Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment, in particular to a cooling circulation equipment for a double-angle welding die. Background Technique

[0002] During the production process of refrigerator and household appliance door seals, cooling treatment needs to be carried out on them. Generally, in the welding process of door seals, the in-mold or out-of-mold air blowing cooling method has been used for a long time to cool the welding corners. The advantage of air cooling is that it can directly cool the welding corner position and can directly and quickly cool the welding corner position to solve the adhesion phenomenon.

[0003] However, in the prior art, (1) the welding die overheats after air cooling and often scalds the hands of employees; (2) the compressed air for blowing cooling is blown out through the welding die to cool the welding corner. Since the welding die is overheated, the gas blown out through the die becomes warm air at this time, thus lengthening the time of blowing cooling. Therefore, further improvement is needed.

[0004] Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop a cooling circulation equipment for a double-angle welding die. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cooling circulation equipment for a double-angle welding die to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A technical solution of a cooling circulation equipment for a double-angle welding die includes a welding die. One side of the welding die is provided with a first water inlet, and one side of the welding die is provided with a first water outlet. A first water inlet pipe is connected to the first water inlet, and a first water outlet pipe is connected to the first water outlet. A first air change valve is arranged on the first water inlet pipe, and a second air change valve is arranged on the first water outlet pipe. The first air change valve is connected to a first solenoid valve through a first pipeline, and the second air change valve is connected to a second solenoid valve through a second pipeline.

[0008] As a preferred technical solution, the welding die includes a front half die and a rear half die, and the front half die is arranged on the top surface of the rear half die.

[0009] As a preferred technical solution, a second water inlet is arranged on one side of the welding die, and a second water inlet pipe is connected to the second water inlet.

[0010] As a preferred technical solution, a second water outlet is arranged on one side of the welding die, and a second water outlet pipe is connected to the second water outlet.

[0011] As a preferred technical solution, a third water inlet pipe is connected to the first air exchange valve, and a third water outlet pipe is connected to the second air exchange valve.

[0012] As a preferred technical solution, a fourth water outlet pipe is connected to the second air exchange valve.

[0013] As a preferred technical solution, a fourth water inlet pipe is communicated with the first water inlet pipe, and a fifth water outlet pipe is vertically communicated with the first water outlet pipe.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: (1) By installing a U-shaped cooling water flow channel in the mold, cold water can circulate in the mold, and heat is transferred through the cooling water. With the cooperation of the circuit, the cooling water stops flowing in during the welding heating process, so that the temperature of the mold can be maintained between 15 and 25 degrees.

[0015] (2) Solve the problem that the welding mold is hot to the touch. Since the welding mold is baked by the heating body for a long time, the temperature of the mold surface is in the range of 60-70 degrees, and the hands of employees are often directly scalded.

[0016] (3) Considering that rust spots will be generated inside and outside the mold during long-term water circulation, which affects the use and life of the mold. Through the cooperation of the circuit, the remaining cooling water in the mold is drained to the mold collection before getting off work.

[0017] (4) The cooling circulation system can reduce the blowing time at the welding angle position of the in-mold air blowing cooling, and improve the production efficiency.

[0018] (5) Solve the problem that the chiller generates condensate due to temperature difference, which affects the generation of rust spots on the mold surface, and the generated condensate causes water droplets to fall into the electrical parts, resulting in electric leakage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The features and exemplary embodiments of various aspects of the present utility model will be described in detail below. To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present utility model can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present utility model by showing examples of the present utility model.

[0022] As Figure 1 shown, the present utility model provides a technical solution for a double-angle welding die cooling circulation device: including a welding die 1, wherein the welding die 1 includes a front half die 10 and a rear half die 11. The front half die 10 is arranged on the top surface of the rear half die 11. The welding die 1 is already filled with criss-crossing flow channels: for example, a magnetic strip surface vacuum adsorption flow channel, a gas blowing cooling flow channel in the welding angle die, etc. Moreover, a U-shaped cooling water flow channel is installed in the narrow space.

[0023] In this embodiment, a first water inlet is provided on one side of the welding die 1, and a first water outlet is provided on one side of the welding die 1. The first water inlet and the first water outlet are symmetrically arranged. At the same time, a first water inlet pipe 4 is connected to the first water inlet, and a first water outlet pipe 5 is connected to the first water outlet. Cold water enters the welding die 1 from the first water inlet pipe 4, and then flows out to the outside from the first water outlet pipe 5, so that the cold water can circulate in the die, transfer the heat through the cooling water, and thus form a closed-loop circulation system.

[0024] Among them, a first air change valve 6 is provided on the first water inlet pipe 4, and the first air change valve 6 controls the opening or closing of the first water inlet pipe 4. A second air change valve 7 is provided on the first water outlet pipe 5, and the second air change valve 7 controls the opening or closing of the second water inlet pipe 13. Moreover, both the first air change valve 6 and the second air change valve 7 are three-way air change valves. A first solenoid valve 8 is connected to the first air change valve 6 through a first pipe, and a second solenoid valve 9 is connected to the second air change valve 7 through a second pipe. The first solenoid valve 8 and the second solenoid valve 9 open or close the first air change valve 6 and the second air change valve 7. When the heating body of the double welding angle welding machine completes the heating cycle and descends, the magnetic switch at the descending position is triggered. The magnetic switch triggers the two-position three-way solenoid valves 8 and 9, and simultaneously opens the first air change valve 6 and the second air change valve 7, so that the cooling water enters the welding die 1 for cooling treatment.

[0025] In this embodiment, a second water inlet 12 is provided on one side of the welding die 1. A second water inlet pipe 13 is connected inside the second water inlet 12. The second water inlet pipe 13 is communicated with the first water inlet pipe 4. At the same time, a second water outlet 14 is provided on one side of the welding die 1. A second water outlet pipe 15 is connected inside the second water outlet 14. The second water outlet pipe 15 is communicated with the first water outlet pipe 5. Cold water can enter the welding die 1 through the second water inlet pipe 13 and be discharged from the second water outlet pipe 15. In cooperation with the first water inlet pipe 4 and the first water outlet pipe 5, the cooling efficiency of the welding die 1 is improved.

[0026] In this embodiment, a third water inlet pipe 16 is connected to the first air change valve 6. The third water inlet pipe 16 is communicated with the water chiller. At the same time, a third water outlet pipe 17 is connected to the second air change valve 7. The water in the water chiller enters the first air change valve 6 through the third water inlet pipe 16, and then is discharged to the outside through the third water outlet pipe 17. When the temperature controlled by the water chiller has a general temperature difference of 10 degrees, the equipment will generate condensate. Through the water chiller with intelligent temperature control function, the water temperature can be automatically adjusted. Usually, the cooling water temperature in the water tank is about 2 degrees lower than the ambient temperature to avoid generating condensate due to temperature difference problems, which may affect the generation of rust spots on the mold surface and cause water droplets to fall into the electrical parts, resulting in electric leakage.

[0027] In this embodiment, a fourth water outlet pipe 18 is connected to the second air change valve 7. Since the mold is made of steel, this utility model takes into account that rust spots will be generated both inside and outside the mold during the long-term operation of the mold in a water-filled environment, which affects the use and service life of the mold. Therefore, when getting off work, the first solenoid valve 8 is switched to open the two-position first air change valve 6 to lock the cooling water so that the cooling water flows into the mold, and then the second solenoid valve 9 is switched to open the two-position three-way valve so that the remaining cooling water in the mold is discharged to the waste water collection bucket through the fourth water outlet pipe 18. It takes about 10 seconds to drain the cooling water in the mold to complete this process, and this method can reduce the rusting speed of the mold.

[0028] In this embodiment, a fourth water inlet pipe 19 is communicated with the first water inlet pipe 4, and a fifth water outlet pipe 20 is vertically communicated with the first water outlet pipe 5. The fourth water inlet pipe 19 is connected to the water inlet of another set of welding die 1, and the fifth water outlet pipe 20 is connected to the water outlet of another set of welding die 1.
