Description

Technical Field

[0001] The invention relates to the technical field of die-casting automation, in particular to a release agent constant temperature treatment device. Background Art

[0002] The products produced by the spraying system need to be demolded with a release agent. At present, water-based release agents are widely used in the industry for demolding, and oil-based release agents have also begun to be used recently. Oil-based release agents are easier to demold than water-based release agents. Therefore, the research on the performance of oil-based release agents has also begun to deepen. One of the important indicators of its characteristics is viscosity.

[0003] At present, all the release agents supplied by the proportioning machines of die-casting manufacturers are at room temperature, without heating devices and liquid circulation devices, which leads to a great impact on the viscosity of the release agent in the seasons with large temperature differences between summer and winter. In winter, the oil will gradually cool and solidify after the die-casting machine is shut down for a period of time, and the interaction force between the molecules of the oily release agent will increase, that is, the Reynolds number will increase. At this time, the force required to push the release agent forward will increase, thus affecting the production of the product. The temperature in some areas of Northeast China can reach -20℃, so the release agent may be frozen after the die-casting machine is shut down for a period of time, resulting in the inability of the die-casting machine to produce parts.

[0014] Beneficial effects:

[0015] 1. When the release agent is output from the release agent outlet, the liquid level of the device decreases, and the release agent is input into the heating circulation barrel at the release agent inlet.

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] Please refer to Figure 1-5 The release agent constant temperature treatment device of the present invention comprises a heating circulation barrel 1. The heating circulation barrel 1 is used as the main structure of the device for installing related parts and performing constant temperature treatment on the release agent. A stirring pump 2 is arranged on the top of the heating circulation barrel 1. A stirring blade 16 is arranged inside the heating circulation barrel 1. A rotating shaft 17 is arranged at the bottom of the stirring pump 2. The bottom of the rotating shaft 17 is connected to the stirring blade 16, that is, the stirring pump 2 drives the stirring blade 16 to rotate through the rotating shaft 17, so that the heat of the release agent in the heating circulation barrel 1 is stirred evenly. A heating circulation barrel cover plate 3 is arranged on one side of the top of the heating circulation barrel 1. The heating circulation barrel cover plate 3 is folded and switched on the heating circulation barrel 1, and the current liquid level can be checked through the heating circulation barrel cover plate 3.

[0027] A circulation mechanism is arranged on one side of the bottom of the heating circulation barrel 1, and the circulation mechanism is used to drive the release agent to circulate. The circulation mechanism includes a release agent circulation port 13, and a release agent inlet 9 is arranged on one side of the release agent circulation port 13. The liquid pumped by the diaphragm pump enters the heating circulation barrel 1 from the release agent circulation port 13, and a release agent outlet 10 is arranged on the other side of the release agent circulation port 13. The diaphragm pump pumps the release agent in the barrel out from the release agent outlet 10, and the released release agent will eventually return to the heating circulation barrel 1 through the release agent circulation port 13. A cooling water outlet 12 is arranged above the release agent circulation port 13, and a cooling water inlet 11 is arranged above the cooling water outlet 12. When the temperature of the release agent in the barrel is higher than 30°C, the cooling water enters the interior of the heating circulation barrel 1 through the cooling water inlet 11, and the cooling water outlet 12 is used to discharge the cooling water inside the heating circulation barrel 1.

[0028] A thermocouple 7 is arranged on the other side of the bottom of the heating circulation barrel 1. The thermocouple 7 is used to monitor the current temperature of the release agent. A plurality of non-contact capacitive sensors are arranged above the thermocouple 7. The non-contact capacitive sensors monitor the liquid level inside the heating circulation barrel 1. The plurality of non-contact capacitive sensors include a first non-contact capacitive sensor 6, a second non-contact capacitive sensor 5, and a third non-contact capacitive sensor 4 from bottom to top, that is, the liquid level is detected in sequence by the first non-contact capacitive sensor 6, the second non-contact capacitive sensor 5, and the third non-contact capacitive sensor 4. A heating rod 15 is arranged at the bottom of the inner side of the heating circulation barrel 1. The heating rod 15 is used to heat the release agent. Mounting plates 14 are arranged on both sides of the heating rod 15. The mounting plates 14 on both sides are used to fix the heating rod 15. A drain port 8 is arranged at the bottom of the heating circulation barrel 1. When the equipment is maintained, the release agent in the barrel is drained through the drain port 8.

[0029] The working principle of the present invention is as follows: when the device is used, the mold release agent is input into the heating circulation barrel 1 through the mold release agent inlet 9. As the liquid level rises, the first non-contact capacitance sensor 6, the second non-contact capacitance sensor 5, and the third non-contact capacitance sensor 4 light up in sequence, the mold release agent inlet 9 stops replenishing liquid, the heating rod 15 heats the mold release agent, the stirring pump 2 drives the stirring blade 16 to rotate through the rotating shaft 17 to evenly distribute the heat of the mold release agent, and the thermocouple 7 monitors the temperature of the mold release agent in the heating circulation barrel 1. When the temperature of the heating rod 15 is When the temperature is too high, the channels of the cooling water inlet 11 and the cooling water outlet 12 will be opened, and the cooling water will enter the heating circulation barrel 1 to cool down the release agent in the heating circulation barrel 1. After reaching the set temperature, the channels of the cooling water inlet 11 and the cooling water outlet 12 will be closed, and the liquid level will drop after the release agent is output from the release agent outlet 10, and the release agent will be input into the heating circulation barrel 1 by the release agent inlet 9. The subsequent steps will be repeated. When the die-casting machine is shut down, the release agent in the pipeline will return to the heating circulation barrel 1 through the release agent circulation port 13, thereby realizing the circulation of the release agent.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
