Description

Technical Field

[0001] This utility model relates to the field of glass forming technology, and in particular to a glass hot bending machine. Background Technology

[0002] A glass hot bending machine is one type of glass forming equipment. It works by placing glass cut to a specified shape into a mold, then sequentially feeding the mold into a preheating station, a forming station, a slow cooling station, and a cooling station before finally demolding. At the forming station, the heated glass is shaped using the upper and lower molds.

[0003] Existing glass hot bending machines mainly consist of a sealed cavity and a heating station, a forming station for pressing and deforming the heated workpiece, and a cooling station for cooling the deformed workpiece. The cavity also includes a fork mechanism for transferring the product between the various stations. Because the glass requires multiple heating and cooling devices for gradual heating or cooling before and after forming, and these devices are arranged in a straight line, the overall length of such glass hot bending machines is large, requiring significant space and presenting significant challenges in on-site layout.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figures 1 to 4 As shown, the glass hot bending machine of this utility model includes a frame 12 and a cavity fixed to the top surface of the frame 12; the cavity is provided with a heating module, a forming module and a cooling module; the heating module, forming module and cooling module are arranged sequentially in the cavity; the heating module consists of multiple heating stations 3; the forming module consists of multiple forming stations 4; the cooling module includes multiple slow cooling stations 5; after the film mold 14 containing glass is fed into the heating module of the cavity, it is gradually conveyed towards the cooling module through a fork mechanism;

[0024] Heating station 3, forming station 4 and slow cooling station 5 are not fundamentally different from existing technologies, so they will not be discussed in detail.

[0025] Heating station 3 includes two heat spreaders positioned one above the other; the lower heat spreader supports the workpiece; there is a small gap between the heat spreaders of adjacent heating stations 3 to prevent heat leakage and to allow the mold to smoothly and stably cross the gap when the fork moves the mold; heat is transferred to the heat spreaders through external pipes, and then the lifting device on heating station 3 drives the upper heat spreader to press down onto the mold, thereby heating the workpiece; the heat spreaders have several pipes inside, and the pipes of the heat spreaders of each heating station 3 are independent, which makes it easy to set the heating temperature of each heating station;

[0026] Similarly, the slow cooling station 5 includes two heat spreaders arranged one above the other; heat is transferred to the heat spreaders through pipes, and then the lifting device on the heating station 3 drives the upper heat spreader to press down onto the mold, thereby heating the workpiece; the heat spreader has several pipes inside, and the pipes of the heat spreader of each heating station 3 are independent, which makes it easy to set the heating temperature of each heating station; the slow cooling station 5 includes two heat spreaders arranged one above the other, and then the lifting device on the slow cooling station 5 drives the upper heat spreader to press down onto the mold, and the cooling medium on the pipes absorbs and carries away the energy on the heat spreader, thereby cooling the workpiece;

[0027] The molding station 4 includes a support base located below, a pressure block located above, and a lifting device for driving the pressure block to move up and down; after the mold is transported to the support base, the lifting device drives the pressure block to press the mold into shape.

[0028] The cavity is U-shaped; the cavity consists of a forming chamber 2, an outer cooling chamber 7, and a cooling chamber 11; the two ends of the outer cooling chamber 7 are respectively connected to one end of the forming chamber 2 and one end of the cooling chamber 11; the heating station 3, the forming station 4, and the slow cooling station 5 are all located on the forming chamber 2; the outer cooling chamber 7 and the cooling chamber 11 are each provided with a water cooling station 6 near the end of the outer cooling chamber 7; the cooling chamber 11 is provided with a lower water cooling station 13;

[0029] The molding chamber 2, the external cooling chamber 7, and the cooling chamber 11 are all equipped with shift fork assemblies 8; these shift fork assemblies 8 are used for moving the mold.

[0030] Forming chamber 2, external cold chamber 7, and cooling chamber 11 are all box-shaped structures;

[0031] The structure of the water-cooling station 6 is the same as that of the slow-cooling station 5, but it is used to inject circulating cooling water into the heat spreader plate of the water-cooling station 6 through the pipes on the water-cooling station 6; the heat spreader plate is cooled by the circulating cooling water; the lower water-cooling station 13 is a heat spreader plate structure used to support the mold, which is connected to the cooling water to cool the lower mold; the temperature of the heat spreader plate on each heating station 3 gradually increases along the direction of the molding module; the temperature of the heat spreader plate on each slow-cooling station 5 gradually decreases along the direction away from the molding module; the temperature of the heat spreader plate on the water-cooling station gradually decreases along the direction away from the slow-cooling station 5.

[0032] The heating station 3, slow cooling station 5, water cooling station 6 and lower water cooling station 13 are arranged sequentially in the "U"-shaped cavity formed by the forming chamber 2, the outer cooling chamber 7 and the cooling chamber 11, which shortens the overall length of the equipment and reduces the difficulty of the equipment's spatial layout.

[0033] In a preferred embodiment of this utility model, a mold displacement mechanism 9 is provided on the frame 12; the mold displacement mechanism 9 is located at the end of the cooling chamber 11 away from the outer cooling chamber 7; the mold displacement mechanism 9 includes a rotating component 902, a linear module 903, and a guide groove 904 fixed on the frame 12; one end of the linear module 903 is fixed on the frame 12; the other end of the linear module 903 is fixed on one end of the rotating component 902; a rotating shaft 901 is fixed to the other end of the rotating component 902; a push plate 905 is fixed to the end of the rotating shaft 901;

[0034] The linear module 903 is not fundamentally different from the existing technology, so it will not be described in detail. A push mold structure 10 is provided at the end of the cooling chamber 11 to push the mold at the end of the cooling chamber 11 into the guide groove 904. The linear module 903 drives the rotating component 902, the rotating shaft 901 and the push plate 905 to move to the rear of the mold 14. Then the rotating component 902 drives the rotating shaft 901 and the push plate 905 to move, so that one end of the push plate 905 is aligned with the mold 14. Then the linear module 903 will make the rotating component 902, the rotating shaft 901 and the push plate 905 move in a straight line together, transporting the mold 14 away from the outer cooling chamber 7 to the set position, which is convenient for the subsequent picking and placing of the mold 14.

[0035] In a preferred embodiment of this utility model, the rotating component 902 is a rotary cylinder.

[0036] In a preferred embodiment of this utility model, the molding chamber 2 is provided with a demolding mechanism 1 at the end away from the external cold chamber 7; the demolding mechanism 1 includes a clamping assembly 101, a translation module 102, and a lifting module 103; one end of the translation module 102 is fixed to the frame 12; the other end of the translation module 102 is fixed to one end of the lifting module 103; the clamping assembly 101 is fixed to the other end of the lifting module 103;

[0037] The translation module 102 and the lifting module 103 are not fundamentally different from the existing technology, so they will not be described in detail. The clamping component 101 is not fundamentally different from the existing clamping structure. The clamping component 101 consists of two grippers and a cylinder that drives the two grippers to move away from or towards each other. The cylinder causes the two grippers to move, thereby achieving the clamping and loosening of the upper mold.

[0038] Before the mold 14 enters the molding chamber 2, the upper mold needs to be opened and the lens to be molded needs to be placed in. The translation module 102 and the lifting module 103 move together to drive the clamping component 101 to move. The clamping component 101 is used to clamp and fix the upper mold of the mold 14.

[0039] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
