[0038] like Figure 1 and Figure 2 As shown, an environmentally friendly marble sawdust curbstone mold includes a base 1, a mold body 2, and a heating device 3. The base 1 supports the entire mold and has a pair of heating devices 3 clamped to the outside of the mold body 2. The mold body 2 is mounted on the base 1 and has an internal cavity 21 adapted to the shape of the curbstone. It consists of a detachable upper template 22, a lower template 23, and a side template 24, with the inner wall coated with polytetrafluoroethylene. The heating device 3 includes heating pipes 31 located on the upper and lower sides of the mold body 2, evenly distributed inside the upper template 22 and at the bottom of the lower template 23, and covered with a heat insulation layer. The heating pipes 31 have typical connecting components at both ends for connecting to an external power source. The upper template 22, the lower template 23, and the side template 24 are connected by bolts 4, which penetrate the outer shell of the upper template 22. The side template 24 has a corresponding mounting groove 25 inside, and a quick-release wrench or pneumatic unlocker can be installed in the mounting groove 25 to quickly release the bolts 4.

[0039] In this embodiment, the structure of this utility model has the following functions in overcoming the shortcomings of the prior art: 1. Base 1

[0040] Support the entire mold: Provide a stable mounting base for the mold body, heating device, etc., to ensure the stability of the processing.

[0041] Integrated heating device: A pair of heating devices 3 are installed on the base, which uniformly heat the marble saw mud inside the mold body 2 through the heating pipes 31 on the upper and lower sides.

[0042] Insulation layer design: The heating device is covered with an insulation layer to reduce heat loss, improve heating efficiency, and reduce energy consumption.

[0043] Addressing the shortcomings of existing technologies:

[0044] Traditional molds lack integrated heating functionality, requiring external equipment, resulting in low efficiency and unstable temperature control. This design integrates a heating device into the base, combined with an insulation layer, to achieve efficient and uniform heating, thereby improving molding efficiency.

[0045] 2. Mold body 2 and detachable structure

[0046] Composition and structure:

[0047] Upper template 22, lower template 23, and side template 24: are connected by bolts 4 to form a cavity 21, the shape of which is adapted to the curbstone.

[0048] High-temperature resistant polytetrafluoroethylene coating: Coated on the inner wall of the mold cavity to prevent sawdust from adhering and facilitate demolding.

[0049] Mounting slot 25: Located inside the side template, it is used to accommodate bolt 4 and quick-release tools such as pneumatic unlockers.

[0050] Modular and detachable design: Quick assembly and disassembly are achieved through bolt connections, facilitating maintenance and replacement of components, significantly reducing maintenance costs and time.

[0051] High-temperature resistant coating: Reduces demolding resistance, prevents damage to the surface of finished products, and improves product quality.

[0052] Addressing the shortcomings of existing technologies:

[0053] Traditional molds have fixed structures, making maintenance difficult. This design simplifies operation and extends mold life through modular combinations and quick-unlocking devices such as tools installed in the slot.

[0054] 3. Heating device 3 and heating tube 31

[0055] Uniform heating: Heating tubes 31 are distributed inside the upper template and at the bottom of the lower template. Through bidirectional heat conduction, the sawdust is heated evenly.

[0056] Typical connection components: The heating element is connected to an external power source at both ends for easy energy supply and temperature control.

[0057] Insulation layer: Reduces heat loss and improves energy efficiency.

[0058] Traditional molds rely on external heating or a single heat source, which can easily lead to localized overheating or uneven heating. This design achieves efficient and uniform heating through a dual heating element layout and a heat insulation layer, shortening molding time and improving the density of the finished product.

[0059] 4. Quick-release design for bolt 4 and mounting slot 25

[0060] Secure connection: Bolt 4 passes through the upper template shell to ensure that all templates of the mold body are tightly fixed.

[0061] Quick unlocking: A quick wrench or pneumatic unlocker can be installed in the mounting slot 25 to release the bolt fixing state with one click, enabling quick mold disassembly.

[0062] Traditional molds use ordinary bolts, which are time-consuming and labor-intensive to disassemble. This design, through the combination of mounting slots and quick-unlocking tools, significantly improves disassembly and assembly efficiency, adapting to the needs of high-frequency production.

[0063] 5. Sealing structure: silicone rubber sealing strip and high-temperature resistant epoxy resin adhesive

[0064] Multiple seals:

[0065] A silicone rubber sealing strip is installed between the side template 24 and the upper template 23. It is resistant to high temperature and has strong elasticity.

[0066] Sealant fills tiny gaps to prevent sawdust leakage.

[0067] A secondary seal is achieved between the side templates using mounting bolts 41 and sealing strips.

[0068] Traditional molds often have poor sealing, leading to material leakage and product defects. This design utilizes a composite sealing solution combining silicone rubber sealing strips and high-temperature resistant adhesive to ensure complete mold sealing during the heating and compaction process, thereby improving the product yield.

[0069] 6. Activity Template 23

[0070] Freely replaceable: The lower template 23 is movable inside the cavity and can be quickly replaced according to different curbstone sizes or shapes.

[0071] Traditional molds have fixed lower templates, which cannot adapt to diverse production needs. This design improves mold flexibility and applicability by using modular lower templates, reducing the cost of repeated purchases.

[0072] Based on the above implementation scheme, the overall technical effects and innovations of this device are as follows:

[0073] Modular and detachable design:

[0074] By using bolted connections, quick-unlocking mounting slots, and movable lower templates, the system enables rapid disassembly and assembly of molds and replacement of components, solving the problems of difficult and costly maintenance of traditional molds.

[0075] High-efficiency heating and energy saving:

[0076] The dual heating tube layout combined with the insulation layer improves heating uniformity and energy efficiency, solving the problems of low heating efficiency and high energy consumption in traditional molds.

[0077] Optimized sealing performance:

[0078] The composite sealing solution of silicone rubber sealing strips and high-temperature resistant adhesive eliminates leakage, improves finished product quality, and solves the material waste caused by poor sealing of traditional molds.

[0079] Flexible adaptation to production needs:

[0080] The movable template and adjustable cavity design allow the mold to adapt to the production of curb stones of different specifications, extending the mold's service life and reducing the company's equipment investment costs.

[0081] Through the synergistic effect of the above structures, the mold achieves significant innovations in terms of ease of maintenance, heating efficiency, sealing performance and production flexibility, effectively solving the core pain points in existing technologies and making it suitable for the efficient recycling of marble sawdust in the field of environmentally friendly building materials.

[0082] like Figure 2 and Figure 3 As shown, the above-mentioned environmentally friendly marble sawdust curbstone mold achieves the function of heating and compacting marble sawdust into curbstone through the following methods: the heating pipe 31 inside the mold body 2 heats the marble sawdust to reach a suitable molding temperature, improving the plasticity and density of the material; a silicone rubber sealing strip is provided between the side template 24 and the upper template 22, which, together with high-temperature resistant epoxy resin, and the side templates 24 are sealed together by mounting bolts 41 and sealing strips, ensuring good sealing of the mold during heating and compaction and preventing sawdust leakage; the lower template 23 is movably located inside the cavity 21 and can be freely replaced, facilitating the adjustment of the internal structure of the mold according to different needs, improving the flexibility and practicality of the mold, thereby efficiently completing the production of curbstone.

[0083] In practical implementation, this device needs to work in conjunction with existing auxiliary devices, such as marble sawdust pretreatment equipment to homogenize the raw materials, ensuring that the moisture content and particle distribution of the sawdust meet the compaction requirements; the shaped curbstone needs to be cured and shaped by external curing equipment to further improve the strength of the finished product. Furthermore, the existing automated control system can be integrated into this device to link the temperature sensor and heating element of the heating device, achieving precise temperature control, while simultaneously adjusting the pressurization frequency of the compaction device and the rotation angle of the rotating device. The selection of key materials for this device also needs to be tailored to engineering requirements; for example, the insulation layer uses ceramic fiber, the high-temperature resistant coating uses polytetrafluoroethylene, the sealing strip uses silicone rubber, and the bolts and mounting grooves use 304 stainless steel to ensure structural stability and durability under high temperature and high pressure conditions.

[0084] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
