Description

Technical Field

[0001] The invention relates to a multi-point RPC drainage ditch maintenance molding die, and belongs to the field of RPC drainage ditch production dies. Background Art

[0002] RPC (reactive powder concrete) drains are prefabricated drainage facilities made of high-strength reactive powder concrete materials, with the remarkable characteristics of light weight, high strength and good durability. RPC drains are mainly used in scenes such as highways, urban roads, cable trenches and green belts to drain accumulated water. The production process of RPC drains is to use special molds to cast concrete. The existing drain ditch maintenance and molding mold can only realize the demoulding of the outer mold, and its inner mold core is usually a fixed structure. After demoulding, there is still a large area of contact between the inner mold core and the finished drain ditch, which makes it difficult to remove the finished drain ditch. If the operation is improper, it may even cause damage to the finished drain ditch. In addition, the existing drain ditch maintenance and molding mold can only form one product at a time, and the production efficiency is low.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN206287420U discloses a resin concrete drainage ditch mold, which, after molding, uses the demoulding handle to pull the male and female molding plates to demould, and then pulls the demoulding handle to demould the side plates, and then removes the product from the core molding plate. The above-mentioned prior art has the following defects: First, only one product can be molded through one curing, and the production efficiency is low; second, because the product still has a large area of contact with the core molding plate when it is taken out, it is difficult to take out the product, and if the operation is improper, it may even cause product damage.

Specific Embodiment

[0029] The following further describes the embodiments of the present invention with reference to the accompanying drawings:

[0030] Embodiment 1:

[0031] As Figures 1 to 10 shown, the multi-point RPC drainage ditch curing and forming mold of the present invention includes a base 15, and a left door plate body 16, a right door plate body 19 and two side door plate bodies 17 are movably connected around the base 15. A plurality of inner mold cores 35 and a plurality of partition bodies 18 are movably connected on the base 15. Each inner mold core 35 and partition body 18 are staggered between the left door plate body 16 and the right door plate body 19, and the number of inner mold cores 35 is one more than the number of partition bodies 18; outer templates 34 are provided on the right side of the left door plate body 16, the left side of the right door plate body 19, and both sides of the partition body 18; the inner mold core 35 includes a mounting plate 1, a frame gantry 13 is fixedly connected to the mounting plate 1, a U-shaped inner mold core plate 11 is fixedly connected to the top of the frame gantry 13, the inner mold core plate 11 has elastic deformation characteristics, and mold frames 12 are fixedly connected to the inner sides of both side walls of the inner mold core plate 11, and both mold frames 12 are connected with mold frame driving mechanisms; end templates 20 corresponding to the inner mold core plates 11 one by one are provided on both side door plate bodies 17, and two outer templates 34, one inner mold core plate 11 and two end templates 20 enclose a product forming cavity.

[0032] In use, high-strength reactive powder concrete is poured into the inner cavity of the product for molding, and then the finished RPC drainage ditch 14 is obtained after curing. When demolding, first open the two side door plates 17, and the end formworks 20 can be separated from the finished RPC drainage ditch 14. Then move the left door plate 16, each inner mold core 35, each partition plate 18 and the right door plate 19, and the outer formworks 34 can be separated from the finished RPC drainage ditch 14. Then, through the action of the mold frame driving mechanism, drive the two mold frames 12 to deflect slightly inward, so as to drive the two side walls of the inner mold core plate 11 to elastically deform and deflect slightly inward, so that the two side walls of the inner mold core plate 11 are separated from the two inner side walls of the finished RPC drainage ditch 14, and then the finished RPC drainage ditch 14 can be removed from the top wall of the inner mold core plate 11.

[0033] Embodiment 2:

[0034] As Figures 1 to 10 shown, on the basis of Embodiment 1,

[0035] Furthermore, the inner mold core plate 11 is an integrally formed stainless steel thin plate, which has high strength, corrosion resistance and good elastic deformation performance. A support block 10 is fixedly connected to the mold frame 12 and is in contact with the bottom of the inner mold core plate 11. The support block 10 can effectively support the bottom wall of the inner mold core plate 11, thereby preventing the bottom wall of the inner mold core plate 11 from deforming under the extrusion of concrete.

[0036] Furthermore, guide blocks 8 are provided on both of the two mold frames 12, and strip-shaped sliding holes 7 corresponding to and adapted to the two guide blocks 8 are provided on the mounting plate 1. Under the cooperation of the strip-shaped sliding holes 7 and the guide blocks 8, the mold frame 12 can be guided in the left-right direction, preventing the mold frame 12 from swinging back and forth, and improving the deflection stability of the mold frame 12.

[0037] Furthermore, a plurality of hinge seats 25 are fixedly connected to the front and rear sides of the base 15, and a connecting frame 26 is hinged to each hinge seat 25. Each connecting frame 26 is fixedly connected to its corresponding side door plate 17. By flipping the side door plate 17, the mold closing and demolding of the end formwork 20 can be realized, and the operation is simple and convenient.

[0038] Furthermore, hanging ears 21 are connected to the front and rear sides of the left door plate 16, the partition plate 18 and the right door plate 19. Each hanging ear 21 passes through its corresponding side door plate 17 and is matingly connected with a hook 22. Through the cooperation of the hook 22 and the hanging ear 21, the opening and locking of the side door plate 17 can be realized, which is convenient for operation.

[0039] Furthermore, there are two mold frame driving mechanisms, and the two mold frame driving mechanisms are symmetrically arranged front and rear. The two mold frame driving mechanisms act synchronously, so that the driving stability of the mold frame 12 is better.

[0040] Furthermore, the mold frame driving mechanism includes a sleeve 3 fixedly connected to the mounting plate 1, a rotating shaft 4 rotatably connected inside the sleeve 3, an upper swing rod 5 fixedly connected to the upper end of the rotating shaft 4, push-pull rods 9 are hinged at both ends of the upper swing rod 5 through pins, the other ends of the two push-pull rods 9 are hinged to their corresponding mold frames 12 through pins, and a lower end of the rotating shaft 4 is fixedly connected to a lower swing rod 2, and a driving rod 6 is hinged on the lower swing rod 2 through a pin. When pouring concrete, the push-pull rod 9 can provide stable support for the formwork 12, thereby supporting the two side walls of the inner mold core plate 11, preventing the upper end of the inner mold core plate 11 from being squeezed by concrete and elastically deformed, thereby preventing shrinkage during concrete pouring; when demolding, by pulling the driving rod 6, the lower swing rod 2 is driven to swing, thereby driving the upper swing rod 5 to swing through the rotating shaft 4, thereby pulling the two formworks 12 slightly inward through the two push-pull rods 9, thereby driving the two side walls of the inner mold core plate 11 to elastically deform and slightly deflect inward. Since there is a matching gap between the upper swing rod 5 and the push-pull rod 9 and between the push-pull rod 9 and the formwork 12, it will not interfere with the formwork 12 slightly deflecting with the inner mold core plate 11, so that the two side walls of the inner mold core plate 11 are separated from the two inner side walls of the RPC drainage ditch finished product 14, and then the RPC drainage ditch finished product 14 can be taken out.

[0041] Further, the base 15 is provided with two parallel linear guides 23, the left door panel 16 is provided with a first slide 27 slidably matched with the two linear guides 23, the inner mold core 35 is provided with a second slide 32 slidably matched with the two linear guides 23, the partition body 18 is provided with a third slide 33 slidably matched with the two linear guides 23, and the right door panel 19 is provided with a fourth slide 24 slidably matched with the two linear guides 23. The left door panel 16, the inner mold core 35, the partition body 18, and the right door panel 19 are slidably matched with the two linear guides 23. The relative sliding of the left door panel 16, the inner mold core 35, the partition body 18, and the right door panel 19 relative to the base 15 is achieved through the sliding cooperation between the first slide 27, the second slides 32, the third slides 33, and the fourth slide 24 and the two linear guides 23, respectively, with a simple structure and stable operation.

[0042] Further, a moving block 29 is fixedly connected to both the front and rear sides of the left door plate body 16, two moving blocks 29 are fixedly connected to both the front and rear sides of the inner mold core body 35, two moving blocks 29 are fixedly connected to both the front and rear sides of the partition plate body 18, and a moving block 29 is fixedly connected to both the front and rear sides of the right door plate body 19. The moving blocks 29 on each side are connected pairwise from left to right by a pull plate 28, and each pull plate 28 is provided with a strip-shaped sliding hole 30 corresponding to and adapted to the moving block 29; a driving block 31 is fixedly connected to both the front and rear sides of the partition plate body 18 and the right door plate body 19, and each driving rod 6 is hinged to the driving block 31 adjacent to its right side. When the mold is opened, by pulling the left door plate body 16 to the left, under the action of the strip-shaped sliding hole 30, the left door plate body 16 will move to the left by a distance of a strip-shaped sliding hole 30, so that the RPC drain gutter finished product 14 is separated from the outer mold 34 on its left side. Then, continue to pull the left door plate body 16 to the left, and the inner mold core body 35 on its right side can be driven to move left by the pull plate 28. Under the action of the strip-shaped sliding hole 30, the partition plate body 18 remains stationary. Therefore, the RPC drain gutter finished product 14 can be separated from the outer mold 34 on its right side. Since a relative displacement occurs between the inner mold core body 35 and the partition plate body 18, the driving rod 6 is pulled, thereby realizing the separation of the two side walls of the inner mold core plate 11 from the RPC drain gutter finished product 14. Then, continue to pull the left door plate body 16 to the left, and the partition plate body 18 on the right side can be driven to move left. By analogy, the separation between all the outer molds 34, the side walls of the inner mold core plate 11, and the bottom wall of the inner mold core plate 11 and the RPC drain gutter finished product 14 can be realized, and the operation is simple and convenient. In addition, the form of pulling the right door plate body 19 to the right, or the form of pulling the left door plate body 16 and the right door plate body 19 simultaneously can also be adopted, and the principle is the same.

[0043] It should be specifically noted that: in the description of the present invention, the orientation or positional relationship indicated by the terms "inner", "outer", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than requiring the present invention to be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.
