[0002] In municipal construction, road paving is often required. This involves not only paving bricks but also standard components such as curb stones. Curb stones are strip-shaped objects made of stone or concrete, used on the road surface to distinguish the boundaries between carriageways, sidewalks, green spaces, medians, and other parts of the road, playing a role in ensuring the safety of pedestrians and vehicles and ensuring the neatness of the road edges.

[0003] Concrete components such as curb stones are mainly produced through concrete production, currently mostly using wet-process brick production lines. In actual production, the mixed concrete needs to be poured into molds, then compacted to squeeze out the water, and finally demolded to remove the concrete component from the mold for subsequent curing.

[0004] However, the existing curbstone molds have a fixed internal cavity size. When casting curbstones of different sizes, the cavity size cannot be changed, thus the forming size of the curbstones inside the mold cannot be changed, which affects the production efficiency of curbstones, resulting in poor flexibility and practicality, and has certain limitations. In addition, the existing curbstone molds have poor drainage performance and cannot drain the water generated during the forming process in a timely manner. Therefore, it is urgent to design a lower mold device for a wet forming machine to solve the above problems. Utility Model Content

A right side plate 2-3 is installed on the inner side of the right long-side core structure 2-2, and a left side plate 2-4 is installed on the inner side of the left long-side core structure 2-6. An adjustment unit 1 and an adjustment unit 2, detachably connected to the mold outer frame assembly 1, are provided between the right side plate 2-3 and the left side plate 2-4 for adjusting the molding cavity of the mold core assembly 2. A rear upper sealing plate 2-10 and a rear lower sealing plate 2-16 are detachably connected to the top and bottom surfaces of the adjustment unit 1, respectively; a front upper sealing plate 2-9 and a front lower sealing plate 2-15 are detachably connected to the top and bottom surfaces of the adjustment unit 2, respectively. Both the right side plate 2-3 and the left side plate 2-4 are made of chrome-molybdenum steel.

[0024] In addition, a right upper sealing plate 2-8 and a right lower sealing plate 2-1 are installed on the top and bottom surfaces of the right long side core structure 2-2, respectively. A left upper sealing plate 2-7 and a left lower sealing plate 2-5 are installed on the top and bottom surfaces of the left long side core structure 2-6, respectively. The aforementioned front upper sealing plate 2-9, rear upper sealing plate 2-10, right upper sealing plate 2-8, and left upper sealing plate 2-7 are all detachably connected to the mold outer frame assembly 1 by bolts. The aforementioned front lower sealing plate 2-15, rear lower sealing plate 2-16, left lower sealing plate 2-5, and right lower sealing plate 2-1 are all detachably connected to the mold outer frame assembly 1 by bolts.

[0025] See further Figure 6 The aforementioned adjustment unit 1 includes a rear side plate 2-11 detachably connected to the mold outer frame assembly 1, and an adjustment component 2-12 is installed on the inner side of the rear side plate 2-11. The adjustment component 2-12 includes an adjustment block connected to the rear side plate 2-11, and a plate is fixedly attached to the inner side of the adjustment block. Furthermore, both the rear side plate 2-11 and the plate fixedly attached to the inner side of the adjustment block are made of chrome-molybdenum steel.

[0026] Adjustment unit two includes a front side plate 2-14 detachably connected to the mold outer frame assembly 1.

[0027] In addition, the right long side core structure 2-2 and the left long side core structure 2-6 mentioned above have the same structure, both including two long plates arranged opposite each other, and several short ribs arranged in parallel are fixed between the two long plates. Through the above arrangement, the structural strength of the long side core structure can be improved.

[0028] like Figure 6As shown, several supporting protrusions 2-17 protruding towards the center of the mold core assembly 2 are provided at the inner edges of the lower right sealing plate 2-1, lower left sealing plate 2-5, lower front sealing plate 2-15, and lower rear sealing plate 2-16.

Several drainage connectors 3-5 communicating with the water outlet passage 3-3 are installed on the top surface of the pressing drainage unit. In addition, a manifold is installed between the pipe connector installed on the water outlet 4 and the several drainage connectors 3-5.

[0030] The aforementioned pressure head main structure 3-6 includes an outer frame structure composed of several vertical plates, and several inner reinforcing plates arranged in parallel are fixedly connected to the inner area of ​​the outer frame structure.

[0031] See further Figure 4 and Figure 5 The aforementioned press-drainage unit includes a second press head main plate 3-2 fixedly connected to the bottom surface of the main press head structure 3-6. A first press head main plate 3-1 adapted to the molding cavity of the mold core assembly 2 is detachably connected to the second press head main plate 3-2 by bolts. Water passage grooves 3-8 are opened on the mating surfaces of the first press head main plate 3-1 and the second press head main plate 3-2. The two sets of water passage grooves 3-8 are connected to form a water outlet passage 3-3.

[0032] The aforementioned water passage 3-8 includes several confluence holes on the pressure head main plate and radial grooves connected to each confluence hole. The drain connector 3-5 is connected to the confluence holes. The several confluence holes on the pressure head main plate 3-1 and the several confluence holes on the pressure head main plate 3-2 are connected one-to-one to form a water outlet connected to the drain connector 3-5. Several patterned holes are formed on the bottom surface of the pressure head main plate 3-1; in this embodiment, these are several circular and several square patterned holes. This arrangement creates several anti-slip protrusions on the surface of the curbstone.

[0033] A pipe is installed on the water outlet 4 via a connector, and a valve assembly is installed on the pipe. The valve assembly is connected to the vacuum water suction machine. A pipe is installed between the drain connector 3-5 and the connector installed on the water outlet 4, and is connected to the aforementioned manifold via the pipe.

[0034] like Figure 3 As shown, the aforementioned mold outer frame assembly 1 includes a lower outer frame 1-1 and an upper outer frame 1-2 that are connected and mounted together. The upper left sealing plate 2-7, upper right sealing plate 2-8, upper front sealing plate 2-9, and upper rear sealing plate 2-10 are all detachably connected to the upper outer frame 1-2 by bolts. The lower right sealing plate 2-1, lower left sealing plate 2-5, lower front sealing plate 2-15, and lower rear sealing plate 2-16 are all detachably connected to the lower outer frame 1-1 by bolts. Several corresponding positioning through holes are provided on both the lower outer frame 1-1 and the upper outer frame 1-2, and several threaded holes are provided around each positioning through hole. Through these positioning through holes and threaded holes, the mold outer frame assembly 1 can be positioned and installed by passing it through a positioning pin and then positioning it using bolts inserted through the cover plate and threaded holes.

[0035] Working principle:

[0036] Based on the shape and size of the curbstone, select the corresponding right long side core structure 2-2, left long side core structure 2-6, adjustment unit one, and adjustment unit two. Use bolts to detachably install the right long side core structure 2-2, left long side core structure 2-6, adjustment unit one, and adjustment unit two onto the mold outer frame assembly 1. Then, use bolts to install the corresponding sealing plates onto the corresponding left and right long side core structures and mold outer frame assembly 1, as well as adjustment units one, two, and mold outer frame assembly 1. Then, based on the shape and size of the curbstone, select the corresponding pressure head main plate one 3-1 and install it onto pressure head main plate two 3-2, forming the water outlet passage 3-3.

[0037] In actual operation, the outer frame assembly 1 of the mold is installed on the molding machine. During the molding operation, the corresponding inner cavity bottom plate is slidably installed in the molding cavity of the inner core assembly 2 of the mold, and the lower port of the inner core assembly 2 of the mold is sealed. Then, the material is injected into the molding cavity of the inner core assembly 2 of the mold, and then the pressure head assembly 3 moves down into the molding cavity of the inner core assembly 2 of the mold to extrude and mold the material. At the same time, the vacuum water suction machine controls the water outlet pipe to perform water suction. Under the action of the main plate of the pressure head 3-1, the drain connector 3-5 and the manifold installed on it discharge excess water through several drain suction ports 3-4 and water outlet passage 3-3. After the above molding operation is completed, the pressure head assembly 3 is lifted by the linear drive component, so that the pressure head assembly 3 moves up and resets to disengage from the inner core assembly 2 of the mold, so that the molding machine can transfer the molded material in the corresponding inner core assembly 2 of the mold, thereby facilitating the extrusion and demolding of the molded material.
