Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to a cooling device for a vertical rotary injection molding machine. Background Technology

[0002] Vertical rotary injection molding machines are specialized equipment widely used in the plastics processing industry. Unlike traditional horizontal injection molding machines, vertical rotary injection molding machines adopt a vertical structure, meaning the injection unit and mold clamping unit are arranged vertically. This design results in a relatively small footprint, offering significant advantages in space-constrained production environments, especially suitable for small processing workshops or production lines with high space requirements. Its core component is a rotating turntable, typically located in the center of the machine. Multiple molds can be mounted on the turntable; the standard configuration is two stations, but three, four, or more stations can be selected for special requirements, enabling multi-cavity mold production or alternating mold production, greatly improving production efficiency.

[0003] Traditional cooling devices do not utilize the heat of the mold, resulting in a significant waste of energy when cooling and heating the mold. Utility Model Content

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When mold cooling is required, the reversible water pump is driven to draw coolant from the right-side storage tank. The coolant is cooled by the heat dissipation component and then enters the rotating assembly through the right-side main pipe to exchange heat with the mold, thereby reducing the mold temperature and facilitating demolding. The high temperature of the mold heats the coolant, which then flows into the left-side storage tank through the left-side main pipe for later use. When demolding is complete and mold heating is required, the reversible water pump is driven to pump the coolant from the storage tank into the heating assembly. Since the coolant was heated by the mold during previous cooling, the heating assembly can quickly heat the coolant and save energy. The heated coolant then enters the rotating assembly through the left-side main pipe to exchange heat with the mold, thereby heating the mold. At the same time, the coolant cools down and is discharged through the right-side main pipe, passing through the heat dissipation component for further cooling before finally being discharged into the right-side storage tank for later use. This process is repeated, making full use of the mold's heat and saving energy. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4As shown, the cooling device for the vertical rotary injection molding machine includes a cabinet 1, a turntable 2 is provided in the middle of the upper side of the cabinet 1, molds 3 are provided on the front and rear sides of the upper part of the turntable 2, and cooling mechanisms 4 are provided on the left and right sides of the molds 3.

[0021] The cooling mechanism 4 includes a rotating assembly 401, two main pipes 402 (left and right), two liquid storage tanks 403 (left and right), a heat dissipation assembly 404, and a heating assembly 405. The liquid storage tanks 403 are installed on the lower left and right sides of the cabinet 1. The left liquid storage tank 403 is connected to the left main pipe 402 via the heating assembly 405, and the right liquid storage tank 403 is connected to the right main pipe 402 via the heat dissipation assembly 404. The heating assembly 405 is installed on the left side of the cabinet 1, and the heat dissipation assembly 404 is installed on the right side of the cabinet 1. The main pipes 402 are installed on the left and right sides of the rotating assembly 401. The rotating assembly 401 is installed on the upper part of the turntable 2 and is connected to the mold 3. A reversible water pump is installed inside the left liquid storage tank 403. The output end of the reversible water pump is connected to the liquid storage tank 403. When cooling of the mold 3 is required, the reversible water pump is driven to draw coolant from the right liquid storage tank 403, allowing the coolant to be cooled by the heat dissipation assembly 404, and then discharged through the right... The side main pipe 402 enters the rotating assembly 401 and exchanges heat with the mold 3, thereby reducing the temperature of the mold 3 and facilitating demolding. The high temperature of the mold 3 heats the coolant, which then flows into the left-side storage tank 403 through the left-side main pipe 402 for later use. When demolding is complete and the mold 3 needs to be heated, a reversible water pump is driven to pump the coolant from the storage tank 403 into the heating assembly 405 for heating. Since the coolant was heated by the mold 3 during the previous cooling process, the heating assembly 405 can quickly heat the coolant and save energy. The heated coolant then enters the rotating assembly 401 through the left-side main pipe 402 to exchange heat with the mold 3, thereby heating the mold 3. At the same time, the coolant cools down and is discharged through the right-side main pipe 402. After being cooled by the heat dissipation assembly 404, it is finally discharged into the right-side storage tank 403 for later use. This process is repeated, making full use of the heat of the mold 3 and saving energy.

[0022] The heat dissipation assembly 404 includes a flow box 4041, heat-conducting fins 4042, a fan 4043, an exhaust port 4044, an air inlet 4045, and a protective shell 4046. The flow box 4041 is installed on the right side of the cabinet 1. One side of the heat-conducting fins 4042 penetrates the right side wall of the flow box 4041 and is fixedly connected to the middle of the flow box 4041. The fan 4043 is installed on the right side of the heat-conducting fins 4042. The air inlet 4045 is installed on the right side of the flow box 4041, and the protective shell 4046 is fitted around the outer periphery of the heat-conducting fins 4042 and the fan 4043. The outlet 4045 is located on the right side of the protective shell 4046, and the exhaust port 4044 is located on the upper and lower sides of the protective shell 4046. When the coolant comes into contact with the heat-conducting fin 4042, it will transfer heat to the heat-conducting fin 4042, and dissipate heat through the heat-conducting fin 4042. Then, the fan 4043 accelerates the heat dissipation speed of the coolant. The heat-conducting fin 4042 divides the inside of the flow box 4041 into many small channels, thereby increasing the contact area between the heat-conducting fin 4042 and the coolant, and thus accelerating the heat dissipation speed of the coolant through the heat-conducting fin 4042.

[0023] The protective shell 4046 has a filter screen inside, which is aligned with the exhaust port 4044 and the air inlet 4045 to prevent dust from adhering to the heat-conducting fins 4042 and ensure heat dissipation.

[0024] The heating assembly 405 includes a second flow box 4051, a second heat-conducting fin 4052, and a heat insulation cover 4053. The second flow box 4051 is installed on the left side of the cabinet 1. One side of the second heat-conducting fin 4052 passes through the side wall of the second flow box 4051 and is fixedly connected to the middle of the second flow box 4051. A heating wire is installed on the other side of the second heat-conducting fin 4052. A heat insulation cover 4053 is provided on the left side of the second flow box 4051. The heat insulation cover 4053 is sleeved on the outer periphery of the second heat-conducting fin 4052. The second heat-conducting fin 4052 is heated by the heating wire, and then the coolant is heated by the second heat-conducting fin 4052.

[0025] Both the second flow box 4051 and the first flow box 4041 have a flow divider 4047 on the upper side inside, which distributes the coolant to each channel and increases the heat dissipation speed of the coolant.

[0026] The rotating assembly 401 includes an annular water tank 4011, an annular cover 4012, a partition 4013, a secondary pipe 4014, and a cooling pipe. The bottom of the annular water tank 4011 is fixedly connected to the upper part of the turntable 2. The lower part of the annular cover 4012 is located on the upper part of the annular water tank 4011. The upper end of the partition 4013 is fixedly connected to the lower parts of the front and rear sides of the annular cover 4012. The outer periphery of the partition 4013 is located inside the front and rear sides of the annular water tank 4011. One end of the secondary pipe 4014 is fixedly connected to the beginning and end of the cooling pipe. The other end of the secondary pipe 4014 is connected to the side wall of the annular water tank 4011. The cooling pipe is located inside the mold 3. By connecting the annular cover 4012 to the main pipe 402, the turntable 2 can drive the annular water tank 4011 to rotate without affecting the main pipe 402. The partition 4013 divides the interior of the annular water tank 4011 into two chambers, allowing water to enter one chamber and clean water to exit the other.

[0027] Working principle:

[0028] When cooling of mold 3 is required, the reversible water pump is driven to draw coolant from the right-side storage tank 403. The coolant is then cooled by the heat dissipation assembly 404 and enters the rotating assembly 401 through the right-side main pipe 402 to exchange heat with mold 3, thereby reducing the temperature of mold 3 and facilitating demolding. The high temperature of mold 3 heats the coolant, which then flows through the left-side main pipe 402 into the left-side storage tank 403 for later use. When demolding is complete and mold 3 needs to be heated, the reversible water pump is driven to cool the coolant inside the storage tank 403. The coolant is pumped into the heating assembly 405 for heating. Since the coolant was heated by the mold 3 during the previous cooling process, the heating assembly 405 can quickly heat the coolant and save energy. The heated coolant enters the rotating assembly 401 through the main pipe 402 on the left to exchange heat with the mold 3, thereby heating the mold 3. At the same time, the coolant cools down and is discharged through the main pipe 402 on the right. It is then cooled by the heat dissipation assembly 404 and finally discharged into the storage tank 403 on the right for later use. This process is repeated to make full use of the heat of the mold 3 and save energy.
