Description

Technical Field

[0001] This utility model relates to the technical field of heat flow guiding equipment, specifically a precision coaxial heat flow guiding device. Background Technology

[0002] A hot runner system typically consists of three main parts: a manifold, hot nozzles, and a temperature controller. In a tightly coaxial hot runner system, it is often necessary to install guiding devices such as guide pipes to guide the heat flow.

[0003] For example, the utility model "Hot Runner Guide Sleeve" (publication number: CN202702522U) uses a columnar part B located at the end of the annular placement part away from the columnar part A. This columnar part B has an axial guide hole C located at the front end of the columnar part B with a beveled surface. Compared to traditional nozzle guide sleeves, this utility model has lower pressure loss, better flowability, and is beneficial for product filling. However, in practice, because the device lacks an internal buffer structure, the impact force when the hot flow enters the device is large, which can easily damage the guide hole over time. Furthermore, the device is installed via a pin hole, which limits its installation position and makes it difficult to adjust. Therefore, this utility model provides a precision coaxial hot flow guide device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a precision coaxial heat flow guiding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision coaxial heat flow guiding device, comprising a heat flow guiding pipe and an installation chamber. One end of the top of the installation chamber is provided with an opening, and a sliding assembly is installed at the bottom inside the installation chamber. A sliding mounting plate is slidably mounted on the top of the sliding assembly. An adjusting screw is installed at the end of the top of the installation chamber away from the opening, and an adjusting screw is installed on the internal thread of the adjusting screw. The sliding mounting plate passes through the opening and extends to the outside of the installation chamber, and a connecting rod is installed at the end of the sliding mounting plate away from the adjusting screw. A heat flow guiding pipe is installed at the end of the connecting rod away from the sliding mounting plate.

[0006] Preferably, both ends of the heat flow guiding pipe are provided with mounting grooves, and a hinge shaft is installed inside each mounting groove. An arc-shaped guide plate is hinged to the outside of each hinge shaft, and a buffer spring is installed on the inside of each arc-shaped guide plate. The end of each buffer spring away from the arc-shaped guide plate is connected to the heat flow guiding pipe.

[0007] Preferably, a bearing is installed on the top of the sliding mounting plate at the end away from the connecting rod, and a connecting rod is installed inside the bearing. The end of the connecting rod away from the bearing is connected to the adjusting screw.

[0008] Preferably, a fixing base plate is installed at the end of the installation chamber away from the heat flow guiding pipe, and the fixing base plate is uniformly provided with mounting screw holes inside.

[0009] Preferably, the outer side of each buffer spring is provided with a corrosion-resistant layer.

[0010] Preferably, a handle is installed at the end of the adjusting screw away from the heat flow guiding pipe, and a sponge sleeve is installed on the outside of the handle.

[0011] Preferably, a set of reinforcing plates are symmetrically installed on the outer side of the connecting rod, and the end of the reinforcing plate away from the connecting rod is connected to the heat flow guiding pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This precision coaxial heat flow guiding device is equipped with a heat flow guiding pipe, a connecting rod, a sliding mounting plate, and a sliding assembly. In use, the fixed base plate can be fixed first, and the sliding mounting plate can slide on the sliding assembly. The heat flow guiding pipe can then be moved by the connecting rod. The installation position of the heat flow guiding pipe can be directly adjusted. The device has strong adjustability and wide applicability.

[0014] 2. This precision coaxial heat flow guiding device is equipped with bearings, connecting rods, adjusting screws, and adjusting tubes. In use, by rotating the adjusting screw, the adjusting screw moves inside the adjusting tube through the thread. The adjusting screw drives the sliding mounting plate to move together through the connecting rod and bearings, so the position of the heat flow guiding pipe can be directly adjusted. The adjustment process is relatively convenient and the device is relatively easy to use.

[0015] 3. This precision coaxial heat flow guiding device is equipped with a buffer spring, an arc-shaped guide plate, and a hinge shaft. After the heat flow enters the heat flow guiding pipe, it directly impacts the arc-shaped guide plate, which guides the flow. When the arc-shaped guide plate is subjected to impact force, it can rotate around the hinge position with the hinge shaft as the center, so that the arc-shaped guide plate squeezes the buffer spring. The buffer spring can buffer the impact force, which can reduce the impact force on the inside of the heat flow guiding pipe and help extend the service life of the heat flow guiding pipe.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides an embodiment of a precision coaxial heat flow guiding device, comprising a heat flow guiding pipe 1 and an installation chamber 2. One end of the top of the installation chamber 2 is provided with a through-hole 4, and a sliding assembly 12 is installed at the bottom inside the installation chamber 2. A sliding mounting plate 5 is slidably mounted on the top of the sliding assembly 12. An adjusting screw tube 9 is installed at the end of the top of the installation chamber 2 away from the through-hole 4, and an adjusting screw 8 is threaded inside the adjusting screw tube 9. The sliding mounting plate 5 passes through the through-hole 4 and extends to the outside of the installation chamber 2. A connecting rod 3 is installed at the end of the sliding mounting plate 5 away from the adjusting screw tube 9, and the connecting rod 3 is mounted at the end away from the sliding mounting plate 5. The device is equipped with a heat flow guiding pipe 1. A set of reinforcing plates are symmetrically installed on the outside of the connecting rod 3, and the ends of the reinforcing plates away from the connecting rod 3 are connected to the heat flow guiding pipe 1, which can make the connecting rod 3 and the heat flow guiding pipe 1 firmly installed. The end of the installation chamber 2 away from the heat flow guiding pipe 1 is equipped with a fixing base plate 11, and the interior of the fixing base plate 11 is evenly provided with mounting screw holes 10. The fixing base plate 11 can be fixed in a designated position through the mounting screw holes 10, so that the device can be firmly installed. The end of the adjusting screw 8 away from the heat flow guiding pipe 1 is equipped with a handle, and the outside of the handle is equipped with a sponge sleeve, which makes it easy for the operator to rotate the adjusting screw 8.

[0022] like Figure 1-3As shown, both ends of the heat flow guiding pipe 1 are provided with mounting grooves 15, and hinge shafts 16 are installed inside the mounting grooves 15. Arc-shaped guide plates 14 are hinged to the outer side of the hinge shafts 16, and buffer springs 13 are installed on the inner side of the arc-shaped guide plates 14. The end of the buffer spring 13 away from the arc-shaped guide plate 14 is connected to the heat flow guiding pipe 1. After the heat flow enters the heat flow guiding pipe 1, it directly impacts the arc-shaped guide plate 14 and can be guided by the arc-shaped guide plate 14. When the arc-shaped guide plate 14 is subjected to impact force, it can rotate around the hinge position with the hinge shaft 16 as the center, so that the arc-shaped guide plate 14 squeezes the buffer spring 13. The buffer spring 13 can buffer the impact force, which can reduce the impact force on the inside of the heat flow guiding pipe 1 and help extend the service life of the heat flow guiding pipe 1. The outer side of the buffer spring 13 is provided with a corrosion-resistant layer, which helps extend the service life of the buffer spring 13.

[0023] like Figure 1-2 As shown, a bearing 6 is installed on the top of the sliding mounting plate 5 at the end away from the connecting rod 3, and a connecting rotating rod 7 is installed inside the bearing 6. The end of the connecting rotating rod 7 away from the bearing 6 is connected to the adjusting screw 8. In use, by rotating the adjusting screw 8, the adjusting screw 8 moves inside the adjusting screw tube 9 through the thread. The adjusting screw 8 drives the sliding mounting plate 5 to move together through the connecting rotating rod 7 and the bearing 6, so that the position of the heat flow guiding pipe 1 can be directly adjusted. The adjustment process is relatively convenient and the device is relatively easy to use.

[0024] Working principle:

[0025] During installation, first fix the mounting base plate 11 to the designated position through the mounting screw hole 10. Then, the operator can rotate the adjusting screw 8 clockwise or counterclockwise. The adjusting screw 8 drives the connecting rotating rod 7 to rotate. The connecting rotating rod 7 rotates inside the bearing 6. The connecting rotating rod 7 will not drive the sliding mounting plate 5 to rotate through the bearing 6.

[0026] Furthermore, the adjusting screw 8 moves inside the adjusting screw tube 9 via a thread, and the adjusting screw 8 drives the connecting rotating rod 7 to move together, so that the connecting rotating rod 7 drives the sliding mounting plate 5 to move via the bearing 6, and the sliding mounting plate 5 drives the heat flow guiding pipe 1 to move via the connecting rod 3, so that the heat flow guiding pipe 1 can be adjusted to a specified position and the heat flow can be guided through the heat flow guiding pipe 1.

[0027] After the hot flow enters the hot flow guiding pipe 1, it directly impacts the arc-shaped guide plate 14. The flow can be guided by the arc-shaped guide plate 14. When the arc-shaped guide plate 14 is subjected to impact force, it can rotate around the hinge position with the hinge shaft 16 as the center, so that the arc-shaped guide plate 14 squeezes the buffer spring 13. The buffer spring 13 can buffer the impact force, which can reduce the impact force on the inside of the hot flow guiding pipe 1 and help extend the service life of the hot flow guiding pipe 1.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
