Abstract
Description
Technical Field
[0001] This utility model relates to the field of extrusion equipment technology, specifically to an irregularly shaped multi-cavity tube extrusion equipment. Background Technology
[0002] In the field of traditional mold manufacturing, existing technologies generally suffer from poor flexibility and insufficient adjustment precision, making it difficult to quickly adjust the shape and size of the extrusion cross-section, resulting in low production efficiency and increased production costs. Furthermore, traditional molds typically employ a fixed structure and lack modular adjustment mechanisms, making the assembly process complex, compromising positioning accuracy and sealing performance, and consequently increasing maintenance costs.
[0003] As modern industry develops towards a multi-variety, small-batch production model, the inadequacy of traditional molds has become increasingly apparent. The adjustment process is typically time-consuming, affecting not only product consistency and molding quality but also failing to meet the demands of efficient, precise, and flexible production.
[0004] In view of the above, in order to overcome the above technical problems, this utility model designs an irregularly shaped multi-cavity tube extrusion device, which solves the above technical problems. Utility Model Content
[0005] The technical objective of this invention is to provide a multi-cavity tube extrusion device that can quickly adapt to the production of tubes with different cross-sections by changing the shape of the tubes and adjusting the number and position of the adjusting tubes, thus meeting diverse needs. It does not require changing the overall die head. Furthermore, rotating the adjusting disc drives the slider to move radially, achieving precise position adjustment of the adjusting tubes. This allows for real-time optimization of the extrusion cross-sectional shape and reduces downtime for debugging.
[0006] To achieve the above-mentioned technical objectives, this utility model provides the following technical solution: This utility model provides an irregularly shaped multi-cavity tube extrusion device, including a transmission box, a base, a barrel, a feeding port, and a controller, as well as an extrusion die. One end of the output shaft of the transmission box is connected to the barrel. The base is fixedly installed below the barrel, and the feeding port is installed on the barrel. The controller is installed on the side of the barrel, and the extrusion die is fixedly installed on the left end of the barrel. The extrusion die is provided with a rotatable adjustment disc. When the adjustment disc is rotated, the adjustment disc drives the slider to move outward under the action of the arc groove, thereby moving the adjustment cylinder to the outer periphery. Thus, the position of the adjustment cylinder within the outer shell is adjusted by the movement of the adjustment cylinder.
[0007] Preferably, the extrusion die head includes an adjusting plate, a limiting plate, and a housing. The adjusting plate is installed at one end of the extruded material barrel. The side of the adjusting plate away from the material barrel has an array of sliding grooves. A slider is slidably installed inside the sliding grooves. The slider has an L-shaped cross-section. The limiting plate is installed on the side of the adjusting plate with the sliding grooves. The housing is fixedly installed on the other side of the limiting plate. The housing has an array of sliding grooves inside, and the positions of the sliding grooves are parallel to each other.
[0008] Preferably, a fixed cylinder is installed at the coaxial center of the limiting plate. The fixed cylinder is bullet-shaped and a compression spring is snapped into the inside of the fixed cylinder. A baffle is snapped into the other end of the compression spring. A shaped cylinder is threaded into the inside of the fixed cylinder. A connecting rod is fixedly installed in an array around the fixed cylinder. The other end of the connecting rod is fixedly connected to the inside of the limiting plate, and the two sides of the connecting rod are tapered.
[0009] Preferably, the limiting disk has an array of arc-shaped grooves, the number of which is the same as the number of sliding grooves, and one outer end of the slider is located inside the arc-shaped groove.
[0010] Preferably, a buffer spring is snapped into the inside of one end of the slider located in the arc groove, a sealing plate is installed at the other end of the buffer spring, and an adjusting cylinder is threaded onto the slider.
[0011] The beneficial effects of this utility model are as follows: 1. By changing the shape of the irregularly shaped cylinders and adjusting the number and position of the adjusting cylinders, it is possible to quickly adapt to the production of pipes with different cross-sections, meeting diverse needs without replacing the entire die head. Furthermore, rotating the adjusting disc drives the slider to move radially, achieving precise position adjustment of the adjusting cylinders, which can optimize the extrusion cross-sectional shape in real time and reduce downtime for debugging.
[0012] 2. The fixed cylinder is designed with a compression spring and baffle structure. By applying pressure to the irregular cylinder, the friction of the inner wall of the fixed cylinder is increased, thereby enhancing the stability of the irregular cylinder. When the irregular cylinder is not installed, the baffle can prevent material from flowing into the fixed cylinder.
[0013] 3. By rotating the adjustment disc to drive the L-shaped slider to move within the sliding groove, the adjustment cylinder is moved radially, enabling rapid and precise adjustment of the cross-sectional dimensions and shape of irregularly shaped pipes without the need to replace the overall mold head; and the parallel alignment design of the limit disc and the outer shell sliding groove ensures that the adjustment cylinder can move along the specified position, avoiding the adjustment cylinder from tilting.

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0018] like Figure 1 , 2As shown in Figures 3, 4, 5, and 6, this utility model provides an irregularly shaped multi-cavity tube extrusion device, including a transmission box 1, a base 2, a barrel 3, a feeding port 4, and a controller 5, as well as an extrusion die 6. The base 2 is installed at one end of the output shaft of the transmission box 1, and the barrel 3 is fixedly installed on the top of the base 2 and connected to one end of the output shaft of the transmission box 1. The feeding port 4 is installed on the barrel 3, and the controller 5 is installed on the side of the barrel 3. The extrusion die 6 is fixedly installed at the left end of the barrel 3. The extrusion die 6 is provided with a rotatable adjusting disc 61 inside. When the adjusting disc is rotated, the adjusting disc 61 drives the slider 612 to move outward under the action of the arc groove 621, thereby causing the adjusting cylinder 6123 to move outward, thereby adjusting its position inside the outer shell 63 by the movement of the adjusting cylinder 6123.
[0019] By replacing the irregularly shaped cylinders 6133 with different shapes and adjusting the number and position of the adjusting cylinders 6123, it is possible to quickly adapt to the production of pipes with different cross-sections, meeting diverse needs without replacing the entire die head. Furthermore, rotating the adjusting disc 61 drives the slider 612 to move radially, achieving precise position adjustment of the adjusting cylinders 6123, which can optimize the extrusion cross-sectional shape in real time and reduce downtime for debugging.
[0020] When installing the shaped cylinder 6133, first align the selected shaped cylinder 6133 with the extrusion baffle 6132, and then connect it to the fixed cylinder 613 via threads. When installing the adjusting cylinder 6123, determine the number and position of the adjusting cylinders 6123 according to requirements, and install them into the slider 612. During installation, the sealing plate 6122 must be pushed first, and then the threaded connection must be made. After the installation of the adjusting cylinder 6123 and the shaped cylinder 6133 is completed, rotate the adjusting disc 61. Under the action of the arc groove 621, the adjusting disc 61 drives the slider 612 to move outward, thereby moving the adjusting cylinder 6123 to the periphery, achieving the final adjustment of the model.
[0021] like Figure 1 , 2 As shown in Figure 3, the extrusion die 6 includes an adjusting plate 61, a limiting plate 62, and a housing 63. The adjusting plate 61 is installed at one end of the extrusion of the barrel 3. The adjusting plate 61 has an array of sliding grooves 611 on the side away from the barrel 3. A slider 612 is slidably installed inside the sliding grooves 611. The slider 612 has an L-shaped cross-section. The limiting plate 62 is installed on the side of the adjusting plate 61 with the sliding grooves 611. The housing 63 is fixedly installed on the other side of the limiting plate 62. The housing 63 has an array of sliding grooves 631 inside, and the positions of the sliding grooves 631 and the sliding grooves 611 are parallel to each other.
[0022] The L-shaped slider 612 is driven to move within the sliding groove 61 by rotating the adjustment disc 61, which in turn drives the adjustment cylinder 6123 to move radially, thus enabling rapid and precise adjustment of the cross-sectional size and shape of the irregular-shaped pipe without the need to replace the overall mold head. The parallel alignment design of the limit disc 62 and the sliding groove 631 of the outer shell 63 ensures that the adjustment cylinder 6123 can move along the specified position, avoiding the skewness of the adjustment cylinder 6123.
[0023] like Figure 3 , 4 As shown in Figures 5 and 6, a fixed cylinder 613 is installed at the coaxial center of the limiting disk 62. The fixed cylinder 613 is bullet-shaped, and a compression spring 6131 is snapped into the inside of the fixed cylinder 613. A baffle 6132 is snapped into the other end of the compression spring 6131. A non-circular cylinder 6133 is threaded into the inside of the fixed cylinder 613. A connecting rod 614 is fixedly installed in an array around the fixed cylinder 613. The other end of the connecting rod 614 is fixedly connected to the inside of the limiting disk 62, and the two sides of the connecting rod 614 are tapered.
[0024] The bullet-shaped fixed cylinder 613 effectively buffers melt pressure fluctuations, ensuring uniform and stable material flow. The fixed cylinder 613 incorporates a compression spring 6131 and a baffle 6132, applying pressure to the shaped cylinder 6133 to increase friction on its inner wall, thus enhancing its stability. When the shaped cylinder 6133 is not installed, the baffle 6132 prevents material from flowing into it. The fixed cylinder 613 and the shaped cylinder 6133 are connected by threads, and with the rigid support of the tapered connecting rod 614, quick assembly and disassembly are possible while ensuring precise alignment, significantly improving the efficiency of switching between multiple product specifications. The tapered design at both ends of the connecting rod 614 further ensures the uniformity and stability of material flow.
[0025] like Figure 3 and 4 As shown, the limiting disk 62 has an array of arc-shaped grooves 621. The number of arc-shaped grooves 621 is the same as the number of sliding grooves 611, and one outer end of the slider 612 is located in the arc-shaped groove 621.
[0026] The structure of one end of the slider 612 being embedded in the arc groove 621 ensures that all sliders 612 move radially synchronously when the adjustment disk 61 is rotated, avoiding misalignment and achieving uniform deformation of the irregular cross section.
[0027] like Figure 3 , 4 As shown in Figures 5 and 6, a buffer spring 6121 is snapped into the inside of one end of the arc groove 621 of the slider 612, and a sealing plate 6122 is installed on the other end of the buffer spring 6121. An adjusting cylinder 6123 is threaded onto the slider 612.
[0028] The design of the internal buffer spring 6121 and sealing plate 6122 effectively compresses the regulating cylinder 6123, increasing its friction inside the slider 612, thereby improving stability. At the same time, the sealing plate 6122 also prevents material from entering the slider 612 during flow.
[0029] In operation, the operator first adjusts the extrusion die 6. By selecting irregularly shaped cylinders 6133 of different sizes and shapes, and adjusting the size, shape, and number of adjusting cylinders 6123, the required extrusion mold can be designed. Furthermore, by rotating the adjusting disc 61, the position of the adjusting cylinders 6123 inside the outer casing 63 can be changed, thereby further adjusting the shape of the mold.
[0030] When installing the shaped cylinder 6133, first align the selected shaped cylinder 6133 with the extrusion baffle 6132, and then connect it to the fixed cylinder 613 via threads. When installing the adjusting cylinder 6123, determine the number and position of the adjusting cylinder 6123 according to the requirements, and install it into the slider 612; during the installation process, the sealing plate 6122 must be pushed first, and then the threaded connection must be made.
[0031] After the installation of the adjusting cylinder 6123 and the irregular cylinder 6133 is completed, the adjusting disk 61 is rotated. Under the action of the arc groove 621, the adjusting disk 61 drives the slider 612 to move outward, thereby moving the adjusting cylinder 6123 to the outside, and realizing the final adjustment of the model.
[0032] The above description is merely illustrative of this disclosure, and modifications may be made to the present invention in light of the above detailed description. The terminology used in the appended claims should not be construed as limiting the present invention to the specific embodiments disclosed in the specification. Rather, the scope of the present invention will be fully defined by the appended claims, which will be interpreted according to established principles of claim interpretation.
