Description

Technical Field

[0001] This utility model relates to the technical field of mold cooling devices, and specifically to an automatic rotary air blowing cooling device for mold tempering. Background Technology

[0002] Mold tempering is an important part of the mold heat treatment process. Its purpose is to eliminate the internal stress generated in the mold during quenching by controlling the heating temperature, holding time and cooling method, so as to avoid cracking or deformation caused by stress concentration. At the same time, it adjusts the balance of hardness and toughness of the mold, reduces dimensional changes during long-term use or storage, and ensures that the mold maintains high dimensional accuracy in processing (such as optical molds, electronic connector molds).

[0003] Traditional mold cooling methods mainly employ natural cooling, fixed air cooling, or water cooling: natural cooling depends on ambient temperature, takes a long time, and is easily affected by external interference; fixed air cooling achieves cooling by blowing air in one direction, which is efficient but suffers from uneven cooling and many blind spots, especially for molds with complex structures, where the cooling effect is limited; water cooling is fast, but requires a water circulation system and is prone to causing oxidation or corrosion on the mold surface. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an automatic rotary air-blowing cooling device for mold tempering. The device utilizes an air-cooling unit mounted on a base, including an intake fan, cooling pipe network, coolant tank, and circulating radiator. The cooling pipe network absorbs heat energy from the gas inside the air-cooling tank, and the coolant, after being restored to its operating temperature by the circulating radiator, continues to circulate. This solves the problems of excessively long natural cooling time, susceptibility to external interference, and limited efficiency of fixed air cooling, achieving a stable cooling effect with continuous supply of cold air and maintaining high-efficiency heat absorption. The rotary air-blowing unit's rotational drive mechanism drives the air guide shroud to rotate, which rotates stably via an annular slide rail assembly. The circumferentially distributed air guide pipes, in conjunction with a booster fan, increase airflow pressure, solving the problems of uneven cooling and numerous blind spots in traditional fixed air cooling. This achieves uniform cooling of the mold surface through multi-angle rotary air blowing. The coordinated operation of the circulating transfer unit, air-cooling unit, and rotary air-blowing unit eliminates the need for manual intervention in the cooling and transfer process after mold tempering, achieving a stable, automated operation of the entire cooling and transfer process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic rotary air-blowing cooling device for tempering molds includes a base, on which an air-cooling unit is mounted to supply cold air to cool the tempering mold. A rotary air-blowing unit is located on one side of the air-cooling unit to evenly blow airflow onto the mold surface for cooling. A circulation transfer unit is located on one side of the rotary air-blowing unit to transfer the mold. The air-cooling unit includes an air-cooling box mounted on the base, an air inlet fan located at the air inlet of the air-cooling box, and a cooling pipe network located on one side of the air inlet fan. The system includes a coolant tank connected to one end of the inlet pipe of the cooling pipe network, and a circulating radiator connected to one end of the outlet pipe of the cooling pipe network and the inlet end of the coolant tank. The intake fan is used to send gas into the air-cooled box, the cooling pipe network is used to absorb the heat energy of the gas in the air-cooled box, and the circulating radiator is used to restore the working temperature of the coolant. The air-cooled box has a square cross-section and a hollow interior. A wind tunnel is provided on one side, and at least one layer of grille is provided on the side of the air inlet. The grille is used to protect the intake fan, and the ventilation gap between the grilles is 5.5mm-10.5mm.

[0006] The grille has two layers, with a ventilation gap of 3.5mm-5.5mm between the second layer grilles. The two layers of grilles form a mesh to prevent debris from being sucked in.

[0007] The rotary blower unit includes a mounting base on one side of the base, a rotary drive mechanism on the mounting base, and a blower mechanism rotatably connected to the rotary drive mechanism.

[0008] The rotary drive mechanism includes a rotary outer box, a drive motor mounted on the rotary outer box, a rotary shaft mounted on the output end of the drive motor, and a rotating gear mounted on the rotary shaft. The rotary outer box has openings at both ends, and the opening on one side of the rotary outer box is connected to the air tunnel on one side of the air-cooled box through a ventilation pipe.

[0009] The blower mechanism includes an air guide shroud arranged in the rotating outer box via at least one annular slide rail, a plurality of air guide ducts arranged circumferentially on the air guide shroud, and a booster fan arranged at the air inlet end of the air guide ducts.

[0010] The circulating transfer unit includes a movable support, a drive assembly disposed within the movable support, tension rollers disposed at both ends of the movable support via ball bearings, a conveyor belt disposed on the tension rollers, a support plate disposed on the conveyor belt, a limiting support disposed at one upper end of the movable support, and a push mold mechanism disposed on the other side of the movable support.

[0011] The push-molding mechanism includes a push cylinder mounted on a movable support via a cylinder plate and a push plate located at the output end of the push cylinder.

[0012] The movable support includes several vertical support columns, horizontal connecting columns disposed between the vertical support columns, and casters disposed below the vertical support columns.

[0013] The drive assembly includes a rotary motor fixedly connected to a movable bracket via a motor code plate, and a drive wheel located at the output end of the rotary motor.

[0014] The tensioning roller includes a main tensioning roller and a secondary tensioning roller. One end of the main tensioning roller is provided with a driven wheel, which is connected to the driving wheel via a transmission belt.

[0015] The beneficial effects of this utility model are as follows: 1. The air-cooling unit set on the base includes an intake fan, cooling pipe network, coolant tank and circulating radiator. The cooling pipe network absorbs the heat energy of the gas in the air-cooled box, and the coolant is continuously circulated after being restored to the working temperature by the circulating radiator, thus achieving a stable cooling effect that continuously supplies cold air and maintains high-efficiency heat absorption capacity. 2. The air guide shroud is driven to rotate by the rotation drive mechanism of the rotary blowing unit. The air guide shroud rotates stably by the annular slide rail group. The circumferentially distributed air guide pipes, together with the booster fan, increase the airflow pressure, achieving the effect of uniform cooling of the mold surface by multi-angle rotary blowing. 3. Through the coordinated work of the circulating transfer unit, the air-cooling unit, and the rotary blowing unit, a stable operation effect of automating the entire cooling and transfer process is achieved.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings: like Figure 1-8As shown, this utility model relates to an automatic rotary air-blowing cooling device for tempering molds, including a base 1, which supports and fixes the installation position of an air-cooling unit 2, forming a stable support; the air-cooling unit 2 is provided on the base 1, which supplies cold air to cool the tempering mold; a rotary air-blowing unit 3 is provided on one side of the air-cooling unit 2, which blows air evenly onto the mold surface for cooling; a circulation transfer unit 4 is provided on one side of the rotary air-blowing unit 3, which transfers the mold; the air-cooling unit 2 includes an air-cooling box 20 provided on the base 1, an air inlet fan 21 provided at the air inlet of the air-cooling box 20, a cooling pipe network 22 provided on one side of the air inlet fan 21, and a cooling pipe network 22. The air-cooled box 20 is connected to a coolant tank 23 at one end of an inlet pipe 220, and a circulating radiator 24 is connected to one end of the outlet pipe 221 of the cooling pipe network 22 and the inlet end of the coolant tank 23. An intake fan 21 is used to send air into the cooling pipe network 22 inside the air-cooled box 20. The cooling pipe network 22 absorbs the heat energy of the air in the air-cooled box 20. The air-cooled box 20 has a square cross-section and a hollow interior. A wind tunnel 200 is provided on one side, from which directional cold air is output. At least one layer of grilles 201 is provided on the air inlet side to protect the intake fan 21. The ventilation gaps between the grilles 201 are 5.5mm-10.5mm. The air-cooled box 20 provides a space for cold air generation, and its square hollow structure, combined with the intake fan 21 at the air inlet... 1. External air is introduced, and the air inlet can be extended to the outside through an extended air duct to facilitate air exchange. The coolant tank 23 contains coolant, and the outlet of the coolant tank 23 is connected to the cooling pipe network 22 through the inlet pipe 220. When the coolant flows in the cooling pipe network 22, it absorbs the heat of the gas in the air-cooled box 20, completing heat exchange. The circulating radiator 24 is used to achieve the working temperature of the coolant (lower than the mold exit temperature). It includes a heat exchanger, heat dissipation fin assembly, forced air cooling system, and temperature control module. The coolant, after absorbing the heat of the gas in the air-cooled box 20, enters the circulating radiator 24 through the outlet pipe 221 of the cooling pipe network 22. It first flows through the built-in heat exchanger, which adopts a spiral coil structure to increase the heat exchange area, so that the coolant and the heat dissipation fins are connected. The heat dissipation fins are in full contact and are made of aluminum alloy with high thermal conductivity. At the same time, the axial fan draws in ambient air from one side of the radiator. The high-speed airflow passes through the gaps in the heat dissipation fins and quickly removes the heat from the fins through forced convection. The temperature control module monitors the coolant temperature in real time. When the coolant temperature is detected to be higher than the set threshold, the fan speed is automatically increased to improve the heat dissipation efficiency. If the coolant temperature remains high, auxiliary cooling is activated. The refrigerant is circulated by the compressor to further reduce the coolant temperature. The heated coolant is cooled back to its initial state through heat dissipation treatment and then returns to the coolant tank 23 through the inlet to form a continuous circulation. This ensures that the cooling pipe network 22 always has a high efficiency of heat absorption, thereby maintaining a continuous supply of cold air to the air-cooled unit 2.

[0026] like Figure 4 As shown, the grille 201 is further provided with two layers, wherein the ventilation gap between the second layer grille 201 is 3.5mm-5.5mm, and the two layers of grille 201 form a mesh to prevent debris from being sucked in.

[0027] like Figure 1-2 As shown in Figures 5-7, the rotary blower unit 3 includes a mounting base 30 on one side of the base 1, a rotary drive mechanism 31 on the mounting base 30, and a blower mechanism 32 rotatably connected to the rotary drive mechanism 31. The mounting base 30 is used to fix the rotary drive mechanism 31 to one side of the base 1, providing a stable mounting base for the rotary blower unit 3. The rotary drive mechanism 31 is used to drive the blower mechanism 32 to rotate, so as to achieve uniform circumferential airflow. The rotary drive mechanism 31 includes a rotary outer box 310, a drive motor 311 mounted on the rotary outer box 310, a rotary shaft 312 mounted on the output end of the drive motor 311, and a rotating gear 313 mounted on the rotary shaft 312. The rotary outer box 310 is used to accommodate and support the rotary drive mechanism 31 and the blower mechanism 32. The rotary outer box 310 has openings 3100 at both ends. Through a ventilation pipe 5, the opening 3100 on one side of the rotary outer box 310 is connected to the air duct 200 on one side of the air-cooled box 20 to form a cold air delivery channel. The blower mechanism 32 includes an air guide shroud 321 disposed within the rotating outer casing 310 via at least one annular slide rail assembly 320, a plurality of air guide ducts 322 circumferentially disposed on the air guide shroud 321, and a booster fan 323 disposed at the air inlet end of the air guide ducts 322. The annular slide rail assembly 320 includes an annular guide rail and a slider slidably connected to the annular guide rail. One end of the air guide shroud 321 is provided with an annular gear 3210 that meshes with the rotating gear 313. The air outlet 3220 at the other end of the air guide duct 322 is arranged towards the mold. The drive motor 311 is used to provide rotational power and transmits the power to the rotating shaft 312. Gear 313 converts the rotational motion of the motor into the rotation of the gear. This rotating gear 313 meshes with the ring gear 3210 of the air guide shroud 321 to drive the air guide shroud 321 to rotate synchronously. The ring slide rail assembly 320 supports the air guide shroud 321 to rotate stably within the rotating outer box 310, reducing rotational friction and maintaining stability. The air guide shroud 321 sends the airflow out through the circumferentially arranged air guide duct 322. The air guide duct 322 blows the cold air in the air-cooled box 20 to the mold surface. The booster fan 323 increases the airflow pressure in the air guide duct 322 to ensure that the airflow covers the mold surface after it is blown out.

[0028] like Figure 8As shown, the circulating transfer unit 4 includes a movable support 40, a drive assembly 41 disposed within the movable support 40, tension rollers 42 disposed at both ends of the movable support 40 via ball bearings, a conveyor belt 43 disposed on the tension rollers 42, a support plate 44 disposed on the conveyor belt 43, a limiting bracket 45 disposed at one upper end of the movable support 40, and a push-die mechanism 48 disposed on the other side of the movable support 40. The support plate 44 is slidably connected to the movable support 40 via two slide rail assemblies 46 disposed on the side of the movable support 40. The slide rail assembly 46 includes a linear guide rail and a linear slider slidably connected to the linear guide rail. The movable support 40 includes a plurality of vertical support columns 400, horizontal connecting columns 401 disposed between the vertical support columns 400, and casters 402 disposed below the vertical support columns 400. The drive assembly 41 includes a rotary motor 411 fixedly connected to the movable support 40 via a motor encoder 410, and a drive wheel 412 located at the output end of the rotary motor 411. The tension roller 42 includes a primary tension roller and a secondary tension roller. One end of the primary tension roller is provided with a driven wheel 47, which is connected to the drive wheel 412 via a transmission belt 413. The push-die mechanism 48 includes a push cylinder 481 mounted on the movable support 40 via a cylinder encoder 480, and a push plate 482 located at the output end of the push cylinder 481.The movable support 40 is used to connect the vertical support column 400 and the horizontal connecting column 401 through welding or locking bolts to form a stable support frame. The casters 402 below allow for flexible movement and position adjustment of the movable support 40. The drive assembly 41 drives the drive wheel 412 to rotate via a rotary motor 411, transmitting power to the driven wheel 47 of the tension roller via a transmission belt 413, thus enabling the active operation of the conveyor belt 43. The tension roller 42 maintains the tension of the conveyor belt 43, ensuring smooth operation without deviation. The conveyor belt 43 rotates cyclically in cooperation with the drive assembly 41 and the tension roller 42, driving the support plate 44 and the mold to reciprocate horizontally. The support plate 44 carries the mold and is slidably connected to the movable support 40 via a slide rail assembly 46, ensuring mold stability during transport. The limiting bracket 4... 5 is used to position the mold cooling station after the support plate 44 is moved into place, to prevent the mold from shifting due to inertia or external force during the transfer process; the push mold mechanism 48 is used to push the mold; the slide rail group 46 is used to make the support plate 44 move smoothly along the preset path; the push cylinder 481 is fixed to the moving bracket 40 through the cylinder plate 480, and the linear extension and retraction motion of its output end is converted into a pushing force on the mold through the push plate 482; the rotary motor 411 is fixed to the moving bracket 40 through the motor plate 410, and the driving wheel 412 of its output end is connected to the driven wheel 47 of the main tensioning roller through the transmission belt 413 to provide power for the operation of the conveyor belt 43; the circulating transfer unit 4 forms a circulating transfer of the mold, and together with the air cooling unit 2 and the rotary blowing unit 3, realizes the automated cooling and transfer function of the mold tempering process.

[0029] Workflow: After the mold completes the tempering process, it enters the cooling station through the circulation transfer unit 4. The rotary motor 411 of the drive assembly 41 is fixed to the moving bracket 40 through the motor plate 410. Its output end drive wheel 412 is connected to the driven wheel 47 of the tensioning roller via the transmission belt 413. The support plate 44 on the surface of the conveyor belt 43 is slidably connected to the moving bracket 40 through the slide rail group 46 to ensure the mold's position is stable during horizontal reciprocating movement. The air-cooling unit 2 starts synchronously. The air-cooling box 20 on the base 1 introduces external air through the air inlet. The air intake fan 21 sends the gas into the cooling pipe network 22 inside the air-cooling box 20. The cooling pipe network 22 absorbs the heat energy of the gas to achieve initial cooling. The circulating coolant in the coolant tank 23 flows into the cooling pipe network 22 through the liquid inlet pipe 220. After heat exchange, the coolant enters the circulating radiator 24 through the liquid outlet pipe 221 to restore the working temperature. The cooled air is output through the wind tunnel 200. The rotating outer box 310 of the rotary blowing unit 3 is connected to the air-cooling unit 20 through the ventilation pipe 5. The air duct 20 and the air chamber 200 are connected to form a cold air delivery channel. The drive motor 311 drives the rotating gear 313 through the rotating shaft 312, which meshes with the ring gear 3210 of the air guide shroud 321 of the blower mechanism 32. The air guide shroud 321 rotates stably in the rotating outer box 310 through the ring slide rail assembly 320. The circumferentially distributed air guide pipes 322 receive cold air from the air-cooled box 20. The booster fan 323 increases the airflow pressure to ensure that the cold air output from the air outlet 3220 covers the mold surface, realizing multi-angle rotating air blowing cooling. After the mold completes the cooling process, it enters the mold pushing mechanism 48 station through the circulation transfer unit 4. The pushing cylinder 481 of the mold pushing mechanism 48 is fixed to the moving bracket 40 through the cylinder plate 480. Its pushing plate 482 pushes the mold away from the support plate 44 to the next station. Through the coordinated work of the air-cooling unit 2, the rotating air blowing unit 3 and the circulation transfer unit 4, the entire process of automated cooling and transfer of the mold after tempering is completed, ensuring the cooling efficiency and operational stability of the mold.
