[0002] The main function of the oil-based release agent is to enable the die-cast part to be removed from the mold cavity. It forms a thin film after being sprayed on the high-temperature surface of the mold, protects the surface of the cavity, prevents the casting from sticking to the mold, reduces the impact of the molten metal on the mold cavity during the injection molding of the casting, and reduces the wear between the casting and the mold cavity. In addition, the oil-based release agent can also play a lubricating role, improve the formability of the casting, increase the mold life, and ensure the quality of the die-cast part to a certain extent.

[0003] However, the viscosity of the oil-based release agent changes with temperature, and the change in viscosity has a great impact on its fluidity. Furthermore, the change in fluidity will affect its spraying effect, and ultimately affect the product quality. At the same time, the release agent stock solution is directly pumped into the sprayer through a diaphragm pump, and the mixed air also enters the sprayer, affecting the spraying effect. And the flowing release agent needs to prevent the mixing of air to avoid affecting the spraying quality. Therefore, in the integrated die-casting production, the requirement for a stable flow rate of the release agent is particularly important. Summary of the Utility Model

The types, quantities and proportions of the components in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0037] As Figures 1-4 shown, an embodiment of the present application discloses a constant temperature device for an oil-based mold release agent, including a container 1, a conveying structure, a circulating structure and a control unit. The conveying structure is arranged on the container 1 and is used to input and output the oil-based mold release agent 11 from the container 1. The circulating structure is arranged inside and outside the container 1 and is used to control the temperature of the oil-based mold release agent 11 in the container 1. The control unit is electrically connected to the conveying structure and the circulating structure and is used to control the operation of the conveying structure and the circulating structure.

[0038] In this embodiment, the oil-based release agent 11 is first transported into the container 1 through the transport structure, and then transported out of the container 1. During this process, the pressure inside the container 1 can be adjusted to facilitate the input and output of the oil-based release agent 11 and reduce the influence of the mixed air. Then, through the circulation structure, the temperature of the release agent inside the container 1 can be adjusted according to the temperature changes in different environments to maintain the appropriate viscosity of the oil-based release agent 11 inside the container 1, so that the spraying amount of the oil-based release agent 11 is normal, thereby improving the production quality and reducing the production cost. Finally, the control unit controls the operation of the transport structure and the circulation structure to make the entire device work more intelligently.

[0039] In this embodiment, the container 1 is one of a pressure kettle and a pressure tank, preferably a pressure tank. The type of the container 1 can also be selected appropriately according to the actual situation.

[0040] In some embodiments, as Figure 1 shown, the transport structure includes an input pipe 21, an output pipe 22, and a pressure regulating pipe 23. One end of the input pipe 21 is connected to the upper part of the container 1 for inputting the external oil-based release agent 11 into the container 1. One end of the output pipe 22 is connected to the bottom of the container 1, and the other end passes through the container 1 for connecting to the sprayer 25, so that the oil-based release agent 11 inside the container 1 can be sprayed into the mold through the sprayer 25. One end of the pressure regulating pipe 23 is connected to the top of the container 1, and a pressure regulating valve 231 is arranged on the pressure regulating pipe 23 for adjusting the pressure inside the container 1. On the one hand, it is beneficial to the input and output of the oil-based release agent 11 inside the container 1; on the other hand, part of the air inside the container 1 can be discharged, further reducing the possibility of air being output along with the output pipe 22.

[0041] In this embodiment, the pressure regulating valve 231 can be one of a proportional valve, an air pressure regulating valve, a solenoid valve, etc., preferably an air pressure regulating valve. The appropriate valve can also be selected according to the actual situation.

[0042] Through the mutual cooperation of the pressure tank, the input pipe 21, the output pipe 22, and the pressure regulating pipe 23, compared with the previous diaphragm pump directly sucking and supplying to the sprayer 25 for spraying, the entry of air can be reduced, and the possibility of generating bubbles during the transportation can be reduced, so as to improve the use quality of the oil-based release agent 11. During the input process of the oil-based release agent 11, the pressure inside the pressure tank can be adjusted to negative pressure first, which is not only beneficial to the input but also beneficial to discharging the mixed air. When outputting, it is adjusted to positive pressure again.

[0043] In this embodiment, in order to further reduce the bubbles that may be generated during the transportation process, a filtering structure 221 is arranged inside the output pipe 22. The filtering structure 221 is set as a filter screen, and the filter screen is at least 100 meshes. The appropriate mesh number of the filter screen can also be selected according to the actual situation. In order to monitor the amount of the oil-based release agent 11 transported by the output pipe 22, a flow sensor 24 is installed on the output pipe 22.

[0044] In this embodiment, a sprayer 25 is assembled at the free end of the output pipe 22 so that the oil-based mold release agent 11 can be sprayed into the mold through the sprayer 25.

[0045] In some embodiments, as Figures 2-3 shown, the circulation structure includes an external cooling circulation member, an internal cooling circulation member, a heating member 31, and a stirring structure 32. The external cooling circulation member is disposed on the outer wall of the container 1 and is used to cool or keep warm the medium in the pressure tank. The internal cooling circulation member is disposed inside the container 1 and is used to cool the medium in the pressure tank. The heating member 31 is disposed inside the container 1 and is staggered from the internal cooling circulation member and is used to heat the medium in the pressure tank.

[0046] Through the mutual cooperation of the external cooling circulation member and the internal cooling circulation member, it is possible to quickly cool the oil-based mold release agent 11 in the container 1 in a high-temperature environment and reduce the influence of the external temperature on the oil-based mold release agent 11 in the container 1; and then through the heating member 31, it is possible to heat the container 1 in time in a cold external environment, reduce the influence of the cold environment on the oil-based mold release agent 11, and can also reduce the influence of the external cold situation on the oil-based mold release agent 11 in the container 1 through the external cooling circulation member and the internal cooling circulation member.

[0047] In this embodiment, as Figure 2 shown, the external cooling circulation member is set as the first circulation pipe 33. The first circulation pipe 33 is spirally arranged on the outer wall of the container 1. The bottom end of the first circulation pipe 33 is for liquid inlet and the top end is for liquid outlet. It can introduce a coolant in a high-temperature environment to effectively cool the oil-based mold release agent 11 in the pressure tank; and can also introduce hot water or a hot liquid medium in a cold environment to keep the oil-based mold release agent 11 in the pressure tank warm and reduce the influence of the external environment. Of course, in this case, the temperature and type of the heat medium can be selected according to the actual situation.

[0048] In this embodiment, as Figure 3 shown, the internal cooling circulation member is set as the second circulation pipe 35. The second circulation pipe 35 is arranged inside the container 1. The water inlet end and the water outlet end of the second circulation pipe 35 are both arranged at the bottom of the container 1. The second circulation pipe 35 can be spirally arranged on the inner wall of the pressure tank or can be arranged at the bottom of the pressure tank, and a suitable arrangement method can also be selected according to the actual situation. In a high-temperature situation, by introducing a cooling medium into the second circulation pipe 35, it is possible to quickly cool the oil-based mold release agent 11 in the pressure tank, cooperate with the first circulation pipe 33, can accelerate the cooling efficiency, and has a simple structure and strong practicability.

[0049] In this embodiment, the heating element 31 is positioned at the edge of the pressure tank and staggered with the second circulation pipe 35 to prevent the heating element 31 from interfering with the second circulation pipe 35 during operation. The heating element 31 can be configured for electrical heating, steam heating, or other heating methods, preferably electrical heating, in this case using a thermocouple. Alternatively, a suitable heating method can be selected based on actual conditions. In cold conditions, the operation of the thermocouple can rapidly heat the oil-based release agent 11 within the pressure tank.

[0050] In this embodiment, during heating, hot water, hot steam, etc. may be introduced into the second circulation pipe 35 to accelerate the heating of the bottom of the pressure tank, reduce the heating time, and improve efficiency.

[0051] In this embodiment, the stirring structure 32 includes a stirring shaft and stirring blades. The stirring shaft is positioned in the center of the container 1, and the stirring blades are arranged on the stirring shaft. These stirring blades are used to accelerate the heating or cooling of the oil-based release agent 11 within the pressure tank by stirring, while also reducing air bubbles generated by the mixing. To prevent bubbles from being generated by stirring, the stirring speed should be less than 60 r / min.

[0052] In some embodiments, as Figures 1-3 As shown, the control unit includes multiple controllers and a temperature sensor 34. The delivery mechanism and circulation mechanism are electrically connected to the multiple controllers for controlling their respective operations. The temperature sensor 34 is disposed within the container 1 and is electrically connected to one of the controllers. This monitors the temperature of the oil-based release agent 11 within the pressure tank in real time, allowing for timely adjustment of the temperature of the oil-based release agent 11 according to the situation, maintaining a constant temperature as much as possible to prevent viscosity from affecting the spraying effect.

[0053] In this embodiment, the multiple controllers are respectively a temperature controller 341, a stirring controller 321, an external cooling cycle controller 331, an internal cooling cycle controller 351, a flow controller 241, and a heating controller 311. The temperature controller 341 is electrically connected to the temperature sensor 34, the stirring controller 321 is electrically connected to the control motor of the stirring shaft, the external cooling cycle controller 331 is electrically connected to the water pump of the first circulation pipe 33, the internal cooling cycle controller 351 is electrically connected to the water pump of the second circulation pipe 35, the flow controller 241 is electrically connected to the flow sensor 24, and the heating controller 311 is electrically connected to the thermocouple.

[0054] In this embodiment, the controller also includes a PLC controller 100, a central controller, etc., preferably a PLC controller 100. The PLC controller 100 is electrically connected to the temperature controller 341, the stirring controller 321, the external cooling cycle controller 331, the internal cooling cycle controller 351 and the flow controller 241, and is used to control the corresponding work according to the set program.
