DETAILED DESCRIPTION
[0023] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor also belong to the scope of protection of the present application.
[0024] As shown in Figures 1-3 , a mold overturning mechanism disclosed by the present application comprises an equipment rack 1, the top of the equipment rack 1 is provided with a rotating frame 2, and the middle positions of one opposite side of the rotating frame 2 are rotationally connected with the equipment rack 1 through a rotating shaft 3.
[0025] The middle of the rotating frame 2 is provided with a mold fixing module 4, which is used for fixing a mold to be overturned on the rotating frame 2.
[0026] One side of the rotating frame 2 is provided with power equipment 5 and the two are connected together, and the power equipment 5 can drive the rotating frame 2 to overturn around the rotating connection point of the rotating frame 2 and the equipment rack 1.
[0027] In the above embodiment, the equipment rack 1 of the device is a device base skeleton welded by a plurality of square tubes, which can provide a mounting base for components such as the rotating frame 2. A rotating shaft 3 is fixedly installed at a middle position of a relative side of the rotating frame 2 in the length direction, and the two rotating shafts 3 are rotationally connected with the corresponding side of the equipment rack 1. Thus, driving the rotating frame 2 to rotate around the rotating shaft 3 on the equipment rack 1 can realize the effect of overturning the rotating frame 2. The rotating frame 2 of the device is a square frame structure, and the mold fixing module 4 in the middle thereof can form an integrated structure with the mold to be overturned after the mold to be overturned is fixed. In the process of overturning the rotating frame 2, the mold will also be overturned to realize the effect of overturning the mold. In this process, the rotating frame 2 always maintains a stable connection relationship with the equipment rack 1, and the mold is always fixed firmly in the mold fixing module 4. Thus, compared with manually overturning a mold that is large in volume and weight, the risk of damage to the mold due to human factors (such as the mold slipping or falling due to coordination failure of multiple workers in the process of overturning the mold) can be effectively reduced, and the safety risk of the mold to workers in the process of overturning can also be effectively avoided. The device further connects the power equipment 5 on one side of the rotating frame 2. The power equipment 5 can automatically drive the rotating frame 2 to overturn the mold. Thus, not only can the human cost of the enterprise be effectively saved, but also the operation is simple and convenient, time-saving and labor-saving.
[0028] Further, as shown in Figure 1 and Figure 3 , the mold fixing module 4 includes two angle irons 41 arranged in parallel on the rotating frame 2. The two ends of the angle iron 41 are fixed on the rotating frame 2 by bolts and nuts. The distance between the two angle irons 41 is equal to the length of the mold to be overturned. A plurality of limiting plates 42 are welded on the area of the rotating frame 2 between the same ends of the two angle irons 41, and the limiting plates 42 are located on the side opposite to the angle iron 41 on the rotating frame 2.
[0029] In the above embodiment, the frame of the mold is generally rectangular in structure, and the upper and lower sides of the edge are right angles. When the mold is clamped on the limiting plate 42 by the angle iron 41, the shape of the angle iron 41 is just matched with the right angle edge of the mold. In this way, the mold can be effectively clamped on the limiting plate 42, and the risk of mold shaking is reduced. The limiting plate 42 for placing the mold is installed on the rotating frame 2 away from the side of the angle iron 41. In this way, a certain space can be provided between the limiting plate 42 and the angle iron 41 for placing the mold to be turned over. Since the specifications of the molds to be turned over in actual production are not uniform, a plurality of limiting plates 42 are uniformly welded on the opposite side of the area between the two angle irons 41. In this way, when molds of different specifications need to be turned over, the molds can be placed on the limiting plate 42 matching the size of the mold and fixed by the angle iron 41. The application range and application scenarios of the present application are effectively improved. The angle iron 41 is fixed to the rotating frame 2 by bolts and nuts after clamping the mold placed on the limiting plate 42. In this way, the mold can be fixed with high efficiency when in use, and the angle iron 41 can be conveniently and quickly disassembled to release the limitation on the mold after use.
[0030] Further, as shown in Figure 1 , the bolts for mounting the angle iron 41 are welded on the rotating frame 2.
[0031] In the above embodiment, the distance between the lower side of the angle iron 41 and the limiting plate 42 after being placed on the rotating frame 2 is the same as the thickness of the edge of the mold. To fix the mold on the rotating frame 2, the mold needs to be placed on the limiting plate 42 first. If the bolts and the rotating frame 2 are separately arranged, the worker will be hindered during the assembly process of the bolts. Therefore, the present application chooses to weld the bolts on the rotating frame 2 in advance. At this time, to fix the angle iron 41 on the rotating frame 2, the bolts need to be inserted from the reserved holes at both ends of the angle iron 41, and then the nuts are screwed on the bolts. In this way, the use is more convenient. Similarly, since the molds to be turned over in actual production may have multiple specifications, the present application can weld multiple bolts on the rotating frame 2 to ensure that the angle iron 41 can be fixed by the corresponding bolts when the molds of different specifications are placed on the limiting plates 42 at different positions.
[0032] Further, as shown in Figure 1 and Figure 3 , one of the long sides of the rotating frame 2 is fixedly connected with a support 6 at both ends. The distance between the two ends of the two supports 6 away from each other is equal to the length of the horizontal cross section of the equipment rack 1.
[0033] In the above embodiment, the edge profile of the rotating frame 2 is rectangular, same as the cross section of the equipment rack 1. In order to ensure smooth overturning in the equipment rack 1, the length of the rotating frame 2 is smaller than the length between the two side walls of the equipment rack 1. The mold is in a horizontal state in the initial state and after overturning 180°. The support points are mainly the two rotating shafts 3 at the middle position of one of the opposite sides of the rotating frame 2. Therefore, when the workers demold, process or clean the mold, the rotating frame 2 as a whole still has the risk of tilting or deflecting. Therefore, the two ends of one of the long edges of the rotating frame 2 are respectively provided with an outwardly extending support part 6. When the rotating frame 2 is in a horizontal state, in addition to the support point of the rotating shaft 3 in the middle, the end of the rotating frame 2 provided with the support part 6 also provides support for the rotating frame 2 by being placed on the corresponding end of the equipment rack 1, thereby ensuring the stability of the rotating frame 2 in the horizontal state.
[0034] Further, as shown in Figure 1 and Figure 2 , the outer side of the support part 6 is fixedly connected with a hook 7, and the outer side of the four corners of the upper end of the equipment rack 1 is provided with a buckle 8 matched with the hook 7.
[0035] In the above embodiment, on the basis of the previous embodiment, in order to further improve the stability of the rotating frame 2 in the horizontal state, a buckle 8 matched with the hook 7 on the support part 6 is installed on the outer side of the four corners of the upper end of the equipment rack 1. Therefore, no matter which side the end of the rotating frame 2 provided with the support part 6 is turned to, the rotating frame 2 can be fixed by the buckle 8 at the corresponding position, so as to improve the stability during demolding, cleaning or processing.
[0036] Further, as shown in Figure 1 and Figure 2 , the power equipment 5 includes a driven wheel 51, the driven wheel 51 is fixedly connected with one of the rotating shafts 3 on the rotating frame 2, the lower side of the driven wheel 51 is provided with a driving wheel 52, and the two are connected through a transmission belt 53, the driving wheel 52 is installed on the power output shaft of a speed reducer 54, the power input shaft of the speed reducer 54 is connected with the power output end of a motor 55, the speed reducer 54 and the motor 55 are fixedly installed on the same side plate 56, and the side plate 56 is fixedly connected with the equipment rack 1 through a side support 57.
[0037] In the above embodiment, the motor 55 of the present application can transmit power to the driving wheel 52 through the speed reducer 54 when working, and since the driving wheel 52 and the driven wheel 51 are connected through the transmission belt 53, the driven wheel 51 is connected with the rotating shaft 3 at one end of the rotating frame 2, so that the power at the driving wheel 52 can be transmitted to the rotating frame 2 through the driven wheel 51, thereby achieving the effect of driving the rotating frame 2 to rotate around the rotating shaft 3. Compared with the manual mold overturning method in the prior art, the mold overturning method by the motor 55 of the present application is obviously more efficient and labor-saving.
[0038] Further, as shown in Figure 1 and Figure 2 , the tool placing box 9 is welded at the lower half of the equipment rack 1, one side of the tool placing box 9 is provided with a freely openable and closable door plate; the tool placing block 10 is installed on the side of the upper half of the equipment rack 1 opposite to the power equipment 5, and a plurality of holes for placing tools are formed on the upper side of the tool placing block 10.
[0039] In the above embodiment, the tool placing box 9 arranged on the lower half of the equipment rack 1 of the present application can make full use of the space on the equipment rack 1, and through the freely openable and closable door plate on the tool placing box 9, workers can store some accessories or tools that may be used in this process, and through the tool placing block 10 on the equipment rack 1, some small tools for cleaning or processing molds can be temporarily placed, so that the practicability of the equipment of the present application can be effectively improved.
[0040] Further, the motor 55 is a stepping motor 55, and the speed reducer 54 is a worm gear reducer.
[0041] In the above embodiment, the motor 55 of the present application is a stepping motor 55, which is convenient for controlling the angle of rotation during the overturning process, and when the stepping motor 55 rotates to a specified angle, the positioning self-locking function can be realized in cooperation with the worm gear reducer, so as to prevent the rotating frame 2 from being deflected at a specific angle.
[0042] Further, the top of the tool placing box 9 is installed with a lifting platform (the lifting platform is a kind of lifting equipment commonly used in the mechanical field, and the lifting platform of the present application is not shown in the drawings).
[0043] In the above embodiment, since there is a high gap between the rotating frame 2 on which the mold is installed and the top of the tool placing box 9 on which the mold can be placed nearby, it is still laborious to manually place the mold on the limiting plate 42 in the mold fixing module 4, therefore, the lifting platform is further installed on the top of the tool placing box 9 to assist workers to quickly and labor-savingly assemble the mold into the mold fixing module 4.
[0044] The implementation principle of the embodiment is that when the mold needs to be flipped, the worker can first place the mold on the limiting plate 42 in the rotating frame 2, and then fix the mold through the angle iron 41. Next, the motor 55 can be started to drive the rotating frame 2 to rotate on the equipment rack 1, thereby realizing the flipping effect of the mold. Compared with the prior art, the mold flipping mechanism of the application can not only reduce labor costs and improve production efficiency, but also ensure the safety of the mold and the worker during the flipping process. The mold flipping mechanism of the application can be widely applied in many industrial fields, including but not limited to large-size bipyramid workpiece machining processes or other occasions requiring mold flipping.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the application, and not to limit them; although the application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for part or all of the technical features; and these modifications or substitutions do not make the essence of the corresponding technical solution deviate from the scope of the technical solutions of the embodiments of the application.
