Description

Technical Field

[0001] This utility model belongs to the field of edge cutting die technology, and specifically relates to a pressing mechanism for an edge cutting die. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the object's shape by changing the physical state of the material being molded. It is a tool that, under the action of external force, transforms a blank into a part with a specific shape and size. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics, and other products. An edge-trimming die is a stamping die that uses a die to trim the edges of a workpiece, giving it a certain height, diameter, and shape. Edge-trimming dies are mainly used to trim the edges of stretched parts, making the end face flat and aesthetically pleasing, facilitating subsequent assembly. Edge-trimming dies are widely used in machinery manufacturing, automotive parts production, beverage bottle processing, fastener mold matching, and other fields. This utility model specifically relates to an edge-trimming die pressing mechanism.

[0003] Currently, most existing edge-cutting die pressing mechanisms do not have the function of pressing and cleaning the burrs to be cut during edge cutting. As a result, during the loading and unloading process, the uncleaned burrs fall onto the die, affecting the stability of the die and thus affecting the edge cutting effect. To address this, we propose a pressing mechanism for edge-cutting dies. Utility Model Content

[0004] The purpose of this utility model is to provide a pressing mechanism for an edge-cutting die, so as to solve the problem that most of the aforementioned background technologies do not have the function of pressing and cleaning the burrs to be cut, which causes the burrs not to be cleaned to fall onto the die during the loading and unloading process, affecting the stability of the die and thus affecting the cutting effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressing mechanism for a side-cutting mold, comprising a base and a cutting plate, a support frame fixedly welded to one side of the top of the base, a hydraulic rod mounted at one end of the top of the support frame, a lifting plate fixedly installed at the bottom of the hydraulic rod, and cutting blades fixedly installed around the bottom of the lifting plate. A shrink sleeve is movably connected to the outer side of the cutting blade via a movable connecting seat. A telescopic rod extending to the outside is slidably provided at the bottom of the inner side of the shrink sleeve. A pressure plate is movably connected to the bottom of the telescopic rod via a movable connecting seat. An ejection spring is provided inside the shrink sleeve, and the two ends of the ejection spring are fixedly connected to the inner top wall of the shrink sleeve and the top of the telescopic rod, respectively.

[0006] Preferably, a convex pad is provided at the outer bottom end of the cutter, and the convex pad is fixedly connected to the cutter by adhesive bonding, with one side of the convex pad contacting the outer bottom end of the shrink sleeve.

[0007] Preferably, the bottom of the pressure plate is provided with an anti-slip pad, which is fixedly installed on the bottom of the pressure plate by adhesive bonding.

[0008] Preferably, a spring cylinder is fixedly installed at the bottom center of the lifting plate, and a telescopic block extending to the outer side of the bottom of the spring cylinder is slidably provided inside the bottom end of the spring cylinder. A pressing mold is fixedly installed at the bottom of the telescopic block, and a buffer spring is provided inside the spring cylinder.

[0009] Preferably, the inner walls on both sides of the spring cylinder and the retractable sleeve are provided with limiting grooves, and the top sides of the telescopic block and the telescopic rod are provided with limiting blocks. The telescopic block and the telescopic rod are connected to the spring cylinder and the retractable sleeve by limiting grooves and limiting blocks respectively.

[0010] Preferably, the base has a mold body fixed at the top center position, and the mold body is located directly below the pressing mold.

[0011] Preferably, guide rods are provided around the top of the base, and the two ends of the guide rods are fixedly connected to the top wall of the support frame and the top of the base by welding.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting a movable shrink sleeve on the outside of the cutter, along with a telescopic rod, pressure plate, and anti-slip pad, the burrs can be pressed tightly before they are cut off. After the burrs are cut off, the return force of the ejector spring pushes the telescopic rod outward, thereby driving the shrink sleeve and telescopic rod to flip. This achieves the function of pushing the cut-off burrs away from the mold body, thus cleaning up the cut-off burrs.

[0013] 2. By setting a convex pad at the bottom outer side of the cutter, it is ensured that the shrink sleeve and the telescopic rod can maintain a certain tilt angle under normal conditions. This allows the return force of the ejector spring to be used when the pressed burrs are cut off, so that the telescopic rod extends outward and resets at the same time, the shrink sleeve and the telescopic rod can be flipped at a certain angle, thus ensuring the stability of cleaning the cut burrs.

[0016] 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.

[0017] Please see Figure 1-4 This utility model provides a material pressing mechanism for a side-cutting die: it includes a base 1, a cutter 7, and a pressure plate 19. A support frame 3 is fixedly welded to one side of the top of the base 1. A hydraulic rod 4 is mounted on one end of the top of the support frame 3. A lifting plate 5 is fixedly installed at the bottom of the hydraulic rod 4. Cutters 7 are fixedly installed around the bottom of the lifting plate 5. A shrink sleeve 15 is movably connected to the outer side of the cutter 7 through a movable connecting seat 16. A telescopic rod 17 extending to the outside is slidably provided at the bottom of the inner side of the shrink sleeve 15. The bottom of the telescopic rod 17 is movably connected to the outer side through the movable connecting seat 16. There is a pressure plate 19, and an ejector spring 18 is installed inside the shrink sleeve 15. The two ends of the ejector spring 18 are fixedly connected to the inner top wall of the shrink sleeve 15 and the top of the telescopic rod 17, respectively. By using the ejector spring 18 to push the telescopic rod 17 to extend outward, in conjunction with the movable connecting seat 16, the burrs pressed by the pressure plate can be cut off. Under the action of the ejector spring 18, the telescopic rod 17 can be pushed to extend, and the shrink sleeve 15 and the telescopic rod 17 can be rotated to a certain extent, so that the pressure plate 19 pushes the burrs away, thereby achieving the purpose of cleaning the cut-off burrs.

[0018] Specifically, a convex pad 14 is provided at the bottom outer side of the cutter 7. The convex pad 14 is fixedly connected to the cutter 7 by gluing. One side of the convex pad 14 is in contact with the bottom outer side of the shrink sleeve 15.

[0019] Specifically, an anti-slip pad 20 is provided at the bottom of the pressure plate 19, and the anti-slip pad 20 is fixedly installed at the bottom of the pressure plate 19 by gluing.

[0020] Specifically, a spring cylinder 8 is fixedly installed at the bottom center of the lifting plate 5. A telescopic block 9 extending to the outer side of its bottom is slidably provided inside the bottom of the spring cylinder 8. A pressing mold 10 is fixedly installed at the bottom of the telescopic block 9. A buffer spring 11 is provided inside the spring cylinder 8.

[0021] Specifically, the inner walls of both sides of the spring cylinder 8 and the retractable sleeve 15 are provided with limiting grooves 12, and the top sides of the telescopic block 9 and the telescopic rod 17 are provided with limiting blocks 13. The telescopic block 9 and the telescopic rod 17 are connected to the spring cylinder 8 and the retractable sleeve 15 by limiting grooves 12 and limiting blocks 13 respectively.

[0022] Specifically, the top center of the base 1 is fixed with a mold body 2, which is located directly below the pressing mold 10.

[0023] Specifically, guide rods 6 are provided around the top of the base 1. The two ends of the guide rods 6 are fixedly connected to the top wall of the support frame 3 and the top of the base 1 by welding.

[0024] In this embodiment, during use, the material to be cut is placed on the mold body 2. Then, the hydraulic rod 4 is pressed down, causing the lifting plate 5 to descend, placing the pressing mold 10 over the material and applying pressure. Simultaneously, the telescopic block 9 retracts into the spring cylinder 8, working in conjunction with the buffer spring 11 to cushion the impact and ensure the material is compressed. As the lifting plate 5 moves downward under the continuous push of the hydraulic rod 4, the anti-slip pad 20 gradually contacts and presses the rough edges of the material. The resulting force pushes the pressure plate 19, causing the telescopic rod 17 to retract into the shrink sleeve 15 and compress the ejector spring 18. Since the rough edges are connected to the material at this point, they cannot be pushed away from the top of the mold body 2. After the pressure plate 19 uses the anti-slip pad 20 to press the rough edges, the cutter 7 continues to move downward with the lifting plate 5. The blade gradually contacts the junction of the burr and the forming material and cuts it to achieve the purpose of trimming. After being cut, the burr separates from the forming material, and under the action of the convex pad 14, the shrink sleeve 15 and the telescopic rod 17 have a certain tilt angle. Under the action of the ejector spring 18, the telescopic rod 17 and the pressure plate 19 and anti-slip pad 20 connected to its bottom through the movable connecting seat 16 are pushed outward. Due to the tilt angle, the pressure plate 19 and the anti-slip pad 20 gradually move away from the cutter 7, thereby achieving the purpose of pushing away the cut burr and detaching it from the mold body 2. This avoids the burr from sticking on the mold body 2 during loading and unloading, which would affect the stability of the forming material. This design effectively achieves the function of cleaning the cut burr and ensures the stability of the forming material during trimming, thereby ensuring the stability of the trimming effect.
