[0001] The utility model relates to the technical field of plug - and - play connectors, and particularly relates to a quick plug - and - play connector for lost - foam production. Background Technique
[0002] Lost - foam casting (also known as full - mold casting) is a full - mold casting technology that uses a foam plastic mold with binder - free dry sand combined with a vacuum pumping technique. It is to bond and combine foam models similar in size and shape to the casting into a model cluster. After brushing and drying the refractory coating, it is vibrated and shaped in dry quartz sand, poured under negative pressure, so that the model gasifies, and the liquid metal occupies the position of the model, and a casting is formed after solidification and cooling. When producing the foam core, foam particles need to be injected into the mold through high - pressure gas.
[0003] Currently, the quick plug - and - play connectors for lost - foam production in the prior art usually plug the raw material conveying pipe into the insertion pipe on the mold. When in use, due to the need for quick plugging and unplugging, the raw material conveying pipe is plugged into the insertion pipe on the mold, but the plug - and - play connector cannot be stably connected. During transportation, the pipeline is prone to shaking, which causes the plug - in connector to become loose, and there is a problem that the plug - in structure cannot be stably connected. And when in use, after the plug - and - play connector is separated, the end of the plug - and - play connector needs to be placed on one side, and there is no protective structure on the outside of the plug - and - play connector, which is easy to damage the connector, and there is a problem of no protection for the connector.
