Description

Technical Field

[0001] This invention relates to the field of bottom mold alternating cooling technology, specifically to a bottom mold alternating cooling device for high-temperature glass forming. Background Technology

[0002] High-temperature glass is a special type of glass that can reach or withstand corresponding temperatures and pressure levels under certain temperature, medium, and pressure conditions. It is generally made from high-purity silica mineral materials through high-temperature refining. It can maintain the original transparency and clarity of glass even in high-temperature environments. High-temperature glass has the characteristics of high transparency, high temperature resistance, good thermal stability, and stable chemical properties. It is an indispensable key component of industrial automated production lines and is widely used in industries such as pressure vessel manufacturing, steel, metallurgy, petrochemicals, and lighting. In the process of high-temperature glass processing, in order to shape the high-temperature glass, a base mold body is needed to form the high-temperature glass into a predetermined shape. The base mold body is one of the important base mold bodies used to support and shape the glass. The high-temperature glass carrying high temperature is poured onto the base mold body, and the high-temperature glass can quickly take shape according to the shape of the base mold body. The temperature carried by the high-temperature glass will be transferred to the base mold body. In order to facilitate the continuous use of the base mold body, it is necessary to cool it down in a timely manner.

[0003] Therefore, we have made improvements to this by proposing a bottom mold alternating cooling device for high-temperature glass forming. Summary of the Invention

[0004] The purpose of this invention is to provide a bottom mold alternating cooling device for high-temperature glass forming, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The device includes a cooling pool with a cooling coil inside. An observation window is pre-sealed in the middle of the outer side of the cooling pool. Inlet and outlet pipes are symmetrically arranged above and below the observation window on the outer side of the cooling pool. Both the inlet and outlet pipes are connected to the cooling pool and are used to transport coolant, which is pure water. A ring pipe is fixedly installed on the top of the cooling pool, and a top plate is fixedly installed on the top of the ring pipe. A bottom mold body is fitted at the center of the top plate. A replacement assembly is pre-set in the inner cavity of the ring pipe. The replacement assembly includes a central disk pre-set at the center of the inner cavity of the ring pipe, and copper disks are arranged in a rectangular array on the outer side of the central disk. The top of a group of copper disks is in contact with the bottom mold body.

[0006] As a preferred technical solution of this application, the outer rectangular array of the central disk has an extension tube, the interior of the central disk has a central groove extending to one end, and the inner side of the central disk has a connecting groove about the rectangular array of the central groove, and the connecting groove connects the interior of the central groove and the extension tube.

[0007] As a preferred technical solution of this application, one end of the central disk is provided with an inwardly recessed first locking groove in a rectangular array. The central disk is fitted with a cylinder through the first locking groove. The inner side of the central disk is provided with a movable groove. The first locking groove is connected to the connecting groove through the movable groove.

[0008] As a preferred technical solution of this application, a pressure plate is fixedly installed at the output end of the cylinder. The pressure plate is circular. The central disk is sleeved with the pressure plate through a movable groove. Mounting disks are installed on the inner side of the four sets of cylinders. A first motor is snapped onto the end of the mounting disk away from the central disk. A first mounting shaft is symmetrically installed on the outer side of the first motor. The first motor is located on the outer side of the cylinder and there is a gap between it and the cylinder to provide space for the rotation of the cylinder. The first mounting shaft is connected to the inner side of the ring tube.

[0009] As a preferred technical solution of this application, a second motor is preset at one end of the central disk opposite to the first motor, and a second mounting shaft is symmetrically mounted on the outer side of the second motor, and the second mounting shaft is fixedly connected to the outer side of the central disk.

[0010] As a preferred technical solution of this application, the central disk is rotatably sleeved with a winding shaft through a central groove, and a second snap-fit ​​groove extending inward is opened at one end of the winding shaft located outside the central disk. The winding shaft is snapped with the output end of the second motor through the second snap-fit ​​groove.

[0011] As a preferred technical solution of this application, a partition is fixedly installed on the outer side of the winding shaft, and a first pull rope and a second pull rope are wound on the outer side of the winding shaft at intervals. There are two sets of the first pull rope and the second pull rope, which are vertically distributed. The first pull rope and the second pull rope are located at both ends of the partition, and the two sets of the first pull rope and the two sets of the second pull rope extend through the four sets of connecting grooves to the inner side of the extension tube.

[0012] As a preferred technical solution of this application, the extension tube is internally rotatably fitted with a telescopic shaft, the bottom of the four sets of telescopic shafts are respectively connected to the first pull rope and the second pull rope, the top of the telescopic shaft is fixedly connected to the outer side of the copper disc, and a return spring is sleeved on the outer side of the telescopic shaft. The two ends of the return spring are respectively connected to the inner side of the copper disc and the outer side of the central disc.

[0013] As a preferred technical solution of this application, heat dissipation fins are symmetrically installed on the inner side of the ring tube, and side plates are fixedly installed on the inner side of the two sets of heat dissipation fins. The side plates are heat-conducting plates, and absorbent cotton is fixedly installed on the inner side of one set of side plates. The size of the absorbent cotton is larger than the size of the copper plate.

[0014] As a preferred technical solution of this application, the top of the cooling pool is provided with a top groove, which matches the copper plate. The copper plate extends through the top groove into the inner cavity of the cooling pool and dissipates heat through the coolant. The two ends of the cooling coil are respectively equipped with an inlet pipe and an outlet pipe. The inlet pipe and the outlet pipe extend through the side wall of the cooling pool to its outer side. The inlet pipe and the outlet pipe facilitate the delivery of fluorine coolant into the interior of the cooling coil.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Through a rotating assembly consisting of a central disc, a first motor, a second motor, a winding shaft, a pull rope, and a cylinder, multiple copper discs can be automatically and cyclically switched between two states: contacting the bottom mold body to absorb heat and immersing in the cooling pool to dissipate heat. This allows the heat-absorbing part of the bottom mold body to be quickly removed and cooled, while the cooled part can be immediately replenished to the working position. This overcomes the bottleneck of long waiting time for cooling of a single bottom mold body in traditional methods, and greatly improves the continuity of high-temperature glass forming operations and overall production efficiency.

[0016] 2. By using a cylinder-driven pressure plate to selectively squeeze and lock a specific first or second pull rope, combined with the second motor to control the winding shaft, independent lifting and lowering control of one or more specific copper discs can be achieved; thus, based on the heat distribution or cooling requirements in actual production, targeted cooling can be carried out on local overheated areas, or the rotation rhythm can be flexibly adjusted, realizing the customization and precision of the cooling strategy.

[0017] 3. The copper disc is directly immersed in a cooling pool filled with pure water coolant and exchanges heat efficiently with the internal coiled cooling coils, forming a dual-enhanced cooling system. Secondly, by controlling the reciprocating up and down movement of the copper disc in the cooling pool, the coolant in the pool is actively agitated, breaking down temperature stratification, promoting fluid flow and heat convection, so that heat can be carried away more quickly and evenly, avoiding local boiling or cooling dead zones.

[0018] 4. After the copper plate is raised from the cooling pool and before it contacts the bottom mold body, its outer surface will be covered with specially designed absorbent cotton. The absorbent cotton can effectively absorb and remove residual coolant carried on the surface of the copper plate, ensuring that the copper plate contacts the bottom mold body in a dry and clean state, thus avoiding the adverse effects that residual coolant may have on the high-temperature glass forming process.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention provides a technical solution: such as Figure 1 - Figure 10 A high-temperature glass forming bottom mold alternating cooling device is shown, including a cooling pool 1. The inner cavity of the cooling pool 1 is provided with a cooling coil 2. The middle of the outer side of the cooling pool 1 is sealed with an observation window 5. The outer side of the cooling pool 1 is symmetrically arranged with an inlet pipe 3 and an outlet pipe 4 about the observation window 5. The inlet pipe 3 and the outlet pipe 4 are both connected to the cooling pool 1. The inlet pipe 3 and the outlet pipe 4 are used to transport coolant. The coolant is pure water. The top of the cooling pool 1 is fixedly installed with a ring pipe 7, and the top of the ring pipe 7 is fixedly installed with a top plate 8. The bottom mold body 9 is sleeved at the center of the top plate 8. The inner cavity of the ring pipe 7 is pre-set with an alternating component 13. The alternating component 13 includes a central disk 1301 pre-set at the center of the inner cavity of the ring pipe 7, and a rectangular array of copper disks 1319 on the outer side of the central disk 1301. The top of a set of copper disks 1319 is in contact with the bottom mold body 9. The rotating assembly 13, consisting of a central disc 1301, a first motor 1302, a second motor 1308, a winding shaft 1309, a pull rope, and a cylinder 1305, facilitates the automatic and cyclical switching of multiple copper discs 1319 between the states of contacting the bottom mold body 9 to absorb heat and immersing it in the cooling pool 1 to dissipate heat. This allows the heat-absorbing part of the bottom mold body 9 to be quickly removed and cooled, while the cooled part can be immediately replenished to the working position. This overcomes the bottleneck of long cooling waiting time for a single bottom mold body 9 in traditional methods, and greatly improves the continuity of high-temperature glass forming operations and overall production efficiency.

[0023] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the outer rectangular array of the central disk 1301 has an extension tube 1314, and the interior of the central disk 1301 has a central groove 1313 extending to one end. The inner side of the central disk 1301 has a connecting groove 1315 about the rectangular array of the central groove 1313, and the connecting groove 1315 connects the interior of the central groove 1313 and the extension tube 1314.

[0024] Furthermore, one end of the central disk 1301 has a rectangular array of inwardly recessed first locking grooves 1307. The central disk 1301 is fitted with a cylinder 1305 through the first locking grooves 1307. The inner side of the central disk 1301 has a movable groove 1316. The first locking groove 1307 is connected to the connecting groove 1315 through the movable groove 1316.

[0025] Furthermore, a pressure plate 1306 is fixedly installed at the output end of cylinder 1305. The pressure plate 1306 is circular, and the central disc 1301 is sleeved with the pressure plate 1306 through a movable groove 1316. Mounting discs 1304 are installed on the inner sides of the four sets of cylinders 1305. A first motor 1302 is snapped onto the end of the mounting disc 1304 away from the central disc 1301. A first mounting shaft 1303 is symmetrically installed on the outer side of the first motor 1302. The first motor 1302 is located outside the cylinders 1305, with a gap between it and the cylinders, for the purpose of providing power for the rotation of the cylinders 1305. The first mounting shaft 1303 is connected to the inner side of the ring tube 7. When in use, the first motor 1302 is started to drive the mounting plate 1304, which is engaged with its output end, to rotate. This, in turn, cooperates with the cylinder 1305 mounted on the outside of the mounting plate 1304 to drive the center plate 1301 to rotate. At the same time, by starting the cylinder 1305, it pushes the pressure plate 1306 mounted on its output end to move. This allows the pressure plate 1306 to move from the inside of the movable groove 1316 to the inside of the connecting groove 1315 and to press against the inside of the center plate 1301.

[0026] Furthermore, a second motor 1308 is pre-installed at one end of the center disk 1301 opposite to the first motor 1302. A second mounting shaft 1321 is symmetrically mounted on the outer side of the second motor 1308, and the second mounting shaft 1321 is fixedly connected to the outer side of the center disk 1301.

[0027] Furthermore, the central disk 1301 is rotatably sleeved with a winding shaft 1309 via a central groove 1313. The winding shaft 1309 has an inwardly extending second engaging groove 1320 at one end located outside the central disk 1301. The winding shaft 1309 is engaged with the output end of the second motor 1308 via the second engaging groove 1320. In use, the winding shaft 1309 engaged with it can be rotated by starting the second motor 1308.

[0028] Furthermore, a partition plate 1310 is fixedly installed on the outer side of the winding shaft 1309. A first pull rope 1311 and a second pull rope 1312 are wound at intervals on the outer side of the winding shaft 1309. Two sets of each of the first pull ropes 1311 and second pull ropes 1312 are provided, and they are vertically distributed. The first pull ropes 1311 and second pull ropes 1312 are located at both ends of the partition plate 1310. The two sets of first pull ropes 1311 and two sets of second pull ropes 1312 extend through four sets of connecting grooves 1315 to the inner side of the extension tube 1314. During use... The rotating winding shaft 1309 can drive the first pull rope 1311 and the second pull rope 1312 to rotate, thereby realizing the winding and unwinding of the first pull rope 1311 and the second pull rope 1312. Since the first pull rope 1311 and the second pull rope 1312 pass through different connecting grooves 1315 respectively, when the cylinder 1305 drives the pressure plate 1306 to move, the first pull rope 1311 or the second pull rope 1312 can be squeezed and fixed, so that when the winding shaft 1309 unwinds the line, one or more individual lines can be unwound.

[0029] Furthermore, a telescopic shaft 1317 is rotatably sleeved inside the extension tube 1314. The bottoms of the four sets of telescopic shafts 1317 are respectively connected to the first pull rope 1311 and the second pull rope 1312. The top of the telescopic shaft 1317 is fixedly connected to the outer side of the copper disc 1319. A return spring 1318 is sleeved on the outer side of the telescopic shaft 1317. The two ends of the return spring 1318 are respectively connected to the inner side of the copper disc 1319 and the outer side of the central disc 1301. In use, when the winding shaft 1309 winds the first pull rope 1311 and the second pull rope 1312, the telescopic shaft 1317 and the copper disc 1319 can be pulled towards the inner side of the central disc 1301 through the first pull rope 1311 and the second pull rope 1312, thereby squeezing... Pressing the return spring 1318 allows the first motor 1302 and the center plate 1301 to rotate the four sets of copper plates 1319, enabling the replacement of different copper plates 1319 and achieving alternating heat dissipation for the bottom mold body 9. Simultaneously, the cylinder 1305 and the pressure plate 1306 can be combined to squeeze and lock a single first pull rope 1311 or second pull rope 1312, thereby allowing the unrestricted first pull rope 1311 or second pull rope 1312 to retract one or more copper plates 1319. The copper plates 1319 located inside the cooling pool 1 can reciprocate and extend individually, increasing the flow of coolant in the cooling pool 1 cavity while cooling and dissipating heat, thus making heat transfer faster and more uniform.

[0030] like Figure 2 , Figure 3 and Figure 4As shown, heat dissipation fins 10 are symmetrically installed on the inner side of the ring pipe 7. Side plates 11 are fixedly installed on the inner side of the two sets of heat dissipation fins 10, and the side plates 11 are heat-conducting plates. Water-absorbing cotton 12 is fixedly installed on the inner side of one set of side plates 11. The size of the water-absorbing cotton 12 is larger than the size of the copper plate 1319. In use, when the copper plate 1319, which is cooled by the cooling pool 1, comes into contact with the set of side plates 11, it can perform preliminary heat dissipation through the combination of the side plates 11 and the heat dissipation fins 10. After the copper plate 1319 is cooled by the coolant in the inner cavity of the cooling pool 1, it can absorb and remove the coolant carried on the outer surface of the copper plate 1319 in contact with the water-absorbing cotton 12.

[0031] Furthermore, a top groove 6 is provided on the top of the cooling pool 1. The top groove 6 matches the copper plate 1319. The copper plate 1319 extends through the top groove 6 into the inner cavity of the cooling pool 1 and dissipates heat through the coolant. An inlet pipe 14 and an outlet pipe 15 are respectively installed at both ends of the cooling coil 2. The inlet pipe 14 and the outlet pipe 15 extend through the side wall of the cooling pool 1 to its outer side. The inlet pipe 14 and the outlet pipe 15 facilitate the delivery of fluorine coolant into the interior of the cooling coil 2. Both the first motor 1302 and the second motor 1308 are geared motors with self-locking output shafts.

[0032] Working principle: Multiple copper disks 1319 are driven by the rotating component 13 to alternately contact the bottom mold body 9 carrying the high-temperature glass to absorb heat, and then immersed in the cooling pool 1 for heat dissipation, thereby achieving a continuous and efficient cooling cycle; after the device is started, the copper disks 1319 in the working position are kept in contact with the bottom mold body 9 under the support of the return spring 1318, absorbing the heat of the high-temperature glass transferred by it; when rotation is required, the first motor 1302 is started, and the first mounting shaft 1303 drives the mounting disk 1304 and the cylinder 1305 connected to it to rotate, thereby driving the central disk 1301 and all the copper disks 1319 on the outside of it to rotate together, realizing the revolution rotation of the position of the copper disks 1319; Meanwhile, the individual lifting and lowering of the copper disc 1319 is controlled by the second motor 1308 and the first pull rope 1311 and the second pull rope 1312; the second motor 1308 drives the winding shaft 1309 to rotate within the central groove 1313, and the partition 1310 fixed on the winding shaft 1309 separates its outer side, thereby winding the first pull rope 1311 and the second pull rope 1312 at intervals; these pull ropes extend through different connecting grooves 1315 to the inside of the extension tube 1314 and are connected to the bottom of the telescopic shaft 1317; when the winding shaft 1309 winds the pull ropes, the pull ropes pull the telescopic shaft 1317. Overcoming the elastic force of the return spring 1318, the copper disc 1319 is driven to retract and descend towards the inner side of the central disc 1301; when the first pull rope 1311 or the second pull rope 1312 is released, the return spring 1318 pushes the copper disc 1319 and the telescopic shaft 1317 to extend and rise outward; the cylinder 1305 pushes the pressure plate 1306 through the movable groove 1316 into the connecting groove 1315, which can selectively squeeze and lock a specific first pull rope 1311 or second pull rope 1312, thereby realizing independent lifting and lowering control of one or more copper discs 1319, while the other copper discs 1319 remain in the same position; During its descent, the copper disc 1319, requiring cooling, passes through the top groove 6 at the top of the cooling pool 1 and is immersed in the coolant within its inner cavity. The cooling coils 2 within the cooling pool 1 circulate refrigerant coolant through the inlet pipe 14 and outlet pipe 15, working together with the coolant in the pool to quickly remove the heat absorbed by the copper disc 1319. The inlet pipe 3 and outlet pipe 4 are used to circulate and refresh the pure water in the cooling pool 1. The copper disc 1319, rotated into the cooling pool 1, can also agitate the coolant through controlled reciprocating lifting and lowering motion, enhancing heat exchange efficiency. The cooled copper disc 1319 rises and detaches from the cooling pool 1 under the action of the first pull rope 1311 or the second pull rope 1312 release and the return spring 1318. During the rotation and rotation process with the central disc 1301, the rising copper disc 1319 will pass through the water-absorbing cotton 12 inside the ring pipe 7, and the coolant carried on its surface will be absorbed clean, ensuring that it contacts the bottom mold body 9 again in a dry state. In addition, if the copper disc 1319 comes into contact with the side plate 11 in the rotation path, it can be assisted in heat conduction and heat dissipation through the side plate 11 and the heat dissipation fins 10. Through the coordinated operation of the rotation controlled by the first motor 1302, the lifting motion controlled by the second motor 1308, and the selective locking achieved by the cylinder 1305, the device can continuously rotate the copper disk 1319 in contact with the bottom mold body 9, so that the heat absorption and heat dissipation processes are separated in space and overlapped in time, thereby achieving continuous, uniform and efficient cooling of the high-temperature glass bottom mold body 9; the observation window 5 facilitates the monitoring of the coolant level inside the cooling pool 1.
