Description
Technical Field
[0001] The utility model relates to the technical field of prefabricated concrete pipes, in particular to a modular mould for prefabricated concrete pipes. Background Art
[0002] Precast concrete pipe is a kind of precast concrete product widely used in social and economic construction. It has a high degree of standardization and is suitable for mass production. According to the needs of actual projects and the requirements of relevant product standards, precast concrete pipe can be produced by a variety of molding processes. Among them, the products produced by vertical vibration molding process have the characteristics of stable quality and performance, easy to master the process, and good appearance quality.
[0003] The vertical vibrating molding process is used to produce precast concrete pipes, which requires a special molding mold. The existing precast concrete pipe molding mold generally consists of four parts: bottom mold, inner mold, outer mold and top cover. Figure 1 , Figure 2 As shown; each part of the mold is usually made of steel and is manufactured into a separate entity by machining, welding, etc.
[0004] With the continuous changes in engineering requirements, the models and specifications of precast concrete pipes are becoming more and more diversified. The changes in models and specifications generally include changes in the length of the pipe section (usually each section of the pipe is 1m-3m long) and changes in the interface type (including: single rubber ring interface, double rubber ring interface, steel socket interface, socket-type interface, etc.).
[0005] Due to the above changes, the type of forming molds must also change accordingly. Since the existing commonly used forming molds are composed of four integral parts, the above changes require the same caliber products to be equipped with forming molds of different lengths and different interface sizes, which causes manufacturers to bear huge cost pressure in terms of mold investment and seriously affects production efficiency. In addition to the above problems, the existing commonly used molds also have the following inconveniences in use: when the mold is used, the mold closing procedure is: cleaning the bottom mold-hoisting the inner mold-hoisting the steel cage-hoisting the outer mold-hoisting the top cover; the mold removal procedure is: hoisting off the top cover-hoisting off the outer mold-hoisting off the inner mold-hoisting off the pipe. In the above procedures, except for "cleaning the bottom mold", all operations require the use of a crane, which makes the crane used too frequently during the production process; the crane used in production is generally a bridge crane or a gantry crane, which has a slow travel speed. In addition, different tooling is required to hoist different objects, and there is a problem of frequent tooling changes. Therefore, the excessive use frequency of the crane will further reduce production efficiency. Utility Model Content

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0031] Example 1
[0032] The following is combined with Figure 1-4 The utility model is further described as follows:
[0033] In the prior art, a precast concrete pipe is produced by a vertical vibrating molding process, which requires a special molding mold. The existing precast concrete pipe molding mold 20 generally consists of a bottom mold 21, an inner mold 22, an outer mold 23 and a top cover 24. Figure 1 , Figure 2 The various parts of the mold are usually steel parts, and are manufactured into separate entities by machining, welding, etc.
[0034] The utility model provides a modular mold 10 for prefabricated concrete pipes. Figure 3-4 The modular mold 10 for prefabricated concrete pipes includes an outer mold 200, an inner mold 300, a top cover 100 arranged above the inner mold 300, a socket module 500, a bottom mold bottom plate 600, a bottom support plate 700, a bottom mold support block 900, a socket module 400 and an outer mold slide rail 800.
[0035] The outer mold 200 is arranged around the inner mold 300, and a casting cavity 220 for pouring concrete is formed between the outer mold 200 and the inner mold 300. The outer mold 200 includes two symmetrically arranged outer mold unit blocks 210, and the cross section of the outer mold unit blocks 210 is arc-shaped. The two outer mold unit blocks 210 are detachably connected and can be close to each other, close to each other, or far away from each other.
[0036] Specifically, in this embodiment, the outer mold slide rail 800 is disposed below the outer mold 200, the length direction of the outer mold slide rail 800 is parallel to the relative movement direction of the two outer mold unit blocks 210, and the outer mold unit blocks 210 are slidably connected to the outer mold slide rail 800. The outer mold unit blocks 210 are provided with a pulley 810, which is embedded in the outer mold slide rail 800 and slidably connected to the outer mold slide rail 800.
[0037] In this embodiment, the outer mold 200 and the inner mold 300 are arranged on the bottom supporting plate 700, the socket module 500, the bottom mold base plate 600 and the bottom mold support block 900 are all arranged in the casting cavity 220, and the bottom mold support block 900 is arranged between the bottom mold base plate 600 and the bottom supporting plate 700, and the socket module 500, the bottom mold base plate 600, the bottom mold support block 900 and the bottom supporting plate 700 are detachably connected.
[0038] The bottom support plate 700 is a circular module arranged at the bottom of the mold, and its function is to serve as the bottom reference plane of each mold module, on which the inner mold 300, the combination of the socket module 500 and the bottom mold bottom plate 600, and the outer mold 200 are placed. When the precast concrete pipe is produced in the longest size, the bottom support plate 700 can be fixed with the combination of the socket module 500 and the bottom mold bottom plate 600 by bolts; when the precast concrete pipe is produced in a size smaller than the longest size, it serves as the bearing base of the bottom mold support block 900 to bear the upper weight.
[0039] In this embodiment, the bottom mold base plate 600 is a circular module, which is placed at the bottom of the bell module 500 and can be assembled with the bell module 500 by bolts. Its inner side matches the outer wall size of the inner mold 300, and its outer side matches the inner wall size of the outer mold 200. When the length of the product to be produced needs to be changed, it can be raised together with the combination of the bell module 500, and the bottom is stabilized and carries the upper weight by the bottom mold support block 900.
[0040] In this embodiment, the bottom mold support block 900 serves as a supporting structure for the lower part of the combination of the socket module 500 and the bottom mold bottom plate 600 when producing products that are shorter than the maximum length of the mold. It is used to stabilize and transfer the upper weight (including the weight of the combination of the socket module 500 and the bottom mold bottom plate 600 and the precast concrete pipe casting body). The length of the bottom mold support block 900 can be selected according to the length requirements of the product. When the maximum length of the mold is used to produce products, the bottom mold support block 900 is not needed.
[0041] In this embodiment, the socket module 500 is a separate module made according to the shape and size of the socket of the precast concrete pipe, and adopts a full-circle ring design. The outer shape of the socket module 500 is completely consistent with the shape of the socket of the precast concrete pipe, and the inner side is matched with the outer wall size of the inner mold 300. When in use, the socket module 500 can be combined and positioned with the bottom mold bottom plate 600 by bolts. The socket modules 500 on the same set of molds can be configured with multiple different types according to production needs for replacement and use.
[0042] In this embodiment, the socket module 400 is detachably connected to the inner wall of the outer mold 200. The socket module 400 is a separate module made according to the shape and size of the socket of the precast concrete pipe, and adopts a design of two mirror images of each other. The inner shape of the socket module 400 is exactly the same as the shape of the socket of the precast concrete pipe, and the outer side is matched with the corresponding position size of the upper end of the outer mold 200; when in use, the socket module 400 can be combined and positioned with the outer mold 200 by bolts. The socket modules 400 on the same set of molds can be configured with multiple different types according to production needs for replacement and use.
[0043] The modular mold 10 for prefabricated concrete pipes provided in this embodiment is used as follows: first, after customizing the modular mold for a prefabricated concrete pipe product of a certain diameter, select the corresponding socket module 500 and the socket module 400 according to the socket and socket types corresponding to the product, and position and fix them on the bottom mold base plate 600 and the outer mold 200; select the support of corresponding length according to the length of the product pipe section, and position and fix the bottom mold base plate 600 and the socket module 500 assembly; then, adjust the overall level of the mold and keep it stable. Before use, the outer mold 200 is in a separated state, and all working surfaces of the mold (contacting the concrete pipe) are aligned. Then, use a crane to lift the corresponding steel component into the mold. At this time, the steel component is in a state of being sleeved on the outer ring of the inner mold 300 and placed on the socket module 500. After positioning the steel component, close the inner mold 300, and then use a crane to lift the top cover 100 to the top of the inner mold 300; then, manually push the two outer mold unit blocks 210 to move toward each other until they are closed and tightened, and start pouring concrete and curing; finally, after completing the curing, manually loosen the two outer mold unit blocks 210 and push them to be in a separated state, use a crane to lift off the top cover 100, manually loosen the inner mold 300, and use a crane to lift the product away.
[0044] In summary, the modular mold 10 for precast concrete pipes provided in this embodiment can, on the one hand, effectively reduce the dependence on lifting equipment in the production process. During the assembly and disassembly of the molds, there is no need to use lifting equipment for the outer mold 200 and the inner mold 300, which significantly reduces the frequency of use of the lifting equipment, avoids cross-operation of lifting, and improves production efficiency. On the other hand, the modular mold 10 for precast concrete pipes can enable precast concrete pipes of the same diameter to produce products with multiple interface types and multiple pipe section lengths on the same set of molds, avoiding the defect that a set of traditional similar molds can only produce products with one interface type and one pipe section length, and significantly reduces the cost of producing molds.
[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
