Description

Technical Field

[0001] This utility model relates to the field of precision mold cooling technology, and in particular to a precision mold cooling device. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping.

[0003] A search revealed application CN202122795279.5, which describes a rapid cooling device for a precision mold. The device includes an upper mold and a lower mold. Two support plates are fixed to the bottom wall of the lower mold. A vertical rod is fixed to the side wall of one of the support plates. A groove is provided on the side wall of the vertical rod, and a threaded rod is rotatably connected within the groove. A drive motor connected to the threaded rod is located on the upper wall of the vertical rod. The upper mold is connected to the threaded rod via a lifting mechanism. The lower mold has a stabilizing mechanism that cooperates with the upper mold. One of the support plates has an inner cavity containing coolant. A pressing plate is slidably connected within the inner cavity. This invention, by setting up an inner cavity, coolant, pressing plate, and cooling channel, allows the pressing plate to move upwards within the inner cavity using a fixed rod when the upper and lower molds open. This allows the coolant above the pressing plate to be delivered into the cooling channel through a water outlet, thus cooling the item in the lower mold.

[0004] The prior art describes a rapid cooling device for a precision mold. It relies on the lifting and lowering of the upper mold to move the extrusion plate and drive the circulation of coolant. The cooling speed is limited by the micro-speed rotation of the drive motor (mold opening speed). If the mold needs to open quickly (such as in high-speed production scenarios), the upward speed of the extrusion plate will be accelerated, which may cause the coolant to complete the circulation before it has fully absorbed heat, resulting in a decrease in cooling effect. Conversely, if the mold opening speed is too slow, the circulation efficiency will be low.

[0005] Therefore, we propose a precision mold cooling device. Utility Model Content

[0006] The present invention aims to solve the technical problems existing in the prior art and provide a precision mold cooling device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a precision mold cooling device, comprising a support block, a stabilizing horizontal plate, a lower mold, and an upper mold. The support block has an internal cavity for storing coolant. A sliding vertical rod is slidably mounted within the cavity, with its top end passing through the lower mold and connecting to the bottom of the upper mold. Water inlet pipes are fixedly mounted at the left and right ends of the upper rear inner wall of the cavity, and miniature circulation pumps are fixedly mounted at the outlet ends of the two water inlet pipes. Electromagnetic flow regulating valves are fixedly mounted at the other ends of the two miniature circulation pumps. Water outlet pipes are fixedly mounted at the left and right ends of the lower rear inner wall of the cavity, and miniature radiators are fixedly mounted at the outlet ends of the two water outlet pipes. An extrusion plate is fixedly installed at the bottom of the sliding vertical rod. Two water inlet pipes are located above the extrusion plate, and two water outlet pipes are located below the extrusion plate. Several through holes are opened at the top of the extrusion plate, and a one-way water inlet valve is installed in each through hole. A cooling channel is opened inside the lower mold and is connected to the water inlet pipe. An installation vertical block is fixedly installed in the middle of the rear side wall of the support block. A drive motor is fixedly installed on the top of the installation vertical block. An L-shaped support plate is fixedly installed on the housing of the drive motor. A speed sensor is fixedly installed on the top of the support plate. A metal gear plate is fixedly installed on the shaft of the drive motor. The probe of the speed sensor is aligned with the metal gear plate. Both the probe of the speed sensor and the metal gear plate are located inside the upper end of the installation vertical block.

[0008] Furthermore, a controller is fixedly installed on the upper right side wall of the mounting block, and a temperature monitor is embedded in the top inner wall of the mounting cavity. The micro circulation pump, electromagnetic flow regulating valve, temperature monitor, and speed sensor are all connected to the controller via signals.

[0009] Furthermore, the left and right inner walls of the mounting cavity are respectively provided with guide grooves along the vertical direction, and guide sliders are slidably installed in the two guide grooves respectively. The two guide sliders are respectively fixedly installed on the left and right side walls of the extrusion plate.

[0010] Furthermore, a vertical sliding groove is provided on the upper end of the front side wall of the mounting block, a threaded rod is rotatably installed in the vertical sliding groove, a connecting slider is threaded on the outer wall of the threaded rod, the connecting slider is slidably installed in the vertical sliding groove, and the upper end of the threaded rod is fixedly installed on the output end of the drive motor.

[0011] Furthermore, the middle part of the rear sidewall of the upper mold is fixedly connected to the front sidewall of the connecting slider.

[0012] Furthermore, the top of the support block is fixedly installed at the bottom rear end of the lower mold, and a support plate is fixedly installed at the bottom front end of the lower mold.

[0013] Furthermore, a sturdy horizontal plate is fixedly installed between the support plate and the support block.

[0014] This invention provides a precision mold cooling device. It has the following beneficial effects:

[0015] 1. This precision mold cooling device, in use, utilizes the cooperation of components such as a support block, lower mold, upper mold, mounting vertical block, sliding vertical rod, drive motor, extrusion plate, water inlet pipe, micro circulation pump, and electromagnetic flow regulating valve. The drive motor rotates the threaded rod, while the connecting slider on the outer wall of the threaded rod cannot rotate due to the restriction of the grooved extrusion plate, but can only slide along the axial direction of the threaded rod. This pushes the upper mold to rise uniformly relative to the lower mold, completing the mold opening action. When the upper mold rises, the sliding vertical rod drives the extrusion plate to move upward in the mounting cavity. The coolant above the extrusion plate is circulated through the micro circulation system. The pump actively provides power, replacing the passive drive of the original extrusion plate, and accelerates the flow of coolant. At the same time, the electromagnetic flow regulating valve dynamically adjusts the flow rate based on the speed of the drive motor and feedback from the speed sensor. If the mold opening speed is fast, the motor speed is high, the pump speed increases, the valve opening increases, and the coolant flow rate accelerates, ensuring that more low-temperature coolant contacts the mold per unit time, compensating for the shortened single cycle time caused by the fast mold opening. If the mold opening speed is slow, the motor speed is low, the pump speed decreases, and the valve opening decreases, avoiding local stagnation and overheating caused by excessively slow coolant flow, thus improving the cooling effect.

[0016] 2. This precision mold cooling device, during use, utilizes the coordinated operation of components such as a support block, water outlet pipe, miniature radiator, temperature monitor, and controller. The temperature monitor at the top of the mounting cavity continuously monitors the coolant temperature changes. When the coolant heats up due to continuous heat absorption, the controller activates the miniature radiator on the water outlet pipe to forcibly reduce the temperature of the coolant flowing through the pipe. Simultaneously, the controller increases the speed of the miniature circulation pump, shortening the coolant's residence time within the radiator and accelerating heat dissipation. This ensures that the coolant temperature drops to the set threshold when returning to the mounting cavity. The cooled coolant then returns to the area below the extrusion plate in the mounting cavity through the water outlet pipe, completing one "heat absorption-heat dissipation" cycle. This achieves active control of the coolant and improves its practicality.

[0017] 3. In use, this precision mold cooling device utilizes the cooperation between components such as the support block, sliding vertical rod, extrusion plate, and guide slider. During the use of this device, the rising of the sliding vertical rod causes the extrusion plate to rise within the mounting cavity, and the rising of the extrusion plate causes the guide slider to move upward along the guide groove. Through the cooperation of the guide slider and the guide groove, the extrusion plate becomes more stable during its movement within the mounting cavity. Attached Figure Description

Detailed Implementation

[0025] Example 1

[0026] A precision mold cooling device, such as Figure 1-4As shown, the device includes a support block 1, a stabilizing horizontal plate 2, a lower mold 3, and an upper mold 4. The support block 1 has an internal mounting cavity 25 for storing coolant. A sliding vertical rod 6 is slidably mounted within the mounting cavity 25. The top of the sliding vertical rod 6 passes through the lower mold 3 and connects to the bottom of the upper mold 4. Water inlet pipes 9 are fixedly mounted on the upper left and right ends of the rear inner wall of the mounting cavity 25. Miniature circulation pumps 10 are fixedly mounted on the outlet ends of the two water inlet pipes 9, and electromagnetic flow regulating valves 11 are fixedly mounted on the other ends of the two miniature circulation pumps 10. Water outlet pipes 12 are fixedly mounted on the lower left and right ends of the rear inner wall of the mounting cavity 25, and miniature radiators 13 are fixedly mounted on the outlet ends of the two water outlet pipes 12. An extrusion plate 8 is fixedly mounted at the bottom of the sliding vertical rod 6. Both water inlet pipes 9 are located above the extrusion plate 8, and both water outlet pipes 12 are located below the extrusion plate 8. The top of the extrusion plate 8 has a... Several through holes 14 are provided, each with a one-way water inlet valve. A cooling channel is provided inside the lower mold 3, which is connected to the water inlet pipe 9. A mounting block 5 is fixedly installed in the middle of the rear side wall of the support block 1. A drive motor 7 is fixedly installed on the top of the mounting block 5. An L-shaped support plate 18 is fixedly installed on the housing of the drive motor 7. A speed sensor 19 is fixedly installed on the top of the support plate 18. A metal gear plate 20 is fixedly installed on the shaft of the drive motor 7. The probe of the speed sensor 19 is aligned with the metal gear plate 20. The probe of the speed sensor 19 and the metal gear plate 20 are both located inside the upper end of the mounting block 5. A controller 21 is fixedly installed on the upper right side wall of the mounting block 5. A temperature monitor 17 is embedded in the top inner wall of the mounting cavity 25. The micro circulation pump 10, the electromagnetic flow regulating valve 11, the temperature monitor 17, and the speed sensor 19 are all connected to the controller 21.

[0027] In this embodiment, during use, the supporting block 1, lower mold 3, upper mold 4, mounting vertical block 5, sliding vertical rod 6, drive motor 7, extrusion plate 8, water inlet pipe 9, micro circulation pump 10, electromagnetic flow regulating valve 11, and other components work together to drive the threaded rod 23 to rotate. The connecting slider 24 on the outer wall of the threaded rod 23 cannot rotate due to the restriction of the grooved extrusion plate 8, and can only slide along the axial direction of the threaded rod 23, thereby pushing the upper mold 4 to rise at a constant speed relative to the lower mold 3 to complete the mold opening action. When the upper mold 4 rises, the sliding vertical rod 6 drives the extrusion plate 8 to move upward in the mounting cavity 25, and the cooling above the extrusion plate 8... The coolant is actively powered by a micro-circulating pump 10, replacing the passive drive of the extrusion plate 8, thus accelerating the flow of coolant. At the same time, the electromagnetic flow regulating valve 11 dynamically adjusts the flow rate based on the rotational speed of the drive motor 7, fed back by the speed sensor 19. If the mold opening speed is fast, the motor speed is high, the pump speed increases, the valve opening increases, and the coolant flow rate accelerates, ensuring that more low-temperature coolant contacts the mold per unit time, thus compensating for the shortened single cycle time caused by the fast mold opening. If the mold opening speed is slow, the motor speed is low, the pump speed decreases, and the valve opening decreases, preventing localized overheating due to excessively slow coolant flow rate, thereby improving the cooling effect.

[0028] Through the coordinated operation of components such as the support block 1, water outlet pipe 12, miniature radiator 13, temperature monitor 17, and controller 21, the temperature monitor 17 at the top of the mounting cavity 25 monitors the coolant temperature changes in real time. When the coolant heats up due to continuous heat absorption, the controller 21 controls the miniature radiator 13 on the water outlet pipe 12 to start working, forcibly reducing the temperature of the coolant flowing through the water outlet pipe 12. The controller 21 simultaneously increases the speed of the miniature circulation pump 10, shortens the residence time of the coolant in the miniature radiator 13, accelerates the heat dissipation efficiency, and ensures that the temperature of the coolant drops to the set threshold when it returns to the mounting cavity 25. The cooled coolant returns to the extrusion plate 8 of the mounting cavity 25 through the water outlet pipe 12, completing one "heat absorption-heat dissipation" cycle, realizing active regulation of the coolant and improving its practicality.

[0029] Example 2

[0030] Based on Example 1, such as Figure 1-4 As shown, guide grooves 16 are respectively opened on the left and right inner walls of the mounting cavity 25 along the vertical direction. Guide sliders 15 are slidably installed in the two guide grooves 16 respectively. The two guide sliders 15 are respectively fixedly installed on the left and right side walls of the extrusion plate 8. A vertical groove 22 is opened on the upper end of the front side wall of the mounting block 5. A threaded rod 23 is rotatably installed in the vertical groove 22. A connecting slider 24 is threaded on the outer wall of the threaded rod 23. The connecting slider 24 is slidably installed in the vertical groove 22. The upper end of the threaded rod 23 is fixedly installed on the output end of the drive motor 7.

[0031] In this embodiment, during use, through the cooperation between the supporting block 1, sliding vertical rod 6, extrusion plate 8, guide slider 15 and other components, the rising of the sliding vertical rod 6 causes the extrusion plate 8 to rise within the mounting cavity 25. The rising of the extrusion plate 8 causes the guide slider 15 to move upward along the guide groove 16. Through the cooperation between the guide slider 15 and the guide groove 16, the extrusion plate 8 is made more stable during its movement within the mounting cavity 25.

[0032] The middle of the rear side wall of the upper mold 4 is fixedly connected to the front side wall of the connecting slider 24. The top of the support block 1 is fixedly installed at the bottom rear end of the lower mold 3. The bottom front end of the lower mold 3 is fixedly installed with a support plate 100. A stabilizing horizontal plate 2 is fixedly installed between the support plate 100 and the support block 1.

[0033] The working principle of this utility model is as follows: During use, through the cooperation of components such as the support block 1, lower mold 3, upper mold 4, mounting vertical block 5, sliding vertical rod 6, drive motor 7, extrusion plate 8, water inlet pipe 9, micro circulation pump 10, and electromagnetic flow regulating valve 11, the drive motor 7 drives the threaded rod 23 to rotate. The connecting slider 24 on the outer wall of the threaded rod 23 cannot rotate due to the restriction of the grooved extrusion plate 8, and can only slide along the axial direction of the threaded rod 23, thereby pushing the upper mold 4 to rise at a constant speed relative to the lower mold 3 to complete the mold opening action. When the upper mold 4 rises, the sliding vertical rod 6 drives the extrusion plate 8 to move upward in the mounting cavity 25, and the extrusion plate 8 is positioned above the... The coolant is actively powered by a micro-circulating pump 10, replacing the passive drive of the extrusion plate 8, thus accelerating the coolant flow. At the same time, the electromagnetic flow regulating valve 11 dynamically adjusts the flow rate based on the rotational speed of the drive motor 7, fed back by the speed sensor 19. If the mold opening speed is fast, the motor speed is high, the pump speed increases, the valve opening increases, and the coolant flow rate accelerates, ensuring that more low-temperature coolant contacts the mold per unit time, compensating for the shortened single cycle time caused by the fast mold opening. If the mold opening speed is slow, the motor speed is low, the pump speed decreases, and the valve opening decreases, avoiding localized overheating due to excessively slow coolant flow rate, thus improving the cooling effect.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
