Description

Technical Field

[0001] The utility model belongs to the technical field of curbstone production, and in particular relates to a curbstone forming die. Background Art

[0002] In the construction of immersed tube tunnels, in order to prevent vehicles from directly hitting the middle wall from the side and to meet the requirements of pipeline layout, it is necessary to install curbstones on the middle wall of the lanes on both sides of the tunnel. The curbstones are made up of multiple curbstones and are exposed to the outside, so their appearance quality is particularly important.

[0003] The structure of a single curb is as follows Figure 1 As shown, it is heavy and large in size. The curbstone 1 is an asymmetric special-shaped structure, and its cross section is an inverted T-shape as a whole, and has a base 101, a vertical plate 102 protruding from the top surface of the base 101, and a flange 103 protruding from the outside of the base 101. The vertical plate 102, the base 101 and the middle wall of the roadway together form a pipe trench 106, which is used as a passage for various pipelines; the two side surfaces of the curbstone 1 in the length direction are splicing surfaces 104 spliced ​​with other curbstones, and three non-collinear light holes 105 are respectively provided on the two splicing surfaces 104.

[0004] The top surface width of the curbstone 1 upright plate 102 is relatively narrow, about 10 cm. If a conventional ordinary forward forming mold (i.e., the mold is a forming structure in which the curbstone upright plate faces upward and the bottom surface faces downward) is used to cast the curbstone 1 (the mold opening is on top, i.e., the concrete pouring port is on top), on the one hand, a large number of templates are required on the mold, and the templates are assembled many times, and the template assembly requires a large number of bolts for reinforcement, resulting in a complex mold structure, cumbersome template assembly and very low efficiency. In addition, a large number of templates will result in a large number of joints on the surface of the curbstone after casting, and the apparent quality is difficult to guarantee. On the other hand, the use of a mold forming structure with a relatively high and narrow upright plate 102 on top will make the mold opening, i.e., the concrete pouring port, relatively narrow, resulting in difficulty in concrete pouring, and low curbstone molding quality and molding efficiency.

[0012] When the two side templates and the two end templates are rotated in the direction away from the mold core, the curbstone forming mold is opened to demould the cast curbstone.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] refer to Figure 1-Figure 7 As shown, the utility model provides a curbstone forming mold, including a pedestal 2, a mold core 7, two end mold plates 4 and two side mold plates 3. The pedestal 2 includes two H-shaped frame beams arranged in parallel, and the top surface of the pedestal 2 has a supporting surface.

[0039] The mold core 7 is connected to the top surface of the pedestal 2, and the mold core 7 is a shell structure with a cavity as a whole. The outer wall surface of the mold core 7 includes two first molding half cavities arranged opposite to each other, and the cavity surface shape of the first molding half cavity is adapted to the groove surface shape of the pipe groove 106 on the curb 1; more specifically, the cavity surface shape of the first molding half cavity is adapted to the groove surface shape of the pipe groove 106 when the curb 1 is inverted.

[0040] The two end templates 4 are respectively arranged on the outside of the two first forming half-cavities, and the two end templates 4 are respectively rotatably connected to the lower part of the mold core 7. Each end template 4 is provided with a second forming half-cavity on the side close to the mold core 7, and the cavity shape of the second forming half-cavity is adapted to the shape of the wall surface on the side of the curb 1 away from the pipe groove 106; more specifically, the cavity shape of the second forming half-cavity is adapted to the shape of the wall surface on the side of the curb 1 away from the pipe groove 106 when the curb 1 is inverted, that is, the wall surface of the curb 1 away from the pipe groove 106 (including the flange 103 on the outside of the base 101) will be formed on the second forming half-cavity. It can be understood that a plurality of transverse purlins and longitudinal purlins are arranged on the outside of the end template 4 to enhance the structural strength of the end template 4.

[0041] The two side templates 3 are arranged opposite to each other and connected between the two end templates 4, and the mold core 7 is located between the two side templates 3. The two ends of each side template 3 are detachably connected to the same end of the two end templates 4, and the side template 3 is also rotatably connected to the lower part of the mold core 7. Further, the two joint surfaces 104 on both sides of the curb 1 will be formed on the two side templates 3 respectively. It can be understood that a plurality of transverse purlins and longitudinal purlins are also arranged on the outside of the side template 3 to enhance the structural strength of the side template 3.

[0042] When the two side templates 3, the two end templates 4 and the core mold 7 are mutually enclosed and connected, the curbstone forming mold is closed to make the two first forming half cavities and the two second forming half cavities form two independent forming cavities, at which time the top surfaces of the side templates 3, the top surfaces of the end templates 4 and the top surfaces of the core mold 7 are flush; the forming cavity has an upper opening, and the shape of the forming cavity is adapted to the shape of the curbstone 1 when it is inverted; it can be understood by those skilled in the art that the upper opening of the forming cavity is the concrete pouring port, and concrete is poured into the forming cavity through the upper opening of the forming cavity to realize the inverted casting and molding of the curbstone 1; the plane formed by the upper opening of the forming cavity is the bottom surface of the base 101 of the curbstone 1, and therefore, compared with the prior art, the concrete pouring port in this embodiment is more spacious, more convenient for pouring and molding of concrete, and can improve the molding efficiency and molding quality of the curbstone 1, and this set of molds molds two curbstones 1 at a time, further improving the molding efficiency of the curbstone 1.

[0043] When the two side templates 3 and the two end templates 4 are rotated in the direction away from the mold core 7, the curbstone forming mold is opened, and the curbstone 1 after casting can be demolded; it is understandable that before the side templates 3 and the end templates 4 are rotated, the connection between the two should be released first. It is further explained that the rotation angle of the side templates 3 and the end templates 4 can reach up to 35 degrees, thereby fully exposing the curbstone 1 after casting, and it is more convenient to lift the curbstone 1 out of the mold for demolding; it should be noted that because the flange 103 structure on the curbstone 1 is formed on the end template 4, the flange 103 is directly detached from the end template 4 when the end template 4 rotates.

[0044] The above-mentioned schematic embodiment, through the structural arrangement of the mold core 7, the two end mold plates 4 and the two side mold plates 3, realizes the inverted casting molding of the curbstone 1 and the molding of two curbstones 1 with one mold, thereby improving the molding quality and molding efficiency of the curbstone 1, thereby solving the shortcomings of the existing curbstone molding mold, reducing the number of mold plates, significantly reducing the structural complexity of the curbstone molding mold, reducing the number of mold assembly times and the difficulty of assembly, and improving the construction efficiency. In addition, the number of joints on the surface of the curbstone 1 decreases as the number of mold plates decreases, thereby improving the molding appearance quality of the curbstone 1. In addition, through the rotational connection between the two end mold plates 4 and the two side mold plates 3 and the mold core 7, the mold can be opened and closed on all sides, which is convenient for the opening and closing operations of the mold and the demolding of the curbstone 1, thereby improving the molding efficiency of the curbstone 1.

[0045] refer to Figure 2-Figure 7As shown, in some embodiments, the mold core 7 includes a mold core seat 72, two mold core plates 71 and two backing plates. The two mold core plates 71 are arranged back to back, and the two first molding half cavities are respectively located on the two mold core plates 71; the lower ends of the two mold core plates 71 are connected to the mold core seat 72, and a middle partition plate 73 is connected between the upper ends of the two mold core plates 71; the two backing plates are arranged opposite to each other, and each backing plate is connected to the same end of the mold core seat 72, the two mold core plates 71 and the middle partition plate 73; thus, through the arrangement of the mold core seat 72, the middle partition plate 73, the two mold core plates 71 and the two backing plates, the mold core 7 as a whole becomes a shell structure with a cavity. The bottom surface of the mold core seat 72 is connected to the top surface of the pedestal 2; the two end mold plates 4 and the two side mold plates 3 are rotatably connected to the mold core seat 72; when the mold is closed, the two side mold plates 3 are respectively fitted with the two backing plates.

[0046] refer to Figure 2-Figure 7 As shown, in some embodiments, a first locking rod 8 is rotatably connected to the middle portion of the top surface of each end template 4, and the other end of the first locking rod 8 is detachably connected to the top of the middle partition 73; a second locking rod 9 is rotatably connected to the middle portion of the top surface of one side template 3, and the other end of the second locking rod 9 is detachably connected to the top of the other side template 3; it should be noted that the first locking rod 8 and the second locking rod 9 can adopt a cam locking structure, but are not limited to this, and those skilled in the art can flexibly design the structure of the first locking rod 8 and the second locking rod 9 according to actual conditions. Therefore, when the mold is closed, on the basis that the end template 4 and the side template 3 are already connected to each other, the end template 4 and the mold core 7 are locked by the first locking rod 8, so that the two end templates 4 can be reliably crimped on the mold core 7, and the two side templates 3 are locked to each other by the second locking rod 9, so that the two side templates 3 can reliably clamp the mold core 7, even if the side templates 3 and their corresponding support plates are reliably fitted; it can be understood that before the mold is opened, the connection between the first locking rod 8 and the middle partition plate 73, the connection between the second locking rod 9 and a short plate, and the connection between the side template 3 and the end template 4 are first released, and then the side template 3 and the end template 4 are rotated outward, and the first locking rod 8 and the second locking rod 9 are driven to rotate synchronously until the mold opening is completed. At this time, the first locking rod 8 and the second locking rod 9 need to be further rotated to leave space for lifting the curb 1. This illustrative embodiment avoids unfavorable conditions such as loose mold closing or mold expansion during concrete pouring by setting the first locking rod 8 and the second locking rod 9, ensures reliable locking between the mold structures after the mold is closed, ensures the stability of the mold structure during concrete pouring, and further ensures the stability of the molding quality of the curbstone 1.

[0047] refer to Figure 2 , Figure 3 , Figure 5 , Figure 7As shown, in some embodiments, a plurality of rotating arms 16 are convexly provided on the bottom surface of each end mold plate 4 and side mold plate 3, and a bracket 15 corresponding to the rotating arms 16 is provided on the core seat 72, and each rotating arm 16 is rotatably connected to the corresponding bracket 15 via a rotating shaft, so that each end mold plate 4 and side mold plate 3 are rotatably connected to the core seat 72. This exemplary embodiment refines the design of the rotating connection structure between the end mold plate 4 and the core seat 72, and between the side mold plate 3 and the core seat 72, thereby realizing the design of a mold structure that can be opened and closed on all sides.

[0048] refer to Figure 2 As shown, in some embodiments, a plurality of support plates 18 are protrudingly provided on the bottom surface of each end template 4 and side template 3, and a support seat 17 corresponding to the support plates 18 is provided on the core seat 72; when the mold is closed, each support plate 18 is crimped onto the corresponding support seat 17, thereby supporting the end template 4 and the side template 3, and enhancing the overall structural stability of the mold after closing the mold.

[0049] refer to Figure 2 , Figure 4 As shown, in some embodiments, each light hole 105 on each side template 3 corresponding to the joint surface 104 of the curb 1 is provided with a pin 13 that matches the light hole 105; it can be understood that the pin 13 is used to form the light hole 105 on the curb 1, and the light hole 105 is used as a lifting hole when the curb 1 is lifted and demolded. Further, the pin 13 can be a conical pin; when the mold is opened, the conical pin can be directly removed from the light hole 105 of the curb 1 when the side template 3 rotates.

[0050] refer to Figure 2-Figure 3 As shown, in some embodiments, a hanging plate 12 is installed on the outer side of each side template 3 corresponding to each pin 13, and the hanging plate 12 is connected to the side template 3 through a bolt 14; one end of the pin 13 passes through the side template 3 and is connected to the hanging plate 12; a hanging hole is provided on the hanging plate 12; thus, through the arrangement of multiple hanging plates 12, it is convenient to lift and transport the mold as a whole.

[0051] refer to Figure 2 , Figure 3 , Figure 6 , Figure 7As shown, in some embodiments, an air inlet 5 connected to the cavity of the mold core 7 is opened at the upper part of one side template 3, so that external steam is sent into the cavity of the mold core 7 through the air inlet 5; and an air vent 6 connected to the cavity of the mold core 7 is opened at the lower part of the other side template 3, so that the gas in the cavity of the mold core 7 is discharged outward through the air vent 6. Further, the position of the air inlet 5 corresponds to the upper part of the cavity of the mold core 7, and the position of the air vent 6 corresponds to the lower part of the cavity of the mold core 7, that is, the position of the air inlet 5 is higher than the position of the air vent 6, which is conducive to the full diffusion of steam in the cavity of the mold core and the effective use of heat energy; it can be understood that the air inlet 5 and the air vent 6 also penetrate the mold core 7 back plate respectively. In this exemplary embodiment, by setting the air inlet 5 and the air vent 6, external steam can be introduced into the cavity of the mold core 7, the mold temperature is increased, and the setting speed and strength of the concrete in the mold are increased by steam curing, thereby improving the molding efficiency and molding quality of the curb 1.

[0052] refer to Figure 2 , Figure 3 , Figure 5 As shown, in some embodiments, an end of the end template 4 close to the side template 3 is provided with two upper and lower lock buckles 11 to be detachably connected to the side template 3 to ensure the stability of the connection between the end template 4 and the side template 3 and the convenience of disassembly and assembly.
