Description

Technical Field

[0001] This utility model relates to the field of precision glass molding equipment, specifically to a rapid heating and cooling device for a glass molding machine. Background Technology

[0002] This utility model relates to the field of precision glass molding equipment. Since most glass molding equipment integrates the heating and cooling platforms into one unit on the heating module, it is difficult to achieve rapid heating and cooling of the mold, and the required energy consumption and time costs are high. Therefore, the rapid heating and cooling device used in this glass molding machine provides a new heating and cooling method for the future development of faster and more energy-efficient molding equipment.

[0003] Existing heating devices stack multiple layers into one, and the heating effect is affected by the cooling layers while heating the mold. After the mold is formed and heating is stopped for cooling, the heating device also needs to be cooled simultaneously before the mold can be cooled down. Therefore, such heating devices are not only inefficient but also energy-intensive. This invention takes into account the space limitations and sealing requirements of molding equipment. By designing a hot and cold exchange component, a hot and cold ejection component, and a hot and cold lateral movement component, the heating mold and cooling mold are separated into two parts. The heating and cooling modules are interchanged through external movement, which improves the production efficiency of glass molding and reduces the energy consumption of heating and cooling products. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid heating and cooling device for glass molding equipment, so as to solve the problems of low heating and cooling efficiency and high energy consumption in existing equipment.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: A rapid heating and cooling device for glass molding equipment is provided, comprising:

[0006] The machine base plate and the machine front plate together form the machine frame;

[0007] The mold frame assembly is installed above the machine base plate;

[0008] The heat exchange component is installed inside the mold frame component;

[0009] The hot and cold ejection assembly is installed below the base plate of the machine;

[0011] The lifting linear bearing is installed below the machine base plate;

[0012] The transverse linear bearing and the transverse wire harness outlet linear bearing are installed on the front plate of the machine.

[0013] Furthermore, the mold frame assembly consists of a platform base, positioning pressure block, positioning pressure plate, positioning block, positioning pin, heat spreader plate, 1 / 4-10 pipe connector, connecting water pipe I, connecting water pipe II, and linear guide rail. The positioning pressure block, positioning pressure plate, positioning block, positioning pin, and heat spreader plate are installed on the platform base. The 1 / 4-10 pipe connector is installed on the side of the platform base. Connecting water pipe I and connecting water pipe II are connected to the 1 / 4-10 pipe connector. The linear guide rail is installed inside the platform base. The heat spreader plate is installed on the platform base as a carrier for heating the mold and is pressed down by the positioning pressure plate.

[0014] Furthermore, the heat exchange assembly comprises a cooling block, a heating block, a heat-conducting block I, a heat-conducting block II, a heating block cooling plate, a cooling bend I, a cooling bend II, a cooling water pipe I, a cooling water pipe II, a heating rod, a bundled pipe, a connecting water pipe, an ejector connecting plate, a pipe 1 / 2-12 connector, and a pipe 12-12 connector. The cooling block and the heating block cooling plate are mounted on the ejector connecting plate. The heating block, heat-conducting block I, and heat-conducting block II are stacked on the heating block cooling plate from top to bottom. Cooling water pipe I and cooling water pipe II connect the heating block cooling plate and the cooling block. The ends of cooling water pipe I and cooling water pipe II are connected to pipe 12-12 connectors. The connecting water pipe and the bundled pipe are installed on the left side of the cooling block. Cooling bend I and cooling bend II are respectively installed on the left and right sides of the heating block cooling plate through pipe 1 / 2-12 connectors. The heating rod is installed inside the heating block.

[0015] Furthermore, the hot and cold ejection assembly comprises a servo motor, a long lifting linear bearing, a motor mounting plate, a guide shaft, a lifting plate, a lifting connector, a spring, a push rod, and a lifting fixing plate. The servo motor and the long lifting linear bearing are mounted on the motor mounting plate. The guide shaft passes through the long lifting linear bearing and connects to the lifting plate. The lifting connector is mounted on the servo motor and connects to the lifting plate, driving its up and down movement. The push rod passes through the spring and connects to the lifting plate. The lifting fixing plate is fixed to the motor mounting plate.

[0016] Furthermore, the aforementioned hot and cold lateral motion assembly comprises a pipe clamp, a pull block mounting plate, a rodless cylinder, and a cylinder mounting plate. The pipe clamp is mounted on the pull block mounting plate, the pull block mounting plate is mounted on the rodless cylinder, the rodless cylinder is mounted on the cylinder mounting plate, and the cylinder mounting plate is mounted on the front plate of the machine.

[0017] Compared with the prior art, the beneficial effects of the rapid heating and cooling device for glass molding equipment provided by this utility model are as follows: When using the rapid heating and cooling device for glass molding equipment provided by this utility model, the mold is placed on the heat exchange plate. At this time, the heating plate of the heat exchange component is located below the heat exchange plate. Driven by the servo motor, the lifting joint drives the lifting plate upward, which drives the lifting rod upward. The lifting rod pushes the heating block cooling plate upward, thereby causing the heating block of the heating module to stick tightly to the heat exchange plate and transfer heat to the heat exchange plate, thereby heating the mold for a period of time. When a certain temperature is reached, the glass is molded and formed and maintained at a certain temperature for a period of time. After the glass lens is formed and pressure is maintained, cooling is required. At this time, the servo motor drives downward, causing the heating block to separate from the heat exchange plate. After the heating module descends, the rodless cylinder of the hot and cold horizontal motion assembly moves the pull block mounting plate, causing the tube clamps on top to hold the bundled tubes. This moves the entire hot and cold exchange assembly to the left via the linear guide rail of the mold frame assembly, positioning the cooling block below the heat spreader. Then, driven by a servo motor, the lifting joint moves the lifting plate upward, which in turn moves the lifting rod. The lifting rod pushes the cooling block upward, ensuring it is in close contact with the heat spreader. The water-cooled circulation structure of the cooling block removes heat from the heat spreader and the mold, causing its temperature to drop and completing the molding process. Therefore, this process reduces the heat generated during heating and cooling, improving production efficiency and reducing energy consumption.

[0029] Example 1: A rapid heating and cooling device for glass molding equipment

[0030] Please see Figure 1 and Figure 2When the mold containing the glass raw material is heated and cooled, the mold is initially placed on the heat exchange plate 8. At this time, the heating block 17 of the heat exchange component is located below the heat exchange plate 8. Driven by the servo motor 35, the lifting joint 40 drives the lifting plate 39 upward to drive the lifting rod 42. The lifting rod 42 pushes the heating block cooling plate 30 upward, thereby causing the heating block 17 of the heating module to be tightly attached to the heat exchange plate 8, transferring heat to the heat exchange plate 8, thereby heating the mold. When a certain temperature is reached, the glass becomes molten and needs to be molded and kept at a certain temperature for a period of time. After the glass lens is molded and pressure is maintained, it needs to be cooled. At this time, the servo motor 35 drives downward to separate the heating block 17 from the heat exchange plate 8. After the heating module descends, the rodless cylinder 33 of the hot and cold transverse motion component moves to drive the pull block mounting plate 32, causing the bundle tube 26 clamped by the tube clamp 31 to move the entire hot and cold exchange component to the left through the linear guide rail of the mold frame component, so that the cooling block 16 is located below the heat spreader plate 8. Then, driven by the servo motor 35, the lifting joint 40 drives the lifting plate 39 to move upward and drive the lifting rod 42. The lifting rod 42 pushes the cooling block 16 upward so that it is tightly attached to the heat spreader plate 8. The water cooling circulation structure inside the cooling block 16 carries away the heat from the heat spreader plate and the mold, causing its temperature to drop, and the molding is completed.

[0031] Please see Figure 3 , Figure 4 and Figure 5 As a further explanation of the heat exchange component of the rapid heating and cooling device for glass molding equipment provided by this utility model, when heating or cooling the mold, cooling water enters from cooling water pipe II 24, passes through cooling block 16, then enters cooling block 16 again through connecting water pipe 27, and exits from cooling water pipe II 24 at the other end, thus performing a cold circulation for cooling block 16. Similarly, cooling water passes through cooling water pipe I 23, through the holes in cooling block 16, and enters heating block cooling plate 20. After entering, it flows out from cooling bend II 22, re-enters heating block cooling plate 20, and exits from cooling water pipe I 23 at the other end, thus performing a cold circulation for heating block cooling plate 20. The circuit lines of heating rod 25 and its sensor enter the bundle tube 26 and are then led out.

[0032] Please see Figure 3 , Figure 6 , Figure 7As a further explanation of the hot and cold ejection assembly and the hot and cold transverse movement assembly in the rapid heating and cooling device for glass molding equipment provided by this utility model, when the mold needs to be heated and cooled, the heating block 17 and the cooling block 16 need to be tightly attached to the heat spreader plate 8. Therefore, the hot and cold ejection assembly needs to move. Driven by the servo motor 35, the lifting joint 40 drives the lifting plate 39 to drive the lifting rod 42 up or down, thereby making the heating block 17 and the cooling block 16 tightly attached or disconnected. For the switching of the hot and cold exchange assembly, when not tightly attached, the rodless cylinder 33 drives the tube clamp 31 on the pull block mounting plate 32. The tube clamp 31 drives the bundle tube 26 to make the hot and cold exchange assembly move on the linear guide rail 15.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
