Description

Technical Field

[0001] This utility model belongs to the field of precision parts manufacturing technology, specifically relating to a shell drying chamber. Background Technology

[0002] When manufacturing precision parts, a wax film is injected into a mold. Then, according to the shape and specifications of the wax film, a layer of material is covered on the surface of the wax film. After that, the wax film wrapped by the material is melted by high temperature. The material separated at this time is called the shell, which serves as the template and foundation for the subsequent manufacturing of precision parts. In the current shell manufacturing process, the shell needs to be placed in a specific drying room. By controlling the temperature and humidity in the room, the quality of the shell itself is improved, which is a key step in the current shell manufacturing process.

[0003] In practical use, existing drying chambers typically move mold shells into the chamber in batches. The heating system of the drying chamber mainly consists of a hot air blower or a blower. The hot air blows heated air into the drying chamber. However, in actual use, existing drying chambers cannot process dust, particulate matter, or other impurities in the air being drawn in. As a result, these impurities flow into the drying chamber along with the air. With the accumulation of impurities, the humidity of the air in the drying chamber cannot be precisely controlled because the impurities absorb moisture. Consequently, the mold shells in the drying chamber may crack or break during the drying process, affecting the overall work quality.

[0004] Therefore, this utility model proposes a shell drying chamber that filters impurities in the input air before processing it, allowing the air to dry the shell at a predetermined temperature and humidity. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0007] A shell drying chamber includes an air heating component, which mainly consists of a constant temperature unit body, a negative pressure pump body, an air intake pipe, and an air inlet pipe. The negative pressure pump body is installed on the side of the constant temperature unit body. An air intake pipe is installed at the air intake end of the negative pressure pump body, and an air inlet pipe is installed at the air outlet end of the negative pressure pump body. The air inlet pipe is connected to the constant temperature unit body, and a filter component is installed on the air intake pipe to filter impurities in the intake air.

[0008] As a preferred technical solution of this utility model, the filter assembly includes a filter chamber and a filter screen. The filter chamber is provided on the air intake pipe, and the filter screens are equidistantly arranged inside the filter chamber. The filter screens filter impurities in the air drawn into the filter chamber. The filter chamber is symmetrically provided with fixing seats inside, and the fixing seats are connected to the filter screens by bolts.

[0009] As a preferred technical solution of this utility model, the filter screen is provided with three sets, wherein the three sets of filter screens have different mesh sizes and are arranged according to the mesh size, so as to filter particles, dust and other impurities of different sizes step by step.

[0010] As a preferred technical solution of this utility model, it also includes a conveying component. The conveying component is installed at the air outlet at the top of the air heating component, and the conveying component conveys the gas output by the air heating component to the target location.

[0011] As a preferred technical solution of this utility model, the conveying component includes a connecting pipe, a connecting tube, and a discharge pipe. The air outlet of the constant temperature machine body is equipped with a connecting pipe, the top of the connecting pipe is equipped with a connecting tube, multiple sets of connecting tubes are provided, the end of the connecting tube is connected to a discharge pipe, the bottom of the discharge pipe is provided with a hot air discharge end, and a U-shaped air outlet is opened on the hot air discharge end.

[0012] As a preferred embodiment of this utility model, the inner walls of both the connecting pipe and the discharge pipe are covered with an insulation layer to reduce the heat loss of the air transported in the connecting pipe and the discharge pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, a negative pressure pump is used to draw external air into the filter chamber through an air inlet pipe. A filter screen filters out dust, particulate matter, and other impurities from the air, preventing them from entering the thermostat and affecting its operation, thus ensuring the air reaches the desired temperature and humidity. The filtered air is then fed into the thermostat through the air inlet pipe. Under the operation of the thermostat, the air temperature and humidity are processed and controlled, achieving stable control and guaranteeing the drying effect of the mold shells. Furthermore, the conveying component in this invention stably delivers the heated air, changing the traditional method of directly blowing in heated air with a blower or hot air fan. This allows the heated air to enter the drying chamber as fresh air, drying the mold shells within. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0027] like Figure 1 and Figure 2 The diagram shows the structure of the shell drying chamber in this embodiment. This chamber dries the shells placed inside, removing excess moisture and ensuring their quality. The drying chamber includes an air heating assembly 1, a conveying assembly 2, and a control box 3. Notably, the air heating assembly 1, conveying assembly 2, and control box 3 are placed inside the chamber. Through their operation, the shells placed inside are heated. The air heating assembly 1, conveying assembly 2, and control box 3, in conjunction with the enclosed room, form the drying chamber. The control box 3 is installed on the side of the air heating assembly 1. The temperature and humidity of the air heated by the air heating component 1 are controlled. When drying the mold shell, the air temperature is maintained at 23-29℃ and the humidity at 40-75%RH to facilitate the stable reception and drying of the mold shell in the subsequent process. The conveying component 2 is installed on the top of the air heating component 1 and is connected to the air outlet of the air heating component 1. The air heating component 1 draws in external air and then inputs the air into the air heating component 1. Through its own operation, the air temperature and humidity are controlled. Then, the air with a specific temperature and humidity is discharged through the conveying component 2. Under the conveying of the conveying component 2, the air dries the mold shell in the drying chamber.

[0028] As attached Figure 2 , Figure 3 and Figure 6As shown, this is a schematic diagram of the air heating component 1 in this embodiment. The air heating component 1 includes a thermostat body 11, a negative pressure pump body 12, and an air intake pipe 13. The thermostat body 11 is an existing DEJA-100 thermostat, with a temperature control range of -40℃ to +150℃ and a humidity range of 30% to 98%RH. This is existing technology and will not be described in detail. The negative pressure pump body 12 is installed inside the thermostat body 11, and the air intake pipe 13 is installed at the air inlet end of the negative pressure pump body 12. An air intake pipe 15 is installed at the air outlet end of the negative pressure pump body 12. Through the operation of the negative pressure pump body 12, gas enters the negative pressure pump body 12 through the air intake pipe 13, and then the gas is input into the thermostat body 11 through the air intake pipe 15. This facilitates the thermostat body 11 to control the temperature and humidity of the air input through the air intake pipe 15. A filter component 14 is installed on the air intake pipe 13 to filter the intake air.

[0029] Under the operation of the negative pressure pump body 12, external air is drawn in and enters the filter assembly 14 through the air intake pipe 13. Under the operation of the filter assembly 14, dust, particulate matter and other impurities in the drawn-in air are filtered out, making the air entering the constant temperature machine body 11 purer. This reduces the impact of dust, particulate matter and other impurities on air heating and humidity control, making it easier for the constant temperature machine body 11 to process the air, keeping the air temperature at around 26°C and the humidity at around 55%. After that, the processed air is input into the conveying assembly 2, allowing the processed air to stably dry the shell in the drying chamber.

[0030] As attached Figure 4 As shown, this is a schematic diagram of the structure of the filter assembly 14 in this embodiment. The filter assembly 14 includes a filter chamber 141, a filter screen 142, and a fixing seat 143. The filter chamber 141 is installed on the air intake pipe 13 and passes through the filter chamber 141. The fixing seats 143 are symmetrically installed at equal intervals inside the filter chamber 141, and the filter screen 142 is arranged between the fixing seats 143. Gas enters into the filter chamber 141 through the air intake pipe 13. By using the filter screen 142 in the filter chamber 141, dust, particulate matter, and other impurities in the air are filtered to prevent impurities from entering the constant temperature machine body 11 and affecting the subsequent air processing by the constant temperature machine body 11, thus preventing the air temperature and humidity from failing to reach the predetermined values.

[0031] It is worth noting that there are multiple sets of filter screens 142. The mesh size of the filter screens 142 varies depending on the different impurities in the air being filtered, allowing the filter screens 142 to filter the impurities in the air step by step. The filter screens 142 are installed on the fixing base 143 by bolts, which facilitates the replacement and maintenance of the filter screens 142 by subsequent operators.

[0032] As attached Figure 5 As shown, this is a schematic diagram of the conveying component 2 in this embodiment. The conveying component 2 includes a connecting pipe 21, a connecting pipe 22, a discharge pipe 23, and a hot air discharge end 24. The connecting pipe 21 is installed at the air outlet at the top of the thermostat body 11. The air output from the thermostat body 11 enters the connecting pipe 21. The end of the connecting pipe 21 is connected to the connecting pipe 22. There are multiple sets of connecting pipes 22. The number of connecting pipes 22 is adjusted according to the length of the conveying path. It is worth noting that the connecting pipes 22 are quickly connected by bolts. The end of the connecting pipe 22 is connected to the discharge pipe 23. The bottom end of the discharge pipe 23 is equipped with a hot air discharge end 24. The hot air discharge end 24 is provided with a U-shaped groove to facilitate the air in the connecting pipe 21 to enter the discharge pipe 23 through the connecting pipe 22. With the cooperation of the hot air discharge end 24, the air is discharged from the target position to dry the shell in the designated area.

[0033] In use, the connecting pipes 22 are spliced ​​together, and then the exhaust pipe 23 is installed at the designated position. The heated air is discharged through the hot air exhaust end 24 at the bottom of the exhaust pipe 23 to heat the mold shells in the mold shell placement area. This method changes the traditional method of directly blowing hot air, and precisely controls the temperature and humidity in the air to prevent insufficient air humidity from causing the mold shells to dry and crack or break. This ensures the overall stability of the drying chamber. The U-shaped structure of the hot air exhaust end 24 allows the heated air to dry the mold shells from multiple angles and directions, achieving efficient drying of the mold shells.

[0034] It is worth noting that both the connecting pipe 22 and the discharge pipe 23 are insulated conveying pipes, which reduces the loss of heat in the air when the air is conveyed in the conveying assembly 2.

[0035] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
