Description

Technical Field

[0001] The utility model belongs to the technical field of aerated concrete production equipment, and more specifically relates to a turning device of a casting mold vehicle and a flip demoulding machine. Background Art

[0002] In the current construction industry, aerated concrete structures are widely used as non-load-bearing components due to their unique advantages such as high strength, hardness, light weight, low cost, easy raw material availability, and convenient processing. In the production process of building blocks, the slurry is first poured into the mold car, foamed, cured, demolded, and then cut.

[0003] The current demoulding technology is to hook the hook of the mold car through the grabber of the flip machine, and then flip it 90 degrees for demoulding. For example, in the patent CN202964883U, a fully automatic flip demoulding hanger for an aerated concrete production line is disclosed. In this application, the mold flipping action can be realized by flipping the hanger; at the same time, through the setting of the hanger positioning device, the automatic and precise positioning of the hanger can be realized, making the clamping and flipping operations of the flip hanger safer and more reliable. For another example, in the patent CN103921344A, a mold opening and closing device of an empty flip demoulding machine is disclosed. In this application, by lowering the lifting beam to the working position of the mold car, the hook grabs the lifting lug on the mold car and locks it, driving the mold car to complete a 90° flip to complete the flipping action of the mold car. At the same time, the mold opening and closing drive device cooperates with the mold car side plate hook, so that the force required for opening and closing the mold is smaller, and the movement is stable and smooth.

[0004] The above applications all involve structural improvements to the flip demoulding machine. However, the flip and lifting functions of the existing flip demoulding machine for the flip mold cart remain at the point where the flip demoulding machine needs to first move directly above the mold cart, and then the lifting device and flip hook are lowered to the lifting lug position of the mold cart and grab the mold cart. Since the flip hook needs to pass over the mold cart first, the lifting process takes a long time, and the lifting time of the flip hook accounts for a large proportion of the operating time of the single machine.

[0005] Under the environmental trend of improving production efficiency and shortening the single-machine operation time of equipment, this method greatly reduces production efficiency and increases production costs. Therefore, the market needs a new type of flip demoulding machine with high automation and high production efficiency to improve this phenomenon. Utility Model Content

[0006] 1. Problems to be solved

[0007] In view of the problem that the existing flip demoulding machine has a long action cycle, which is not conducive to improving work efficiency, the utility model provides a flipping device and a flip demoulding machine for a casting mold trolley. The utility model can realize the clamping and flipping operations of the mold trolley by moving the flip mechanism horizontally for a short distance, effectively reducing the moving path of the flipping device, reducing the operating time of a single machine, and is conducive to improving work efficiency.

[0008] 2. Technical solution

[0009] In order to solve the above problems, the technical solution adopted by the utility model is as follows:

[0010] The utility model discloses a turning device for a casting mold vehicle, comprising a lifting mechanism, wherein the lifting mechanism is provided with a turning mechanism, wherein the turning mechanism is provided with two groups, and the two groups of turning mechanisms can horizontally slide away from or close to each other along the length direction of the lifting mechanism;

[0011] The flipping mechanism comprises a mounting frame slidably arranged on the lifting mechanism, and flipping parts are rotatably arranged on the opposite side walls of the two mounting frames. The flipping parts engage the lifting ears on the mold cart from both ends of the mold cart and drive the mold cart to flip.

[0012] Furthermore, the flip part includes a flip plate and a slot arranged on the flip plate for the ear to be inserted into, wherein the flip plate is arranged on the mounting frame through a bearing.

[0013] Furthermore, the mounting frame is in an inverted L-shape as a whole, the horizontal section of which is connected to the lifting mechanism, the flipping portion is arranged on the vertical section of the mounting frame, and the vertical sections of the two mounting frames are arranged to be far away from each other.

[0014] Furthermore, the mounting frame is connected to a horizontal driving source for driving it to move horizontally, and the flip plate is connected to a flip driving source for driving it to rotate.

[0015] Furthermore, the horizontal driving source and the flipping driving source are oil cylinders, air cylinders or electric push rods.

[0016] Furthermore, the lifting mechanism comprises a group of lifting columns arranged opposite to each other and a lifting beam located between the lifting columns, the horizontal driving source is arranged on the lifting beam, and the mounting frame and the lifting beam are slidably matched through a linear guide pair.

[0017] Furthermore, the linear guide pair comprises a slider arranged on the top of the mounting frame, and a guide rail arranged on the lifting beam and cooperating with the slider.

[0018] The utility model discloses a flip demoulding machine, which comprises a frame and a traveling assembly arranged on the frame, wherein the flipping device is arranged on the traveling assembly.

[0019] Furthermore, a mold opening and closing mechanism for opening and closing the side panels of the mold vehicle is also provided at the bottom of the lifting beam.

[0020] The method for demoulding using the above-mentioned flip demoulding machine comprises the following steps:

[0021] S1. The mold cart is transferred to a predetermined workstation; at this time, the flipping parts of the flipping device are located at both ends of the mold cart;

[0022] S2, the horizontal driving source is activated to drive the two flipping parts to move toward each other, so that the flipping parts and the lifting ears on the mold cart are engaged with each other, thereby grabbing the mold cart;

[0023] S3, the flip driving source is activated to drive the flipping part to flip, thereby realizing the flipping operation of the mold vehicle.

[0024] 3. Beneficial effects

[0025] Compared with the prior art, the beneficial effects of the utility model are:

[0026] (1) The utility model discloses a flipping device for a casting mold trolley, wherein two flipping mechanisms can move laterally, and the maximum distance between the two flipping mechanisms when they are opened to each other is greater than the length of the mold trolley, so that the mold trolley can be grasped and released by retracting or opening the two flipping mechanisms. Compared with a traditional flipping device, which needs to move over the mold trolley and then move down to grasp the mold trolley, the flipping device of the utility model can move laterally and clamp from both ends of the mold trolley, which can effectively reduce the moving path of the flipping device, reduce the operating time of a single device, and is conducive to improving work efficiency.

[0027] (2) In a demolding method of the utility model, the two sets of flipping mechanisms are first in the maximum open state. At this time, the distance between the two flipping mechanisms is greater than and as close as possible to the length of the mold cart. In this way, the flipping mechanisms do not need to cross the height of the mold cart and can be directly moved to the two ends of the mold cart. Then, the flipping mechanisms are moved horizontally a very small distance to complete the grabbing operation of the mold cart. Compared with the traditional flipping mechanism that needs to cross the mold cart and then move down, the utility model directly moves horizontally from both ends of the mold cart to clamp, the flipping mechanism has a shorter stroke, takes less time, and can greatly improve work efficiency.

[0037] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0038] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0039] The utility model is further described below in conjunction with specific embodiments.

[0040] refer to Figure 1 , Figure 2 The figure shows the structure of the existing flip lifting device, which usually adopts a straight up and down working mode. That is, the flip lifting device first drives the flip hook to move above the mold car, and then drives the flip hook down to the mold car's lifting ear and grabs the mold car; finally, the flip hook drives the mold car to rotate to realize the flip demolding operation of the mold car.

[0041] In this straight up and down working mode, in order to make the flip hook just engage with the lifting lug after it is lowered, it is necessary to ensure that the distance D1 between the two flip hooks is smaller than the total length of the mold cart (including the lifting lug) D2. In order to prevent the mold cart from blocking the flip hook when it moves above the mold cart and affecting its normal movement, the flip hook needs to be raised to a certain height so that the flip hook can pass over the mold cart. That is, the rising height H2 of the flip hook needs to be greater than the height H1 of the mold cart itself, resulting in a larger moving path of the flip hook.

[0042] Although the above-mentioned flipping method can complete the flipping operation of the mold vehicle, it takes a long time due to its large total stroke. Under the environmental trend of vigorously advocating to improve production efficiency and shorten the single-machine operation time of equipment, this method greatly reduces production efficiency and increases production costs. To this end, the utility model aims to provide a flip lifting device that can effectively shorten the moving stroke of the flip hook and improve work efficiency.

[0043] like Figure 3 As shown, a turning device for a casting mold trolley of this embodiment includes a lifting mechanism 1 and a turning mechanism 2 arranged on the lifting mechanism 1. The lifting mechanism 1 includes a group of lifting columns 11 arranged opposite to each other and a lifting beam 12 located between the two lifting columns 11. Two groups of turning mechanisms 2 are provided, and are respectively located on both sides of the lifting mechanism 1. The two groups of turning mechanisms 2 clamp the two ends of the mold trolley 3 from both sides and drive the mold trolley 3 to turn over.

[0044] It should be noted that the two ends of the mold cart 3 refer to the ends of the mold cart 3 where the lifting ears 31 are provided, that is, the two ends of the mold cart 3 in the length direction.

[0045] refer to Figure 3 , Figure 4 As shown in the figure, as an embodiment of the flipping mechanism 2, the flipping mechanism 2 includes a mounting frame 21 and a flipping part 22 rotatably arranged on the mounting frame 21. The mounting frame 21 is a connecting part between the entire flipping mechanism 2 and the lifting mechanism 1. The flipping part 22 is used to engage the lifting ear 31 on the mold cart 3 to grab the mold cart 3 to facilitate the subsequent flipping and transfer operations.

[0046] In this embodiment, the two flipping parts 22 need to be able to move away from or close to each other to complete the clamping and releasing operations of the mold cart 3. At the same time, the flipping part 22 can also rotate to complete the flipping action of the mold cart 3. The relative movement between the two flipping parts 22 can be the movement of the flipping part 22 itself, for example, the flipping part 22 is connected to an oil cylinder, an air cylinder or an electric push rod to directly drive the flipping part 22 to move. Or the flipping part 22 is driven to move by the mounting frame 21. In this embodiment, the latter movement method is adopted.

[0047] Specifically, as an embodiment of the mounting frame 21, the mounting frame 21 is an inverted L-shaped structure as a whole, which includes a horizontal section and a vertical section connected to each other. The horizontal section of the mounting frame 21 is slidably matched with the lifting beam 12 through a linear guide pair, and the horizontal section is connected to a horizontal driving source 23. The mounting frame 21 is driven by the horizontal driving source 23 to move along the linear guide pair, thereby driving the flip part 22 thereon to move.

[0048] The flipping part 22 is rotatably mounted on the vertical section of the mounting frame 21, and the vertical sections of the two mounting frames 21 are arranged away from each other to increase the space between the two flipping parts 22, so as to facilitate the mold vehicle 3 to move into the space. At the same time, the flipping part 22 is connected to a flipping driving source 24, which drives the flipping part 22 to rotate, thereby driving the mold vehicle 3 to flip.

[0049] The horizontal drive source 23 and the flip drive source 24 can be oil cylinders, air cylinders or electric push rods. The linear guide pair can be a guide rail slider, a guide rod guide sleeve, a guide rod guide groove, etc.

[0050] Specifically in this embodiment, the horizontal driving source 23 and the turning driving source 24 are both oil cylinders. Among them, the oil cylinder used to drive the mounting frame 21 has one end hinged to the bottom of the lifting beam 12, and the other end hinged to the end of the horizontal section of the mounting frame 21. At the same time, a slider 25 is provided at the top of the horizontal section, and a guide rail that slides with the slider 25 is provided at the bottom of the lifting beam 12. Another oil cylinder used to drive the turning part 22 to rotate has one end connected to the connecting shaft on the turning part 22, and the other end connected to the adjustment seat 26 on the mounting frame 21.

[0051] As an embodiment of the flip part 22, the flip part 22 includes a flip plate 221 and a clamping slot 222 arranged on the flip plate 221. The middle position of the flip plate 221 is rotatably connected to the side wall of the mounting frame 21 through a bearing assembly. In order to ensure the stability of the mold cart 3 during the rotation process, two clamping slots 222 are provided, and their cross-sections are polygonal, for example, regular quadrilateral, hexagonal, etc. Similarly, the end of each mold cart 3 is also provided with two lifting ears 31 equipped therewith.

[0052] In the flipping device of a casting mold trolley of the present embodiment, the two flipping mechanisms 2 can move laterally, and the maximum distance D1 when the two flipping mechanisms 2 are opened to each other is greater than the length D2 of the mold trolley 3 (the closer D1 and D2 are, the better, on the premise that the mold trolley can smoothly enter between the two flip plates 221), so that the mold trolley 3 can be grasped and released by retracting or opening the two flipping mechanisms 2; compared with the traditional flipping device, which needs to cross the mold trolley 3 and then move down to complete the grasping of the mold trolley 3, the flipping device of the present embodiment can move laterally and clamp from both ends of the mold trolley 3, which can effectively reduce the moving path of the flipping device, reduce the operating time of a single device, and is conducive to improving work efficiency.

[0053] like Figure 6 As shown, this embodiment also provides a flip demoulding machine, which includes a frame 4, a walking assembly 5 and the above-mentioned flipping device. Among them, the frame 4 serves as the installation base of the entire demoulding machine, and includes a pair of parallel beams, which are supported by pillars and have rails on them.

[0054] The two ends of the walking assembly 5 are slidably arranged on the corresponding crossbeams through a pulley block, and the walking assembly 5 is connected to a driving mechanism for driving the walking assembly 5 to slide along the extension direction of the crossbeam. A guide column extending downward is provided at the bottom of the walking assembly 5, and the lifting column 11 of the flipping device is slidably connected to the corresponding guide column. The lifting column 11 is also connected to a driving mechanism, which drives the lifting column 11 to move vertically along the guide column, thereby driving the entire flipping device to move vertically.

[0055] It should be noted that Figure 6 The Y direction is the extension direction of the beam, the Z direction is the extension direction of the guide column, and the X direction is the extension direction of the lifting beam. At the same time, the above-mentioned driving mechanism can adopt existing technology, such as a structure of a reducer plus a transmission gear, or other structures that can achieve the same function, which will not be introduced one by one here.

[0056] In addition, in order to facilitate the opening and closing of the mold vehicle 3, a mold opening and closing mechanism 6 is provided at the bottom of the lifting beam 12 of the turning device. The mold opening and closing mechanism 6 here is also a prior art and will not be described in detail.

[0057] The method for demoulding using the above-mentioned flip demoulding machine comprises the following steps:

[0058] The mold cart 3 is transported to the predetermined station;

[0059] The walking assembly 5 drives the flipping device to move to the position of the mold vehicle 3; at this time, the two flipping plates 221 of the flipping device are respectively located at the two ends of the mold vehicle 3;

[0060] The horizontal driving source 23 of the flipping device is activated, driving the two flipping plates 221 to move toward each other, so that the slots 222 on the flipping plates 221 are inserted into the ears 31 on the mold cart 3, thereby performing a grabbing action on the mold cart 3;

[0061] After the flip demoulding machine grabs the mold cart 3, the mold opening and closing mechanism 6 opens the side plate of the mold cart 3; then, the flip driving source 24 of the flip device is activated to push the flip plate 221 to flip, thereby realizing the flip demoulding operation of the mold cart 3;

[0062] The driving mechanism is activated to drive the mold trolley 3 to move and lift at the same time, and deliver the mold trolley 3 to the next predetermined workstation.

[0063] In a flip demolding method of the present embodiment, the two sets of flip mechanisms 2 are first in the maximum open state. At this time, the spacing between the two flip mechanisms 2 is greater than and as close as possible to the length of the mold cart 3; in this way, the flip mechanism 2 does not need to cross the height of the mold cart 3, and can be directly moved to the two ends of the mold cart 3; then, the flip mechanism 2 is moved sideways a very small distance at one end to complete the grabbing operation of the mold cart 3; compared with the traditional flip mechanism 2 that needs to cross the mold cart 3 and then move down, the present embodiment directly performs sideways clamping from both ends of the mold cart 3, the flip mechanism 2 has a shorter stroke, takes less time, and can greatly improve work efficiency.

[0064] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
