Description

Technical Field

[0001] This utility model relates to the field of mold processing equipment technology, specifically to a mold external hardware feeding device. Background Technology

[0002] In the mold processing industry (such as metal stamping and plastic insert injection molding), metal parts (metal rods, metal sheets) must be accurately fed into the mold cavity or positioning hole to complete subsequent molding processes. Current metal part feeding methods mostly rely on manual labor, which has the following technical drawbacks, restricting production efficiency and processing accuracy:

[0003] Manual feeding is inefficient: Each person manually grabs and feeds the hardware parts into the mold, limiting the number of feedings per hour and resulting in significant waste of human resources. Hardware compatibility is poor, and switching is cumbersome: the limiting components of the feeding device are mostly of fixed size, only compatible with a single specification of hardware part. Changing specifications requires disassembling and replacing the limiting blocks, resulting in long switching times and high production line downtime costs. Utility Model Content

[0004] The purpose of this utility model is to provide a mold external hardware feeding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold external hardware feeding device, comprising a control plate and a mounting frame. A first threaded rod is rotatably connected to the upper part of the control plate, and a lifting plate is threadedly connected to the outer side of the first threaded rod. Three sets of first guide rods are slidably connected inside the lifting plate. The lower part of the first guide rod is fixedly connected to the upper part of the control plate. Four sets of connecting slots are opened inside the control plate and the lifting plate. Limiting rods are slidably connected inside the connecting slots. Clamping plates are slidably connected between the limiting rods on the same side. A falling slot is opened in the middle of the lifting plate. A bending frame is fixedly connected to one side of the lifting plate. A first hydraulic cylinder is fixedly connected to one side of the bending frame. The output end of the first hydraulic cylinder penetrates the bending frame and is fixedly connected to a pushing frame. The pushing frame is close to the lower part of the lifting plate. An outer pushing plate is fixedly connected to the other side of the pushing frame.

[0006] Preferably, a limiting piece is fixedly connected to the upper part of the limiting rod.

[0007] Preferably, baffles are fixedly connected to both sides of the upper part of the lifting plate, and the baffles are disposed on both sides of the lower drop chute.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model automatically pushes metal plates into the mold by relying on the coordinated action of the first hydraulic cylinder driving the push frame and the inner and outer push plates, eliminating the need for manual grabbing of hardware parts and repeated position adjustment; at the same time, through the adjustment of the distance between the lifting plate and the control plate and the limiting effect of the clamping plate, the metal rods are fed in a single quantity, avoiding manual sorting of multiple stacked metal rods. The entire process requires no manual intervention, significantly reducing labor costs, improving the overall feeding rhythm, and adapting to the needs of large-scale continuous production.

[0014] 2. This utility model also allows two sets of mounting plates to slide in opposite directions by rotating the second threaded rod, which in turn drives the limiting rod and clamping plate to adjust the distance synchronously, thereby adapting to metal rods of different sizes; the inner pushing plate, which is slidably connected inside the outer pushing plate, can flexibly adjust the pushing length to adapt to metal plates of different specifications by cooperating with the guide of the limiting block and the limiting groove; there is no need to frequently disassemble and replace the limiting components, and the specification switching can be completed by simply rotating or pushing the handwheel, reducing the downtime of the production line and improving the equipment's adaptability to diverse processing needs.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: an external hardware feeding device for molds, including a control plate 1 and a mounting frame 24. A first threaded rod 2 is rotatably connected to the upper part of the control plate 1 via a deep groove ball bearing. An adjusting handwheel is welded to the top of the first threaded rod 2 for easy manual rotation. A lifting plate 4 is threadedly connected to the outer side of the first threaded rod 2. Three sets of first guide rods 3 are slidably connected inside the lifting plate 4. The lower part of the first guide rods 3 is fixedly connected to the upper part of the control plate 1 by welding. Rotating the first threaded rod 2 drives the lifting plate 4 to rise and fall along the first guide rods 3. Adjusting the distance between the lifting plate 4 and the control plate 1 allows only one metal rod to pass through. The control plate 1 and the lifting plate 4 are internally... Four sets of connecting slots 8 are provided at corresponding positions. Limiting rods 9 are slidably connected inside the connecting slots 8. Clamping plates 11 are slidably connected between the limiting rods 9 on the same side. A falling slot 12 is provided in the middle of the lifting plate 4. By adjusting the height of the lifting plate 4, the distance between the lifting plate 4 and the control plate 1 is only slightly larger than the diameter of the metal rod, ensuring that only one metal rod falls at a time. A bent frame 15 is fixedly connected to one side of the lifting plate 4 by welding. A first hydraulic cylinder 16 is fixedly connected to one side of the bent frame 15 by flange bolts. After the output end of the first hydraulic cylinder 16 penetrates the bent frame 15, a push frame 17 is fixedly connected by bolts. An outer push plate 18 is fixedly connected to the other side of the push frame 17 by welding.

[0023] The upper part of the limiting rod 9 is fixedly connected to the limiting piece 10 by welding to prevent the clamping plate 11 from disengaging from the limiting rod 9;

[0024] Baffles 13 are fixedly connected to the upper two sides of the lifting plate 4 by welding. The baffles 13 are set on both sides of the lower drop trough 12 to prevent the metal rod from rolling off the side.

[0025] The lower part of the control board 1 is fixedly connected to the connecting frame 5 by welding. The second threaded rod 6 is rotatably connected to the inside of the connecting frame 5 by a deep groove ball bearing. The threads at both ends are turned in opposite directions. The outer side of the second threaded rod 6 is threaded to two sets of symmetrical mounting plates 7. One end of the second threaded rod 6 extends out of the connecting frame 5 and is welded with a handwheel to facilitate adjustment of the spacing between the mounting plates 7. The lower part of the limit rod 9 on the same side is fixedly connected to the upper part of the mounting plate 7 by welding. Rotating the second threaded rod 6 can drive the two sets of mounting plates 7 to slide in opposite directions. The mounting plate 7 drives the limit rod 9 and the clamping plate 11 to move synchronously. Adjusting the spacing between the two sets of clamping plates 11 can accommodate metal rods of different diameters.

[0026] The control board 1 has inclined platforms 14 fixedly connected to the two sides of the middle section by welding. During the pushing process of the metal plate, the two side edges contact the inclined platforms 14 and automatically move towards the center of the control board 1 under the guidance of the inclined platforms 14 to achieve centering and avoid pushing deviation.

[0027] An inner push plate 19 is slidably connected inside the outer push plate 18. Restriction grooves 20 are provided on both sides inside the outer push plate 18. Restriction blocks 21 are fixedly connected to the upper two sides of the inner push plate 19 by welding. The restriction blocks 21 are slidably connected inside the restriction grooves 20 to prevent the inner push plate 19 from coming off the outer push plate 18. According to the distance between the control plate 1 and the lifting plate 4, the inner push plate 19 contacts the control plate 1 under the action of gravity, thereby increasing the contact area between the push plate and the metal rod.

[0028] Two sets of second hydraulic cylinders 23 are fixedly connected to the upper part of the mounting frame 24 by flange bolts. The output end of the second hydraulic cylinder 23 penetrates the mounting frame 24 and is fixedly connected to a bent plate 22 by bolts. The lower part of the bent plate 22 is fixedly connected to the upper part of the control plate 1 by welding. The extension and retraction of the second hydraulic cylinder 23 can drive the control plate 1 to rise and fall as a whole. When the mold is closed, it rises to avoid obstruction, and when feeding, it falls to reset. A fixed mold 25 is fixedly connected to one side of the inside of the mounting frame 24 by bolts. Four sets of second guide rods 27 are fixedly connected to each other inside the mounting frame 24 by welding. A sliding mold 28 is slidably connected to the outside of the second guide rods 27. Insertion slots 26 for matching hardware are opened at corresponding positions of the fixed mold 25 and the sliding mold 28.

[0029] Working principle: When using this utility model: Based on the diameter of the metal rod, rotate the second threaded rod 6 handwheel to drive the two sets of mounting plates 7 to slide in opposite directions; the mounting plate 7 drives the limit rod 9 and the clamping plate 11 to move, so that the distance between the two sets of clamping plates 11 is slightly larger than the diameter of the metal rod, thus completing the metal rod limiting and matching; rotate the first threaded rod 2 handwheel to drive the lifting plate 4 to rise and fall along the first guide rod 3, so that the distance between the lifting plate 4 and the control plate 1 is slightly larger than the diameter of the metal rod, allowing only one metal rod to pass through, thus completing the quantitative feeding adjustment;

[0030] Metal rods are poured in batches into the lower groove 12 of the lifting plate 4. The metal rods move downward under the action of gravity. Since the gap between the lifting plate 4 and the control plate 1 only allows one metal rod to pass through, only one metal rod falls into the channel between the control plate 1 and the lifting plate 4 at a time. The metal rod rolls along the channel to the middle of the control plate 1 and is limited by the clamps 11 on both sides.

[0031] Start the first hydraulic cylinder 16; the output end of the first hydraulic cylinder 16 pushes the push frame 17, the outer push plate 18 and the inner push plate 19 to move synchronously toward the mold;

[0032] The metal rod moves under the action of the push plate, and the two sides of the edge contact the inclined platform 14 of the control plate 1. Under the guidance of the inclined platform 14, it automatically moves towards the center to achieve centering positioning. The push plate continues to push the metal plate until the metal rod is completely inserted into the insertion slot 26 of the fixed mold 25, completing the feeding. The output end of the first hydraulic cylinder 16 retracts, and the push plate resets.

[0033] After feeding is completed, the second hydraulic cylinder 23 is activated, and the output end retracts, causing the bending plate 22 and the control plate 1 to rise as a whole, so that the control plate 1, the lifting plate 4 and other feeding components are away from the mold area; the sliding mold 28 moves along the second guide rod 27 to the fixed mold 25, and the mold is closed to complete the hardware processing; after processing is completed, the sliding mold 28 is reset; the output end of the second hydraulic cylinder 23 extends, causing the control plate 1 to descend to the initial position, ready for the next feeding.
