Description

Technical Field

[0001] This utility model belongs to the field of lower spoiler processing technology, and relates to the inclined wedge insert cooling mechanism of the injection mold for an active lower spoiler for commercial vehicles. Background Technology

[0002] Active lower spoilers are an important component of commercial vehicles. By installing active lower spoilers, wind resistance during the driving process of commercial vehicles can be reduced. In the production and processing of active lower spoilers, they are mainly injection molded.

[0003] Traditional active lower spoiler injection molds rely on water-cooled circulating channels inside the upper and lower mold bases during injection molding. However, the lack of a cooling structure in the demolding inserts during injection can easily lead to incomplete cooling in certain areas, affecting the molding efficiency of the lower spoiler. To address this issue, we designed a wedge-shaped insert cooling mechanism for active lower spoiler injection molds used in commercial vehicles. Summary of the Invention

[0004] The purpose of this invention is to provide a cooling mechanism for the inclined wedge insert of an active lower spoiler injection mold for commercial vehicles, so as to solve the problems mentioned in the background art.

An inclined ejector rod is rotatably connected to the middle of the ejector rod connecting seat, and the inclined ejector rod passes through the lower mold base and is fixedly connected to the bottom end of the inclined wedge insert.

[0007] In the above-mentioned cooling mechanism of the inclined wedge insert of the injection mold for the active lower spoiler of commercial vehicles, both sides of the bottom end of the inclined wedge insert are provided with flow channel openings that communicate with the annular cooling flow channel, and the flow channel openings are fixedly connected with cooling water connectors.

[0009] In the above-mentioned cooling mechanism of the inclined wedge insert of the active lower spoiler injection mold for commercial vehicles, the upper mold base is fixedly provided with an upper mold core, which is adapted to the lower mold core.

Detailed Implementation

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1-6 As shown, the present invention relates to a cooling mechanism for a wedge insert in an active lower spoiler injection mold for commercial vehicles, comprising a base plate 1 and a top plate 2. Support frames are fixedly installed on both sides of the top of the base plate 1, and a lower mold base 3 is fixedly installed on the top of the two support frames. An upper mold base 4 adapted to the lower mold base 3 is fixedly installed at the bottom of the top plate 2. A lower mold core 7 is fixedly installed inside the lower mold base 3. Multiple slots 8 are equidistantly opened on the top of the lower mold core 7. Wedge inserts 10 are embedded in the multiple slots 8. An annular cooling channel 13 is opened inside the wedge inserts 10.

[0021] Specifically, by setting an annular cooling channel 13 inside the wedge insert 10, water cooling circulation can be realized, which can improve the molding efficiency of the lower spoiler injection molding of commercial vehicles and improve the processing efficiency of the lower spoiler of commercial vehicles.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the present invention relates to a cooling mechanism for an active lower spoiler injection mold for commercial vehicles. A movable ejector plate 5 is placed in the middle of the base plate 1. Multiple ejector rod connecting seats 11 are fixedly arranged at equal intervals at the top of the ejector plate 5. An inclined ejector rod 6 is rotatably connected to the middle of the ejector rod connecting seat 11. The inclined ejector rod 6 passes through the lower mold base 3 and is fixedly connected to the bottom end of the inclined wedge insert 10.

[0023] Specifically, through the cooperation of the inclined ejector rod 6 and the inclined wedge insert 10, the lower spoiler can be demolded by pushing the inclined wedge insert 10 through the inclined ejector rod 6 during demolding.

[0024] Both sides of the bottom end of the wedge insert 10 are provided with flow channel openings that communicate with the annular cooling flow channel 13, and cooling water connectors 12 are fixedly connected to the flow channel openings.

[0025] Specifically, the cooling water connector 12 facilitates the connection between the wedge insert 10 and the external water pipe.

[0026] Limiting guide posts 9 are fixedly provided at the four corners of the top of the lower mold base 3, and limiting guide holes that match the end size of the limiting guide posts 9 are opened at the four corners of the bottom of the upper mold base 4.

[0027] Specifically, the combination of the limiting guide post 9 and the limiting guide hole improves the mold closing accuracy between the lower mold base 3 and the upper mold base 4.

[0028] The upper mold base 4 is fixedly provided with an upper mold core 14, which is adapted to the lower mold core 7.

[0029] A glue injection nozzle is fixedly provided at the middle of the top of the top plate 2, and the glue injection nozzle is connected to the glue injection channel inside the upper mold base 4.

[0030] Specifically, the injection nozzle is aligned with the injection nozzle of the injection molding machine to allow the molten adhesive to flow into the mold cavity.

[0031] In specific implementation, when using the lower spoiler injection mold, the injection mold is first assembled into the injection molding machine body. Then, multiple cooling water connectors 12 are connected to an external water source through connecting water pipes. When the lower spoiler is being injected, when the upper mold base 4 and the lower mold base 3 are closed, external cold water enters from the cooling water connectors 12 into the annular cooling channel 13 inside the wedge insert 10, thereby cooling the wedge insert 10 and improving the cooling and molding efficiency of the lower spoiler.
