Description

Technical Field

[0001] This utility model relates to the field of manhole mold technology, and in particular to a manhole mold with high efficiency in mold opening. Background Technology

[0002] Manhole molds consist of an inner mold and an outer mold. When manufacturing cement components, mud is poured into the space between the inner and outer molds, then compacted, and left to solidify before the mold is opened and the cement component is removed.

[0003] There are generally two ways to open the mold between the templates in the current external mold: one is to use multiple bolts and nuts to open the mold, and the other is to install multiple clips and use auxiliary tools such as metal rods to gradually open each clip to complete the mold opening. Regardless of the method, it will take a lot of time to open the mold. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: unlocking and opening the mold one by one takes a lot of time, and to propose a highly efficient manhole mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency manhole mold includes a base plate, on which an outer mold and an inner mold are provided. The outer mold includes a template one and a template two. A self-locking assembly is provided between the template one and the template two. The self-locking assembly includes multiple U-shaped fixing plates fixed on the template one and multiple sets of fixing brackets welded to the template two. A central spindle is rotatably connected to each fixing bracket. Multiple tension plates are fixedly connected to the central spindle. A connecting plate is rotatably connected to each tension plate. A bolt is welded to one end of each connecting plate away from the tension plate. A lever is also fixedly connected to the central spindle. A linkage rod is welded to each connecting plate.

[0007] Preferably, the tensioning plate has a U-shaped cross-section and two through holes. One of the through holes is penetrated by the central spindle, and the other through hole is fixedly connected to a short pin, which is rotatably connected to the connecting plate.

[0008] Preferably, the first template is threaded with a limiting pin, and the second template is provided with a matching limiting hole.

[0009] Preferably, the base plate is fixedly connected to a plurality of concave plates, each of which is rotatably connected to a fixing pin, and both the base plate and the outer mold are provided with slots for the fixing pins to enter.

[0010] Preferably, a baffle for limiting the fixing pin is fixedly connected to the concave plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The entire locking mechanism can be opened in just a few seconds during mold opening, thus saving mold opening time and improving mold opening efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0020] Reference Figures 1-4 A high-efficiency manhole mold includes a base plate 10, on which an outer mold 1 and an inner mold are mounted. The outer mold 1 includes a template one and a template two, with a self-locking assembly between the template one and template two. For example, template one and template two are both V-shaped and together form a cube. The shape of the outer mold 1 can be customized according to actual conditions. The self-locking assembly includes multiple U-shaped fixing plates 3 fixed to template one and multiple sets of fixing brackets 2 welded to template two. Figure 1As shown, the design is connected end to end. Each fixed bracket 2 is rotatably connected to a central spindle 8. Multiple tension plates 9 are fixedly connected to the central spindle 8. Each tension plate 9 is rotatably connected to a connecting plate 7. The cross-section of the tension plate 9 is set in the shape of an 8. The tension plate 9 is provided with two through holes. One through hole is penetrated by the central spindle 8. The other through hole is fixedly connected to a short pin. The 8-shaped setting can expand the stroke of the connecting plate 7, making it easier for the workers to remove the bolt 5 from the U-shaped fixed plate 3 to realize mold opening. The short pin is rotatably connected to the connecting plate 7. A bolt 5 is welded to the end of each connecting plate 7 away from the tension plate 9. A lever 6 is also fixedly connected to the central spindle 8. A linkage rod 4 is welded to each connecting plate 7.

[0021] When the outer mold 1 is closed, the lever 6 is close to the outer surface of the template 2, and the bolt 5 is located inside the U-shaped fixing plate 3, which restricts the template 1, thus achieving self-locking of the stroke.

[0022] When opening the mold, manually pull lever 6 to rotate the central spindle 8, which in turn rotates the tension plate 9. As the tension plate 9 rotates, it causes the connecting plate 7 to move. Figure 2 From the perspective of the connecting plate 7, the movement is to move to the right, so that the bolt 5 is disengaged from the fixed bracket 2, and then the linkage rod 4 is pulled outward, so that the connecting plate 7 and the bolt 5 are completely disengaged from the template. In this way, the locking part can be opened within a few seconds, thereby saving the mold opening time and improving the mold opening efficiency.

[0023] When closing the mold, press the linkage rod 4 in the opposite direction, and then rotate the lever 6 in the opposite direction to complete the mold closing.

[0024] Template 1 is threaded with a limit pin 12, and template 2 is provided with a matching limit hole. When closing the mold, template 1 and template 2 are directly closed, and then the limit pin 12 is inserted into the limit hole to complete the mold closing. This makes it easy for template 1 and template 2 to be aligned.

[0025] The base plate 10 is fixedly connected to multiple concave plates 13, and each concave plate 13 is rotatably connected to a fixing pin 11. Both the base plate 10 and the outer mold 1 are provided with slots 15 for the fixing pins 11 to enter. A baffle 14 is fixedly connected to the concave plate 13 to limit the fixing pins 11. When pulling the template one or template two outward, it is only necessary to rotate the fixing pins 11 downward. The function of the baffle 14 is to limit the rotation angle of the fixing pins 11 to prevent the fixing pins 11 from rotating too much, which would be not conducive to lifting upward when closing the mold. One end of the fixing pin 11 is provided with a stop, the diameter of which is larger than that of the slot 15, which is used to press against the outer mold 1 to make the outer mold 1 and the base plate 10 more tightly.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
