Glass hot bending property detection method and mold thereof

The invention discloses a glass hot bending property detection method and a mold thereof, glass is placed in a preset mold, the mold is divided into an upper mold and a lower mold, a balancing weight with required weight is placed on the top of the upper mold of the mold, and certain pressure is applied to the glass through the weight of the balancing weight to promote the glass to better fit the shape of the mold; putting the mold with the balancing weight and the glass into an annealing furnace, heating the annealing furnace to a preset temperature corresponding to the type of the glass, and keeping the temperature for a period of time after the preset temperature is reached, so that the glass is repeatedly and uniformly heated; taking out the glass in the mold, observing and recording the hot bending condition of the glass, and preliminarily judging the hot bending performance of the glass according to the appearance and form of the glass; if the proper bending angle does not appear, the glass is not suita
