The inventor found the following problems in the prior art during the implementation of the utility model:

[0004] The existing aluminum die casting machine does not have air tightness detection performance, and poor air tightness will affect the mechanical properties, corrosion resistance and other properties of the casting. In some products with strict precision requirements, such as automobile engine housings, the air tightness directly affects the performance of the product. Most traditional aluminum die casting machines do not have a guide assembly, which causes the mold to shift during the mold closing process, resulting in liquid leakage when injecting aluminum liquid into the mold, and the precision of the aluminum casting produced is also reduced.

[0005] Therefore, the aluminum die casting machine with air tightness detection effect is proposed to solve the above problems. SUMMARY

[0007] To achieve the above objectives, this utility model provides the following technical solution: an aluminum die-casting machine with airtightness detection effect, comprising a die-casting mechanism, an air extraction component, a liquid storage component, and an air pressure sensor. The air pressure sensor is placed on the side of the die-casting mechanism, and the liquid storage component is placed below the air pressure sensor. The air extraction component is installed below the liquid storage component. The die-casting mechanism includes a mold component, a telescopic component, and a guide component. The guide component is installed on the side of the mold component, and the telescopic component is installed on the side of the mold component away from the guide component.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] Compared with existing technologies, this aluminum die-casting machine with airtightness detection function uses a combination of air pressure sensor and air extraction component to detect the airtightness of the aluminum die-casting machine. First, the worker needs to use the air extraction component to remove the air from inside the aluminum die-casting machine, so that the inside of the aluminum die-casting machine is in a low-pressure state. Then, the value on the air pressure sensor is observed for a period of time. If the pressure on the air pressure sensor increases after a period of time, it means that the aluminum die-casting machine is leaking. The location of the leak needs to be detected and repaired in time. If the value on the air pressure sensor does not change significantly, it means that the aluminum die-casting machine is airtight.

Furthermore, it prevents leakage during the injection molding and cooling process. In use, the guide rod of the guide component moves into the guide column under the push of the telescopic component. The side wall of the guide column is embedded with steel balls, which reduce friction between the guide rod and the guide column when they enter, making the mold closing more smoothly.

[0021] 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 1

[0022] As attached Figures 1 to 4The aluminum die-casting machine shown includes a die-casting mechanism 1, an air extraction component 2, a liquid storage component 3, and a pressure sensor 4. The pressure sensor 4 is placed on the side of the die-casting mechanism 1, the liquid storage component 3 is placed below the pressure sensor 4, and the air extraction component 2 is installed below the liquid storage component 3. The die-casting mechanism 1 includes a mold component 5, a telescopic component 6, and a guide component 7. The guide component 7 is installed on the side of the mold component 5, and the telescopic component 6 is installed on the side of the mold component 5 away from the guide component 7.

[0023] The die-casting mechanism 1 processes molten aluminum into die-cast parts; the air extraction assembly 2 extracts air from inside the die-casting machine; the liquid storage assembly 3 provides space for the molten aluminum; and the pressure sensor 4 is a sensor used to measure the absolute pressure of a gas. The pressure sensor 4 converts external pressure changes into electrical signals through a pressure-sensitive element. These signals are then amplified, filtered, linearized, and temperature-compensated by a signal processing circuit before being digitally output, allowing users to see the internal pressure of the die-casting machine. The pressure sensor 4 is model PSE561. The pressure sensor 4 is placed on the side of the die-casting mechanism 1, and the liquid storage assembly 3 is placed below it. The air extraction assembly 2 is installed below the liquid storage assembly 3, and the liquid storage assembly 3 and the air extraction assembly 2 are connected by threads. The die-casting mechanism 1 includes a mold assembly 5, a telescopic assembly 6, and a guide assembly 7. The mold assembly 5 can... The aluminum liquid is shaped by the telescopic component 6, which allows the second mold 15 to move horizontally. The guide component 7 ensures that the mold component 5 does not shift its position when it is merged. The guide component 7 is bolted to the side of the mold component 5, and the telescopic component 6 is bolted to the side of the mold component 5 away from the guide component 7. When producing die-cast parts, the worker needs to first remove the air from the die-casting machine and then observe the change in the value on the air pressure sensor 4 for a period of time. If there is no significant change, the aluminum die-casting can proceed. During the production of aluminum die-cast parts, the worker needs to first pour the aluminum liquid into the liquid storage component 3 and then start the die-casting machine. After the die-casting machine is started, the telescopic component 6 in the die-casting mechanism 1 will push the mold component 5 to merge along the guide component 7. After the mold component 5 is merged, the aluminum liquid pump will pump the aluminum liquid from the liquid storage component 3 into the mold component 5 to complete the processing. Example 2

[0024] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0025] In a preferred embodiment, the gas extraction assembly 2 includes a vacuum pump 8, a gas extraction pipe 9, and a first valve 10. The vacuum pump 8 extracts gas from the die-casting machine.

The gas extraction pipe 9 is installed above the vacuum pump 8, and the vacuum pump 8 and the gas extraction pipe 9 are connected by threads. The first valve 10 is installed above the gas extraction pipe 9, and the gas extraction pipe 9 and the first valve 10 are connected by threads.

[0026] In a preferred embodiment, the liquid storage assembly 3 includes an inlet pipe 11, a second valve 12, and a liquid storage tank 13. The inlet pipe 11 connects the liquid storage assembly 3 to an external aluminum liquid storage tank. The second valve 12 controls the opening and closing of the liquid storage assembly 3. The liquid storage tank 13 provides a space for placing the aluminum liquid. The second valve 12 is installed on the side of the inlet pipe 11, and the inlet pipe 11 and the second valve 12 are connected by threads. The liquid storage tank 13 is installed on the side of the second valve 12 away from the inlet pipe 11, and the second valve 12 and the liquid storage tank 13 are connected by threads.

[0027] In a preferred embodiment, the mold assembly 5 includes a first mold 14, a second mold 15, and a sealing strip 16. The first mold 14 and the second mold 15 are closed to process the molten aluminum. The sealing strip 16 can prevent the molten aluminum from flowing out of the mold. The sealing strip 16 is adhered to the side of the first mold 14, and the second mold 15 is adhered to the side of the sealing strip 16 away from the first mold 14.

[0028] In a preferred embodiment, the telescopic assembly 6 includes a cylinder 17, a telescopic rod 18, and a connecting rod 19. The cylinder 17 powers the telescopic assembly 6, the telescopic rod 18 connects the cylinder 17 and the connecting rod 19, and the connecting rod 19 connects the telescopic assembly 6 and the mold assembly 5. The telescopic rod 18 is mounted on the side of the cylinder 17, and the cylinder 17 and the telescopic rod 18 are connected by threads. The connecting rod 19 is bolted to the side of the telescopic rod 18 away from the cylinder 17.

[0029] In a preferred embodiment, the guide assembly 7 includes a connecting plate 20, a guide rod 21, and a guide post 22. The connecting plate 20 connects the guide rod 21 and the second mold 15. The guide post 22 provides a space for the guide rod 21 to pass through when it is horizontally displaced. The guide rod 21 is bolted to the side of the connecting plate 20, and the guide post 22 is placed on the side of the guide rod 21 away from the connecting plate 20.

[0030] The working process of this utility model is as follows: First, when it is necessary to produce die-cast parts, the worker needs to test the sealing performance of the aluminum die-casting machine. The worker first uses the air extraction assembly 2 to remove the air from inside the aluminum die-casting machine. When using the air extraction assembly 2, the worker needs to open the first valve 10 and turn on the vacuum pump 8. The vacuum pump 8 will extract the air from the die-casting machine, and the extracted air will be discharged outside the die-casting machine through the air extraction pipe 9. After extraction is complete, the worker needs to close the first valve 10 and the vacuum pump 8. At this time, the inside of the aluminum die-casting machine is in a low-pressure state. Then, the worker needs to observe the value on the air pressure sensor 4 for a period of time. If, after a period of time, the air pressure sensor... If the pressure on pressure sensor 4 increases, it indicates an air leak in the aluminum die-casting machine. The leak needs to be located and repaired promptly. If the value on pressure sensor 4 shows no significant change, the aluminum die-casting machine is airtight and production can proceed to the next step. First, the worker needs to connect the container holding the molten aluminum to the inlet pipe 11 of the liquid storage component 3 via a threaded connection. Then, the second valve 12 is opened, and the molten aluminum is pumped into the storage tank 13 using an aluminum pump. After pumping out the molten aluminum, the worker needs to close the second valve 12 and then disconnect the connecting pipe to prevent air from entering the die-casting machine. Finally, the worker needs to turn on the die-casting machine. The casting machine automatically produces die-cast parts. During the die-casting process, the telescopic component 6 pushes the second mold 15 in the mold assembly 5 towards the first mold 14. When the first mold 14 and the second mold 15 close, the aluminum liquid pump next to the liquid storage component 3 draws aluminum liquid into the first mold 14, filling both the first mold 14 and the second mold 15. After cooling, the first mold 14 and the second mold 15 automatically separate, and the worker needs to remove the finished aluminum die-cast parts in a timely manner. During the operation of the die-casting assembly, the cylinder 17 in the telescopic component 6 pushes the connecting rod 19 horizontally through the telescopic rod 18. The connecting rod 19 and the mold assembly 5... Fixed by bolts, when the connecting rod 19 moves horizontally, the second mold 15 in the mold assembly 5 also moves horizontally along the guide assembly 7. As the second mold 15 approaches the first mold 14, the connecting block of the guide assembly 7 pushes the guide rod 21 to move into the guide post 22. The inner side of the guide post 22 is equipped with ball bearings, which can effectively reduce the friction between the guide rod 21 and the guide post 22. When the first mold 14 and the second mold 15 are combined, the sealing strip 16 between the molds will make the inside of the mold absolutely sealed, preventing the aluminum liquid from leaking at the edge of the mold. The above is the working principle of this aluminum die-casting machine with airtightness detection effect.
