Description

Technical Field

[0001] The present invention relates to the technical field of temperature detection and control of die casting molds, and in particular to a micro-spraying device for temperature detection and temperature control of die casting molds. Background Art

[0002] Lightweighting of new energy vehicles is a common research topic in the automotive industry, and die-casting technology for new energy vehicle components has also seen rapid development. Die-casting is a metal casting process that traditionally consists of four steps: mold preparation, filling, injection, and sand removal.

[0003] During the die-casting preparation process, the die-casting mold requires temperature control, and a release agent must be sprayed into the mold cavity. Controlling the die-casting mold surface temperature is crucial for producing high-quality die-casting parts. Uneven or inappropriate die-casting mold temperatures can lead to dimensional instability in the casting, deformation during ejection, and defects such as thermal stress, mold sticking, surface depressions, internal shrinkage holes, and thermal bubbles. Controlling the mold temperature helps reduce thermal stress and deformation, extending the mold's service life, thereby shortening the trial production cycle and reducing production costs. This has significant practical and application significance for enhancing the market competitiveness of die-casting parts. Currently, die-casting molds are generally temperature-controlled using mold chillers and water chillers. In addition to reducing friction between the die-casting mold's moving parts and extending its service life, release agents are also used to lower the mold's operating temperature and prevent thermal fatigue. They also serve as a parting agent between the die-casting mold and the die-casting, facilitating demolding after the casting is formed.

[0004] For example, patent publication number CN215088170U discloses a micro-spray atomizer for die-casting molds. By adjusting the amount of release agent sprayed by the spray assembly, this device achieves timed micro-spraying of the mold, improving mold release while also reducing mold temperature. However, after mold and water cooling, some areas of the mold surface still fall below standard temperature control and require further adjustment. This micro-spray atomizer is not suitable for spraying specific areas of the mold. Summary of the Invention

When the atomizing gas channel 1 and the control gas channel 1 are connected to the gas source at the same time, the control gas and the atomizing gas reach the nozzle at the same time, and the control gas opens the release agent nozzle hole of the nozzle to spray the release agent. After the atomizing gas is sprayed out from the atomizing gas nozzle hole, it contacts the release agent, thereby atomizing the release agent, and realizing the temperature control of the die-casting mold by controlling water evaporation; then the connection between the control gas channel 1 and the gas source is disconnected, and the release agent on the surface of the die-casting mold is blown dry by using the atomizing gas, and the temperature of the die-casting mold is controlled by air blowing; the combination of the two temperature controls can effectively improve the temperature control effect.

By making the two nozzle assemblies work simultaneously or at different times, the release agent can be sprayed on the die-casting molds in the two carrier plates simultaneously or at different times. When it is necessary to spray the die-casting molds in the two carrier plates at the same time, it is only necessary to connect the two routes of release agent, control gas and atomizing gas, so that the molds in the two carrier plates can be sprayed at the same time. When it is necessary to spray the mold of one carrier plate, it is only necessary to connect the route of release agent, control gas and atomizing gas corresponding to the carrier plate, so that the control gas, atomizing gas and release agent can reach the nozzle corresponding to the carrier plate.

[0058] 4. The present invention provides an angle block and selects angle blocks of different angles to change the installation angle of the nozzle to adapt to the spraying work of different die-casting molds, thereby achieving multiple uses of one item.

[0059] 5. The present invention provides an expansion block, and the expansion block is detachably connected to the spray seat. The requirements of different spraying distances can be met by selecting expansion blocks of different thicknesses. BRIEF DESCRIPTION OF THE DRAWINGS

The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0076] Example 1

[0077] This embodiment proposes a micro-spraying device for temperature detection and temperature control of die-casting molds, which is used to spray a release agent on the die-casting mold after mold cooling or water cooling. After mold cooling and water cooling, there are still some areas on the mold surface that do not meet the temperature control standards and still need to be controlled again. By spraying the release agent on the areas where the mold temperature control does not meet the standards, the release agent can help reduce friction between the moving parts of the die-casting mold, increase the service life, and also reduce the working temperature of the mold to avoid thermal fatigue of the mold. It can also serve as a parting agent for the die-casting mold and the die-casting, which helps to demold the casting after molding.

[0078] Please refer to Figure 1-Figure 3 The micro-spraying device for die-casting mold temperature detection and temperature control of this embodiment includes a spraying mechanism, a thermal imaging camera 2, and a controller 3. It may also include a mobile frame 4 that provides mounting support for the spraying mechanism and controller 3. The spraying mechanism includes a spraying seat 5, two nozzle assemblies, a mobile slide 6, and two supporting plates 7. It may also include two expansion blocks 12 and two mounting plates 13.

[0079] Two supporting plates 7 are arranged opposite each other, each with a recessed mounting cavity formed on one side. The supporting plates 7 are mounted on the movable frame 4 via brackets. The mounting cavity of the supporting plates 7 houses at least one fixed or movable die of a die-casting mold and collects excess release agent during spraying. A water baffle 11 is fixed to the bottom of the open side of the supporting plates 7 to prevent the release agent from flowing out.

[0080] The spraying station 5 is located between two supporting plates 7. It is equipped with two sets of release agent channels 1 for supplying release agent, two sets of atomizing gas channels 1 for supplying atomizing gas, and two sets of control gas channels 1 for supplying control gas. Each set of release agent channels 1 includes at least one release agent channel 1, each set of atomizing gas channels 1 includes at least one atomizing gas channel 1, and each set of control gas channels 1 includes at least one control gas channel 1. Multiple release agent inlet holes 1-5-1 are formed on both end surfaces of the spraying station 5, and each release agent channel 1 is connected to at least one release agent inlet hole 1-5-1. A movable slide 6 is used to support the spraying station 5 and drive the spraying station 5 to move between the two supporting plates 7.

[0081] Two expansion blocks 12 are removably mounted on either side of the spray station 5 via bolts. Each expansion block 12 corresponds to a group of release agent channel 1, a group of atomizing gas channel 1, and a group of control gas channel 1. Expansion blocks 12 are provided with a plurality of connecting holes 1, a plurality of connecting holes 2, and a plurality of connecting holes 3. Each of the release agent channel 1, atomizing gas channel 1, and control gas channel 1 corresponding to each expansion block 12 is connected to at least one connecting hole 1, one connecting hole 2, and one connecting hole 3, respectively. In actual production, expansion blocks 12 of various thicknesses can be produced, and the appropriate thickness can be selected for installation according to actual needs.

[0082] The two mounting plates 13 are detachably mounted on the two expansion blocks 12 by bolts, and a release agent channel 2, an atomizing gas channel 2, and a control gas channel 2 are provided in the mounting plate 13. The release agent channel 2 of the mounting plate 13 is connected to a plurality of connecting holes 1 of the corresponding expansion block 12, the atomizing gas channel 2 of the mounting plate 13 is connected to a plurality of connecting holes 2 of the corresponding expansion block 12, and the control gas channel 2 of the mounting plate 13 is connected to a plurality of connecting holes 3 of the corresponding expansion block 12. The release agent in the release agent channel 1 can reach the release agent channel 2 of the corresponding mounting plate 13 along the connecting hole 1 of the corresponding expansion block 12, the atomizing gas in the atomizing gas channel 1 can reach the atomizing gas channel 2 of the corresponding mounting plate 13 along the connecting hole 2 of the corresponding expansion block 12, and the control gas in the control gas channel 1 can reach the control gas channel 2 of the corresponding mounting plate 13 along the plurality of connecting holes 3 of the corresponding expansion block 12.

[0083] The two nozzle assemblies correspond to the two mounting plates 13 respectively. The nozzle assemblies include multiple nozzles 8 and multiple angle blocks 16. The multiple angle blocks 16 of the nozzle assembly are detachably mounted on the corresponding mounting plates 13 by bolts, and the angles formed between the angle blocks 16 and the mounting plates 13 are adjustable. Figure 4 、 Figure 5 The angle block 16 is provided with a release agent cavity 9, an atomizing gas cavity 10, and a control gas cavity 14. The release agent cavity 9, the atomizing gas cavity 10, and the control gas cavity 14 are respectively connected to the release agent channel 2, the atomizing gas channel 2, and the control gas channel 2 of the mounting plate 13. In each nozzle assembly, multiple nozzles 8 are detachably mounted on multiple angle blocks 16 by bolts. The nozzle 8 is provided with a release agent spray hole and multiple atomizing gas spray holes arranged around the release agent spray hole. The outlet of the release agent spray hole is provided with an air valve and is connected to the release agent cavity 9 and the control gas cavity 14 in the angle block 16. The atomizing gas spray hole is connected to the atomizing gas cavity 10 of the angle block 16. In this way, the release agent in the release agent channel 2 of the mounting plate 13 can reach the release agent spray hole of the nozzle 8 through the release agent hollow cavity 9, and the atomized gas in the atomized gas channel 2 of the mounting plate 13 can also reach the atomized gas spray hole of the nozzle 8 through the atomized gas hollow cavity 10, while the control gas in the control gas channel 2 of the mounting plate 13 reaches the release agent spray hole of the nozzle 8 through the control gas hollow cavity 14. The air valve of the release agent spray hole can be opened under the drive of the control gas and spray out the atomized gas and the release agent at the same time. After being sprayed, the release agent contacts the atomized gas and is atomized under the action of the atomized gas. When the control gas and release agent are stopped, the atomized gas spray hole of the nozzle 8 can continue to spray the atomized gas.

[0084] In this embodiment, since the mold release agent, control gas, and atomizing gas are divided into two routes and reach the two nozzle assemblies respectively, the mold release agent can be sprayed on the die-casting molds in the two carrier plates 7 at the same time or at different times by making the two nozzle assemblies work at the same time or at different times. When it is necessary to spray the die-casting molds in the two carrier plates 7 at the same time, it is only necessary to connect the two routes of mold release agent, control gas, and atomizing gas so that the control gas, atomizing gas, and mold release agent can reach the nozzles 8 of the two nozzle assemblies at the same time, and the molds in the two carrier plates 7 can be sprayed at the same time. When it is necessary to spray the mold of one carrier plate 7, it is only necessary to connect the mold release agent, control gas, and atomizing gas corresponding to the carrier plate 7 so that the control gas, atomizing gas, and mold release agent can reach the nozzle 8 of the nozzle assembly corresponding to the carrier plate 7.

[0085] It should be noted that in this embodiment, the spraying angle of the nozzle 8 can be adjusted by selecting angle blocks 16 of different angles to adapt to the spraying operation of different die-casting molds, thereby achieving multiple uses. The angle block 16 is connected to the spray seat 5 with bolts, which facilitates replacement and installation. In addition, the spraying distance between the nozzle 8 and the die-casting mold can be adjusted by selecting expansion blocks 12 of different thicknesses to meet the needs of different spraying distances. The expansion block 12 is connected to the spray seat 5 with bolts, which facilitates replacement and installation.

[0086] Thermal imaging camera 2 is used to capture thermal images of the die-casting molds within the two carrier plates 7. Because the fixed and movable molds of the die-casting molds still have areas of substandard temperature control after die-cooling or water-cooling, capturing thermal images of the fixed and movable molds with thermal imaging camera 2 quickly identifies areas where the surface temperature of the fixed and movable molds falls outside the predetermined temperature range.

[0087] The controller 3 controls the movable slide 6 to drive the spray seat 5 to move according to the image area in the thermal image obtained by the thermal imaging camera 2 where the temperature is not within the predetermined temperature range, thereby driving the nozzle 8 to spray the physical area (key point for mold temperature control) on the die-casting mold corresponding to the image area where the temperature is not within the predetermined temperature range, thereby realizing temperature detection and temperature control of the key point for mold temperature control.

[0088] Please refer to Figures 6-11To facilitate the continuous supply of release agent, atomizing gas, and control gas to release agent channel 1, atomizing gas channel 1, and control gas channel 1, respectively, the spray mechanism of this embodiment further includes a release agent barrel 1, an air source (not shown), a distribution block 17, multiple valve blocks 18, multiple control gas quick-connects 19, multiple atomizing control gas quick-connects 20, multiple control gas female connectors 21, multiple atomizing control gas female connectors 22, multiple control gas male connectors 31, multiple atomizing control gas male connectors 32, multiple hoses 1 (not shown), multiple hoses 2 (not shown), an air-liquid tank 23, an air inlet pipe 24, an air outlet pipe 25, a valve island 26, a liquid inlet pipe 27, a liquid outlet pipe 28, and a booster pump 29. The release agent barrel 1 and air-liquid tank 23 are mounted on a movable frame 4. The air inlet pipe 24, air outlet pipe 25, valve island 26, liquid inlet pipe 27, and liquid outlet pipe 28 are also mounted on the air-liquid tank 23.

[0089] One end of the inlet pipe 24 is connected to the air source, and the other end is connected to a tee 35. A pressure-regulating filter valve 1 30 is installed on the inlet pipe 24. The second end of the tee 35 is connected to one end of the outlet pipe 25. The third end of the tee 35 is connected to a gas distribution pipe (not shown), which is equipped with a pressure-regulating filter valve 2 (not shown). The gas source can be directly from the factory supply. Connect one end of the inlet pipe 24 to the factory supply pipeline. Adjust the filter valve 1 30 to adjust the pressure of the gas introduced into the inlet pipe 24 to 0.45-0.55 MPa to form atomizing gas. The pressure-regulating filter valve 2 further adjusts the pressure to 0.3-0.4 MPa to form control gas and atomizing control gas.

[0090] The valve island 26 is a control component composed of multiple electrically controlled valves. It integrates signal input / output and signal control, like a control island. The inlet of the valve island 26 is connected to the gas distribution pipe.

[0091] A plurality of control air male connectors 31 and a plurality of atomization control air male connectors 32 are respectively connected to a plurality of electric control valves on the valve island 26 through pipelines, thereby respectively receiving 0.3-0.4 MPa control air and atomization control air.

[0092] One end of liquid inlet pipe 27 is connected to one end of liquid outlet pipe 28, and the other end is connected to the outlet of booster pump 29. Booster pump 29 is fixed to release agent barrel 1, with its inlet connected to release agent barrel 1. The other end of liquid outlet pipe 28 is connected to multiple release agent inlet holes 5-1 of spray station 5. Booster pump 29 delivers release agent from release agent barrel 1 to release agent channel 1 of spray station 5 through liquid inlet pipe 27 and liquid outlet pipe 28.

[0093] The distribution block 17 is installed at the top of the spray seat 5. The distribution block 17 is provided with multiple control air holes 17-1. A control air channel 1 of the spray seat 5 is connected to at least one control air hole 17-1. During installation, the sealing between the distribution block 17 and the spray seat 5 must be ensured. Sealing measures such as sealing rings can be provided between the distribution block 17 and the spray seat 5. Multiple control air quick plugs 19 are respectively installed in the multiple control air holes 17-1. Multiple control air female connectors 21 are all installed on the distribution block 17. One end of the multiple hoses 1 is respectively connected to the multiple control air quick plugs 19 and the other end of the multiple hoses 1 is respectively connected to the multiple control air female connectors 21. The multiple control air female connectors 21 are respectively connected to the multiple control air male connectors 31. In this way, 0.3-0.4Mpa control air is introduced into the control air channel 1, and the opening and closing of the control air is controlled by the opening and closing of the solenoid valve connected to the control air male connector 31 on the control valve island 26.

[0094] The distribution block 17 is also provided with an atomized gas storage channel. The top of the distribution block 17 is equipped with an atomized gas connector 17-3 connected to the atomized gas storage channel. The atomized gas connector 17-3 is connected to the gas outlet pipe 25, thereby introducing and storing 0.45-0.55Mpa atomized gas into the atomized gas storage channel. The bottom of the distribution block 17 is also provided with multiple atomized gas outlet holes 17-2. An atomized gas channel 1 of the spray seat 5 is connected to at least one atomized gas outlet hole 17-2. The distribution block 17 is also provided with multiple atomized gas control holes 1 and multiple atomized gas control holes 2. The multiple atomized gas control holes 2 are respectively connected to the top ends of the multiple atomized gas control holes 1. The atomized gas control holes 1 have a lower half section connected to the atomized gas storage channel and an upper half section connected to the atomized gas outlet hole 17-2. Multiple atomization control air quick-connects 20 are installed in the multiple atomization control air holes 2, and multiple atomization control air female connectors 22 are installed on the distribution block 17. One end of multiple hoses 2 is connected to the multiple atomization control air quick-connects 20, and the other end of multiple hoses 2 is connected to the multiple atomization control air female connectors 22. The multiple atomization control air female connectors 22 are connected to the multiple atomization control air male connectors 32. In this way, 0.3-0.4 MPa atomization control air is introduced into the multiple atomization control air holes 2, and the atomization control air is controlled by opening and closing the solenoid valve connected to the atomization control air male connector 32 on the control valve island 26.

[0095] Multiple valve groups 18 are respectively installed in multiple atomization control air holes 1; the opening and closing of the valve group 18 is controlled by the on-off of the atomization control air, thereby controlling the on-off of the atomization air outlet 17-2 and the atomization air storage channel. Figure 12The valve assembly 18 includes a valve cover 18-1, a valve core 18-2, a valve spring 18-3, and a valve seat 18-4. The valve cover 18-1 is movably mounted on the top of the upper half of the bore section. Two spiral retaining rings 18-5 and a sealing ring 18-6 located between the two spiral retaining rings 18-5 are mounted on the outer surface of the valve cover 18-1 to prevent the atomization control air in the atomization control air hole 2 from entering the atomization air outlet hole. The diameter of the valve core 18-2 is larger than the aperture of the upper half of the bore section of the atomization control air hole 1. The valve core 18-2 is located in the lower half of the bore section and can move up and down within the lower half of the bore section. The top of the valve core 18-2 is equipped with a sealing ring 18-7, which is 0.3mm higher than the top surface of the valve core 18-2. The bottom surface area of ​​the valve core 18-2 is smaller than the top surface area of ​​the valve cover 18-1. The upper and lower ends of valve core 18-2 are connected to valve stem 18-8 and valve stem 2 18-9, respectively. The top end of valve stem 18-8 is connected to valve cover 18-1. Valve spring 18-3 is located within the lower half of the bore and fits over valve stem 2 18-9. When valve spring 18-3 is in its neutral position, valve core 18-2 blocks both the upper and lower halves of atomization control orifice 1. Valve seat 18-4 is fixed to the bottom end of the lower half of the bore and connected to valve spring 18-3 at its top. Seal ring 3 18-10 is fitted around valve seat 18-4, ensuring a tight seal between valve seat 18-4 and the wall of atomization control orifice 1, preventing leakage of atomized gas within the atomization gas storage channel. A clearance hole 18-11 is provided at the top of valve seat 18-4 to allow for clearance of valve stem 2 18-9. The distribution block 17 is also equipped with multiple exhaust connectors 15, which are respectively connected to the upper half of the multiple atomization control air holes 1. When 0.3-0.4Mpa atomization control air is introduced into the multiple atomization control air holes 2, the atomization control air squeezes the valve cover 18-1 of the valve group 18. Since the bottom surface area of ​​the valve core 18-2 is smaller than the top surface area of ​​the valve cover 18-1, the force exerted by the atomization control air on the valve cover 18-1 is greater than the force exerted by the atomization air in the atomization storage channel on the valve core 18-2. As a result, the valve cover 18-1 moves downward, and the atomization control air is directly discharged from the exhaust connector 15, thereby driving the valve core 18-2 to move downward. At this time, the upper half of the atomization control air hole 1 is connected to the lower half of the atomization control air hole 1, and the atomization air in the atomization gas storage channel enters the atomization gas outlet 17-2, enters the atomization gas channel 1, and finally enters the nozzle 8. When the corresponding solenoid valve on the valve island 26 is closed, the atomization control gas is disconnected, and the valve cover 18-1 and the valve core 18-2 are reset under the action of the valve spring 18-3, blocking the atomization gas storage channel and the atomization gas outlet 17-2. At this time, the atomization gas cannot enter the atomization gas channel 1.

[0096] Next, the working principle of the micro-spraying device for temperature detection and temperature control of the die-casting mold of this embodiment is explained: first, the fixed mold and the movable mold of the die-casting mold after mold cooling or water cooling are respectively fixed in two supporting plates 7, and the thermal image of the fixed mold and the movable mold is obtained by the thermal imaging camera 2. Through the thermal image, it is possible to see the image area on the fixed mold and the movable mold where the temperature is not within the predetermined temperature range. In this way, the physical area of ​​the fixed mold and the movable mold corresponding to the image area where the temperature is not within the predetermined temperature range can be accurately found, that is, the specific area on the fixed mold and the movable mold where the temperature is not within the predetermined temperature range and still needs to be regulated. The controller 3 controls the movable slide 6 to drive the spray seat 5 to move according to the image area where the temperature of the thermal image is not within the predetermined temperature range, so that the nozzle assembly corresponds to the specific area of ​​the fixed mold and / or the movable mold. After the spraying station 5 is moved into position, the controller 3 controls the booster pump 29 to start and simultaneously controls the solenoid valve connected to the nozzle assembly corresponding to the fixed mold and / or movable mold to be sprayed on the valve island 26 to open. The release agent, control gas, and atomized control gas simultaneously reach the nozzle 8 of the nozzle assembly corresponding to the fixed mold and / or movable mold. The air valve in the release agent spray hole of the nozzle 8 is driven by the control gas to open and simultaneously spray atomized gas and release agent. The release agent is atomized under the action of the atomized gas, thereby spraying and atomizing the release agent on the specific area of ​​the fixed mold and / or movable mold, and controlling the temperature of the die-casting mold by controlling water evaporation. Then, the controller 3 controls the electric control valve connected to the control gas male connector 31 on the valve island 26 to close and controls the booster pump 29 to stop. At this time, the control gas is disconnected, and the nozzle 8 is driven by the atomized gas to open and spray the atomized gas on the die-casting mold. The atomized gas is used to blow away the release agent on the surface of the die-casting mold, and the temperature of the die-casting mold is controlled by air purge. Finally, the controller 3 controls all the electrically controlled valves of the valve island 26 to be closed, the atomizing control gas is disconnected, and the atomizing gas is disconnected. The controller 3 controls the movable slide 6 to drive the spray seat 5 back to its original position, and controls the thermal imaging camera 2 to capture the temperature images of the fixed mold and the movable mold again. If the temperature is adjusted to the appropriate range, no secondary spraying is required. Otherwise, a second spraying is required. It should be noted that in order to facilitate the acquisition of thermal images of the die-casting mold, the thermal imaging camera 2 can be rotatably installed on the top of the distribution block 17. By rotating the thermal imaging camera 2, the thermal images of the die-casting molds in the two carrier plates 7 can be captured.

[0097] In this embodiment, to accommodate the needs of various production sites, the distribution block 17 is further provided with multiple second release agent inlet holes 17-4, which are connected to the first release agent channel. The liquid outlet pipe 28 is also connected to the second release agent inlet hole 17-4, allowing the release agent to flow into the first release agent channel along the second release agent inlet hole 17-4, facilitating the use of various scenarios. When the second release agent inlet hole 17-4 is not in use, it is sealed with a plug 17-5.

[0098] In this embodiment, the release agent barrel 1 is also equipped with a pneumatic stirring pump 33, a water inlet pipe 34, a pressure sensor, and a flow meter. The pneumatic stirring pump 33 is connected to the air distribution pipe via a pipeline. The release agent mixture is delivered into the release agent barrel 1 through the water inlet pipe 34 and is thoroughly stirred by the pneumatic stirring pump 33. The pressure sensor monitors the release agent pressure in real time, while the flow meter monitors the release agent flow rate in real time. A discharge pipe 39 is also provided at the bottom of the release agent barrel 1 to facilitate the discharge of the release agent.

[0099] In order to facilitate the recovery of the release agent and enable the release agent to be recycled, the micro-spraying device of this embodiment is also provided with two recovery barrels 36 and a pneumatic diaphragm pump 37 installed on the mobile frame 4, and a recovery pipe 38 is also provided on the release agent barrel 1. Return water ports are provided at the bottom of the two supporting plates 7. The two recovery barrels 36 are respectively located below the two recovery ports, and the excess release agent sprayed by the spraying mechanism will flow into the recovery barrel 36 along the recovery ports. The water inlet of the pneumatic diaphragm pump 37 is connected to the two recovery barrels 36 through a pipeline, and its water outlet is connected to the recovery pipe 38 of the release agent barrel 1. The release agent in the recovery barrel 36 is transported to the release agent barrel 1 by the pneumatic diaphragm pump 37, thereby realizing the recycling of the release agent. An angle seat valve can be installed on the recovery pipe 38 to control the recovery flow of the release agent.
