Description

Technical Field

[0001] This utility model belongs to the field of molding machine technology, and in particular relates to a compression molding machine for a cement-based building non-removable composite template. Background Technology

[0002] With the rapid development of the construction industry, the demand for formwork is increasing, especially for high-strength, high-precision, easy-to-disassemble, and reusable cement-based composite formwork that can be easily disassembled. However, existing compression molding machines still have many shortcomings in the production process of cement-based composite formwork, which has prompted us to develop a new type of compression molding machine to overcome the limitations of existing technology.

[0003] I. Existing technical solutions and their shortcomings

[0004] 1. Lack of edge protection technology

[0005] During the use of cement-based composite formwork that requires no dismantling, the edges are susceptible to impact and wear, leading to formwork damage. However, existing molding machines lack effective means of protecting the formwork edges. During the curing process of cement-based materials, due to the shrinkage and expansion characteristics of the material, the edges are often more prone to cracking and damage. Existing molding machines fail to provide specific protective measures for this issue, resulting in a significant reduction in the durability and stability of the formwork edges.

[0006] 2. Low material transfer efficiency

[0007] In the production process of cement-based building non-removable composite formwork, the efficiency of material transfer directly affects production efficiency. However, existing molding machines are often inefficient in material transfer. On the one hand, the existing equipment does not have a tight enough connection between material metering, conveying, and molding, resulting in material waste and transfer delays. On the other hand, the existing equipment lacks effective mechanical linkage control methods during material transfer, making it difficult to achieve accurate material transfer and efficient utilization.

[0008] Furthermore, during the preparation of the non-removable composite formwork, the mortar material undergoes a hydration reaction, leaving some residual moisture. This moisture often occupies space in traditional processes, thus weakening the formwork's strength. To ensure the formwork's molding quality, a high-pressure press is necessary for drainage. However, unfortunately, existing molding equipment lacks an effective filtration mechanism, failing to prevent the mortar material from being discharged along with the press-filtered water. We have conducted a comprehensive and in-depth analysis to address this significant technical deficiency.

[0009] In response to the problem that existing composite formwork production lines lack filtration in their molding equipment, resulting in the unavoidable discharge of mortar materials along with the filter water, we conducted an in-depth defect analysis. The summary is as follows: Existing composite formwork production lines have significant defects in the molding process, primarily stemming from the lack of an effective filtration mechanism in the molding equipment. This defect leads to multiple problems, primarily manifested in resource waste and increased costs. During molding, a large amount of mortar material, rich in valuable resources such as cementitious materials and aggregates, is discharged along with the filter water. This loss not only represents a direct waste of building materials but also forces companies to increase raw material procurement, thereby raising production costs. Simultaneously, the filter water containing impurities cannot be directly recycled, further wasting water resources.

[0010] Environmental pollution is another major problem. The direct discharge of untreated filter water containing mortar materials poses a serious threat to surrounding water bodies. Harmful substances such as chemical solvents and heavy metals in the water can have long-term effects on water quality and damage aquatic ecosystems. If the filter water seeps into the soil, it will also pollute the soil, affecting crop growth and soil ecological balance, and ultimately threatening human food safety.

[0011] In terms of product quality, the loss of mortar material leads to uneven composition of the molded composite formwork, potentially impairing its mechanical properties and service life. Furthermore, the lost material may create voids, cracks, and other surface defects during molding, severely reducing the market competitiveness of the composite formwork. Production efficiency is also affected. Prolonged operation of molding equipment in an environment containing large amounts of mortar material easily causes wear and blockages, increasing equipment maintenance costs. Extended downtime due to equipment blockages or malfunctions further reduces production efficiency, impacting the company's economic benefits.

[0012] More seriously, this deficiency also makes existing compression molding equipment perform poorly in terms of environmental protection and sustainability. With increasing environmental awareness and stricter environmental regulations, equipment lacking filtration capabilities can no longer meet environmental requirements, limiting its application and promotion in the market. In the context of a circular economy and resource conservation, the inability to effectively recycle and reuse lost mortar materials and water resources makes this technology particularly outdated and unsustainable.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0038] Please see Figs. 1 to 4A compression molding machine includes a base 11, with columns 12 installed at the four corners of the base, an upper beam 13 installed on the upper part of the columns, a slider 14 installed on the columns, and a sealing mold frame 15 installed on the slider. The upper end of the sealing mold frame is connected to a sealing mold cavity hydraulic cylinder 16, and a mold core 17 is provided inside the sealing mold frame. The upper end of the mold core is connected to a forming hydraulic cylinder 18 that drives the mold core to move up and down. A movable lower mold moving assembly 19 is installed on the base, and a lower mold 191 is fixedly installed on the movable lower mold moving assembly. A guide rail 192 extends from the base toward the compression molding machine, and a drive cylinder 193 is installed at the outer end of the guide rail. The drive cylinder is connected to the lower mold moving assembly 194, and the lower mold moving assembly reciprocates along the guide rail under the drive of the drive cylinder. The design of the compression molding machine 1 fully considers the actual needs of template production. From the base 11 to the column 12, the upper beam 13, the slider 14, and the edge sealing mold frame 15, a stable yet flexible framework is formed. Driven by the edge sealing mold cavity hydraulic cylinder 16, the edge sealing mold frame 15 enables fast and accurate edge sealing operations, providing solid protection for the edges of the template and preventing cracking or damage during subsequent use. Simultaneously, the mold core 17 moves up and down under the drive of the forming hydraulic cylinder 18, ensuring precise forming of the template's internal structure and meeting the stringent requirements for template strength, flatness, and dimensional accuracy.

[0039] Guided precisely by the guide rail 192, the lower mold reciprocates along the guide rail under the powerful push of the drive cylinder 193, much like a "carrier" on a precise production line. This design primarily enables the lower mold to move back and forth between the metering machine and the molding machine, ensuring seamless material transfer from the metering machine to the molding machine. This efficient material transfer method not only improves production efficiency but also guarantees the continuity and stability of template production, providing a strong guarantee for the large-scale production of non-removable composite templates for construction.

[0040] The lower mold 191 is equipped with drainage holes 1910, which effectively solves the problem of moisture accumulation during material filtration, ensuring smooth water discharge and avoiding impact on the molding quality and subsequent use of the template. The upper surface of the lower mold is equipped with prefabricated steel reinforcement skeleton positioning columns 1911, providing precise positioning for the internal steel reinforcement skeleton and ensuring the structural strength and stability of the template. This design simplifies the installation process of the steel reinforcement skeleton, improves production efficiency, and ensures accurate molding of the template. A rigid support mesh 1912 is laid on the upper surface of the lower mold. The laying of the rigid support mesh 1912, as a rigid support structure, effectively prevents the drainage holes from being blocked, avoids airtightness during pressing, and ensures smooth drainage. A filter cloth 1913 with a mesh size larger than the rigid support mesh is laid on the upper surface of the rigid support mesh, achieving the filtration effect on the material. The filter cloth has a larger mesh size than the rigid support mesh, enabling more precise filtration of moisture and impurities in the material. This ensures that the material is drained away with the filtrate during placement, thereby improving the compactness of the template and the quality of the finished product. The rigid support mesh 1912 and the filter cloth are mounted on the positioning column 1911, and both can be reused.

[0041] The lower mold moving assembly 194 includes a trolley 1941 that moves on a guide rail. A lower mold base 1942 is slidably mounted on the trolley. Elastic reset members 1943, which are elastic rubber pads, are provided around the lower mold base and on the upper surface of the trolley. The lower mold 191 is mounted on the upper surface of the lower mold base. A lower mold base support plate 195 is provided on the trolley corresponding to the lower mold base. A pallet support frame 196 is provided on the trolley adjacent to the automatic pallet feeding and pallet stacking system. A pallet support platform 1960 is provided on the pallet support frame. The pallet support platform and pallet support frame are used to support empty pallets or pallets with non-removable composite templates.

[0042] The drainage holes 1910 on the lower mold 191, the positioning columns 1911 of the precast steel reinforcement skeleton for the non-removable composite formwork, and the rigid support mesh all enhance the load-bearing capacity of the bottom of the formwork, improving its overall stability. The laying of the filter cloth 1913 further contributes to this. In summary, the design of the lower mold 191, through the integration of multiple technical features such as drainage holes, positioning columns, rigid support mesh, and filter cloth, achieves comprehensive optimization of the formwork forming process. This design not only improves production efficiency but also ensures the forming quality and subsequent stability of the formwork, providing reliable technical support for the production of non-removable composite formwork for construction.

[0043] To achieve the recycling of filter water, it is preferable to install a filter water collection pool or collection box at the bottom of the molding machine.

[0044] The pallet support frame is equipped with a pallet longitudinal positioning component 197 and / or a flip-type lateral positioning component 198 adjacent to the automatic pallet feeding and palletizing system. The pallet longitudinal positioning component 197 includes a longitudinal positioning cylinder 1970, which is connected to a positioning plate 1971. The pallet longitudinal positioning component 197 employs a cylinder-driven positioning plate design, with the positioning plate higher than the pallet height. This configuration ensures accurate positioning of the pallet in the longitudinal direction. When the pallet enters or leaves the molding machine, the cylinder drives the positioning plate to quickly reach its position, effectively preventing pallet offset and wobbling, and improving production stability and accuracy.

[0045] The lateral positioning component 198 is a flip-type lateral positioning component, including a lateral positioning cylinder 1980, a lateral positioning cylinder hinged to a positioning column 1981, and the positioning column extending out of the support plate to support the lateral positioning groove 1982 at the end of the platform.

[0046] The flip-type lateral positioning component 198 uses a cylinder to hinge the positioning post, enabling the positioning post to flip. When the pallet exits the molding machine, the positioning post flips to the lateral positioning position under the action of the cylinder, ensuring accurate alignment of the pallet. When the pallet is supplied from the automatic pallet feeding and stacking system, the positioning post flips downward to create clearance, providing space for the pallet to enter smoothly. This design not only improves production flexibility but also effectively avoids collisions and damage to the pallet during the supply process.

[0047] More preferably, a guide post 1990 is provided between the pallet support bracket and the pallet support platform, and a return spring 1991 is fitted on the guide post. This technical feature has the following technical effects:

[0048] Stable support and precise positioning:

[0049] The presence of guide columns ensures the stable vertical movement of the pallet support platform, effectively preventing the pallet from shifting or tilting due to external forces during the support process, thus ensuring that empty pallets or pallets with non-removable composite templates can be accurately placed in the predetermined position.

[0050] The return spring 199 provides continuous elasticity, enabling the pallet support platform to automatically return to its initial position when no external force is applied. This helps maintain the stability and consistency of the entire support system and improves the accuracy of automated operations.

[0051] Shock absorption and protective support plate:

[0052] When the pallet is placed on the pallet support platform, the return spring 197 can act as a buffer, absorbing the impact force when the pallet falls, reducing potential damage to the pallet and the non-removable composite template on it, and extending the service life of the pallet and template.

[0053] During the operation of an automatic palletizing system, minor collisions may occur due to inaccurate mechanical movement or uneven material stacking. The elastic buffering capacity of the return spring can effectively reduce the damage of these collisions to the pallet support frame and the pallet itself.

[0054] More preferably, the lower mold base is provided with a first protective plate 201 around its perimeter.

[0055] More preferably, the trolley is provided with a second protective plate 202 around its perimeter.

[0056] This technical feature effectively prevents external impurities such as mud, water, and dust from entering the sliding fit space between the lower mold base and the trolley. The first and second guard plates act as a barrier, protecting the sliding components from contamination and wear, thus extending the equipment's service life. Simultaneously, it improves equipment reliability, reduces malfunctions and maintenance costs caused by impurities, and ensures the continuity and stability of the production process.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
