Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold built-in spray nozzle. Background Art

[0002] The die-casting mold includes a slider, a core puller and other structures. The spraying of release agent in production plays a key role in mold temperature and demoulding. However, since the bottom of the pull-out slider in the mold is relatively hidden, the spraying may not be in place, which will affect the demoulding effect of the pull-out slider. The existing mold built-in spray nozzle has certain problems when used and still needs to be improved.

[0003] For example, a mold built-in spray nozzle disclosed in the utility model with authorization announcement number CN218139302U comprises a cavity plate and a slider, a first groove is provided on the cavity plate; a spray pipe is provided in the first groove; a spray block is rotatably connected to the top of the spray pipe; a first cavity is provided in the spray block, a rotating part is provided in the spray pipe, a group of spray heads are fixedly connected to the spray block, the spray heads and the first cavity are interconnected, the demoulding agent enters the first cavity and is then sprayed out through the spray head of the spray block, and then the bottom end of the slider is sprayed, when the demoulding agent is sprayed out from the spray pipe, the spraying power of the demoulding agent will drive the threaded blades to rotate, and then drive the rotating shaft to rotate, because the rotating shaft and the spray block are fixedly connected to each other, the rotation of the rotating shaft will drive the spray block and the cleaning brush to rotate, and then complete the uniform and comprehensive spraying and coating of the bottom of the slider.

[0004] When the device is in use, the release agent is first sprayed on the bottom wall of the slider through the nozzle, and then the release agent sprayed on the bottom wall of the slider is evenly spread by the rotating cleaning brush. However, the cleaning brush needs to be rotated and can only be maintained by continuously spraying the release agent. Spraying too much release agent will cause a waste of release agent. When the release agent is not sprayed, the cleaning brush cannot maintain a rotating state, thereby affecting the cleaning brush's effect of evenly spreading the release agent sprayed on the bottom wall of the slider. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a mold-built-in spray nozzle, which can solve the problem that the cleaning brush needs to be rotated by continuously spraying a release agent to maintain it, and spraying too much release agent will cause a waste of the release agent. When the release agent is not sprayed, the cleaning brush cannot maintain a rotating state, thereby affecting the technical problem of the cleaning brush being able to evenly apply the release agent sprayed on the bottom wall of the slider.

[0008] As an optimal technical solution of the utility model, the bottom end of the rotating spray pipe is connected to a fixed spray pipe through a limiting connection block for limited rotation, and one end of the fixed spray pipe away from the limiting connection block is connected to a release agent loading box.

[0009] As a preferred technical solution of the utility model, the surface of the adjusting button is provided with a rough texture for increasing the friction between the hand and the adjusting button.

[0010] As a preferred technical solution of the utility model, a cavity for loading a release agent is provided in the spray head.
