Description
Technical Field
[0001] The utility model relates to the technical field of spraying fixtures, and more specifically, to a spraying fixture that can be used for color paint sealing. Background Art
[0002] In the current field of color paint spraying for automotive trim parts, usually several processes are required for the production and processing of a painted workpiece. If the color paint spraying surface of the workpiece is not the A surface, then during the color paint spraying process, the A surface of the workpiece will be left with color paint mist. Waiting for the next process to be carried out will result in unnecessary defects due to the paint mist problem, such as virtual spraying caused by incomplete wiping and serious waste of working hours caused by wiping. This reduces the product qualification rate and greatly increases the time cost. For example, headlight masks, internal reflectors of vehicle lights, ashtray covers, exterior front nameplates, etc. First, Pu color paint needs to be sprayed, and a spraying fixture is required during spraying. Most of the spraying fixtures for these common painted workpieces are in a bare hanging manner. After spraying, there will be residual paint mist on the front of the workpiece. In the next process, manual wiping of the paint mist is required, but the wiping effect is not ideal and it is very easy to produce defective products. Summary of the Utility Model

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0034] Refer to Figures 1 to 10 , this embodiment provides a spraying fixture available for color paint sealing, including: a housing 100, a cover plate 200 and a sealing component 300.
[0035] The housing 100 is configured as a shallow groove structure made of stainless steel. On the inner side surface of the housing 100, there are profiling blocks 110 for fixing the workpiece 400. The number of the profiling blocks 110 can be set according to actual requirements. In this embodiment, there are three profiling blocks 110. At the same time, in order to be able to adapt to different workpieces 400 and facilitate cleaning, in this embodiment, the profiling blocks 110 are detachably connected to the housing 100 through connecting parts such as bolts.
[0036] The cover plate 200 covers the side of the housing 100 where the profiling blocks 110 are provided. The cover plate 200 is movably connected to the housing 100 through a hinge 230. The cover plate 200 can be opened and closed relative to the housing 100 and can be locked by a lock 210 in the closed state; a spraying port 220 is provided on the cover plate 200 at a position corresponding to the profiling blocks 110.
[0037] The lock 210 includes a lock part 211 and a lock pin 212. The lock part 211 is configured as a plate member substantially in a Z shape. The lock part 211 is bent to have a connecting part 2111, a locking part 2112, and an operating part 2113. One end of the connecting part 2111 is rotatably connected to the cover plate 200. One end of the locking part 2112 is vertically connected to the other end of the connecting part 2111. The middle part of the locking part 2112 is lower than the two end parts. The operating part 2113 is connected to the other end of the locking part 2112; the lock pin 212 is connected to the housing 100. When the operator rotates the lock part 211 in one direction through the operating part 2113, the locking part 2112 can be engaged with the lock pin 212. Since the middle part of the locking part 2112 is lower than the two end parts, without external force, the locking part 2112 will not disengage from the lock pin 212, so as to realize the locking between the cover plate 200 and the housing 100; when unlocking is required, rotate the lock part 211 in the opposite direction through the operating part 2113 to disengage the locking part 2112 from the lock pin 212, and the unlocking can be completed.
[0038] The sealing assembly 300 includes a sealing strip 310 and a fixing part 320. The fixing part 320 is made of POM plastic material and is configured as an annular member, which is connected to the inner side of the cover plate 200. The annular space of the fixing part 320 corresponds to the spraying port 220 on the cover plate 200; the sealing strip 310 is made of high-temperature resistant and silicone-free material and is installed in the annular space of the fixing part 320. When the cover plate 200 and the housing 100 are relatively closed, the sealing strip 310 surrounding the spraying port 220 forms a seal with the surface of the workpiece 400.
[0039] In this embodiment, the fixing member 320 is detachably connected to the cover plate 200 , and different fixing members 320 can be replaced and different sealing strips 310 can be installed to adapt to the sealing of different workpieces 400 .
[0040] See also Figures 8 to 10 , a method for using a spray hanger for paint sealing provided in this embodiment:
[0041] First, the workpiece 400 is fixed inside the shell 100 by the contour block 110, the cover plate 200 is closed, and the cover plate 200 and the shell 100 are locked by the lock 210; then spraying is started, and the sealing strip 310 forms a seal between the cover plate 200 and the workpiece 400. During the spraying process, the paint mist cannot spread to the non-painted surface of the workpiece 400, thereby protecting the non-painted surface of the workpiece and preventing paint mist pollution.
