Description

Technical Field

[0001] This utility model relates to the field of automotive plastic parts spraying technology, specifically to an automotive plastic parts spraying fixture with quick mold change capability. Background Technology

[0002] Automotive plastic parts are core components for lightweighting and enhancing the functionality of automobiles. They are widely used in interior and exterior trim and structural parts, covering key areas such as bumpers, dashboards, door panels, and grilles. Plastic part coating is a crucial process for optimizing their performance and appearance. Through specialized coating techniques, a uniform coating is formed on the surface of the plastic substrate. This process not only gives plastic parts rich colors and gloss but also enhances surface hardness, wear resistance, and weather resistance, effectively resisting ultraviolet rays, high and low temperatures, and daily wear, thus extending the component's lifespan. Simultaneously, coating can conceal minor imperfections from the plastic molding process, resulting in a smoother and more refined surface that matches the overall vehicle design, balancing practicality and aesthetics. When spraying plastic parts, a support mold is used to support and fix the plastic parts. The support mold has plug-in pins or clamps that match the plastic parts. The plastic parts need to be selected with a support mold that matches their model. Therefore, when processing different models of plastic parts, the corresponding support mold needs to be replaced. The support mold is usually fixed to the rotating frame with screws. When disassembling and assembling, tools are needed to unscrew the screws one by one and then reassemble them in sequence, which results in low efficiency of mold replacement and affects the spraying efficiency. The existing technology has not solved this problem. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: A quick-change automotive plastic parts spraying fixture includes a mold body, the mold body includes a support frame 10, the top of the support frame 10 is equipped with an insertion post 11, the bottom of the support frame 10 is slidably installed in an installation groove 2, an alignment block 12 is fixedly installed at the bottom of the support frame 10, an alignment groove 13 is opened in the installation groove 2, and the alignment block 12 is inserted into the alignment groove 13.

[0017] The main function of the mold body is to provide stable support and positioning for the plastic parts. The core of the mold body consists of a support frame 10 and a top insertion post 11. The bottom of the support frame 10 is installed in the mounting groove 2 of the fixed base 1 by sliding. The top insertion post 11 can accurately match the structure of the plastic parts to be sprayed, thereby providing stable support and positioning for the plastic parts and ensuring that the plastic parts will not shift during the spraying process. The alignment block 12 at the bottom of the support frame 10 cooperates with the alignment groove 13 in the mounting groove 2, which can quickly and accurately align the mold body with the fixed base 1, while preventing the support frame 10 from sliding horizontally in the mounting groove 2 after installation, thus laying the foundation for subsequent rapid mold change and efficient spraying.

[0018] The system also includes a fixing component, a fixing base 1, with two sets of mounting grooves 2 on the top of the fixing base 1, and a telescopic groove 3 on one side of the mounting groove 2. A retaining plate 4 is slidably installed in the telescopic groove 3. Two sets of guide posts 5 are fixedly installed on one side of the retaining plate 4. The guide posts 5 are slidably engaged with the fixing base 1. A spring 6 is slidably sleeved on the surface of the guide post 5. One end of the spring 6 abuts against the retaining plate 4, and the other end of the spring 6 abuts against the inner wall of the telescopic groove 3. An arc-shaped groove 14 is opened on the other side of the retaining plate 4. The arc-shaped groove 14 abuts against the bottom sides of the support frame 10. Two sets of handles 15 are provided on both sides of the fixing base 1. The handles 15 are fixedly connected to the guide posts 5. The fixing base 1 is fixedly installed in the middle of the top of the turntable 16. A rotating ring 17 is fixedly installed around the turntable 16. The turntable 16 is rotatably installed on the top of the support column 18.

[0019] The main function of the fixing component is to achieve stable installation and quick disassembly of the mold body. The fixing component uses the fixing base 1 as the installation base and works in conjunction with components such as the mounting groove 2, telescopic groove 3, clamping plate 4, guide post 5, and spring 6. The elastic force of the spring 6 pushes the clamping plate 4 to slide in the telescopic groove 3, so that the clamping plate 4 tightly abuts against the bottom sides of the support frame 10 through the arc groove 14, thereby firmly fixing the mold body in the mounting groove 2. This prevents the spraying accuracy from being affected by the mold shaking during spraying. The arc groove 14 also limits the bottom of the support frame 10 to prevent the mold body from sliding up and down after installation. The guide post 5 ensures that the clamping plate 4 slides smoothly, and the handles 15 on both sides provide a force point for manual operation, making it easy to control the movement of the clamping plate 4, thus balancing the reliability of the fixing and the convenience of operation.

[0020] It also includes a linkage assembly, which includes two sets of driving racks 7. The two sets of driving racks 7 are fixedly connected to the bottom sides of one set of abutment plates 4. The two sets of driving racks 7 respectively mesh with the outer sides of two sets of gears 8. The inner sides of the two sets of gears 8 mesh with the sides of driven racks 9. The driven racks 9 are fixedly connected to another set of abutment plates 4. The gears 8 are rotatably installed in the transmission groove opened at the bottom of the fixed base 1. The transmission groove is provided with guide grooves that slide with the driving racks 7 and the driven racks 9.

[0021] The main function of setting up the linkage component is to further improve the disassembly and assembly efficiency, thereby enabling rapid replacement of the mold body. The linkage component transmits power through the meshing of the active rack 7, gear 8, and driven rack 9. When the handle 15 on one side is pulled to move the corresponding clamping plate 4, the active rack 7 at the bottom of the clamping plate 4 drives the gear 8 to rotate, and the gear 8 in turn drives the driven rack 9 to move in the opposite direction, ultimately achieving simultaneous back-to-back movement of the two sets of clamping plates 4, quickly releasing the fixation of the support frame 10. By setting up the linkage component, it is possible to eliminate the need to disassemble the fixing structure one by one, greatly simplifying the mold body disassembly process, shortening the mold change time, and effectively improving the overall efficiency of the spraying operation.

[0022] In practical use, after installing the device in the designated position, first pull the guide column 5 outward using the handle 15, causing one set of clamping plates 4 to compress the spring 6 and move into the telescopic groove 3. At the same time, the driving rack 7 (or driven rack 9) at the bottom of the clamping plate 4 drives the gear 8 to rotate. The gear 8, in conjunction with the driven rack 9 (or driving rack 7), drives the other set of clamping plates 4 to move synchronously in opposite directions, so that the two sets of mounting grooves 2 are in an open state. Then, align the bottom of the mold body (support 10) of the plastic part to be sprayed with the mounting groove 2, and insert the alignment block 12 into the alignment groove. After the groove 13 completes precise positioning, the spring 6 elastically resets and pushes the two sets of clamping plates 4 to move towards each other. The arc groove 14 tightly contacts the bottom sides of the support frame 10 to achieve stable fixation. Then, the plastic parts are inserted into the corresponding plug-in posts 11 at the top of the support frame 10 to complete the clamping. During the spraying process, the rotating ring 17 can drive the turntable 16 to rotate to ensure that the plastic parts are sprayed evenly. When the mold needs to be changed, pull the handle 15 again to release the two sets of clamping plates 4 simultaneously. The old mold body can be directly removed and the new mold body can be installed. After the quick mold change is completed, the spraying operation can continue.

[0023] 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.
