Embodiment 1

[0032] refer to Figure 1-2 , a spray gun for improving the service life of mold paint in metal mold casting, including a gun body 1, a paint connection structure 2, an air intake adjustment structure 3 and a central control device 4, and the paint connection structure 2 is provided with the central control device 4 The matched infrared ranging sensor 19, the bottom end of the gun body 1 is provided with an air inlet 5, the top end of the gun body 1 is provided with a paint inlet 6, and the end of the gun body 1 away from the air inlet 5 is provided. There is a nozzle 7, the air inlet 5 and the nozzle 7 are connected by an air intake pipe 8, an auxiliary air pipe 9 is arranged between the air intake pipe 8 and the paint connection structure 2, and the interior of the central control device 4 An intelligent control system is provided, the paint connection structure 2 is installed at the paint inlet 6, the air intake adjustment structure 3 is installed at the air inlet 5, and th...

Embodiment 2

[0039] refer to Figure 1-3 , on the basis of the first embodiment, the paint connection structure 2 includes a fixed seat 10 , a connecting seat 11 is embedded in the interior of the fixed seat 10 , and the interior of the connecting seat 11 is provided with the auxiliary gas pipe 9 . The matching functional seat 12, the bottom surface of the functional seat 12 is flush with the ground of the connecting seat 11, the top surface of the functional seat 12 is 2-4 cm away from the top surface of the connecting seat 11, and the functional seat 12 A connecting hole 13 is opened inside.

[0040] Specifically, the connection hole 13 is an N-shaped structure, and a spare hole 14 is opened on one side of the connection hole 13 to match the functional seat 12 , and the spare hole 14 communicates with the connection hole 13 . The connecting holes 13 can be arranged to open a plurality of connecting holes 13 at equal distances within the technological scope of the functional base.

Embodiment 3

[0044] refer to Figure 1-3 , on the basis of Embodiment 1 or Embodiment 2, the air intake adjustment structure 3 includes an adjustment seat 16 , and a branch pipe 17 is arranged inside the adjustment seat 16 , and the branch pipe 17 is in phase with the air intake pipe 8 . connect.

[0045] Specifically, the outer wall of the adjustment seat 16 is provided with a blocking buckle 18 that cooperates with the branch pipe 17 and the intake pipe 8 , and the connection between the branch pipe 17 and the intake pipe 8 is located in the auxiliary gas pipe 9 is above the connection with the intake pipe 8.

[0046] It is not difficult to see from the above design that the air intake adjustment structure 3 can play the role of replacing and enhancing the air inlet 5. By setting up the branch pipe 17, when the high-pressure air pipe is connected, the port of the branch pipe 17 and the port of the air inlet 5 can both carry out air flow, forming two air flow paths that can be backflowe...

Abstract

The invention discloses a spray gun capable of prolonging the service life of mold paint in metal mold casting, and belongs to the field of spray guns, the spray gun comprises a gun body, a paint connecting structure, an air inlet adjusting structure and a central control device, an air inlet is formed in the bottom end of the gun body, a paint inlet is formed in the top end of the gun body, and a nozzle is arranged at the end, away from the air inlet, of the gun body; the air inlet is connected with the nozzle through an air inlet pipe, an auxiliary air pipe is arranged between the air inlet pipe and the coating connecting structure, and an intelligent regulation and control system is arranged in the central control device. When the spray gun is started, the introduced gas not only carries the coating to be sprayed out, but also drives the coating in the tank to be stirred, so that the components of the coating are uniform, the distance parameter between a measured object and the spray gun can be obtained through the temperature and distance measurement function of the spray gun equipment, and the water content ratio parameter of the coating is combined; the coating can be prevented from covering the spray gun for the second time under the condition that the coating is not dried, the service life of the coating is greatly prolonged, and automatic spraying can be achieved.

Description

technical field [0001] The invention relates to the technical field of spray guns, in particular to a spray gun for improving the service life of mold coatings in metal mold casting. Background technique [0002] With the development of "lightweight" automobiles, aluminum alloy castings are widely used. However, in the casting process, the life of the metal mold coating affects the yield and efficiency of the casting. If the paint peels off quickly during use, the short life will bring the following problems: [0003] The thermal insulation changes, the solidification gradient of the mold changes, and the shrinkage porosity in the casting increases; the fluidity of the metal decreases, and the tendency of insufficient pouring increases; during the casting process, the paint is sprayed, which affects the process stability and reduces production. efficiency and improve the labor intensity of workers. [0004] For the above problems, it is found that in addition to the desig...
