[0027] Reference Figure 1-6 , an etching mold positioning mechanism, including an etching box 1 and a storage box 2, the side wall of the etching box 1 is opened, a placing plate 5 and a connecting plate 6 are arranged inside the etching box 1, the placing plate 5 and the connecting plate 6 are placed up and down, and a connecting column 8 is fixedly installed between the placing plate 5 and the connecting plate 6, a push rod 14 is uniformly slid through the surface of the placing plate 5, a connecting block 16 is fixedly installed at the bottom of the push rod 14, a spring 15 is sleeved on the surface of the push rod 14, and the two ends of the spring 15 are respectively fixedly connected to the connecting block 16 and the placing plate 5, the surface of the connecting plate 6 is uniformly provided with jacks that match the size of the connecting block 16, and a limiting mechanism for limiting the connecting block 16 is arranged inside the connecting plate 6. When in use, the mold is first placed on the push rod The surface of 14 is pressed, and then the mold is pressed downward. The ejector pin 14 in contact with the mold will be forced to move downward until the bottom of the corresponding ejector pin 14 is inserted into the socket of the connecting plate 6. Then the limiting mechanism is used to limit and fix the ejector pin 14 of this part so that it cannot move up. At this time, the ejector pin 14 that is not pressed downward remains in its original state, so that the top of the connecting plate 6 forms a groove that can just accommodate the mold by utilizing the concave-convex shape of the ejector pin 14. Therefore, when etching the subsequent mold, it only needs to be placed in the groove to achieve the positioning effect. There is no need to perform clamping operation when placing each mold, which is convenient for use and convenient for adapting to positioning of multiple molds, thereby improving convenience of use.

[0028] Furthermore, a connecting pipe 3 is fixedly installed on the top wall of the etching box 1, and nozzles are evenly arranged on the bottom of the connecting pipe 3. The connecting pipe 3 passes through the etching box 1 upward and is inserted into the interior of the storage box 2. During the etching process, the etching liquid in the storage box 2 can be directly sprayed on the surface of the mold using the connecting pipe 3 and the nozzle.

[0029] Furthermore, two sliding columns 12 are fixedly installed inside the etching box 1, and two sliding holes 9 are opened on the surface of the connecting plate 6. The connecting plate 6 is slidably connected to the etching box 1 through the sliding columns 12 and the sliding holes 9. By setting the sliding columns 12, the entire connecting plate 6 and the placement plate 5 can be pulled out, so as to facilitate the placement of the mold and the operation of the limiting mechanism.

[0030] Furthermore, the limiting mechanism includes a limiting frame 10, a fixed block is fixedly installed on the top of the limiting frame 10, a screw 11 is threaded through the surface of the fixing block, a slide groove 7 is provided at the bottom of the connecting plate 6, the limiting frame 10 is slidably connected to the inside of the slide groove 7, the screw 11 is rotatably connected to the inside of the connecting plate 6, and one end of the screw 11 rotates and penetrates the connecting plate 6, the limiting frame 10 includes two vertical rods 102 and a cross rod 101, the cross rod 101 is evenly arranged between the two vertical rods 102, and the side wall of the connecting block 16 is provided with a card groove 17 that is adapted to the size of the cross rod 101. When the limiting mechanism is in use, after the connecting block 16 corresponding to the top rod 14 is inserted into the socket of the connecting plate 6, the screw 11 is manually rotated, and the rotation of the screw 11 will drive the fixed block and the limiting frame 10 to move, thereby utilizing the cross rod 101 in the limiting frame 10 to be stuck in the card groove of the connecting block 16 to limit the docking block 16.

[0031] Furthermore, a limiting block 13 is fixedly installed on the surface of the push rod 14 near the top. By setting the limiting block 13, the push rod 14 will be restricted by the limiting block 13 after moving down to a fixed depth and cannot move down. At this time, the push rod 14 will protrude a part of the top of the placement plate 5, so that there is a certain space between the mold and the placement plate 5 after the mold is placed, thereby preventing the etching liquid from flowing onto the placement plate 5 and causing contact with the bottom of the mold to affect the etching of the mold.

[0032] Furthermore, a sealing plate 4 matching the opening size of the etching box 1 is fixedly installed on the side walls of the placement plate 5 and the connecting plate 6, and a handle is fixedly installed on the side wall of the sealing plate 4. By setting the sealing plate 4, the etching box 1 can be closed during the etching process to prevent the etching liquid from splashing outside and affecting the operator.

[0033] In summary, during use, the mold is first placed on the surface of the ejector pin 14, and then the mold is pressed downward. The ejector pin 14 in contact with the mold will be forced to move downward until the bottom of the corresponding ejector pin 14 is inserted into the insertion hole of the connecting plate 6, and then the limiting mechanism is used to limit and fix the ejector pin 14 of this part so that it cannot move up. At this time, the ejector pin 14 that is not squeezed downward remains in its original state, so that the top of the connecting plate 6 forms a groove that can just accommodate the mold by utilizing the different extension lengths of the ejector pin 14. Therefore, when etching the subsequent mold, it only needs to be placed in the groove to achieve the positioning effect. There is no need to clamp each mold when placing it, which is convenient for use and convenient for adapting to the positioning of multiple molds, thereby improving the convenience of use. During the etching process, the etching liquid in the storage box 2 can be directly sprayed on the surface of the mold using the connecting pipe 3 and the nozzle. By setting the sliding column 12, the entire connecting plate 6 and the placement plate 5 can be pulled out, so as to facilitate the placement of the mold and the operation of the limiting mechanism. When the limiting mechanism is in use, after the connecting block 16 corresponding to the ejector rod 14 is inserted into the jack of the connecting plate 6, the screw rod 11 is manually rotated. The rotation of the screw rod 11 will drive the fixed block and the limiting frame 10 to move, so that the cross bar 101 in the limiting frame 10 is stuck in the card slot of the connecting block 16 to limit the docking block 16. By setting the limiting block 13, the ejector rod 14 will be restricted by the limiting block 13 after moving down to a fixed depth and cannot move down. At this time, the ejector rod 14 will protrude a part of the top of the placement plate 5, so that there is a certain space between the mold and the placement plate 5 after the mold is placed, thereby avoiding the etching liquid from flowing onto the placement plate 5 and contacting with the bottom of the mold to affect the etching of the mold. By setting the sealing plate 4, the etching box 1 can be closed during the etching process to avoid the etching liquid splashing outside and affecting the operator.
