Description

Technical Field

[0001] This utility model relates to the field of workpiece preheating technology, specifically a heat pipe rapid preheating mold. Background Technology

[0002] Preheating of heat pipes is a critical operation to eliminate potential defects, activate the working medium, and ensure stable heat transfer performance. Its requirements are mainly concentrated in manufacturing processes, first use, special environmental applications, and maintenance and testing.

[0003] Traditional preheating of heat pipes involves using a preheating pan, where the heat pipes are laid flat. However, the complex structure of the heat pipes results in a small effective surface area on the pan, leading to a limited number of heat pipes and faster heat loss, increasing energy consumption. Furthermore, uneven heating of the heat pipes affects preheating quality. To improve preheating efficiency, preheating molds are used. These molds are designed to fit the shape of the heat pipes, ensuring a close fit and improving efficiency while reducing heat loss. However, traditional preheating molds are designed based on the heat pipe dimensions, resulting in fixed sizes that cannot accommodate different heat pipe sizes. This necessitates the production of different sized molds for different heat pipes, increasing costs. Utility Model Content

Detailed Implementation

[0025] 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.

[0026] This utility model provides, for example Figures 1-6 The heat pipe rapid preheating mold shown includes:

[0027] Mold body 1;

[0028] The mold body 1 includes a first heating box 101 and a second heating box 102. Two sets of heating tubes 2 are fixed inside the first heating box 101 and the second heating box 102. An adjustment component 3 for adjusting the width of the mold body 1 is provided between the first heating box 101 and the second heating box 102.

[0029] The top of the mold body 1 is provided with a top cover 4 that fits into the heat pipe;

[0030] The total width of the first heating box 101 and the second heating box 102 is adjusted by adjusting component 3, so that the heat pipe can be easily attached to the outside of the mold body 1. At the same time, a top cover 4 is installed on the top of the mold body 1. The top cover 4 is designed according to the structure of the heat pipe, so that the top cover 4 can fit with the bent section of the heat pipe, ensuring the uniformity of heat pipe preheating and reducing the production cost of preheating mold.

[0031] Among them, such as Figure 2-3 As shown:

[0032] The adjustment assembly 3 includes a threaded cylinder 31 fixed on the side wall of the inner cavity of the second heating box 102, and a threaded rod 32 rotatably connected to the side wall of the first heating box 101 via a bearing. One end of the threaded rod 32 passes through the inner cavity of the second heating box 102 and is threaded through the inner cavity of the threaded cylinder 31. An operating hole 33 is provided at the end of the threaded rod 32 away from the threaded cylinder 31. By rotating the threaded rod 32 on the first heating box 101 to cooperate with the threaded cylinder 31 on the second heating box 102, the distance between the first heating box 101 and the second heating box 102 is adjusted, thereby adjusting the width of the mold body 1 to accommodate heat pipe preheating treatment of different sizes.

[0033] Furthermore, such as Figure 3 and Figure 5-6 As shown:

[0034] The first heating box 101 is sleeved on one end of the second heating box 102. The inner cavity of the first heating box 101 is provided with a limiting groove 5. The outer side of the second heating box 102 is fixed with a limiting strip 6 that is aligned with the limiting groove 5. The limiting strip 6 is slidably disposed in the limiting groove 5. By sliding the limiting strip 6 in the limiting groove 5, the first heating box 101 is ensured to slide stably on the outer side of one end of the second heating box 102, preventing the first heating box 101 and the second heating box 102 from generating heat, which would cause the heat inside the mold body 1 to leak outward, resulting in a reduction in the efficiency of the heat pipe preheating.

[0035] Preferred, such as Figure 3 and Figure 5-6 As shown:

[0036] A positioning cylinder 7 is fixed on the side wall of the inner cavity of the second heating box 102, and a positioning column 8 is fixed on the side wall of the inner cavity of the first heating box 101. One end of the positioning column 8 slides through the inner cavity of the positioning cylinder 7. Through the cooperation of the positioning column 8 and the positioning cylinder 7, the first heating box 101 and the second heating box 102 are ensured to move smoothly under the traction of the threaded rod 32 and the threaded cylinder 31, so as to avoid the two ends tilting and causing jamming and adjustment obstruction.

[0037] It is worth noting that, such as Figure 4 As shown:

[0038] Two sets of support plates 9 are fixed in the inner cavity of the top cover 4. The bottom of the support plates 9 is flush with the bottom of the top cover 4. The support plates 9 enhance the stability of the top cover 4 structure and prevent multiple heat pipes from being fitted onto the top cover 4, causing it to deform and collapse, thus affecting the fit between the heat pipes and the top cover 4.

[0039] In a further preferred embodiment, such as Figure 2 and Figure 4 As shown:

[0040] The top of the top cover 4 has a countersunk hole, and a mounting bolt 10 is installed in the countersunk hole. The mounting bolt 10 passes through the support plate 9 and is threaded to the top of the first heating box 101. The mounting bolt 10 facilitates the connection between the top cover 4 and the first heating box 101, and connects the top cover 4 and the mold body 1 into one piece. The top cover 4 evenly distributes heat to the heat pipe, making the heat pipe preheating more uniform.

[0041] In addition, such as Figure 2-3 and Figure 5 As shown:

[0042] A limiting seat 11 is fixed at the bottom of the second heating box 102 on the side away from the first heating box 101. The inner cavity of the limiting seat 11 is set at an angle on the side away from the second heating box 102. The limiting seat 11 is set to limit the heat pipe and ensure that the heat pipe fits neatly on the mold body 1. At the same time, the angled side of the inner cavity of the limiting seat 11 facilitates the insertion of the heat pipe and has a guiding effect.

[0043] In practical use, select the appropriate top cover 4 according to the size of the heat pipe, and then fix the top cover 4 to the top of the first heating box 101 with the mounting bolts 10. Then, insert a tool into the operating hole 33 to rotate the threaded rod 32. The threaded rod 32 rotates inside the threaded cylinder 31, which facilitates the adjustment of the distance between the first heating box 101 and the second heating box 102. The side of the second heating box 102 away from the first heating box 101 should be flush with the top cover 4. Then, insert the heating rod into the heating rod insert tube, and the heating rod will diffuse heat into the mold body 1. The air inside the mold is heated, and then the temperatures of the first heating chamber 101 and the second heating chamber 102 are raised at a uniform rate. Then, the first heating chamber 101 and the second heating chamber 102 transfer the heat to the top cover 4 through heat conduction. The heat pipes that need to be preheated are clamped from the top of the top cover 4 onto the outside of the mold body 1. Since the mold body 1 is adjusted according to the size of the top cover 4, the top cover 4 fits against the outside of the mold body 1 and the heat pipes, so that the heat pipes are heated evenly. Since the heat pipes are neatly arranged on the outside of the mold body 1, heat loss can be reduced and the preheating efficiency can be improved.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
