Description

Technical Field

[0001] The invention relates to the technical field of prefabricated components, in particular to a prefabricated component vertical mold production device. Background Art

[0002] Prefabricated components are made in factories using molds. A common prefabricated component is a concrete wall. After the mold is set up in the factory, concrete is poured into the mold. After the concrete solidifies, the mold is removed to obtain a prefabricated wall.

[0003] The production methods of prefabricated components include flat molds and vertical molds. Flat molds refer to molds placed horizontally, and vertical molds refer to molds placed vertically. The inventor has invented a prefabricated wall mold that can be used for both flat mold production and vertical mold production. The prefabricated wall mold includes a generally rectangular mold frame, and a core mold is arranged in the mold frame to construct the shape of the interior of the prefabricated wall.

[0004] However, the removal of the core mold usually still requires manual removal, which consumes manpower and time and has low production efficiency.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The object of the present invention is to provide a prefabricated component mold production device, which can assemble and disassemble the core mold of the prefabricated component mold in an automated manner.

[0007] To solve the above problems, an embodiment of the present invention provides a prefabricated component mold production device, including at least one vertically arranged core mold, the side of the core mold is provided with a track for the core mold to move up and down, and the bottom of the core mold is connected to a mechanism that can provide power for the up and down movement.

[0008] Furthermore, the device also includes a bracket, on which the core mold, the track and the power providing mechanism are installed; the bracket is equipped with a walking mechanism that drives it to move in the horizontal direction.

[0009] Furthermore, the power providing mechanism includes a driving unit and a transmission unit, and the driving unit is connected to the core mold through the transmission unit.

[0010] Furthermore, the driving unit includes at least one oil cylinder installed on the bracket, and the push rod of the oil cylinder is arranged downward; the transmission unit includes a through shaft connected to the lower end of the push rod; the side end of the core mold extends downward to form a connecting plate, and a core mold hole is opened at the bottom of the connecting plate. The through shaft passes through the core mold hole to transmit power from the oil cylinder to the core mold.

[0011] Furthermore, a transversely penetrating cylinder hole is opened on the cylinder seat of the cylinder, and the cylinder hole is connected to the bracket through a connecting shaft; a support plate is provided on the top of the cylinder seat; when the downward force of the push rod of the cylinder is not sufficient to push the through shaft downward, the cylinder hole provides space for the cylinder to move upward, so that the support plate can provide an upward support force.

[0012] Furthermore, guide plates fitted thereto are provided on both sides of the core mold, and tracks for the core mold to move up and down are constructed on the guide plates; guide shafts slidably fitted with the tracks are provided on both sides of the core mold.

[0013] Furthermore, the bottom end of the track extends horizontally and leads to the outside of the guide plate. A removable baffle is provided on the track. After the baffle is removed, the core mold can be removed along the track. A round tube passes through the connecting plate. The round tube is composed of two upper and lower semicircular tubes that are detachably spliced ​​together. The through shaft passes through the round tube. When the semicircular tube located below is removed, the connection between the through shaft and the core mold is released.

[0014] Furthermore, the edges of the upper and lower semicircular tubes are extended for a distance, and the extended parts are connected with adjusting bolts. By rotating the adjusting bolts, the distance between the upper and lower semicircular tubes can be changed, thereby changing the distance between the through shaft and the inner edge of the lower semicircular tube.

[0015] Furthermore, the height of the lower edge of the core mold hole is distributed in a stepped manner, so that the lower edge of the core mold hole close to the through axis is subjected to force first, and the lower edge of the core mold hole far from the through axis is subjected to force later.

[0016] Furthermore, a transverse fixing component is installed on the front side and / or the rear side of the connecting plate to straighten the up and down movement of the core mold.

[0017] Furthermore, the fixing component is provided with a long hole for installing a bolt, and the fixing position of the bolt can be adjusted along the long hole.

[0018] A working method of the above-mentioned prefabricated component mold production device comprises:

[0019] When assembling the core mold, the power-providing mechanism is controlled to move the core mold upward and enter the mold frame on the mold table;

[0020] Concrete is poured into the mold frame. After the concrete solidifies or semi-solidifies, the power-providing mechanism is controlled to move the core mold downward and be drawn out of the mold frame, thereby completing the removal of the core mold.

[0021] Furthermore, before assembling the core mold, the method also includes a step of transporting the core mold to below the mold platform.

[0022] Further, after the core mold is removed, the core mold is transported to a cleaning area for cleaning so that it can be put into use again.

[0023] Compared with the prior art, the present invention has the following beneficial effects: in a mold system with a vertical mold arrangement, the core mold can be automatically assembled and disassembled, and the production effect is high. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The principle and spirit of the present invention will be described below with reference to several exemplary embodiments shown in the accompanying drawings. It should be understood that these embodiments are described only to enable those skilled in the art to better understand and implement the present invention, and are not intended to limit the scope of the present invention in any way.

[0038] Please refer to Figure 1-2 , an embodiment of the present invention provides a mold assembly and disassembly device for a prefabricated component. The device is used to dismantle the core mold 2 of the prefabricated component mold. In an embodiment of the present invention, the prefabricated component mold is used to make a prefabricated wall, that is, a prefabricated wall mold. The prefabricated wall mold includes a substantially rectangular mold frame 1, which is surrounded by four side molds to form a concrete pouring space for the prefabricated wall. A core mold 2 is provided in the mold frame 1 to construct the shape of the interior of the prefabricated component. For example, in this embodiment, the core mold 2 is a mold box that is substantially in the shape of a square box, and a plurality of them are arranged at intervals along the length direction of the mold frame 1. After the concrete is poured into the mold frame 1, the gap between the core mold 2 and the mold frame 1 is filled. After the concrete is solidified or semi-solidified, the core mold 2 is pulled out of the mold frame 1, leaving a cavity corresponding to the shape of the core mold 2 inside the concrete component. In this embodiment, the cavity left by the core mold 2 is used for on-site pouring of concrete. The entire mold frame 1 is placed on a vertically set mold platform 3.

[0039] like Figure 4 As shown, an opening 102 corresponding to the size and shape of the core mold 2 is provided on the lower mold 101 of the mold frame 1. When assembling the mold, the core mold 2 enters the inner side of the mold frame 1 from the opening 102. When disassembling the mold, the core mold 2 is pulled downward from the inner side of the mold frame 1. The embodiment of the present invention provides a set of control mechanisms for automatically disassembling and assembling the core mold 2.

[0040] The control mechanism includes a driving device and a transmission mechanism. The driving device is connected to the core mold 2 through the transmission mechanism to control the up and down movement of the core mold 2.

[0041] The driving device can be in various forms, such as oil cylinder 4, air cylinder, motor, etc. Figure 2 As shown, in this embodiment, the push rod 401 is directed downward to the oil cylinder 4. Both sides of each core mold 2 extend downward to form a connecting plate 201, and a long core mold hole 202 is provided at the bottom of the connecting plate 201. The transmission mechanism mainly includes a through shaft 5. The through shaft 5 passes through the long holes 202 of each core mold, connecting each core mold 2 in series. The push rod 401 of the oil cylinder 4 is connected to the end of the through shaft 5 to transmit the action and force to each core mold 2. When the push rod 401 of the oil cylinder 4 is set downward, the main part of the oil cylinder 4 can be installed on the side close to the mold platform 3, saving the occupied space in the vertical direction. In this embodiment, a group of oil cylinders 4 are connected to the through shaft 5 at a certain distance, which enhances the driving force, and the force uniformity of the through shaft 5 is also better. The number of oil cylinders 4 can be flexibly adjusted according to actual conditions.

[0042] When assembling the core mold 2, the core mold 2 is aligned with the opening 102 of the lower mold 101, and the push rod 401 of the oil cylinder 4 is contracted, driving the through shaft 5 to move upward, against the upper edge of the core mold long hole 202, and lifting the core mold 2 upward, passing through the opening 102 and entering the inside of the mold frame 1. Then, concrete is poured into the mold frame 1.

[0043] When removing the mold, the push rod 401 of the oil cylinder 4 extends downward, driving the through shaft 5 to move downward, so that the through shaft 5 contacts the lower edge of the core mold long hole 202. In an ideal situation, the through shaft 5 applies a force to the lower edge of the core mold long hole 202, pulling the entire core mold 2 out of the concrete wall. However, in reality, the concrete has solidified at this time, and the friction between the core mold 2 and the concrete is very large, so the through shaft 5 cannot pull the core mold 2.

[0044] like Figure 3 As shown, in order to solve this difficulty, the inventors have opened a horizontally penetrating long cylinder hole 402 on the cylinder seat of the oil cylinder 4, and a supporting top plate 6 is arranged on the top of the cylinder seat. Because of the existence of the long cylinder hole 402, the entire oil cylinder 4 has a certain space for movement in the vertical direction. When the through shaft 5 cannot pull the core mold 2 downward, the push rod 401 of the oil cylinder 4 will no longer move downward, and the entire oil cylinder 4 will be subjected to the reverse force transmitted by the through shaft 5. At this time, the push rod 401 of the oil cylinder 4 continues to extend, and the entire oil cylinder 4 will move upward under the reverse force. The distance that the oil cylinder 4 can move upward is roughly equal to the hole spacing of the long cylinder hole 402. Finally, the supporting top plate 6 will support the lower side mold 101 of the mold and exert an upward supporting force.

[0045] At this time, the force state of the demoulding system has changed, and the upper and lower ends of the oil cylinder 4 apply force to the lower mold 101 and the core mold 2 of the mold respectively. The inner side of the lower edge of the core mold long hole 202 is pushed downward by the through shaft 5. On the other hand, the bottom surface of the lower mold 101 is pushed upward by the supporting top plate 6, thus forming a two-way force state of "upward push and downward push". Compared with the state of only the through shaft 5 pulling hard, it is easier to separate the concrete from the core mold 2, reducing the difficulty of demoulding.

[0046] The long hole 402 of the oil cylinder may also adopt other shapes, such as a round hole, etc., as long as the hole diameter and shape can leave a certain amount of movable space for the oil cylinder 4 as a whole.

[0047] During the up and down movement of the core mold 2, shaking and tilting may occur, resulting in the core mold 2 being unable to smoothly enter and exit the opening 102 of the lower mold 101. In this embodiment, a guide plate 7 is provided on the outside of the connecting plate 201 of the core mold 2, and the two are fitted together. A guide plate slide rail 701 is vertically provided on the guide plate 7, and guide shafts 8 are provided on both sides of the core mold 2 to slide with the guide plate slide rail 701. When the core mold 2 moves up and down, the guide plates 7 on both sides play a role in straightening the movement trajectory, so that the core mold 2 can smoothly enter and exit the mold frame 1.

[0048] The front and rear sides of the connecting plate 201 can be laterally mounted with fixing components, which can be in the form of iron plates, channel steels 9, etc. Figure 8 As shown, the fixing member in this embodiment is a horizontal channel steel 9, and the bottom surface of the channel steel 9 is supported on the connecting plate 201 or the guide plate 7 through the pad 10. A mounting hole 901 is also provided on the bottom surface of the channel steel 9 for mounting bolts 11. Sometimes, the position and spacing of each core mold 2 are not fixed. For this reason, the mounting hole 901 can be designed as a long hole to leave a certain degree of flexibility for the fixing position of the core mold 2. In addition, the channel steel 9 can also play a role in straightening the vertical movement of the core mold 2.

[0049] A bottom bracket 12 is provided below the die table 3. The bottom bracket 12 includes a plurality of groups of support plates 121 arranged at intervals in the horizontal direction, each group having two plates, and the number can of course be flexibly adjusted. A slide rail 122 is vertically provided at the middle and lower part of the support plate 121, and the through shaft 5 passes through the slide rail 122 and slidably cooperates with the slide rail 122.

[0050] The oil cylinder 4 is located between the two side support plates 121, and the cylinder seat of the oil cylinder 4 is connected to the top of the support plate 121 through a connecting shaft 123. When the oil cylinder 4 as a whole needs to move in the vertical direction, the aforementioned oil cylinder long hole 402 can be opened on the support plate 121.

[0051] Supporting facilities of the driving device, such as a gas station, a power station, a control console, etc., can also be arranged on the bottom bracket 12. Of course, these supporting facilities can also be arranged at other suitable positions.

[0052] The more core molds 2 there are in the prefabricated wall, the greater the friction between the core molds 2 and the concrete, and the more difficult it is to remove. The embodiment of the present invention provides a stepped force-bearing structure. During the demolding process, part of the core molds 2 are subjected to force first, and after they are removed a short distance, the other part of the core molds 2 are subjected to force. This is because the core molds 2 removed first can reduce the overall friction of each core mold 2, thereby dispersing the force conditions of each core mold 2. Avoid the situation where the wall core molds 2 cannot be removed due to excessive friction. This stepped force-bearing structure can be implemented in a variety of ways, which are introduced below.

[0053] In one embodiment, the height of the lower edge of the core mold long hole 202 is distributed in a stepped manner. For example, starting from one side, the height of the lower edge of each core mold long hole 202 decreases in sequence (not shown in the figure). When removing the mold, the lower edge close to the through shaft 5 is subjected to force first, and the lower edge far from the through shaft 5 is subjected to force later. When the through shaft 5 descends, it first contacts the core mold long hole 202 with the highest lower edge. After it is pulled out a short distance, the friction force will be greatly reduced, and the remaining core molds 2 will be smoothly pulled out one after another.

[0054] In another embodiment, Figure 5 , 6 As shown, a round tube 13 is passed through between the connecting plates 201 on both sides of each core mold 2, and the round tube 13 is spliced ​​by two upper and lower semicircular tubes 131, and the through shaft 5 passes through each round tube 13. After removing the round tube 13, the core mold 2 can be released from the connection state with the through shaft 5. If a certain core mold 2 is not needed, or a certain core mold 2 needs to be replaced or repaired, it can be removed separately. The edges of the two semicircular tubes 131 extend out a section, and the protruding part is connected with an adjusting bolt 14. By adjusting the bolt 14, the distance between the upper and lower semicircular tubes 131 can be changed. The closer the distance is, the higher the lower edge of the whole round tube 13 is, and the closer it is to the through shaft 5, and vice versa. By adjusting the distance with the adjusting bolt 14, a stepped force structure can also be formed.

[0055] As mentioned above, in some cases, there may be a situation where a certain core mold 2 is not needed, or a certain core mold 2 needs to be replaced or repaired. If the through shaft 5 is removed as a whole, the connection between all core molds 2 and the through shaft 5 can be released, but this is very time-consuming. Therefore, the design of splicing two semicircular tubes described above can be adopted to release the connection between a single core mold 2 and the through shaft 5. On the other hand, the bottom of the guide plate 7 slideway of the guide plate 7 on both sides of the core mold 2 extends horizontally and eventually leads to the outside of the guide plate 7. A detachable baffle 15 is also provided on the horizontal extension section 702. When a certain core mold 2 needs to be removed, the baffle 15 is removed, and the connecting shaft of the core mold 2 is disengaged along the guide plate 7 track.

[0056] In another embodiment, Figure 7As shown, the core mold long hole 202 at the bottom of the connecting plate 201 is a split structure, and the upper and lower parts are detachably connected by a connecting buckle 16. When a mold needs to be removed, the bottom part of the connecting plate 201 is removed to release the connection between the core mold 2 and the through shaft 5, and the core mold 2 can be removed.

[0057] The inventors found in their research that if a set of core molds 2 is only used to make one prefabricated component, the work efficiency is relatively low, so the core molds 2 need to be repeatedly used. For this reason, the inventors designed a mechanism that allows the core mold 2 to switch between multiple mold platforms 3. Traveling tracks 17 are placed on both sides of the bottom bracket 12, and the two sides of the bottom bracket 12 cooperate with the traveling tracks 17 through pulleys 18. When assembling the core mold 2, the bottom bracket 12 is transported to the bottom of the mold platform 3 together with the core mold 2 by using the traveling tracks 17, and the oil cylinder 4 is started to complete the assembly action. When disassembling the mold, after the core mold 2 is separated from the mold frame 1, the traveling tracks 17 are used again to transport the core mold 2 to the cleaning area, and after cleaning, it is transported to other mold platforms 3 to make prefabricated components. In other embodiments, the traveling tracks 17 can also be arranged horizontally (such as Fig. 9 As shown in FIG. 1 , the pulley 18 is located at the bottom of the bottom bracket 12, and accordingly, the bottom bracket 12 moves in the lateral direction. The movement of the bottom bracket 12 can be controlled by various driving devices, such as an oil cylinder 4, an air cylinder, a motor, etc. These driving devices themselves are relatively common and will not be described in detail here.

[0058] The device in this embodiment can be used alone or in combination. The direction of the combination can be horizontal (such as Fig.10 When multiple devices are combined together, a matrix of disassembly and assembly of the core mold 2 is formed (as shown in FIG. Fig.11 As shown), multiple walls can be disassembled and assembled at the same time (as shown Fig.12 shown).

[0059] The entire device occupies a relatively large space vertically. In order to save space above the ground, in this embodiment, a pit can be excavated below the working area of ​​the device, and the cylinder 4, bottom bracket 12 and other mechanisms located below the mold platform 3 can be placed in the pit in whole or in part, saving space on the surface.

[0060] The device in this embodiment can be fully automated. For example, the movement of the bottom bracket 12 and the disassembly and assembly of the core mold 2 can be completed by configuring corresponding drive equipment and control systems, which greatly improves production efficiency.

[0061] The invention concept is described in detail using specific examples herein, and the description of the above embodiments is only used to help understand the core idea of ​​the invention. It should be pointed out that any obvious modification, equivalent substitution or other improvement made by a person of ordinary skill in the art without departing from the invention concept should be included in the protection scope of the present invention.
