Description

Technical Field

[0001] This utility model relates to the field of mold temperature controller technology, specifically a multi-functional gas-fired mold temperature controller. Background Technology

[0002] A gas-fired mold temperature controller is a device that uses gas as a heat source to heat and control the temperature of molds or fluids. Its working principle is based on the heat energy generated by the combustion of gas, which is then used in a specific system to control the temperature of the mold or fluid. According to the characteristics of plastic injection molding processes, gas-fired mold temperature controllers can control the temperature of the mold using the heat energy generated by the combustion of gas, thereby achieving temperature control during the injection molding process. They can provide precise temperature control under high-temperature conditions, meeting the molding requirements of complex plastic parts, and are widely used in industries such as chemical, grease, plastics, textiles, fibers, papermaking and printing, wood, metal, and coating.

This invention has the following advantages and effects: after the heated heat transfer oil is recovered through the oil outlet pipe, the hot oil will circulate back through the return oil pipe, passing through the interior of the cooling tank where it is cooled by the circulating cooling water. After the initially cooled heat transfer oil is pumped into the return pipe, the return oil cylinder protects its exterior, reducing the rate of temperature change and ensuring safer recovery. Furthermore, when needed, the oil tank and the oil inlet pipe can work together to replenish the heating cylinder with heat transfer oil, preventing insufficient oil from affecting the efficiency of constant temperature operation.

[0004] However, the aforementioned published document on a gas-fired intelligent mold temperature controller mainly considers preventing insufficient oil volume from affecting the efficiency of constant temperature operation, and also addresses the problem of not being able to filter the gas entering the mold temperature controller.

[0005] Therefore, it is necessary to develop a filtration mechanism to filter the gas entering the mold temperature controller, so that the fuel can be fully burned to provide sufficient heat to the external mold. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a filtration mechanism to filter the gas entering the mold temperature controller, ensuring complete combustion of the fuel for adequate heating of the external mold. Existing gas contains numerous impurities such as large particles, dust, and moisture, leading to incomplete combustion in the combustion chamber and insufficient heating of the external mold.

The oil inlet pipe of the return oil pump 9 is located inside the cooling box 10. Multiple sets of cooling pipes are fixedly installed on the inner wall of the cooling box 10. First, the flange pipe 4 is used to connect with the external gas supply equipment, and then the gas enters the combustion chamber 6. The oil supply pump 3 is used to supply oil (heat transfer medium, such as heat transfer oil) to the hot oil chamber 7. The combustion chamber 6 heats the medium in the hot oil chamber 7. The external equipment mold is heated through the oil supply pipe 8. After completion, the medium needs to be recovered. The medium is recovered through the return oil pump 9 and cooled through the cooling pipe in the cooling box 10, and then returned to the hot oil chamber 7, thus completing the work.

[0027] Please see Figure 2 and Figure 3A filter mechanism is provided at the top of flange pipe 4. The filter mechanism is used to filter the fuel entering the mold temperature controller to ensure complete combustion of the fuel and provide sufficient heat to the external mold.

A filter cylinder 16 is fixedly installed at the bottom of the splicing plate 14. The filter cylinder 16 is located between the splicing plate 14 and the connecting flange 4. Between flanges 13, a stop block 17 is installed on the inner wall of filter cartridge 16. Below the stop block 17 is a preliminary filter layer 18, and below the preliminary filter layer 18 is a finer filter layer 19. The inner wall of filter cartridge 16 has a threaded groove 20, and a threaded block 21 is threadedly installed on the inner wall of the threaded groove 20. The threaded block 21 is cylindrical. An assembly plate 22 is fixedly installed on the outer wall of filter cartridge 16. The assembly plate 22 is installed to the connecting flange 13 by bolts. The preliminary filter layer 18 is made of stainless steel filter element material, and the finer filter layer 19 is made of glass fiber. The existing gas used for filter material contains a large number of impurities, such as large particles, dust, and moisture. These impurities lead to incomplete combustion of the gas in the combustion chamber 6, resulting in insufficient heating of the external mold. Therefore, improvements are needed. First, the filter cartridge 16 is connected to the flange pipe 4 using the connecting flange 13. Then, the filter cartridge 16 is fixedly connected to the connecting flange 13 using the assembly plate 22 and bolts. The splicing plate 14 is used to connect to the external pipeline, and the splicing plate 14 is always designed to be paired with the external pipeline.

They are fixed to the threaded groove 20 by the threaded locking block 21. The stop block 17 and the threaded locking block 21 limit the sub-filter layer 19 and the preliminary filter layer 18. Thus, the preliminary filter layer 18 filters large impurities, and the sub-filter layer 19 filters small particles, dust, moisture and other impurities, improving the purity of the gas. At the same time, the sub-filter layer 19 and the preliminary filter layer 18 can be disassembled and replaced, which facilitates better filtration of the gas in the future.

[0028] Please see Figure 2 and Figure 4The outer wall of the mold temperature controller housing 1 is equipped with a heat preservation mechanism. This mechanism is used to keep the medium flowing inside the oil supply pipe 8 warm, preventing temperature changes during transportation that could prevent sufficient heating of the external mold. The heat preservation mechanism includes an upper cover 23, which is located on the outer wall of the mold temperature controller housing 1. A lower cover 24 is located at the bottom of the upper cover 23. A first mounting plate 25 is installed on the outer wall of the upper cover 23, and a second mounting plate 26 is installed on the outer wall of the lower cover 24. The first mounting plate 25 is assembled with the lower cover 24 by bolts. Rock wool insulation layers 27 are installed on the inner walls of both the upper cover 23 and the lower cover 24. A glass insulation layer is installed on the outer wall of the rock wool insulation layer 27. The existing oil supply pipe 8 often experiences temperature fluctuations due to external temperatures during medium transport, resulting in insufficient heating of the external mold. Therefore, improvements are needed. First, the upper cover 23 is magnetically attached to the outside of the mold temperature controller housing 1. Then, the upper cover 23 and lower cover 24 are connected by bolts using the first mounting plate 25 and the second mounting plate 26. Next, the oil supply pipe 8 is insulated with a rock wool insulation layer 27, and the glass wool insulation layer 28 provides further insulation while also providing sound insulation, reducing external influences and preventing insufficient heating due to large temperature fluctuations in the medium.

[0029] Working principle: First, flange pipe 4 is used to connect to the external gas supply equipment, then the gas enters the combustion chamber 6. Oil pump 3 supplies oil (a heat transfer medium, such as heat transfer oil) to the hot oil chamber 7. Combustion chamber 6 heats the medium in hot oil chamber 7, and the oil supply pipe 8 heats the external equipment mold. After completion, the medium needs to be recovered. The medium is recovered by return oil pump 9 and cooled by cooling pipes in cooling box 10 before returning to hot oil chamber 7, thus completing the work. Existing gas may contain a large number of impurities, such as... Large particles, dust, moisture, and other impurities can cause incomplete combustion of the gas in the combustion chamber 6, resulting in insufficient heating of the external mold. Therefore, improvements are needed. First, the connecting flange 13 is connected to the flange pipe 4. Then, the filter cylinder 16 is fixedly connected to the connecting flange 13 using the assembly plate 22 and bolts. The splicing plate 14 is used to connect to the external pipeline. The splicing plate 14 and the external pipeline are always designed to be matched. The preliminary filter layer 18 is attached to the baffle block 17, and the subdivided filter layer 1... 9 is attached to the preliminary filter layer 18 and fixed to the threaded groove 20 by the threaded clamp 21. The stop block 17 and the threaded clamp 21 limit the movement of the subdivision filter layer 19 and the preliminary filter layer 18. The preliminary filter layer 18 filters large impurities, while the subdivision filter layer 19 filters small particles, dust, moisture, and other impurities, improving the purity of the fuel gas. At the same time, the subdivision filter layer 19 and the preliminary filter layer 18 can be disassembled and replaced, which facilitates better subsequent filtration of the fuel gas. The existing oil supply pipe 8 is often affected by the external temperature when transporting the medium. The medium temperature in the oil supply pipe 8 is too high, which prevents sufficient heating of the external mold. Therefore, this needs to be improved. First, the upper half cover 23 is magnetically attached to the outside of the mold temperature controller housing 1. Then, the upper half cover 23 and the lower half cover 24 are connected by bolts through the first mounting plate 25 and the second mounting plate 26. Then, the oil supply pipe 8 is insulated with rock wool insulation layer 27, and glass wool insulation layer 28 is used for further insulation and also has a certain sound insulation effect, reducing the impact on the outside world, thereby avoiding the inability to provide sufficient heating due to large changes in medium temperature.
