Description

Technical Field

[0001] The present application relates to the technical field of laser film production, and in particular to a rapid mold-changing device for laser film production. Background Art

[0002] In the current laser film production industry, mold changing is an indispensable part of the production process and is directly related to the stability of production efficiency and product quality. Traditional mold changing methods often rely on manual handling and manual adjustment of mold positions, which is not only labor-intensive and time-consuming, but also poses safety hazards, such as the risk of falling during mold handling. In addition, traditional mold changing methods lack effective auxiliary measures for the placement and movement of molds. The molds do not slide smoothly on the placement racks, and there are no special support and rolling structures to increase the sliding speed of the molds, resulting in slow mold access and adjustment processes, increased labor intensity of operators, and reduced production efficiency. Moreover, traditional mold changing devices are insufficient in terms of mold isolation and protection. Two or more molds are prone to collision or interference with each other, and there is a lack of effective isolation measures, which may cause damage to the molds, affecting production quality and mold service life.

[0003] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The embodiment of the present application discloses a rapid mold changing device for laser film production. Figure 1 , including a mobile frame 1, a placement frame 2 is installed on the top of the mobile frame 1, and the two sides of the top of the placement frame 2 are welded with limited edges 3 as an integral structure for protecting both sides of the laser film production mold, and the inner wall of the placement frame 2 is welded with a supporting rod 6 for supporting the bottom of the laser film production mold, and a group of guide rails 4 are symmetrically fixed on the top of the placement frame 2, and the interior of the guide rails 4 is equidistantly rotated and provided with a number of pulleys 5, which contact the laser film production mold through the pulleys 5, can assist the mold to slide, and improve the mold changing efficiency, and a group of support plates 12 are welded on the back wall of the placement frame 2, and the inner wall of the support plate 12 is connected to the cylinder 13 by screws, and the output end of the cylinder 13 is connected to the connecting piece 14.

[0020] Combine Figure 2-Figure 3 As shown, the interior of the connecting member 14 is connected to a movable rod 10, and a positioning frame 7 is installed at the top of the movable rod 10. The interior of the positioning frame 7 is provided with a group of baffles 11 for protecting the template. A fixing frame 8 is welded in the middle of the back wall of the placement frame 2, and a connecting head 9 is symmetrically fixed on the surface of the fixing frame 8. One end of the movable rod 10 is rotatably connected to the connecting head 9, and a slide 15 is opened inside the top of the movable rod 10, and a corresponding connecting rod 16 is provided for sliding inside the slide 15. The two ends of the connecting rod 16 extend to the outside of the slide 15 and are fixed to the inner wall of the connecting member 14. Therefore, as the cylinder 13 extends and contracts, the connecting member 14 will be pushed to slide in the slide 15 with the connecting rod 16, and then the movable rod 10 will be pushed to rotate and tilt outward outside the connecting head 9, and then the baffle 11 will be pushed away from the top of the laser film production mold, which is used to release the limit on the mold and facilitate the use of the mold for mold replacement. By setting multiple baffles 11, multiple laser film production molds can be separated in the middle to avoid friction and contact between multiple laser film production molds.

[0021] In the present application, limit rods for limiting the position of the baffle 11 are rotatably installed on both sides of the outer wall of the positioning frame 7. A movable cavity 17 is opened inside the positioning frame 7 to provide movable space for the baffle 11, and an inner slide groove 18 is symmetrically opened on the inner wall of the movable cavity 17. A support block 19 for supporting the baffle 11 is fixed at the bottom end of the inner wall of the inner slide groove 18. A sliding shaft 20 adapted to the inner slide groove 18 is rotatably provided inside the top of the baffle 11. When the baffle 11 is rotated outward, the sliding shaft 20 can be pushed to slide in the inner slide groove 18 until it approaches the support block 19. At this time, the support block 19 can support the bottom of the baffle 11, thereby releasing the limit on the mold and facilitating subsequent mold changing.

[0022] The implementation principle of a rapid mold-changing device for laser film production in the embodiment of the present application is as follows: when in use, the output end of the cylinder 13 contracts to work, pulling the connecting piece 14 to reset, and then the connecting rod 16 slides in the slide 15, and pulls the movable rod 10 to rotate in the connecting head 9 from an inclined shape to a vertical shape, at this time, the positioning frame 7 is pushed close to the top of the placement frame 2, and then the laser film production mold is placed on the placement frame 2, and its bottom is supported by the guide rail 4 and in contact with the pulley 5. The rolling of the pulley 5 can increase the sliding speed of the laser film production mold, which is convenient for quickly taking the laser film mold for mold change. After placement, Push the baffle 11 outward, which in turn drives the sliding shaft 20 to slide forward in the inner slide groove 18 until it is close to the inner wall of the active cavity 17. Then the baffle 11 slides out of the support block 19 and then rotates downward to approach the outer wall of the laser film mold. Then place the second mold. The baffle 11 can be used to isolate the two laser film production molds, and the limit rod on the outer wall of the rotating positioning frame 7 is used to limit the external baffle 11 to ensure that the mold will not move or shake during the production process. After placement, it can be moved by pushing the movable frame 1, which is convenient for moving between multiple laser film production equipment and improving the efficiency of mold change.
