Description

Technical Field

[0001] The present invention mainly relates to the technical field of air conditioner production, and in particular to a cooling and shaping device and a cooling method for producing a fresh air air conditioner shell. Background Art

[0002] Fresh air air conditioner refers to an air conditioner with fresh air mode. In fresh air mode, outdoor air can enter the room.

[0003] The shell of fresh air air conditioner is generally made of plastic and manufactured by injection molding. Air conditioner shell injection cooling is a kind of equipment used in the production process of air conditioner shell, especially in the injection molding process. Its main function is to quickly and evenly cool and shape the air conditioner shell in the mold after the injection molding is completed, so as to ensure the dimensional accuracy, surface smoothness and physical properties of the shell.

[0004] The air cooling method requires a long cooling time. Currently, water cooling is mostly used for cooling. However, when circulating water is used for cooling for a long time, the water begins to heat up with heat exchange, which affects the water cooling effect. Summary of the invention

[0005] The present invention mainly provides a cooling and shaping device and a cooling method for producing a fresh air air conditioner shell to solve the technical problems raised in the above-mentioned background technology.

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] A cooling and shaping device for producing a fresh air air conditioner shell comprises an injection mold, wherein a water cooling flow groove is arranged inside the bottom area of ​​the injection cavity of the injection mold, a water inlet is arranged on one side of the water cooling flow groove, and a plurality of drain ports are arranged at the bottom of the other side of the water cooling flow groove;

[0008] A water cooling mechanism is installed at the bottom of the injection mold, and the water cooling mechanism includes a water cooling box located at the bottom of the injection mold, a water pump installed on one side of the water cooling box, a water pipe with two ends respectively connected to the water pump and the water inlet, and a plurality of communication ports arranged on one side of the water cooling box close to the drain port;

[0009] A plurality of heat dissipation pipes are connected between the plurality of communication ports and the plurality of drainage ports, and a plurality of heat dissipation fans are arranged at the bottom of the injection mold on one side of the heat dissipation pipes.

[0010] Optionally, in the present invention, the water-cooling flow groove is a continuous S-shaped structure.

[0011] Optionally, in the present invention, the wind direction of the heat dissipation fan is toward the heat dissipation pipe.

[0012] Optionally, in the present invention, spiral heat dissipation fins are provided on the heat dissipation pipe.

[0013] Optionally, in the present invention, flanges are provided at both ends of the heat dissipation pipe, flanges are provided on the multiple drain ports and the multiple connecting ports, and the heat dissipation pipe is connected to the drain ports and the connecting ports by two flanges and bolts and nuts.

[0014] Optionally, in the present invention, a water injection pipe is provided on the top of one side of the water cooling box, and a drainage pipe is provided on the water cooling box at the bottom of the water injection pipe.

[0015] Optionally, in the present invention, sealing covers are installed at the openings of the water injection pipe and the drainage pipe by means of internal and external threads, and the water injection pipe is an L-shaped structure.

[0016] Optionally, in the present invention, a viewing mirror is provided on the side of the water cooling box, and the viewing mirror is a transparent acrylic plate.

[0017] Optionally, in the present invention, a water temperature detector penetrating into the interior of the water cooling box is installed on one side of the water cooling box.

[0018] The cooling method used in any of the above-mentioned cooling and shaping devices for producing the fresh air air conditioner shell comprises the following steps:

[0019] Step 1: After the fresh air air conditioner shell is injected into the injection cavity of the injection mold, the water pump is started to allow the coolant inside the water cooling box to enter the water cooling flow groove, and the injection mold is cooled to quickly cool the shell inside;

[0020] Step 2: After the coolant flows from the water cooling tank, it will be discharged through multiple drain ports and enter the water cooling box again through the heat dissipation pipe, thus completing the water cooling cycle;

[0021] Step 3: When the coolant passes through the heat pipe, the heat of the coolant will be transferred to the heat dissipation fins. The heat dissipation fan can be operated to cool the heat dissipation fins. Due to heat conduction, the coolant temperature can be effectively reduced to ensure the water cooling effect.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The present invention can realize water cooling circulation in the injection mold and the water cooling box by arranging a water cooling flow groove in the injection mold, and cooperating with the water cooling box, water pump, water pipe and other components of the water cooling mechanism, so as to quickly cool the fresh air air conditioner shell and facilitate demoulding. At the same time, when the water cooling circulation is carried out, the coolant flows back into the water cooling box from the heat dissipation pipe, and the heat dissipation pipe structure cooperates with the heat dissipation fan to effectively cool the coolant and conduct heat, thereby ensuring that the coolant will not be heated to a high temperature and ensuring the water cooling effect.
