[0018] The first embodiment of the present application is:

[0019] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of a spraying mechanism for automobile development molds in the first embodiment of the utility model. Figure 2 It is a structural schematic diagram of the clamping assembly of the first embodiment of the utility model.

[0020] The utility model provides a mechanism for spraying a mold for automobile development: it includes a spraying seat 101 and a support block 102, and also includes a flipping device, the flipping device includes a main shaft 103, a transmission gear 104, a driving gear 105, a connecting shaft 106, a positioning plate 107, a clamping assembly and a rotation drive assembly, the rotation drive assembly includes a rack 108 and an electric push rod 109, the clamping assembly includes a cylinder 111, a push plate 112 and a positioning rod 113, and the clamping assembly also includes an anti-slip pad 114. The above-mentioned scheme solves the problem that when the above-mentioned mechanism flips the mold, it is necessary to manually pull the rectangular block and then turn the handle to achieve flipping, but the mold needs to be flipped on multiple surfaces during spraying, and manual flipping will affect the spraying efficiency of the mold. It can be understood that this scheme can also be used to solve the problem of buffering after the mold falls.

[0021] In this embodiment, the mold is fixed by the clamping assembly, and the main shaft 103 is driven to rotate by the rotating drive assembly under the transmission engagement of the driving gear 105 and the transmission gear 104, so that the main shaft 103 drives the mold to rotate, thereby realizing automatic turning over of the mold during spraying, avoiding manual operation, and thereby improving the spraying efficiency of the mold.

[0022] The main shaft 103 is rotatably mounted on the support block 102 and passes through the support block 102. The transmission gear 104 is fixedly mounted on the main shaft 103. The positioning plate 107 is fixedly mounted on one end of the main shaft 103 away from the transmission gear 104. The clamping assembly is mounted on the positioning plate 107. The connecting shaft 106 is rotatably mounted on the support block 102. The driving gear 105 is mounted on the connecting shaft 106 through the rotating drive assembly and meshes with the transmission gear 104. The axes of the main shaft 103 and the connecting shaft 106 are parallel and are vertically oriented. The transmission gear 104 and the driving gear 105 are key-connected with the main shaft 103 and the connecting shaft 106 respectively. The cross section of the positioning plate 107 is rectangular and welded to the main shaft 103. When in use, the mold is fixed by the clamping assembly, and the main shaft 103 is driven to rotate by the rotating drive assembly under the transmission engagement of the driving gear 105 and the transmission gear 104. The main shaft 103 further drives the mold to rotate at a uniform speed through the positioning plate 107, thereby realizing automatic turning over of the mold during spraying, avoiding manual operation, and thereby improving the spraying efficiency of the mold.

[0023] Secondly, a slide groove 110 is provided on one side of the spray seat 101, and the rack 108 is slidably installed on the spray seat 101 and is located in the slide groove 110; the output end of the electric push rod 109 is fixedly connected to the rack 108, and the rack 108 is located at the bottom of the driving gear 105. The length of the rack 108 is less than the length of the slide groove 110, and the electric push rod 109 is fixed to the spray seat 101 by screws, and one side of the rack 108 is welded to the output end of the electric push rod 109. The electric push rod 109 drives the rack 108 to move along the slide groove 110. The movement of the rack 108 drives the driving gear 105 to rotate through engagement with the driving gear 105, thereby achieving a rotation effect on the driving gear 105.

[0024] Again, the cylinder 111 is fixedly mounted on the positioning plate 107; the push plate 112 is fixedly mounted on the output end of the cylinder 111; the positioning rod 113 is fixedly mounted on the push plate 112, the number of the clamping components is two groups, and they are symmetrically distributed along the center line of the positioning plate 107, the cylinder 111 is fixed to the side of the positioning plate 107 by bolts, the cross-section of the push plate 112 is rectangular, and each group of the push plates 112 is provided with two groups of the positioning rods 113. Through the setting of the positioning rods 113, the contact area with the mold can be reduced and the spraying area can be increased. The cylinder 111 drives the push plates 112 to move toward each other, so that the positioning rods 113 on both sides clamp the mold, thereby achieving a fixing effect on the mold.

[0025] Finally, the anti-skid pad 114 is fixedly installed on the positioning rod 113. The anti-skid pad 114 is made of rubber. An anti-skid pad 114 is provided at one end of each group of positioning rods 113 away from the positioning plate 107. The setting of the anti-skid pad 114 can increase the friction between the positioning rod 113 and the mold.

[0026] In this embodiment, when in use, the mold is placed between the positioning rods 113, and then the cylinder 111 is started to drive the push plates 112 on both sides to move toward each other, and the push plates 112 drive the positioning rods 113 to fix the mold, and then the mold surface can be sprayed by an external spraying device. During the spraying process, the electric push rod 109 is started at the same time to push the rack 108 to move, and the rack 108 is meshed with the driving gear 105, and drives the driving gear 105 to rotate through the connecting shaft 106. At the same time, the driving gear 105 is meshed with the transmission gear 104, and the transmission gear 104 rotates accordingly, and the transmission gear 104 drives the main shaft 103 fixedly connected to the transmission gear 104 to rotate, and the positioning plate 107 is fixedly installed on the main shaft 103. The rotation of the main shaft 103 drives the positioning plate 107 to rotate, and further drives the fixed mold to rotate at a uniform speed, so that all sides of the mold are sprayed, thereby realizing automatic turning over of the mold during spraying, avoiding manual operation, and further improving the spraying efficiency of the mold.

[0029] In this embodiment, the buffer plate 201 and the buffer spring 202 cooperate with each other to achieve a buffering effect on the mold.

[0030] Among them, the buffer spring 202 is fixedly installed on the spray seat 101 and is located on the side of the spray seat 101 close to the positioning plate 107; the buffer plate 201 is fixedly installed on the buffer spring 202, and the number of the buffer springs 202 is four groups, which are respectively distributed at the four corners of the buffer plate 201. The upper surface of the buffer plate 201 is also provided with a sponge layer. When the mold is sprayed, it falls onto the buffer plate 201.
