Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a core mold vibration pipe making machine. Background Technology

[0002] When manufacturing reinforced concrete drainage pipes using a core mold vibration pipe-making machine, a pre-fabricated steel reinforcement cage is precisely placed into the outer mold. Then, a core mold (inner mold) equipped with a high-frequency vibrator is inserted and positioned, forming the forming cavity of the pipe together with the outer mold. Next, concrete mixture is evenly poured into the mold cavity, and then the high-frequency vibration of the core mold is started to liquefy and fully compact it. After the vibration and compaction are completed, the core mold stops vibrating and is lifted out. The outer mold is then removed from the inner mold, and the newly formed pipe can be lifted off for steam or natural curing, thus completing the production of the reinforced concrete drainage pipe.

[0003] In the prior art, multiple sets of clamps are set at the bottom of the outer mold or the edge of the flange. Before the core mold vibrates, the multiple sets of clamps are adjusted to lock the outer mold on the rigid base to prevent the mold from moving and causing the tube to deform or have surface defects. After the tube is made, the clamps are released to release the restriction on the outer mold, and it is lifted vertically upward to remove the outer mold.

[0004] However, in actual use, the outer mold is cylindrical. In order to fix the outer mold and the base relatively during pipe making, multiple clamps need to be adjusted back and forth, which reduces the efficiency of pipe making for reinforced concrete drainage pipes. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology where the cylindrical outer mold is fixed on the base during the tube-making stage, requiring multiple clamps to be adjusted back and forth, which reduces the efficiency of tube making. Therefore, a core mold vibration tube-making machine is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a core mold vibration tube-making machine, including a base, an outer mold inserted into the base, a core mold fixedly connected inside the outer mold, a locking ring fixedly connected to the circumferential side of the outer mold, and a mold locking assembly. The mold locking assembly includes several extension platforms, which are fixedly connected to the base. Gears are rotatably connected inside the extension platforms. A limit rail is fixedly connected to the extension platforms, and a first rack is slidably connected inside the limit rail. The first rack meshes with the gear. A wedge block is fixedly connected to the side of the first rack. An electric telescopic rod is fixedly connected to the base. A ring frame is fixedly connected to the output end of the electric telescopic rod. Several second racks are fixedly connected to the bottom surface of the ring frame, and the second racks mesh with corresponding gears.

[0008] Preferably, an ear plate is fixedly connected to the side of the ring frame, and a slide rail is fixedly connected to the base, with the ear plate and the slide rail slidingly engaged.

[0009] Preferably, two symmetrical moving grooves are formed on the ear plate, a self-locking block is slidably connected in the moving groove, and a spring is fixedly connected between the self-locking block and the ear plate.

[0010] Preferably, two self-locking grooves are symmetrically formed inside the slide rail, and the shape of the groove opening is the same as the shape of the self-locking block.

[0011] Preferably, a pinch plate is fixedly connected to the surface of the self-locking block.

[0012] Preferably, the wedge block has an inclined surface on the side facing the locking ring.

[0013] Preferably, the ring frame and the outer mold are interlocked.

[0014] Preferably, the base has a plurality of fixing holes evenly distributed on it.

[0015] The present invention proposes a core mold vibration pipe-making machine, which has the following advantages: When in use, the electric telescopic rod extends and retracts, and multiple second racks move upward synchronously. After being driven by gears and first racks, multiple wedge blocks can be moved towards the locking ring position synchronously. This allows the outer mold to be quickly locked onto the base after it is inserted into the base, and the locking can be quickly released during demolding, thereby improving the efficiency of making reinforced concrete drainage pipes.

[0023] 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.

[0024] Example 1

[0025] Reference Figure 1-5 This utility model is a core mold vibration tube making machine, including a base 1, an outer mold 2 inserted and fitted on the base 1, a core mold 3 fixedly connected inside the outer mold 2, a locking ring 4 fixedly connected to the periphery of the outer mold 2, and a mold locking assembly, which includes several extension platforms 5, the extension platforms 5 being fixedly connected to the base 1, a gear 6 being rotatably connected inside the extension platform 5, a limit rail 19 being fixedly connected to the extension platform 5, a first rack 7 being slidably connected inside the limit rail 19, the first rack 7 meshing with the gear 6, a wedge block 8 being fixedly connected to the side of the first rack 7, an electric telescopic rod 11 being fixedly connected to the base 1, a ring frame 9 being fixedly connected to the output end of the electric telescopic rod 11, and several second racks 10 being fixedly connected to the bottom surface of the ring frame 9, the second racks 10 meshing with the corresponding gears 6.

[0026] The operation process in this embodiment is as follows: Figure 2 As shown, after the core mold 3 and the outer mold 2 are installed, the outer mold 2 is inserted into the base 1. At this time, the wedge block 8 is located outside the locking ring 4 and does not interfere with the overall up and down movement of the outer mold 2. After the outer mold 2 and the base 1 are fixed, a closed tubular cavity is formed between the outer mold 2 and the base 1, and a steel mesh is installed in the cavity.

[0027] The electric telescopic rod 11 extends and retracts upward, thereby causing each of the second racks 10 to move upward, such as... Figure 4As shown, the second rack 10 moves upward, causing the gear 6 to rotate clockwise. Due to the sliding fit between the first rack 7 and the limiting rail 19, and the meshing between the first rack 7 and the gear 6, as the electric telescopic rod 11 extends, each of the first racks 7 moves toward the axial position of the outer mold 2. The movement of the first rack 7 causes the wedge block 8 to move. The wedge block 8 corresponds to the locking ring 4. The movement of multiple wedge blocks 8 can lock the locking ring 4. Compared with the method of repeatedly adjusting the fixture to fix the outer mold 2 and the base 1, by using the wedge blocks 8 to move toward the locking ring 4, the inclined surfaces of multiple wedge blocks 8 can simultaneously clamp and fix the locking ring 4 around it, which can improve the working efficiency when making concrete pipes.

[0028] Example 2

[0029] The core mold 3 requires high-speed vibration during tube making, which can easily lead to loosening of the locking mechanism between the outer mold 2 and the base 1. Therefore, please refer to [the relevant documentation / reference needed]. Figure 2-5 Based on the first specific embodiment, the ring frame 9 is fixedly connected to the side of the ear plate 13, and the base 1 is fixedly connected to the slide rail 12. The ear plate 13 and the slide rail 12 are slidably engaged. Two moving grooves 14 are symmetrically opened on the ear plate 13. A self-locking block 16 is slidably connected in the moving groove 14. A spring 15 is fixedly connected between the self-locking block 16 and the ear plate 13. Two self-locking grooves 17 are symmetrically opened in the slide rail 12. The groove shape of the self-locking groove 17 is the same as the shape of the self-locking block 16. A pinch plate 18 is fixedly connected to the surface of the self-locking block 16. The wedge block 8 is inclined on the side facing the locking ring 4. The ring frame 9 and the outer mold 2 are inserted into each other. Several fixing holes 20 are evenly opened on the base 1.

[0030] The operation process of this embodiment is as follows: Multiple fixing rods are anchored into the bottom surface through fixing holes 20 to fix the base 1. The process of fixing the outer mold 2 to the base 1 is the process of the electric telescopic rod 11 extending and driving the ring frame 9 to move. The ring frame 9 is provided with ear plates 13 on the side. The slide rail 12 is fixedly connected to the surface of the base 1. That is, during the process of fixing the outer mold 2 to the base 1, the ear plates 13 always move upward along the slide rail 12. The spring 15 always pushes the self-locking block 16 to move toward the position of the slide rail 12. When the ring frame 9 moves to the fixed position, each wedge block 8 completes the fixing of the locking ring 4. At this time, the self-locking block 16 in the ring frame 9 is just parallel to the self-locking groove 17. At this time, the spring 15 pushes the self-locking block 16 to insert into its corresponding self-locking groove 17 to complete the limiting of the self-locking block 16. During the tube making stage, the position of the outer mold 2 is locked by two self-locking blocks 16, thereby avoiding the high-speed vibration of the core mold 3, which would cause the position between the outer mold 2 and the base 1 to loosen, and further improve the stability of the device.

[0031] After the pipe is made, pinch the two pinch plates 18 to compress the spring 15, so that the two self-locking blocks 16 are reset and the electric telescopic rod 11 is retracted, which can drive each wedge block 8 to reset, thereby quickly releasing the limit of the outer mold 2. The outer mold 2 can be lifted from the base 1 by using the suspension equipment to take out the finished reinforced concrete pipe.

[0032] 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.
