Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for rotational molding machines, in particular to a supporting device for disassembling a mold of a rotational molding machine. Background Art

[0002] Roto-molding machines are mainly used to produce fuel tanks. In the early stage, powder is filled into the mold on the roto-molding machine, and then the mold is sent to the heating furnace. The powder gradually melts into liquid. The mold is installed on a rotating disk, and the rotating disk is continuously rotated by the rotating mechanism on the roto-molding machine to make the liquid in the mold evenly distributed. After cooling, a fuel tank with a fixed shape is obtained.

[0003] The molds of existing rotational molding machines are usually fixed to the rotating disk with bolts. Since the molds are usually made of metal materials such as iron, they are very heavy. It is very inconvenient for workers to transport and install the molds on the rotating disk, as well as to remove the molds from the rotating disk, which affects the installation efficiency of the molds.

[0004] Therefore, it is necessary to propose a support device for disassembling the mold of a rotational molding machine to improve the installation efficiency of the mold. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the existing rotational molding machine has low mold installation efficiency due to the heavy mold when installing the mold, and now provides a support device for disassembling the mold of the rotational molding machine.

[0006] The technical solution of the utility model is:

[0007] A support device for disassembling a mold of a rotational molding machine includes a frame, a ladder and a lifting mechanism for lifting the mold provided on the frame, the lifting mechanism and the ladder being located on one side of the rotational molding machine, a support platform being provided on the top of the frame and being flush with a rotating disk on the rotational molding machine, the support platform being located on the top of the ladder, and when the lifting mechanism lifts the mold to a maximum height, the mold at the maximum height is located on one side of the support platform and is flush with the support platform;

[0008] The lifting mechanism includes a motor, a winding wheel, a fixed pulley and a loading platform for transporting molds. The motor and the winding wheel are installed at the bottom of the frame. A steel wire rope is wrapped around the winding wheel. One end of the steel wire rope is passed around the fixed pulley and fixedly connected to the loading platform. The motor drives the winding wheel to rotate, and the steel wire rope drives the loading platform to rise and fall.

[0009] Furthermore, an arched passage is provided in the middle of the frame for the rotational molding machine to pass through, and ladders and lifting mechanisms are provided on both sides of the frame.

[0010] Furthermore, the support platforms are located on both sides of the rotating disk.

[0011] Furthermore, four legs are provided at the bottom of the frame for fixing the frame, and the four legs are arranged around the frame.

[0012] Furthermore, a pair of slide rails are fixedly connected to the frame, pulleys are fixedly connected to both sides of the loading platform, the loading platform is located between the pair of slide rails, and the pulleys are slidably connected to the slide rails on the same side.

[0013] Furthermore, the output end of the motor is connected to a reducer, and the output end of the reducer is connected to a winding wheel.

[0014] The utility model relates to a support device for disassembling molds of a rotational molding machine. A worker places the mold on a loading platform on the ground. The loading platform is pulled up by a motor and a steel wire rope to be transported to a support platform. Another worker climbs onto the support platform via an escalator, removes the mold on one side of the support platform from the loading platform, and stores it on the support platform. The molds are all transported to the support platform through a lifting mechanism, which makes it convenient for the worker on the support platform to move the mold to the rotating disk on the rotational molding machine and install and fix it on the rotating disk. Compared with traditional technology, in this technical solution, when workers install the mold, the process of transporting the mold from the ground to the rotating disk no longer requires cumbersome methods such as cranes or manual handling, thereby improving the convenience of mold transportation and installation and improving the installation efficiency of the mold.

The escalator 2 is fixedly connected to the frame 1 by screws, and the lifting mechanism and the escalator 2 are located on one side of the rotational molding machine. As an optional method, a set of lifting mechanisms and escalators 2 can be installed on both sides of the rotational molding machine, thereby adding a workstation and improving the transportation efficiency of the mold 4. A support platform 3 flush with the rotating disk 13 on the rotational molding machine is provided on the top of the frame 1, and the support platform 3 is located on the top of the escalator 2. When the lifting mechanism lifts the mold 4 to the limit height, the mold 4 at the limit height is located on one side of the support platform 3 and flush with the support platform 3.

[0023] like Figure 3 and Figure 4 As shown, the lifting mechanism includes a motor 5, a winding wheel 6, a fixed pulley 7 and a loading platform 8 for transporting the mold 4. The motor 5 and the winding wheel 6 are installed at the bottom of the frame 1. The motor 5 is fixedly connected to the frame 1 with screws. The output end of the motor 5 is connected to the reducer 12. The output end of the reducer 12 is fixedly connected to the winding wheel 6 through a key. A steel wire rope is wound around the winding wheel 6. One end of the steel wire rope passes around the fixed pulley 7 and is bolted to the loading platform 8. The motor 5 drives the winding wheel 6 to rotate, so that the steel wire rope drives the loading platform 8 to rise and fall.

The slide rails 11 can ensure that the lifting route of the loading platform 8 is fixed, thereby improving the stability of the loading platform 8 during transportation.

[0028] During work, a worker on the ground places the mold 4 on the loading platform 8, which is driven by the motor 5 and the wire rope pulls the loading platform 8 up and transported to the support platform 3. Another worker climbs up to the support platform 3 through the escalator 2, removes the mold 4 on one side of the support platform 3 from the loading platform 8, and stores it on the support platform 3. Through the lifting mechanism, all the molds 4 are transported to the support platform 3, which is convenient for the workers on the support platform 3 to move the mold 4 to the rotating disk 13 on the rotational molding machine and install it on the rotating disk 13. Compared with traditional technology, in this technical solution, when workers install the mold 4, the process of transporting the mold 4 from the ground to the rotating disk 13 no longer requires cumbersome methods such as cranes or manual handling, which improves the convenience of transportation and installation of the mold 4 and improves the installation efficiency of the mold 4.
