Description

Technical Field

[0001] This utility model relates to the technical field of mold temperature control equipment, specifically a cold and hot integrated mold temperature control device. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain the desired products through injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. When producing automotive parts, raw materials need to be placed inside the mold, and the mold temperature is cooled by a mold temperature control device, so that the raw materials can be adjusted to the specified temperature for processing.

[0003] Utility model patent CN212859699U discloses a heating and cooling integrated mold temperature control device. This patent features a cover plate directly installed at the bottom of the mold, eliminating the need for flow channels within the mold and significantly reducing mold costs. It utilizes heat-conducting pillars and heat-conducting oil to achieve heat dissipation or heating between the cover plate and the mold, resulting in good temperature control uniformity. However, in practice, the single cooling water coil is close to multiple heat-conducting pillars, leading to a small contact area and heat exchange area. This hinders rapid heating or cooling of the heat-conducting pillars, significantly reducing the device's heating and cooling efficiency. Therefore, a novel heating and cooling integrated mold temperature control device is urgently needed to address these issues. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3This utility model provides an embodiment of a heating and cooling integrated mold temperature control device, comprising a heating chamber 7, a metal base plate 8, and a heat dissipation chamber 17. The heating chamber 7 is mounted on the top of the heat dissipation chamber 17, and the metal base plate 8 is mounted on the top of the heating chamber 7. A guide pipe 9 is installed inside the metal base plate 8. Mounting holes are provided at both ends of the top of the metal base plate 8 to facilitate installation of the metal base plate 8 with the mold. Metal heat-conducting pillars 12 are evenly installed on the bottom of the metal base plate 8, and a liquid pump 20 (ISGD type) is installed at one end of the bottom of the metal base plate 8. A diversion chamber 14 is installed inside the metal base plate 8 near the end of the liquid pump 20. A heat dissipation pipe 3 is installed on the top of the heat dissipation chamber 17, and an air pump 2 is installed at the end of the heat dissipation chamber 17 away from the liquid pump 20. The vacuum pump 2 can be a VCH1028. The output end of the vacuum pump 2 is equipped with a duct 1 that extends into the heat dissipation chamber 17. A return pipe 4 is installed at the bottom of the duct 9. The return pipe 4 passes through the metal base plate 8, and the end of the return pipe 4 away from the duct 9 is connected to the heat dissipation pipe 3. An electric heating wire 5 is wound around the outside of the return pipe 4. A control panel 6 is installed on the top of the end of the heat dissipation chamber 7 away from the liquid pump 20. The output end of the control panel 6 is electrically connected to the input end of the vacuum pump 2, the electric heating wire 5 and the liquid pump 20 respectively through wires. Heating tubes 11 are wound around the outside of the metal heat-conducting columns 12. An air outlet 18 is provided at the end of the heat dissipation chamber 17 away from the vacuum pump 2, and a dustproof net is installed inside the air outlet 18. The hot air inside the heat dissipation chamber 17 can be discharged through the air outlet 18.

[0022] like Figure 1 As shown, the end of the diversion chamber 14 away from the liquid pump 20 is uniformly equipped with second connecting pipes 13, and the end of the second connecting pipes 13 away from the diversion chamber 14 is connected to the heating pipe 11. The top of the heating pipe 11 is equipped with a first connecting pipe 10, which passes through the metal base plate 8. The end of the first connecting pipe 10 away from the heating pipe 11 is connected to the guide pipe 9. The oil is diverted through the diversion chamber 14 to the interior of multiple sets of second connecting pipes 13, and can also be diverted through the second connecting pipes 13 to the interior of multiple sets of heating pipes 11. The oil inside the heating pipe 11 then enters the interior of the guide pipe 9 through the first connecting pipe 10, and can be used to heat or cool the metal base plate 8 again through the guide pipe 9.

[0023] like Figure 1 As shown, the input end of the pump 20 is equipped with a pumping pipe 21, which passes through the heat dissipation chamber 17. The end of the pumping pipe 21 away from the pump 20 is connected to the heat dissipation pipe 3. The output end of the pump 20 is equipped with an outlet pipe 19 that extends into the distribution chamber 14. The pump 20 draws out the oil from inside the heat dissipation pipe 3 through the pumping pipe 21 and draws the oil into the distribution chamber 14 through the outlet pipe 19, which allows the oil to circulate.

[0024] like Figure 1As shown, a diversion pipe 16 is installed at the bottom inside the heat dissipation chamber 17. The diversion pipe 16 is connected to the air guide pipe 1, and nozzles 15 are evenly installed on the top of the diversion pipe 16. During the cooling process, the air pump 2 draws cold air from the outside into the diversion pipe 16 through the air guide pipe 1, and blows the cold air evenly to different positions of the heat dissipation pipe 3 through the nozzles 15, which can dissipate heat from the heat dissipation pipe 3, so that the heat is quickly dissipated, which is beneficial to improving the heat dissipation efficiency.

[0025] Working principle:

[0026] When in use, the device is connected to the power supply, and the mold can be installed above the metal base plate 8. When the mold needs to be heated, the operator can start the electric heating wire 5 and the liquid pump 20 through the control panel 6. The liquid pump 20 draws the oil inside the heat dissipation pipe 3 into the diversion chamber 14. The oil is diverted through the diversion chamber 14 to multiple sets of second connecting pipes 13, and can be diverted through the second connecting pipes 13 to multiple sets of heating pipes 11. The heating pipes 11 can then heat the metal heat-conducting column 12. The contact area between the heating pipes 11 and the metal heat-conducting column 12 is large, and the heat transfer efficiency is high. The metal heat-conducting column 12 transfers heat to the metal base plate 8, and the mold can be heated through the metal base plate 8.

[0027] Furthermore, the oil inside the heating tube 11 enters the guide tube 9 through the first connecting tube 10, and can heat the metal base plate 8 again through the guide tube 9. The oil can also flow back to the heat dissipation tube 3 through the return tube 4. The oil inside the return tube 4 can be heated by the electric heating wire 5, which can make the oil circulate and be continuously heated.

[0028] When the mold needs to be cooled, the operator can turn off the electric heating wire 5 through the control panel 6 to stop the heating process, and then start the air pump 2 through the control panel 6. The air pump 2 draws the outside cold air into the inside of the diversion pipe 16 through the air guide pipe 1, and blows the cold air evenly to different positions of the heat dissipation pipe 3 through the nozzle 15, so as to dissipate heat from the heat dissipation pipe 3 and make the heat dissipate quickly.

[0029] The cooled oil flows into the heating pipe 11 and the guide pipe 9, which can dissipate heat from the metal base plate 8 and the metal heat-conducting column 12. This allows the heat on the mold to exchange with the oil through the guide pipe 9, which can quickly dissipate the heat on the mold and thus cool it down.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
