[0038] Basic usage of casting machine with safety anti-fall mechanism:

[0039] The casting machine is generally a differential pressure casting machine or a low pressure casting machine, which generally includes the following processes: preliminary preparation, liquid raising, mold filling, pressure holding crystallization, pressure relief cooling, mold opening and part removal, etc. The focus of this application is on the safety issues during mold separation and mold opening and part removal in the preliminary preparation.

[0040] When the mold needs to be opened, the upper mold is very heavy and there may be a risk of accidental falling. When the mold is opened, the mold-closing cylinder pulls up the upper mold until the upper mold and the lower mold are completely separated. At this time, the swing drive source drives the support rod to swing and is located between the upper mold and the lower mold. When the mold needs to be closed, the support rod swings back to its position, and the mold-closing cylinder drives the upper mold downward until the mold is closed. During the swinging process of the support rod, its position is detected by the travel switch, and the color of the indicator light changes to remind workers or robots whether they can enter, ensuring the safety and convenience of the entire device.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
