Description

Technical Field

[0001] This utility model belongs to the field of die forging chain technology, and in particular relates to a side die ejection structure for demolding die forging chains. Background Technology

[0002] Forged chains, also known as forged detachable chains, are chains made through a die forging process. After the forged chain is formed, it needs to be ejected using a built-in ejector rod (or hydraulic ejector device) or by gently tapping it with a soft tool such as a copper rod or pry bar to remove the forging (chain links, pins, etc.) from the die, so as to prevent damage to the surface of the forging.

[0003] Currently, after the forged chain is formed, it needs to be demolded. It is quite laborious for the user to continuously knock the forging with a copper rod. Using a lifting rod to eject it will cause deformation of the forging at the stress point. Therefore, a side mold ejection structure for demolding forged chains is needed. The ejection structure can eject the forging from the cavity, avoiding deformation of the forging at the stress point and affecting subsequent processing, thus ensuring the integrity of the forging surface. Utility Model Content

[0004] The purpose of this invention is to provide a side die ejection structure for demolding forged chains, which can eject the forging from the cavity through the ejection structure, avoid deformation of the forging at the stress position affecting subsequent processing, and ensure the integrity of the forging surface, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A side mold ejection structure for demolding a forged chain includes a cylinder fixedly installed at the bottom of the mold body by bolts. A groove is opened on the front side of the mold body. A lifting plate is provided in the inner cavity of the groove. The output end of the cylinder passes through the mold body and is fixedly connected to the bottom of the lifting plate. Four symmetrical sliding sleeves are provided through the top of the lifting plate. Four symmetrical sliding rods are fixedly connected to the top of the inner cavity of the groove. The sliding rods pass through the sliding sleeves and are slidably connected to the sliding sleeves. A cavity is opened on the top of the mold body. Two symmetrical openings are opened at the bottom of the inner cavity. Two symmetrical push rods are fixedly connected to the top of the lifting plate. The top of the push rod passes through the opening and is fixedly connected to a top block. The top block is adapted to the opening.

[0006] Preferably, the top of the mold body has four symmetrical positioning holes, and handles are fixedly connected to both sides of the mold body.

[0007] Preferably, fixing strips are fixedly connected to both sides of the mold body, and lifting rings are provided on both the front and back of the mold body.

[0008] Preferably, the lifting plate is a rectangular plate, the sliding sleeve is adapted to the sliding rod, and the top rod is in a vertical state.

[0009] Preferably, the handle is U-shaped, and the lifting ring passes through the mold body and is threadedly connected to the mold body.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model activates the cylinder after the forging is formed, causing the lifting plate to move upward. Through the limiting of the sliding sleeve and sliding rod, the lifting plate drives the push rod to move upward, so that the two push rods move upward synchronously to push the forging to the position where the hole needs to be opened. This allows the forging to be ejected from the cavity through the ejection structure, avoiding deformation of the forging at the stress position and affecting subsequent processing, thus ensuring the integrity of the forging surface.

[0012] 2. By designing a handle, this utility model allows for easy movement and transfer of the mold body during turnover, preventing the user's hand from slipping off the surface of the mold body and ensuring the safety of mold body turnover. Attached Figure Description

It includes a cylinder 2 bolted to the bottom of a die body 1. The top of the die body 1 has four symmetrical positioning holes 11. Handles 12 are fixedly connected to both sides of the die body 1. The handles 12 allow for easy movement and transfer of the die body 1 during handling, preventing slippage between the user's hand and the surface of the die body 1, thus ensuring safe handling. The handles 12 are U-shaped. A lifting ring 14 passes through the die body 1 and is threadedly connected to it. The front of the body 1 has a groove 3, and the inner cavity of the groove 3 is provided with a lifting plate 4. The output end of the cylinder 2 passes through the mold body 1 and is fixedly connected to the bottom of the lifting plate 4. Four symmetrical sliding sleeves 5 are provided through the top of the lifting plate 4. Four symmetrical sliding rods 6 are fixedly connected to the top of the inner cavity of the groove 3. The sliding rods 6 pass through the sliding sleeves 5 and are slidably connected to the sliding sleeves 5. The top of the mold body 1 has a cavity 7. The bottom of the inner cavity of the cavity 7 has two symmetrical openings 8. The top of the lifting plate 4 is fixedly connected to two symmetrical push rods 9. The top of the push rods 9 passes through the openings 8 and is fixedly connected to a top block 10. The top block 10 is adapted to the openings 8.

[0023] Example 2:

[0024] Figure 1-4 This invention illustrates a side-die ejection structure for demolding a forged chain according to an embodiment of the present invention. It includes a cylinder 2 fixedly mounted to the bottom of a die body 1 by bolts. Fixing strips 13 are fixedly connected to both sides of the die body 1. Lifting rings 14 are provided on both the front and back of the die body 1. A groove 3 is provided on the front of the die body 1, and a lifting plate 4 is provided within the inner cavity of the groove 3. The output end of the cylinder 2 passes through the die body 1 and is fixedly connected to the bottom of the lifting plate 4. The lifting plate 4 is a rectangular plate. Sliding sleeves 5 are adapted to sliding rods 6. Push rods 9 are in a vertical state. Four symmetrical sliding sleeves 5 are provided through the top of the lifting plate 4. Four symmetrical sliding rods 6 are fixedly connected to the top of the inner cavity of the groove 3. The sliding rods 6 pass through the sliding sleeves 5 and are slidably connected to the sliding sleeves 5. A cavity 7 is provided on the top of the die body 1. Two symmetrical openings 8 are provided at the bottom of the inner cavity of the cavity 7. Two symmetrical push rods 9 are fixedly connected to the top of the lifting plate 4. The top of the push rods 9 passes through the openings 8 and is fixedly connected to a push block 10, which is adapted to the openings 8.

[0025] Working principle: When using this utility model, the user starts the cylinder 2 after the forging is formed, so that the cylinder 2 pushes the lifting plate 4 upward. Through the limiting of the sliding sleeve 5 and the sliding rod 6, the lifting plate 4 drives the push rod 9 upward, so that the two symmetrical push rods 9 drive the two symmetrical push blocks 10 to move upward synchronously. In turn, the push blocks 10 push the forging to the position where the hole needs to be opened. When the forging is separated from the inner cavity of the cavity 7, the force position will be opened during subsequent processing, so as to avoid the deformation of the forging at the force position and affect subsequent processing, thus ensuring the integrity of the forging surface. With the setting of the handle 12, when the mold body 1 is turned over, the mold body 1 can be moved and transported by the handle 12, so as to avoid the user's hand slipping off the surface of the mold body 1 and ensure the safety of the mold body 1 during turnover.

[0026] In summary, this die-forging chain demolding side-die ejection structure works by activating cylinder 2 after the forging is formed, causing lifting plate 4 to move upward. Through the limiting of sliding sleeve 5 and sliding rod 6, lifting plate 4 drives ejector rod 9 to move upward, so that the two ejector rods 9 move upward synchronously to push the forging to the position where the hole needs to be opened. This allows the forging to be ejected from the cavity through the ejection structure, avoiding deformation of the forging at the stress position and affecting subsequent processing, thus ensuring the integrity of the forging surface.
