Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically relating to an integrated molding mold for automotive air vent guide vanes. Background Technology

[0002] In the automotive parts manufacturing industry, air vent deflectors are key components for adjusting the direction of airflow. Their structure typically consists of two parts: the deflector body and the air vent. The deflectors are often angled to meet multi-angle airflow requirements. Currently, the industry primarily uses injection molding to produce air vent deflectors. However, existing injection molds have numerous technical limitations in practical applications, making it difficult to meet the demands for efficient and stable production.

[0003] Traditional molds often employ an integrated core design with fixed and moving molds. Due to the inclined blade structure, the core and blades fit closely after injection molding, and the lack of a specific demolding guide structure makes it easy for the blades to get stuck with the core during demolding. Furthermore, in existing molds, the forming cores of the air vents and blades are often connected and fixed structures. The fixed mold lacks appropriate clearance components to accommodate the inclined blades. When the moving mold separates the core, parts of the fixed mold can easily squeeze or obstruct the molded inclined blades, increasing demolding difficulty and potentially causing blade deformation, breakage, and other defects, thus reducing product yield.

[0004] In addition, the demolding parts of existing molds are mostly designed for a single part such as the air vent or blade, which cannot achieve synchronous and smooth demolding of the air vent and blade. The mold state needs to be adjusted multiple times during the demolding process, which prolongs the production cycle and reduces production efficiency.

[0005] Therefore, how to design an integrated molding die for automotive air vent guide vanes has become a pressing technical problem in the industry. Utility Model Content

[0006] This utility model addresses the shortcomings of existing technologies by providing an integrated molding mold for automotive air vent guide vanes. The specific technical solution is as follows:

[0007] An integrated molding die for an automotive air vent guide vane includes a fixed die and a movable die. The movable die has a sub-die in its middle that can move along the vane. The surface of the sub-die has a vane core for injection molding of the vane. The upper surface of the fixed die has a retaining strip integrally formed. The connection between the fixed die, the movable die, the sub-die, and the retaining strip has an air vent core for injection molding of the air vent, and the air vent core is connected to the vane core. The surface of the sub-die near the fixed die has a connecting groove that is perpendicular to the vane core. The end of the movable die away from the fixed die has a demolding member, and one end of the demolding member is located inside the air vent core.

[0008] Preferably, the demolding component includes a demolding cavity formed on the upper surface of the moving mold, a cover plate for protecting the demolding cavity is installed on the upper surface of the moving mold, and the demolding cavity is located outside the air guide mold core. A demolding rod is movably installed inside the demolding cavity, one end of the demolding rod extends into the air guide mold core, and the other end of the demolding rod extends outside the cover plate. A baffle is welded to the surface of the demolding rod inside the demolding cavity, and a spring is fixed to the lower surface of the baffle.

[0009] Preferably, there are two symmetrically arranged demolding components, and the demolding rods installed in each demolding cavity are distributed in a linear array.

[0010] Preferably, four linkage cylinders are installed on the upper surface of the cover plate, and the inlet and outlet ends of the four linkage cylinders are connected by two inlet and outlet pipes respectively. The telescopic end of the linkage cylinder is equipped with a linkage rod, and the linkage rod is fixed to the upper surface of the sub-mold.

[0011] Preferably, the linkage cylinder is parallel to the blade mold core.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Solving demolding obstacles and improving product qualification rate: This utility model uses an integrally formed retaining strip on the upper surface of the fixed mold. The retaining strip, in conjunction with the fixed mold and the sub-mold, creates a clearance space suitable for the inclined blades, effectively avoiding the squeezing and obstruction of the inclined blades by the fixed mold structure in traditional molds. Simultaneously, the sub-mold's design, which allows movement along the blade's tilt angle, enables adaptive movement after injection molding, further reducing the risk of jamming between the blade and the mold core. This significantly reduces the probability of blade deformation and breakage during demolding, greatly improving the product qualification rate.

[0014] 2. Achieve efficient synchronous demolding and shorten production cycle: The fixed mold, sub-mold, and retaining strip adopt a split structure design. Combined with a demolding component located at the end of the moving mold furthest from the fixed mold, when the moving mold moves upward for demolding, the demolding component directly acts on the air guide inside the air guide mold core. Simultaneously, the movement of the sub-mold causes the blades to detach synchronously from the mold core, achieving smooth and synchronous demolding of the air guide and blades. Compared to traditional demolding methods that require multiple adjustments, this solution significantly simplifies the demolding process, shortens the demolding time per production run, thereby improving overall production efficiency and reducing production costs.

[0015] 3. Optimized molding structure to ensure integrated molding quality: The design connecting the air vent core and the blade core ensures that the air vent and blades can be integrally molded during injection molding, avoiding dimensional deviations caused by assembly after traditional separate molding. Simultaneously, the connecting groove on the sub-mold surface is perpendicular to the blade core, providing a stable channel for the flow of injection molding material and enhancing the structural strength of the molded blades. This ensures the overall performance and structural stability of the automotive air vent air guide blades, meeting the high-precision, high-quality production requirements of automotive parts.

[0016] 4. The rational structural design enhances the practicality and flexibility of the mold: The sub-mold's design, which allows it to move along the blades, enables the mold to adapt to the production needs of blades with different tilt angles. Simply adjusting the sub-mold's movement trajectory allows for the molding of guide vanes of different specifications, improving the mold's versatility and flexibility. Furthermore, the integrated molding structure of the clamping strip and the fixed mold ensures the structural stability of the clamping strip and simplifies the mold's assembly and maintenance process, reducing usage and maintenance costs and demonstrating high practical value.

[0025] The technical solution of this utility model will now be described with reference to the accompanying drawings and embodiments.

[0026] Please see Figure 1-7 This embodiment provides the following technical solution: an integrated molding mold for an automotive air vent guide vane, including a fixed mold 1 and a movable mold 2. The movable mold 2 has a sub-mold 9 in the middle that can move along the vane 16. The surface of the sub-mold 9 is provided with a vane mold core 10 for injection molding of the vane 16. The upper surface of the fixed mold 1 is integrally formed with a retaining strip 12. The connection between the fixed mold 1, the movable mold 2, the sub-mold 9 and the retaining strip 12 is provided with an air vent mold core 8 for injection molding of the air vent 15. The air vent mold core 8 is connected to the vane mold core 10. The surface of the sub-mold 9 near the fixed mold 1 is provided with a connecting groove 11, and the connecting groove 11 is perpendicular to the vane mold core 10. The end of the movable mold 2 away from the fixed mold 1 is provided with a demolding member, and one end of the demolding member is located inside the air vent mold core 8.

[0027] In this embodiment, a sub-mold 9 that can move along the blade 16 is provided in the middle of the moving mold 2. At the same time, an air guide core 8 for the air guide 15 to be formed during injection molding is provided at the connection of the fixed mold 1, the moving mold 2, the sub-mold 9 and the retaining strip 12. The retaining strip 12 is integrally formed on the upper surface of the fixed mold 1 to prevent the blade 16, which has an inclined structure, from being injection molded in the blade core 10. This would prevent the air guide core 8 from being difficult to remove from the moving mold 2. At the same time, the moving mold 2, the air guide core 8 and the retaining strip 12 adopt a split structure, which makes it easy for the air guide 15 inside the air guide core 8 to be demolded under the action of the demolding component when the moving mold 2 moves upward. This makes it easy for the injection molded part to be located on the upper surface of the fixed mold 1 after demolding, and easy to remove the injection molded part. This makes it easy to integrally form the air guide blade of the car air outlet.

[0028] Specifically, the demolding component includes a demolding cavity 4 opened on the upper surface of the moving mold 2. A cover plate 3 for protecting the demolding cavity 4 is installed on the upper surface of the moving mold 2. The demolding cavity 4 is located outside the air guide mold core 8. A demolding rod 5 is movably installed in the demolding cavity 4. One end of the demolding rod 5 extends into the air guide mold core 8, and the other end of the demolding rod 5 extends outside the cover plate 3. A baffle 6 is welded to the surface of the demolding rod 5 located in the demolding cavity 4. A spring 7 is fixed on the lower surface of the baffle 6. Two demolding components are symmetrically arranged, and the demolding rods 5 installed in each demolding cavity 4 are distributed in a linear array.

[0029] In this embodiment, a demolding component consisting of a demolding cavity 4, a demolding rod 5, a baffle 6, and a spring 7 is used. The demolding rod 5 is movably installed in the demolding cavity 4 opened on the upper surface of the moving mold 2. One end of the demolding rod 5 passes through the moving mold 2 and extends into the air guide mold core 8, while the other end of the demolding rod 5 passes through the cover plate 3. This allows the baffle 6 welded to the surface of the demolding rod 5 to be tightly attached to the surface of the cover plate 3 under the action of the spring 7. When the upper end of the demolding rod 5 is squeezed by external force, the demolding rod 5 carries the air guide 15 in the air guide mold core 8 for demolding, thereby achieving the purpose of demolding the injection molded part through the demolding component.

[0030] Specifically, four linkage cylinders 13 are installed on the upper surface of the cover plate 3, and the inlet and outlet ends of the four linkage cylinders 13 are connected by two inlet and outlet pipes respectively. The telescopic end of the linkage cylinder 13 is equipped with a linkage rod 14, and the linkage rod 14 is fixed on the upper surface of the sub-mold 9. The linkage cylinder 13 is parallel to the blade mold core 10.

[0031] In this embodiment, four linkage cylinders 13 are installed on the upper surface of the cover plate 3. The air inlet and outlet ends of the four linkage cylinders 13 are connected by two air inlet and outlet pipes, which facilitates the linkage of the four linkage cylinders 13. The linkage rod 14 installed on the telescopic end of the linkage cylinder 13 is fixed on the upper surface of the sub-mold 9, which facilitates the telescopic end of the linkage cylinder 13 to slide the sub-mold 9 in the middle of the moving mold 2 through the linkage rod 14. At the same time, the linkage cylinder 13 is parallel to the blade mold core 10, which facilitates the sub-mold 9 to move along the inclined direction of the air guide 15 when the injection molded part is demolded.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
