Description

Technical Field

[0001] This utility model relates to the field of aluminum plating technology for automotive lighting parts, specifically to an aluminum plating fixture with a liftable bottom mold. Background Technology

[0002] In automotive lighting manufacturing, key components such as trim rings and reflectors are usually treated with aluminum plating. This not only improves the product's appearance and texture, but also significantly enhances optical reflectivity, improves electrical conductivity, and optimizes heat dissipation. However, some parts have complex structures, which requires the use of aluminum plating fixtures to shield the areas that do not need to be aluminum plated.

[0003] Existing aluminum plating fixtures, such as the aluminum plating mask fixture disclosed in CN214244587U, use hinged first and second masking plates to clamp the workpiece and mask areas that do not require aluminum plating. In use, the workpiece is placed in the first cavity of the first masking plate, then the second masking plate is closed and the two plates are fixed by a locking assembly. Aluminum plating is then performed on the corresponding areas of the workpiece. After plating, to remove the workpiece, the locking assembly is released, and then the second masking plate is flipped open to allow the workpiece to be removed. While these existing aluminum plating fixtures are suitable for some simple workpieces, for complex structures, such as those with an annular groove, when the four sides of the groove need to be masked, sometimes the fixture cover needs to be inserted into the groove. This can cause the fixture cover to rub against the workpiece during opening after plating, resulting in scratches. Utility Model Content

[0004] To address the problem that existing aluminum plating fixtures may scratch workpieces during the opening process, this utility model provides an aluminum plating fixture with a liftable bottom mold, which can reduce or even avoid the possibility of the fixture cover scratching the workpiece after aluminum plating is completed.

[0005] The technical solution is as follows: a lifting-type aluminum plating fixture, comprising a base, a bottom mold, a top cover, and a locking mechanism. The bottom mold is mounted on the base and has a placement cavity for placing workpieces. The top cover is located above the bottom mold and includes a shielding part for covering areas of the workpiece that do not require aluminum plating and an open slot for exposing the aluminum-plated areas of the workpiece. The locking mechanism prevents the top cover from being opened when it is closed. The fixture is characterized in that the top cover is rotatably mounted on the aluminum plating device, and the base is connected to the bottom mold via a lifting mechanism.

[0006] Furthermore, the locking mechanism includes a fixed base, a locking plate, and a clamping bolt. The fixed base is fixed to the aluminizing device and has an upward-opening locking groove. When the tooling cover is in the closed state, its forward-extending extension rod is located in the locking groove. The clamping bolt passes through the locking plate and the fixed base in a vertical direction. The locking plate can rotate around the clamping bolt, and the locking plate prevents the tooling cover from being opened by rotating above the extension rod.

[0007] Furthermore, the locking mechanism also includes a compression spring, which is provided between the compression bolt and the fixed seat. The compression spring is used to apply downward pressure to the head of the compression bolt, and the head of the compression bolt presses the locking piece against the fixed seat.

[0008] Furthermore, the lifting mechanism includes a supporting square tube, a lifting rod, an upper connecting rod, a lower connecting rod, and a pull rod. The lifting rod is capable of moving up and down relative to the supporting square tube. The lifting rod and the supporting square tube are respectively used to connect the tooling bottom mold and the base. The lower end of the lower connecting rod is rotatably mounted on the base. The upper end of the lower connecting rod is rotatably connected to the lower end of the upper connecting rod. The upper end of the upper connecting rod is rotatably mounted on the lower end of the tooling bottom mold. The pull rod is used to apply a force in the front-back direction to the lower end of the upper connecting rod or the upper end of the lower connecting rod.

[0009] Beneficial effects: Compared with existing aluminum plating fixtures, the fixture bottom mold of this solution is connected to the lifting mechanism. After aluminum plating is completed, the lifting mechanism can be controlled to first drive the fixture bottom mold to descend, thereby driving the workpiece to descend together. At this time, opening the fixture top cover will not interfere with the workpiece, thus ensuring the processing quality. Attached Figure Description

[0011] Figure 2 This is a side view of the present invention;

[0012] Figure 3 This is a schematic diagram of the locking mechanism. Detailed Implementation

[0013] like Figure 1 , Figure 2The figure shows a lifting-type aluminum plating fixture, which includes a base 1, a base plate 5, a fixture bottom mold 6, a fixture top cover 7, an upper frame 9, and a locking mechanism 10. The fixture bottom mold 6 is provided with the base plate 5 below it. The fixture bottom mold 6 and the base plate 5 are mounted on the base 1 by means of the lifting mechanism. The fixture bottom mold 6 is provided with a placement cavity for placing workpieces. The fixture top cover 7 is located above the fixture bottom mold 6. The fixture top cover 7 includes a shielding part for shielding the parts of the workpiece that do not need to be aluminum-plated, an open slot for exposing the aluminum-plated parts of the workpiece, and an upper frame 9 for gripping. The fixture top cover 7 is rotatably mounted on the platform of the aluminum plating device (not shown in the figure) by means of a flip hinge 8. The locking mechanism 10 is used to prevent the fixture top cover 7 from being opened when it is in the closed state.

[0014] Specifically, in combination Figure 3 The locking mechanism 10 includes a fixed base 101, a locking piece 102, and a clamping bolt 103. The fixed base 101 is fixed on the platform of the aluminum plating device (not shown in the figure). The fixed base 101 is provided with an upward-opening locking groove 104. When the tooling cover 7 is in the closed state, its forward-extending extension rod 701 is located in the locking groove 104. The clamping bolt 103 passes through the locking piece 102 and the fixed base 101 in the vertical direction. The locking piece 102 can rotate around the clamping bolt 103. The locking piece 102 prevents the tooling cover 7 from being opened by rotating above the extension rod 701. Since the locking piece 102 rotates around the vertical axis and the extension rod 701 rotates around the horizontal axis, the locking piece 102 can effectively prevent the extension rod 701 from rotating, thereby preventing the tooling cover 7 from opening. To prevent the locking piece 102 from being easily pried open, the locking mechanism 10 also includes a compression spring 104. A compression spring 104 is provided between the compression bolt 103 and the fixing seat 101. The compression spring 104 is used to apply downward pressure to the head of the compression bolt 103. The head of the compression bolt 103 presses the locking piece 102 against the fixing seat 101, so a certain force needs to be applied to pry the locking piece 102 so that it rotates around the compression bolt 103.

[0015] Although the lifting mechanism can directly use devices such as cylinders, it often requires a series of accessories such as cylinders and pipelines, and also consumes energy for driving. For ease of use, the lifting mechanism includes a supporting square tube 2, a linear bearing 3, a lifting rod 4, an upper connecting rod 12, a lower connecting rod 13, and a pull rod 15. The linear bearing 3 is installed on the supporting square tube 2 to allow the lifting rod 4 to move up and down relative to the supporting square tube 2. The supporting square tube 2 and the lifting rod 4 are used to connect the base 1 and the base plate 5 under the tooling bottom mold 6. The lower end of the lower connecting rod 13 is rotatably installed on the base 1 through the lower corner piece 14. The upper end of the lower connecting rod 13 is rotatably connected to the lower end of the upper connecting rod 15. The upper end of the upper connecting rod 15 is rotatably installed on the base plate 5 at the lower end of the tooling bottom mold 6 through the upper corner piece 11. The pull rod 15 is used to apply force to the lower end of the upper connecting rod 12 or the upper end of the lower connecting rod 13 in the front-back direction.

[0016] When used, by Figure 1 Apply a backward force to the pull rod 15 in the direction of the direction. The lower end of the upper connecting rod 12 and the upper end of the lower connecting rod 13 are deflected backward by the force, thereby reducing the distance between the base 1 and the tooling bottom mold 6. The support square tube 2 and the lifting rod 4 cooperate to play a guiding role. Then open the locking mechanism 10, and then flip the combination of the upper frame 9 and the tooling top cover 7 around the flip hinge 8. Then put the aluminum-plated workpiece into the tooling bottom mold 6. Finally, perform the above steps in the reverse order to complete the installation of the aluminum-plated parts. The method and steps for taking out the parts are the same as those for installation.

[0017] This lifting structure avoids interference with the workpiece during the opening and closing of special workpieces, preventing them from opening or closing, or scratching the workpiece due to friction. This fixture can be made by 3D printing 316L stainless steel. The fixture design and manufacturing cycle is short, and the fixture can be made without relying on additional parts, ensuring that the fixture and parts are delivered simultaneously.

[0018] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
