In summary, this invention allows the oil pump to draw heat transfer oil from the mold temperature controller's oil storage tank by switching the solenoid valve. After impurities are filtered through the coarse and fine filters of the purification mechanism, the oil is returned to the system, achieving online purification of the heat transfer oil. The transparent outer cylinder facilitates observation of impurity accumulation, and the removable top cover makes filter cleaning convenient. When oil replenishment is needed, switching the solenoid valve allows the oil pump to draw oil from the replenishment tank and deliver it to the mold temperature controller's oil storage tank through the replenishment pipe.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold temperature controller technology, and in particular to an online purification and oil replenishment device for heat transfer oil in mold temperature controllers. Background Technology
[0002] During the operation of the mold temperature controller, the heat transfer oil is prone to contamination with impurities due to long-term circulation. If it is not purified in time, it will affect the heat transfer efficiency and aggravate the wear and tear of the equipment. At the same time, the heat transfer oil may become insufficient due to evaporation and leakage, and oil needs to be replenished in time to ensure the normal operation of the mold temperature controller. In existing technologies, heat transfer oil purification often requires shutdown to extract and filter the oil, and oil replenishment also frequently requires manual operation. This not only leads to long downtime for the mold temperature controller and affects production efficiency, but also results in incomplete purification and low oil replenishment accuracy, making it difficult to meet the cleanliness and quantity requirements of the heat transfer oil for continuous and stable operation of the mold temperature controller. Therefore, in response to the above situation, there is an urgent need to develop an online heat transfer oil purification and replenishment device that can switch solenoid valves to allow the oil pump to draw heat transfer oil from the mold temperature controller's oil storage tank. After passing through the coarse and fine filters of the purification mechanism to filter impurities, the oil is returned to the system. The transparent outer cylinder facilitates observation of impurity accumulation, and the removable top cover facilitates filter cleaning. When oil replenishment is needed, switching the solenoid valve allows the oil pump to draw oil from the replenishment tank and deliver it to the mold temperature controller's oil storage tank through the replenishment pipe. The entire operation does not require shutdown, combining purification and oil replenishment functions, improving the efficiency and stability of the mold temperature controller's heat transfer oil usage, thus overcoming the shortcomings of current practical applications and meeting current needs.

The mold temperature controller oil storage tank 1 is connected to the oil circuit system on the mold temperature controller via an oil pipeline. The inlet end of the oil pump 2 is connected to the No. 1 tee connector 4, and the outlet end of the oil pump 2 is connected to the No. 2 tee connector 5. One end of the first oil suction pipe 6 is connected to the No. 1 tee connector 4, and the other end is connected to the replenishment tank 3. The replenishment tank 3 stores spare oil. A first solenoid valve 601 is installed on the first oil suction pipe 6. One end of the second oil suction pipe 10 is connected to the No. 1 tee connector 4, and the other end is connected to the mold temperature controller's oil storage tank 1. A fourth solenoid valve 1001 is installed on the second oil suction pipe 10. One end of the oil replenishment pipe 7 is connected to the No. 2 tee connector 5, and the other end is connected to the mold temperature controller's oil storage tank 1. A second solenoid valve 701 is installed on the oil replenishment pipe 7, which controls the oil circuit switch status of the oil replenishment pipe 7. A flow sensor 702 is installed on the oil replenishment pipe 7, which can detect the amount of oil replenished. One end of the first return oil pipe 8 is connected to the No. 2 tee connector 5, and the other end is connected to the net... The bottom of the purification mechanism 9 is connected to the first oil return pipe 8, and a third solenoid valve 801 is installed on the first oil return pipe 8. The purification mechanism 9 is connected to the mold temperature controller oil storage tank 1. The purification mechanism 9 includes: an outer cylinder 901, a second oil return pipe 902, a top cover 903, a coarse filter screen 904, a fine filter screen 905, and a connecting rod 906. The bottom of the outer cylinder 901 is connected to the first oil return pipe 8. The second oil return pipe 902, which is connected to the mold temperature controller oil storage tank 1, is installed on the upper left of the outer cylinder 901. The top cover 903 is detachably connected to the top of the outer cylinder 901 by threads. A sealing ring 9031 is fixed inside the top cover 903 to maintain a seal. The filter screen 904 is located below the fine filter screen 905. Two connecting rods 906 are fixed to the lower side of the top cover 903 and are fixed to the coarse filter screen 904 and the fine filter screen 905. The mesh size of the coarse filter screen 904 is larger than that of the fine filter screen 905. The coarse filter screen 904 is used to filter large particulate impurities in the oil, and the fine filter screen 905 is used to filter small particulate impurities in the oil. The outer cylinder 901 is made of transparent material so that people can see the accumulation of impurities on the coarse filter screen 904 and the fine filter screen 905 through the outer cylinder 901. When there are many impurities, the top cover 903 can be unscrewed and the coarse filter screen 904 and the fine filter screen 905 can be taken out for cleaning.

[0020] Working principle: This online purification and replenishment device for the heat transfer oil of the mold temperature controller operates as follows: When in the purification phase, the first solenoid valve 601 and the second solenoid valve 701 are closed, while the third solenoid valve 801 and the fourth solenoid valve 1001 are open. The oil pump 2 draws oil from the mold temperature controller's oil storage tank 1 through the second suction pipe 10, and then transports the oil from the first return pipe 8 to the outer cylinder 901. The oil passes through the coarse filter 904 and the fine filter 905 in sequence, and then flows back to the mold temperature controller's oil storage tank 1 through the second return pipe 902. Large particulate impurities in the oil are filtered by the coarse filter 904, and the fine filter 905 further filters out impurities. Small particulate impurities in the oil are removed, thus purifying the oil in the mold temperature controller's oil storage tank 1. When a person looks through the outer cylinder 901 at the accumulation of impurities on the coarse filter 904 and fine filter 905, if there are many impurities, the top cover 903 can be unscrewed, and the coarse filter 904 and fine filter 905 can be removed and cleaned. When oil needs to be replenished, the first solenoid valve 601 and the second solenoid valve 701 are opened, and the third solenoid valve 801 and the fourth solenoid valve 1001 are closed. The oil pump 2 draws oil from the replenishment tank 3 through the first oil suction pipe 6, and then replenishes the oil to the mold temperature controller's oil storage tank 1 through the oil replenishment pipe 7.
