[0025] Please refer to Figures 1-4 The utility model provides a kind of technical solutions: a mold for laminated glass production, including lower mold 1 and the upper mold 14 being set above lower mold 1, lower mold 1 is provided with forming chamber 17, provides specific space for the forming of laminated glass;Forming chamber 17 is provided with flexible buffer pad 19 on bottom wall, flexible buffer pad 19 can uniformly exert pressure, effectively avoid bubble and wrinkle between glass and interlayer film, significantly improve the effect of bonding;

[0026] Specifically, the bottom wall of the forming chamber 17 is provided with a plurality of annular grooves 18 arranged in a matrix, and a through hole 181 is arranged at the center of the bottom wall of the annular groove 18 and is connected to the outside. The ejection assembly 2 is arranged on the lower mold 1, and the ejection assembly 2 includes a second cylinder 20 arranged below the lower mold 1. The distal end of the telescopic shaft of the second cylinder 20 is fixedly installed with a support plate 21. A plurality of guide columns 22 arranged in a matrix are fixedly installed on the upper surface of the support plate 21. The guide column 22 is located in the through hole 181 and is in sliding connection with the through hole 181. A rubber ejection disc 23 is detachably connected to the top end of the rod body of the guide column 22. The rubber ejection disc 23 is received in the annular groove 18, so that the second cylinder 20 can drive the guide column 22 to move up and down along the through hole 181 through the support plate 21 to eject the formed laminated glass from the forming chamber 17, thereby improving the convenience and efficiency of taking the sample.

[0027] In this embodiment, a center hard sleeve 24 is integrally formed at the center position of the rubber ejection disc 23. The center hard sleeve 24 is inserted and matched with a fastening screw 25. The fastening screw 25 is in threaded connection with the guide column 22. The center hard sleeve 24 is provided with a screw hole 242. The fastening screw 25 passes through the screw hole 242. The top hole wall of the screw hole 242 is provided with a receiving groove 241. The fastening screw 25 is hidden in the receiving groove 241, so that the normal fitting of the rubber ejection disc 23 on the bottom surface of the glass is not affected, and the ejection operation of the glass is not affected.

[0028] Specifically, the top surface of the center hard sleeve 24 is located below the top surface of the rubber ejection disc 23. The distance between the top surface of the center hard sleeve 24 and the top surface of the rubber ejection disc 23 is between 0.5cm and 1.2cm. The center hard sleeve 24 does not protrude from the top surface of the rubber ejection disc 23, which is beneficial to the normal ejection operation of the rubber ejection disc 23 on the glass.

[0029] Further, a plurality of support legs 10 are fixedly installed on the bottom surface of the lower mold 1. The support legs 10 are fixedly installed on the base outside, thereby providing a stable support basis for the entire mold. A support frame 11 is arranged above the lower mold 1. The top plate body of the support frame 11 is fixedly installed with two first cylinders 13 which are symmetrically arranged on the left and right sides. The upper mold 14 is arranged on the telescopic shaft of the two first cylinders 13, so that the first cylinder 13 can accurately control the up and down movement of the upper mold 14, thereby facilitating the opening and closing operation of the mold and improving the controllability and stability of the production process.

[0030] In addition, a fixed base 12 is fixedly installed at the bottom position of the left and right side plate bodies of the support frame 11. The fixed base 12 is fixedly installed on the base outside, thereby making the overall structure more firm and stable.

[0031] It is worth noting that a fixing plate 131 is fixedly installed at the end of the telescopic shaft of the first cylinder 13, and the upper mold 14 is fixedly installed on the bottom surface of the two fixing plates 131 by multiple fastening bolts, which facilitates the fixing and installation operation.

[0032] It is worth noting that both the upper mold 14 and the lower mold 1 are equipped with internal temperature control heating rods 15, which can accurately control the temperature inside the mold, ensure the uniformity of mold heating, and make the glass more evenly heated during hot pressing, thereby improving the bonding strength between the glass and the interlayer film and thus improving the product quality of laminated glass. A sealing groove 16 is provided on the upper surface of the lower mold 1, and a sealing gasket 161 is engaged in the sealing groove 16 to prevent air from entering the cavity during hot pressing, further ensuring the bonding quality between the glass and the interlayer film.

[0033] Finally, it should be noted that the second cylinder 20, the first cylinder 13, and the internal temperature-controlled heating rod 15 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0034] When using the mold for producing laminated glass of this utility model, the glass sheet to be processed and the intermediate film are first placed in the forming chamber 17 of the lower mold 1 in sequence, and the flexible buffer pad 19 can ensure that the placement is stable.

[0035] Subsequently, the first cylinder 13 is activated, and its telescopic shaft drives the fixed plate 131 and the upper mold 14 fixed on it to slowly descend and close with the lower mold 1, completing the mold closing and extrusion operation. At this time, the internal temperature control heating rod 15 starts to work, precisely controlling the internal temperature of the mold to ensure that the glass is heated evenly and promotes the tight bonding between the glass and the intermediate film.

[0036] After the hot pressing is completed, the first cylinder 13 works, and its telescopic shaft shortens to complete the mold opening operation. Then, the second cylinder 20 below the lower mold 1 is started, and its telescopic shaft pushes the support plate 21, which in turn drives the guide post 22 to rise in the through hole 181. The rubber ejector plate 23 connected to the top of the guide post 22 extends out from the annular groove 18, and smoothly ejects the formed laminated glass for easy removal.
