Description

Technical Field

[0001] This utility model relates to the field of tie rod assembly technology, and in particular to an auxiliary assembly mechanism and transfer device for tie rods of die casting machines or injection molding machines. Background Technology

[0002] In existing technologies, such as Figure 1 As shown, the installer ties the lifting rope to the tie rod, aligning the center of the tie rod with the center of the tie rod hole in the tail plate as much as possible. The tie rod is then propelled forward by the movement of the crane or the insertion of a forklift. Finally, the tie rod passes through the tail plate of the die-casting machine or injection molding machine to the head plate, thus completing the assembly of the tie rod.

[0003] Due to the length and weight of the tie rod, the following problems still exist in the assembly process using existing technology: First, the assembly of the tie rod from the tail plate to the head plate using a crane or forklift requires constant operation and supervision, making assembly difficult and time-consuming; Second, the large force applied by the crane and forklift makes it impossible to control the installation force, and if there are quality problems, it may still be installed, resulting in forced assembly and making it impossible to guarantee assembly quality; Third, excessive force during tie rod assembly can damage parts such as steel sleeves and may also cause the head plate, tail plate, and other templates to tip over, posing a significant safety hazard.

[0004] Based on this, an auxiliary assembly mechanism and transfer device for tie rods of a die casting machine or injection molding machine are provided. Utility Model Content

[0005] The present invention aims to overcome the defects in the prior art and provide an auxiliary assembly mechanism and transfer device for tie rods of die casting machines or injection molding machines.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an auxiliary assembly mechanism for a tie rod of a die-casting machine or injection molding machine, comprising a support frame, the support frame including a support plate having a through hole; a winch fixed to the support plate, one end of which is wound with a cloth strip, the other end of which extends through the through hole into the support frame; and a pulley mechanism located inside the support frame, the pulley mechanism including a pulley with the other end of the cloth strip wound around it and a hook located at the front end of the pulley for hooking the tie rod lifting eye screw; the winch is activated to retract the cloth strip, thereby the pulley mechanism drives the tie rod forward through the head plate to the designated position.

[0007] As a preferred embodiment of this utility model, the winch includes a protection circuit mechanism for overload power-off of the winch.

[0008] In a preferred embodiment of this utility model, the support frame includes a guide frame, which includes a pull rod ring that guides the pull rod and a support rod that fixes the pull rod ring to the support plate. The pull rod ring and the support plate are coaxially arranged.

[0009] In a preferred embodiment of this utility model, the inner diameter of the pull rod ring is larger than the outer diameter of the pull rod, and there are at least three support rods, with the support rod rings arranged circumferentially around the pull rod ring.

[0010] In a preferred embodiment of this utility model, the pulley mechanism includes a bracket, which includes symmetrical fixed plates and fixed rods connecting the symmetrical fixed plates.

[0011] In a preferred embodiment of this utility model, the fixing rod includes a first fixing rod for fixing the hook and a second fixing rod for supporting the hook, wherein the diameter of the first fixing rod is larger than the diameter of the second fixing rod.

[0012] In a preferred embodiment of this utility model, the pulley is located at the center of the bracket and is fixed between two symmetrical fixed plates.

[0013] A transfer device for a tie rod auxiliary assembly mechanism of a die casting machine or injection molding machine includes a tie rod auxiliary assembly mechanism, a tooling trolley, and a circuit placement mechanism. The tie rod auxiliary assembly mechanism is located at one end of the tooling trolley, and the circuit placement mechanism is located at the other end of the tooling trolley. The circuit placement mechanism houses the protection circuit mechanism of the winch and the wires in the tie rod auxiliary assembly mechanism.

[0014] As a preferred embodiment of this utility model, the tooling trolley includes a support base, universal wheels fixedly disposed at the bottom of the support base, and a first positioning block and a second positioning block fixedly disposed at the top of the support base. The first positioning block is used to support the support rod, and the second positioning block limits the movement of the support plate on both sides.

[0015] As a preferred embodiment of this utility model, the circuit placement mechanism includes a wire reel, a protective electrical box, and a wire support frame arranged in sequence. The wire support frame is used to place the wire of the winch, the wire reel can store the extended wire, and the protective electrical box houses the protective circuit mechanism of the winch.

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

[0017] 1. This utility model has two advantages. First, by selecting a winch that can be matched with the pulling force corresponding to the weight of the tie rod, it avoids violent assembly caused by excessive pulling force, which could lead to the collapse of the template and damage to the parts. Second, when there is a problem with the fit between the tie rod and the tie rod hole, the protection circuit mechanism equipped with the winch will cut off the power in time, which is conducive to the timely adjustment of the tie rod in the tie rod hole.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-5As shown, an auxiliary assembly mechanism for a tie rod of a die-casting machine or injection molding machine includes a support frame 1, which includes a support plate 11 with a through hole 111; a winch 2 fixed to the support plate 11, with one end of a cloth strip 3 wound around the winch 2, and the other end of the cloth strip 3 extending into the support frame 1 through the through hole 111; and a pulley mechanism 4 located inside the support frame 1, which includes a pulley 41 wound around the other end of the cloth strip 3 and a hook 42 located at the front end of the pulley 41 for hooking the eye bolt of the tie rod 100; the winch 2 is activated to retract the cloth strip 3, and the pulley mechanism 4 then drives the tie rod 100 forward through the head plate to a designated position.

[0028] It should be noted that the pulley mechanism 4 is essentially a lever with a power arm twice the length of the resistance arm, which can amplify the applied force by two times. If an object weighing M needs to be lifted, the actual pulling force required when using the pulley mechanism 4 is 1 / 2M. Correspondingly, the torque provided by the winch 2 motor will also be halved. Since the power of the winch 2 motor is proportional to the output torque, when the output torque decreases, the power of the motor will also decrease accordingly. Compared with the force applied by overhead cranes and forklifts, the winch 2 can be selected according to the weight of the pull rod 100, controlling the amount of force applied, so that the force applied is not too large, avoiding the occurrence of violent assembly, and ensuring the assembly quality.

[0029] Furthermore, the winch 2 includes a protection circuit mechanism 21 for overload power-off of the winch 2.

[0030] The circuit diagram of the protection circuit mechanism 21 is as follows: Figure 5 As shown, F1 is an air switch, KA1 is a current monitoring module, KM1 is a small two-phase AC contactor, and M1 is a winch. When the air switch F1 is opened and pushed up, since KA1 is a normally closed contact, the KM1 coil circuit is complete at this time, the KM1 coil is energized, and the KM1 contact operates. The normally open contact of KM1 closes and becomes a normally closed contact, the winch 2 circuit is complete and energized, and the winch 2 starts to work.

[0031] When the tie rod 100 gets stuck during the operation of the tie rod auxiliary assembly mechanism, the winch 2 motor is overloaded, and the current in the motor power supply circuit surges. The current monitoring module KA1 detects that the current value through B1 and B2 far exceeds the safety setting value. At this time, the current monitoring module KA1 instructs the KA1 contact to operate, and the normally closed contact of KA1 opens to become a normally open contact. At this time, the KM1 coil circuit is incomplete, the KM1 coil is de-energized, and the normally closed contact of KM1 in the working state returns to the normally open contact. The winch 2 circuit is incomplete and power is cut off, and the winch 2 stops working. Compared with the operation of overhead cranes and forklifts, when the tie rod 100 has an assembly problem, it can be stopped in time. On the one hand, it will not cause damage to parts such as steel sleeves, nor will it cause the head plate, tail plate and other templates to tip over, avoiding safety hazards. On the other hand, it does not require constant supervision of the assembly operation, which is more convenient.

[0032] In use, first use a crane to lift the tie rod 100 and pass it through the tail plate. Then, use the crane to lift the tie rod auxiliary assembly mechanism to the head plate. Align the tie rod auxiliary assembly mechanism with the tie rod hole in the head plate, loosen the cloth belt 3 of the tie rod auxiliary assembly mechanism, and then move the pulley mechanism 4 to the tie rod 100. Hook the hook 42 of the pulley mechanism 4 onto the eye bolt of the tie rod 100. Start the winch 2 to cause the cloth belt 3 to retract, thereby driving the tie rod 100 forward. Fully pass the tie rod 100 through the head plate to the designated position, loosen the cloth belt 3, and remove the hook 42 from the eye bolt of the tie rod 100. The assembly of the tie rod 100 is now complete.

[0033] On the one hand, this utility model can adapt the selection of winch 2 to the pulling force corresponding to the weight of tie rod 100, avoiding violent assembly caused by excessive pulling force, which could lead to the tilting of the template and damage to parts. On the other hand, when there is a problem with the fit between tie rod 100 and tie rod hole, the protection circuit mechanism 21 equipped with winch 2 will cut off the power in time, which is conducive to the timely adjustment of tie rod 100 in tie rod hole.

[0034] Compared to the rigid pushing or insertion by a crane or forklift, this utility model does not require changing the position of the tie rod auxiliary assembly mechanism. The tie rod 100 can be assembled simply by the winch 2 driving the pulley mechanism 4, making the assembly simple and convenient.

[0035] like Figures 2-3 As shown, the support frame 1 includes a guide frame 12, which includes a pull rod ring 121 that guides the pull rod 100 and a support rod 122 that fixes the pull rod ring 121 to the support plate 11. The pull rod ring 121 and the support plate 11 are coaxially arranged. The inner diameter of the pull rod ring 121 is larger than the outer diameter of the pull rod 100. There are at least three support rods 122, and the support rods 122 are arranged circumferentially around the pull rod ring 121. The multiple support rods 122 can stably support the pull rod ring 121, ensuring the guiding function of the pull rod ring 121 on the pull rod 100.

[0036] Meanwhile, the through hole 111 is located at the center of the support plate 11, and correspondingly, the pulley mechanism 4 passing through the through hole 111 is located at the center of the tie rod ring 121.

[0037] The pulley mechanism 4 includes a bracket 43, which includes symmetrical fixed plates 431 and fixed rods 432 connecting the symmetrical fixed plates 431. There are at least three fixed rods 432 to ensure the strength and stability of the bracket 43. The fixed rods 432 include a first fixed rod 4321 for fixing the hook 42 and a second fixed rod 4322 for supporting. The diameter of the first fixed rod 4321 is larger than that of the second fixed rod 4321. The larger diameter of the first fixed rod 4321 improves its strength and load-bearing capacity.

[0038] The pulley 41 is located at the center of the bracket 43, and the pulley 41 is fixed between two symmetrical fixed plates 431.

[0039] The fixing rod 432 is fixedly installed between the fixing plates 431 by bolts or welding, and the pulley 41 is fixedly installed between the fixing plates 431 by bolts or welding.

[0040] In use, the pull rod ring 121 abuts against the head plate and is positioned and fixed on the head plate by other clamps. The pulley mechanism 4 is confined inside the support frame 1. The hook 42 of the pulley mechanism 4 is hooked onto the eye bolt of the pull rod 100. The winch 2 is started, so that the pulley mechanism 4 drives the pull rod 100 to pass through the tail plate and the head plate in sequence to the specified position.

[0041] like Figure 4 As shown, a transfer device for a tie rod auxiliary assembly mechanism of a die casting machine or injection molding machine includes a tie rod auxiliary assembly mechanism, a tooling trolley 5, and a circuit placement mechanism 6. The tie rod auxiliary assembly mechanism is provided at one end of the tooling trolley 5, and the circuit placement mechanism 6 is provided at the other end of the tooling trolley 5. The circuit placement mechanism 6 stores the protection circuit mechanism 21 of the winch 2 and the wires in the tie rod auxiliary assembly mechanism.

[0042] The tooling trolley 5 includes a support base 51, casters 52 fixedly disposed at the bottom of the support base 51, and a first positioning block 53 and a second positioning block 54 fixedly disposed at the top of the support base 51. The first positioning block 53 is used to support the support rod 122, and the second positioning block 54 limits the movement of the support plate 11 on both sides.

[0043] The circuit mounting mechanism 6 includes a wire reel 61, a protective electrical box 62, and a wire support frame 63 arranged in sequence. The wire support frame 63 is used to mount the wires of the winch 2. The wire reel 61 can store the extended wires. The protective electrical box 62 houses the protective circuit mechanism 21 of the winch 2.

[0044] In use, the first positioning block 53 and the second positioning block 54 of the tooling trolley 5 position the tie rod auxiliary assembly mechanism. The caster wheel 52 of the tooling trolley 5 can drive the positioned tie rod auxiliary assembly mechanism to the designated area and perform auxiliary tie rod assembly operations. The wire reel 61 on the circuit placement mechanism 6 can hold the extended wire, expanding the application range of the auxiliary tie rod assembly mechanism. The protective electrical box 62 on the circuit placement mechanism 6 protects the protective circuit mechanism 21, which is beneficial for the tie rod auxiliary assembly mechanism to carry out operations.

[0045] The transfer device of this utility model facilitates the transfer of the tie rod auxiliary assembly mechanism, enabling the tie rod auxiliary assembly mechanism to quickly perform tie rod auxiliary operations and improving the assembly efficiency of tie rod 100.
