Description

Technical Field

[0001] This invention relates to an extrusion apparatus, and more particularly to a copper extrusion forming apparatus. Background Technology

[0002] Copper is a soft metal material. However, during extrusion molding, the gas inside the extrusion area cannot be properly discharged, which affects the product size and requires additional secondary processing. In severe cases, it can even cause the mold to burst. Currently, polishing the lower mold insert can prevent the mold from bursting to some extent, but it still cannot guarantee the product's dimensional accuracy. Summary of the Invention

[0003] The present invention provides a copper extrusion molding device, which can solve the problem of mold bursting caused by the inability of internal gas to be discharged during copper extrusion molding.

[0004] To achieve the above objectives, the present invention provides a copper extrusion forming apparatus, comprising: an upper die mechanism, a lower die base, a forming die, an upper die insert, a forming insert, an exhaust channel, and a buffer component. The upper die mechanism is slidably connected to the lower die base. The forming die and the upper die insert are both disposed on the upper die mechanism, and the forming die penetrates through the upper die insert. The lower die base is provided with a mounting groove located directly below the forming die. The forming insert is disposed within the mounting groove. At least one exhaust channel is provided within the lower die base, and the exhaust channel communicates with the interior of the forming insert. The bottom of the mounting groove is provided with a mounting cavity. The buffer component is disposed within the mounting cavity and communicates with the interior of the forming insert. A connecting rod is slidably connected to the buffer component, and a plug is provided on the connecting rod. The plug is inserted into the exhaust channel.

[0005] As a further description of the above technical solution:

[0006] The buffer component includes an airbag, a cylinder, a first spring, and a second spring. The airbag is connected to the piston rod of the cylinder and is connected to the interior of the molded insert through an air tube. The first spring and the second spring are both sleeved on the cylinder, and the connecting rod is located between the first spring and the second spring.

[0007] As a further description of the above technical solution:

[0008] The cylinder is provided with a mounting box, and the airbag is located inside the mounting box.

[0009] As a further description of the above technical solution:

[0010] The airbag is a rubber airbag.

[0011] As a further description of the above technical solution:

[0012] The exhaust channel is provided with a sealing groove, and the plug is inserted into the sealing groove.

[0013] As a further description of the above technical solution:

[0014] The exhaust channel has a flared exhaust port at one end within the molded insert.

[0015] As a further description of the above technical solution:

[0016] The upper mold mechanism includes an upper mold base, an upper pad, and an upper ejector plate arranged sequentially from top to bottom. The upper mold insert is connected to the upper ejector plate, and the forming male is connected to the upper mold base.

[0017] As a further description of the above technical solution:

[0018] The upper release plate is elastically connected to the upper pad plate by a third spring.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: by setting an exhaust channel and a buffer component in the lower mold base, the gas in the molding insert can be discharged in time to prevent the mold from bursting. Specifically, the gas in the molding insert is discharged into the air bladder through the air pipe. After the air bladder is inflated, it expands and compresses the first spring and the second spring, and causes the cylinder to move down, thereby driving the connecting rod to move down, causing the plug to disengage from the sealing groove. The gas can then be discharged again from the air channel until the extrusion molding is completed. When the upper mold mechanism moves back to its original position, the gas in the air bladder is released back into the molding insert. At the same time, the first spring and the second spring reset, causing the plug to enter the sealing groove and seal the exhaust channel. This allows the gas in the air bladder to enter the molding insert, lifting the molded finished product for easy material collection. Attached Figure Description

[0030] Please see Figure 1-2This invention provides a copper extrusion forming apparatus, comprising: an upper die mechanism 1, a lower die base 2, a forming male 3, an upper die insert 4, a forming insert 5, an exhaust channel 6, and a buffer component 7. The upper die mechanism 1 is slidably connected to the lower die base 2. The forming male 3 and the upper die insert 4 are both disposed on the upper die mechanism 1, and the forming male 3 penetrates the upper die insert 4. The lower die base 2 is provided with a mounting groove 8, which is located directly below the forming male 3. The forming insert 5 is disposed in the mounting groove 8. At least one exhaust channel 6 is provided in the lower die base 2, and the exhaust channel 6 communicates with the interior of the forming insert 5. The bottom of the mounting groove 8 is provided with a mounting cavity 9. The buffer component 7 is disposed in the mounting cavity 9 and communicates with the interior of the forming insert 5. A connecting rod 10 is slidably connected to the buffer component 7, and a plug 11 is provided on the connecting rod 10. The plug 11 is inserted into the exhaust channel 6.

[0031] The buffer component 7 includes an air bladder 71, a cylinder 72, a first spring 73, and a second spring 74. The air bladder 71 is connected to the piston rod of the cylinder 72 and is connected to the interior of the molding insert 5 via an air tube. The first spring 73 and the second spring 74 are both sleeved on the cylinder 72, and the connecting rod 10 is located between the first spring 73 and the second spring 74. This buffering effect reduces the instantaneous pressure on the product during extrusion molding and the internal air pressure of the molding insert.

[0032] The cylinder 72 is provided with a mounting box 12, and the airbag 71 is located inside the mounting box 12. The mounting box is made of elastic material to facilitate the placement of the airbag.

[0033] The airbag is a rubber airbag 71.

[0034] A sealing groove 13 is provided in the exhaust channel, and the plug is inserted into the sealing groove 13. When the airbag is not fully inflated, the plug seals the exhaust channel, preventing gas from flowing out and causing the airbag to fail and lose its buffering effect. When the airbag is fully inflated, the first spring is compressed, which moves the connecting rod downward, thereby causing the plug to disengage from the sealing groove, allowing gas to flow out of the exhaust channel and achieving the exhaust effect. When the airbag is deflated, the first and second springs reset, and the plug can block the exhaust channel again, increasing the air pressure and causing the gas in the airbag to propel the product, facilitating material collection.

[0035] The exhaust channel 6 has a flared exhaust port at one end within the molded insert 5.

[0036] The upper mold mechanism 1 includes an upper mold base 14, an upper pad 15, and an upper ejector plate 16 arranged sequentially from top to bottom. The upper mold insert 4 is connected to the upper ejector plate 16, and the forming male 3 is connected to the upper mold base 14.

[0037] The upper release plate 16 is elastically connected to the upper pad plate 15 by a third spring 17.

[0038] Working principle: By setting an exhaust channel and buffer components in the lower mold base, the gas in the molding insert can be discharged in time to prevent the mold from bursting. Specifically, the gas in the molding insert is discharged into the air bladder through the air pipe. After the air bladder is inflated, it expands and compresses the first and second springs, causing the cylinder to move down, thereby driving the connecting rod down and causing the plug to disengage from the sealing groove. The gas can then be discharged again through the air channel until the extrusion molding is completed. When the upper mold mechanism moves back to its original position, the gas in the air bladder is released back into the molding insert. At the same time, the first and second springs reset, causing the plug to enter the sealing groove and seal the exhaust channel. This allows the gas in the air bladder to enter the molding insert, lifting the molded product for easy material collection.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
