Attached Figure Description
[0015] The accompanying drawings are not intended to be drawn to scale. In the drawings, each identical or nearly identical component shown in the various figures may be denoted by the same reference numeral. For clarity, not every component is labeled in each figure. Embodiments of various aspects of the present invention will now be described by way of example and with reference to the accompanying drawings, wherein:
[0016] Figure 1 This is a schematic diagram of the part of the sprayed product shown in this utility model placed in the fixture and covered;
[0017] Figure 2 This is a schematic diagram of the structure of the masking fixture for spray-coated products shown in this utility model;
[0018] Figure 3This is a schematic diagram of the structure of the covering component shown in this utility model; Detailed Implementation
[0019] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.
[0020] Currently, the method of using mold-making to mask products involves adding detachable injection-molded parts to the areas that need to be masked, based on the original parts. After the painting is completed, the injection-molded parts are removed. This method firstly increases the cost of mold making, secondly increases the disassembly time, and thirdly increases the probability of scratching the painted surface during the disassembly process, thus reducing the product yield.
[0021] Therefore, the present invention proposes a masking fixture suitable for sprayed products, which aims to cover the target area of the injection molded part by adding a masking component that can be repositioned on the fixture, thereby achieving the purpose of partial spraying.
[0022] Combination Figure 1 and Figure 2 As shown, the spray masking fixture includes a base plate 10, a plurality of support structures 20 and at least one masking component 30. Each support structure 20 is installed at a predetermined position on the base plate 10, and the masking component 30 is connected to any one or more of the plurality of support structures 20.
[0023] It should be understood that for each product 100 to be sprayed, its structure is different and the area to be covered is different. Therefore, the support structure 20 needs to be set at a predetermined position on the base plate 10, which is determined according to the shape of the product 100 to be sprayed. The setting position and number of the covering parts 30 are determined according to the covering area of the product 100 to be sprayed.
[0024] The covering component 30 is hinged to the support structure 20, and the covering component 30 can rotate relative to the support structure 20, so that the covering component 30 is in a first position or a second position.
[0025] In an optional embodiment, the covering member 30 is configured to rotate 180° from the first position and then move to the second position.
[0026] Thus, when the masking component 30 is in the first position, the product to be coated 100 can be placed on the support structure 20 and supported.
[0027] Specifically, at this time, the product to be sprayed 100 can be placed on top of all the support structures 20 from above, and will not scratch any of the support structures 20 and the covering parts 30.
[0028] After the product 100 to be sprayed is placed, the masking component 30 rotates from the first position to the second position, and the masking component 30 can cover the masking area of the product 100 to be sprayed.
[0029] In this way, the product 100 to be sprayed forms an exposed area and a masked area on one side of the spraying equipment. The exposed area is the area to be sprayed. When the spraying equipment sprays the product 100, the exposed area is sprayed to form a paint layer, while the masked area is not sprayed. By rotating the masking component 30 from the second position to the first position, the sprayed product can be taken out.
[0030] Since the product needs to be placed stably during the spraying process, and the product is basically not subjected to forces other than gravity, only longitudinal support is required. In an optional embodiment, the support structure 20 is constructed as a columnar support structure.
[0031] Furthermore, the support structure 20 is divided into two types: the first type is not connected to the covering component 30, and the second type is connected to the covering component 30.
[0032] Considering the connection with the covering component 30, its upper end should be easy to set with a hinge structure. The first type of support structure 20 is constructed as a cylindrical structure 23, and the second type of support structure 20 is constructed as a rectangular column structure.
[0033] like Figure 2 As shown, the second type of covering component 30 includes a transverse support column 21 and a longitudinal support column 22. The transverse support column 21 is arranged transversely, and the longitudinal support column 22 is arranged longitudinally.
[0034] Specifically, the top of the transverse support column 21 is connected to the cover component 30, and the axial direction of the hinge axis between the cover component 30 and the transverse support column 21 is transverse. The top of the longitudinal support column 22 is connected to the cover component 30, and the axial direction of the hinge axis between the cover component 30 and the longitudinal support column 22 is longitudinal.
[0035] Thus, the horizontal support column 21 can be set on the upper and lower sides of the product. When the covering component 30 rotates around the horizontal axis, the covering component 30 can be flipped up and down. The vertical support column 22 is set on the left and right sides of the product. When the covering component 30 rotates around the vertical axis, the covering component 30 can be flipped left and right.
[0036] More specifically, the bottom of the support structure 20 is provided with a connecting column 221, the base plate 10 includes a frame 11 and multiple support rods 12 disposed in the frame 11, the surface of the support rods 12 is provided with a socket 13, and the connecting column 221 is inserted into the socket 13.
[0037] Thus, the plug-in method allows for convenient disassembly and installation of the support structure 20 as needed, adapting to different products with high flexibility and good compatibility.
[0038] Furthermore, each support rod 12 is provided with multiple insertion holes 13, so that the support structure 20 can be connected to different positions of the support rod 12 according to the shape of the product to adapt to the outer contour of the product.
[0039] In other embodiments, the support rod 12 can be moved and adjusted to different positions within the frame 11. For example, the support rod 12 can move along the inner wall of the frame 11, the inner wall of the frame 11 is provided with screw holes, and the support rod 12 and the frame 11 are connected by screws.
[0040] Combination Figure 3 As shown, the covering component 30 includes a covering part 31 and a connecting part 32. The top of the transverse support column 21 and the longitudinal support column 22 are provided with a connecting shaft 222, and the connecting part 32 is connected to the connecting shaft 222.
[0041] It should be understood that the shape of the covering part 31 is set to be the same as the covering area of the product in order to achieve complete coverage of the covering area.
[0042] Furthermore, the covering part 31 and the connecting part 32 are integrally formed stainless steel structures. This ensures that the fixture will not deform under high temperatures during the paint drying process after spraying.
[0043] In conjunction with the above embodiments, the masking fixture used in this utility model has a hinged connection between the support structure and the masking component. The masking component can be flipped over as needed to cover the area of the product that needs to be covered. During spraying, the paint will not cover the masking area. After spraying is completed, the masking component is flipped over and the product is removed. This fixture has low manufacturing cost, is easy to maintain, and can quickly cover the product during the spraying process without causing scratches, resulting in good spraying quality and good economic benefits.
[0044] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
