die members closed. This overcomes problems caused by the scattering of the parting agent due to spraying. In addition, since the parting component is retained with a film defining foam, the separation and precipitation thereof can be prevented.
摘要翻译：能够将分模模具用于模具的脱模剂封闭，防止有缺陷的铸件的产生和热冲击的发生以及固体润滑剂的析出。脱模剂由分离成分，通过水分散分散成分的分散成分，作为发泡剂的表面活性剂和水的混合物组成，发泡成发泡状态。泡沫分离剂可以在分开的模具构件关闭的情况下应用于模具。这克服了由喷涂引起的分离剂飞散所引起的问题。此外，由于分离成分被保留有限定泡沫的膜，因此可以防止其分离和沉淀。
