Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to an oil tank embedded cooling device. Background Technology

[0002] Injection molding machines heat plastic and apply high pressure to the molten plastic, causing it to be ejected and fill the mold cavity. Most injection molding machines used today are hydraulic. During operation, hydraulic oil is drawn from the oil tank to provide power to the injection molding machine. However, hydraulic oil generates a lot of heat during operation and needs to be cooled.

[0003] In the prior art, a Chinese patent document (publication number: CN206085581U, patent name: a cooling system for an injection molding machine) discloses a solution that includes "an oil reservoir disposed outside the injection molding machine, the oil reservoir including a shell, a cylindrical oil tank inside the shell, an oil filter connected to the bottom of the oil tank, the oil filter connected to an oil outlet, and a cooling pipe wound around the outside of the oil tank; the cooling pipe is connected to a water tank and a water pump, which are connected in series to form a cooling water circulation mechanism; a temperature sensor is installed on the oil tank, and the temperature sensor is connected to a PLC control processor."

[0004] Based on the description and drawings in the patent document, the cooling pipe is wrapped around the outside of the oil tank. Cold water enters the cooling pipe through an external water tank and water pump. The temperature of the cold water is transferred to the injection molding oil tank through the cooling pipe, thereby cooling the hydraulic oil inside the oil tank during injection molding. However, the cooling effect of this cooling method is not good enough, and the water tank and the injection molding oil tank are separate entities, which occupy a large space. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art by providing an embedded cooling device in an oil tank, which increases the contact area between the high-temperature oil and the cooling device and improves the heat exchange efficiency of the cooling device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] An embedded cooling device for an oil tank includes a housing. The housing contains a first cavity and a second cavity. The first cavity is used to hold high-temperature oil that needs to be cooled, and the second cavity is used to hold low-temperature oil that has been cooled. A cooling component for cooling the high-temperature oil in the first cavity is provided on one side of the first cavity, and a partition for separating the second cavity is provided on the other side of the first cavity. The partition has a flow channel. The first cavity has an oil inlet, and the second cavity has an oil outlet. The high-temperature oil enters the first cavity through the oil inlet, and after contacting the cooling component to achieve cooling, it enters the second cavity through the flow channel and is discharged through the oil outlet.

[0008] Furthermore, the volume of the first cavity is smaller than the volume of the second cavity; the flow channel is strip-shaped and located near the top of the partition.

[0009] Furthermore, the cooling assembly includes a first connector and a second connector, which are connected by a cooling pipe. The first connector and the second connector are disposed on the outside of the housing, and the cooling pipe is disposed inside the first cavity.

[0010] Furthermore, the first connector is provided with a first flow channel, a plurality of first flow holes are provided on one side of the first flow channel, and a plurality of second flow holes are arranged on the other side of the first flow channel. The first flow holes, the first flow channel and the second flow holes are connected to each other.

[0011] Furthermore, the second connector is provided with a second flow channel, a plurality of third flow holes are provided on one side of the second flow channel, and a plurality of fourth flow holes are arranged on the other side of the third flow holes, and the third flow holes, the second flow channel and the fourth flow holes are connected to each other.

[0012] Furthermore, the first connector is provided with a first plug at its end, and the second connector is provided with a second plug at its end.

[0013] Furthermore, the housing is provided with a mounting plate, which is located on the side of the first cavity. A first mounting port is provided above the mounting plate, and a second mounting port is provided below the mounting plate. A first connector is provided on the first mounting port, and a second connector is provided on the second mounting port.

[0015] Furthermore, the oil outlet is fixed with an oil outlet pipe, which is connected to the second cavity.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] like Figures 1 to 5As shown, an embedded cooling device for an oil tank includes a housing 1, within which a first cavity 101 and a second cavity 102 are provided. The first cavity 101 is used to hold high-temperature oil that needs to be cooled, and the second cavity 102 is used to hold low-temperature oil after cooling. A cooling component 2 for cooling the high-temperature oil in the first cavity 101 is provided on one side of the first cavity 101. That is, the high-temperature oil introduced into the first cavity 101 exchanges heat with the cooling component 2 to form low-temperature oil before flowing into the second cavity 102. In this embodiment, the volume of the first cavity 101 is set to be smaller than the volume of the second cavity 102, that is, the high-temperature oil is cooled within a small volume range before being output, which helps to improve the heat exchange effect with the cooling component 2 and achieve a good cooling effect.

[0030] A partition 3 for separating the second cavity 102 is provided on the other side of the first cavity 101. The partition 3 is provided with a flow channel 301. The first cavity 101 is provided with an oil inlet 1011, and the second cavity 102 is provided with an oil outlet 1021. High-temperature oil enters the first cavity 101 through the oil inlet 1011 and comes into contact with the cooling component 2 to achieve cooling. The cooled oil enters the second cavity 102 through the flow channel 301 and is finally discharged from the oil outlet 1021. This arrangement allows the high-temperature oil to come into direct contact with the cooling component 2, increasing the contact area between the high-temperature oil and the cooling device, while improving the heat exchange efficiency of the cooling device, thereby achieving a better cooling effect on the high-temperature oil. Furthermore, the combination of the housing 1 and the cooling component 2 makes the cooling device structure more compact and occupies less space.

[0031] Specifically, such as Figures 2 to 8 As shown, in this embodiment, the flow channel 301 is strip-shaped and located near the top of the partition 3. The flow channel 301 is arranged horizontally to ensure that the high-temperature oil is cooled and raised to a certain height in the first cavity 101 before flowing away through the flow channel 301. The high-temperature oil level in the first cavity 101 will rise gradually as the oil level increases. During the rising process, the high-temperature oil will pass through the cooling component 2 to exchange heat and achieve cooling. When the oil rises to the corresponding height and corresponds to the flow channel 301, the oil that has been cooled will enter the second cavity 102 from the flow channel 301.

[0032] The cooling assembly 2 includes a first connector 201 and a second connector 202, which are connected by a cooling pipe 6. The first connector 201 and the second connector 202 are located on the outside of the housing 1, and the cooling pipe 6 is located inside the first cavity 101 to facilitate heat exchange with the high-temperature oil in the first cavity 101. The coolant enters the cooling pipe 6 from the first connector 201, and the temperature of the coolant is transferred to the high-temperature oil through the cooling pipe 6 to achieve heat exchange. Finally, it is discharged from the second connector 202.

[0033] The housing 1 is provided with a mounting plate 104, which is located on the side of the first cavity 101. A first mounting port 105 is provided above the mounting plate 104, and a second mounting port 103 is provided below the mounting plate 104. A first connector 201 is correspondingly provided on the first mounting port 105, and a second connector 202 is correspondingly provided on the second mounting port 103.

[0034] The first connector 201 has a first flow channel 2011. A plurality of first flow holes 2012 are provided on one side of the first flow channel 2011, and a plurality of second flow holes 2013 are arranged on the other side of the first flow channel 2011. The first flow holes 2012, the first flow channel 2011, and the second flow holes 2013 are connected. The second connector 202 has a second flow channel 2021. A plurality of third flow holes 2022 are provided on one side of the second flow channel 2021, and a plurality of fourth flow holes 2023 are arranged on the other side of the third flow holes 2022. The third flow holes 2022, the second flow channel 2021, and the fourth flow holes 2023 are connected. The cooling pipe 6 is connected at one end to the second flow hole 2013 and at the other end to the fourth flow hole 2023. The number of second and fourth flow holes 2013 is set to allow multiple cooling pipes 6 to be connected, so as to achieve a better cooling effect on high-temperature oil. The coolant enters the first flow channel 2011 from the first flow hole 2012 located on the outside of the first connector 201, and then flows into the cooling pipe 6 from the second flow hole 2013 located on the inside. It exchanges heat with the first cavity 101 in the cooling pipe 6, and then enters the second flow channel 2021 through the fourth flow hole 2023 located on the inside of the second connector 202, and finally flows out from the third flow hole 2022.

[0035] The first connector 201 has a first plug 2014 at its end, which seals the end of the first connector 201 to ensure that oil entering the first flow channel 2011 is discharged from the second flow hole 2013. The second connector 202 has a second plug 2024 at its end, which seals the end of the second connector 202 to ensure that oil entering the second flow channel 2021 is discharged from the third flow hole 2022. In fact, both the first and second flow channels 2011 and 2021 are drilled along their length, resulting in openings on the sides. The first and second plugs 2014 and 2024 are used to seal these openings to prevent leakage. This can be achieved by creating internal threads at the openings and external threads on the first and second plugs 2014 and 2024, thus securing them via a threaded connection.

[0036] An oil inlet pipe 4 is fixed in the oil inlet 1011. The oil inlet pipe 4 is connected to the first cavity 101. High-temperature oil enters the first cavity 101 through the oil inlet pipe 4. The oil inlet pipe 4 extends downward and is close to the bottom of the box 1, so that the high-temperature oil enters from the bottom, is cooled, and gradually rises to the flow channel 301 and then flows through the second cavity 102. This helps to increase the residence time of the high-temperature oil in the first cavity 101.

[0037] An oil outlet pipe 5 is fixed in the oil outlet 1021. The oil outlet pipe 5 is connected to the second cavity 102. The cooled low-temperature oil in the second cavity 102 is discharged to the external working equipment through the oil outlet pipe 5. After working, the low-temperature oil will be heated to high-temperature oil and then enter the first cavity 101 through the oil inlet pipe 4 for cooling. This cycle continues.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
