Description

Technical Field

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

[0002] The core mold vibration pipe-making machine is a common pipe-making equipment. Its principle is as follows: inner and outer molds are vertically set on a main worktable located in a pit. Concrete is poured between the inner and outer molds through a circular material distribution device. A high-frequency vibrator installed in the inner mold transmits the excitation force through a tensioning connecting ring, which is then transmitted from the inner mold to the concrete material in the pipe mold. The concrete material, subjected to high-frequency vibration, gradually compacts. In production using the core mold vibration pipe-making machine, the outer mold must first be hoisted and positioned on the bottom mold. Then, the combined outer and bottom mold is hoisted onto the main worktable. During the hoisting and positioning process, auxiliary personnel are needed near the bottom mold to direct and guide the hoisting operators in moving the outer mold with the crane, ensuring alignment between the outer and bottom molds. This process is quite cumbersome, requiring manual alignment based on visual positioning, which is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this invention is to provide a core mold vibration tube making machine, which simplifies the positioning of the outer mold and the bottom mold and improves the bonding efficiency of the outer mold and the bottom mold.

[0004] To solve the above-mentioned technical problems, the embodiments of this utility model provide a technical solution as follows:

[0005] A core mold vibration tube-making machine includes a bottom mold and an inner mold vertically disposed at the center of the bottom mold. An outer mold is coaxially sleeved on the inner mold, and a forming cavity is formed between the outer mold and the inner mold. A pressing mold is provided at one end of the forming cavity away from the bottom mold. A power shaft is rotatably connected to one end of the pressing mold, and the other end is accommodated at the end of the forming cavity. A first guide post is provided on the bottom mold facing the outer mold, and a first guide sleeve is provided on the outer mold that slides with the first guide post. The end of the outer mold with the first guide sleeve is vertically connected and fixed to the bottom mold.

[0006] Furthermore, a positioning mold is sleeved on the power shaft, the positioning mold has a second guide post facing the outer mold, and the outer mold has a second guide sleeve that slides with the second guide post.

[0007] Furthermore, there are at least two first guide pillars, which are evenly distributed on the same circumference with the central axis of the bottom mold as the rotation axis, and the second guide pillar is arranged correspondingly to the first guide pillar.

[0008] Furthermore, the rolling die includes a cylindrical body and a connecting arm fixedly mounted on the cylindrical body. The connecting arm is rotatably connected to the power shaft, and one end of the cylindrical body is engaged with one end of the forming cavity along its axial direction.

[0009] Furthermore, the mold is connected to a power device, which can drive the mold to rotate around a power shaft.

[0010] Furthermore, the positioning mold includes a positioning body and a support rod fixedly mounted on the positioning body. The support rod is rotatably connected to the power shaft, and the second guide post extends perpendicularly to the positioning body toward the outer mold.

[0011] Furthermore, the positioning body is an annular cylindrical structure.

[0012] Furthermore, the power shaft is connected to a motor, and the power shaft can move up and down vertically in the direction of the bottom mold under the drive of the motor.

[0013] Compared with the prior art, this utility model's embodiment utilizes a sliding fit between the first guide post of the bottom mold and the first guide sleeve of the outer mold. This allows the outer mold to be hoisted and fixed on the bottom mold, enabling rapid positioning through the guiding fit of the first guide post and the first guide sleeve. This reduces the positioning difficulty for auxiliary personnel and improves the efficiency of the connection between the outer mold and the bottom mold. The sliding fit between the first guide post and the first guide sleeve also reduces the probability of misalignment between the outer mold and the bottom mold, improving the safety of the operators. Furthermore, the positioning mold and the second guide post ensure that the upper end of the outer mold is fixed by the positioning mold, while the lower end is connected and fixed by the bottom mold and the first guide post. This increases the consistency between the positioning mold, the outer mold, and the bottom mold, effectively reducing the deformation amplitude of the outer mold caused by vibration. This contributes to the consistency of the finished pipe shape and increases the uniformity of the wall thickness of the finished pipe. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0020] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0021] like Figure 1-3As shown, in one embodiment of this utility model, a core mold vibration pipe-making machine includes a bottom mold 7, which has a through-hole central connecting hole 71 for accommodating an inner mold 5. One end of the inner mold 5 passes through the connecting hole 71 and is perpendicular to the bottom mold 7. The inner mold 5 has a built-in vibration device (not shown in the figure). An outer mold 3 is coaxially sleeved on the inner mold 5. One end of the outer mold 3 is detachably fixedly connected to the bottom mold 7. A forming cavity 6 is formed between the outer mold 3 and the inner mold 5. The forming cavity 6 is used to fill the pipe-making material, which includes, but is not limited to, concrete, cement mixture, etc. A compaction mold 4 is provided at the end of the forming cavity 6 away from the bottom mold 7. One end of the compaction mold 4 is rotatably connected to a power shaft 1, and the other end is housed in the end of the forming cavity 6. The power shaft 1 is connected to a motor, which drives the power shaft 1 to move up and down in a direction perpendicular to the bottom mold 7. This movement of the power shaft 1 causes the compaction mold 4 to either disengage from or engage with one end of the forming cavity 6, used for compacting the tube-making material and shaping the tube opening within the forming cavity 6. The bottom mold 7 has a first guide post 72 facing the outer mold 3. The outer mold 3 has a first guide sleeve 31 that slides with the first guide post 72. When the outer mold 3 is hoisted and connected to the base, the guide post and guide sleeve engage, causing the end of the outer mold 3 with the first guide sleeve 31 to be perpendicularly connected and fixed to the bottom mold 7. Preferably, at least two first guide posts 72 are provided, evenly distributed on the same circumference with the central axis of the bottom mold 7 as the axis of rotation. By slidingly engaging the first guide post 72 of the bottom mold 7 with the first guide sleeve 31 of the outer mold 3, the outer mold 3 is hoisted and fixed on the bottom mold 7. The first guide post 72 and the first guide sleeve 31 can quickly position the outer mold, reducing the positioning difficulty for auxiliary personnel and improving the efficiency of the combination of the outer mold 3 and the bottom mold 7. At the same time, the sliding engagement of the first guide post 72 and the first guide sleeve 31 reduces the probability of misalignment between the outer mold 3 and the bottom mold 7, thus improving the safety of the workers.

[0022] In one embodiment, the rolling die 4 includes a cylindrical body 41 and a connecting arm 42 fixedly disposed on the cylindrical body 41. One end of the cylindrical body 41 is engaged with one end of the forming cavity 6 in the axial direction. The connecting arm 42 is rotatably connected to the power shaft 1. Preferably, a power device (not shown in the figure) is connected to the rolling die 4. The power device can drive the rolling die 4 to rotate around the power shaft 1. Under the action of the power shaft 1 and the power device, the rolling die 4 can realize the rotational extrusion of the tube-making material in the forming cavity 6, and can further compact the tube-making material.

[0023] In one embodiment, the core mold vibration tube-making machine provided by this utility model further includes a positioning mold 2. The positioning mold 2 includes a positioning body 22 and a support rod 21 fixedly mounted on the positioning body 22. The center of the support rod 21 is rotatably connected to the power shaft 1. The positioning mold 2 can move up and down relative to the outer mold 3 following the power shaft 1. A second guide post 23 is provided vertically at one end of the positioning body 22 facing the outer mold 3. A second guide sleeve 32 is provided corresponding to the second guide post 23 on the outer mold 3. When the positioning mold 2 and the end of the outer mold 3 are combined, the second guide post 23 and the second guide sleeve 32 slide together to provide guidance, so that the positioning mold 2 and the outer mold 3 can be quickly combined. Preferably, there are at least two second guide posts 23, which are evenly distributed on the same circumference parallel to the plane of the outer mold 3 port. Preferably, the positioning body 22 is an annular cylindrical structure. Through the cooperation of the second guide post 23 and the second guide sleeve 32, the support of the outer mold 3 port is effectively increased, and the deformation of the outer mold 3 during the vibration tube-making process is reduced.

[0024] In one embodiment, the first guide post 72 and the second guide post 23 are correspondingly arranged. The outer mold 3 and the bottom mold 7 are fixed by the cooperation of the first guide post 72 and the first guide sleeve 31. The positioning mold 2 and the outer mold are connected by the cooperation of the second guide post 23 and the second guide sleeve 32. This can increase the consistency of the connection between the positioning mold 2, the outer mold 3 and the bottom mold 7, effectively reduce the deformation amplitude of the outer mold 3 caused by vibration, and is conducive to the consistency of the shape of the finished pipe and the uniformity of the wall thickness of the finished pipe.

[0025] Compared with the prior art, this utility model's embodiment utilizes a sliding fit between the first guide post of the bottom mold and the first guide sleeve of the outer mold. This allows the outer mold to be hoisted and fixed on the bottom mold, enabling rapid positioning through the guiding fit of the first guide post and the first guide sleeve. This reduces the positioning difficulty for auxiliary personnel and improves the efficiency of the connection between the outer mold and the bottom mold. The sliding fit between the first guide post and the first guide sleeve also reduces the probability of misalignment between the outer mold and the bottom mold, improving the safety of the operators. Furthermore, the positioning mold and the second guide post ensure that the upper end of the outer mold is fixed by the positioning mold, while the lower end is connected and fixed by the bottom mold and the first guide post. This increases the consistency of the connections between the positioning mold, the outer mold, and the bottom mold, effectively reducing the deformation amplitude of the outer mold caused by vibration. This contributes to the consistency of the finished pipe shape and increases the uniformity of the wall thickness of the finished pipe.

[0026] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
