Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to an injection molding machine motor cooling system. Background Technology

[0002] During operation, the motor of an injection molding machine generates a significant amount of heat, requiring cooling. Currently, water cooling is the most common method used. However, when the water level is unstable, this can lead to insufficient cooling and affect the cooling effect.

[0003] In addition, conventional cooling systems are usually separate and independent systems, meaning that a single cooling system can only cool one motor. However, injection molding machines typically contain multiple motors, such as the main motor and the melting motor. For large-tonnage injection molding machines, there are usually multiple main power motors. Therefore, existing cooling systems need to be equipped with multiple cooling systems, resulting in high equipment costs and occupying factory space. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a motor cooling system for injection molding machines, which can cool multiple motors through one cooling system, avoiding the need to set up multiple cooling systems for one injection molding machine, while ensuring the cooling effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A cooling system for an injection molding machine motor includes a liquid storage tank, a cooler, and a switching block. The liquid storage tank is used to hold coolant, and the cooler is disposed inside the liquid storage tank. The outer wall of the bottom of the liquid storage tank is provided with a liquid replenishment port. The switching block is provided with multiple interconnected liquid inlets and multiple interconnected liquid outlets. The liquid replenishment port is connected to the multiple liquid outlets, and the cooler is connected to any first liquid inlet and any one of the liquid outlets.

[0007] Preferably, the switching block is provided with a liquid inlet chamber, and the plurality of liquid inlets are all connected to the liquid inlet chamber;

[0008] The switching block is provided with a liquid outlet chamber, and the multiple liquid outlets and the liquid replenishment port are all connected to the liquid outlet chamber.

[0009] Preferably, the liquid outlet chamber and the liquid replenishment port are connected by a liquid replenishment pipe, and the liquid replenishment pipe is equipped with a pump and a first valve, with the first valve located between the liquid storage tank and the pump.

[0010] Preferably, the inlet is provided with an inlet pipe, and the inlet pipe is provided with a second valve.

[0011] Preferably, the outlet is provided with an outlet pipe, and the outlet pipe is provided with a third valve.

[0012] Preferably, the side wall of the liquid storage tank is provided with a level gauge, and the level gauge is located above the cooler.

[0013] Preferably, the top of the liquid storage tank is provided with an air inlet, and the air inlet is provided with a filter.

[0014] Preferably, the bottom of the liquid storage tank is provided with support legs.

[0015] This utility model discloses a motor cooling system for an injection molding machine. Compared with the prior art, its advantages lie in the following: By setting multiple interconnected liquid inlets and outlets on the switching block, and connecting the replenishment port to the multiple outlets, and simultaneously connecting the cooler to any first liquid inlet and any outlet, all the liquid inlets and outlets are connected to the cooler. In use, the cooling oil inlets of multiple motors of the injection molding machine can be connected one-to-one with the multiple outlets, and the cooling oil outlets of multiple motors can be connected one-to-one with the multiple liquid inlets. This achieves cooling for multiple motors through a single cooling system, avoiding the need for multiple cooling systems for a single injection molding machine. Furthermore, the cooler itself has good cooling performance, and since it is also placed in a storage tank, the coolant in the tank can exchange heat with the cooler, achieving heat dissipation for the motors connected to the cooler, thus further ensuring the cooling effect of the motors.

[0016] In addition, this application connects the replenishment port to multiple outlet ports, thereby replenishing the coolant in the motor, preventing the motor from running out of coolant, and further ensuring the cooling effect. Attached Figure Description

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0021] It should be noted that in this application, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0023] like Figure 1 , 2 As shown, a preferred embodiment of the present invention provides a cooling system for an injection molding machine motor, comprising a liquid storage tank 1, a cooler 2, and a switching block 3. The liquid storage tank 1 is used to hold coolant, and the cooler 2 is disposed within the liquid storage tank 1 and is completely submerged in the coolant. The outer wall at the bottom of the liquid storage tank 1 has a replenishment port. The switching block 3 has multiple interconnected inlets and outlets, with the replenishment port connected to the outlets. The cooler 2 is connected to any first inlet and any outlet.

[0024] The cooler 2 is preferably a built-in cooler. The heat generated by the motor is transferred to the motor coolant, which circulates with the cooler 2 to achieve cooling. The cooler 2 removes the heat generated by the motor through the circulation of cooling water. It has an inlet and an outlet at one end. Cooling water is pumped into the inlet of the cooler 2 and then flows through the cooling pipes inside the cooler 2, absorbing heat from the motor coolant. Subsequently, the heated cooling water flows out from the outlet, passes through an external cooling system (such as a cooling tower or radiator) for cooling, and then returns to the cooler 2 for circulation.

[0025] Based on the aforementioned technical features, the injection molding machine motor cooling system has multiple interconnected liquid inlets and outlets on the switching block 3. The replenishment port is connected to the multiple outlets. Simultaneously, the cooler 2 is connected to any first liquid inlet and any outlet, thus ensuring that all the liquid inlets and outlets are connected to the cooler 2. In use, the cooling oil inlets of multiple motors of the injection molding machine can be connected one-to-one with the multiple outlets, and the cooling oil outlets of multiple motors can be connected one-to-one with the multiple liquid inlets. This achieves cooling for multiple motors through a single cooling system, avoiding the need for multiple cooling systems on a single injection molding machine. Furthermore, the cooler 2 itself has good cooling performance, and since it is also placed in the liquid storage tank 1, the coolant in the tank 1 can exchange heat with the cooler 2, further dissipating heat from the motors connected to the cooler 2 and ensuring optimal motor cooling.

[0026] In addition, this application connects the replenishment port to multiple outlet ports, thereby replenishing the coolant in the motor, preventing the motor from running out of coolant, and further ensuring the cooling effect.

[0027] In this embodiment, the switching block 3 is provided with a liquid inlet chamber, and multiple liquid inlets are connected to the liquid inlet chamber. The switching block 3 is provided with a liquid outlet chamber, and multiple liquid outlets and a replenishment port are connected to the liquid outlet chamber. Preferably, the multiple liquid inlets are arranged in a row, and the multiple liquid outlets are also arranged in a row; alternatively, the multiple liquid inlets and multiple liquid outlets can be staggered, as long as the liquid inlet chamber and the liquid outlet chamber are independent of each other and do not interfere with each other, such as the liquid inlet chamber and the liquid outlet chamber being arranged one above the other.

[0028] Alternatively, the cooler may not be connected to the liquid inlet and the liquid outlet, but rather to the liquid inlet chamber and the liquid outlet chamber.

[0029] In this embodiment, the liquid outlet chamber and the liquid replenishment port are connected by a liquid replenishment pipe 4. Specifically, one end of the liquid outlet chamber can extend to one side surface of the switching block 3, forming a connection hole on one side of the switching block 3, and the liquid replenishment pipe 4 connects to the connection hole. The liquid replenishment pipe 4 is equipped with a pump 5 and a first valve 6, and the first valve 6 is located between the liquid storage tank 1 and the pump 5, used to control the on / off connection between the liquid storage tank 1 and the pump 5. When liquid replenishment is needed, it is delivered by the action of the pump 5. The pump 5 is preferably a horizontal centrifugal pump, which is convenient to install and has good delivery effect.

[0030] In this embodiment, all motors can be cooled simultaneously, or one or several motors can be selected for cooling as needed. For ease of control, an inlet pipe 7 is provided on the liquid inlet, and a second valve 8 is provided on the liquid inlet; an outlet pipe 9 is provided on the liquid outlet, and a third valve 10 is provided on the liquid outlet. The liquid inlet and outlet correspond one-to-one, forming a group that is connected to one motor. When a motor needs to be cooled, simply open the corresponding second valve 8 and the third valve 10. The motor's coolant enters the inlet chamber from its cooling oil outlet through the second valve 8, then flows into the cooler 2 for cooling, and then flows into the motor's coolant inlet through the third valve 10, completing the entire cooling cycle for the motor.

[0031] Similarly, when cooling a few motors is required, only the corresponding second valve 8 and the third valve 10 need to be opened; when cooling all motors is required, all the second valves 8 and the third valve 10 need to be opened.

[0032] In this embodiment, a level gauge 11 is provided on the side wall of the liquid storage tank 1, and the level gauge 11 is located above the cooler 2, so that the amount of coolant in the liquid storage tank 1 can be monitored in real time.

[0033] Meanwhile, to facilitate the smooth delivery of coolant in the reservoir 1 during replenishment, an air inlet is provided on the top of the reservoir 1 to ensure pressure balance within the reservoir 1 and facilitate coolant delivery. However, to prevent dust or debris from entering the reservoir 1 through the air inlet and contaminating the coolant, an air filter 12 is provided on the air inlet to filter the air entering the reservoir 1.

[0034] In addition, the bottom of the liquid storage tank 1 is provided with support legs 13 to prevent the liquid storage tank 1 from directly contacting the ground and causing corrosion, thereby extending the service life of the liquid storage tank 1.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
