Description

Technical Field

[0001] This utility model relates to the field of thermal conductive structure manufacturing technology, and in particular to an extrusion molding structure for a large-volume thermal conductive structure. Background Technology

[0002] With the development of society, electronic products have become closely related to people's lives, and people's requirements for product quality are getting higher and higher. In order to improve product quality and enable it to work stably, every electronic product is equipped with at least one heat dissipation component. The core heat-conducting structure in the heat dissipation component is generally a heat-conducting material that is molded by potting glue in an aluminum-plastic film and uniformly shaped by the aluminum-plastic film. The core of the quality of this heat-conducting structure is the uniformity of the internal heat-conducting material and the uniformity of the thickness of the entire heat-conducting structure.

[0003] However, unlike the small thermal conductive structures in small electronic products, the thermal conductive structures in large electronic products are much larger. It is difficult to ensure that the thermal conductive material is uniform within such a large thermal conductive structure, and it is also difficult to ensure that the thickness of the entire thermal conductive structure is uniform after the colloid is poured into the aluminum-plastic film and the colloid stabilizes. Utility Model Content

[0004] The main purpose of this utility model is to provide an extrusion molding structure with a large volume thermally conductive structure, which aims to improve product quality and achieve uniform and stable product thickness.

[0005] To achieve the above objectives, this utility model proposes an extrusion molding structure for a large-volume thermally conductive structure, comprising a molding component, wherein a reference structure is provided on one side of the molding component and an extrusion structure is provided on the other side, the extrusion structure and the reference structure are parallel to each other and clamped together to form a molding cavity, and the reference structure is provided with a clamping structure passing through the molding cavity.

[0006] The molding component has multiple first guide rods arranged in an array, which are vertically connected to the reference structure. The extrusion structure is connected to the multiple first guide rods. The multiple first guide rods are connected to both sides of the molding cavity and are symmetrically arranged along the molding cavity. The outer periphery of the top of the molding component is provided with a connecting structure that surrounds the molding cavity.

[0007] In one embodiment of this application, the extrusion structure includes an extrusion surface parallel to the reference structure and a pushing structure connected to the outer periphery of the molding component and connected to the extrusion surface. The pushing structure is provided in multiple ways, and the multiple pushing structures are arrayed and connected to the extrusion surface.

[0008] In one embodiment of this application, the pressing structure includes a stabilizing frame connected to the outer periphery of the molding component and a pressing surface connected to the side of the extrusion surface away from the molding cavity. The stabilizing frame is provided with a first driving member, the first driving member is connected to a driving surface, and a second guide rod parallel to the first guide rod is provided between the pressing surface and the driving surface.

[0009] In one embodiment of this application, the stabilizer is provided with a plurality of third guide rods that are parallel to the second guide rods and connected to the drive surface, and the plurality of third guide rods are wrapped around the first drive member.

[0010] In one embodiment of this application, the clamping structure includes a second driving member connected to the molding assembly, and a clamping assembly connected to one end of the second driving member and disposed toward the molding cavity, the clamping assembly being connected to a reference structure;

[0011] The clamping assembly includes a fixed clamping structure connected to the reference structure and a movable clamping structure connected to the second driving member, wherein the fixed clamping structure and the movable clamping structure are clamped together to form a fixing part.

[0012] In one embodiment of this application, the movable clamping structure is connected to the side of the fixed clamping structure opposite to the second driving member, and the fixed clamping structure is provided with a guide groove connected to the movable clamping structure relative to the second driving member.

[0013] In one embodiment of this application, the fixed clamping structure includes a connecting seat connected to a reference structure, a connecting block connected to the connecting seat, and a clamping claw connected to the connecting block on the side facing the movable clamping structure. The connecting seat is provided with a balance bar along a direction perpendicular to the movement of the movable clamping structure. The connecting block is connected to the balance bar. A stabilizing spring connected to the balance bar is provided between the connecting seat and the connecting block.

[0014] In one embodiment of this application, the molding component is provided with at least two sets of reference structures and at least two sets of extrusion structures relative to the two sets of reference structures.

[0015] By adopting the above technical solution, this utility model has the following advantages:

[0016] The purpose of this application is to address the potential issues of unstable heat-conducting materials and uneven product thickness in the manufacturing process of large-volume integrated heat-conducting structures. The problems in the manufacturing process of heat-conducting structures stem from the fact that the raw materials for heat-conducting materials generally consist of at least two solutions, which need to be injected into an aluminum-plastic film to allow the different solutions to react. Once the reaction stabilizes, a flexible gel-like heat-conducting material is obtained, and the aluminum-plastic film is then sealed to form the finished heat-conducting structure. During the reaction of different solutions, a large number of bubbles may appear, leading to unevenness in the finished heat-conducting material. Furthermore, in large-volume heat-conducting structures, the large area of ​​the aluminum-plastic film and the large amount of solution used result in difficulties in homogenization and molding.

[0017] To address the aforementioned issues, the main structure of this application is a molding assembly, primarily used to connect and hold the aluminum-plastic film. The molding assembly has a connecting structure on its outer periphery. This connecting structure allows the external structure (such as the glue-filling structure) to be sealed to the molding assembly when the aluminum-plastic film is mounted and the heat-conducting structure is temporarily shaped. This prevents air leakage within the molding assembly's cavity during heat-conducting structure processing. To ensure uniform thickness of the heat-conducting structure, a reference structure is located on one side of the molding assembly, and an extrusion structure on the other. A molding cavity for accommodating the heat-conducting structure is located between these two structures. The reference structure ensures stable shaping of the heat-conducting structure and serves as a reference surface. Simultaneously, a clamping structure connected to the molding cavity is located on the reference structure. This clamping structure can hold the top of the aluminum-plastic film, allowing the entire film to unfold for easy glue filling and shaping. The extrusion structure is parallel to the reference structure, ensuring a more uniform heat-conducting structure after the extrusion structure moves towards the reference structure. Through the cooperation of these structures, the entire glue-filling mechanism is highly integrated, and the different structures can work together seamlessly, ensuring stable processing efficiency and quality.

[0018] Multiple first guide rods are installed inside the molding assembly. The reference structure and the extrusion surface are both connected to the first guide rods. The guide rods can limit the movement path of the extrusion surface, ensure the uniformity of the force on the entire heat-conducting structure, and enable the extrusion surface to move parallel to the reference structure. The multiple first guide rods can limit the molding cavity and ensure the structural stability of the molding cavity. Attached Figure Description

[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] Reference Figures 1 to 3 To achieve the above objectives, this utility model proposes an extrusion molding structure for a large-volume thermally conductive structure, including a molding component 1. A reference structure 2 is provided on one side of the molding component 1, and an extrusion structure 4 is provided on the other side. The extrusion structure 4 and the reference structure 2 are parallel to each other and clamped together to form a molding cavity. A clamping structure 3 is provided on the reference structure 2 and passes through the molding cavity.

[0028] The molding component 1 has multiple first guide rods 11 arranged in an array and vertically connected to the reference structure 2. The extrusion structure 4 is connected to the multiple first guide rods 11. The multiple first guide rods 11 are connected to both sides of the molding cavity and are symmetrically arranged along the molding cavity. The outer periphery of the top of the molding component 1 is provided with a connecting structure 12 that surrounds the molding cavity.

[0029] The purpose of this application is to address the potential issues of unstable heat-conducting materials and uneven product thickness in the manufacturing process of large-volume integrated heat-conducting structures. The problems in the manufacturing process of heat-conducting structures stem from the fact that the raw materials for heat-conducting materials generally consist of at least two solutions, which need to be injected into an aluminum-plastic film to allow the different solutions to react. Once the reaction stabilizes, a flexible gel-like heat-conducting material is obtained, and the aluminum-plastic film is then sealed to form the finished heat-conducting structure. During the reaction of different solutions, a large number of bubbles may appear, leading to unevenness in the finished heat-conducting material. Furthermore, in large-volume heat-conducting structures, the large area of ​​the aluminum-plastic film and the large amount of solution used result in difficulties in homogenization and molding.

[0030] To address the aforementioned issues, the main structural component of this application is a molding assembly 1, primarily used for connecting and placing the aluminum-plastic film. A connecting structure 12 is provided on the outer periphery of the molding assembly 1. Through the connecting structure 12, when the molding assembly 1 is fitted with the aluminum-plastic film and undergoes temporary shaping of the heat-conducting structure, the external structure (such as the glue-filling structure) can be sealed to the molding assembly 1, preventing air leakage within the molding assembly 1 during heat-conducting structure processing. To ensure uniform overall thickness of the heat-conducting structure, a reference structure 2 is provided on one side of the molding assembly 1, and an extrusion structure 4 is provided on the other side. A molding cavity for accommodating the heat-conducting structure to be processed is provided between the two structures. The reference structure 2 ensures the stability of the heat-conducting structure shaping and serves as a reference surface supporting the heat-conducting structure. Simultaneously, a clamping structure 3 connected to the molding cavity is provided on the reference structure 2. The clamping structure 3 can clamp the top of the aluminum-plastic film, allowing the entire aluminum-plastic film to unfold, facilitating glue filling and shaping. The extrusion structure 4 is parallel to the reference structure 2, ensuring a more uniform heat-conducting structure after the extrusion structure 4 moves towards the reference structure 2. The above structures work together to ensure a high degree of integration of the entire dispensing mechanism, and the different structures can cooperate closely to ensure stable processing efficiency and quality.

[0031] Multiple first guide rods 11 are provided inside the molding component 1. The reference structure 2 and the extrusion surface 41 are both connected to the first guide rods 11. The guide rods can restrict the movement path of the extrusion surface 41, ensuring the uniformity of the force on the entire heat-conducting structure, so that the extrusion surface 41 can move parallel to the reference structure 2. The multiple first guide rods 11 can limit the molding cavity, ensuring the structural stability of the molding cavity.

[0032] See also Figures 1 to 2 The extrusion structure 4 includes an extrusion surface 41 parallel to the reference structure 2 and a pushing structure 5 connected to the outer periphery of the molding component 1 and connected to the extrusion surface 41. Multiple pushing structures 5 are provided, and multiple pushing structures 5 are arrayed and connected to the extrusion surface 41.

[0033] The extrusion surface 41 is parallel to the reference structure 2, which can ensure that the thickness of the entire heat-conducting structure is consistent when the extrusion surface 41 is working. Multiple pushing structures 5 jointly drive the extrusion surface 41 to ensure the high integration of the entire structure. At the same time, it ensures that the end of the extrusion surface 41 away from the forming cavity is subjected to uniform force, which can prevent the aluminum-plastic film from being damaged and ensure that the thickness of the heat-conducting structure is consistent.

[0034] See also Figure 2 The pressing structure 5 includes a stabilizing frame 51 connected to the outer periphery of the molding component 1 and a pressing surface 52 connected to the side of the extrusion surface 41 away from the molding cavity. The stabilizing frame 51 is provided with a first driving member 53, which is connected to the driving surface. A second guide rod parallel to the first guide rod 11 is provided between the pressing surface 52 and the driving surface.

[0035] A set of pressing structures 5 includes a stabilizing component for ensuring the stable installation of the pressing structure 5 and a pressing surface 52 connected to the extrusion surface 41. The pressing surface 52 drives the extrusion surface 41, which can increase the contact area between the two and ensure uniform force. The stabilizing component is provided with a first driving component 53 (generally a cylinder, but it can also be a motor). The first driving component 53 drives and connects to the driving surface. Multiple second guide rods are provided between the driving surface and the pressing surface 52, which can shorten the connecting rod length between the driving component and the pressing surface 52 and ensure the stability of the movement of the pressing surface 52.

[0036] See also Figure 2 The stabilizer 51 is provided with multiple third guide rods 54 that are parallel to the second guide rods and connected to the drive surface, and the multiple third guide rods 54 surround the first drive member 53. The third guide rods 54 can limit the drive surface and ensure the stability of the drive surface's movement path.

[0037] See also Figures 1 to 3 The clamping structure 3 includes a second driving member 31 connected to the molding component 1, and a clamping component 32 connected to one end of the second driving member 31 and disposed toward the molding cavity. The clamping component 32 is connected to the reference structure 2.

[0038] The clamping assembly 32 includes a fixed clamping structure 33 connected to the reference structure 2 and a movable clamping structure 36 connected to the second drive member 31. The fixed clamping structure 33 and the movable clamping structure 36 are clamped together to form a fixing part.

[0039] The clamping structure 3 includes a clamping component 32 for fixing the aluminum-plastic film and a second driving component 31 for driving the clamping component 32 to open and close. At the same time, the clamping structure 3 generally has at least two symmetrically arranged clamping components 32 for each molding cavity, which ensures that the clamping structure 3 can stably grasp the aluminum-plastic film and improve the molding efficiency of the heat-conducting structure.

[0040] The clamping assembly 32 itself includes a fixed clamping structure 33 for stability and a movable clamping structure 36 connected to the second drive member 31. The fixing part composed of the two structures can ensure the extrusion molding efficiency.

[0041] See also Figure 3 The movable clamping structure 36 is connected to the fixed clamping structure 33 on the side opposite to the second driving member 31. The fixed clamping structure 33 is provided with a guide groove connected to the movable clamping structure 36 relative to the second driving member 31.

[0042] The guide groove can restrict the second driving member 31, which can ensure the stability of the movement of the second driving member 31, thereby making the movement of the moving clamp structure 36 more stable. The moving clamp structure 36 is provided with a fixed clamp structure 33 on the side opposite to the second driving member 31, which can ensure that the moving clamp structure 36 can stably approach the fixed clamp structure 33, thus ensuring the stability of the clamping operation.

[0043] See also Figure 3 The fixed clamping structure 33 includes a connecting seat 34 connected to the reference structure 2, a connecting block 35 connected to the connecting seat 34, and a clamping claw connected to the connecting block 35 on the side facing the movable clamping structure 36. The connecting seat 34 is provided with a balance bar along the moving direction perpendicular to the movable clamping structure 36. The connecting block 35 is connected to the balance bar. A stabilizing spring connected to the balance bar is provided between the connecting seat 34 and the connecting block 35.

[0044] The clamping structure 33 itself includes a connecting seat 34 and a connecting block 35. The connecting seat 34 is used for the reference structure 2 and is equipped with a balance bar. Because the aluminum-plastic film filled with solution is heavy and may shake when the solution is filled, the connecting block 35 with grippers is connected to the balance bar and is equipped with a stabilizing spring relative to the connecting seat 34, which can reduce the pressure on the clamping structure 3 and improve the service life of the clamping structure 3.

[0045] See also Figure 1 The molding component 1 is provided with at least two sets of reference structures 2 and at least two sets of extrusion structures 4 relative to the two sets of reference structures 2.

[0046] By setting multiple sets of reference structures 2 and multiple sets of extrusion structures 4 in the molding component 1, it is possible to process multiple heat-conducting structures in one operation, which can effectively improve the processing speed.
