Description

Technical Field

[0001] The utility model relates to the technical field of temperature control and adjustment equipment for injection molds, and particularly relates to a temperature control and adjustment device for injection molds. Background Technique

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. When processing products through an injection mold, it is often necessary to preheat the mold through a temperature control and adjustment device in advance. After injection molding, the temperature of the mold is then cooled down through the temperature control and adjustment device.

[0003] For example, in the utility model: "Temperature control device for injection molds", the publication number is: "CN207669722U". This patent drives the serpentine heat exchange tube to move upward through a lifting drive device, so that more straight parts of the serpentine heat exchange tube enter the heat exchange box, thereby increasing the heat exchange area, and then greatly increasing the temperature of the low-temperature cooling water in the heat exchange box. However, during the implementation of this patent, after cooling the injection mold, the water temperature rises, and the device cannot reuse the heat in the water, which is likely to cause heat waste, and it cannot cool and preheat different injection molds simultaneously. Therefore, the research and development of a new temperature control and adjustment device for injection molds has received more and more attention from researchers. Content of the Utility Model

Detailed Embodiment

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3, an embodiment provided by the present utility model: a temperature control and adjustment device for an injection mold, including a base 1, a water storage tank 2, a U-shaped plate 3, an injection mold preheating chamber 7, and an injection mold cooling chamber 11. Both ends of the top of the base 1 are provided with U-shaped plates 3, and a water storage tank 2 is installed at the middle position of the top of the base 1. One end of the top of the U-shaped plate 3 is provided with an injection mold preheating chamber 7, and one end of the top of the U-shaped plate 3 away from the injection mold preheating chamber 7 is provided with an injection mold cooling chamber 11. A cooling water pipe 20 is installed inside the injection mold cooling chamber 11, and a preheating water pipe 8 is installed inside the injection mold preheating chamber 7. A third diversion pipe 9 is installed on the outside of the cooling water pipe 20. The third diversion pipe 9 passes through the injection mold cooling chamber 11 and extends into the interior of the injection mold preheating chamber 7, and the end of the third diversion pipe 9 away from the cooling water pipe 20 is communicated with the preheating water pipe 8. An electric heating wire 10 is wound around the outside of the third diversion pipe 9. A cooling water pipe 16 is installed at the bottom of the U-shaped plate 3, and metal heat conduction blocks 17 are evenly installed at the bottom of the cooling water pipe 16. By means of the cooling water pipe 16 and the metal heat conduction blocks 17, the heat dissipation area is increased, so that the heat in the water can be quickly dissipated to the outside air, which is beneficial to quickly cooling the water. A water pump 12 is installed at the bottom inside the water storage tank 2. Here, the model of the water pump 12 can be ISGD. One end of the U-shaped plate 3 close to the injection mold preheating chamber 7 is provided with a control panel 4, and one end of the U-shaped plate 3 away from the control panel 4 is provided with an air extraction pump 19. Here, the model of the air extraction pump 19 can be VCH1028. The output end of the air extraction pump 19 is provided with a fifth diversion pipe 18, and the fifth diversion pipe 18 passes through the U-shaped plate 3. The output end of the control panel 4 is electrically connected to the input ends of the electric heating wire 10, the water pump 12, and the air extraction pump 19 through wires respectively. The output end of the water pump 12 is provided with a second diversion pipe 6. The second diversion pipe 6 passes through the water storage tank 2, and the end of the second diversion pipe 6 away from the water pump 12 is communicated with the cooling water pipe 16. The water pump 12 pumps the water inside the water storage tank 2 into the cooling water pipe 16 through the second diversion pipe 6.

[0022] As Figures 1-3As shown, a first diversion pipe 5 is installed outside the preheating water pipe 8, and the first diversion pipe 5 passes through the U-shaped plate 3 and extends into the interior of the water storage tank 2. A fourth diversion pipe 15 is installed outside the cooling water pipe 20. The fourth diversion pipe 15 passes through the U-shaped plate 3, and one end of the fourth diversion pipe 15 away from the cooling water pipe 20 is communicated with the cooling water pipe 16. Cold water enters the interior of the cooling water pipe 20 through the fourth diversion pipe 15, and heat exchange can be carried out between the cooling water pipe 20 and the injection mold, so that the heat on the injection mold is transferred to the water, thereby increasing the water temperature, and the injection mold in the injection mold cooling chamber 11 can be cooled. After the hot water enters the interior of the preheating water pipe 8 through the third diversion pipe 9, heat exchange can be carried out between the preheating water pipe 8 and the injection mold in the injection mold preheating chamber 7. Not only can the heat in the water be dissipated, reducing the water temperature, but also the injection mold in the injection mold preheating chamber 7 can be preheated. The water flows back into the interior of the water storage tank 2 through the first diversion pipe 5, and then the water is pumped into the interior of the cooling water pipe 16 by the water pump 12, enabling the water to circulate.

[0023] As Figures 1-3 shown, a heat dissipation air pipe 13 is installed at the top of the water storage tank 2. The heat dissipation air pipe 13 is communicated with the fifth diversion pipe 18, and nozzles 14 are uniformly installed at the top of the heat dissipation air pipe 13. During use, the air pump 19 pumps gas into the interior of the heat dissipation air pipe 13 through the fifth diversion pipe 18 and blows the gas uniformly to different positions of the cooling water pipe 16 through the nozzles 14, which is beneficial to quickly removing the heat on the cooling water pipe 16 and further improving the heat dissipation effect.

[0024] As Figure 1 shown, a water inlet pipe is installed at one end of the top of the water storage tank 2 away from the air pump 19, and a sealing pipe cap is installed at the top of the water inlet pipe, facilitating the addition of water into the interior of the water storage tank 2.

[0025] Working principle:

[0026] During use, an appropriate amount of cold water can be added into the interior of the water storage tank 2, and the device is powered on. The staff can simultaneously place the injection mold to be cooled in the injection mold cooling chamber 11 and place the injection mold to be preheated in the injection mold preheating chamber 7.

[0027] The staff can start the water pump 12 through the control panel 4. The water pump 12 pumps the cold water in the water storage tank 2 into the interior of the cooling water pipe 16 through the second diversion pipe 6. The cold water enters the interior of the cooling water pipe 20 through the fourth diversion pipe 15, and heat exchange can be carried out between the cooling water pipe 20 and the injection mold, so that the heat on the injection mold is transferred to the water, thereby increasing the water temperature, and the injection mold in the injection mold cooling chamber 11 can be cooled.

[0028] After the hot water enters the interior of the preheating water pipe 8 through the third diversion pipe 9, heat exchange can be carried out between the preheating water pipe 8 and the injection mold inside the preheating chamber 7 of the injection mold. This not only allows the heat in the water to dissipate, reducing the water temperature, but also preheats the injection mold inside the preheating chamber 7 of the injection mold.

[0029] The water flows back into the interior of the water storage tank 2 through the first diversion pipe 5, and then the water pump 12 pumps the water into the interior of the cooling water pipe 16, enabling the water to circulate.

[0030] After the water enters the interior of the cooling water pipe 16, the staff can start the air extraction pump 19 through the control panel 4. The air extraction pump 19 sucks the gas into the interior of the heat dissipation air pipe 13 through the fifth diversion pipe 18 and evenly blows the gas to different positions of the cooling water pipe 16 through the nozzle 14, which is conducive to quickly removing the heat on the cooling water pipe 16 and cooling the water.

[0031] If there is no injection mold to be cooled placed inside the injection mold cooling chamber 11 and there is an injection mold to be preheated placed inside the injection mold preheating chamber 7, when the water flows from the cooling water pipe 20 into the third diversion pipe 9, the water temperature is relatively low. The staff can start the electric heating wire 10 through the control panel 4. The electric heating wire 10 can heat the water, enabling the hot water to enter the interior of the preheating water pipe 8 through the third diversion pipe 9 and preheating the injection mold inside the preheating chamber 7 of the injection mold through the preheating water pipe 8.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
