Description

Technical Field

[0001] This utility model relates to the field of industrialized production equipment for building machinery, and in particular to a mechanical core structure for producing self-insulating integrated wall panels. Background Technology

[0002] With the increasing demands for efficiency and quality in the construction industry, mechanical core structures play a crucial role in wall panel manufacturing, mainly used in the production of integrated self-insulating concrete wall panels, lightweight wall panels, and the like.

[0003] Traditional production of self-insulating integrated wall panels typically involves on-site casting for both internal and external insulation, or precast concrete wall panels, with insulation materials, outer leaf panels, and face panels all formed in stages. Mechanical molds, on the other hand, use a pre-designed self-insulating cavity within the wall panel. Concrete pouring involves multiple wall panels integrated into a single, side-mounted mold, forming a hollow double-limb wall panel. The cavity is then filled with foamed insulation material to create the self-insulating wall panel. However, traditional insulation wall panels are formed by casting different sized wall panels in two stages, creating a sandwich-type insulation wall panel. This method cannot meet the demands of modern mechanized production. It requires redesigning and manufacturing molds of different specifications. Furthermore, due to strong adhesion or poor mold design, the demolding process is inefficient, leading to damage to the wall panel or the mold itself. Flat mold production also has drawbacks such as requiring a large factory area.

[0004] Therefore, it is particularly important to develop a mechanical mold core structure that can produce adjustable wall panels in length, width, and height using a side-mounted mold and achieve automatic demolding, thereby improving the adaptability of the mechanical mold core configuration, the quality of integrated manufacturing of self-insulating wall panels, and the efficiency of automated production.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] Because the mechanical mold cores currently used cannot adapt to new production needs when the design or specifications of the wall panel change, requiring the mold to be redesigned and remanufactured, and due to strong adhesion or unreasonable mold design, the demolding process of the wall panel is inefficient, leading to damage to the wall panel or the mold. Therefore, in order to adjust the size of the wall panel and achieve automatic demolding, thereby improving the adaptability of the mechanical mold core and the quality and efficiency of wall panel manufacturing, this application provides a mechanical mold core structure.

[0037] The mechanical mold core structure provided in this application is used for prefabricating integrated hollow components of self-insulating wall panels. The mechanical mold core structure includes:

The upper mold core housing 101 and the lower mold core housing 102 are both U-shaped and are symmetrically arranged on both sides of the hollow square tube shaft 2.

[0047] Optionally, the mold core housing 1 is located on both sides of the hollow square tube shaft 2, and the upper mold core housing 101 and the lower mold core housing 102 are the same in shape and size and are symmetrically arranged.

[0048] Optionally, the material and thickness of the mold core shell 1 can be set according to actual business needs, and are not limited here. For example, the mold core shell 1 can be made of 2.5mm thick Q345 cold-rolled steel plate by bending process.

[0049] Optionally, the two symmetrical parts of the mold core shell 1 are placed on both sides of the hollow square tube shaft 2, and the two sides of the mold core shell 1 are directly overlapped on the hollow square tube shaft 2 with an overlap length of 10mm.

[0051] The upper mold core shell 101 and the lower mold core shell 102 are both U-shaped. The U-shaped structure has high rigidity and can effectively resist external forces and maintain its shape, thereby improving the stability of the entire mold core system. At the same time, the symmetrical arrangement can ensure that the stress is evenly distributed during the processing, reducing deformation or damage caused by stress concentration.

[0052] Optionally, the hollow square tube shaft 2 is a telescopic hollow square steel tube. The material and size of the hollow square tube shaft 2 can be set according to actual business needs and are not limited here. For example, Q345 square steel tube with specifications of 3x60x80mm is used as the hollow square tube shaft 2. The total length of the hollow square tube shaft 2 exceeds the floor height of the wall panel and the length of the mold core.

[0053] Optionally, a standard length mold handle fixture is reserved on the hollow square tube shaft 2, and a length limit design is provided.

[0054] Optionally, a clamp can be provided at the root of the hollow square tube shaft 2 for limiting its position.

[0055] Optionally, the bracing connecting pin 4 is configured as a double-row structure, with the bracing connecting pin 4 arranged symmetrically and both ends of the bracing connecting pin 4 fixed on the hollow square tube shaft 2.

[0056] Optionally, holes that mate with the bracing connecting pins 4 are evenly opened on the same plane of the hollow square tube shaft 2. The head holes of these holes are fixed by welding and have ground pins.

[0057] Optionally, the hollow square tube shaft 2 is provided with an elongated groove, so that the support connecting piece can move in the groove.

[0058] Optionally, the support connecting piece pin 4 is provided with a pin head hole plug welding structure, the head of the support connecting piece pin 4 has a hole, and this hole is sealed by a plug welding process.

[0059] Optionally, a support connecting piece 3 is provided on the support connecting piece pin 4. The support connecting piece 3 is provided with a slot for connecting other parts or for inserting pins, etc., and also has a corresponding bolt hole for passing through bolts, as well as a slot corresponding to the assist rod 5.

[0060] Optionally, a clamp is installed at the root of the hollow square tube shaft 2. The clamp has a limiting function, enabling the equipment to firmly hold the mold handle at the root of the hollow square tube shaft 2. When performing insertion and removal operations to expand or contract the internal mold core structure, the clamp can effectively hold the mold handle and the shaft head of the hollow square tube shaft 2. This configuration allows the mold core to be inserted and expanded, thus enabling the mold core to function. When it needs to be removed or pulled out, it can automatically retract for easy operation.

[0061] The double-row bracing connecting pins 4 provide stronger fixing and higher connection strength, making the hollow square tube shaft stable during expansion and contraction, less prone to displacement or loosening, and distributing the load more evenly on the hollow square tube shaft 2 and the bracing connecting plates 3, reducing the pressure on individual fixing points, thereby improving the overall load-bearing capacity. The design of the double-row bracing connecting pins 4 and the bracing connecting plates 3 has significant advantages in improving structural stability, load-bearing capacity, safety and reliability.

[0062] Optionally, the assist rod 5 is located at the top and bottom of the mold core housing 1, and passes through the slot on the symmetrical surface of the hollow square tube shaft 2 in a vertical direction to form a cross-shaped fixed arrangement.

[0063] In an optional embodiment, the reinforcing plate 8 is U-shaped and is symmetrically arranged on the inner sides of both ends of the upper mold core shell 101 and the lower mold core shell 102. The reinforcing plate 8 has corresponding slots and is fixedly connected to the mold core shell 1 at the connection point 15 between the reinforcing plate and the mold core shell. The two ends of the assist rod 5 are respectively arranged through the slots on the reinforcing plate 8.

[0064] Optionally, the two ends of the reinforcing plate 8 are bent, and the bent ends of the reinforcing plate 8 are welded to the U-shaped mold core shell 1 at the connection point 15 between the reinforcing plate and the mold core shell.

[0065] In an optional embodiment, the mechanical mold core structure further includes a support and tension connecting piece pin ear 81, which is provided with a pin hole and contains a pin shaft 14 on the support and tension connecting piece pin ear. The support and tension connecting piece pin ear 81 is vertically and evenly arranged on the reinforcing plate 8 and is fixedly connected to the reinforcing plate 8.

[0066] In an optional embodiment, the other end of the support connecting piece 3 is connected to the reinforcing plate 8 which is evenly distributed on the top and bottom. The support connecting piece 3 is located between two adjacent support connecting piece pin ears 81 and is connected to the pin shaft 14 on the support connecting piece ear. It is used to be movably connected in the hole of the support connecting piece 3 and movably connected to the support connecting piece 3 in the pin hole.

[0067] Optionally, the number of tension connecting piece pin ears 81 is four. Two tension connecting piece pin ears 81 are provided on both sides of the bottom of each tension connecting piece 3, and the tension connecting piece pin ears 81 are fixedly connected to the reinforcing plate 8. The tension connecting piece pin ears 81 can ensure the fixation of the tension connecting piece 3 and the connection between the tension connecting piece 3 and the reinforcing plate 8, making the connection more secure, improving the stability of the overall structure, thereby reducing wear and extending the service life of the components. At the same time, the fixing components can help maintain the correct position of the tension connecting piece and ensure the accuracy of the overall structure.

[0068] Optionally, the two ends of the tension connecting piece 3 are provided with pin holes, and the pin holes of the tension connecting piece 3 are vertically and evenly arranged on the inner pin of the hollow square tube shaft 2, and are movably connected with the corresponding pin holes of the tension connecting piece 3 on the inner pin of the hollow square tube shaft 2. The pin ears 81 of the tension connecting piece are fixed to the reinforcing plate 8 by welding.

[0069] By setting the reinforcing plate 8, the overall strength and rigidity of the structure can be improved, making the part where the bracing connecting piece pin ear 81 is located more able to withstand external forces and vibrations, and more stable when fixed on the reinforcing plate 8. It is not easy to loosen or deform due to impact or vibration, maintain the accuracy of the connection, and effectively disperse the stress acting on the bracing connecting piece, reduce stress concentration, thereby reducing the risk of fracture and improving the reliability of the entire structure.

[0070] In an optional embodiment, the center of the inward limiting member 7 and the outward limiting member 9 are respectively provided with bolt holes. The inward limiting member 7 and the outward limiting member 9 are connected to the spring plate 6 by connecting bolts 10 passing through the corresponding bolt holes on the hollow square tube shaft 2.

[0071] Optionally, a spring sheet 6 is provided on the outer side of the mold core shell 1. The material and size of the spring sheet 6 can be set according to actual business needs and are not limited here. For example, the spring sheet 6 can be a steel plate with a thickness of 1mm and a width of 6mm. The steel plate is formed by pressing, leaving a 20mm wide flat surface in the middle without bending, and the remaining part is divided into two equal halves. Each half is bent outward to form an arch with a height of 2.5mm to form the spring sheet 6.

[0072] Optionally, the inward limiting member 7 is a limiting pad strip on the spring plate 6, which is set at the center of the spring plate 6 and integrally formed with the spring plate 6. The inward limiting member 7 is provided with a central slot corresponding to the inward limiting member 7 and the outward limiting member 9. The three are connected into one body by connecting bolts 10 and can move inward and outward along the overall wall edge between the hollow square tube shaft 2.

[0073] Optionally, the material and thickness of the inward limiting member 7 can be set according to actual business needs, and are not limited here. For example, the thickness of the limiting pad strip is 3mm, and the pad strip is provided with holes, which correspond to the holes on the spring sheet 6.

[0074] Optionally, a row of holes with standard spacing is provided at the center of the inward limiting member 7 for installing the connecting bolt 10. The center of the inward limiting member 7, the outward limiting member 9, and the hollow square tube shaft 2 are connected by a connecting bolt 10. The size of the connecting bolt 10 can be set according to actual business needs and is not limited here. For example, the connecting bolt 10 can be a flat-head screw with a diameter of 3mm. The head of the flat-head screw is ground flat with the surface of the steel plate to ensure flatness. By setting the spring plate 6, it can play a buffering role when the hollow square tube shaft 2 is extended and retracted, and at the same time realize the adjustment of the wall panel size and automatic demolding.

[0075] Optionally, the preset distance between the inward limiting member 7 and the spring plate 6 can be set according to actual business needs and is not limited here. For example, a gap of 1.5mm is maintained between the inward limiting member 7 and the spring plate 6. Maintaining a certain amount of compression can provide a certain degree of flexibility in the assembly of the hollow square tube shaft, resulting in higher alignment accuracy and better adaptability and protection for the hollow square tube shaft 2. This design ensures that the spring plate 6 will not be excessively ejected due to external force, while also being able to compress inward by 1.5mm under internal pressure, maintaining a certain degree of elastic buffer. When the hollow square tube shaft 2 is subjected to core pulling operation, if the spring plate 6 is subjected to pressure exceeding its design, it can move freely within this 1.5mm gap, thereby avoiding damage due to overpressure and helping to improve the performance and reliability of the overall mechanical system.

[0076] In an optional embodiment, the upper and lower ends of the assist rod 5 are respectively provided with two assist rod pin ears 51 with pin holes. The assist rod pin ears 51 are L-shaped. The pin holes of two adjacent assist rod pin ears 51 are connected by an assist rod force-sliding movable pin 16. The assist rod pin ears 51 and the reinforcing plate 8 are fixedly connected at the connection point 17 between the assist rod pin ears and the reinforcing plate.

[0077] Optionally, two symmetrical L-shaped assist rod pin ears 51 are provided at both ends of the assist rod 5. The assist rod pin ears 51 are provided with upper and lower pin holes, and pin anchors are provided in the pin holes. The shape of the assist rod pin ears 51 is L-shaped. The pin shafts in the pin holes of two adjacent assist rod pin ears 51 are movably connected by the assist rod force sliding pin shaft 16. The assist rod pin ears 51 and the reinforcing plate 8 are fixedly connected at the connection point 17 between the assist rod pin ears and the reinforcing plate.

[0078] Optionally, the assist rod 5 is U-shaped and located at the center of the hollow square tube shaft 2 in the horizontal direction. The assist rod 5 passes through a pre-reserved slot on the hollow square tube shaft 2. According to design standards, the outward extension length of the assist rod 5 is symmetrically reserved and pre-welded into place. An assist rod sliding movable pin 16 is provided on the assist rod pin lug 51. The assist rod pin lug 51 and the reinforcing plate 8 are fixed together by welding at the connection point 17 between the assist rod pin lug and the reinforcing plate. There can be several connection points 17 between the assist rod pin lug and the reinforcing plate. This design allows the assist rod 5 to help stabilize the entire mold core when inserting or removing it. The assist rod sliding movable pin 16 is provided on 51 for assisting in the expansion and contraction of the model, passing through the assist rod 5 and the assist rod pin lug 51.

[0079] In an optional embodiment, two hollow rubber ring long seal strips 11 are symmetrically arranged on the upper and lower outer sides of the mold core shell 1, and each hollow rubber ring long seal strip 11 is provided with a fixing long pressure strip 12 for fixing the hollow rubber ring long seal strip 11 to the mold core shell 1 by bolts.

[0080] Optionally, the number of hollow rubber ring long seals 11 can be set according to actual business needs, and is not limited here. For example, two hollow rubber ring long seals 11 are provided on the outside of the upper mold core shell 101 and two on the outside of the lower mold core shell 102, and are arranged symmetrically. The hollow rubber ring long seals 11 tubes are elastic.

[0081] In an optional embodiment, bolt holes are evenly provided on the fixed longitudinal pressure strip 12, and the bolt holes on the fixed longitudinal pressure strip 12 are fixedly connected to the mold core shell 1 by bolts.

[0082] Optionally, a fixing strip 12 is provided inside each hollow rubber ring long seal 11. The material of the fixing strip 12 can be set according to actual business needs and is not limited here. For example, the fixing strip 12 can be a thin steel strip with slots. Self-tapping bolts are passed through the holes of the rubber strip tube and the strip to fix the strip to the outer wall of the mold core shell 1. This design allows adjacent hollow rubber ring long seals 11 to be joined together, thereby clamping the diagonal web members and transverse members on the truss reinforcement. Adjacent hollow rubber ring long seals 11 can prevent concrete from seeping into the mold core. During the concrete pouring process, the polyurethane insulation core material in the wall panel will foam and fill the entire insulation core material, making it interconnected and realizing the self-insulating function of the wall panel, thereby achieving the effect of ultra-low energy consumption. It also allows the polyurethane insulation material to be tightly bonded to the concrete wall, ensuring that the wall panel has good airtightness and preventing concrete from seeping into the mechanical mold core structure.

[0083] In an optional embodiment, a mold core limiting member 13 is provided between two adjacent hollow rubber ring long seals 11 for limiting the mechanical mold core structure and the mold structure, and the mold core limiting member 13 is obliquely symmetrically arranged.

[0084] Optionally, two core limiting components 13 are provided, both positioned between the two hollow rubber rings and the long sealing strips 11. These components restrict the insertion of the core, ensuring that the core housing 1 maintains the same insertion distance and expands to its maximum size during insertion. This design ultimately creates a uniform cavity in the center of the wall panel, which can be connected to the foaming material to form a unified self-insulating wall panel structure.

[0085] Optionally, after the mechanical mold core is inserted, the hollow square tube shaft 2 expands and locks to both sides by the up and down movement of the support connecting piece 3 to achieve the required inner mold core size, thus obtaining the standard insulation core thickness and width. After the poured concrete reaches the set strength, the hollow square tube shaft 2 is pushed out, causing the mold core shell 1 to shrink and separate from the concrete contact surface, thereby achieving automatic demolding.

[0086] The mechanical mold core structure provided in this application will be described in its entirety below:

[0087] The mechanical mold core structure consists of a retractable hollow square tube shaft 2 in the middle of the main body, and two symmetrically bent U-shaped upper mold core shells 101 and lower mold core shells 102 on both sides. The symmetrical U-shaped mold core shells 1 are provided with bent L-shaped reinforcing plates 8 that extend the length of the mold core shells 1, and are evenly perforated and spot-welded to the two side walls of the U-shaped shells.

[0088] Two rows of upper and lower support connecting piece pin ears 81 are welded on both sides of the reinforcing plate 8. The support connecting piece pin ears 81 contain pin holes and are connected to the pin holes at one end of the support connecting piece 3. The pin holes at the other end of the support connecting piece 3 are connected to two rows of upper and lower resistance pins provided on both sides of the hollow square tube shaft 2. The two ends of the resistance pins are drilled and welded to the tube wall of the hollow square tube shaft 2. The slots of the mold core shell 1 are respectively placed on the plane of the hollow square tube shaft 2. The symmetrical center of the slots of the mold core shell 1 is set with a telescopic distance greater than or equal to 15mm until the inward limiting member 7 of the center limit is reached.

[0089] A long spring plate 6 is provided on the outside of the mold core shell 1 and its inner limiting member 7. Bolt holes are evenly distributed on the spring plate 6. The bolt holes corresponding to the bolts are connected to the outer limiting member 9 provided inside the hollow square tube shaft 2 for limiting connection. This allows the two sides of the outer spring plate 6 to press against the U-shaped opening edge of the mold core shell 1 on both sides and slide back and forth on both sides of the hollow square tube shaft 2 within the maximum extension distance. This achieves the required mold hole standard for the insulation core thickness and width after the hollow square tube shaft 2 is inserted and expanded and locked to both sides by the support connecting piece 3. When the poured concrete reaches the set strength, the hollow square tube shaft 2 is pushed out, causing the mold core shell 1 to shrink and separate from the concrete contact surface, thus realizing the automatic demolding of the inner mold core.

[0090] The mechanical mold core structure provided in this application includes a mold core shell 1, which is U-shaped and symmetrically arranged; a hollow square tube shaft 2, which has corresponding through slots and is located inside the center of the mold core shell 1; an assist rod 5, which passes vertically through slots on both walls of the hollow square tube shaft 2; a tension connecting pin 4, whose two ends are fixedly connected to the hollow square tube shaft 2; and a tension connecting piece 3, whose two ends are provided with pin holes. One end of the connecting piece 3 is connected to the assist rod 5 via the connecting pin 4, and the other end is connected to the pin 14 on the connecting lug of the connecting piece; the spring piece 6 symmetrically covers the outer side of the mold core shell 1; the inward limiting member 7 is disposed on the spring piece 6 and is connected to the spring piece 6 as a whole; the outward limiting member 9 is located on the inner side of the hollow square tube shaft 2, and the center of the outward limiting member 9 and the center of the inward limiting member 7 are provided with corresponding bolt holes and are connected as a whole by the connecting bolt 10. By inserting the hollow square tube shaft 2 into the rear support connecting piece to expand it to both sides, the required mold core size standard is achieved. After the poured concrete reaches the set strength, the hollow square tube shaft 2 is pushed out, causing the mold core shell 1 to shrink and separate from the concrete contact surface. This allows for adjustment of the length, width, and height of the wall panel and automatic demolding, thereby improving the quality of integrated manufacturing of self-insulating wall panels, increasing automated production efficiency, and enhancing the adaptability of configuring mechanical mold cores.

[0091] The above description is only an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
