Description

Technical Field

[0001] The utility model relates to the technical field of plastic extrusion, in particular to an embedded core rod flow channel structure. Background Art

[0002] In modern industrial production, flow channel structures are widely used in various equipment and processes, such as chemical industry, food processing, plastic extrusion, and microelectronics heat dissipation. These flow channel structures usually require built-in mandrels to optimize fluid flow characteristics, improve heat transfer efficiency, or achieve specific process effects. However, the traditional embedded mandrel flow channel structure has many inconveniences in the removal and replacement of the mandrel, which seriously affects the production efficiency and the convenience of equipment maintenance.

[0003] The traditional embedded mandrel flow channel structure is often complex in design, with a tight connection between the mandrel and the flow channel. Special tools are required for disassembly, and the operation process is cumbersome and time-consuming. This not only increases the downtime in the production process, but also increases the cost and difficulty of equipment maintenance. In addition, since the mandrel is susceptible to wear or corrosion during long-term use, regular replacement of the mandrel becomes a key link to ensure the normal operation of the equipment, and the inconvenience of disassembly becomes a bottleneck restricting the efficient operation of this link.

[0004] Therefore, a kind of embedded mandrel flow channel structure is needed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and provide an embedded core rod flow channel structure.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an embedded core rod flow channel structure, comprising an outer mold body, the inner mold body is fixedly connected to the inner mold body, an inner cavity is opened inside the outer mold body, and a core rod and a quick release mechanism are arranged at the left end of the inner mold body.

[0007] Preferably, the quick-release mechanism comprises an installation cavity and a limiting column, the installation cavity is opened inside the inner mold body, and the limiting column is fixedly connected to the outer surface of the core rod.

[0008] Preferably, a sliding groove and a limiting groove are provided inside the installation cavity, the limiting column is slidably connected to the inner wall of the limiting groove, and the installation cavity is slidably connected to the outer surface of the core rod.

[0009] Preferably, a slide rod is fixedly connected to the inner wall of the slide groove, a slider is slidably connected to the outer surface of the slide rod, and the slider is slidably connected to the inner wall of the slide groove.

[0011] Preferably, a ball is rotatably connected inside the circular plate, and the outer surface of the ball is in contact with the core rod.

[0012] Beneficial effects:

[0013] Compared with the prior art, the embedded mandrel flow channel structure has the following beneficial effects:

[0014] 1. The utility model realizes the rapid installation and firm locking of the mandrel by setting up a quick-release mechanism. Specifically, after the mandrel is inserted and rotated to a specific position, the limit column can be accurately engaged in the predetermined position of the limit groove through the spring, thereby ensuring the stability and reliability of the mandrel and effectively preventing it from moving or falling off during operation. At the same time, with the help of the free rotation of the ball, the friction resistance of the mandrel during the installation and removal process is reduced, making the operation smoother and reducing equipment wear and operation difficulty.

DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] See also Figure 1 to Figure 4 An embedded core rod flow channel structure comprises an outer mold body 1, an inner mold body 2 is fixedly connected to the inner part of the outer mold body 1, an inner cavity 3 is opened inside the outer mold body 1, and a core rod 4 and a quick release mechanism 5 are arranged at the left end of the inner mold body 2.

[0023] The quick release mechanism 5 includes an installation cavity 501 and a limiting column 509. The installation cavity 501 is provided inside the inner mold body 2, and the limiting column 509 is fixedly connected to the outer surface of the core rod 4. A slide groove 502 and a limiting groove 503 are provided inside the installation cavity 501. The limiting column 509 is slidably connected to the inner wall of the limiting groove 503, and the installation cavity 501 is slidably connected to the outer surface of the core rod 4. A slide rod 508 is fixedly connected to the inner wall of the slide groove 502, and a slider 507 is slidably connected to the outer surface of the slide rod 508, and the slider 507 is slidably connected to the inner wall of the slide groove 502.

[0024] The inner wall of the installation cavity 501 is fixedly connected with a spring 504, the left end of the spring 504 is fixedly connected with a circular plate 505, the outer surface of the circular plate 505 is fixedly connected with a slider 507, the inner part of the circular plate 505 is rotatably connected with a ball 506, and the outer surface of the ball 506 contacts the core rod 4. There are two slide grooves 502, both of which are located inside the installation cavity 501. Each slide groove 502 is equipped with a slider 507 and a slide rod 508. Such a design ensures the stability and smoothness of the circular plate 505 during movement. There are four balls 506, all of which are embedded in the circular plate 505. The main function of these balls is to reduce the friction resistance between the core rod 4 and the circular plate 505 when the core rod 4 is locked, so that the insertion and rotation of the core rod 4 are easier. There are also two limiting grooves 503, and both are arranged inside the installation cavity 501. A limiting column 509 is arranged in each limiting groove 503. This structure ensures that the core rod 4 can be firmly locked in the installation cavity 501 to prevent it from moving or falling off during operation.

[0025] The quick release mechanism 5 is provided to realize the rapid installation and stable locking of the mandrel 4. After the mandrel 4 is inserted and rotated to a specific position, the limiting column 509 can be accurately engaged in the predetermined position of the limiting groove 503 through the spring 504, thereby ensuring the stability and reliability of the mandrel 4. It is effectively prevented from moving or falling off during operation. At the same time, with the free rotation of the ball 506, the friction resistance of the mandrel 4 during the installation and removal process is reduced, making the operation smoother, reducing equipment wear and operation difficulty.

[0026] The slide groove 502 , the slider 507 and the slide rod 508 can ensure that the circular plate 505 and the ball 506 can move smoothly inside the installation cavity 501 , thereby adapting to the position change of the core rod 4 during the installation and removal process.

[0027] Working principle: When the core rod 4 needs to be installed quickly, the operating steps are as follows: first, insert the core rod 4 into the installation cavity 501. During this process, the two limit posts 509 will slide along the corresponding limit groove 503. When the core rod 4 is inserted to the lowest position of the limit groove 503, the core rod 4 will contact the ball 506 and push the circular plate 505 and the spring 504 to move to the right through the ball 506. During this process, the spring 504 will shrink due to the pressure. By rotating the core rod 4 counterclockwise, the two limit posts 509 will also rotate in the limit groove 503. When it rotates to about ninety degrees, the core rod 4 is released. At this time, the spring 504 will use its elastic force to push the circular plate 505 and the ball 506 to move to the left, thereby pushing the core rod 4 into the limited position of the limit groove 503. During this process, the limit post 509 will be pushed into the limited position of the limit groove 503, thereby fixing the core rod 4. In this process, the ball 506 rotates freely between the core rod 4 and the circular plate 505. This design effectively reduces the friction resistance of the core rod 4 during rotation and limit fixation, making the insertion and extraction of the core rod 4 smoother. In addition, the combined design of the slide groove 502, the slider 507 and the slide rod 508 also plays a key role. This design ensures that the circular plate 505 and the ball 506 can move smoothly inside the installation cavity 501, thereby adapting to the position changes of the core rod 4 during installation and removal. When the core rod 4 needs to be removed, it is only necessary to press the core rod 4 downward to compress the spring 504, and then rotate the core rod 4 clockwise to make the limit column 509 rotate out of the locking position of the limit groove 503, so that the core rod 4 can be directly ejected from the installation cavity 501 by the elastic force of the spring 504. This design greatly simplifies the removal process of the core rod 4 and improves work efficiency. The utility model realizes the quick and convenient installation and removal of the core rod 4.
