Description

Technical Field

[0001] This utility model relates to the field of profile processing technology, and in particular to a heat dissipation and demolding structure for improving the mechanical properties of profiles. Background Technology

[0002] Profiles, due to their diverse cross-sectional shapes and sizes, are widely used in fields such as construction, machinery, and transportation. Their mechanical properties directly determine the safety, stability, and durability of the structure.

[0003] However, when using traditional demolding structures to improve profile mechanical properties, the injection molded profile will generate heat. The lack of internal heat dissipation structure will lead to a longer cooling cycle and low heat dissipation efficiency. For example, in the profile processing, heat dissipation and demolding are key links affecting product quality. Insufficient heat dissipation efficiency will lead to a longer cooling cycle and affect demolding time. Utility Model Content

[0004] This utility model discloses a heat dissipation demolding structure for improving the mechanical properties of profiles. It aims to solve the technical problem that when traditional demolding structures for improving the mechanical properties of profiles are used, the injection-molded profiles generate heat, and the lack of internal heat dissipation structure leads to a prolonged cooling cycle and low heat dissipation efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A heat dissipation and demolding structure for improving profile mechanical properties includes a connecting frame and a first mold and a second mold disposed on one side of the connecting frame, and further includes: Demolding mechanism: The demolding mechanism is provided on the first mold; The first mold has a first cavity on one side of its outer wall, and a limiting fixture is provided on the inner wall of the first cavity. The inner wall of the limiting fixture is provided with heat dissipation fins that are evenly distributed. The second mold has a second cavity on one side of its outer wall, and a limiting plate is provided on the inner wall of the second cavity that is evenly distributed. The first cavity and the second cavity are used in conjunction.

[0006] In this solution, the first mold and the second mold are close together to perform injection molding of the profile. The shape of the profile is defined by the combination of the first cavity and the second cavity and the limiting plate, forming a profile with multiple teeth. Inside the first cavity, the heat dissipation fins filled in the limiting fixture dissipate heat from the formed profile. The structure is simple, saves time for subsequent demolding, and has a good heat dissipation effect.

[0007] In a preferred embodiment, the demolding mechanism includes a hard chrome film disposed on the inner wall of the limiting clamp, a mounting seat disposed on one side of the inner wall of the connecting frame, and an electric telescopic rod disposed on one side of the outer wall of the mounting seat, the piston end of the electric telescopic rod passing through the first mold and communicating with the hard chrome film.

[0008] By adopting the above technical solution, a hard chrome film is plated inside the limiting fixture to give the surface sliding properties, which can effectively resist wear, scratches and impacts, thereby protecting the profile. It also has high temperature resistance and is not affected by the injection molding process. After the profile is injected, the second mold is removed, and the electric telescopic rod works to push the profile to demold. With the hard chrome film, the demolding effect is good.

[0009] As can be seen from the above, the heat dissipation and demolding structure for improving the mechanical properties of the profile includes a connecting frame and a first mold and a second mold disposed on one side of the connecting frame, and also includes: Demolding mechanism: The demolding mechanism is provided on the first mold; The first mold has a first cavity on one outer wall, and a limiting clamp is provided on the inner wall of the first cavity. The inner wall of the limiting clamp has evenly distributed heat dissipation fins. The second mold has a second cavity on one outer wall, and the inner wall of the second cavity has evenly distributed limiting plates. The first cavity and the second cavity work together. The heat dissipation and demolding structure for improving profile mechanical properties provided by this invention dissipates heat from the injection-molded profile through heat dissipation fins, resulting in good heat dissipation, saving demolding time, and making demolding smoother.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0016] The heat dissipation and demolding structure for improving profile mechanical properties disclosed in this utility model is mainly applied to scenarios where traditional demolding structures for improving profile mechanical properties are used, injection molded profiles generate heat, and the lack of internal heat dissipation structures leads to prolonged cooling cycles and low heat dissipation efficiency.

[0017] Reference Figure 1 , Figure 2 and Figure 3 The heat dissipation and demolding structure for improving the mechanical properties of profiles includes a connecting frame 1 and a first mold 2 and a second mold 3 disposed on one side of the connecting frame 1, and also includes: Demolding mechanism: The demolding mechanism is located on the first mold 2; The first mold 2 has a first cavity 6 on one side of its outer wall. The inner wall of the first cavity 6 is provided with a limiting clamp 7. The inner wall of the limiting clamp 7 is filled with heat dissipation fins 11 that are evenly distributed. The second mold 3 has a second cavity 10 on one side of its outer wall. The inner wall of the second cavity 10 is provided with limiting plates 13 that are evenly distributed. The first cavity 6 and the second cavity 10 are used together.

[0018] In the specific working process, the first mold 2 is fixed on the connecting frame 1, and the second mold 3 is movable. The profile is injection molded by the first mold 2 and the second mold 3 approaching each other. The first cavity 6 and the second cavity 10 that fit together, together with the limiting plate 13, limit the shape of the profile to form a profile with multiple teeth. The heat dissipation fins 11 filled in the limiting clamp 7 inside the first cavity 6 dissipate heat from the formed profile. The heat dissipation fins 11 dissipate heat at the same time as the profile is injection molded.

[0019] The first cavity 6 and the second cavity 10 are positioned correspondingly. The limiting plate 13 is adapted to the first cavity 6. The first cavity 6 and the second cavity 10 are combined to form the shape of the profile. The first cavity 6 extends to the inclined side of the second cavity 10, which is more conducive to subsequent demolding. The limiting plate 13 is adapted to the first cavity 6 to limit and make the profile form a tooth shape. The profile formed by injection molding itself has a heat dissipation effect.

[0020] Among them, the heat dissipation fins 11 are made of copper-aluminum composite material. The structure of the heat dissipation fins 11 enhances convective heat transfer. The copper-aluminum composite material + fin structure achieves efficient heat dissipation, meets heat dissipation requirements, and dissipates heat from the profile.

[0021] It should be noted that the limiting plate 13 in the second cavity 10 is set in this solution to make the profile form a tooth shape, so that the distance between the profiles can form a heat dissipation space. The profiles used later can have a heat dissipation effect. The structure of the first cavity 6 and the second cavity 10 can be determined according to the shape of the injection molded profile, and the formation of the cavity can be determined according to the actual situation.

[0022] Reference Figure 1 and Figure 2 In a preferred embodiment, the second mold 3 has an injection hole 5 and two flanges 4 on the outer wall of the side away from the second cavity 10. The injection hole 5 is located in the center of the second mold 3. The inner wall of the second mold is provided with a guide plate 9. The injection hole 5 and the guide plate 9 are connected. The outer wall of one side of the guide plate 9 has guide holes that are evenly distributed. The guide holes are staggered with the limiting plate 13.

[0023] Specifically, telescopic components are installed on the outside of the second mold 3 via two flanges 4, which drive the second mold 3 to move towards the first mold 2. Injection is performed at the injection hole 5. The injection material is introduced into the guide plate 9 through the injection hole 5, then flows into the guide hole, and then is injected into the second cavity 10 and the first cavity 6 through the guide hole. The guide hole and the limiting plate 13 are intersected, the injection is sufficient, and the profile is easier to form a tooth shape.

[0024] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the demolding mechanism includes a hard chrome film 12 plated on the inner wall of the limiting clamp 7, a mounting seat 8 is provided on one side of the inner wall of the connecting frame 1, and an electric telescopic rod 14 is provided on one side of the outer wall of the mounting seat 8. The piston end of the electric telescopic rod 14 passes through the first mold 2 and communicates with the hard chrome film 12.

[0025] Specifically, a hard chrome film 12 is plated inside the limiting clamp 7 to give the surface sliding properties, which can effectively resist wear, scratches and impacts, thereby protecting the profile. It also has high temperature resistance and is not affected by the injection molding process. After the profile is injected, the second mold 3 is removed, and the electric telescopic rod 14 works to push the profile to demold. With the hard chrome film 12, it is more conducive to the demolding work.

[0026] The electric telescopic rod 14 and the hard chrome film 12 are used together. The sliding performance of the hard chrome film 12 can assist in demolding when the electric telescopic rod 14 pushes the profile, which is more conducive to demolding and has a good working effect.

[0027] Working principle: During use, the telescopic assembly connected by the flange 4 moves the second mold 3 to the position of the first mold 2, so that the first cavity 6 and the second cavity 10 fit together. With the help of the limiting plate 13, the shape of the profile is limited. The injection material is injected into the guide plate 9 at the injection hole 5. The material is guided through the guide holes on the guide plate 9 and injection is performed in the first cavity 6 and the second cavity 10. During the injection process, the limiting clamp 7 limits the shape of the first cavity 6, while the internal heat dissipation fins 11 dissipate heat from the profile. After the injection is completed, the second mold 3 is removed, and the electric telescopic rod 14 works. With the sliding performance of the hard chrome film 12, the profile is better pushed for demolding.

[0028] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
