The closing structure of a grass brick curing mold

Abstract

This utility model discloses a closing structure for a grass-planting brick curing mold, relating to the field of brick manufacturing technology. It includes an upper mold and a lower mold, with the upper mold engaging at the upper end of the lower mold. A connecting rod is fixedly connected to the upper edge of the upper mold, penetrating through the upper mold. An annular groove is formed on the outer wall of the connecting rod. A pressing mechanism is included, comprising a locking block, eccentric wheels, and a pull rod. The locking block engages at the upper end of the connecting rod, with two eccentric wheels rotatably connected to both sides of the locking block. The two ends of the pull rod are connected to the outer walls of the two eccentric wheels, respectively, for applying downward pressure to the upper mold. A pad is installed at the upper end of the upper mold through a through-hole to increase the pressure area. By engaging the upper mold with the lower mold and applying downward pressure through the pressing mechanism, the upper and lower molds close evenly, solving the problems of inaccurate alignment and uneven closing pressure that easily occur with existing molds during closing.

Description

Technical Field

[0001] This utility model relates to the field of brick manufacturing technology, specifically to the closing structure of a grass-planting brick curing mold. Background Technology

[0002] Grass pavers are an eco-friendly building material primarily used in landscaping, urban landscaping, and road paving. Their structural design allows lawns or other plants to grow within the gaps between the pavers, achieving a combination of greening and paving, while also providing excellent permeability and ecological functionality. Grass pavers not only beautify the environment but also effectively reduce rainwater runoff, mitigate the urban heat island effect, and improve air quality. The production process of grass pavers mainly includes raw material selection, batching and mixing, molding, curing, inspection, and packaging.

[0003] The molding mold for grass pavers consists of upper and lower molds. Raw materials are first placed into the lower mold, then compressed by the upper mold, and finally heated and solidified to form a paver blank. However, because the grass pavers have openings for rainwater flow, both the upper and lower molds also have central pillars for these openings, and these pillars must be aligned and joined. However, if the alignment of the upper and lower molds is not accurate when they are closed, uneven molding may occur, affecting the size and shape of the pavers. This alignment error may lead to unstable product quality. Furthermore, uneven pressure distribution during mold closure may result in insufficient material compaction in certain areas, leading to air bubbles or uneven density, affecting the strength and durability of the pavers. To address these issues, a closure structure for the curing mold of grass pavers is provided. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4This embodiment provides a closing structure for a grass brick curing mold. The mold includes an upper mold 1 and a lower mold 2, with the upper mold 1 engaging with the lower mold 2. The lower mold 2 includes a central pillar and two separate molds, which are joined together, with the central pillar engaging between the two molds. In use, brick material is injected into the mold hole of the lower mold 2, and the upper mold 1 is then placed on top of the lower mold 2. The material is shaped by the extrusion of the upper mold 1, and finally, heating the mold solidifies the material into a brick blank.

[0017] Regarding the connection between the upper mold 1 and the lower mold 2, a connecting rod 3 is fixedly connected to the upper corner of the lower mold 2, such as... Figure 2 As shown, the lower mold 2 is connected to four connecting rods 3, which are evenly arranged in a circular array around the central column. The upper mold 1 has through holes that match the connecting rods 3. After the upper mold 1 is placed on the lower mold 2, the connecting rods 3 pass through the through holes, positioning the upper mold 1 and ensuring that the upper mold 1 and the lower mold 2 are precisely engaged.

[0018] The outer wall of the part of the connecting rod 3 extending from the upper end of the upper mold 1 has an annular groove, such as... Figure 1 As shown, a pressing mechanism 4 is installed on the connecting rod 3 via an annular groove. Specifically, the pressing mechanism 4 includes a locking block 41, an eccentric wheel 42, and a pull rod 43. One end of the locking block 41 has a locking groove, and the locking block 41 engages with the upper end of the connecting rod 3 through the locking groove. The lower end of the locking block 41 engages within the annular groove of the connecting rod 3, preventing the locking block 41 from moving upward and disengaging from the connecting rod 3. Figure 3 and Figure 4 As shown, rotating shafts are fixedly connected to both sides of the locking block 41. Two eccentric wheels 42 are provided, and rotating holes are opened on the end faces of the eccentric wheels 42 near the edges. The eccentric wheels 42 are sleeved on the rotating shafts of the locking block 41 through the rotating holes, so that the two eccentric wheels 42 are rotatably connected to both sides of the locking block 41. The two ends of the pull rod 43 are fixedly connected to the outer walls of the two eccentric wheels 42 respectively.

[0019] When in use, pulling the lever 43 drives the eccentric wheel 42 to rotate. After the eccentric wheel 42 moves away from the outer wall of the rotating hole and fits against the upper mold 1, it applies downward pressure to the upper mold 1, thereby driving the upper mold 1 and the lower mold 2 to close together and squeeze the raw material inside the mold.

[0020] like Figure 1 and Figure 2As shown, a pad 11 is fixedly connected to the through hole at the upper end of the upper mold 1. When the eccentric wheel 42 rotates, the eccentric wheel 42 contacts the pad 11. The pad 11 is made of high-strength metal, which increases the force application area of ​​the eccentric wheel 42 on the upper mold 1, thereby dispersing the pressure applied to the upper mold 1. This design not only improves the uniformity of force application but also effectively prevents the eccentric wheel 42 from causing damage to the upper mold 1 during operation (wear and extrusion damage), extending the service life of the mold. At the same time, the strength and rigidity of the pad 11 ensure reliability under high-load working conditions, further enhancing the safety and stability of the overall structure.

[0021] Compared to the existing connection of two molds, the simultaneous pressing of the upper mold 1 by four pressing mechanisms 4, which causes the upper mold 1 and lower mold 2 to close, allows for better control of the pressure distribution during mold closure. This ensures that each part is subjected to uniform pressure, thereby improving the density and molding quality of the bricks. The connecting rod 3 and the pressing mechanism 4 can also achieve higher alignment accuracy, reducing alignment errors between the upper and lower molds, ensuring precise mold fit during molding, and improving the size and shape consistency of the product.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
