[0021] Reference Figure 1 , Figure 2 The utility model discloses a hot oil temperature regulating oil distribution system, including an oil distribution pipe, a main circulation oil circuit and a branch circulation oil circuit. The main circulation oil circuit includes a main pump, a main oil barrel, a main oil supply pipe 3 and a main oil return pipe 6. One end of the main oil return pipe 6 is connected to the main oil supply pipe 3 and the other end of the main oil return pipe 6 is connected to the main oil barrel, so that the main pump is connected to the main oil barrel through the main oil supply pipe 3 and the main oil return pipe 6 to form a main circulation. The branch circulation oil circuit includes a plurality of branch pumps 4, a plurality of branch oil barrels 5, a plurality of branch oil supply pipes 7, a plurality of branch oil return pipes 8, and the The branch pump 4 is also connected to the corresponding mold and the branch oil barrel 5 through a pipeline so that the branch pump 4 can supply the oil in the branch oil barrel 5 to the mold for heating. The branch oil return pipe 8 is connected to the main oil barrel and the corresponding mold so that the cooled oil can flow back to the main oil barrel for reheating. The main oil supply pipe 3 is connected to the branch oil supply pipe 7 through an oil distribution pipe, so as to transport the heated oil to the branch oil barrel 5. Valves are provided on the main return oil pipe 6, the branch oil supply pipe 7 and the branch return oil pipe 8. The valves are ordinary solenoid valves or ordinary water valves.

[0022] Because the present application directly burns and heats the oil in the heating bin by burning the combustible gas in the combustion chamber, and then the heating bin is connected to the main pump through a pipeline to provide hot oil. Of course, the other end of the heating bin is connected to the main oil barrel. The combustion chamber and the heating bin are existing technical designs and are not the improvement points of the present application. Therefore, the specific structure is not described in detail. The heated oil then enters the branch oil barrel 5 through the oil distribution pipe and the branch oil supply pipe 7. The above structure can realize dynamic heating of the oil, thereby realizing rapid heating and can be burned and used immediately. However, the above heating method is difficult to achieve oil temperature regulation. The oil temperature after combustion and heating is relatively high, so it cannot be directly supplied to the mold for use, and can only be adjusted through the branch oil barrel 5 for use.

[0023] As a preferred structure, it also includes a branch return oil pipe 2 9, which is connected to the corresponding mold and the branch oil barrel 5. The branch return oil pipe 2 9 is also provided with a valve. Through the above structure, a closed loop can be formed between the branch oil barrel 5 and the mold of the present application. Because the temperature required by the mold is within a range of values, if the oil temperature in the branch oil barrel 5 is within the corresponding range, there is no need to supply oil through the main oil supply pipe 3 to increase the temperature, and self-circulation heating is sufficient. In this way, the main circulation oil circuit can stop heating, thereby avoiding waste.

[0024] As shown in the figure, it also includes a square box body 1. The main body of the box body 1 is welded with steel and steel plates. A partition plate 2 is provided in the box body 1. The support oil barrels 5 are arranged on the partition plate 2, and the support pumps 4 are installed on the bottom plate of the box body 1. The support oil barrels 5 of the present application are arranged in two rows in parallel on the partition plate 2, and the support pumps 4 are also arranged in two rows in parallel on the bottom plate. In order to avoid the temperature of the support pumps 4 being too high, a cooling fan is provided on the side panel of the box body 1.

[0025] The principle of the present application is that when the mold starts working, the valve on the main oil return pipe 6 is in a closed state, and the combustible gas in the combustion chamber burns to directly burn and heat the oil in the heating bin. The oil in the main oil supply pipe 3 is pumped into the oil branch pipe through the main pump. The oil branch pipe is actually a multi-way, because the present application has eight branch oil barrels 5, and thus the oil branch pipe has eight outlets and one inlet. The oil branch pipe introduces the oil into the corresponding branch oil barrels 5 respectively. After the branch oil barrels 5 are full, the temperature is adjusted through natural cooling, the valve on the main oil return pipe 6 is opened, the main circulation oil circuit is opened, and the oil in the main oil barrel is circulated and heated. When the oil in the branch oil barrel 5 reaches the required temperature, the valve on the branch oil supply pipe 7 is closed, the valve on the branch oil return pipe 9 is opened, and the branch pump 4 starts working to realize the oil in the branch oil barrel 5 from The branch oil barrel 5 circulates internally to the mold until the temperature of the oil is lower than the lower limit of the temperature required by the mold. At this time, the valves on the main oil supply pipe 3 and the branch oil return pipe 9 are closed, and the valves on the branch oil supply pipe 7 and the main oil return pipe 6 are opened. The branch pump 4 will transport the oil in the branch oil barrel 5 to the mold and then return it to the main oil barrel. At the same time, the main pump will extract the cold oil in the main oil barrel and send it to the corresponding branch oil barrel 5 through the oil distribution pipe after combustion and heating to realize the external circulation of the oil, thereby ensuring that the temperature of the oil in the branch oil barrel 5 steadily increases until it reaches the upper limit of the temperature required by the mold, and then the internal circulation mode starts until the oil temperature in the branch oil barrel 5 is lower than the lower limit of the temperature required by the mold, and then the external circulation mode starts, and the above process works repeatedly.

[0026] The hot oil temperature regulating and oil separation system provided by the embodiment of the utility model is introduced in detail above. The principle and implementation mode of the utility model are explained in this article by using specific examples. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. At the same time, for the general technicians in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation mode and the scope of application. In summary, the content of this specification should not be understood as a limitation on the utility model.
