Abstract
Description
Technical Field
[0001] This utility model belongs to the field of injection molds and relates to a rapid cooling device for mold temperature controllers. Background Technology
[0002] During production, a mold temperature controller is used to heat the mold. The equipment operates in accordance with relevant technical standards. However, when the machine is shut down for cooling, it automatically shuts down when the temperature of the heat transfer oil drops below 100 degrees Celsius, according to the requirements of the heat transfer oil and the equipment. Even with all cooling devices turned on and the cooling dampers open, it takes at least 5 hours to cool down from the normal shutdown temperature of 200 degrees Celsius to the automatic shutdown temperature. After shutdown, someone needs to be on-site to supervise the machine and close all switches and valves after automatic shutdown. This wastes both energy (electricity) and manpower, and the excessively long waiting time is also detrimental to production. Based on this situation, the equipment has been improved to accelerate the cooling speed. Utility Model Content
[0003] The purpose of this invention is to provide a rapid cooling device for a mold temperature controller. By setting up an additional oil storage tank next to the mold temperature controller, the heat transfer oil stored in the oil storage tank that has been cooled to room temperature is replaced in the mold temperature controller and the mold, removing the residual heat from the mold and the mold temperature controller. The heat transfer oil that was originally around 200°C is replaced in the oil storage tank and mixed with the cooled heat transfer oil, so that the mold and the mold temperature controller can be cooled down rapidly, which is convenient for subsequent mold replacement or maintenance.
[0004] The technical solution adopted in this utility model is as follows:
[0005] A rapid cooling device for a mold temperature controller includes an oil storage tank, a mold temperature controller, and a mold plate. The mold temperature controller and the mold plate are connected by a circulating oil inlet pipe and a circulating oil outlet pipe to achieve hot oil circulation in the mold plate. The oil storage tank is located next to the mold temperature controller. The oil storage tank is connected to the circulating oil inlet pipe through an oil storage inlet pipe and to the circulating oil outlet pipe through an oil storage outlet pipe. An oil inlet valve is provided on the oil storage inlet pipe, and an oil outlet valve is provided on the oil storage outlet pipe.
[0006] Furthermore, the mold temperature controller heats the heat transfer oil to 200°C and then inputs the hot oil into the mold through the circulating oil inlet pipe, thereby realizing the circulation of the heat transfer oil.
[0007] Furthermore, the capacity of the oil storage tank is greater than or equal to the capacity of the mold temperature controller and the heat transfer oil in the mold.
[0008] Furthermore, the capacity of the oil storage tank is 1 cubic meter.
[0009] Furthermore, the oil storage tank is equipped with an exhaust valve at the top and a vent valve at the bottom.
[0010] Furthermore, the vent valve is located at the lowest point of the oil storage tank.
[0011] Furthermore, the oil storage tank is surrounded by an insulation layer, and a protective frame is installed outside the insulation layer to separate the oil storage tank and prevent personnel from contacting it.
[0012] Furthermore, both the inlet valve and the outlet valve are electromagnetic check valves, with the inlet valve directing the flow into the oil storage tank and the outlet valve directing the flow into the oil storage tank.
[0013] Furthermore, the oil storage tank is connected to the oil outlet pipe and the oil inlet pipe using a DN32 tank-specific flange, and the tank sealing standard is consistent with the mold temperature controller sealing standard.
[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0015] 1. A rapid cooling device for a mold temperature controller, wherein an additional oil storage tank is installed next to the mold temperature controller, so that the heat transfer oil stored in the oil storage tank that has been cooled to room temperature is replaced in the mold temperature controller and the mold, thereby removing the residual heat from the mold and the mold temperature controller, and the heat transfer oil originally at about 200°C is replaced in the oil storage tank and mixed with the cooled heat transfer oil, so that the mold and the mold temperature controller can be rapidly cooled, which facilitates subsequent mold replacement or maintenance.
[0016] 2. In this utility model, the oil storage tank is insulated to a certain extent. After the mold is reinstalled, the heat transfer oil in the oil storage tank still has a high temperature. Reheating can save energy, reduce heating time, and enable production to be resumed in a timely manner. Attached Figure Description

[0025] Example 1
[0026] This utility model provides a preferred embodiment of a rapid cooling device for a mold temperature controller, which includes an oil storage tank 1, a mold temperature controller 2, and a mold plate 3. The mold temperature controller 2 and the mold plate 3 are connected by a circulating oil inlet pipe 4 and a circulating oil outlet pipe 5 to achieve hot oil circulation in the mold plate 3. The oil storage tank 1 is located next to the mold temperature controller 2. The oil storage tank 1 is connected to the circulating oil inlet pipe 4 through an oil storage inlet pipe 6 and to the circulating oil outlet pipe 5 through an oil storage outlet pipe 7. An oil inlet valve 8 is provided on the oil storage inlet pipe 6, and an oil outlet valve 9 is provided on the oil storage outlet pipe 7. This structure can achieve overall circulation. Of course, the mold temperature controller 2 and the mold itself also have valves. When necessary, the valves between the mold temperature controller 2 and the mold, together with the oil inlet valve 8 and the oil outlet valve 9, can be used to completely replace the heat transfer oil in the mold temperature controller 2 and the mold.
[0027] The mold temperature controller 2 heats the heat transfer oil to 200°C and then inputs the hot oil into the mold plate 3 through the circulating oil inlet pipe 4, thereby realizing the circulation of the heat transfer oil.
[0028] The capacity of the oil storage tank 1 is greater than or equal to the capacity of the heat transfer oil in the mold temperature controller 2 and the mold plate 3, so as to quickly cool down to below 100°C and shut down the mold temperature controller 2. The capacity of the oil storage tank 1 is 1 cubic meter. Of course, this capacity is only a suitable capacity, which is a capacity that matches most mold temperature controllers 2. The capacity can be increased when necessary.
[0029] The oil storage tank 1 is equipped with an exhaust valve 10 at the top and a vent valve 11 at the bottom. The exhaust valve 10 is mainly used to discharge air, and the vent valve 11 is mainly used to drain the heat transfer oil in the oil storage tank 1. By using the vent valve 11, the heat transfer oil in the oil storage tank 1 can be completely drained. Therefore, by using this principle, the original heat transfer oil in the oil storage tank 1 can be drained and new heat transfer oil can be injected. With the opening and closing of each valve, the heat transfer oil inside the mold temperature controller 2 can be replaced, which is more convenient than directly replacing the heat transfer oil in the mold temperature controller 2.
[0030] The vent valve 11 is located at the lowest point of the oil storage tank 1, which facilitates the venting of the heat transfer oil.
[0031] The oil storage tank 1 is surrounded by an insulation layer 12. A protective frame 13 is set outside the insulation layer to separate the oil storage tank 1 from personnel contact, which has a certain heat preservation effect. At the same time, the protective frame 13 is set to prevent the oil storage tank 1 from being impacted and personnel from directly touching the oil storage tank 1, and to prevent the high-temperature heat transfer oil from causing danger to personnel.
[0032] Both the inlet valve 8 and the outlet valve 9 are electromagnetic check valves. The inlet valve 8 flows into the oil storage tank 1, and the outlet valve 9 flows into the oil storage tank 1. The unidirectional flow facilitates the circulation of the heat transfer oil. The use of electromagnetic valves makes operation easier and prevents the valves from being heated by the heat transfer oil, which could lead to danger for personnel.
[0033] When the oil storage tank 1 is connected to the oil outlet pipe 7 and the oil inlet pipe 6, a DN32 special flange for the storage tank is used. The sealing standard of the storage tank is consistent with the sealing standard of the mold temperature controller 2. Of course, a higher standard can also be used to avoid danger.
[0034] Example 2
[0035] A rapid cooling device for a mold temperature controller includes an oil storage tank 1, a mold temperature controller 2, and a mold plate 3. The mold temperature controller 2 and the mold plate 3 are connected by a circulating oil inlet pipe 4 and a circulating oil outlet pipe 5 to achieve hot oil circulation in the mold plate 3. The oil storage tank 1 is located next to the mold temperature controller 2. The oil storage tank 1 is connected to the circulating oil inlet pipe 4 through an oil storage inlet pipe 6 and to the circulating oil outlet pipe 5 through an oil storage outlet pipe 7. An oil inlet valve 8 is provided on the oil storage inlet pipe 6, and an oil outlet valve 9 is provided on the oil storage outlet pipe 7. This structure can achieve overall circulation. Of course, the mold temperature controller 2 and the mold itself also have valves. When necessary, the valves between the mold temperature controller 2 and the mold, in conjunction with the oil inlet valve 8 and the oil outlet valve 9, can be used to completely replace the heat transfer oil in the mold temperature controller 2 and the mold.
[0036] The mold temperature controller 2 heats the heat transfer oil to 200°C and then inputs the hot oil into the mold plate 3 through the circulating oil inlet pipe 4, thereby realizing the circulation of the heat transfer oil.
[0037] The capacity of the oil storage tank 1 is greater than or equal to the capacity of the heat transfer oil in the mold temperature controller 2 and the mold plate 3, so as to quickly cool down to below 100°C and shut down the mold temperature controller 2. The capacity of the oil storage tank 1 is 1 cubic meter. Of course, this capacity is only a suitable capacity, which is a capacity that matches most mold temperature controllers 2. The capacity can be increased when necessary.
[0038] The oil storage tank 1 is equipped with an exhaust valve 10 at the top and a vent valve 11 at the bottom. The exhaust valve 10 is mainly used to discharge air, and the vent valve 11 is mainly used to drain the heat transfer oil in the oil storage tank 1. By using the vent valve 11, the heat transfer oil in the oil storage tank 1 can be completely drained. Therefore, by using this principle, the original heat transfer oil in the oil storage tank 1 can be drained and new heat transfer oil can be injected. With the opening and closing of each valve, the heat transfer oil inside the mold temperature controller 2 can be replaced, which is more convenient than directly replacing the heat transfer oil in the mold temperature controller 2.
[0039] The vent valve 11 is located at the lowest point of the oil storage tank 1, which facilitates the venting of the heat transfer oil.
[0040] The oil storage tank 1 is surrounded by an insulation layer 12. A protective frame 13 is set outside the insulation layer to separate the oil storage tank 1 from personnel contact, which has a certain heat preservation effect. At the same time, the protective frame 13 is set to prevent the oil storage tank 1 from being impacted and personnel from directly touching the oil storage tank 1, and to prevent the high-temperature heat transfer oil from causing danger to personnel.
[0041] Both the inlet valve 8 and the outlet valve 9 are electromagnetic check valves. The inlet valve 8 flows into the oil storage tank 1, and the outlet valve 9 flows into the oil storage tank 1. The unidirectional flow facilitates the circulation of the heat transfer oil. The use of electromagnetic valves makes operation easier and prevents the valves from being heated by the heat transfer oil, which could lead to danger for personnel.
[0042] When the oil storage tank 1 is connected to the oil outlet pipe 7 and the oil inlet pipe 6, a DN32 special flange for the storage tank is used. The sealing standard of the storage tank is consistent with the sealing standard of the mold temperature controller 2. Of course, a higher standard can also be used to avoid danger.
[0043] A second oil storage tank is also provided, which is connected to the oil inlet pipe 6. The oil storage tank in Embodiment 1 is connected to the oil outlet pipe 7. The second oil storage tank is kept empty, so that most of the discharged high-temperature heat transfer oil is stored in the second oil storage tank. At this time, the temperature can be cooled down faster. When injecting heat transfer oil into the mold temperature controller and the mold, the high-temperature oil in the second oil storage tank can be introduced first, which can cool down and heat up faster. It is especially suitable for cases with a large amount of heat transfer oil. The principle is relatively simple and will not be shown in the figure.
[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions and improvements made by those skilled in the art within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
