[0021] The mold clamping conveyor of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] As shown in the figure, the mold closing conveyor of the present invention includes a frame 1, an inlet conveyor belt 2 arranged in the frame and connected with an external conveying device, and a transition conveyor belt 3 located directly behind the inlet conveyor belt. The external conveying device is used to convey a material holding frame 4 with a mold placed on it to the inlet conveyor belt 2. The inlet conveyor belt 2 can convey the material holding frame 4 with a mold placed on it to the transition conveyor belt 3. A manipulator 5 for grabbing the upper lens mold and the lower lens mold in the material holding frame is arranged above the end of the transition conveyor belt 3. In this embodiment, the upper lens mold is a concave mold, and the lower lens mold is a convex mold. After the concave mold and the convex mold are matched, a complete casting mold is formed. Specifically, a grabbing arm 8 for grabbing the upper lens mold and the lower lens mold is arranged on the manipulator. A suction cup for adsorbing the concave mold and the convex mold is arranged at the end of the grabbing arm 8. The suction cup of the grabbing arm 8 is used to adsorb on the convex mold and the concave mold. On the non-forming surface, the grabbing arm 8 absorbs and grabs the die and the punch through the suction cup, and the manipulator 5 places the grabbed mold at the entrance of the mold clamping machine through two grabbing arms. The entrance of the mold clamping machine is provided with an upper mold conveyor belt 10 for conveying the die and a lower mold conveyor belt 11 for conveying the punch. After the grabbing arm 8 grabs the die, the die can be placed on the upper mold conveyor belt 10, and after the grabbing arm 8 grabs the punch, the punch can be placed on the lower mold conveyor belt 11; a lifting drive device 6 capable of driving the transition conveyor belt to rise and fall is provided below the transition conveyor belt 3, and the lifting drive device 6 is preferably a cylinder or an oil cylinder, and an outlet conveyor belt 7 is provided below the inlet conveyor belt 2. After the die and the punch are grabbed by the manipulator, the lifting drive device 6 can drive the transition conveyor belt to descend so that the transition conveyor belt can transport the material holding frame that completes the conveying of the die and the punch to the outlet conveyor belt 7.

[0023] Furthermore, the transition conveyor belt 3 is installed on the lifting frame 19, and the lifting drive device 6 is installed in cooperation with the lifting frame 19 and can drive the lifting frame to move up and down. Moreover, there are three suction cups of the grabbing arm 8, that is: the three suction cups of the grabbing arm 8 are a group. Of course, the inlet conveyor belt 2, the transition conveyor belt 3 and the outlet conveyor belt 7 are also designed to be corresponding to the number of the three suction cups of the grabbing arm 8. Finally, there are three transition conveyor belts 3 as a group of three suction cups of the upper grabbing arm 8 corresponding to the grabbing arm 8, thereby three concave dies or punches can be grabbed at one time, further improving the production efficiency.

[0024] Furthermore, the suction cup on the grabbing arm 8 can be parallel to the upper mold conveyor belt 10 after adsorbing the concave mold, so that the concave mold is placed horizontally on the upper mold conveyor belt 10; thereby, the molding surface of the concave mold faces downward, and the grabbing arm 8 can be rotated so that the suction cup and the lower mold conveyor belt 11 have an inclined angle, and the lower mold conveyor belt 11 is provided with a guide ramp 12. After the grabbing arm 8 grabs the lower lens mold, it is rotated to an angle suitable for the guide ramp 12 and then placed on the guide ramp 12. Specifically, the suction cup on the grabbing arm 8 swings to the lower mold conveyor belt 11 after adsorbing the non-molding surface of the punch, and then places it on the guide ramp 12 from below the guide ramp 12, thereby making the molding surface of the punch face upward, Figure 5 It can be seen that the guide inclined plate 12 has a preset space for the grabbing arm 8 to pass through, and the preset space can be a slot, through which the punch can be smoothly placed on the guide inclined plate 12. Due to the action of the guide inclined plate, the punch can slide onto the lower die conveyor belt 11. Of course, in order to ensure the reliability of the placement of the punch, a stopper located at the end of the guide inclined plate 12 can also be provided on one side of the lower die conveyor belt 11. In addition, the guide inclined plate 12 is fixedly mounted on a movable plate 14 driven by a guide drive device 13. The guide drive device 13 is preferably a cylinder. The guide inclined plate 12 can be driven by the movable plate 14 under the drive of the guide drive device 13. The plate 14 drives the movement and enables the punch to fall smoothly on the lower mold conveyor belt 11. The upper mold conveyor belt 10 is arranged in parallel with the lower mold conveyor belt 11. The upper mold conveyor belt 10 is located on the outside of the lower mold conveyor belt 11 and is higher than the lower mold conveyor belt 11. In addition, an upper shifting block 16 driven by an upper shifting drive device 15 is provided at the end of the upper mold conveyor belt 10. After the upper mold is transported to the end of the upper mold conveyor belt 10, it can be shifted to the mold clamping machine through the upper shifting block. The end of the lower mold conveyor belt 11 is provided with a lower shifting block 18 driven by a lower shifting drive device 17. After the lower mold is transported to the end of the lower mold conveyor belt 11, it can be shifted to the mold clamping machine through the upper shifting block.
