Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, and particularly relates to a mold release agent spraying device for forging and pressing processing. Background Technique

[0002] Forging and pressing is the combination of forging and stamping. When the mold formed by forging and pressing processing falls off, a release agent is required. The release agent is a functional substance between the mold and the finished product. Usually, a spraying device is used to spray the release agent on the material, so that the release agent can be evenly attached to the material and improve the processing quality. When the release agent is used, a mold release agent spraying device for forging and pressing processing is needed.

[0003] According to the description in the release agent spraying equipment (authorization announcement number: CN 208853064 U) disclosed on the patent network, "The utility model relates to the technical field of spraying equipment, and discloses a release agent spraying equipment, including a main body box. A motor is fixedly installed on the top of the main body box. The output shaft of the motor penetrates and extends into the interior of the main body box. The output shaft of the motor is fixedly connected with a rotating rod through a coupling. The bottom end of the rotating rod is fixedly connected with the inner bottom wall of the main body box through a bearing. A connecting ring is fixedly connected to the outer surface of the rotating rod. Stirring rods are fixedly connected to both the left and right sides of the connecting ring. A partition board is fixedly connected to the inner wall of the main body box and on the left side of the stirring rod. A first water pump is fixedly installed at the bottom of the main body box. Water pipes are fixedly connected to both the left and right sides of the first water pump. The right water pipe penetrates the main body box and extends to the right side of the partition board. This release agent spraying equipment automatically dilutes, is simple to operate, saves time and effort, and improves work efficiency."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During the use of this utility model, the release agent and the diluent are poured into the interior of the main body box through the feed pipe. The motor drives the rotating rod to rotate, and the stirring rod on the rotating rod mixes and dilutes the release agent and the diluent in the main body box evenly. The first water pump introduces the release agent from the water pipe into the left side of the partition board. The diluted release agent on the left side of the partition board is pumped into the hose through the spraying pipe connected to the second water pump, and the material is sprayed through the nozzle, thus achieving automatic dilution. However, in actual use, the release agent and the diluent are mixed and diluted evenly in the main body box, and when discharged, they cannot be completely discharged, which will cause waste of the release agent and dry up in the main body box, making it inconvenient to clean. Secondly, the sizes of the molds are different, and the spraying ranges required are also different. When this device sprays, it cannot control the size of the spraying range according to the size of the mold. Therefore, it is necessary to improve a mold release agent spraying device for forging and pressing processing to solve the above problems. Content of the Utility Model
