Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to a rapid cooling device for a plastic injection molding machine. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are classified as vertical, horizontal, and all-electric. Injection molding machines heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity.

[0003] Chinese patent document CN221365702U discloses a rapid cooling device for a plastic injection molding machine. Water is added to a circulating water tank through a water inlet pipe, and a water pump draws cold water from the circulating water tank through a water outlet pipe and delivers it to a distribution tank. The water is then sent to the molding mold cooling chamber and the injection mold cooling chamber through water inlet pipes. The water flowing out of the molding mold cooling chamber and the injection mold cooling chamber will return to the circulating water tank through a return pipe for cooling, which can effectively save water resources.

[0004] However, in the above scheme, the cold water after heat exchange is directly transported back into the circulating water tank. Since the cold water after heat exchange has a temperature, it will cause the temperature of the cold water in the circulating water tank to rise, resulting in a reduction in the subsequent cooling effect.

[0030] Example 1

[0031] like Figure 1-5 As shown, the present invention proposes a rapid cooling device for a plastic injection molding machine, comprising a mounting block 1, a water storage tank 11, a connector 15, and a conveying assembly.

[0032] There are two mounting blocks 1. The end faces of the two mounting blocks 1 are respectively provided with a first mold 2 and a second mold 3, and the first mold 2 and the second mold 3 are arranged opposite to each other. The two mounting blocks 1 are respectively enclosed with the first mold 2 and the second mold 3 to form a cooling cavity.

[0033] The connector 15 is disposed on the end face of the second mold 3 and inserted into the end face of the first mold 2, and the connector 15 is interconnected with the two cooling chambers for connecting the two cooling chambers during use.

[0034] The conveying assembly is installed on one side of the first mold 2 and extends to the inner top of the water storage tank 11. The middle and end of the conveying assembly are respectively provided with heat dissipation pipes 6 and atomizing nozzles 10 for dissipating heat from cold water during use. The heat dissipation pipes 6 are spiral or S-shaped. The heat dissipation pipes 6 are made of high-efficiency heat conduction materials, such as copper and aluminum, and are used to quickly exchange heat with the water after heat exchange during use to cool it down. In addition, a cold air fan can be installed on the side of the heat dissipation pipes 6 during use to improve the heat exchange speed of the heat dissipation pipes 6.

[0035] In this embodiment, the first mold 2 and the second mold 3 are respectively installed on the mounting block 1, and the two mounting blocks 1 are connected to the first mold 2 and the second mold 3 respectively to form a cooling cavity. Cold water is pumped into the inner side of the cooling cavity. At the same time, the two cooling cavities are connected by the connector 15 when the first mold 2 and the second mold 3 are connected, so that cold water is delivered to the two cooling cavities at the same time, so that the cold water exchanges heat with the first mold 2 and the second mold 3 at the same time, and the first mold 2 and the second mold 3 perform cooling work, improving the cooling uniformity and cooling effect. The cold water after heat exchange is delivered to the water storage tank 11 through the conveying assembly. During the conveying process, the heat dissipation pipe 6 and the atomizing nozzle 10 respectively dissipate heat and cool down the water, so as to prevent the water in the water storage tank 11 from rising in temperature.

[0036] Example 2

[0037] like Figure 1-2 As shown, the present invention proposes a rapid cooling device for a plastic injection molding machine. Compared with the first embodiment, the difference in this embodiment is that the conveying component includes a hose 5, a connecting pipe 8, and a distribution pipe 9.

[0038] The flexible hose 5 is installed on one side of the first mold 2, and the other end is connected to the heat dissipation pipe 6. It is used to follow the first mold 2 when the first mold 2 and the second mold 3 are separated during use.

[0039] The connecting pipe 8 is located at one end of the heat dissipation pipe 6 and extends to the inner top of the water storage tank 11, and is connected to the heat dissipation pipe 6.

[0040] The distribution pipe 9 is installed at the end of the connecting pipe 8 and is located inside the water storage tank 11 and communicates with the atomizing nozzle 10. The shape of the distribution pipe 9 is one of circular or S-shaped, etc., and is used to make the water sprayed by the multiple atomizing nozzles 10 cover the inner top of the water storage tank 11.

[0041] In an optional embodiment, a heat sink 7 is provided on the outside of the heat pipe 6. There are multiple heat sinks 7, which are arranged at equal distances on the outside of the heat pipe 6 to increase the contact area between the heat pipe 6 and the air during use.

[0042] In this embodiment, the hose 5, due to its inherent characteristics, moves its end along with the first mold 2, and the hose 5 transports the hot water discharged from the cooling chamber to the heat dissipation pipe 6. Multiple heat dissipation fins 7 are arranged on the outside of the heat dissipation pipe 6, and their shapes match the shape of the heat dissipation pipe 6, increasing the contact area between the heat dissipation pipe 6 and the air, thereby improving the heat dissipation area and efficiency. The cooled water effectively cools down during its transport within the heat dissipation pipe 6 after heat exchange. Through the cooperation of the connecting pipe 8 and the distribution pipe 9, the cooled water is transported to multiple atomizing nozzles 10. Simultaneously, the atomizing nozzles 10 spray the cooled water into the inner side of the water storage tank 11 in a mist form, further cooling the cooled water after heat exchange.

[0043] Example 3

[0044] like Figure 3-5 As shown, the present invention proposes a rapid cooling device for a plastic injection molding machine. Compared with the first embodiment, the difference in this embodiment is that the cooling cavity includes a slot 16, a connecting slot 17, a flow channel 19, a first connecting pipe 4, and a second connecting pipe 12.

[0045] The slot 16 is located in the middle of the end face of the mounting block 1;

[0046] There are two connecting slots 17, which are respectively located in the middle of the other end face of the second mold 3 and the first mold 2 and communicate with the slot 16.

[0047] The number of flow channels 19 is multiple, and the multiple flow channels 19 are respectively arranged on both sides of the first mold 2 and the second mold 3 and connected to them. The flow channel 19 on the second mold 3 is connected to the connector 15.

[0048] The first connecting pipe 4 and the second connecting pipe 12 are respectively installed on both sides of the first mold 2 and communicate with the cooling cavity. The first connecting pipe 4 is connected to the pump body and is used to deliver cold water to the inside of the two cooling cavities through the first connecting pipe 4 and discharge it through the second connecting pipe 12 during use. The connection between the hose 5 and the second connecting pipe 12 and the connection between the first connecting pipe 4 and the water pump are all movable connections. During use, the hose 5 can be separated from the second connecting pipe 12 and connected to the first connecting pipe 4, while the second connecting pipe 12 is connected to the water pump, so that the inlet and outlet water positions can be changed.

[0049] In an optional embodiment, an installation groove 18 is provided on the end face of the first mold 2 and at the end of the flow channel 19. The installation groove 18 communicates with the flow channel 19. When the connector 15 is installed in conjunction with the first mold 2, the connector 15 is accommodated in the installation groove 18 for sealing connection between the connector 15 and the first mold 2 during use.

[0050] In this embodiment, by providing connecting grooves 17 on the second mold 3 and the first mold 2, and by providing a slot 16 on the mounting block 1 that mates with the connecting grooves 17, when the mounting block 1 is connected to the first mold 2 and the second mold 3, the slot 16 connects with the connecting grooves 17 to form a cavity. At the same time, by providing flow channels 19 on both sides of the first mold 2 and the second mold 3, and by communicating the flow channels 19 with the cavity, the flow channels 19 can deliver cold water to and discharge cold water into the cavity, thereby cooling the first mold 2 and the second mold 3. Meanwhile, by connecting the two cavities together with the joint 15 and the mounting groove 18, the addition and discharge of cold water into the cavity is more convenient and faster.

[0051] Example 4

[0052] like Figure 3-4 As shown, the present invention proposes a rapid cooling device for a plastic injection molding machine. The difference between this embodiment and embodiment three is that multiple guide plates 14 are arranged at equal intervals on the inner side of the connecting groove 17, and the multiple guide plates 14 are arranged alternately in the upper and lower parts of the inner side of the connecting groove 17.

[0053] In an optional embodiment, a boss 13 is provided on the other end face of the second mold 3 and the first mold 2 at the edge of the connecting groove 17. When the first mold 2 and the second mold 3 are respectively installed in conjunction with the mounting block 1, the boss 13 is accommodated in the slot 16.

[0054] In an optional embodiment, the first mold 2 is provided with an injection tube 20 that penetrates the mounting block 1 in the middle. The outer diameter of the injection tube 20 is smaller than the distance between the two guide plates 14. This is used to add injection liquid between the first mold 2 and the second mold 3 during use, and to prevent the injection tube 20 from blocking the cold water guided by the guide plate 14 inside the connecting groove 17.

[0055] In this embodiment, by setting multiple guide plates 14 inside the connecting groove 17 and guiding the water flow inside the connecting groove 17, the guide plates 14 conduct heat to the first mold 2 and the second mold 3, so that the cold water exchanges heat with the first mold 2 and the second mold 3 while exchanging heat with the guide plates 14, thereby improving the cooling efficiency.

[0056] In this invention, a cooling cavity is formed by mounting the first mold 2 and the second mold 3 on mounting blocks 1, with the slots 16 on the two mounting blocks 1 connected to the connecting slots 17 on the first mold 2 and the second mold 3, respectively. A first connecting pipe 4 connects to a pump body, allowing cold water to be delivered into the cooling cavity via a flow channel 19. Simultaneously, the connector 15, in conjunction with the mounting slot 18, connects the two cooling cavities, enabling cold water to be delivered to both cavities simultaneously, facilitating heat exchange between the cold water and the first mold 2 and the second mold 3. Furthermore, multiple guide plates 14 are arranged inside the connecting slots 17, guiding the water flow and conducting heat between the guide plates 14 and the first mold 2 and the second mold 3. This increases the heat exchange area of ​​the first mold 2 and the second mold 3, improving the cooling effect. The cooled water, after heat exchange, is connected to the second connecting pipe 12 via another distribution pipe 9. The cooled water is then transported to the hose 5 via the heat dissipation pipe 6 and then to the connecting pipe 8. During its movement within the heat dissipation pipe 6, the pipe exchanges heat with the cooled water, cooling it down. Multiple heat dissipation fins 7, with shapes matching the pipe 6, are installed on the outside of the pipe, increasing the contact area between the pipe 6 and the air, thus improving its heat dissipation area and efficiency. This effectively lowers the temperature of the cooled water as it is transported within the pipe 6. Simultaneously, the connecting pipe 8, through the distribution pipe 9, delivers water to multiple atomizing nozzles 10, which spray the cooled water into the inner side of the water storage tank 11 in a mist-like manner, further cooling the water. This creates a mist-like cooling effect within the water storage tank 11, preventing the water temperature from rising.

[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
