[0002] A die-casting machine is a machine used for pressure casting. It includes two types: hot-chamber and cold-chamber. The latter is further divided into vertical and horizontal types. Under pressure, the die-casting machine injects molten metal into a mold to cool and solidify. After the mold is opened, a solid metal casting is obtained. It was initially used for die-casting lead type.

[0003] Patent CN218693719U discloses a cooling device for a die-casting machine with good cooling effect. In use, the operator first connects the inlet pipe to the inlet connection port and the outlet pipe to the outlet connection port, then starts the water pump to pump cooling water into the cooling pipes inside the injection chamber. However, this device still has some problems in practical application:

[0004] 1. Temperature stratification is prone to occur during the circulation of cooling water, resulting in inconsistent cooling effects in different parts of the injection chamber.

[0005] 2. The heat dissipation structure (such as one-way flow obstruction mechanism and heat sink) has low heat dissipation efficiency and cannot quickly dissipate heat to the surrounding environment. Utility Model Content

[0006] The purpose of this invention is to provide a cooling device for a die-casting machine with good cooling effect, which can overcome the shortcomings of the prior art. It achieves efficient cooling through the vaporization and liquefaction process of low-boiling-point coolant, and enhances the heat dissipation effect through structures such as condenser plates, heat dissipation fins and heat dissipation bases. At the same time, it uses the refrigeration system in the cooling cabinet to ensure the low temperature of the coolant.

[0007] To achieve the above objectives, a cooling device for a die-casting machine with good cooling effect is provided, including an injection chamber sleeve, a cooling circulation chamber is provided inside the injection chamber sleeve, a liquid extraction pipe and a liquid delivery pipe are fixedly connected to the side wall of the cooling circulation chamber, and the interior of the cooling circulation chamber is filled with a low boiling point coolant.

[0008] A condenser plate is fixedly connected to the upper inner wall of the cooling circulation chamber. Several heat dissipation fins are fixedly connected to the upper side wall of the condenser plate. Several heat dissipation seats are fixedly connected to the upper side wall of the heat dissipation fins. The injection chamber sleeve is connected to a cooling cabinet through a liquid extraction pipe and a liquid delivery pipe.

[0009] According to the aforementioned cooling device for a die-casting machine with good cooling effect, the outlet end of the extraction pipe is located on the upper side of the cooling circulation chamber, which facilitates the extraction of low-boiling-point coolant with a higher temperature on the upper side, and the inlet end of the delivery pipe is located on the lower side of the cooling circulation chamber, which facilitates the introduction of the cooled low-boiling-point coolant into the bottom of the cooling circulation chamber.

[0010] According to the aforementioned cooling device for a die-casting machine with good cooling effect, a liquid pump is installed on the rear side wall of the cooling cabinet. The output end of the liquid pump is fixedly connected to the liquid delivery pipe, and the input end of the liquid pump is connected to the interior of the cooling cabinet. The liquid pump can extract the cooled low-boiling-point coolant from the cooling cabinet.

[0011] According to the aforementioned cooling device for a die-casting machine with good cooling effect, the cooling cabinet is provided with a cooling chamber inside. The cooling chamber is connected to the interior of the cooling circulation chamber through a liquid extraction pipe and a liquid delivery pipe, so that the low-boiling-point coolant can circulate between the cooling chamber, the liquid extraction pipe, the liquid delivery pipe and the cooling circulation chamber.

[0012] According to the aforementioned cooling device for a die-casting machine with good cooling effect, the condensing plate and multiple heat dissipation fins are made using an integral molding technology, which improves the heat conduction efficiency between the condensing plate and the heat dissipation fins.

[0013] According to the aforementioned cooling device for a die-casting machine with good cooling effect, each of the heat sinks is equipped with several cooling fans to accelerate the gas flow speed at the heat sink fins, thereby improving the heat dissipation effect of the heat sink fins.

[0014] According to the aforementioned cooling device for a die-casting machine with good cooling effect, the cooling cabinet is equipped with a refrigeration system, which consists of a compressor, a condenser, an evaporator, and a throttling device. The compressor is the core component of the cooling cabinet, responsible for compressing the refrigerant and circulating it in the system to achieve refrigeration. The condenser cools the high-temperature and high-pressure gas discharged from the compressor, turning it into a liquid. The refrigerant evaporates in the evaporator, absorbing heat from inside the cooling cabinet, thereby lowering the temperature. The throttling device is an expansion valve used to control the flow rate and pressure of the refrigerant.

[0015] According to the aforementioned cooling device for a die-casting machine with good cooling effect, the low-boiling-point coolant is set as one of ethylene glycol solution, mineral oil or silicone oil. After absorbing heat, the low-boiling-point coolant will rapidly vaporize, move upward, and liquefy upon encountering the condenser plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. Compared with existing technologies, this invention achieves highly efficient cooling through the vaporization and liquefaction process of a low-boiling-point coolant, significantly improving cooling efficiency. The low-boiling-point coolant rapidly vaporizes after absorbing heat, rises to the condenser plate where it liquefies upon contact with the cooler surface, forming a natural circulation. This design can quickly absorb the heat generated in the injection chamber, shortening the cooling time, while simultaneously ensuring the stability and continuity of the cooling effect through a rapid response to high-temperature demands via the refrigeration system.

[0018] 2. Compared with existing technologies, this invention significantly improves heat dissipation through the synergistic effect of the condenser plate, heat dissipation fins, and cooling fan. The condenser plate and heat dissipation fins are integrally molded to ensure high thermal conductivity; the cooling fan accelerates the airflow around the heat dissipation fins, enhancing air convection. This design effectively avoids temperature stratification, ensuring uniform cooling of all parts of the injection chamber, and further improves heat dissipation efficiency through optimized heat dissipation structure.

[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Example 1:

[0028] Reference Figure 1-4This utility model provides a cooling device for a die-casting machine with good cooling effect, which includes an injection chamber sleeve 1. The injection chamber sleeve 1 has a cooling circulation chamber 104 inside. The side wall of the cooling circulation chamber 104 is fixedly connected to a liquid extraction pipe 101 and a liquid delivery pipe 102. The cooling circulation chamber 104 is filled with a low-boiling-point coolant 103. The low-boiling-point coolant 103 is one of ethylene glycol solution, mineral oil or silicone oil. After absorbing heat, the low-boiling-point coolant 103 will quickly vaporize and move upward. After encountering the condenser plate 105, it will liquefy upon cooling.

[0029] The outlet end of the extraction pipe 101 is located on the upper side of the cooling circulation chamber 104, which facilitates the extraction of the low-boiling-point coolant 103 with a higher temperature on the upper side. The inlet end of the delivery pipe 102 is located on the lower side of the cooling circulation chamber 104, which facilitates the introduction of the cooled low-boiling-point coolant 103 into the bottom of the cooling circulation chamber 104.

[0030] A condenser plate 105 is fixedly connected to the upper inner wall of the cooling circulation chamber 104. Several heat dissipation fins 2 are fixedly connected to the upper side wall of the condenser plate 105. Several heat dissipation bases 3 are fixedly connected to the upper side wall of the heat dissipation fins 2. The condenser plate 105 and the multiple heat dissipation fins 2 are made of integral molding technology to improve the heat conduction effect between the condenser plate 105 and the heat dissipation fins 2. Several cooling fans 301 are provided inside each heat dissipation base 3 to accelerate the air flow from the heat dissipation fins 2, thereby improving the heat dissipation effect of the heat dissipation fins 2.

[0031] The injection chamber sleeve 1 is connected to the cooling cabinet 4 through the liquid extraction pipe 101 and the liquid delivery pipe 102. The liquid delivery pump 401 is installed on the rear side wall of the cooling cabinet 4. The output end of the liquid delivery pump 401 is fixedly connected to the liquid delivery pipe 102. The input end of the liquid delivery pump 401 is connected to the interior of the cooling cabinet 4. The liquid delivery pump 401 can extract the cooled low boiling point coolant 103 from the cooling cabinet 4. The interior of the cooling cabinet 4 is provided with a cooling chamber. The cooling chamber is connected to the interior of the cooling circulation chamber 104 through the liquid extraction pipe 101 and the liquid delivery pipe 102, so that the low boiling point coolant 103 can circulate between the cooling chamber, the liquid extraction pipe 101, the liquid delivery pipe 102 and the cooling circulation chamber 104.

[0032] The cooling cabinet 4 is equipped with a refrigeration system 402, which consists of a compressor, a condenser, an evaporator, and a throttling device. The compressor is the core component of the cooling cabinet 4, responsible for compressing the refrigerant and circulating it in the system to achieve refrigeration. The condenser cools the high-temperature and high-pressure gas discharged from the compressor, turning it into a liquid. The refrigerant evaporates in the evaporator, absorbing heat from inside the cooling cabinet 4 to lower the temperature. The throttling device is an expansion valve used to control the flow rate and pressure of the refrigerant.

[0033] Working principle: During the die casting process, the heat generated in the injection chamber is absorbed by the low-boiling-point coolant 103 in the cooling circulation chamber 104. The coolant rapidly vaporizes and moves upward to the condenser plate 105. On the condenser plate 105, the vaporized coolant liquefies upon cooling. The liquefied coolant flows back to the cooling circulation chamber 104 along the condenser plate 105. The liquid extraction pipe 101 extracts the coolant at the top with a higher temperature, and the liquid delivery pipe 102 introduces the cooled coolant into the bottom of the cooling circulation chamber 104 to form a circulation. The refrigeration system 402 in the cooling cabinet 4 further reduces the temperature of the coolant, ensuring the stability and continuity of the cooling effect.

[0034] Unless otherwise specified, the constituent units in this utility model are obtained from conventional commercial channels or manufactured by conventional methods. Their specific structure, working principle, and possible control methods and spatial arrangement methods can adopt conventional choices in the field and should not be regarded as the innovation of this utility model. This is understandable to those skilled in the art, and this utility model patent will not be further elaborated in detail.

[0035] Example 2:

[0036] The difference between this embodiment and Embodiment 1 is that the cooling cabinet 4 does not use a cooling system to cool the coolant; instead, an external condenser tower cools the coolant using cooling water within the tower. This design is suitable for scenarios requiring greater cooling capacity and can further improve cooling efficiency.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
