Description

Technical Field

[0001] The utility model relates to the technical field of high-gloss mold temperature machines, and specifically relates to a high-gloss mold temperature machine with a heat energy recovery function. Background Art

[0002] In modern manufacturing, the quality and appearance requirements of plastic products are getting higher and higher. In order to meet the market demand for high-quality plastic products, the high-gloss mold temperature machine, as a key auxiliary device, plays a crucial role. It can precisely control the mold temperature and provide stable and reliable process conditions for the production of plastic products. The high-gloss mold temperature machine is developed on the basis of the traditional mold temperature machine. The high-gloss mold temperature machine mainly consists of a heating system, a cooling system, a circulation pump, a temperature sensor, a control system, etc. Its working principle is to transport the heating or cooling medium to the flow channels inside the mold through the circulation pump, and conduct heat exchange with the mold to adjust the mold temperature.

[0003] Chinese Patent CN207971836U discloses a high-gloss machine with a vortex heat energy recovery function, including a high-gloss machine body. A water pump, a water storage bucket, a heating container, and a vortex heat energy recovery device are arranged inside the high-gloss machine body. The water pump is connected to the water storage bucket through a conveying pipeline. The water storage bucket is communicated with the heating container. A high-temperature steam outlet is arranged on the upper side wall of the heating container. The high-temperature steam outlet is connected to the mold to be processed through a conveying pipeline. The vortex heat energy recovery device is arranged at the upper end of the heating container and is communicated with the heating container. The vortex heat energy recovery device is connected to the mold through a high-temperature steam recovery channel.

[0004] During the use of the above technical solution, the high-temperature steam after heating the mold enters the vortex heat energy recovery device through the recovery pipeline, and is converted into high-temperature hot water and waste gas. The high-temperature hot water returns to the heating container, but the temperature of the high-temperature hot water is still lower than the temperature at which high-temperature water vapor can be generated inside the heating container. Therefore, directly introducing the high-temperature hot water with a large temperature difference in the vortex heat energy recovery device into the heating container actually plays a cooling role and instead reduces the working efficiency.

A temperature sensor two is provided inside the pipeline four 13. An inlet port five, an inlet port six, and an outlet port four are provided on the cooling water tank 4. The inlet port five is connected to the municipal water supply pipeline 6. The outlet port four is connected to an inlet port six on the mold 5 through a pipeline five 15.

[0025] In this embodiment, electronic control valves are provided on the inlet port one, the inlet port two, the inlet port three, the inlet port four, the inlet port five, the inlet port six, the outlet port one, the outlet port two, the outlet port three, and the outlet port four to control the flow rate.

[0027] In this embodiment, safety air valves are provided on the heat preservation water tank 1 and the heating water tank 2.

[0029] In this embodiment, a temperature sensor four and a temperature sensor five are respectively provided inside the heat preservation water tank 1 and the heating water tank 2 to detect the water temperature.

[0030] The working principle and beneficial effects of the above technical solution are as follows:

[0031] When in use, the preheating operation steps are as follows:

[0032] In the first step, first open the electric control valves and water pump 1 at the water inlet port 1, water inlet port 2, and water outlet port 1 through the controller, so that the water levels in the heat preservation water tank 1 and the heating water tank 2 reach the preset maximum water levels. The liquid level conditions are detected by the liquid level sensor and the detection data is transmitted to the controller in real time. In the second step, turn on the heating devices in the heat preservation water tank 1 and the heating water tank 2 to heat up to the preset temperature. In this embodiment, take the set temperature value in the heating water tank 2 as 90 °C and the set temperature value in the heat preservation water tank 1 as 50 °C as an example.

[0033] The heating process of the mold 5 is as follows: The controller controls the water pump 2 to transport the high-temperature hot water in the heating water tank 2 into the temperature adjustment water tank 3, and opens the electric control valve at the water inlet port as needed to add cold water to adjust the temperature of the temperature adjustment water tank 3 to reach the suitable working temperature. Then turn on the water pump 3 and use the hot water in the temperature adjustment water tank 3 to heat the mold 5. When the hot water coming out of the mold 5 passes through the pipeline 4, when the temperature sensor detects that the water temperature is higher than the water temperature in the heat preservation water tank 1, the controller controls the electric control distribution valve 1 to establish the connection between the pipeline 4 and the heating water tank 2. When the temperature sensor detects that the water temperature is lower than the water temperature in the heat preservation water tank 1, the controller controls the electric control distribution valve 1 to establish the connection between the pipeline 4 and the heat preservation water tank 1. An overflow pipe is provided in the heat preservation water tank 1. When the water temperature is higher than the overflow pipe, the excess water will be discharged and used as domestic hot water.

[0034] The cooling process of the mold 5 is as follows: Open the electric control valve at the water port 5 through the controller, inject the cooling water into the cooling water tank 4, and stop when it reaches the preset water level. Turn on the water pump 4 to inject the cold water into the mold 5 to cool the mold 5. The cooled water flows through the pipeline 6. When the temperature sensor 3 detects that the temperature is lower than the preset value, such as 30 °C, the electric control distribution valve 2 establishes the connection between the top of the cooling water tank 4 and the pipeline 6, so as to recycle the cooling water. When the temperature is higher than 30 °C, the electric control distribution valve 2 establishes the connection between the top of the heat preservation water tank 1 and the pipeline 6.

[0035] Compared with the prior art, the utility model performs hierarchical treatment on the hot water after passing through the mold 5, and according to the different temperatures, it flows to the heating water tank 2 and the heat preservation water tank 1, thereby ensuring the heating efficiency in the heating water tank 2. The heating device in the heat preservation water tank 1 of the utility model also has a preheating effect, further improving the heating efficiency. The water after cooling in the utility model is also subjected to hierarchical treatment, and according to the different temperatures, it flows to the cooling water tank 4 and the heat preservation water tank 1, which not only ensures the cooling efficiency but also achieves the effect of recycling and recovering heat energy, saving energy.

[0036] The above are only the preferred specific embodiments of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
