Description

Technical Field

[0001] This utility model relates to the field of injection molding part spraying technology, and more specifically, to a spraying device for the surface of injection molding parts. Background Technology

[0002] Injection molded parts are various plastic products formed by injecting molten plastic raw materials into a mold cavity of a specific shape using the injection molding process, followed by cooling and solidification. They are widely used in the automotive, electronics, home appliance, and medical device industries, such as automotive interior parts, electronic device housings, and home appliance accessories. Because injection molded parts may have defects such as mold marks, burrs, and color differences on their surface after molding, and because the plastic itself has poor weather resistance, wear resistance, and corrosion resistance, it cannot meet the performance and appearance requirements of actual use. Therefore, surface coating treatment is necessary for injection molded parts. Spraying can form a uniform coating on the surface of injection molded parts, which not only improves the appearance and texture and covers molding defects, but also enhances the weather resistance, scratch resistance, and chemical stability of the injection molded parts, extending their service life.

[0003] A search revealed Chinese patent application number CN202321766245.6, which discloses a surface spraying mechanism for injection molded parts. The mechanism includes a spraying mechanism body and a protective layer. The top of the protective layer is fixedly connected to the bottom of the spraying mechanism body. A motor is fixedly installed on the rear side of the inner wall of the spraying mechanism body. Several motors are arranged and distributed at equal intervals. An adapter post is provided on the front of the motor. An anti-splash component is fixedly connected to the bottom of the inner wall of the spraying mechanism body. An adjustment component is provided on the front of the adapter post. Although the aforementioned patent, by setting up a motor and adapter column, allows users to movably mount injection molded parts of different sizes onto the surface of the adapter column, and then rotating the adapter column by turning on the motor, which in turn rotates the injection molded parts movably mounted on its surface, thus solving the problem that the device cannot adjust the orientation of the injection molded parts and therefore can only spray the surface of the injection molded parts, not the bottom, thus lacking practicality, and achieving the effect of increasing the spraying area, the following shortcomings still exist in use: 1. In the injection molded part clamping process, it is necessary to... 1. Manually pushing the throttle to move the adapter cylinder to fix the injection molded part is cumbersome and takes a long time to prepare for clamping, which affects the overall spraying efficiency. In addition, it is difficult to accurately control the clamping force during manual adjustment, and the injection molded part is easily damaged due to over-adjustment. There is no effective protection mechanism for the injection molded part. 2. Although a splash guard and a collection box are set up to recover excess paint, the diversion effect of the first and second inclined plates alone cannot completely remove the paint residue in the splash guard. A large amount of paint remains in the splash guard structure and is difficult to recover, resulting in paint waste, reduced resource utilization, and failure to meet the needs of high-efficiency and energy-saving production.

[0004] Therefore, there is an urgent need for a spraying equipment for the surface of injection molded parts to solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A spraying device for the surface of injection molded parts includes a support body and further includes: A spraying frame is fixedly connected to the inner wall of the support body, and a collection box is fixedly connected to the side wall of the spraying frame, and a bottom plate is fixedly connected to the side wall of the collection box. The sliding frame is slidably connected to the top of the spraying frame through sliding grooves evenly opened on the top of the spraying frame. The side wall of the sliding frame is provided with a linkage component, and the side wall of the sliding frame is also fixedly connected with an adapter cylinder. The automatic protection component is driven, including: Drive motor A is fixedly connected to the bottom of the base plate, and a drive column is fixedly connected to the output end of drive motor A; A cross-shaped column is fixedly connected to the top of the drive column; The driven column is slidably connected to the outer wall of the cross column, and both the driven column and the outer wall of the drive column are fixedly connected to a limit plate; A strong spring is sleeved on the outer wall of the driven column and the cross column, and the strong spring is fixedly connected to the limiting plate; The drive bevel gear is fixedly connected to the top wall of the driven column; A vibration-assisted detachment assembly is installed on the inner wall of the spray booth to prevent liquid residue.

[0007] As a preferred technical solution of this application, the linkage component includes A linkage frame is fixedly connected to the side wall of the sliding frame, and the linkage frame is slidably connected to the spraying frame; An adjusting screw is threadedly connected to the outer wall of the linkage frame, and the adjusting screw is rotatably connected to the spraying frame; The driven bevel gear is fixedly connected to the end of the adjusting screw away from the spray frame, and the outer wall of the driven bevel gear is meshed with the outer wall of the driving bevel gear.

[0008] As a preferred technical solution of this application, the vibration detachment component includes: Drive motor B is fixedly connected to the inner wall of the spraying rack, and a rotating rod is fixedly connected to the output end of drive motor B; A turntable is fixedly connected to the end of the rotating rod away from the output end of the drive motor B, and a drive plate is rotatably connected to the bottom of the turntable; A sliding plate is rotatably connected to the end of the drive plate away from the turntable, and the sliding plate is slidably connected to the spray painting frame; A splash guard is rotatably connected to the end of the slide plate away from the drive plate, and the bottom of the splash guard is fixedly connected to guide blocks symmetrically distributed about the splash guard. The outer wall of the guide blocks is slidably connected to a fixing rod that is fixedly connected to the spray frame. The splash guard is connected to the collection box. A positioning spring is sleeved on the outer wall of the fixed rod and symmetrically distributed about the fixed rod. One end of the positioning spring is fixedly connected to the side wall of the guide block, and the other end is fixedly connected to the spraying frame.

[0009] As a preferred technical solution of this application, the inner wall of the spraying frame is fixedly connected with uniformly distributed fixed frames, the inner wall of the fixed frames is fixedly connected with a drive motor C, and the output end of the drive motor C is fixedly connected with an adapter column that cooperates with the adapter cylinder.

[0010] As a preferred technical solution of this application, the top wall of the spraying rack is fixedly connected with uniformly distributed spraying boxes, the side wall of the spraying box is fixedly connected with a spraying pipe, and the end of the spraying pipe away from the spraying box is fixedly connected with a spraying head.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. By using the threaded engagement between the adjusting screw and the linkage frame, the linkage frame can be directly driven to move the sliding frame and the adapter cylinder synchronously, achieving rapid clamping of the injection molded parts. This simplifies the operation steps, shortens the preparation time for clamping the injection molded parts, and thus improves the overall spraying efficiency. At the same time, during the transmission of the adjusting screw, the meshing force of the driving bevel gear and the driven bevel gear is affected by the elasticity of the strong spring. When the clamping force on the injection molded parts is too large and exceeds the elastic force of the strong spring, the driving bevel gear and the driven bevel gear can automatically disengage, stopping the increase of clamping force. This avoids the problem of the injection molded parts being damaged due to over-adjustment, and achieves automatic protection of the injection molded parts, reducing the risk of damage to the injection molded parts. This solves the problems of the prior art where the injection molded parts need to be clamped by manually pushing and turning the handle to drive the adapter cylinder for fixation, which is complicated, requires a long preparation time, is inefficient, and is difficult to control the clamping force, easily damages the injection molded parts, and lacks a protection mechanism. 2. The vibration-dissipating component shakes off residual paint from the splash box, allowing it to flow smoothly into the collection box for recycling. This reduces paint residue in the splash-proof structure, minimizes waste, and improves resource utilization. It solves the problem in existing technologies where, despite having splash boxes and collection boxes, the flow is only guided by the first and second inclined plates, making it difficult to clean residual paint from the splash boxes, resulting in waste, low resource utilization, and difficulty in achieving high efficiency and energy saving.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0015] like Figure 1-6 As shown, this embodiment proposes a spraying device for the surface of injection molded parts, including a support body 1, and further comprising: The spraying rack 2 is fixedly connected to the inner wall of the support body 1, and a collection box 9 is fixedly connected to the side wall of the spraying rack 2. A base plate 10 is fixedly connected to the side wall of the collection box 9. The sliding frame 5 is slidably connected to the top of the spray frame 2 via the sliding grooves 4 evenly opened on the top of the spray frame 2. The side wall of the sliding frame 5 is provided with a linkage component, and the side wall of the sliding frame 5 is also fixedly connected with an adapter cylinder 18. The automatic protection component is driven, including: The drive motor A11 is fixedly connected to the bottom of the base plate 10, and the output end of the drive motor A11 is fixedly connected to the drive column 12; The cross post 13 is fixedly connected to the top of the drive post 12; The driven column 14 is slidably connected to the outer wall of the cross column 13, and the driven column 14 and the outer wall of the drive column 12 are both fixedly connected to the limit plate 15; A strong spring 16 is sleeved on the outer wall of the driven post 14 and the cross post 13, and the strong spring 16 is fixedly connected to the limiting plate 15. The drive bevel gear 17 is fixedly connected to the top wall of the driven column 14. When the drive motor A11 is started, its output end drives the drive column 12 to rotate. The drive column 12 synchronously drives the cross column 13 fixed at the top to rotate. The cross column 13 then drives the driven column 14, which is slidably connected to the outer wall, to rotate together. When the driven column 14 rotates, the drive bevel gear 17 fixed at its top wall rotates accordingly. Since the drive bevel gear 17 meshes with the driven bevel gear 8, the drive bevel gear 17 will drive the driven bevel gear 8 to rotate. If the clamping force on the injection molded part is too large and exceeds the elastic force of the strong spring 16, the driven column 14 will slide along the cross column 13, causing the drive bevel gear 17 to disengage from the driven bevel gear 8 and stop the clamping action, thereby protecting the injection molded part from damage caused by excessive extrusion force. A vibration-assisted detachment assembly is installed on the inner wall of the spray frame 2 to prevent liquid residue.

[0016] like Figure 3 As shown, in a preferred embodiment, based on the above method, the linkage component further includes... Linkage frame 6 is fixedly connected to the side wall of sliding frame 5, and linkage frame 6 is slidably connected to spray frame 2; Adjusting screw 7 is threaded to the outer wall of linkage frame 6, and adjusting screw 7 is rotatably connected to spray frame 2; Driven bevel gear 8 is fixedly connected to the end of adjusting screw 7 away from spray frame 2, and the outer wall of driven bevel gear 8 is meshed with the outer wall of driving bevel gear 17. During the sliding process of linkage frame 6, it drives sliding frame 5 fixed thereto to slide along the slide groove 4 on the top of spray frame 2. Sliding frame 5 then drives the adapter cylinder 18 fixed on the side wall to move. The adapter cylinder 18 and the adapter column 3 cooperate to achieve clamping of injection molded parts.

[0017] like Figure 5-6 As shown, in a preferred embodiment, based on the above method, the vibration detachment component further includes: The drive motor B19 is fixedly connected to the inner wall of the spray frame 2, and the output end of the drive motor B19 is fixedly connected to the rotating rod 20. Turntable 21 is fixedly connected to the end of rotating rod 20 away from the output end of drive motor B19, and drive plate 22 is rotatably connected to the bottom of turntable 21; The slide plate 23 is rotatably connected to the end of the drive plate 22 away from the turntable 21, and the slide plate 23 is slidably connected to the spray gun 2; The splash box 24 is rotatably connected to the end of the slide plate 23 away from the drive plate 22, and the bottom of the splash box 24 is fixedly connected to guide blocks 25 symmetrically distributed about the splash box 24. The outer wall of the guide block 25 is slidably connected to a fixing rod 26 fixedly connected to the spray frame 2. The splash box 24 is connected to the collection box 9. The paint shaken off by the splash box 24 flows into the collection box 9 connected to it, realizing the recycling of paint. The bottom plate 10 on the side wall of the collection box 9 provides stable support for the drive motor A11. A positioning spring 27 is sleeved on the outer wall of the fixed rod 26 and symmetrically distributed about the fixed rod 26. One end of the positioning spring 27 is fixedly connected to the side wall of the guide block 25, and the other end is fixedly connected to the spray frame 2. During the spraying process, the drive motor B19 of the vibration and detachment component is started, and its output end drives the rotating rod 20 to rotate. The rotating rod 20 drives the turntable 21 fixed at the end to rotate. The turntable 21 pushes the drive plate 22 rotatably connected at the bottom to move. When the drive plate 22 moves, it pushes the slide plate 23 rotatably connected to it to slide along the spray frame 2. The slide plate 23 drives the anti-splash box 24 rotatably connected at the end to move. The guide block 25 at the bottom of the anti-splash box 24 slides along the fixed rod 26. The positioning spring 27 on the outer wall of the fixed rod 26 deforms. Under the elastic force of the positioning spring 27, the anti-splash box 24 vibrates and shakes off the residual paint inside.

[0018] like Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the inner wall of the spraying frame 2 is further provided with uniformly distributed fixing frames 31, the inner wall of the fixing frames 31 is fixedly connected with a drive motor C32, and the output end of the drive motor C32 is fixedly connected with an adapter column 3 that cooperates with the adapter cylinder 18. When the drive motor C32 is started, its output end drives the adapter column 3 to rotate, and the adapter column 3 synchronously drives the clamped injection molded part to rotate, so as to ensure the uniformity of spraying the injection molded part.

[0019] like Figure 2 As shown, in a preferred embodiment, based on the above method, the top wall of the spray frame 2 is further provided with uniformly distributed spray boxes 28, the side wall of the spray box 28 is fixedly connected with a spray pipe 29, and the end of the spray pipe 29 away from the spray box 28 is fixedly connected with a spray head 30. When the spray box 28 on the top wall of the spray frame 2 is opened, the paint is transported to the spray head 30 through the spray pipe 29, and the spray head 30 performs spraying operation on the rotating injection molded part.

[0020] Specifically, when using the spraying equipment for injection molded parts: before starting the equipment, the injection molded part to be sprayed is placed between the adapter column 3 and the adapter cylinder 18 to complete the initial placement of the injection molded part, laying the foundation for the subsequent clamping and spraying process; the drive motor A11 is started, and its output end drives the drive column 12 to rotate. The drive column 12 synchronously drives the cross column 13 fixed at the top to rotate, and the cross column 13 drives the driven column 14 slidably connected to the outer wall to rotate together; when the driven column 14 rotates, the drive bevel gear 17 fixed at its top wall rotates accordingly. Since the drive bevel gear 17 meshes with the driven bevel gear 8, the drive bevel gear 17... This will drive the driven bevel gear 8 to rotate; when the driven bevel gear 8 rotates, the adjusting screw 7 fixedly connected to it rotates synchronously, and the adjusting screw 7 performs threaded movement on the outer wall of the linkage frame 6, pushing the linkage frame 6 to slide along the spray frame 2; during the sliding process of the linkage frame 6, it drives the sliding frame 5 fixed to it to slide along the slide groove 4 on the top of the spray frame 2, and the sliding frame 5 in turn drives the adapter cylinder 18 fixed on the side wall to move, and the adapter cylinder 18 cooperates with the adapter column 3 to achieve clamping of the injection molded part; if the clamping force on the injection molded part is too large and exceeds the elastic force of the strong spring 16, the driven column 14 will slide along the cross column 13, so that the driving bevel gear 17 and the driven bevel gear 14 will move together. The bevel gear 8 disengages, stopping the clamping action and protecting the injection molded part from damage due to excessive extrusion pressure. The drive motor C32 on the inner wall of the fixed frame 31 is activated, its output driving the adapter column 3 to rotate. The adapter column 3 synchronously drives the clamped injection molded part to rotate. Simultaneously, the spray box 28 on the top wall of the spray frame 2 is opened, and paint is delivered to the spray head 30 via the spray pipe 29. The spray head 30 performs spraying operations on the rotating injection molded part. During spraying, the drive motor B19 of the vibration detachment assembly is activated, its output driving the rotating rod 20 to rotate. The rotating rod 20 drives the turntable 21 fixed at its end to rotate, and the turntable 21 pushes the bottom rotating... The drive plate 22, which is dynamically connected, moves. When the drive plate 22 moves, it pushes the slide plate 23, which is rotatably connected to it, to slide along the spray frame 2. The slide plate 23 drives the splash box 24, which is rotatably connected at the end, to move. The guide block 25 at the bottom of the splash box 24 slides along the fixed rod 26. The positioning spring 27 on the outer wall of the fixed rod 26 deforms. Under the elastic force of the positioning spring 27, the splash box 24 vibrates, shaking off the residual paint inside. The paint shaken off by the splash box 24 flows into the collection box 9 connected to it, realizing the recycling of paint. The bottom plate 10 on the side wall of the collection box 9 provides stable support for the drive motor A11.
