In order to solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: a forming mold for hot bending glass, comprising an upper mold and a lower mold, and a connecting shaft is rotatably connected at the top of one side of the lower mold, and the connecting shaft is on the connecting shaft. A clamping slot is provided, a clamping head is connected on one side of the bottom of the upper die, a forming slot is arranged on the top of the lower die, an ejection slot is opened at the bottom of the lower mould, and the lower die is in the ejection slot. The bottom of both sides is connected with an ejector mechanism, and the center of the upper mold is provided with a feeding hole.

Further, the clip head is clipped in the clip slot.

Further, the ejection mechanism includes two sets of hydraulic cylinders, and hydraulic rods are slidably connected in the hydraulic cylinders, and two sets of the hydraulic rods are connected to one end of the hydraulic cylinder and are jointly connected with a top plate, and the top plate is placed on the ejector. in the slot.

Further, a plug is provided on the side of the upper mold close to the lower mold to be connected with the ejection groove.

Further, a handle is connected to one end of the upper mold away from the chuck.

Further, a hydraulic pump is provided on one side of the lower mold in conjunction with the ejection mechanism.

Compared with the prior art, the utility model has the advantages that the structure of the utility model is simple, and by arranging the clamping head and the connecting shaft, the flexible connection between the upper mold and the lower mold can be realized, and the speed and efficiency of the mold clamping are improved; The hydraulic pump drives the ejection mechanism, which can realize the rapid removal of the product, which is beneficial to reduce the damage of the product due to improper manual removal operation, and has strong practicability.
