Technical Field
[0001] This utility model relates to the field of injection molding part spraying technology, specifically to a rotatable spraying fixture for injection molding parts. Background Technology
[0002] Injection molding is a method of shaping industrial products, and injection molding machines are the main molding equipment that uses plastic molds to make plastic products of various shapes from thermoplastic or thermosetting plastics. Spraying is a coating method that uses a spray gun or disc atomizer to disperse the paint into uniform and fine droplets with the help of pressure or centrifugal force and apply it to the surface of the object to be coated. Injection molding spraying is a processing method that uses a spray gun to atomize paint and coat it onto the surface of the injection molded part.
[0003] In existing technologies, some spraying fixtures used for injection molded parts are mostly stationary during actual use, and each spraying can only cover one side. This results in having to turn to the other side after one side is finished, which undoubtedly increases the number of steps for workers, greatly reduces the efficiency of spraying injection molded parts, prolongs the spraying time, and has low flexibility and poor practicality. In view of this, we propose a rotatable spraying fixture for injection molded parts to solve the above problems. Utility Model Content

[0032] Please see Figures 1-4 This utility model provides a technical solution: a rotatable spraying fixture for injection molded parts, including a worktable 1. The upper surface of the worktable 1 is provided with a movable plate 2 for supporting the workpiece. The movable plate 2 is rotatably fitted with a placement platform 3 for placing the workpiece.

The two connecting plates 21 are respectively threaded onto the two opposite threads of the bidirectional threaded rod 20. The two connecting plates 21 are respectively slidably connected inside the two through slots 19. The rotation of the bidirectional threaded rod 20 can drive the connecting plates 21 to move, thereby driving the protective doors 22 to move.
[0040] The horizontal plate of the gantry frame 15 is fixedly fitted with a limiting rod 23 to ensure the sliding stability of the connecting plate 21.

The two ends of the limiting rod 23 are fixedly connected to the inner walls of the two through slots 19 respectively. The two connecting plates 21 are slidably fitted on the outside of the limiting rod 23.
[0041] Among them, the first motor 7, the second motor 13 and the third motor 24 are also equipped with power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail in this article.
[0042] Working principle:
[0043] When using this rotatable spraying fixture for injection molded parts, the operator places the workpiece to be sprayed on the upper side of the placement platform 3, and then turns on the switch of the second motor 13. The output shaft of the second motor 13 and the coupling drive the threaded rod 11 to rotate. The rotation of the threaded rod 11 and the cooperation of the guide block 12 drive the moving plate 2 to move on the surface of the worktable 1. The movement of the moving plate 2 drives the placement platform 3, the rotating column 8 and the rectangular block 9 to move. At this time, the rectangular block 9 will slide inside the first limiting groove 5. After the placement platform 3 moves to the lower side of the gantry 15 and aligns with the nozzle 18, the rectangular block 9 will enter the interior of the second limiting groove 6, and the placement platform 3, the rotating column 8 and the rotating base 4 will be on the same axis.
[0044] Then, start the electric push rod 16. The movement of the telescopic end of the electric push rod 16 will make the clamping block 25 and the workpiece clamp together, thus fixing the workpiece. Then, turn on the switch of the third motor 24. The output shaft of the third motor 24 and the coupling will drive the rotation of the bidirectional threaded rod 20. The rotation of the bidirectional threaded rod 20 will drive the two connecting plates 21 to slide inside the two through slots 19 respectively. The moving interface of the connecting plate 21 will drive the protective door 22 fixedly connected at both ends to move until the four protective doors 22 form a closure of the gantry frame 15, thereby preventing splashing onto the workers during the subsequent spraying process.
[0045] Subsequently, the switch of the first motor 7 is turned on. The output shaft of the first motor 7 and the coupling can drive the rotation of the rotating base 4. Since the rectangular block 9 is inside the second limiting groove 6, the rotation of the rotating base 4 will drive the rectangular block 9 to rotate. The rotation of the rectangular block 9 will drive the rotating column 8 and the placement table 3 to rotate, thus realizing the rotation of the workpiece. At the same time, since the clamping block 25 is in a clamping state against the workpiece at this time, and the clamping block 25 is rotatably connected to the telescopic end of the electric push rod 16, the clamping block 25 will also rotate, thus realizing the all-round spraying of the workpiece.
[0046] After the spraying is completed, the third motor 24 opens the protective door 22 again, and then the second motor 13 is started. At this time, the workpiece that has been sprayed will move out of the gantry 15, while another workpiece to be processed will enter the outside of the gantry 15. At this time, when the workpiece that has been sprayed is unloaded, the spraying work of the other workpiece can be started, thus realizing the continuity of the spraying work.
[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
