Description

Technical Field

[0001] This utility model belongs to the field of mold temperature controller technology, specifically an energy-saving mold temperature controller. Background Technology

[0002] Mold temperature controllers, also known as mold temperature control units, were initially used in the injection mold temperature control industry. Later, with the development of the machinery industry, their applications became increasingly widespread. Now, mold temperature controllers are generally divided into water temperature controllers and oil temperature controllers, with a temperature control accuracy of ±0.1℃. Mold temperature controllers are widely used in various industries such as plastic molding, die casting, rubber tires, rollers, chemical reaction vessels, bonding, and mixing. In a broader sense, they are temperature control equipment, encompassing both heating and cooling temperature control.

[0003] A mold temperature controller, as disclosed in CN216968409U, includes: a housing, a pressure pump, and a heating and distribution assembly; the pressure pump is installed inside the housing; the heating and distribution assembly includes a heater, an outlet pipe, an inlet pipe, a first pipe body, and a distribution component; the heater is installed in the housing and has a medium inlet, a medium outlet, and a heating chamber, which is connected to the medium inlet and the medium outlet respectively; one end of the inlet pipe extends into the heating chamber and connects to the heater, and the other end is connected to the pressure pump; one end of the outlet pipe extends into the heating chamber and connects to the heater, and the other end is connected to the distribution component; the distribution component is used to discharge or recover the temperature control medium; the distribution component is connected to the pressure pump through the first pipe body; the outlet pipe, the inlet pipe, and the heater are integrally formed; this utility model can reduce the possibility of corrosion inside the mold temperature controller, thereby increasing the service life of the mold temperature controller;

[0004] This mold temperature controller does not have any heat recovery mechanism, which results in high energy consumption for heating the mold. To solve the above problem, an energy-saving mold temperature controller is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the above problems by providing an energy-saving mold temperature controller, comprising:

[0006] The main housing has an oil tank fixedly installed at its upper interior. A heater is fixedly installed on one side of the main housing. An oil pump is fixedly installed on the lower inner wall of the main housing. The output end of the oil tank is fixedly connected to one side of the heater through an oil pipe. The output end of the heater is connected to the input end of the oil pump through an oil pipe.

[0007] A slide rail is fixedly installed inside the middle of the main housing. An electric slider is slidably connected to the outer wall of the slide rail. A connecting plate is fixedly installed at the bottom of the electric slider. Multiple fixing rings are fixedly installed on the outer wall of the connecting plate. A heat exchange tube is fixedly installed inside the fixing ring. The heat exchange tube is slidably connected to the outer wall of the heater.

[0008] With the above technical solution, when the mold needs to be heated, the oil pump operates to draw the heat transfer oil from the oil tank into the heater, which then heats the oil. The heated oil is then sent to the mold. When the temperature inside the mold is too high, cooling water is drained into the heat exchange tube, which exchanges heat with the heater, thus lowering the oil temperature. During the heat exchange process, the cooling water in the heat exchange tube is heated. At this point, the heat exchange tube is moved out of the heater's outer wall by an electric slider. When secondary heating is required, the heat exchange tube is simply moved back to the heater's outer wall. The hot water in the heat exchange tube then provides heat tracing for the heater, which not only improves heating efficiency but also reduces energy consumption.

[0009] In a preferred embodiment, an oil outlet pipe is fixedly installed at the output end of the oil pump, and a return oil pipe is fixedly installed at the input end of the heater.

[0010] Through the above technical solution, the oil pump sends the heated heat transfer oil to the mold, and the heat transfer oil after passing through the mold enters the heater through the return oil pipe for reheating.

[0011] In a preferred embodiment, a plurality of casters are fixedly mounted on the bottom of the main housing.

[0012] The above technical solution facilitates the movement of the equipment by installing casters.

[0013] In a preferred embodiment, an electric heating rod is fixedly installed inside the heater.

[0014] The above technical solution allows the electric heating rod to heat the heat-conducting oil inside the heater when energized.

[0015] In a preferred embodiment, corrugated pipes are fixedly installed at both ends of the heat exchange tube.

[0016] Through the above technical solution, a corrugated pipe is installed to allow the heat exchange tube to expand and contract during the movement of the heat exchange tube.

[0017] In a preferred embodiment, both the oil pump and the electric slider are controlled by a PLC.

[0018] In summary, due to the adoption of the above technical solutions, the beneficial effects of this utility model are: this utility model proposes an energy-saving mold temperature controller.

[0019] When the mold needs to be heated, the oil pump draws the heat transfer oil from the oil tank into the heater, which then heats the oil. The heated oil is then sent to the mold. When the temperature inside the mold is too high, cooling water is drained into the heat exchange tubes. The heat exchange tubes exchange heat with the heater, thus lowering the oil temperature. During the heat exchange process, the cooling water inside the heat exchange tubes is heated. At this point, the electric slider moves the heat exchange tubes out of the heater's outer wall. When secondary heating is required, the heat exchange tubes are simply moved back to the heater's outer wall. The hot water inside the heat exchange tubes then provides heat tracing for the heater, which not only improves heating efficiency but also reduces energy consumption. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] The following will combine Figure 1-3 A detailed description of an energy-saving mold temperature controller according to an embodiment of this utility model is provided.

[0026] Example:

[0027] An energy-saving mold temperature controller, comprising:

[0028] The main housing 1 has an oil tank 2 fixedly installed at its upper end and multiple casters 13 fixedly installed at the bottom of the main housing 1. The casters 13 facilitate the movement of the equipment. A heater 3 is fixedly installed on one side inside the main housing 1. An electric heating rod 14 is fixedly installed inside the heater 3. The electric heating rod 14 is energized to heat the heat transfer oil inside the heater 3.

[0029] An oil pump 4 is fixedly installed on the lower inner wall of the main housing 1. The output end of the oil tank 2 is fixedly connected to one side of the heater 3 through an oil pipe. The output end of the heater 3 is connected to the input end of the oil pump 4 through an oil pipe. An oil outlet pipe 10 is fixedly installed on the output end of the oil pump 4. An oil return pipe 11 is fixedly installed on the input end of the heater 3. The oil pump 4 sends the heated heat transfer oil to the mold. After passing through the mold, the heat transfer oil enters the heater 3 through the oil return pipe 11 for reheating. When the mold needs to be heated, the oil pump 4 works to draw the heat transfer oil in the oil tank 2 into the heater 3. The heater 3 heats the heat transfer oil, and the heated heat transfer oil is sent to the mold.

[0030] The slide rail 5 is fixedly installed inside the middle of the main housing 1. An electric slider 6 is slidably connected to the outer wall of the slide rail 5. Both the oil pump 4 and the electric slider 6 are controlled by a PLC. A connecting plate 7 is fixedly installed at the bottom of the electric slider 6. Multiple fixing rings 8 are fixedly installed on the outer wall of the connecting plate 7. A heat exchange tube 9 is fixedly installed inside the fixing rings 8. Corrugated pipes 12 are fixedly installed at both ends of the heat exchange tube 9. During the movement of the heat exchange tube 9, the corrugated pipes 12 allow it to expand and contract. The heat exchange tube 9 is slidably connected to the outer wall of the heater 3. When the temperature inside the mold is too high, cooling water is discharged into the heat exchange tube 9. The heat exchange tube 9 exchanges heat with the heater 3, thereby lowering the oil temperature. During the heat exchange process, the cooling water inside the heat exchange tube 9 is heated. At this time, the electric slider 6 drives the heat exchange tube 9 to move out of the outer wall of the heater 3. When secondary heating is required, the heat exchange tube 9 is simply moved back to the outer wall of the heater 3. At this time, the hot water inside the heat exchange tube 9 provides heat tracing for the heater, which not only improves the heating efficiency but also reduces the power consumption.

[0031] Working principle:

[0032] When the mold needs to be heated, the oil pump 4 operates to draw the heat transfer oil from the oil tank 2 into the heater 3. The heater 3 heats the heat transfer oil, and the heated oil is sent to the mold. When the temperature inside the mold is too high, cooling water is discharged into the heat exchange tube 9. The heat exchange tube 9 exchanges heat with the heater 3, thereby lowering the oil temperature. During the heat exchange process, the cooling water in the heat exchange tube 9 is heated. At this time, the electric slider 6 drives the heat exchange tube 9 to move out of the outer wall of the heater 3. When secondary heating is required, the heat exchange tube 9 is simply moved back to the outer wall of the heater 3. At this time, the hot water in the heat exchange tube 9 provides heat tracing for the heater, which not only improves the heating efficiency but also reduces the power consumption.
