Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated components, in particular to a fully automatic mold erecting, supporting and withdrawing core mold device and a working method thereof. Background Art

[0002] Precast components are manufactured in a factory using molds. A common precast component is a concrete wall. After the molds are set up in the factory, concrete is poured into the molds. After the concrete solidifies, the molds are removed to create the precast wall.

[0003] Prefabricated components are produced using two methods: flat molds and vertical molds. Flat molds are horizontally positioned, while vertical molds are vertically positioned. The inventors have previously invented a prefabricated wall mold that can be used for both flat and vertical mold production. This prefabricated wall mold comprises a generally rectangular mold frame within which a core mold is positioned to construct the interior shape 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] The inventor previously invented a prefabricated component mold production device, described in Chinese patent publication CN111531688A. It includes at least one vertically mounted core mold, a mold base fixedly connected to a mechanism for installing and removing the core mold, a drive unit comprising at least one oil cylinder mounted on a bracket, a push rod of the oil cylinder positioned downwardly, a transmission unit comprising a through-shaft connected to the lower end of the push rod, and a connecting plate extending downward from the side of the core mold, the bottom of which is rotatably connected to the through-shaft. This production device suffers from the following drawbacks:

[0006] First, the connecting plates of the core molds for removal are connected by a through-axis and can only move together. If one set of core molds fails to be removed, for example, the core mold is too tightly bonded to the concrete and cannot be successfully pulled out, the removal of the other sets of core molds will be affected. Although CN111531688A has a corresponding stepped structure (see paragraphs 0038-0039 of the specification of CN111531688A), this makes the bottom structure of the mold removal mechanism complicated.

[0007] Second, the cast-in-place cavities at the bottom of precast components are formed by core molds, and many precast components have varying numbers, positions, and spacing of these cavities. However, in CN111531688A, the spacing and positions of each set of core molds are fixed, as is the overall number of core molds. Therefore, only this type of precast component can be produced. If the number, position, or spacing of the cast-in-place cavities at the bottom of the precast component is adjusted on the production line, this production device will not be flexible.

[0008] In view of this, the present invention is proposed. Summary of the Invention

[0009] The purpose of the present invention is to provide a fully automatic mold support and core mold extraction equipment, which can clean the core mold at the original work station and can also automatically disassemble the core mold. Each core mold can be disassembled independently, and a variety of prefabricated components with different lateral positions, intervals, and quantities of the bottom cast-in-place cavity can be produced.

[0010] To solve the above problems, an embodiment of the present invention provides a prefabricated component mold production device, comprising a mold body and a base frame, wherein a plurality of core mold support frames are provided on the base frame, and the core molds are mounted on the core mold support frames;

[0011] The base frame includes a crossbeam, and the upper end and / or lower end of each group of the core mold support frames are slidably matched with the crossbeam through a first sliding connection member. The first sliding connection member is adjusted based on the core mold spacing so that the core mold support frames are moved to the corresponding positions and then fixed to the crossbeam with a top screw;

[0012] The core mold support frame includes a back plate, which is located on the side of the crossbeam and connected to the fixing component;

[0013] The bottom of the core mold is connected to the support assembly, and the support assembly includes a second sliding connection and a main shaft. The core mold can rotate around the main shaft to generate an inclination, and the second sliding connection and the side edge of the back plate are slidably matched; the side of the back plate is provided with an inclined reserved groove, so that the second sliding connection is separated from the side edge of the back plate when it moves to the inclined reserved groove; the bottom of the main shaft is connected to a first power device that drives the core mold to move up and down along the back plate.

[0014] Furthermore, the support assembly also includes a first connecting plate, a second connecting plate and a third connecting plate arranged in sequence from the inside to the outside, the first connecting plate is connected to the bottom end of the core mold, the second sliding connection is arranged on the third connecting plate, the second connecting plate can be adjusted vertically and is clamped and fixed by the first connecting plate and the third connecting plate after being adjusted to the specified position; the main shaft is horizontally passed through the second connecting plate.

[0015] Furthermore, a slope is constructed on one side of the bottom end of the second connecting plate close to the back plate, so that when the core mold is tilted along the main axis, the slope abuts against the back plate.

[0016] Furthermore, a through hole is provided at the lower portion of the back plate, and the second power device is connected to the inclined force transmission frame through the through hole; an inclined transmission rod is provided on the inner side of the lower portion of the second connecting plate, so that after the core mold descends along the back plate, the inclined transmission rod can fall into the inclined force transmission frame, and the core mold is tilted under the drive of the second power device.

[0017] Furthermore, a first limit plate is provided on the inner side of the inclined reserved groove, and a second limit plate is provided on the outer edge of the back plate below the notch, so that the second connecting plate can move between the first limit plate and the second limit plate; a third limit plate is also horizontally arranged on the back side, so that the inclined force transmission frame can fall on the third limit plate.

[0018] Furthermore, a distance is reserved between the back plate and the fixing component for the second sliding connection member to pass through, so that the second sliding connection member can move to above the crossbeam.

[0019] The embodiment of the present invention further provides a working method of the above-mentioned fully automatic mold support and core mold extraction device, comprising the following steps:

[0020] Left and right spacing adjustment: adjust the distance between each group of core mold support frames;

[0021] Supporting the mold upward: controlling the core mold support frame to rise so that the core mold enters the mold frame of the prefabricated component;

[0022] Pulling the core mold downward: After the concrete in the precast component mold frame solidifies or semi-solidifies, the core mold support frame is controlled to descend and the core mold is pulled out;

[0023] Tilting the core mold: controlling the core mold to tilt forward and clean the core mold;

[0024] Return formwork: control the return of the core formwork and repeat the upward formwork action.

[0025] Compared with the prior art, the present invention has the following beneficial effects: in a mold system with a vertical mold setting, the core mold can be assembled and disassembled fully automatically, with high production efficiency, and the core mold can be cleaned at the original work station. At the same time, the horizontal position, spacing, and number of each core mold can be flexibly adjusted to meet the production requirements of prefabricated components with different types of cast-in-place cavities at the bottom; and since each core mold support frame is independent and can be replaced individually, there is no need to replace the entire set of equipment because a set of core mold support frames is damaged, and the supporting and demolding of each core mold are independent actions, so there is no need to worry about a set of supporting and demolding mechanisms malfunctioning, resulting in the entire core mold being unable to support or extract the mold.

DETAILED DESCRIPTION

[0042] The principles 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.

[0043] Please refer to Figure 1-2 The present invention provides a fully automatic mold erecting and core mold extraction device, comprising a mold erecting body, which includes a mold base 1 on which a mold frame 2 is vertically placed. The mold frame 2 is generally rectangular and is formed by four side molds. The bottom side mold has several openings for the core mold 3 to enter.

[0044] The mechanism for installing and removing the core mold 3 is fixed to the lower part of the mold platform 1. Under the operation of this mechanism, the core mold 33 can be assembled into the mold frame 2, and the bonding force between the core mold 33 and the concrete can be removed after the concrete in the mold frame 2 solidifies, or further, the core mold 3 can be pulled out from the mold frame 2.

[0045] Combine Figure 1-3 The mechanism for installing and removing the core mold 3 includes a basic frame 4, which includes two upper and lower crossbeams 5 and left and right columns 6. Multiple groups of core mold support frames 10 are horizontally arranged on the basic frame 4, and each group of core mold support frames 10 is installed with a core mold 3.

[0046] Further integration Figure 4-6The upper and lower ends of each set of core mold support frames 10 slide in conjunction with the crossbeam 5 via a first sliding connector. The first sliding connector includes a fixing component that secures the core mold support frame 10 to the crossbeam 5 after it has been moved to a designated position. Taking the fixing component and first sliding connector located at the upper crossbeam 5 as an example, the first sliding connector includes a generally square slideway 7 that slides in conjunction with the crossbeam 5. The slideway 7 has two wheels 29 mounted on the inner side of the crossbeam 5, which can move along the crossbeam 5, thereby driving the core mold support frame 10 to move laterally. The fixing component is a top screw, specifically, a plurality of first bolts 8 connected to the side of the slideway 7 away from the core mold 3. These control components allow the slideway 7 to drive the core mold support frame 10 to move left and right along the crossbeam 5. After adjusting to the appropriate position, the two upper sets of first bolts 8 secure the two wheels 29 on the inner side of the slideway 7, while the two lower sets of second bolts 9 secure the crossbeam 5, thereby fixing the core mold support frame 10 relative to the crossbeam 5.

[0047] Combine Figure 7-12 The core mold support frame 10 includes a back plate 11, which is located on the side of the cross beam 5 and is connected to the slide 7. The bottom of the core mold 3 is connected to the support assembly, and the support assembly includes a second sliding connection and a main shaft 12. The core mold 3 can rotate around the main shaft 12 and thus tilt. The second sliding connection and the side edge of the back plate 11 slide together; an inclined reserved groove 13 is provided on the side of the back plate 11, so that the second sliding connection is separated from the side edge of the back plate 11 when it moves to the inclined reserved groove 13; a first power device 14 is connected below the main shaft 12 to drive the core mold 3 to move up and down along the back plate 11.

[0048] In this embodiment, the support assembly includes two groups of first connecting plates 15, two groups of second connecting plates 16 and two groups of third connecting plates 17 arranged in sequence from the inside to the outside (from the middle to both sides) below the core mold 3. The first connecting plate 15 is directly connected to the bottom end of the core mold 3, and the second sliding connection is a pair of vertically arranged cylindrical sliders 18, which are arranged on the inner side of the rear end of the third connecting plate 17. The sliders 18 and the side edges of the back plate 11 are slidably matched, and the side edges of the back plate 11 are used as slideways for the up and down movement of the core mold 3. After the slider 18 moves to the inclined feeding groove, the sliding fit between the slider and the back plate 11 is released. At this time, the tilting action of the core mold 3 will not be stuck because the slider 18 is restricted by the back plate 11. In some embodiments, the length of the slider 18 located on the inner side of the back plate 11 is greater than the length of the slider 18 located on the outer side of the back plate 11. This allows the upper portion of the slider 18 located on the inner side of the back plate 11 to remain in contact with the back plate 11 when the slider 18 located on the outer side of the back plate 11 moves to the tilting reserved groove 13. This has the advantage that when the core mold 3 is reset from the tilted state, the slider 18 located on the inner side can be in close contact with the back plate 11, acting as a position limiter and ensuring verticality. In this embodiment, the length of the portion of the third connecting plate 17 corresponding to the inner slider 18 is also increased accordingly.

[0049] The second connecting plate 16 can be adjusted vertically and, after being adjusted to a desired position, is clamped and secured by the first connecting plate 15 and the third connecting plate 17. This allows the second connecting plate 16 to flexibly adjust the height of the core mold 3 to accommodate different core molds 3 and prefabricated components. In this embodiment, the first connecting plate 15, the second connecting plate 16, and the third connecting plate 17 are secured together by a third bolt 19 that penetrates the three connecting plates.

[0050] The main shaft 12 is transversely interposed between two sets of second connecting plates 16. For example, the second connecting plates 16 and the main shaft 12 are rotatably connected, allowing the second connecting plates 16 to rotate relative to the main shaft 12, thereby tilting the core mold 3. The first power unit 14, connected below the main shaft 12, can be a cylinder with an upward-pointing push rod. When the cylinder push rod moves downward, it controls the downward movement of the core mold support frame 10 and the core mold 3, completing the extraction operation to extract the core mold 3 from the mold frame. When the cylinder push rod moves upward, it completes the support operation to insert the core mold 3 into the mold frame.

[0051] A through-hole is provided at the bottom of the back plate 11, through which the second power unit 20 (such as a hydraulic cylinder capable of pushing and pulling forward and backward) is connected to the tilting force transmission frame 21. The tilting force transmission frame 21 includes a pair of vertically arranged U-shaped notches 22. A tilting transmission rod 28 is provided on the inner side of the lower portion of the second connecting plate 16. This allows the core mold 3 to descend along the back plate 11, allowing the tilting transmission rod 28 to fall into the U-shaped notch 22 of the tilting force transmission frame 21 and tilt the core mold 3 under the drive of the second power unit 20. As the core mold 3 rises, the U-shaped notch 22 acts as a slide rail. When the core mold 3 is not fully raised, the slider 18 on the inner side of the back plate 11 engages with the back plate 11, providing a fixed position throughout the entire process.

[0052] The tilt transmission rods 28 can be provided in two groups, that is, one group is provided on the inner side of each second connecting plate 16 , and can be provided as a group.

[0053] Each of the tilt transmission frames 21 is connected to an independent second power device 20, or a group of mechanisms can simultaneously control the tilt, for example Figure 1-12 Based on the combination Figure 13-15 , a horizontal track 30 is provided on the rear side of each set of back plates 11, and a through shaft extends from one side of the base frame 4 to the other side and passes through each set of tracks 30, moving back and forth along the track 30. A second power device (such as one or more sets of oil cylinders, not shown in the figure) is connected to the through shaft 32. The rear side 33 of the tilting force transmission frame corresponding to the core mold 3 that needs to be tilted is connected to the through shaft 32 through a detachable fixing part 31, so that the tilting force transmission frame 21 and the through shaft 32 form a whole, so that when the through shaft 32 moves on the track 30, it drives the tilting force transmission frame 21 to move, and then drives the core mold 3 to tilt. In this embodiment, the detachable fixing part 31 includes two sets of generally semicircular lock buckles, of course, it can also be other forms.

[0054] When it is necessary to clean the core mold 3 on a certain core mold support frame 10, that is, when it is necessary to tilt the core mold 3, the through shaft 32 is fixed to the tilting force transmission frame 21 corresponding to the core mold support frame 10 using a detachable fixing member 31, thereby driving the tilting force transmission frame 21 to move, causing the core mold 3 to tilt. If it is not necessary to tilt a certain core mold, it is not necessary to fix the through shaft 32 and the tilting force transmission frame 21 with the detachable fixing member 31. In this case, the tilting force transmission frame 21 is equivalent to being separated from the through shaft 32. The movement of the through shaft 32 will not affect the tilting force transmission frame, and the corresponding core mold will naturally not tilt.

[0055] A slope 23 is constructed on one side of the bottom end of the second connecting plate 16 close to the back plate 11, so that when the core mold 3 is tilted along the main axis 12, the slope 23 rotates backward to a vertical state and rests on the back plate 11. In this way, the core mold 3 can obtain dual support from the back plate 11 and the tilting force transmission frame 21, thereby improving stability during tilting.

[0056] A first stopper plate 24 is provided inside the tilting reserved groove 13, and a second stopper plate 25 is provided on the outer edge of the back plate 11 below the tilting reserved groove 13, allowing the second connecting plate 16 to move between the first stopper plate 24 and the second stopper plate 25. A third stopper plate 26 is also provided horizontally on the back plate 11, allowing the tilting force transmission frame 21 to rest on the third stopper plate 26. These three sets of stoppers can straighten the core mold 3 when it tilts, preventing it from tilting or warping.

[0057] At this point, multiple functions such as slide rails, limiters, and tilting are integrated on a back plate 11, maximizing the use of space on the back plate 11. In addition, all parts of the core mold support frame can be disassembled and replaced. If only local parts are damaged, they can be replaced separately without replacing the entire set of equipment.

[0058] Furthermore, a distance is reserved between the back plate 11 and the fixed component for the second sliding connection member to pass through, so that the second sliding connection member can move to above the crossbeam 5 .

[0059] The fully automatic mold support and core-extraction equipment can be used in multiple groups, and the bracket 275 at the bottom of each group of the fully automatic mold support and core-extraction equipment can be provided with a walking track for moving between workstations.

[0060] The working method of the above-mentioned fully automatic mold support and core mold extraction equipment includes the following steps:

[0061] S1: Left-right spacing adjustment: adjust the distance between each group of core mold support frames 10.

[0062] S2: Supporting the mold upward: controlling the core mold support frame 10 to rise so that the core mold 3 enters the mold frame of the prefabricated component;

[0063] S3: Pulling the core mold 3 downward: After the concrete in the precast component mold frame solidifies or semi-solidifies, the core mold support frame 10 is controlled to descend and the core mold 3 is pulled out;

[0064] S4: Tilt the core mold 3: control the core mold 3 to tilt forward and clean the core mold 3;

[0065] S5: Return the formwork: control the core form 3 to return and repeat the upward formwork action.

[0066] This document uses specific examples to illustrate the inventive concept in detail. The above embodiments are only intended to help understand the core concept of the present invention. It should be noted that any obvious modifications, equivalent substitutions, or other improvements made by a person skilled in the art without departing from the inventive concept should be included within the scope of protection of the present invention.
