Description

Technical Field

[0001] This utility model relates to the field of mechanical design and manufacturing technology, and in particular to a mold fixing device. Background Technology

[0002] Bridge cranes are lifting equipment that spans across workshops, warehouses, and material yards for material handling. Because their ends rest on tall concrete pillars or metal supports, they resemble bridges. The bridge frame of a bridge crane runs longitudinally along rails laid on elevated structures on both sides, making full use of the space beneath the bridge frame for material handling without being obstructed by ground equipment. It is the most widely used and numerous type of lifting machinery.

[0003] Large molds are typically lifted and transported using bridge cranes, secured with chains. While this method offers some flexibility and eliminates the need for consistent relative positioning, the chains' inherent instability makes them highly vulnerable to movement. As the mold moves, the chains sway, causing the mold to wobble as well. This can lead to chain breakage or damage to other equipment or personnel within the factory, posing a significant risk to life and property and jeopardizing production safety. Furthermore, while the chains are directly hooked to the molds, varying hook positions, tensions, and angles can cause misalignment when the mold is lifted off the ground, preventing horizontal lifting and lowering. Returning large molds to the ground or loading them into injection molding or die-casting machines requires manual, precise adjustment of the mold angle to ensure proper alignment with the appropriate equipment notch. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. When hoisting and transporting molds, chains are used for fixing them, but the chains are extremely unstable. When the mold moves, the chains shake, causing the mold to shake as well. Large molds may break the chains or shake onto other equipment or people in the factory, causing damage to the mold or other equipment and endangering people's lives and property. This is very dangerous and detrimental to production safety. It requires manual and precise adjustment of the mold angle and alignment with the equipment notch to fit the mold. This invention provides a mold fixing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mold fixing device, including a crane, the crane including a main body, a displacement machine fixedly connected to the lower part of the main body, the displacement machine including an upper slider, a gear rotatably connected to the inner surface of the upper slider, a lower slider rotatably connected to the outer surface of the gear, a telescopic mechanism fixedly connected to the lower surface of the lower slider, the telescopic mechanism including a hydraulic tank, and a hydraulic rod slidably connected to the lower part of the hydraulic tank.

[0006] In a preferred embodiment, a ceiling is fixedly connected to the lower part of the hydraulic rod, the ceiling includes a hanging frame, a limit bolt is rotatably connected to the inner surface of the hanging frame, and a fixing block is fixedly connected to the upper part of the hanging frame.

[0007] In a preferred embodiment, a double-ended bolt is rotatably connected to the inner surface of the fixing block, and a lifting ring is slidably connected to the outer surface of the double-ended bolt.

[0008] In a preferred embodiment, the inner surface of the hanging frame is provided with a threaded hole that matches the outer surface of the limiting bolt, and the inner surface of the fixing block is provided with a threaded hole that matches the double-ended bolt.

[0009] In a preferred embodiment, an I-shaped rail is slidably connected to the inner surface of the main body, and a motor is fixedly connected to the side of the main body.

[0010] In a preferred embodiment, a protrusion is fixedly connected to the side of the main body, a roller is rotatably connected to the inner surface of the protrusion, and a wheel is rotatably connected to the outer surface of the roller.

[0011] In a preferred embodiment, both the lower surface of the upper slider and the upper surface of the lower slider are provided with tooth grooves that are adapted to the outer surface of the gear.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention utilizes existing bridge-type starter track for lateral movement, replacing chains with telescopic mechanisms. This eliminates the impact of chain swaying, resulting in a more stable structure. Lifting large molds does not cause significant tilting, ensuring smoother mold transport. Through gears and upper and lower sliders, the displacement mechanism moves longitudinally with relatively small movements, reducing the impact of removing flexible chains. The added lifting frame further reduces mold swaying, ensuring mold stability. It also reduces the need for long-term manual calibration of external devices to match the mold, avoiding the risk of mold colliding with other devices or falling and endangering personal safety, thus improving production safety.

[0019] 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.

[0020] Example 1 like Figures 1-5 As shown, this utility model provides a technical solution: a mold fixing device, including a crane 1, the crane 1 including a main body 11, a displacement machine 2 fixedly connected to the lower part of the main body 11, the displacement machine 2 including an upper slider 21, a gear 23 rotatably connected to the inner surface of the upper slider 21, a lower slider 22 rotatably connected to the outer surface of the gear 23, a telescopic machine 3 fixedly connected to the lower surface of the lower slider 22, the telescopic machine 3 including a hydraulic tank 31, a hydraulic rod 32 slidably connected to the lower part of the hydraulic tank 31.

[0021] In this embodiment, the crane 1 is connected to the displacement machine 2, and the displacement machine 2 is connected to the telescopic machine 3. This eliminates the need for the chain used during hoisting and handling to be fixedly connected to the mold. Although it is not as flexible as the chain to some extent, it ensures the stability of the device when the mold moves, ensures the smooth lifting of the mold, and prevents it from shaking and hitting other equipment or people in the factory. The mold or other equipment will not be damaged, and people's lives and property will not be endangered, thus reducing danger and promoting production safety.

[0022] Example 2 like Figures 1-5As shown, a ceiling 4 is fixedly connected to the lower part of the hydraulic rod 32. The ceiling 4 includes a hanging frame 41. A limit bolt 42 is rotatably connected to the inner surface of the hanging frame 41. A fixing block 43 is fixedly connected to the upper part of the hanging frame 41. A double-ended bolt 45 is rotatably connected to the inner surface of the fixing block 43. A lifting ring 44 is slidably connected to the outer surface of the double-ended bolt 45. A threaded hole adapted to the outer surface of the limit bolt 42 is opened on the inner surface of the hanging frame 41. A threaded hole adapted to the double-ended bolt 45 is opened on the inner surface of the fixing block 43. An I-shaped rail 5 is slidably connected to the inner surface of the main body 11. A motor 12 is fixedly connected to the side of the main body 11. A protrusion 13 is fixedly connected to the side of the main body 11. A roller 15 is rotatably connected to the inner surface of the protrusion 13. A roller 14 is rotatably connected to the outer surface of the roller 15. The lower surface of the upper slider 21 and the upper surface of the lower slider 22 are both provided with tooth grooves adapted to the outer surface of the gear 23.

[0023] In this embodiment, because the drilling positions on the surface of large molds are not fixed, their positions on different mold surfaces are roughly different and not necessarily completely consistent. Moreover, different mold sizes may cause the drilling positions on their surfaces to be different. The end of the lifting ring 44 is threaded to the mold. By using the cooperation of the lifting frame 41 and the fixing block 43, a certain space is reserved for installing the lifting ring 44, ensuring that the lifting frame 41 can be adapted to different molds. The double-ended bolt 45 is threaded to the inside of the fixing block 43, which restricts the position of the mold to a certain extent. Then, by using the cooperation of the limiting bolt 42 and the lifting frame 41, the limiting bolt 42 is first threaded to the lifting frame 41. Continue to rotate the limiting bolt 42 until it is locked in the slot on the side of the mold, ensuring that the mold is fixed and there is no angular displacement, achieving horizontal lifting. When the mold is placed back on the ground and loaded into the injection molding machine or die casting machine, there is no need for manual fine adjustment of the mold angle.

[0024] Working principle: like Figures 1-5 As shown, start motor 12, which drives roller 14 to move on I-beam rail 5, and then drives telescopic machine 3 to descend. Hydraulic rod 32 descends. According to the mold position, start displacement machine 2 to move appropriately, connect lifting ring 44 to the surface of mold, and then fix lifting ring 44 with double-headed bolt 45. Push limit bolt 42 to the groove on the side of mold through lifting frame 41, start hydraulic rod 32 to rise, move crane 1 to a suitable position, and then start hydraulic rod 32 to descend. Lower the mold, remove limit bolt 42 and lifting ring 44, start hydraulic rod 32 to rise, and start crane 1 to move to an open area or the next mold.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
