Description

Technical Field

[0001] The utility model relates to the application field of 3C product extrusion molding technology, in particular to an extrusion molding device for 3C products. Background Art

[0002] 3C products refer to three types of electronic products: computers, communications, and consumer electronics. When producing aluminum alloy 3C products, punching machines and molds are used to produce the required shapes. Punching machines can be either mechanically driven or hydraulically driven.

[0003] Existing technology requires technicians to reach under the upper extrusion die during material loading, posing a safety hazard. Publication number CN220072937U, titled "A Precision Extrusion Molding Apparatus for High-Brightness Aluminum Alloy Sheets for 3C Products," discloses a mobile loading assembly that separates the extrusion and preparation areas to improve production safety. However, this technology inevitably impacts the linearly moving lead screws, guide rods, and sliders during the extrusion process. After a period of use, the lower die can become stuck and unable to move.

[0004] Similarly, due to production requirements, when different models of products need to be processed, the lower mold cannot be quickly replaced.

[0005] In summary, there is an urgent need to provide an extrusion molding device for 3C products. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an extrusion molding device for 3C products. The use of this device not only realizes the separation of the extrusion area and the preparation area, but also ensures the smoothness of the movement process.

[0007] The technical solution of the utility model is: an extrusion molding device for 3C products, comprising a base, the base being provided with a processing platform, the processing platform having two areas, namely an extrusion area and a material preparation area, the processing platform being provided with a lower die, and the lower die being able to linearly move back and forth between the extrusion area and the material preparation area along the length direction of the processing platform;

[0008] It also includes a driving assembly arranged on the processing platform and driving the lower mold to move. An L-shaped connecting rod is supported at one end of the lower mold, and the L-shaped connecting rod is connected to the telescopic end of the driving assembly.

[0009] Furthermore, the processing platform is provided with a T-shaped slot, and the bottom of the lower mold is provided with a T-shaped block used in conjunction with the T-shaped slot. The T-shaped block is clamped in the T-shaped slot and moves along the length direction of the T-shaped slot.

[0010] Furthermore, the L-shaped connecting rod is provided with a through hole, and the telescopic end of the driving assembly cooperates with the through hole through the connecting rod to connect the driving assembly to the lower mold.

[0011] Furthermore, the connecting rod has three parts: a left rod, a middle rod and a right rod. The left rod is connected to the telescopic end of the drive assembly, the middle rod is located in the through hole, and the right rod is bolted to the middle rod. The L-shaped connecting rod is fixed through the left rod and the right rod.

[0012] Furthermore, the outer diameter of the middle rod is smaller than the inner diameter of the through hole, and the length of the middle rod is greater than the width of the L-shaped connecting rod.

[0013] Furthermore, an elastic member is provided at the bottom of the L-shaped connecting rod, one end of the elastic member is movably connected to the L-shaped connecting rod, and the other end of the elastic member abuts against the base.

[0014] Furthermore, the elastic member includes a sliding rod inserted into the L-shaped connecting rod, a spring sleeved on the surface of the sliding rod and a support seat fixed to the sliding rod, and the bottom of the support seat is in contact with the base through a ball bearing.

[0015] Furthermore, the processing platform is provided with a limit block, and the lower die is provided with a limit groove used in conjunction with the limit block.

[0016] Furthermore, a position sensor is provided in the T-slot.

[0017] Furthermore, the base is also provided with a mounting seat, and the mounting seat is equipped with an extrusion assembly for use with the lower mold through a support rod.

[0018] The beneficial technical effects of the utility model are:

[0019] 1. The processing platform is equipped with two areas, including the extrusion area and the material preparation area. By separating the two areas, the problem of personnel continuing to prepare materials under the extrusion assembly after extrusion is completed is solved;

[0020] When the lower die moves to the material preparation area, the lower die is away from the bottom of the extrusion assembly, making it convenient for personnel to prepare materials on the lower die; after the material preparation is completed, the lower die moves to the bottom of the extrusion assembly and waits for the product to be extruded; after the extrusion is completed, the lower die moves to the material preparation area and personnel change the product.

[0021] 2. The connecting rod consists of three parts: the left rod, the middle rod and the right rod. When the extrusion assembly abuts against the lower die and squeezes the product on the lower die, it will inevitably generate a certain impact force on the lower die. In order to avoid the stability of the connection between the lower die and the driving assembly, the outer diameter of the middle rod is smaller than the inner diameter of the through hole to reduce the impact force on the telescopic end of the driving assembly, thereby improving the service life of the driving assembly and ensuring the stability of the linear movement process of the lower die.

[0022] 3. The setting of the elastic part at the bottom of the L-shaped connecting rod also provides a certain buffer for the impact force of the drive assembly, ensuring that the telescopic end of the drive assembly will not be easily deformed, thereby ensuring the stability of the linear movement of the lower mold.

[0023] 4. The ball bearing at the bottom of the support seat abuts against the base, which not only ensures the buffering of the connection between the lower die and the telescopic end, but also improves the smoothness of the linear movement of the lower die.

[0024] 5. The setting of the limit block ensures the position accuracy of the lower die. At the same time, it is further determined by the position sensor. When the lower die reaches the specified extrusion position, the lower die abuts against the limit block, and the position sensor senses the lower die, and the extrusion assembly performs the extrusion action.

[0025] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and to implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0032] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

Therefore, they cannot be understood as a limitation on the present utility model.

[0035] like Figures 1-4 As shown, the present invention specifically relates to an extrusion molding device for 3C products, including a base 100, the base 100 is provided with a processing platform 120, the processing platform 120 has two areas, namely an extrusion area 121 and a preparation area 122, the processing platform 120 is provided with a lower mold 130, and the lower mold 130 can move linearly back and forth between the extrusion area 121 and the preparation area 122 along the length direction of the processing platform 120;

[0036] The processing platform 120 further includes a driving assembly 110 that is disposed on the processing platform 120 and drives the lower mold 130 to move. An L-shaped connecting rod 132 is supported at one end of the lower mold 130 , and the L-shaped connecting rod 132 is connected to the telescopic end of the driving assembly 110 .

[0037] It should be noted that the processing platform 120 is an integrated molding structure, and the extrusion area 121 and the preparation area 122 are only on the left and right sides of the processing platform 120. The lower mold 130 is slidably connected to the processing platform 120 and can move linearly relative to the processing platform 120. When the lower mold 130 moves to the extrusion area 121, it completes the extrusion action; when the lower mold 130 moves to the preparation area 122, it completes the action of replacing or placing the product.

[0038] The driving assembly 110 is fixed to one side of the processing platform 120 , and the telescopic end of the driving assembly 110 is connected to the lower mold 130 via an L-shaped connecting rod 132 to provide a power source for the lower mold 130 to move.

[0039] In addition, the driving assembly 110 is a mechanism that can drive components to move linearly, and can be an oil cylinder, a hydraulic cylinder, or a pneumatic cylinder, etc. In this embodiment, the preferred one can be selected according to actual usage.

[0040] The processing platform 120 is provided with a T-slot 123 , and the bottom of the lower mold 130 is provided with a T-block used to cooperate with the T-slot 123 . The T-block is clamped in the T-slot 123 and moves along the length direction of the T-slot 123 .

[0041] The arrangement of the T-slot 123 and the T-block ensures that the lower die 130 can only move linearly along the length direction of the T-slot 123, ensuring that the lower die 130 will not be offset in position; in addition, the T-slot 123 and the T-block cooperate with each other so that the lower die 130 can move relative to the processing platform 120.

[0042] The L-shaped connecting rod 132 is provided with a through hole, and the telescopic end of the driving assembly 110 is used in conjunction with the through hole through the connecting rod 133 to connect the driving assembly 110 with the lower mold 130, avoiding direct connection between the telescopic end of the driving assembly 110 and the L-shaped connecting rod 132, so as to slightly reduce the impact force received by the telescopic end of the driving assembly 110.

[0043] The connecting rod 133 has three parts: a left rod 1331, a middle rod 1332 and a right rod 1333. The left rod 1331 is connected to the telescopic end of the driving assembly 110, the middle rod 1332 is located in the through hole, and the right rod 1333 is bolted to the middle rod 1332. The L-shaped connecting rod 132 is fixed by the left rod 1331 and the right rod 1333.

[0044] Among them, the left rod 1331 and the middle rod 1332 are an integrally formed structure, and the right rod 1333 is connected to the middle rod 1332 by bolts to fix the L-shaped connecting rod 132; in addition, when the lower mold 130 needs to be replaced, the drive assembly 110 moves the lower mold 130 to the preparation area 122. At this time, it is only necessary to separate the right rod 1333 from the middle rod 1332, and then move the lower mold 130 out of the processing platform 120 along the length direction of the T-slot 123.

[0045] Furthermore, there is a gap between the left rod 1331 and the L-shaped connecting rod 132 , and similarly, there is a gap between the right rod 1333 and the L-shaped connecting rod 132 .

[0046] The outer diameter of the middle rod 1332 is smaller than the inner diameter of the through hole, and the length of the middle rod 1332 is greater than the width of the L-shaped connecting rod 132. When the lower mold 130 is subjected to impact force, the impact force is transmitted to the L-shaped connecting rod 132 through the lower mold 130. Since there is a certain amount of movable space between the middle rod 1332 and the through hole, the impact force is avoided from being transmitted to the driving assembly 110, thereby ensuring the smoothness of the movement process of the lower mold 130.

[0047] An elastic member 134 is provided at the bottom of the L-shaped connecting rod 132, one end of the elastic member 134 is movably connected to the L-shaped connecting rod 132, and the other end of the elastic member 134 abuts against the base 100. The setting of the elastic member 134 at the bottom of the L-shaped connecting rod 132 also provides a certain buffer for the impact force of the driving component 110, ensuring that the telescopic end of the driving component 110 will not be easily deformed, thereby ensuring the stability of the linear movement of the lower mold 130.

[0048] The elastic member 134 includes a sliding rod inserted into the L-shaped connecting rod 132, a spring sleeved on the surface of the sliding rod and a support seat fixed to the sliding rod. The bottom of the support seat is in contact with the base 100 through a ball bearing. The ball bearing at the bottom of the support seat is in contact with the base 100, which not only ensures the buffering of the connection between the lower mold 130 and the telescopic end, but also improves the smoothness of the linear movement of the lower mold 130.

[0049] The processing platform 120 is provided with a limit block 125 , and the lower die 130 is provided with a limit slot 131 used to cooperate with the limit block 125 ; a position sensor 124 is provided in the T-slot 123 .

[0050] The setting of the limit block 125 ensures the position accuracy of the lower mold 130, and is further determined by the position sensor 124. When the lower mold 130 reaches the specified extrusion position, the lower mold 130 abuts against the limit block 125, and the position sensor 124 senses the lower mold 130, and the extrusion assembly 400 performs the extrusion action.

[0051] The base 100 is further provided with a mounting seat 200 , and the mounting seat 200 is equipped with an extrusion assembly 400 used in conjunction with the lower mold 130 via a support rod 300 .

[0052] The above embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solutions of the present invention rather than to limit them. The protection scope of the present invention is not limited thereto. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in this field should understand that any technician familiar with this technical field can still modify the technical solutions recorded in the above embodiments within the technical scope disclosed by the present invention, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
