Traditionally, boron diffusion furnace bodies are manufactured by firing. However, this method cannot be corrected in time during the manufacturing process, and the accuracy of the mold must be guaranteed. This can easily lead to large product deviations, affecting the accuracy of the processing.

[0004] Therefore, a boron diffusion heating furnace body forming mold is proposed to solve the problems mentioned above. Utility Model Content

The forming mold of the boron expansion heating furnace body, under the operation of the air extraction device, removes the air inside the mold body, so that a negative pressure space is formed on the surface of the mold body, and the material in the liquid storage cylinder is adsorbed on its surface until the material completely covers the guide rod and heating wire.

[0016] 2. The forming mold of the boron expansion heating furnace body can be controlled synchronously by controlling the operation of the drive device to control the height of the mold body in the liquid storage tank. The excess part is removed manually, and the mold body is moved back and forth in this way to ensure the uniformity of product forming.

[0017] 3. The boron expansion heating furnace body forming mold, by evenly setting multiple through holes, ensures the uniformity of gas flow, thereby ensuring the uniformity of the negative pressure space surface inside and outside the mold body, so that the material can be adsorbed in a uniform state, improving the quality of product forming.

[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. Example

[0026] Please see Figure 1 - Figure 5 In this embodiment, a boron expansion heating furnace body forming mold includes a mold body 1 and a connecting pipe 2 disposed at the lower end of the mold body 1. A guide rod 3 is disposed on the outside of the mold body 1, and there are several guide rods 3.

[0027] A heating wire 4 is sleeved on the outside of the guide rod 3;

[0028] A liquid storage cylinder 5 is provided below the main body of the mold 1;

[0029] In use, the upper end of the mold body 1 is connected to a drive device that controls its up and down movement, and the outer end of the connecting pipe 2 is connected to a vacuum device, so that the mold body 1 can move normally and vacuum its interior. Since the drive device and the vacuum device are well known technologies in the field, they are not described in detail in this embodiment.

[0030] When the device is in use, the mold body 1 and its outer parts move downwards simultaneously under the drive of the drive device and gradually immerse themselves in the liquid storage cylinder 5. While the mold body 1 moves, the air inside the mold body 1 is extracted by the operation of the air extraction device, so that a negative pressure space is formed on the surface of the mold body 1. The material in the liquid storage cylinder 5 is adsorbed on its surface until the material completely covers the guide rod 3 and the heating wire 4. After the material is formed and fixed on the outside of the mold body 1, the guide rod 3 and the heating wire 4 are positioned in the middle of the molded product. Finally, with the support of the specifications of the mold body 1 itself, accurate molding support is provided for the product.

[0031] By controlling the operation of the drive device, the height of the mold body 1 in the liquid storage cylinder 5 can be controlled synchronously, so that the mold body 1 can be moved out of the liquid storage cylinder 5. This allows the staff to observe the state of material adsorption on the surface of the mold body 1. Then, the excess part is removed manually, and the mold body 1 is immersed back into the liquid storage cylinder 5, so that the material gradually re-attaches to the surface of the gradually forming product. This process of moving the mold body 1 back and forth ensures the uniformity of product forming.

[0032] The interior of the mold body 1 is hollow, and the interior of the mold body 1 is connected to the interior of the connecting pipe 2;

[0033] A number of through holes 101 are provided through the outer surface of the mold body 1, and the through holes 101 are evenly distributed in a ring on the outer surface of the mold body 1.

[0034] Based on the flow support of the through hole 101, the mold body 1 is connected inside and out, and with the transmission of the connecting pipe 2, a stable negative pressure state can be formed inside it.

[0035] By uniformly arranging multiple through holes 101, the uniformity of gas flow is ensured, thereby ensuring the uniformity of the negative pressure space surface inside and outside the mold body 1, so that the material can be adsorbed in a uniform state, improving the quality of product molding, and isolating and filtering the material flowing into the mold body 1 and the connecting pipe 2 through the through holes 101, which can be further utilized. Since this part of the filtration structure is not an essential technical feature of this application, and this part of the structure is a technology known to those skilled in the art, it is not described in detail in this embodiment.

[0036] Both the upper and lower ends of the outer side of the mold body 1 are provided with rings for placing the guide rods 3, and the guide rods 3 are evenly distributed in a ring on the outer side of the mold body 1;

[0037] The heating wire 4 is located between the upper and lower rings, and the heating wire 4 is vertically threaded and sleeved on the outside of the guide rod 3;

[0038] The liquid storage cylinder 5 is hollow in the upper part. The liquid storage cylinder 5 is used to hold the slurry. The mold body 1 is inserted into the liquid storage cylinder 5.

[0039] In this process, the guide rod 3 is temporarily positioned on the outside of the mold body 1. After the product is formed on the outside of the mold body 1, it is removed as a whole along with the formed product.

[0040] Furthermore, by setting the liquid storage cylinder 5 to be unsealed at the top, it is convenient to put the raw materials cleaned off the outside of the mold body 1 into the liquid storage cylinder 5, and it is also convenient to directly observe the immersion status of the mold body 1 and the overall content of the slurry, thereby improving the convenience of the staff in performing the corresponding operations.

[0041] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0042] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing publicly available power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
