Description

Technical Field

[0001] This utility model relates to the field of casting mold flipping and maintenance equipment, and more specifically, to a casting mold flipping tooling. Background Technology

[0002] After a period of use, casting molds require routine maintenance by fitters or spray painters, which necessitates flipping them. The current flipping process involves fixing two lifting rings at one end of the mold and then using a crane to repeatedly pull the rings before flipping the mold. This repeated pulling and flipping process by the crane can easily cause the mold cavity to be impacted and deformed, which in turn affects the casting effect of subsequent workpieces and results in defective products. In conclusion, the casting mold flipping process needs further improvement. Utility Model Content

[0003] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a casting mold flipping tool.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A casting mold flipping fixture includes a base plate, a fixed frame, a traveling assembly, a movable frame opposite to the fixed frame, a mounting base, flat wheels, a brake assembly, a flipping shaft, and a mounting block.

[0006] The fixed frame and the traveling components are all fixed to the base plate;

[0007] The movable frame is fixed on the traveling component, and two sets of symmetrically distributed mounting seats are fixed on both the fixed frame and the movable frame;

[0008] The flat wheel is rotatably connected to the mounting base;

[0009] The base plate and the movable frame are connected by a brake assembly to prevent the movable frame from moving during the placement and flipping of the casting mold;

[0010] Two mounting blocks are respectively movably mounted on both sides of the center of gravity of the casting mold, and the two mounting blocks are welded with a flipping shaft that contacts the two sets of flat wheels.

[0011] Furthermore, the brake assembly includes a rack, a fixing block, a brake lever, and a notch. The rack is fixed on the base plate, the fixing block is fixed on the movable frame, and a brake lever with a main body shaped like a boomerang is rotatably connected to the fixing block. The brake lever has a notch that cooperates with the rack.

[0012] The above solution uses a braking component to limit the position of the movable frame during the placement and flipping of the casting mold, thereby avoiding the safety hazard of the casting mold falling. In addition, the horizontal position of the movable frame can be adjusted according to the casting mold of different sizes to improve the adaptability of this tooling to the flipping operation of casting molds of different sizes.

[0013] Furthermore, the mounting block has several threaded holes, and fixing bolts are installed in the threaded holes. The fixing bolts pass through the threaded holes and engage with the threads on both sides of the center of gravity of the casting mold.

[0014] The above solution can bolt a fixed block with a flipping shaft to both sides of the center of gravity of each size casting mold to facilitate the subsequent flipping operation of the casting mold onto this tooling.

[0015] Furthermore, the walking assembly includes an I-beam and a single-sided track wheel. The I-beam is symmetrically fixed on the base plate and the single-sided track wheel is fitted on the I-beam. The single-sided track wheel is fixedly connected to the movable frame.

[0016] The above solution allows the movable frame to move horizontally on the base plate via a walking component, while always being directly opposite the fixed frame during the movement.

[0017] Furthermore, one of the said flipping shafts is fixed with a double limiting plate at the end away from the mounting block.

[0018] The above solution can prevent the movable frame from moving excessively during the casting mold flipping process and thus causing the casting mold to fall, by using a double limit plate after the brake assembly is damaged.

[0019] Furthermore, the mounting block is integrally formed with the flipping shaft.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] Compared to existing technologies, this device hoists and places the casting mold, which has a tilting shaft installed on both sides of the center of gravity, onto the fixture. Then, it can be manually driven to rotate the cavity of the casting mold to the upper surface, making it convenient for subsequent maintenance by fitters or spray painters. The operation is convenient, and the cavity will not be subjected to collisions during the casting mold tilting process, thus effectively reducing the probability of deformation of the casting mold cavity. The tilting process is optimized. At the same time, this fixture can tilt casting molds of various sizes, increasing the adaptability. The movable frame will not move during the placement and tilting of the casting mold, thus preventing the casting mold from falling, resulting in better performance. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0029] like Figures 1 to 3 As shown, a casting mold flipping fixture includes a base plate 1, a fixed frame 2, a traveling assembly, a movable frame 3 opposite to the fixed frame 2, a mounting base 4, flat wheels 5, a brake assembly, a flipping shaft 6, and a mounting block 7.

[0030] The fixed frame 2 and the traveling components are both fixed on the base plate 1;

[0031] The movable frame 3 is fixed on the traveling component, and two sets of symmetrically distributed mounting seats 4 are fixed on the fixed frame 2 and the movable frame 3.

[0032] The flat wheel 5 is rotatably connected to the mounting base 4;

[0033] The base plate 1 and the movable frame 3 are connected by a brake assembly to prevent the movable frame 3 from moving during the placement and flipping of the casting mold;

[0034] Two mounting blocks 7 are respectively movably mounted on both sides of the center of gravity of the casting mold, and the two mounting blocks 7 are welded with a flipping shaft 6 that contacts the two sets of flat wheels 5.

[0035] In a further optimization of the above embodiment, the mounting block 7 and the flip shaft 6 are integrally formed to improve the connection strength.

[0036] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 3 As shown, the brake assembly includes a rack 8, a fixing block 9, a brake lever 10, and a notch 11. The rack 8 is fixed on the base plate 1, the fixing block 9 is fixed on the movable frame 3, and the brake lever 10, which is rotatably connected to the fixing block 9, has a main body shaped like a boomerang. The brake lever 10 has a notch 11 that cooperates with the rack 8.

[0037] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, the mounting block 7 has several threaded holes, and fixing bolts are installed in the threaded holes. The fixing bolts pass through the threaded holes and are threadedly engaged with the two sides of the center of gravity of the casting mold. The threaded holes are shown in the figure but are not labeled. The fixing bolts are not shown in the figure.

[0038] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 3 As shown, the walking assembly includes an I-beam 12 and a single-sided track wheel 13. The I-beam 12 is symmetrically fixed on the base plate 1 and the single-sided track wheel 13 is fitted on the I-beam 12. The four single-sided track wheels 13 are respectively fixed to the movable frame 3.

[0039] The working process of this utility model is as follows:

[0040] Before maintenance, the fitter or painter first locates the center of gravity of the current casting mold. Then, a mounting block 7 is bolted to each side of the center of gravity. After the mounting blocks 7 are installed, the casting mold is transferred to the area above the tilting fixture using a hoisting device (i.e., an overhead crane). The hoisting device then drives the casting mold downwards so that the two tilting shafts 6 contact the two sets of flat wheels 5 respectively. One tilting shaft 6 is positioned between two flat wheels 5 in one set and partially contacts both flat wheels 5, as detailed in the attached instruction manual. Figure 1 The state shown;

[0041] In addition, since the casting molds to be maintained are of different sizes, mounting blocks 7 and flipping shafts 6 can be installed on both sides of the center of gravity of each casting mold of different sizes before maintenance to facilitate subsequent manual flipping operations.

[0042] It should be noted that, initially, before the casting mold is placed, lifting the left end of the brake lever 10 upwards will disengage the notch 11 from the rack 8. Then, the horizontal position of the movable frame 3 can be adjusted left and right using the travel assembly to ensure that the two tilting shafts 6 are stably placed on the two sets of flat wheels 5, with the mounting blocks 7 and mounting seats 4 spaced apart. After adjustment, the brake lever 10 is released. At this point, the brake lever 10 will naturally deflect under its own weight and will be positioned between two adjacent racks 8, as detailed in the attached instruction manual. Figure 3In the state shown, the movable frame 3 can neither move away from the fixed frame 2 nor get closer to the fixed frame 2. This allows for corresponding adjustments to be made according to different sizes of casting molds to improve the size compatibility range of the casting molds to be flipped for maintenance.

[0043] Finally, the fitter or sprayer can stand on one side of the casting mold and manually apply force to achieve flexible flipping of the casting mold, and the casting mold will not be deformed during the flipping process.

[0044] Compared to existing technologies, this device hoists and places the casting mold, which has a tilting shaft installed on both sides of the center of gravity, onto the fixture. Then, it can be manually driven to rotate the cavity of the casting mold to the upper surface, making it convenient for subsequent maintenance by fitters or spray painters. The operation is convenient, and the cavity will not be subjected to collisions during the casting mold tilting process, thus effectively reducing the probability of deformation of the casting mold cavity. The tilting process is optimized. At the same time, this fixture can tilt casting molds of various sizes, increasing the adaptability. The movable frame will not move during the placement and tilting of the casting mold, thus preventing the casting mold from falling, resulting in better performance.

[0045] In some embodiments, such as Figure 4 As shown, one of the flipping shafts 6 is fixed at one end away from the mounting block 7 with a double limiting plate 14 that is spaced apart from the flat wheel 5 and the mounting seat 4. In this embodiment, when the brake assembly is damaged, the double limiting plate 14 can prevent the movable frame 3 from moving in a large range during the flipping process of the casting mold, which would cause the casting mold to fall. This is a second safety protection measure.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
