Description

Technical Field

[0001] This utility model belongs to the technical field of paint masking fixtures, specifically relating to a top-mounted paint masking fixture. Background Technology

[0002] Traditional paint masking fixtures are typically customized based on the number of products, leading to resource waste. To address this, the paint masking fixture provided in authorization notice CN219291728U features a detachable masking component. After painting and before baking, the masking component can be removed and reused for the next coat, reducing the required number of masking components. However, the masking component in the aforementioned fixture is magnetically attached to the support, requiring up-and-down movement before and after painting, which is cumbersome. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a top-mounted paint masking fixture.

[0004] To achieve the above objectives, this utility model discloses an ejector-type paint masking fixture, including a worktable, a shielding component, and an ejector assembly. The workbench is provided with a first clearance hole that penetrates its top and bottom surfaces; The shielding component is fixedly connected to the workbench and is used to support and shield the non-painted area of ​​the product to be painted. The shielding component is provided with a second clearance hole that penetrates its top and bottom surfaces. The second clearance hole and the first clearance hole are arranged opposite to each other. The ejection assembly includes an ejection base, an ejection rod, and an ejection support plate. The ejection base is located below the worktable. The bottom end of the ejection rod is fixedly connected to the ejection base. The top end of the ejection rod passes through the first clearance hole and the second clearance hole in sequence and extends upward through the shielding member. The top end of the ejection rod is fixedly connected to the ejection support plate. The top view projection of the ejection support plate is located inside the shielding member and is used to abut against the inner wall of the product to be painted.

[0005] Furthermore, there are multiple ejector rods, and multiple sets of the first and second clearance holes.

[0006] Furthermore, the plurality of ejector rods are evenly arranged.

[0007] Furthermore, the shielding member is provided with a guide block, and the ejector plate is provided with a guide hole that cooperates with the guide block.

[0008] Furthermore, the shielding component is detachably connected to the worktable, and the ejector rod and ejector plate are detachably connected.

[0009] Furthermore, the ejector base is provided with a limiting member, which is fixedly connected to the top surface of the ejector base and engages with the bottom surface of the worktable or the shielding member for limiting.

[0010] Furthermore, the ejector base is provided with a threaded hole, and the limiting member is a bolt threaded into the threaded hole.

[0011] Furthermore, the ejector base has a through hole at the middle position, penetrating its top and bottom surfaces.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Under normal conditions, the ejector assembly falls under its own weight, with the ejector plate located inside the shielding component. During painting, the product to be painted is placed on the shielding component, which supports and shields the non-painted areas of the product, allowing for painting. After painting, the ejector base is lifted, and the ejector base, via the ejector rod, lifts the ejector plate, which then ejects the product from the shielding component. Since the top-view projection of the ejector plate is located inside the shielding component, meaning that after the ejector plate contacts the inner wall of the product, the inner wall portion of the product is outside the ejector plate, once the product is ejected from the shielding component, the operator can hold the product by its inner wall (outside the ejector plate) and take it to the baking equipment for baking; there is no need to remove the ejector plate. In this technology, the product to be painted is placed on a shielding component, and after painting, it is ejected by an ejector plate. The ejector plate is located inside the product to be painted, and there is still space on the inner side wall of the product outside the ejector plate for the operator to hold. Therefore, as in the prior art, there is no need for the carrier / shielding component to enter the oven with the product for baking. This reduces the number of carrier / shielding components required and lowers costs.

[0013] After the staff picks up the product to be painted, they remove the support from the ejector base. The ejector component falls automatically under its own weight, eliminating the need to manually pull it down, making the operation convenient. Attached Figure Description

Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] A top-mounted paint masking fixture, see [link / reference] Figures 1-5 The system includes a worktable 100, a shielding component 200, and an ejector assembly 300. The shielding component 200 is fixedly connected to the worktable 100 and is used to support and shield the non-painted area of ​​the product 400 to be painted. The ejector assembly 300 is used to lift the product 400 to be painted on the shielding component 200 and place the painted product 400 into the oven for baking.

[0017] In this embodiment, the workbench 100 is provided with a first clearance hole 110 penetrating its top and bottom surfaces, and the shield 200 is provided with a second clearance hole 210 penetrating its top and bottom surfaces. The second clearance hole 210 and the first clearance hole 110 are arranged opposite to each other. The ejector assembly 300 includes an ejector base 310, an ejector rod 320, and an ejector plate 330. The ejector base 310 is located below the worktable 100. The bottom end of the ejector rod 320 is fixedly connected to the ejector base 310. The top end of the ejector rod 320 passes through the first clearance hole 110 and the second clearance hole 210 in sequence and extends upward to the shielding member 200. The top end of the ejector rod 320 is fixedly connected to the ejector plate 330. The top view projection of the ejector plate 330 is located inside the shielding member 200, thereby dividing the inner wall of the product 400 to be painted into two parts. One part is located inside the ejector plate 330, and the other part is located outside the ejector plate 330. The outline of the ejector plate 330 is adapted to the outline of the inner wall it contacts. It contacts the inner wall of the product 400 to be painted, thereby lifting the painted product 400 when the ejector base 310 and the ejector rod 320 are lifted upward.

[0018] Under normal conditions, the ejector assembly 300 falls under its own weight, and the ejector plate 330 is located inside the shielding member 200. During painting, the product 400 to be painted is placed on the shielding member 200, which supports and shields the non-painted areas of the product 400, allowing for painting. After painting, the ejector base 310 is lifted, and the ejector base 310, via the ejector rod 320, lifts the ejector plate 330, which then ejects the product 400 from the shielding member 200. Since the top-view projection of the ejector plate 330 is located inside the shielding member 200, in other words, after the ejector plate 330 contacts the inner wall of the product 400 to be painted, the inner wall portion of the product 400 to be painted is located outside the ejector plate 330. When the product 400 to be painted is ejected from the shielding member 200, the operator can hold the inner wall portion of the product 400 outside the ejector plate 330 (e.g., the inner wall portion of the product 400 to be painted outside the ejector plate 330). Figure 5 As shown, the inner wall of the product 400 to be painted, located outside the ejector plate 330, has sufficient space and structure for the operator to hold. The product 400 can be placed in the baking equipment for baking without removing the ejector plate 330. In this embodiment, the product 400 is placed on the shielding member 200. After painting, it is ejected by the ejector plate 330, which is located inside the product 400. The inner wall of the product 400 still has space outside the ejector plate 330 for the operator to hold. Therefore, unlike existing technologies, there is no need for the support member / shielding member 200 to enter the oven with the product for baking. This reduces the number of support members / shielding members 200 required and lowers costs. After the operator picks up the product 400, the support for the ejector base 310 is removed, and the ejector assembly 300 automatically falls under its own weight, eliminating the need to manually pull down the ejector assembly 300, making operation convenient.

[0019] In this embodiment, the second clearance hole 210 of the shielding member 200 acts as a guide hole and cooperates with the ejector rod 320. This can improve the stability of the ejector rod 320 moving up and down, and ensure that the ejector plate 330 can move vertically up and down, thereby smoothly ejecting the product 400 to be painted.

[0020] There are multiple ejector rods 320, specifically four in this embodiment, with four sets of first clearance holes 110 and second clearance holes 210 corresponding to each other. The four ejector rods 320 connect the ejector plate 330 and the ejector base plate, which not only ensures a stable connection but also further improves the stability of the ejector plate 330's vertical movement.

[0021] The four ejector rods 320 are evenly distributed. Specifically, the ejector base 310 is a rectangular block, and the four ejector rods 320 are respectively located at the four corners of the rectangular block.

[0022] In this embodiment, the shielding member 200 is provided with a guide block 220, and the ejector plate 330 is provided with a guide hole 331 that cooperates with the guide block 220, which further improves the stability of the shielding member 200 moving up and down.

[0023] Different models and specifications of products 400 to be painted have different inner wall contours. To improve the versatility of the fixture, the shielding component 200 is detachably connected to the worktable 100, and the ejector rod 320 and ejector plate 330 are detachably connected. The detachable connection methods include, but are not limited to, threaded connections and snap-fit ​​connections. Thus, when changing the product to be painted, only the corresponding shielding component 200 and ejector plate 330 need to be replaced.

[0024] In this embodiment, a limiting member 311 is provided on the ejector base 310. The limiting member 311 is fixedly connected to the top surface of the ejector base 310, and the limiting member 311 is matched with the bottom surface of the worktable 100 or the shielding member 200. When the ejector base 310 is lifted, the top surface of the limiting member 311 is restricted by the worktable 100 or the shielding member 200. At this time, the worker can intuitively see that the painted product 400 to be baked has moved to a suitable height and can be removed.

[0025] In this embodiment, the first clearance hole 110 that cooperates with the four ejector rods 320 is a through hole located in the middle of the ejector base 310. The position of this hole is opposite to the limiting member 311. Therefore, the top surface of the limiting member 311 is limited and cooperates with the blocking member 200.

[0026] The ejector base 310 has a threaded hole, and the limiting member 311 is a bolt threaded into the threaded hole. Using a bolt as the limiting member 311 results in a simple structure, and the height can be adjusted by the operator to suit the actual working conditions.

[0027] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
