Description

Technical Field

[0001] This utility model relates to the field of feeder hole mold technology, and more specifically to feeder hole mold for middle plates. Background Technology

[0002] Currently, when processing feeder hole frames, bending operations are usually required. The bending operation is achieved by using the two bending arms of the bending die to rotate and create a certain tilt angle, which squeezes and bends the two sides of the feeder hole frame. However, during long-term operation, the contact surface between the bending arms and the feeder hole frame will wear, which will affect the bending effect and reduce its service life, and needs to be improved. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a middle plate feeder hole mold to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a board feeder hole mold, including a mold base, two fixed frames symmetrically fixedly installed on the top of the mold base, baffles fixedly installed on the front and rear sides of the fixed frames by bolts, a bending swing arm between the two fixed frames, the number of bending swing arms is two, a support shaft is rotatably installed inside one side of the bottom end of the two bending swing arms, the two ends of the support shaft are fixedly connected to the two baffles, a U-shaped feeder hole frame is provided above the interior between the two bending swing arms, an upper pad block overlaps the middle of the bottom of the U-shaped feeder hole frame, the bottom of the upper pad block overlaps the inner wall between the two bending swing arms, and a wear-resistant block is fixedly connected to the top of each of the two bending swing arms by bolts, one side of the wear-resistant block overlaps the upper side wall of the U-shaped feeder hole frame.

[0005] Furthermore, an elastic pad is provided in the middle of the top of the mold base, and a lower pad block is fixedly connected to the top of the elastic pad block. The lower pad block is located inside the two bending swing arms and has chamfers on both sides of the top of the lower pad block.

[0006] Furthermore, an O-shaped opening is provided on the upper part of one side of each of the two fixed frames, and a limiting rod is provided inside the O-shaped opening. One end of the limiting rod is fixedly installed inside the upper part of one side of the bending swing arm.

[0007] Furthermore, support frames are fixedly connected to both sides of the top of the mold base, a support plate is fixedly connected to the top of the support frame, a hydraulic rod is fixedly installed in the middle of the bottom of the support plate, and a spherical pressure block is fixedly connected to the telescopic end of the hydraulic rod.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] 1. This utility model, by employing a hydraulic rod and a spherical pressure block, facilitates the application of pressure to the bottom and upper pad of the U-shaped feeder hole frame. Simultaneously, the upper pad drives the bottom ends of the two bending swing arms to rotate on the support shaft. At this time, the two bending swing arms tilt inward, causing the wear-resistant block to press against both sides of the U-shaped feeder hole frame, thus performing a bending operation on both sides of the U-shaped feeder hole frame. The use of the moving wear-resistant block reduces wear caused by the pressing contact between the bending swing arms and the feeder hole frame. Furthermore, since the bending swing arms and the wear-resistant block are connected by bolts, it is easy to replace the wear-resistant block, thereby improving the service life of this mold.

Detailed Implementation

[0015] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The middle plate feeder hole mold involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example 1:

[0017] like Figure 1-3As shown, the board feeder hole mold includes a mold base 1, on which two fixing brackets 2 are symmetrically fixedly installed on the top. Baffles 3 are bolted to the front and rear sides of the fixing brackets 2. Two bending swing arms 9 are provided between the two fixing brackets 2. A support shaft 10 is rotatably mounted inside one side of the bottom of each of the two bending swing arms 9. The two ends of the support shaft 10 are fixedly connected to the two baffles 3. A U-shaped feeder hole frame 8 is provided above the interior of the space between the two bending swing arms 9. An upper pad 14 overlaps the middle of the bottom of the U-shaped feeder hole frame 8. The bottom of the pad 14 overlaps the inner wall between the two bent swing arms 9. Both the upper and lower surfaces of the upper pad 14 are arc-shaped. The tops of the two bent swing arms 9 are fixedly connected to wear-resistant blocks 11 by bolts. One side of the wear-resistant block 11 overlaps the upper side wall of the U-shaped feeder hole frame 8. Support frames 4 are fixedly connected to both sides of the top of the mold base 1. Support plates 5 are fixedly connected to the top of the support frames 4. A hydraulic rod 6 is fixedly installed in the middle of the bottom of the support plate 5. A spherical pressure block 7 is fixedly connected to the telescopic end of the hydraulic rod 6. The spherical pressure block 7 is located directly above the U-shaped feeder hole frame 8.

[0018] In this embodiment, the support frame 4 and support plate 5 facilitate the support of the hydraulic rod 6. The hydraulic rod 6 facilitates the vertical movement of the spherical pressure block 7. The spherical pressure block 7 applies pressure to the bottom and upper pad 14 of the U-shaped feed hole frame 8 and transmits the pressure to the two bending swing arms 9. At this time, the two arms can rotate on the support shaft 10 and tilt inward. Simultaneously, the wear-resistant block 11 is driven to press the two sides of the U-shaped feed hole frame 8, which facilitates the bending operation on both sides of the U-shaped feed hole frame 8. The use of the moving wear-resistant block 11 can reduce the wear caused by the pressing contact between the bending swing arms 9 and the U-shaped feed hole frame 8. At the same time, since the bending swing arms 9 and the wear-resistant block 11 are connected by bolts, it is easy to replace the wear-resistant block 11, thereby improving the service life of the mold.

[0019] Example 2:

[0020] like Figure 1-3 As shown, an elastic pad 16 is provided in the middle of the top of the mold base 1. A lower pad 15 is fixedly connected to the top of the elastic pad 16. The lower pad 15 is located inside the two bending swing arms 9. Chamfers are provided on both sides of the top of the lower pad 15. An O-shaped opening 13 is provided on the top of one side of each of the two fixing brackets 2. A limiting rod 12 is provided inside the O-shaped opening 13. One end of the limiting rod 12 is fixedly installed inside the upper side of one side of the bending swing arm 9.

[0021] In this embodiment, when the two bending swing arms 9 are tilted, the lower pad 15 is pressed down on the lower part of their inner wall, and the lower pad 15 compresses the elastic soft pad 16, so as to provide elastic support for the lower part of the inner wall of the two bending swing arms 9. At the same time, when the two bending swing arms 9 are tilted, they can drive the limiting rod 12 to move, so that the limiting rod 12 is tilted slightly inside the O-shaped opening 13. The setting of the O-shaped opening 13 facilitates the limiting operation of the limiting rod 12.

[0022] In summary, as Figure 1-3 As shown, in use, the upper pad 14 is first placed on the inner wall between the two bending arms 9, and then the U-shaped feeder hole frame 8 is placed inside between the two bending arms 9, with the bottom of the U-shaped feeder hole frame 8 positioned at the top of the upper pad 14. At this time, the spherical pressure block 7 is moved down to the bottom of the inner wall of the U-shaped feeder hole frame 8 by the telescopic end of the hydraulic rod 6, applying pressure to the bottom of the U-shaped feeder hole frame 8. The bottom of the U-shaped feeder hole frame 8 is pressed down on one side of the inner wall of the two bending arms 9 by the upper pad 14. Due to the pressure of the upper pad 14, the two bending arms 9 are subjected to the pressure of the upper pad 14. At the same time, one side of the bottom end of the two bending swing arms 9 rotates on the outer wall of the support shaft 10, causing the two bending swing arms 9 to tilt inward. The two bending swing arms 9 also drive the wear-resistant block 11 to move, causing the wear-resistant block 11 to press the two sides of the U-shaped feeder hole frame 8 and perform bending operations on the two sides of the U-shaped feeder hole frame 8. When the two bending swing arms 9 are tilted, the lower pad 15 is pressed down on the lower part of its inner wall, and the lower pad 15 compresses the elastic soft pad 16. At the same time, the two bending swing arms 9 drive the limiting rod 12 to move, causing the limiting rod 12 to tilt inside the O-shaped opening 13.
