Description

Technical Field

[0001] This invention belongs to the field of positioning mechanism technology, and specifically relates to a positioning adjustment device for mold etching. Background Technology

[0002] Mold etching is a crucial step in mold manufacturing. It primarily uses chemical etching to create pre-defined textures, patterns, or structures on the mold surface, and is widely used in the precision processing of plastic and metal molds. Traditional mold etching equipment often relies on manual loading and unloading, and manual alignment. This method is not only inefficient but also suffers from poor positioning accuracy, easily leading to etching position misalignment and inconsistent processing, significantly reducing the yield of mold etched products.

[0003] Meanwhile, the existing etching equipment suffers from poor conveyor structure stability, making it prone to shifting and shaking during mold transport. Furthermore, dust and impurities easily adhere to the mold surface, and these residues directly affect the etching smoothness and effect. In addition, traditional positioning structures are mostly fixed limiting structures, unable to flexibly adjust the positioning spacing according to molds of different sizes, resulting in poor adaptability and difficulty in meeting the high-precision etching needs of diverse molds. Summary of the Invention

[0004] The purpose of this invention is to provide a positioning and adjustment device for mold etching that is simple in structure and reasonably designed in order to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A positioning and adjustment device for mold etching includes an etching machine body, a conveying mechanism for automatically feeding the mold is provided on the front side of the etching machine body, a positioning mechanism is provided on the conveying mechanism, and a cleaning mechanism is provided on the right side of the positioning mechanism.

[0007] Preferably, the etching machine body is provided with several maintenance doors, the bottom of the etching machine body is provided with self-locking casters, and the four corners of the bottom of the etching machine body are respectively fixedly installed with anchor bolts.

[0008] Preferably, the conveying mechanism includes two side plates symmetrically arranged on the top left side of the etching machine body, a rotating shaft is rotatably mounted between the two side plates, a rotating roller is fixedly sleeved on the outside of the rotating shaft, a conveying roller is sleeved on the outside of the two rotating rollers, and a triangular iron is fixedly connected between the etching machine body and the side plates.

[0009] Preferably, a servo motor is fixedly installed on the front side plate, the output end of the servo motor is fixedly connected to the front end of one of the rotating shafts, and the rear ends of the two rotating shafts rotate through the side plate and are respectively fixedly sleeved with a No. 1 synchronous pulley, and the two No. 1 synchronous pulleys mesh with a No. 1 synchronous belt.

[0010] Preferably, the cleaning mechanism includes ear plates symmetrically fixedly installed on the top right side of the side plate, a cleaning brush that rotates through the two ear plates, a second synchronous pulley fixedly sleeved on the rear center of the cleaning brush and one of the rotating shafts, and a second synchronous belt meshing between the two second synchronous pulleys.

[0011] Preferably, the positioning mechanism includes a fixed plate fixedly installed on the side plate, a cylinder fixedly installed on the top of the fixed plate, a protective box fixedly installed on the output ends of the two cylinders, a bidirectional lead screw rotatably installed inside the protective box, and a handwheel fixedly installed after the front end of the bidirectional lead screw rotates through the protective box.

[0012] Preferably, the bottom of the protective box is provided with a guide groove, a movable plate is threadedly connected to the bidirectional screw, a movable rod is fixedly installed at the bottom of the movable plate, and the movable rod is slidably connected inside the guide groove.

[0013] Preferably, a mounting plate is fixedly installed at the bottom of the movable rod, and several guide rollers are evenly rotated and installed at the bottom of the mounting plate.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. Unlike existing technologies, this invention sets up a conveying mechanism and uses a servo motor in conjunction with a synchronous pulley and synchronous belt drive to drive the conveyor belt to run stably, thereby realizing automated mold feeding and conveying, replacing manual loading and unloading. The cleaning brush rotates synchronously by relying on the power of the conveying mechanism, automatically cleaning dust and impurities on the mold surface during the mold conveying process, avoiding impurities from affecting the etching processing accuracy. No additional cleaning power components are required, and the equipment structure is more streamlined and energy consumption is lower.

[0016] 2. Unlike existing technologies, this invention features an adjustable positioning mechanism. Driven by a handwheel, a bidirectional lead screw rotates, allowing for flexible adjustment of the distance between the two moving plates. This adapts to the positioning needs of molds with different widths, offering strong versatility. Combined with a cylinder, the entire positioning structure can be raised and lowered, accommodating molds of varying thicknesses and providing extremely high positioning flexibility. A guide roller at the bottom of the positioning mechanism not only limits and positions the mold but also rotates synchronously with the mold during transport, preventing rigid limiting from causing jamming or scratches and ensuring smooth mold transport. Simultaneously, it effectively guarantees the alignment accuracy of the mold transport, improving the consistency and yield of the etching process. Attached Figure Description

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example: Please refer to Figure 1 A positioning and adjustment device for mold etching includes an etching machine body 1. A conveying mechanism 5 for automatic mold feeding is provided on the front side of the etching machine body 1. The conveying mechanism 5 is used to automatically complete the mold feeding and conveying. A positioning mechanism 7 is provided on the conveying mechanism 5 for precise alignment and limiting during the mold conveying process, ensuring that the mold accurately enters the etching station for processing. A cleaning mechanism 6 is provided on the right side of the positioning mechanism 7. Several maintenance doors 4 are provided on the etching machine body 1. When the equipment malfunctions or needs regular maintenance, the maintenance doors 4 can be opened to inspect and maintain the internal electrical and etching components. The operation is convenient. A self-locking universal wheel 3 is provided at the bottom of the etching machine body 1. Anchor bolts 2 are fixedly installed at the four corners of the bottom of the etching machine body 1.

[0025] Please see Figure 1 , Figure 2 and Figure 3The conveying mechanism 5 includes two side plates 51 symmetrically arranged on the top left side of the etching machine body 1. A rotating shaft 54 ​​is rotatably mounted between the two side plates 51. A rotating roller is fixedly sleeved on the outside of the rotating shaft 54. A conveying roller 55 is sleeved on the outside of the two rotating rollers. A triangular iron 52 is fixedly connected between the etching machine body 1 and the side plates 51 to form a stable triangular support structure, which effectively enhances the load-bearing capacity and installation stability of the side plates 51 and avoids deformation and loosening of the side plates 51 during long-term conveying operations. A servo motor 53 is fixedly mounted on the front side plate 51 as the active power source of the conveying mechanism 5. The output end of the servo motor 53 is fixedly connected to the front end of one of the rotating shafts 54. The rear ends of the two rotating shafts 54 rotate through the side plates 51 and are respectively fixedly sleeved with a first synchronous pulley 56. The two first synchronous pulleys 56 mesh with a first synchronous belt 57.

[0026] Please see Figure 2 and Figure 3 The cleaning mechanism 6 includes ear plates 61 symmetrically fixedly installed on the top right side of the side plate 51. A cleaning brush 62 is inserted through the two ear plates 61 and rotates together. The cleaning brush 62 can adhere to the upper surface of the mold to complete the cleaning operation. A second synchronous wheel 64 is fixedly sleeved on the rear center of the cleaning brush 62 and one of the rotating shafts 54. A second synchronous belt 63 meshes between the two second synchronous wheels 64. Relying on the power of the servo motor 53 of the conveying mechanism 5, while the rotating shaft 54 ​​rotates to convey the mold, the cleaning brush 62 is driven to rotate in the opposite direction through the second synchronous belt 63 to perform all-round cleaning of the mold surface that has been conveyed, removing dust and particulate impurities attached to the mold surface, avoiding etching defects caused by impurities from the source, and improving the etching processing quality.

[0027] Please see Figure 1 , Figure 4 and Figure 5 The positioning mechanism 7 includes a fixed plate 71 fixedly installed on the side plate 51. The positioning mechanism 7 is used for precise positioning during the mold conveying process and is suitable for molds of different specifications. A cylinder 72 is fixedly installed on the top of the fixed plate 71. A protective box 74 is fixedly installed on the output end of the two cylinders 72. The protective box 74 can be raised and lowered as a whole by extending and retracting the cylinders 72, flexibly adjusting the height of the positioning structure to meet the positioning requirements of mold workpieces of different thicknesses. A bidirectional lead screw 78 is rotatably installed inside the protective box 74. A handwheel 73 is fixedly installed after the front end of the bidirectional lead screw 78 rotates through the protective box 74. A guide groove 79 is opened at the bottom of the protective box 74. A moving plate 75 is threadedly connected to the bidirectional lead screw 78. A moving rod is fixedly installed at the bottom of the moving plate 75. The moving rod is slidably connected inside the guide groove 79. An installation plate 76 is fixedly installed at the bottom of the moving rod. Several guide rollers 77 are evenly rotatably installed at the bottom of the installation plate 76.

[0028] It should be noted that this positioning and adjustment device for mold etching is used as follows: First, the machine body is leveled and fixed using anchor bolts 2. According to the thickness of the mold to be processed, cylinder 72 is activated to adjust the overall height of the protective box 74 so that the guide roller 77 is adapted to the mold thickness. Then, the handwheel 73 is rotated to drive the bidirectional lead screw 78 to rotate, which drives the two moving plates 75 to move relative to each other, adjusting the distance between the two guide rollers 77 to match the width of the mold, thus completing the positioning parameter adjustment. The mold to be etched is placed at the left end of the conveying roller 55, and the servo motor 53 is started to drive the conveying roller 55 to move the mold to the right at a uniform speed through synchronous transmission. During the mold conveying process, the cleaning brush 62 rotates synchronously to clean the impurities on the mold surface. Then, the mold passes through the positioning mechanism 7, and the two guide rollers 77 center and limit the mold to ensure that the mold is accurately aligned and enters the etching station inside the etching machine body 1, completing the automated feeding and precise positioning etching operation.

[0029] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
