Description

Technical Field

[0001] The present invention relates to the technical field of industrial production equipment for construction machinery, and particularly to a mechanical die core structure for producing self-insulating integrated wall panels. Background Art

[0002] With the increasing requirements for efficiency and quality in the construction industry, the mechanical die core structure plays a crucial role in the manufacture of wall panels, mainly used for the production of concrete self-insulating integrated wall panels, lightweight wall panels, etc.

[0003] Traditional production of self-insulating integrated wall panels usually adopts on-site cast-in-place for internal and external insulation or precast concrete wall panels, and the insulation materials, outer leaf panels, and panels are formed in separate steps. The mechanical die core is designed with a self-insulating cavity held inside the predetermined wall panel. The concrete is poured by standing upright in the mold to integrally cast multiple wall panels at one time. The left and right walls of the integral formed cavity are integrated and connected into a whole hollow double-limb wall panel. Then, the cavity is filled with foamed insulation material to form a self-insulating wall panel. However, traditional insulating wall panels are formed by pouring and reverse casting different specifications of wall panels in two flat steps to form a thermal insulation sandwich wall panel, which cannot meet the new mechanized production requirements, requires re-designing and manufacturing different specifications of molds, and due to strong adhesion or unreasonable mold design, the efficiency of the wall panel demolding process is low, resulting in damage to the wall panel or the mold, and the large floor area occupied by flat mold production, etc.

[0004] Therefore, it is particularly important to develop a mechanical die core structure that can produce adjustable wall panel lengths, widths, and heights by side-standing molds and achieve automatic demolding, thereby improving the adaptability of the mechanical die core for automatic demolding in concrete walls, the quality of integrated manufacturing of self-insulating wall panels, and the efficiency of industrialized production.

[0033] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0034] As used herein, the term "one embodiment" or "embodiment" refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present application. In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present application. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0036] Since the currently used mechanical die core cannot adapt to new production requirements when the design or specifications of the wall panel change, it is necessary to redesign and manufacture the die. And due to strong adhesiveness or unreasonable die design, the efficiency of the wall panel demolding process is low, resulting in problems such as wall panel damage or die damage. Therefore, in order to adjust the size of the wall panel and achieve automatic demolding, thereby improving the adaptability of the mechanical die core, as well as the quality and efficiency of wall panel manufacturing, the present application provides a mechanical die core structure.

[0037] The mechanical die core structure provided by the present application is used for precast self-insulating wall panel integrated hollow components, and the mechanical die core structure includes:

[0038] A die core housing 1, the shape of the die core housing 1 is U-shaped and symmetrically arranged;

[0039] A hollow square tube shaft 2, corresponding through slots are provided on the hollow square tube shaft 2, and the hollow square tube shaft 2 is located inside the center of the die core housing 1;

[0045] An outward limiting member 9 is provided, and the outward limiting member 9 is located inside the hollow square tube shaft 2. Corresponding bolt holes are provided at the centers of the outward limiting member 9 and the inward limiting member 7, and they are connected integrally by a connecting bolt 10.

[0046] In an alternative embodiment, the die core housing 1 includes a symmetrically arranged upper die core housing 101 and a lower die core housing 102. The upper die core housing 101 and the lower die core housing 102 are both U-shaped, and the two are symmetrically arranged on both side edges of the hollow square tube shaft 2.

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

[0048] Optionally, the material and thickness of the die core housing 1 can be set according to actual business requirements and are not limited herein. Exemplarily, the die core housing 1 can be made of 2.5 mm thick Q345 cold-rolled steel plate through a bending process.

[0049] Optionally, the two symmetric parts of the die core housing 1 are respectively placed on both sides of the hollow square tube shaft 2. The two sides of the die core housing 1 are directly lapped on the hollow square tube shaft 2, and the lapping length is 10 mm.

[0050] Optionally, the two sides of the die core housing 1 can be contracted inward, with each side contracting 15 mm until reaching the inward limiting member 7 for central limiting.

[0051] The upper die core housing 101 and the lower die core housing 102 are both U-shaped. The U-shaped structure has high rigidity, can effectively resist external forces, maintain the shape unchanged, thereby improving the stability of the entire die core system. At the same time, the symmetric arrangement can ensure uniform stress distribution 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 pipe. The material and size of the hollow square tube shaft 2 can be set according to actual business requirements and are not limited herein. Exemplarily, a Q345 square steel pipe with a specification of 3x60x80 mm is used to make the hollow square tube shaft 2, and the total length of the hollow square tube shaft 2 exceeds the floor height of the wall panel and the length of the die core.

[0053] Optionally, a die handle fixture with a standard length is reserved on the hollow square tube shaft 2, and there is a design for length limitation.

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

[0055] Optionally, the tension link pin shaft 4 is arranged in a double-row structure, the tension link pin shafts 4 are symmetrically arranged, and both ends of the tension link pin shaft 4 are fixed on the hollow square tube shaft 2.

[0056] Optionally, on the same plane of the hollow square tube shaft 2, holes matching the tension link pin shaft 4 are evenly opened. The head holes of these holes are fixed by welding and have ground pin holes.

[0057] Optionally, the hollow square tube shaft 2 is provided with elongated slots so that the tension link can move in the slots.

[0058] Optionally, the tension link pin shaft 4 is provided with a structure of plug welding for the pin head hole. There is a hole in the head of the tension link pin shaft 4, and this hole is closed by plug welding process.

[0059] Optionally, a tension link 3 is arranged on the tension link pin shaft 4. The tension link 3 is provided with notches for connecting other components or for inserting pins, etc., and corresponding bolt holes for passing bolts, as well as notches corresponding to the booster rod 5.

[0060] Optionally, a clamping fixture is installed at the root of the hollow square tube shaft 2. The clamping fixture has a limiting function and can firmly hold the die handle at the root of the hollow square tube shaft 2 of the die core. When performing plugging and unplugging operations to expand and contract the internal die core structure, the clamping fixture can effectively hold the die handle and the shaft head of the hollow square tube shaft 2. Through this setting, the die core can be inserted and expanded, so that the die core can play a role. When it is necessary to remove or pull out, it can automatically contract for easy operation.

[0061] The double-row tension link pin shafts 4 can provide stronger fixing effect and higher connection strength, so that the hollow square tube shaft remains stable during the telescopic process, is not prone to deviation or loosening, and distributes the load more evenly on the hollow square tube shaft 2 and the tension link 3, reducing the pressure on a single fixing point, thereby improving the overall load-bearing capacity. The design of the double-row tension link pin shafts 4 fixedly connected to the tension link 3 has obvious advantages in improving structural stability, load-bearing capacity, safety and reliability.

[0062] Optionally, the booster rod 5 is arranged at the top and bottom of the die core housing 1 and passes through the hollow square tube shaft 2 vertically through the slot holes on the symmetrical plane of the hollow square tube shaft 2 to form a cross-shaped fixed setting.

[0063] In an alternative embodiment, the reinforcing plate 8 is U-shaped and symmetrically arranged on the inner sides of both ends of the upper die core housing 101 and the lower die core housing 102. The reinforcing plate 8 has corresponding slots and is fixedly connected to the die core housing 1 at the connection point 15 between the reinforcing plate and the die core housing. Both ends of the boosting 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 die core housing 1 at the connection point 15 between the reinforcing plate and the die core housing.

[0065] In an alternative embodiment, the mechanical die core structure further includes a tension and compression connection piece pin ear 81. The tension and compression connection piece pin ear 81 is provided with a pin hole, and a tension and compression connection piece ear pin 14 is contained in the pin hole. The tension and compression connection piece pin ears 81 are vertically and evenly arranged on the reinforcing plate 8 and fixedly connected to the reinforcing plate 8.

[0066] In an alternative embodiment, the other end of the tension and compression connection piece 3 is connected to the reinforcing plate 8 and is evenly distributed up and down. The tension and compression connection piece 3 is located between two adjacent tension and compression connection piece pin ears 81 and is correspondingly connected to the tension and compression connection piece ear pin 14 for movably connecting in the hole of the tension and compression connection piece 3 and movably connecting with the tension and compression connection piece 3 in the pin hole.

[0067] Optionally, the number of the tension and compression connection piece pin ears 81 is 4. Two tension and compression connection piece pin ears 81 are arranged on both sides of the bottom of each tension and compression connection piece 3, and the tension and compression connection piece pin ears 81 are fixedly connected to the reinforcing plate 8. The tension and compression connection piece pin ears 81 can ensure the fixation of the tension and compression connection piece 3 and the connection between the tension and compression connection piece 3 and the reinforcing plate 8 is more firm, improving the stability of the overall structure, thereby reducing wear and extending the service life of the components. At the same time, the fixing component can help maintain the correct position of the tension and compression connection piece and ensure the accuracy of the overall structure.

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

[0069] By providing the reinforcing plate 8, the overall strength and stiffness of the structure can be improved, so that the part where the tension and compression connection piece pin ears 81 are located can better withstand external forces and vibrations, is more stable when fixed on the reinforcing plate 8, is not easily loosened or deformed due to impact or vibration, maintains the accuracy of the connection, and effectively disperses the stress acting on the tension and compression connection piece, reduces stress concentration, thereby reducing the risk of fracture and improving the reliability of the entire structure.

[0070] In an alternative embodiment, bolt holes are respectively provided at the centers of the inward limiting member 7 and the outward limiting member 9.

[0071] Optionally, a spring piece 6 is provided on the outer side of the die core housing 1. The material and size of the spring piece 6 can be set according to actual business requirements and are not limited herein. Exemplarily, the spring piece 6 can be a steel plate with a thickness of 1 mm and a width of 6 mm. The steel plate is subjected to a profiling process, with a 20-mm-wide flat surface reserved in the middle part without bending, and the remaining part is evenly divided into two halves, and each half is bent outward to form an arch with a height of 2.5 mm, thus forming the spring piece 6.

[0072] Optionally, the inward limiting member 7 is a limiting backing strip on the spring piece 6, provided at the center of the spring piece 6 and integrally formed with the spring piece 6. The inward limiting member 7 is provided with central slot holes corresponding to the inward limiting member 7 and the outward limiting member 9. The three are integrally connected by a connecting bolt 10 and can move integrally along the inner and outer wall edges between the walls of 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 requirements and are not limited herein. Exemplarily, the thickness of the limiting backing strip is 3 mm, and holes are provided on the backing strip. The holes on the backing strip correspond to the holes on the spring piece 6.

[0074] Optionally, a row of holes arranged at a 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 requirements and is not limited herein. Exemplarily, the connecting bolt 10 can be a flat-head screw with a diameter of 3 mm. The head of the flat-head screw is ground flat with the surface of the steel plate to ensure flatness. By providing the spring piece 6, it can play a buffering role when the hollow square tube shaft 2 expands and contracts, and at the same time, it can adjust the size of the wall panel and achieve automatic demolding.

[0075] Optionally, the preset distance reserved between the inward limiting member 7 and the spring piece 6 can be set according to actual business requirements and is not limited herein. Exemplarily, a gap of 1.5 mm is reserved between the inward limiting member 7 and the spring piece 6. Retaining a certain amount of compression provides a certain degree of flexibility for the assembly of the hollow square tube shaft, with higher alignment accuracy, better adaptability and protection for the hollow square tube shaft 2. This design ensures that the spring piece 6 is not overly ejected due to external forces and can be compressed inward by 1.5 mm under internal pressure, maintaining a certain elastic buffer. When a core-pulling operation is performed inside the hollow square tube shaft 2, if the spring piece 6 is subjected to pressure exceeding its design limit, it can move freely within this 1.5-mm gap, thus avoiding damage due to overpressure and contributing to improving the performance and reliability of the overall mechanical system.

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

[0077] Optionally, two symmetric L-shaped assist lever pin ears 51 are provided at both ends of the assist lever 5. Upper and lower pin holes are provided on the assist lever pin ears 51, and there is a pin anchor connection inside the pin holes. The assist lever pin ears 51 are L-shaped. The pin shafts inside the pin holes of two adjacent assist lever pin ears 51 are movably connected by an assist lever force-bearing sliding pin shaft 16 to work. The assist lever pin ears 51 are fixedly connected to the reinforcing plate 8 at the connection point 17 between the assist lever pin ear and the reinforcing plate.

[0078] Optionally, the assist lever 5 is U-shaped and is located at the center of the hollow square tube shaft 2 in the horizontal direction. The assist lever 5 passes through a notch reserved on the hollow square tube shaft 2. According to the design standard, the overhanging length of the assist lever 5 is symmetrically reserved and pre-welded in place. An assist lever force-bearing sliding movable pin 16 is provided on the assist lever pin ear 51. The assist lever pin ear 51 and the reinforcing plate 8 are fixedly welded together at the connection point 17 between the assist lever pin ear and the reinforcing plate. There can be several connection points 17 between the assist lever pin ear and the reinforcing plate. Through this design, when inserting or removing the core, the assist lever 5 can help maintain the stability of the entire core. The assist lever force-bearing sliding movable pin 16 is provided on 51 to assist in the expansion and contraction of the model and penetrates through the assist lever 5 and the assist lever pin ear 51.

[0079] In an alternative embodiment, two hollow rubber ring full-length seals 11 are symmetrically arranged on the upper and lower outer sides of the core housing 1 respectively. A fixed full-length pressing strip 12 is arranged in each of the hollow rubber ring full-length seals 11 for fixedly connecting the hollow rubber ring full-length seals 11 and the core housing 1 together by bolts.

[0080] Optionally, the number of the hollow rubber ring full-length seals 11 can be set according to actual business requirements and is not limited herein. Exemplarily, there are two hollow rubber ring full-length seals 11 symmetrically arranged on the outer side of the upper core housing 101 and the outer side of the lower core housing 102 respectively, and the hollow rubber ring full-length seals 11 are elastic.

[0081] In an alternative embodiment, bolt holes are uniformly arranged on the fixed full-length pressing strip 12, and the bolt holes on the fixed full-length pressing strip 12 are fixedly connected to the core housing 1 by bolts.

[0082] Optionally, a fixed full-length pressing strip 12 is arranged inside each of the hollow rubber ring full-length seals 11. The material of the fixed full-length pressing strip 12 can be set according to actual business requirements and is not limited herein. Exemplarily, the fixed full-length pressing strip 12 can be a thin steel pressing strip. Groove holes are arranged on the thin steel pressing strip. The pressing strip is fixed on the outer side wall of the core housing 1 by self-tapping bolts passing through the holes of the rubber strip tube and the pressing strip. Through this design, adjacent hollow rubber ring full-length seals 11 can be butted, so as to clamp the diagonal web members and transverse ribs on the truss bars. Adjacent hollow rubber ring full-length seals 11 can prevent concrete from penetrating into the core. During the concrete pouring process, the polyurethane in the thermal insulation core material in the wall panel will foam and fill the entire thermal insulation core material, making it penetrate, realizing the self-thermal insulation function of the wall panel, thus achieving the effect of ultra-low energy consumption, and enabling the polyurethane thermal insulation material to be closely bonded to the concrete wall, ensuring that the wall panel has good airtightness and preventing concrete from penetrating into the mechanical core structure.

[0083] In an alternative embodiment, a core position-limiting member 13 is arranged between two adjacent hollow rubber ring full-length seals 11 for limiting the mechanical core structure and the mold structure, and the core position-limiting members 13 are arranged in an inclined and symmetrical manner.

[0084] Optionally, the number of the core position-limiting members 13 is 2, and they are both arranged between two hollow rubber ring full-length seals 11, which are used to play a limiting role when inserting the core, ensuring that when the core housing 1 is inserted, the same insertion distance can be maintained and expanded to the maximum size. Through this design, a unified cavity is finally reserved in the center of the wall panel, and this cavity can be connected to the foaming material to form an integral self-thermal insulation wall panel structure.

[0085] Optionally, after the mechanical die core is inserted, by moving the upper and lower tension and support connecting pieces 3, the hollow square tube shaft 2 expands and locks to both sides to reach the required inner die core size, obtaining the standard thickness and width of the thermal insulation core. After the poured concrete reaches the set strength, the hollow square tube shaft 2 is retracted, causing the die core shell 1 to shrink and separate from the concrete contact surface, thereby realizing automatic demolding.

By inserting the hollow square tube shaft 2, the stay connection piece is expanded to both sides, so as to reach the required die core size standard. After the poured concrete reaches the set strength, the hollow square tube shaft 2 is withdrawn, so that the die core outer shell 1 shrinks and is separated from the concrete contact surface, realizing the adjustment of the length, width and height of the wall panel, and realizing automatic demoulding, thereby improving the quality of the integrated manufacturing of the self-insulating wall panel, improving the automation production efficiency and the adaptability of the configured mechanical die core.
