Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature equipment, in particular to a biodegradable injection molding constant temperature equipment. Background Art

[0002] Biodegradable materials refer to materials that can gradually degrade under natural environmental conditions through the action of biological factors such as microorganisms and enzymes. Compared with traditional plastics, biodegradable materials have a lower risk of environmental pollution. Injection molding constant temperature equipment, also known as mold temperature controllers, is a device that provides temperature control. In industries such as plastic molding, mold temperature controllers improve product quality and production efficiency by controlling mold temperature.

[0003] A search revealed a Chinese patent with publication number CN220517475U, which discloses a constant temperature device for biodegradable material injection molding. The device comprises a mold temperature controller, a left side plate, and a support assembly. The left side plate is provided with at least four groups of first mounting holes, wherein first mounting tubes are mounted on the inner walls of the first mounting holes, a first mounting bracket is mounted on the inner wall of the first mounting tubes, a first motor is mounted on the outer wall of the first mounting bracket, a first housing is mounted on the output end of the first motor, and an air intake fan is mounted on the outer wall of the first housing.

[0004] In the above technology, although the cooling speed of the constant temperature device is accelerated by the design of the air intake fan blades and the exhaust fan blades, since the constant temperature device controls the temperature of the medium such as water or oil during use, and thus adjusts the temperature of the mold, when the mold needs to be cooled, the medium needs to be cooled. Usually, a cooling box is provided in the constant temperature device, and a cooling pipe is provided inside the cooling box. When cooling, external cooling water needs to be injected into the cooling pipe to cool the medium in the cooling box. However, after the cooling water absorbs the heat of the medium, its own temperature will increase. If the cooling water with increased temperature is not cooled, the subsequent cooling effect on the medium will be affected. The air intake fan blades and the exhaust fan blades provided in the above technology can only directly cool the cooling box, so that the medium in the middle of the cooling box is difficult to cool down quickly, thereby affecting the subsequent control of the mold temperature.

[0005] To this end, the utility model provides a biodegradable injection molding constant temperature device. Utility Model Content

[0016] The utility model uses a water pump to transport the cooling water in the water tank to the cooling pipe, thereby cooling the oil in the cooling box. In this process, the temperature of the cooling water will increase. Therefore, the design of the heat dissipation pipe can dissipate heat and cool the cooling water with increased temperature, so that the cooling water has a better cooling effect in subsequent cooling operations. By arranging fins on the heat dissipation pipe, the heat dissipation area can be increased and the efficiency of heat transfer can be improved. At the same time, the forced convection generated by the fan can significantly speed up the speed of heat transfer from the heat dissipation pipe to the surrounding environment, thereby speeding up the cooling water cooling speed. At the same time, by arranging the water tank inside the chassis, the constant temperature device does not need to be connected to the cooling water, which makes it easier for the constant temperature device to be moved and used by people.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figure 1-6 The utility model provides a technical solution: a biodegradable injection molding constant temperature device, comprising a chassis 1, the interior of the chassis 1 is divided into a first chamber 2 and a second chamber 3 by a partition 29, one end of the top of the first chamber 2 is fixedly connected to an oil tank 4, a cooling box 5 is connected below the oil tank 4, an oil pump 6 is provided below the cooling box 5, an input end of the oil pump 6 is connected to the cooling box 5, a cooling pipe 7 is provided inside the cooling box 5, one end of the second chamber 3 is fixedly connected to a water tank 8, one end of the cooling pipe 7 is connected to the water tank 8, one end of the top of the water tank 8 is connected to a water pump 9, an output end of the water pump 9 is connected to a heat pipe 10, the heat pipe 10 is connected to the cooling pipe 7, a plurality of fins 11 are fixedly connected to the side wall of the heat pipe 10, and the water tank 8 is located adjacent to the heat pipe 10 and is fixedly connected to a fan 12;

[0026] In this embodiment, during the injection molding process, when the mold needs to be cooled, the temperature of the oil needs to be lowered and delivered to the flow channel in the mold through the oil pump 6, so as to achieve the cooling of the mold. During operation, the water pump 9 is first turned on. Under the action of the water pump 9, the cooling water in the water tank 8 will flow into the cooling pipe 7 in the cooling box 5. At this time, the cooling water in the cooling pipe 7 can absorb the temperature of the oil in the cooling box 5, thereby achieving the cooling of the oil. After absorbing the temperature of the oil, the temperature of the cooling water itself will increase. In order to facilitate the subsequent cooling operation, the cooling water has In order to achieve a better cooling effect, it is necessary to dissipate the heat and cool the cooling water with increased temperature. During operation, when the cooling water absorbs the temperature of the oil in the cooling pipe 7, it will flow into the heat dissipation pipe 10. At this time, the fan 12 is turned on. The forced convection generated by the fan 12 can significantly accelerate the speed of heat transfer from the heat dissipation pipe 10 to the surrounding environment. The fins 11 provided on the heat dissipation pipe 10 can increase the heat exchange area, thereby further accelerating the heat dissipation speed, thereby ensuring the cooling effect of the cooling water. In addition, multiple heat dissipation holes are provided on the side walls at both ends of the chassis 1 to facilitate heat dissipation.

[0027] The cooling pipe 7 is connected to the water tank 8 through the first connecting pipe 13, the cooling pipe 7 is connected to the heat dissipation pipe 10 through the second connecting pipe 14, the water tank 8 is connected to the input end of the water pump 9 through the third connecting pipe 15, and the output end of the water pump 9 is connected to the heat dissipation pipe 10 through the fourth connecting pipe 16;

[0028] In this embodiment, the design of the first connecting pipe 13, the second connecting pipe 14, the third connecting pipe 15 and the fourth connecting pipe 16 allows the water tank 8, the water pump 9, the cooling pipe 7 and the heat dissipation pipe 10 to be connected together, thereby facilitating the circulation of cooling water.

[0029] A heating tank 17 is fixedly connected to one end of the first chamber 2 away from the oil pump 6, and a heating rod 18 is fixedly connected to one end of the inner wall of the heating tank 17;

[0030] In this embodiment, during the injection molding process, it is sometimes necessary to improve the temperature of the mold. Therefore, the temperature of the oil is heated by designing the heating tank 17 and the heating rod 18, and the oil in the heating tank 17 is transported to the flow channel of the mold through the oil pump 6, thereby increasing the temperature of the mold.

[0031] The top of the heating tank 17 is connected to a first oil guide pipe 19, and the oil tank 4 is connected to the first oil guide pipe 19. One end of the bottom of the heating tank 17 is connected to a second oil guide pipe 20, and the second oil guide pipe 20 is connected to the input end of the oil pump 6.

[0032] In this embodiment, the design of the first oil conduit 19 and the second oil conduit 20 allows the heating tank 17 to be smoothly connected to the oil tank 4 and the input end of the oil pump 6 .

[0033] One end of the top of the cooling box 5 is connected to a third oil guide pipe 21, which is connected to the oil tank 4. One end of the bottom of the cooling box 5 is connected to a fourth oil guide pipe 22, which is connected to the input end of the oil pump 6.

[0034] In this embodiment, the design of the third oil conduit 21 and the fourth oil conduit 22 allows the cooling box 5 to be smoothly connected to the oil tank 4 and the input end of the oil pump 6 .

[0035] An electric valve 23 is installed at one end of the first oil guide pipe 19, the second oil guide pipe 20, the third oil guide pipe 21 and the fourth oil guide pipe 22;

[0036] In this embodiment, the design of the electric valve 23 makes it easier for the staff to control the flow path of the oil. When the mold temperature needs to be lowered, the electric valves 23 on the first oil guide pipe 19 and the second oil guide pipe 20 are closed, so that the oil in the oil tank 4 can only flow into the oil pump 6 through the cooling box 5. When the temperature of the mold needs to be increased, the electric valves 23 on the third oil guide pipe 21 and the fourth oil guide pipe 22 are closed, so that the oil in the oil tank 4 can only enter the oil pump 6 through the heating tank 17. The electric valve 23 is usually composed of an electric actuator and a valve. When in use, electric energy is used as power to drive the valve through the electric actuator to realize the opening and closing action of the valve.

[0037] The input end of the oil pump 6 is connected to a tee pipe 24, and the second oil guide pipe 20 and the fourth oil guide pipe 22 are both connected to the tee pipe 24. The output end of the oil pump 6 is connected to an oil outlet pipe 25, one end of which passes through the second chamber 3 and extends to the outside of the chassis 1;

[0038] In this embodiment, the design of the three-way pipe 24 allows the second oil guide pipe 20 and the fourth oil guide pipe 22 to be smoothly connected to the input end of the oil pump 6, and the design of the oil outlet pipe 25 allows the output end of the oil pump 6 to be smoothly connected to the mold flow channel, thereby facilitating the delivery of oil to the mold flow channel.

[0039] One end of the oil tank 4 is connected to an oil return pipe 26, one end of the oil return pipe 26 passes through the second chamber 3 and extends to the outside of the chassis 1. A temperature sensor 27 is installed at one end of the oil return pipe 26, and a controller 28 is installed at one end of the outer wall of the chassis 1;

[0040] In this embodiment, the oil return pipe 26 is designed to allow the oil in the mold flow channel to flow back into the oil tank 4. The temperature sensor 27 can sense the temperature of the oil during the oil flow process, thereby understanding the mold temperature. The controller 28 is used to control the electric valve 23, water pump 9, oil pump 6, heating rod 18 and fan 12 in the chassis 1.

[0041] Working principle: When in use, first connect the oil outlet pipe 25 and the oil return pipe 26 to the flow channel on the mold. When the mold needs to be cooled, the electric valve 23 on the first oil guide pipe 19 and the second oil guide pipe 20 is closed, and the oil pump 6 is opened at the same time. Under the action of the oil pump 6, the oil in the oil tank 4 will flow into the cooling box 5 and flow into the flow channel of the mold through the oil delivery pipe, thereby achieving cooling of the mold. In order to make the oil have a better cooling effect, it is necessary to cool the oil in the cooling box 5. During operation, turn on the water pump 9 first. Under the action of the water pump 9, the cooling water in the water tank 8 will flow into the cooling pipe 7 in the cooling box 5. At this time, the cooling water in the cooling pipe 7 can absorb the temperature of the oil in the cooling box 5, thereby achieving cooling of the oil. After absorbing the temperature of the oil, the temperature of the cooling water itself will increase. In order to facilitate the subsequent cooling operation, the cooling water has a better cooling effect, so it is necessary to increase the temperature. The cooling water with a certain temperature is used to dissipate heat and cool down the mold. During operation, when the cooling water absorbs the temperature of the oil in the cooling pipe 7, it will flow into the heat dissipation pipe 10. At this time, the fan 12 is turned on. The forced convection generated by the fan 12 can significantly accelerate the speed of heat transfer from the heat dissipation pipe 10 to the surrounding environment. The fins 11 provided on the heat dissipation pipe 10 can increase the heat exchange area, thereby further accelerating the heat dissipation speed, thereby ensuring the cooling effect of the cooling water. The oil in the mold flow channel will flow back to the oil tank 4 through the return oil pipe 26. When the temperature of the mold needs to be heated, the electric valve 23 on the third oil guide pipe 21 and the fourth oil guide pipe 22 is closed, and the electric valve 23 on the first oil guide pipe 19 and the second oil guide pipe 20 is opened at the same time. At this time, the oil in the oil tank 4 will flow into the heating tank 17. At this time, the heating rod 18 is turned on. Under the action of the heating rod 18, the oil can be heated, thereby achieving heating of the mold.

[0042] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to these embodiments without departing from the principles of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
