Description

Modular precast component vertical formwork fabrication equipment Technical Field

[0001] This invention relates to the field of precast component manufacturing, and in particular to a mold-making device for deformable precast components. Background Technology

[0002] Precast components generally come in three configurations: straight, L-shaped, and T-shaped (L-shaped and T-shaped can be collectively referred to as corner types). Correspondingly, their molds are also straight, L-shaped, and T-shaped, respectively. The production methods for precast components can be broadly divided into two types: flat mold production and vertical mold production. Flat mold production involves setting the precast component mold horizontally and then pouring concrete into the mold. Vertical mold production involves transporting the precast component mold to a vertical mold-making platform, where concrete is poured while the precast component mold remains vertical.

[0003] A vertical formwork fabrication platform typically consists of multiple parallel, spaced-apart mold boxes (such as CN114505947A), with precast component molds sandwiched between adjacent mold boxes. Concrete is poured from the top of the precast component molds. However, this type of vertical formwork fabrication platform is often only suitable for fabricating straight precast components and cannot simultaneously meet the fabrication requirements of L-shaped, T-shaped, U-shaped, and other corner-shaped precast components.

[0004] Therefore, this invention is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a mold-making equipment for variable precast components, which can simultaneously meet the production needs of both linear and corner precast components in one set of equipment.

[0006] To address the above problems, embodiments of the present invention provide a mold-making device for deformable precast components, comprising:

[0007] At least two units are used to construct the space for installing prefabricated component molds;

[0008] Of the at least two units, at least one is a movable unit that can be moved to a first position whereby the at least two units form a corner space for installing a corner-shaped prefabricated component mold.

[0009] In the first position, or when the movable unit moves to the second position, the at least two units can also create space for installing the mold for the linear prefabricated component.

[0010] Compared with existing technologies, this invention can meet the production needs of different types of prefabricated components by switching the positions of each unit, including linear, T-shaped, and L-shaped prefabricated components, all of which can be completed by a single set of equipment, thus improving the flexibility and diversity of prefabricated component production.

Detailed Implementation

[0032] The principles and spirit of the invention will now be described with reference to several exemplary embodiments illustrated in the accompanying drawings. It should be understood that these embodiments are described merely to enable those skilled in the art to better understand and implement the invention, and are not intended to limit the scope of the invention in any way.

[0033] Please refer to Figures 1-13. This embodiment of the invention provides a variable precast component mold making device, comprising at least two units for constructing a space for installing precast component molds. At least one of the at least two units is a movable unit, which can be moved to a first position. In the first position, the at least two units construct a corner space for installing a corner-type precast component mold. In the first position, or when the movable unit moves to a second position, the at least two units can also construct a space for installing a straight-type precast component mold. The device further includes a moving guide mechanism, which cooperates with the movable unit to move the movable unit to the first position or the second position under the guidance of the moving guide mechanism.

[0034] The technical solution of the present invention will be described below through some specific embodiments.

[0035] As shown in Figures 1-7, in one embodiment, the manufacturing equipment includes three main parts: a base unit 1, a first mold box unit 2, and a second mold box unit 3. The guiding mechanism includes a first sliding component and a second sliding component, the second sliding component of which can further include a first sub-component and a second sub-component. The first sliding component is connected to the bottom of the first mold box unit 2, driving the first mold box unit 2 to move along a first trajectory that approaches or moves away from the base unit 1. In this embodiment, the first trajectory is defined as longitudinal. The first sub-component drives the second mold box unit 3 to move along a second trajectory that approaches or moves away from the base unit 1, and the second sub-component drives the second mold box unit 3 to move along a third trajectory that approaches or moves away from the first mold box unit 2. In this embodiment, the second trajectory is also longitudinal, so it is parallel to the first trajectory. The third trajectory is defined as transverse, and it is perpendicular to both the second and first trajectories. Thus, by changing the spatial relationship between the first mold box unit 2, the second mold box unit 3, and the base unit 1, different shaped prefabricated component installation spaces can be formed, such as T-shaped, L-shaped, or straight-line types.

[0036] As a more concrete example, the basic unit 1 is roughly rectangular in shape and vertically arranged, thus forming a straight first inner surface 4 on its inner side. A first mold box unit 2 is arranged on both the front and rear sides of the basic unit 1, and a second mold box unit 3 is arranged on each of the left and right sides of the first mold box unit 2. Therefore, in terms of spatial layout, the first mold box unit 2 is closer to the center of the basic unit 1, while the second mold box unit 3 is closer to the sides of the basic unit 1. The first mold box unit 2 is generally a three-dimensional structure with a horizontal cross-section in the shape of a groove, that is, it includes a generally flat cube, whose two sides are bent vertically away from the basic unit 1. In other words, a straight second inner surface 5 is formed in the middle section of the inner surface of the first mold box unit 2, and the sides of the second inner surface 5 are bent vertically away from the basic unit 1 to form a third inner surface 6. The second mold box unit 3 is generally a column with an L-shaped horizontal cross section. Therefore, its inner surface includes a fourth inner surface 7 parallel to the first inner surface 4 and a fifth inner surface 8 formed by bending and extending perpendicularly to the fourth inner surface 7 at the end of the fourth inner surface 7 near the first mold box unit 2 in a direction away from the base unit 1. Thus, the inner surfaces of the first mold box unit 2, the second mold box unit 3 and the base unit 1 have been defined. The positional relationships that can be formed between the various inner surfaces are described below.

[0037] The first position can be further divided into three sub-positions: the first sub-position, the second sub-position, and the third sub-position.

[0038] In the first sub-position, the first mold box unit 2 and the second mold box unit 3 move to the lower position, so that the fourth inner surface 7 fits against the first inner surface 4, and the fifth inner surface 8 and the third inner surface 6 are spaced apart. This allows the first inner surface 4, the second inner surface 5, the third inner surface 6, and the fifth inner surface 8 to form an installation space for the L-shaped precast component mold 9. This method is suitable for the fabrication of precast components with one side longer than the other at a corner. When the first mold box unit 2 has second mold box units 3 on both sides, it can also be applied to the fabrication of a U-shaped precast component mold 38. That is, the U-shaped space is equivalent to the shape of two L-shaped spaces joined together. Therefore, in this embodiment, it should be understood that the L-shaped space also includes the U-shaped space.

[0039] In the second sub-position, an installation space for an L-shaped precast component mold 9 can also be formed. In this case, the second inner surface 5 is in contact with the first inner surface 4, and there is a gap between the third inner surface 6 and the fifth inner surface 8, and a gap between the fourth inner surface 7 and the first inner surface 4. Thus, the first inner surface 4, the third inner surface 6, the fourth inner surface 7 and the fifth inner surface 8 enclose the installation space for the L-shaped precast component mold 9. This method is more suitable for the production of precast components with relatively short lengths on both sides of the corner.

[0040] In the third sub-position, the second inner surface 5 and the first inner surface 4 are spaced apart; the fourth inner surface 7 and the first inner surface 4 are spaced apart; the fifth inner surface 8 and the third inner surface 6 are spaced apart, so that the first inner surface 4, the second inner surface 5, the third inner surface 6, the fourth inner surface 7 and the fifth inner surface 8 form the installation space of the T-shaped prefabricated component mold 10.

[0041] In the second position, the first inner surface 4 and the second inner surface 5 are spaced apart, the fifth inner surface 8 and the third inner surface 6 are fitted together, and the fourth inner surface 7 and the first inner surface 4 are fitted together, thereby forming an installation space for the linear precast component mold 11 between the first inner surface 4 and the second inner surface 5.

[0042] In order to allow the first mold box unit 2 and the second mold box unit 3 to move flexibly to the above-mentioned positions, the first sliding component includes one or more (two in this embodiment) first tracks 12. The first tracks 12 are arranged longitudinally and are provided with first wheel sets 13. The first wheel sets 13 are fixedly connected to the bottom of the first mold box unit 2, so that the first mold box unit 2 can move longitudinally along the first track 12.

[0043] The first sub-component of the second sliding assembly includes one or more second tracks 14, four in this embodiment, two at the bottom of each second mold box unit 3, and second wheel sets 15 on the second tracks 14. The second sub-component includes a base 16 and a moving frame 17. A third wheel set 18 is provided on the base 16, and the third wheel set 18 slides with the moving frame 17. The top of the moving frame 17 is connected to the bottom of the second mold box unit 3, and the bottom of the base 16 is connected to the second wheel set 15. A power device, a hydraulic cylinder 19 in this embodiment, is also provided on the base 16, and the hydraulic cylinder 19 is connected to the moving frame 17. In this way, under the action of the hydraulic cylinder push rod, the moving frame 17 can move laterally along the third wheel set 18, thereby driving the second mold box unit 3 to move laterally. The longitudinal movement of the second mold box unit 3 is accomplished by means of the second wheel set 15 on the second tracks 14, thereby realizing the fitting and separation of the second mold box unit 3 with the first mold box unit 2, or with the base unit 1, so as to form the aforementioned L-shaped, T-shaped, or straight space.

[0044] When the first mold box unit 2 and the second mold box unit 3 move to a predetermined position relative to the base unit 1, the first mold box unit 2 and the second mold box unit 3 are connected by a first fastening mechanism; the base unit 1 and the second mold box unit 3 are connected by a second fastening mechanism. The first mold box units 2 and the second mold box units 3 at the corresponding front and rear positions are connected by a third fastening mechanism.

[0045] In this embodiment, the second fastening mechanism includes a first fixing seat 20 disposed on the side end of the second mold box unit 3 and a second fixing seat 21 disposed on the side end of the base unit 1. The first fixing seat 20 has a strip-shaped connecting groove 23, and the second fixing seat 21 has a pivotable connecting fixing rod 22. After the fixing rod 22 is rotated, it is inserted into the connecting groove 23. The end of the fixing rod 22 has a thread (such as using a lead screw as the fixing rod 22), so it can be fixed by a nut (the same below).

[0046] In other embodiments, referring to FIG9, the second fastening mechanism may also include a groove 24 directly constructed on the first mold box unit 2 and the second mold box unit 3, and the fixing rod is directly inserted into the groove 24 to achieve connection.

[0047] The first fastening mechanism includes a third fixing seat 25 and a fourth fixing seat 26 respectively disposed on the front end face of the first mold box unit 2 and the front end face of the second mold box unit 3. Both the third fixing seat 25 and the fourth fixing seat 26 are provided with strip-shaped connecting grooves 23. The end of the fixing rod 22 is threaded, inserted into the connecting groove 23 and fixed by a nut, thereby fastening the first mold box unit 2 and the second mold box unit 3.

[0048] The third fastening mechanism includes a fifth fixing seat 27 located on the upper end of the first mold box unit 2 and the second mold box unit 3. The fifth fixing seat 27 has a strip-shaped connecting groove 23. The fixing rod 22 is inserted into the connecting groove 23 and fixed by a nut to achieve fastening between the first mold box unit 2 and the second mold box unit 3 at the corresponding front and rear sides.

[0049] The reason for using the elongated connecting groove 23 is that the movable unit in this embodiment moves very flexibly, so the end faces of the units may not be aligned. The elongated connecting groove 23 provides more ample connecting space in its length direction, making it easier to insert the fixing rod into the appropriate position to achieve a tight connection between two adjacent units.

[0050] Referring to Figures 10-13, in another embodiment, the variable precast component vertical mold making equipment includes a base unit 1 and a third mold box unit 28. Unlike the previous embodiment, the base unit 1 has a straight sixth inner surface 29 and a seventh inner surface 30 formed by vertical bending and extending at the end of the sixth inner surface 29.

[0051] There are two third mold box units, both generally L-shaped and spaced apart. The inner surface of the third mold box unit 28 includes a straight eighth inner surface 31. The side of the eighth inner surface 31 bends and extends perpendicularly to the eighth inner surface 31 in a direction away from the base unit 1 to form a ninth inner surface 32. In the first position, the eighth inner surface 31 is spaced apart from the sixth inner surface 29, and the ninth inner surface 32 is spaced apart from the seventh inner surface 30, thus forming an installation space for the L-shaped precast component mold. In the second position, the straight segments of the two third mold box units 28 move towards each other and dock together, thus forming an installation space for the straight precast component mold (not shown in the figure).

[0052] To enable the third mold box unit 28 to move as described above, the movement guiding mechanism includes: a third sliding component connected to the bottom of the third mold box unit 28; the third sliding component includes a third sub-component and a fourth sub-component; the third sub-component drives the third mold box unit to move laterally, and the fourth sub-component drives the third mold box unit to move longitudinally. As an example, the third sub-component includes: one or more third tracks 33; a fourth wheel set 34 is provided on the third track 33; the fourth sub-component includes: a fifth wheel set 35 and a moving frame 17 adapted to the fifth wheel set 35; the moving frame is connected to a power device (such as a hydraulic cylinder 19); driven by the power device, the moving frame 17 can move laterally using the fifth wheel set 35; the bottom of the fifth wheel set 35 is mounted on a base 16, which is connected to the fourth wheel set 34; the hydraulic cylinder 19 is also mounted on the base 16. This achieves both lateral and longitudinal movement of the third mold box unit 28.

[0053] The base unit 1 and the third mold box unit 28 are connected by a fourth fastening mechanism; the fourth fastening mechanism includes a sixth fixing seat 36 on the side end face of the third mold box unit 28 and the base unit 1, and a strip-shaped connecting groove 23 is constructed on the sixth fixing seat 36; the fixing rod 22 is inserted into the connecting groove 23 and fixed by a nut to achieve the fastening of the third mold box unit 28 and the base unit 1.

[0054] In this embodiment, a third mold box unit 28 is provided on both the front and rear sides of the base unit 1, and the third mold box units 28 corresponding to the front and rear sides are connected by a fifth fastening mechanism. The fifth fastening mechanism includes a seventh fixing seat 37 provided on the upper end of the base unit 1 and the third mold box unit 28, and a strip-shaped connecting groove 23 is constructed on the seventh fixing seat 37. The fixing rod 22 is inserted into the connecting groove 23 and fixed by a nut to achieve fastening between the third mold box units 28 corresponding to the front and rear sides.

[0055] Referring to Figures 14-20, in some embodiments, the movable frame 17 of the base 16 is further provided with several adjusting shafts, and the adjusting shafts are provided with connecting frames, which are then connected to the second mold box unit 3 or the third mold box unit 28 through the connecting frames 40. The adjusting shafts can allow the first mold box unit 3 or the third mold box unit 28 to move in an arc in the horizontal direction. The purpose of this is that when there is a slight error in the movement position of the first mold box unit 3 and the third mold box unit 28, resulting in problems such as loose connection or gaps between mold box units or between mold box units and molds, the position of the first mold box unit 3 or the third mold box unit 28 can be finely adjusted in the horizontal direction using the adjusting shafts, thereby solving the above problems. In some embodiments, the adjusting shaft is a bullseye shaft 42, with the bottom end of the bullseye shaft 42 connected to the movable frame 17 and the spherical ball bearing in the middle connected to the connecting frame 40 above. In other embodiments, the adjustment shaft is an eccentric shaft 41, including a first shaft body 410, a rotating part 411 disposed above the first shaft body 410, and a second shaft body 412 disposed above the rotating part 411. The first shaft body 410 and the second shaft body 412 are eccentrically arranged relative to the center of the rotating part 411 and are far apart from each other. In this way, the second mold box unit 3 or the third mold box unit 28 can move along an arc in the horizontal direction by means of the bullseye shaft 42 or the eccentric shaft 41.

[0056] This article uses specific examples to illustrate the inventive concept in detail. The description of the above embodiments is only for the purpose of helping to understand the core idea of ​​the present invention. It should be noted that any obvious modifications, equivalent substitutions or other improvements made by those skilled in the art without departing from the inventive concept should be included within the protection scope of the present invention.
