Description

Technical Field

[0001] The invention relates to the technical field of prefabricated component production, in particular to a prefabricated component forming die. Background Art

[0002] During building construction, to protect the safety of the underground main structure and the surrounding environment of the foundation pit, it is necessary to implement control measures such as support, reinforcement, and waterproofing of the foundation pit. Combining several prefabricated components into a wall is a common method for supporting and reinforcing the foundation pit. To facilitate the splicing of prefabricated components, concave and convex connection structures are generally installed on both sides of the prefabricated components to facilitate the splicing of the prefabricated components.

[0003] Existing prefabricated component forming molds usually have a molding component of a concave-convex connection structure set in the mold frame. After molding, the prefabricated component and the molding component of the concave-convex connection structure need to be lifted out together, and then the molding component needs to be removed by workers. It needs to be reinstalled before the next pouring. For example, the Chinese patent with application number 2021212528324 discloses a mold including a mold frame and a molding module that can be detachably installed on the mold frame. A draft wedge that is wide at the top and narrow at the bottom can be wedged between at least one inner side wall of the mold frame and the molding module. When demolding, the draft wedge is first pulled out of the mold frame. At this time, in the accommodating groove of the mold frame, the overall width of the molding module is smaller than the width of the accommodating groove. Then the molding module is lifted out of the mold frame. At this time, the prefabricated retaining pile is still in the molding module and is lifted out of the mold frame together with the molding module. Then the prefabricated retaining pile is removed from the molding module, resulting in less damage to the product and improving demolding efficiency. The demolding operation of the above-mentioned mold is cumbersome and has low production efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a prefabricated component forming die to solve the problems of complicated operation and low efficiency in the existing prefabricated component production process.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A prefabricated component forming die comprises a male die assembly and a female die assembly which are laterally spaced apart, and a driving mechanism for driving the male die assembly to move laterally back and forth;

[0007] The female mold assembly comprises a first female molded part and a second female molded part that are vertically detachably connected, and the first female molded part and the second female molded part are combined to form a side groove;

[0008] The male mold assembly includes a rigid mold, and a flexible mold installed on the rigid mold and arranged toward the side groove of the female mold assembly;

[0009] The driving mechanism is connected to a side of the rigid mold facing away from the flexible mold.

[0010] Compared to the prior art, the present invention has the following advantages: the female mold assembly is used to form the convex connecting structure on one lateral side of the prefabricated component, and the male mold assembly is used to form the concave connecting structure on the other lateral side of the prefabricated component. After the prefabricated component is formed between the male and female mold assemblies, it needs to move vertically upward to be released from the mold. However, the concave and convex connecting structures on both sides of the prefabricated component are located within the male or female mold assembly and cannot be directly released. Therefore, in the female mold assembly, the first female mold part and the second female mold part are separated to allow the convex connecting structure of the prefabricated component located on one side of the female mold assembly to move vertically upward to be released from the female mold assembly. In the male mold assembly, the rigid mold is driven by a driving mechanism to move toward the side away from the prefabricated component, thereby separating the concave connecting structure of the prefabricated component from the male mold assembly. Through the above steps, after the prefabricated component is formed, the male and female mold assemblies can quickly eliminate the restrictions that prevent the concave and convex connecting structures of the prefabricated component from being released from the mold. This simplifies the operation, facilitates the demolding of the prefabricated component, and helps increase production efficiency.

DETAILED DESCRIPTION

[0039] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0040] In this article, terms such as "upper, lower, inside, outside" are established based on the positional relationships shown in the drawings. Depending on the different drawings, the corresponding positional relationships may also change accordingly. Therefore, they cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" are only used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0041] The length direction of the prefabricated component forming mold is the longitudinal direction, the width direction of the prefabricated component forming mold is the transverse direction, and the height direction of the prefabricated component forming mold is the vertical direction.

[0042] Example 1

[0043] like Figure 1-6 As shown in Figures 8 and 8, this embodiment provides a prefabricated component forming mold, including a male mold assembly 2 and a female mold assembly 3 that are laterally spaced apart, and a driving mechanism for driving the male mold assembly 2 to move back and forth laterally; wherein, the female mold assembly 3 includes a first female molding part 31 and a second female molding part 33 that are vertically detachably connected, and the first female molding part 31 and the second female molding part 33 are combined to form a side groove 35; the male mold assembly 2 includes a rigid mold 21, and a flexible mold 22 installed on the rigid mold 21 and arranged toward the side groove 35 of the female mold assembly 3; the driving mechanism is connected to the side of the rigid mold 21 facing away from the flexible mold 22.

[0044] Specifically, the female mold assembly 3 is used to form the raised connecting structure on one lateral side of the prefabricated component, while the male mold assembly 2 is used to form the recessed connecting structure on the other lateral side of the prefabricated component. After being formed between the male and female mold assemblies 2 and 3, the prefabricated component needs to be moved vertically upward to be released from the mold. However, the recessed and raised connecting structures on both sides of the prefabricated component are located within the male or female mold assembly 2 and 3 and cannot be directly released. Therefore, for the female mold assembly 3, the first female molded part 31 and the second female molded part 33 are separated to allow the raised connecting structure of the prefabricated component located on one side of the female mold assembly 3 to move vertically upward to be released from the female mold assembly 3. For the male mold assembly 2, the rigid mold 21 is driven by the drive mechanism to move toward the side away from the prefabricated component. The deformation of the flexible mold causes the male mold assembly 2 or the rigid mold 21 to separate horizontally from the recessed connecting structure of the prefabricated component. Through the above steps, after the prefabricated component is formed, the male mold assembly 2 and the female mold assembly 3 can quickly eliminate the restrictions on the concave and convex connection structure of the prefabricated component from being ejected from the mold. The operation is simple, it is convenient for the prefabricated component to be demoulded, and it is beneficial to increase production efficiency.

[0045] Further, such as Figure 2 、 3As shown in Figures 5 and 6, the driving mechanism includes a mounting seat 212, a rotary power source 23 arranged on the mounting seat 212, and a first rotating shaft 24 connected to the output end of the rotary power source 23. First threaded segments are arranged at intervals on the first rotating shaft 24. The first threaded segment is meshed with a first screw member 211 that can move axially along the first threaded segment. The first screw member 211 is hinged with a second linking member 29. The second linking member 29 is hinged to the rigid mold 21. The second linking member 29 moves under the drive of the first screw member 211 to drive the rigid mold 21 to move back and forth in the lateral direction. Specifically, the rotary power source 23 drives the first rotating shaft 24 to rotate. A first screw connector 211, threaded onto the first threaded segment of the first rotating shaft 24, is connected to the rigid mold 21 via a second link 29. Rotation of the first rotating shaft 24 drives the first screw connector 211 to reciprocate longitudinally, thereby driving the second link 29 to rotate longitudinally. During rotation, the transverse projection of the second link 29 decreases or increases, thereby driving the rigid mold 21 to move laterally. The rotary power source 23 is a combination of an electric motor and a motor.

[0046] Furthermore, the drive mechanism also includes a second rotating shaft parallel to the first rotating shaft 24, with first threaded segments spaced apart on the second rotating shaft. A first screw connector 211 is meshedly connected to the first threaded segment and axially movable along the first threaded segment. The first screw connector 211 is rotatably connected to a second linking member 29, which is rotatably connected to the rigid mold 21. Furthermore, the output end of the rotary power source 23 is connected to a first transmission wheel, the second rotating shaft is provided with a second transmission wheel, and a transmission chain 214 is provided between the first transmission wheel and the second transmission gear 213. The rotary power source 23 transmits power to the second rotating shaft via the first transmission wheel, the transmission chain, and the second transmission wheel. The first transmission wheel and the second transmission gear 213 have the same number of teeth, that is, under the action of the transmission chain 214, the first transmission wheel and the second transmission gear 213 have the same rotational speed. The principle by which the second rotating shaft drives the second linking member 29 to cause the rigid mold 21 to reciprocate laterally is the same as the principle by which the first rotating shaft 24 drives the second linking member 29 to cause the rigid mold 21 to reciprocate laterally. This description will not be repeated here; for details, please refer to the previous description of the principle by which the first rotating shaft 24 drives the second linking member 29 to cause the rigid mold 21 to reciprocate laterally. By providing both the first rotating shaft 24 and the second rotating shaft to simultaneously drive the movement of the rigid mold 21, the number of force points on the rigid mold 21 is increased, making the rigid mold 21 more stable during lateral movement.

[0047] Furthermore, the cross-sectional profile of the side protrusions and side grooves 35 is roughly T-shaped; and / or, the cross-sectional profile of the side protrusions and side grooves 35 is roughly L-shaped; and / or, the cross-sectional profile of the side protrusions and side grooves 35 is roughly semi-dovetail-shaped; and / or, the cross-sectional profile of the side protrusions and side grooves 35 is roughly arc-shaped. As long as the side protrusions and side grooves 35 can achieve the formed prefabricated components to be able to fit together along the transverse concave-convex snap-fit, there is no specific restriction on the specific cross-sectional shape of the side protrusions and side grooves 35.

[0048] like Figure 11 、 12 As shown, the first female molded part 31 is further provided with a second positioning hole 32, and the second female molded part 33 is provided with a threaded hole 34. A second positioning pin that matches the second positioning hole 32 is inserted into the first female molded part 31 and is threadedly connected to the threaded hole 34. The female mold assembly 3 is composed of the first female molded part 31, the second female molded part 33, and the second positioning pin connecting the first female molded part 31 and the second female molded part 33. During the assembly process, the first female molded part 31 and the second female molded part 33 are positioned by aligning the second positioning hole 32 with the threaded hole 34. The second positioning pin is passed through the second positioning hole 32 and screwed into the threaded hole 34 to form the female mold assembly 3. The first female molded part 31 at least encloses the vertical upper side surface of the side groove 35 to ensure that after the first female molded part 31 is removed, the prefabricated component can be vertically removed from the second female molded part 33.

[0049] like Figure 7 、 8 As shown, further, the rigid mold 21 has a protrusion facing the direction of the mother mold assembly 3, and the flexible mold 22 is installed on the protrusion to form a side protrusion. When the cross-sectional profile of the side protrusion is roughly T-shaped, L-shaped, semi-dovetail-shaped, etc., which will limit the side protrusion from escaping the concave splicing structure of the prefabricated component, the side protrusion is set to be formed by a roughly rectangular protrusion and a flexible mold 22 installed on the outside of the protrusion. When the rigid mold 21 moves back and forth in the lateral direction, the flexible mold 22 preferably remains in the prefabricated component, and the protrusion is separated from the concave splicing structure of the prefabricated component with the rigid mold 21, avoiding the side protrusion being restricted by the concave splicing structure of the prefabricated component and unable to escape. Preferably, the inner angle of the protrusion facing the side of the prefabricated component is less than 90°, which can enhance the bonding force between the flexible mold 22 and the protrusion, making it easier to install the flexible mold 22 on the protrusion.

[0050] like Figure 7 As shown, further, a reinforcement member 215 is provided on the side of the rigid mold 21 facing the adjacent male mold assembly 2. The rigid mold 21 is subjected to the pressure of the concrete during the forming process of the prefabricated component. The reinforcement member 215 improves the structural rigidity of the rigid mold 21 to prevent the rigid mold 21 from being deformed during the forming process of the prefabricated component.

[0051] Example 2

[0052] The same parts in this embodiment as those in the first embodiment are given the same reference numerals, and the same text descriptions are omitted.

[0053] Compared with the first embodiment, the driving mechanism provided in this embodiment has the following different structural design: the driving mechanism includes a power source and a first linkage, one end of the first linkage is connected to the output end of the power source, and the other end is connected to the rigid mold 21, the power source drives the rigid mold 21 to move back and forth in the lateral direction through the first linkage, the output end of the power source is connected to the first linkage to drive the first linkage to move or rotate, thereby driving the rigid mold 21 to move back and forth in the lateral direction, and there is no specific restriction on the structure of the power source and the first linkage, as long as the effect of driving the rigid mold 21 to move back and forth in the lateral direction can be achieved. Provided herein is a structural form of a power source and a first linkage, wherein the power source is a hydraulic cylinder, and the first linkage is a connecting rod, and the power source drives the output end to drive the first linkage to move back and forth in the lateral direction, thereby driving the rigid mold 21 to move back and forth in the lateral direction.

[0054] Example 3

[0055] The same parts in this embodiment as those in the first and second embodiments are given the same reference numerals, and the same textual descriptions are omitted.

[0056] like Figure 10 、 11As shown, compared with the first embodiment, the first rotating shaft 24 and the second rotating shaft provided in this embodiment have the following different structural designs: a second threaded segment adjacent to the first threaded segment is provided on the first rotating shaft 24, and the thread rotation direction of the second threaded segment is opposite to that of the first threaded segment. The second threaded segment is meshedly connected with a second screw member. The first screw member 211 and the second screw member are respectively rotatably connected to a second connecting member 29, and the two second connecting members 29 are rotatably connected to the same position or adjacent positions of the rigid mold 21. The rotary power source 23 drives the first rotating shaft 24 to rotate. Because the first screw member 211 and the second screw member are screwed to the first rotating shaft 24 and the thread rotation direction of the second threaded segment is opposite to that of the first threaded segment, when the first rotating shaft 24 rotates, the first screw member 211 and the second screw member are driven to move closer to each other or farther away from each other in the longitudinal direction, thereby driving the second connecting member 29 to rotate. During the rotation of the second connecting member 29, the horizontal projection length of the second connecting member 29 will shorten or increase. When the first When the screw connector 211 and the second screw connector move closer to each other along the longitudinal direction, the second connecting member 29 will drive the rigid mold 21 to move laterally in the direction away from the first rotating shaft 24. When the first screw connector 211 and the second screw connector move away from each other along the longitudinal direction, the second connecting member 29 will drive the rigid mold 21 to move laterally in the direction close to the first rotating shaft 24. The rigid mold 21 is driven to move laterally at the same time by the first screw connector 211 and the second screw connector, which is conducive to increasing the driving force and avoiding the situation where a single screw connector cannot pull the rigid mold 21 to move.

[0057] The second rotating shaft is provided with a second threaded segment adjacent to the first threaded segment, and the thread rotation direction of the second threaded segment is opposite to that of the first threaded segment. The second threaded segment is engaged with a second screwed member. The first screwed member 211 and the second screwed member are each rotatably connected to a second connecting member 29, and the two second connecting members 29 are rotatably connected to the same position or adjacent positions of the rigid mold 21. The principle by which the second rotating shaft drives the second connecting member 29 to cause the rigid mold 21 to reciprocate laterally is the same as the principle by which the first rotating shaft 24 drives the second connecting member 29 to cause the rigid mold 21 to reciprocate laterally. The details will not be repeated here. For details, please refer to the previous description of the principle by which the first rotating shaft 24 drives the second connecting member 29 to cause the rigid mold 21 to reciprocate laterally. By providing the first rotating shaft 24 and the second rotating shaft to simultaneously drive the movement of the rigid mold 21, the force points on the rigid mold 21 are increased, making the rigid mold 21 more stable during movement.

[0058] Example 4

[0059] In this embodiment, the same parts as those in the first, second and third embodiments are given the same figure marks, and the same text descriptions are omitted.

[0060] like Figure 1-6As shown, the prefabricated component mold disclosed in the present invention also includes a mold frame 1. Two or more sets of male mold assemblies 2 and female mold assemblies 3 are arranged transversely within the mold frame 1, with adjacent male mold assemblies 2 disposed in a direction opposite to each other. A drive mechanism is located between the two adjacent male mold assemblies 2. The mold frame 1, the male mold assemblies 2, and the female mold assemblies 3 collectively form a mold cavity 4. Top molds are provided on both longitudinal sides of the male and female mold assemblies 2 and 3. A drive mechanism is located between the two male mold assemblies 2, driving the rigid molds 21 of each male mold assembly 2 to reciprocate transversely to ensure that all prefabricated components within the mold cavity 4 can be smoothly demolded.

[0061] Furthermore, the driving mechanism also includes a base 25 and a first positioning pin 26, and positioning members 27 are provided at both ends of the rigid mold 21. The positioning members 27 and the base 25 are provided with first positioning holes adapted to the first positioning pin 26; corresponding to the two adjacent male mold assemblies 2 and the driving mechanism therein, the first rotating shaft 24 and the second rotating shaft are both provided with bearing seats 28, and the bearing seat 28 is connected to the rigid mold 21 of one male mold assembly 2, and the second linking member 29 is connected to the rigid mold 21 of the other male mold assembly 2, so that the two ends of the second linking member 29 are directly or indirectly connected to the rigid molds 21 of the two male mold assemblies 2 respectively. During demolding, the rigid mold 21 of one male mold assembly 2 is fixed to the base 25 by the first positioning pin 26, and the driving mechanism drives the second linking member 29 to rotate. Since the position of the rigid mold 21 of one male mold assembly 2 is fixed, the second linking member 29 will drive the rigid mold 21 of the other male mold assembly 2 to move back and forth laterally during the rotation process.

[0062] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
