Description

Technical Field

[0001] The utility model relates to the technical field of release agent spraying, in particular to a release agent spraying device. Background Technique

[0002] A release agent is a type of isolation film applied between a product and a mold to prevent the formed composite product from sticking to the mold, so that the product can be easily removed from the mold, while ensuring the surface quality of the product and the integrity of the mold. Release agents are divided into two categories: internal lubricity and external lubricity. The former mainly improves the lubricity of the polymer molecules themselves, and it requires a certain degree of affinity or compatibility with the resin polymer. The latter is to improve the lubricity between the mold and the polymer. When die-casting the automotive transmission housing, it is necessary to spray a release agent in the mold to facilitate demolding.

[0003] In the prior art, the Chinese utility model content with the authorization announcement number: CN218945426U discloses an internal spraying device for steel plate release agent, including a frame. Substrates are installed on both sides of the frame. A guide rail column and a screw column are respectively installed between the opposite ends of the substrates. One end of the screw column extends out of the substrate and is equipped with a driving motor. A sliding column and a reciprocating screw rod are respectively arranged between the two sides of the guide rail column and the screw column. The two ends of the reciprocating screw rod are connected to the guide rail column and the screw column, and a fixed sleeve is installed at the end of the sliding column connected to the guide rail column. A driving mechanism is arranged between the fixed sleeve and the reciprocating screw rod for driving the reciprocating screw rod to rotate. A first sliding sleeve is installed at the end of the sliding column connected to the guide rail column. A moving seat is slidably sleeved on the sliding column. A second mounting seat is threadedly sleeved on the reciprocating screw rod. A spraying mechanism is arranged between the second mounting seat and the moving seat. This utility model is easy to adjust and convenient for internal spraying operation.

This method is applicable to the case where the inner surface is flat and the spray gun can completely cover all areas inside the steel plate. However, the inner cavities of some molds are uneven. The spray gun sprays at a fixed point and cannot completely cover, resulting in the inability to spray the release agent on some parts of the mold, making it very difficult to demold subsequently, and at the same time, it is easy to cause certain damage to the workpiece.

[0027] The first electric push rod 6 drives the double-sided rack plate 7 to perform telescopic movement. The adjusting gear 8 deflects the angle of the spray head 9, so that the spray head 9 can adjust the up and down angles, which is convenient for spraying the mold release agent on some positions that cannot be sprayed in the direct spraying area. Then, in cooperation with the lifting and rotation of the telescopic rod 5, the inner wall of the mold is sprayed all-round, improving the comprehensiveness of the mold release agent spraying and ensuring easy demolding.

[0028] The moving component 3 includes a first driving motor 31 fixed to one side of the storage box 1. A translation screw rod 32 is fixed to the output shaft of the first driving motor 31. The translation screw rod 32 rotates in the inner cavity of the storage box 1 through a bearing. The outer side of the storage bin 2 is rotatably connected to a support frame 33 through a bearing. A threaded sleeve 34 is fixedly embedded on the support frame 33. The translation screw rod 32 threadedly penetrates through the threaded sleeve 34. By driving the translation screw rod 32 to rotate with the first driving motor 31, and then threadedly connecting the support frame 33 and the translation screw rod 32 through the threaded sleeve 34, translation can be performed when the translation screw rod 32 rotates, and the position of the storage bin 2 can be adjusted.

[0029] It further includes a lifting component 12 for moving the telescopic rod 5 up and down. The lifting component 12 includes a second driving motor 121 fixed at the center of the top of the storage bin 2.

Through the displacement sensor 25, the distance between the bottom of the telescopic rod 5 and the bottom of the inner cavity of the mold can be detected to prevent the telescopic rod 5 from moving downward and damaging the mold during spraying.

[0037] During specific use, place the die-casting mold of the automotive transmission housing that needs to be sprayed with release agent on the support plate 17. Then start the second electric push rod 16. The second electric push rod 16 drives the support plate 17 to move upward to lift the mold, so that the telescopic rod 5 penetrates into the mold. Then the second drive motor 121 drives the lifting screw rod 122 to rotate. The lifting screw rod 122 adjusts the height of the telescopic rod 5 through the screw hole 123. At the same time, the first electric push rod 6 drives the double-sided rack plate 7 to move up and down. The spray head 9 is driven to swing up and down through the adjusting gear 8. Then start the delivery pump 10. The delivery pump 10 sprays the release agent in the storage tank 2 from the spray head 9 through the infusion tube 11. At the same time, the third drive motor 13 drives the drive gear 14 to rotate. The drive gear 14 drives the storage tank 2 to rotate by using the driven gear 15. At the same time, the telescopic rod 5 and the spray head 9 rotate with the rotation of the storage tank 2 to increase the spraying coverage area and spray the concave and convex positions in the inner cavity of the mold. Then the first drive motor 31 drives the translation screw rod 32 to rotate, and the support frame 33 is translated by using the thread sleeve 34 to move the spraying in the inner cavity of the mold for spraying in all directions.
