Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically a transport lifting ring assembly and its injection molding machine. Background Technology

[0002] During the production, transportation, and installation of injection molding machines, lifting eye assemblies are typically used for hoisting or securing them. Traditional lifting eye assemblies usually employ a movable connection method, such as... Figure 3 As shown, its lifting ring uses a hinged structure to allow for free swinging. While this design facilitates angle adjustment during lifting, it has significant drawbacks when transporting or securing the injection molding machine.

[0003] Specifically, when an injection molding machine is secured to a truck frame or ship hull using lifting rings, the machine is prone to displacement during transport due to the jolting, turning, or swaying of the vehicle or vessel, as the lifting rings can swing freely. This displacement can not only lead to collisions between the injection molding machine and the transport carrier, causing equipment damage, but also pose safety hazards if the machine is not securely fixed. Furthermore, the swinging of the lifting rings during hoisting and transfer can cause instability in the injection molding machine's posture, increasing operational difficulty and risk.

[0004] Currently, there is a lack of lifting ring assembly designs on the market that can balance lifting flexibility and transportation stability. Therefore, there is an urgent need for a new type of lifting ring fixing structure to solve the problem of insufficient stability of traditional lifting rings during transportation and fixing, thereby improving the safety and reliability of injection molding machines during lifting and transportation. Utility Model Content

[0005] To address the technical problems in the background art, this utility model discloses a transport lifting ring assembly and its injection molding machine.

[0006] This utility model provides a transport lifting ring assembly, including a lifting ring;

[0007] The lifting ring consists of a fixed part and a connecting part forming an obtuse angle;

[0008] The fixing part is fixedly connected to the body of the injection molding machine by bolts;

[0009] The connecting part extends away from the injection molding machine body and is used to connect ropes.

[0010] Furthermore, the lifting ring is integrally cast.

[0011] Furthermore, the fixing part and the connecting part form an included angle of 135±3°.

[0012] Furthermore, the hardness of the lifting ring is above HRC20.

[0013] Furthermore, the fixing part is provided with fixing holes; a bushing is inserted into the fixing holes; the bolt passes through the bushing and is connected to the frame of the injection molding machine.

[0014] Furthermore, the hardness of the bushing is above HRC20.

[0015] This utility model also provides an injection molding machine, on which a transport lifting ring assembly is installed.

[0016] The beneficial effects of this utility model are:

[0017] In this invention, the fixing part and the connecting part are integrally formed, constituting a fixed overall structure. This avoids the problems caused by the free swing of traditional lifting rings. When the injection molding machine is fixed to the truck frame or cargo ship hull for transportation via the lifting ring, it can effectively prevent the injection molding machine from shifting due to vehicle or ship bumps, turns, or swaying, reducing the risk of collision between the injection molding machine and the transport carrier, avoiding equipment damage, and eliminating safety hazards caused by insecure fixing. Moreover, during the lifting and transfer process, this lifting ring assembly can reduce the swing of the lifting ring, making the injection molding machine's posture more stable, reducing the difficulty and risk of operation, and improving the safety and reliability of the lifting process.

[0018] In this invention, the connecting part extends away from the injection molding machine body, so that the lifting hole on the connecting part is far away from the injection molding machine. When the injection molding machine is being lifted, the lifting rope is also in a position far away from the injection molding machine and will not come into contact with the injection molding machine, thereby avoiding the rope from scratching the injection molding machine or putting pressure on the parts of the injection molding machine and causing damage.

[0019] In this invention, the connecting part of the lifting ring rotates to the upper side during hoisting and to the lower side during transportation. Therefore, the connection between the rope and the lifting ring is not obstructed by the bolts, resulting in a larger operating space. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] Example 1:

[0027] like Figure 1 and Figure 2 As shown, this utility model discloses a transport lifting ring assembly, including a lifting ring 1. The lifting ring 1 is composed of a fixing part 11 and a connecting part 12 forming an obtuse angle. The fixing part 11 has a fixing hole 13, through which a bolt 2 passes and is fixedly connected to the body of the injection molding machine. The connecting part 12 has a lifting hole 14 for connecting ropes, or for lifting the injection molding machine, or for fixing the injection molding machine to the body of a truck or to the hull of a cargo ship.

[0028] The fixing part 11 and the connecting part 12 form an angle of 135±3°. With this arrangement, when the injection molding machine is fixed on a truck or cargo ship, the rope and the connecting part 12 are in a coplanar position. The tension between the rope and the connecting part 12 will not generate a component force in other directions, thereby making the connection between the rope and the connecting part 12 more stable and the positional stability of the injection molding machine during transportation more stable.

[0029] The lifting ring 1 is integrally cast, which results in a higher precision in the included angle between the fixing part 11 and the connecting part 12 compared to the traditional method of bending steel plates.

[0030] A bushing 3 is inserted into the fixing hole 13, and the bolt 2 passes through the bushing 3 to be fixedly connected to the injection molding machine body. The advantages of the bushing 3 are as follows: 1. Due to repeated stress during installation, disassembly, and long-term use, the bolt 2 may wear down the fixing hole 13. The bushing 3 adds a layer of protection between the fixing hole 13 and the bolt 2, reducing the direct friction and compression of the inner wall of the fixing hole 13 by the bolt 2, thereby extending the service life of the fixing hole 13 and thus extending the service life of the lifting ring 1; 2. The bushing 3 provides stable support, ensuring the stability of the connection between the bolt 2 and the lifting ring 1, so that the lifting ring 1 can be more reliably fixed to the injection molding machine body, avoiding displacement or shaking of the lifting ring 1 during lifting or transportation due to loose connection, thus improving the safety and reliability of the injection molding machine during lifting and transportation; 3. If the bushing 3 wears or is damaged due to long-term use or other reasons, the bushing 3 can be replaced separately without replacing the entire lifting ring 1, which not only reduces maintenance costs but also improves maintenance efficiency.

[0031] To improve the stability and extend the service life of the lifting eye assembly, the strength of both the lifting eye 1 and the bushing 3 is above HRC20. In this embodiment, both the lifting eye 1 and the bushing 3 are made of Q355 steel. This not only improves the hardness of the lifting eye 1 and the bushing 3, but also enhances their wear resistance.

[0032] A first washer 4 is provided between the head of the bolt 2 and the fixing part 11 to connect the bolt 2 threaded part. The first washer 4 is used to increase the contact area between the head of the bolt 2 and the fixing part 11 to reduce the pressure and prevent the fixing part 11 from deforming.

[0033] A second washer 5 is provided between the fixing part 11 and the body of the injection molding machine and the threaded part of the connecting bolt 2. The second washer 5 prevents the fixing part 11 from contacting the body of the injection molding machine, thereby avoiding friction between the lifting ring 1 and the body when the lifting ring 1 rotates, which would cause wear on the body.

[0034] Compared with the prior art, the advantages of this embodiment are: 1. The fixing part 11 and the connecting part 12 are integrally formed to form a fixed overall structure, which avoids the problems caused by the free swing of the traditional lifting ring 1. When the injection molding machine is fixed to the truck frame or cargo ship hull for transportation by the lifting ring 1, it can effectively prevent the injection molding machine from shifting due to vehicle or ship bumps, turns, and swaying, reduce the risk of collision between the injection molding machine and the transport carrier, avoid equipment damage, and eliminate the safety hazards caused by insecure fixing. Furthermore, during hoisting and transfer, this lifting ring assembly can reduce the swaying of the lifting ring 1, making the injection molding machine more stable, reducing operational difficulty and risk, and improving the safety and reliability of the hoisting process; 2. By extending the connecting part 12 away from the injection molding machine body, the lifting hole 14 on the connecting part 12 is far away from the injection molding machine. When the injection molding machine is hoisted, the hoisting rope is also in a position away from the injection molding machine and will not come into contact with the injection molding machine, thereby avoiding the rope from scratching the injection molding machine or putting pressure on the parts of the injection molding machine and causing damage; 3. During hoisting, the connecting part 12 rotates to the upper side, and during transportation, the connecting part 12 rotates to the lower side. Therefore, when the rope is connected to the lifting ring 1, it will not be blocked by the bolt 2, and the operating space is larger.

[0035] Example 2:

[0036] This utility model also discloses an injection molding machine, on which a transport lifting ring assembly as described in Embodiment 1 is installed.
