Description

Technical Field

[0001] The present invention relates to the field of mold detection technology, and more specifically, to a pressure detection device for producing an electronic cigarette shell mold. Background Art

[0002] As an important part of electronic cigarettes, the manufacturing quality of electronic cigarette shells is directly related to the overall appearance and durability of electronic cigarettes. Usually, electronic cigarette shells are made of plastic materials through injection molding, and this process is inseparable from precision molds. The production of molds involves fine processing of the blanks through CNC (computer numerical control) machine tools to ensure the accuracy and durability of the molds. After processing, the molds must undergo strict testing to verify whether they meet the use standards, so as to ensure that stable performance and high precision can be maintained in the subsequent electronic cigarette shell production process.

[0003] However, in current technical practice, there are certain limitations in the mold detection method. The traditional detection method usually selects several detection points on the mold surface, uses a hardness tester to press these points, and judges whether the hardness of each detection point meets the standard based on the reading of the hardness tester, and then infers whether the overall strength of the mold meets the requirements. Although this method can effectively evaluate the quality of the mold to a certain extent, it has a significant defect: if there are areas with insufficient local strength in the mold, and these areas are not selected as detection points, then even if the hardness tests of all selected detection points are qualified, the mold may still be damaged prematurely during actual use due to these undetected weaknesses. This situation will not only cause the mold to quickly lose accuracy during use, but may also directly affect the production quality and efficiency of the electronic cigarette shell, and even cause production interruption in severe cases.

[0004] In view of this situation, the present invention has made in-depth improvements and innovations on the existing mold detection technology, and designed and developed a pressure detection equipment for the production of electronic cigarette shell molds. The equipment aims to overcome the limitations of traditional detection methods through more comprehensive and scientific detection means, and realize a comprehensive and high-precision evaluation of mold strength.

A pressure sensor 11 is located at one end of the movable block 12 away from the extrusion column 14; a mounting plate 45, the mounting plate 45 is installed at one end of the sleeve 10 away from the detection plate 6, the mounting plate 45 in a detection component at the upper end is fixedly connected to the output end of the second cylinder 5, and the mounting plate 45 in a detection component at the lower end is fixedly connected to the lower end of the lower pressure plate 1; a first spring 9, the first spring 9 is arranged in multiple groups, and the first spring 9 is fixedly connected between the mounting plate 45 and the detection plate 6; a controller, the controller is installed on the lower pressure plate 1, and the controller is electrically connected to the first pressure sensor 11.

[0025] By adopting the above technical scheme, the mold 43 is firstly closed and placed in the limiting groove 3 on the lower pressing plate 1, and the injection port of the mold 43 is directed toward the water nozzle pipe 20, and then the first cylinder 4 and the second cylinder 5 work, the first cylinder 4 pushes the upper pressing plate 2 to move downward, and finally the upper end of the mold 43 will be stuck in the limiting groove 3 in the upper pressing plate 2, and the upper pressing plate 2 and the lower pressing plate 1 are clamped by the push of the first cylinder 4. It should be noted that the mold 43 is composed of an upper mold 432 and a lower mold 431; the second cylinder 5 will push the detection plate 6 to move downward, so that the detection plate 6 is attached to the upper end surface of the upper mold 432, and the detection plate 6 of the lower end group is placed in the limiting groove 3 in the lower pressing plate 1 when the mold 43 is placed. After the groove 3 is positioned, the lower end surface of the lower mold 431 in the mold 43 will automatically fit with the detection plate 6 of the lower end group, and then the water nozzle pipe 20 is inserted into the injection port of the mold 43, and liquid is injected into the mold 43 through the water injection component, and the liquid in the mold 43 is at a certain water pressure threshold. By simulating the pressure inside the mold 43 when in use and setting a water pressure threshold higher than that of daily use, the strength and sealing of each part of the inner wall of the mold 43 can be fully tested. This high-intensity water pressure test ensures the stability and durability of the mold 43 under extreme conditions, improves product quality and production safety, and squeezes water from every part of the inner wall of the mold 43 through high-intensity water pressure, so that every part of the inner wall of the mold 43 is tested, and another The water pressure inside the mold 43 is maintained for a certain period of time, such as 30 minutes or one hour, etc. The specific time can be determined according to the experimental situation. During the detection process, the liquid injected into the mold 43 is heated to simulate the thermoplastic changes that occur in the mold 43 during daily use. This step helps to discover potential problems of the mold 43 in a high temperature environment, such as deformation, cracks, or degradation of material properties, thereby ensuring the stability and reliability of the mold 43 in a high temperature working environment. If the mold 43 has a local hardness that is not strong during the detection period, the local part will deform and bulge outward, thereby causing a bulge deformation on the outside of the mold 43. The local bulge will squeeze the detection plate 6, and the detection plate 6 will be squeezed after being squeezed. Deflection causes the extrusion column 14 to deflect. When the extrusion column 14 deflects, the ball head thereof will squeeze the inner wall of the conical groove 13. Because the inner wall of the conical groove 13 is inclined, the inner wall of the conical groove 13 will drive the movable block 12 to move toward the first pressure sensor 11 after being squeezed, thereby squeezing the first pressure sensor 11. The change in the numerical value detected by the first pressure sensor 11 can directly reflect the local performance problem of the mold 43, and provide accurate data support for the subsequent repair or improvement of the mold 43. The detection method can perform a comprehensive quality inspection on the mold 43 before production, effectively prevent unqualified molds 43 from entering the production line, and reduce production interruptions and scrap rates caused by problems with the mold 43.

[0026] In some embodiments of the present invention, the detection component also includes an air bag 15, which is arranged in multiple groups, and the multiple groups of air bags 15 are installed on the side of the detection plate 6 away from the extrusion column 14; a conductive block 18, which is arranged in the air bag 15, and the conductive block 18 is fixedly connected to the detection plate 6; an elastic sheet 16, which is arranged on the side of the conductive block 18 away from the detection plate 6, and the elastic sheet 16 is separated from the conductive block 18 when in a free state, and the elastic sheet 16 is made of conductive material; a conductive column 17, which is installed at one end of the elastic sheet 16, and the conductive column 17 is fixedly connected to the detection plate 6, and the conductive column 17 and the conductive block 18 are electrically connected to the controller respectively.

[0027] By adopting the above technical solution, the controller marks each air bubble 15 in advance. When the two groups of detection plates 6 are attached to the upper and lower ends of the mold 43, the air bubbles 15 on the corresponding detection plates 6 are also attached to the surface of the mold 43. When a local bulge appears on the outer surface of the mold 43, the local area will squeeze the air bubble 15. The air bubble 15 is made of flexible material. After being squeezed, the air bubble 15 is deformed and squeezes the elastic sheet 16. The elastic sheet 16 is deformed and contacts the conductive block 18, and finally pushes the detection plate 6 to deflect. When the elastic sheet 16 contacts the conductive block 18, the controller will detect that the circuit is connected at this location. Because the controller marks each air bubble 15 in advance, when the elastic sheet 16 contacts the conductive block 18, it can be known which group of air bubbles 15 is deformed by the extrusion force, so that the local deformation position of the mold 43 can be accurately found.

[0028] In some embodiments of the present invention, the water injection assembly also includes a water box 19, which is installed at one end of the water nozzle pipe 20; a water tank 23, which is arranged below the lower pressure plate 1; a water pipe 21, which is installed on one side of the water box 19, and the end of the water pipe 21 away from the water box 19 is connected to the water tank 23; a water pump 22, which is installed on the water pipe 21, and the water pump 22 is used to extract the liquid in the water tank 23 and transport it to the water nozzle pipe 20 through the water pipe 21; a sliding plate 41, which is arranged in two groups, and the two groups of sliding plates 41 are slidably connected to the lower end of the water box 19; a fourth cylinder 40, the output end of the fourth cylinder 40 is installed on the side of the water box 19 away from the water nozzle pipe 20, and the fourth cylinder 40 is installed on the lower pressure plate 1.

[0029] By adopting the above technical solution, when it is necessary to inject liquid into the mold 43, the fourth cylinder 40 pushes the water box 19 closer to the mold 43, and the two sets of sliding strips 41 provide stability for the movement of the water box 19. Finally, the water nozzle tube 20 will be inserted into the injection port of the mold 43. At this time, the water pump 22 draws the liquid in the water tank 23, transports it to the water box 19 through the water pipe 21, and then transports it to the water nozzle tube 20 through the water box 19, and water is injected into the mold 43 through the water nozzle tube 20.

[0030] In some embodiments of the present invention, a control box 34 is included, which is installed on the inner wall of the water box 19. The interior of the control box 34 is interconnected with the interior of the water pipe 21, and a drainage hole is provided on the right side wall of the control box 34; an electromagnet 35, which is installed on the inner bottom of the control box 34 and is electrically connected to the controller; a magnetic block 36, which is arranged above the electromagnet 35; and a third spring 37, which is fixedly connected to the upper end of the magnetic block 36, and the upper end of the third spring 37 is fixedly connected to the corresponding inner wall of the water box 19.

[0031] By adopting the above technical solution, after the water injection is completed, the controller controls the electromagnet 35 to be energized, the electromagnet 35 generates magnetism and magnetically attracts the magnetic block 36, so that the magnetic block 36 moves downward, and finally the magnetic block 36 is close to the electromagnet 35 to achieve the blocking of the opening of the water pipe 21.

[0032] In some embodiments of the present invention, the extrusion box 24 is included, the extrusion box 24 is installed at the upper end of the water box 19, and the interior of the extrusion box 24 is connected to the interior of the water box 19; the partition plate 25, the partition plate 25 is fixedly installed on the inner wall of the extrusion box 24, and the partition plate 25 divides the extrusion box 24 into two left and right cavities; the piston plate 27, the piston plate 27 is arranged in the right cavity of the extrusion box 24; the third cylinder 26, the third cylinder 26 is embedded and installed on the upper end wall of the extrusion box 24, and the output end of the third cylinder 26 is fixedly connected to the piston plate 27; the force plate 28, the force plate 28 is arranged on the In the left cavity; a connecting column 30, the connecting column 30 is fixedly connected to the upper end of the force-bearing plate 28; a second spring 29, the second spring 29 is sleeved on the connecting column 30; a cross plate 31, the cross plate 31 is fixedly connected to the inner wall of the cavity on the left side of the extrusion box 24, and the upper end of the connecting column 30 movably passes through the cross plate 31 and extends out; a limiting plate 32, the limiting plate 32 is fixedly connected to the upper end of the connecting column 30; a second pressure sensor 33, the second pressure sensor 33 is in the cavity on the left side of the extrusion box 24, and the second pressure sensor 33 is located above the limiting plate 32, and the second pressure sensor 33 is electrically connected to the controller.

[0033] By adopting the above technical solution, after the opening of the water pipe 21 is sealed, the third cylinder 26 will drive the piston plate 27 to move downward and squeeze the liquid in the extrusion box 24. Because the interiors of the extrusion box 24, the water box 19 and the mold 43 are interconnected, the hydraulic pressure in the mold 43 is increased by moving the piston plate 27 downward, and the hydraulic pressure in the water box 19 is also increased. At this time, the force plate 28 moves upward and drives the connecting column 30 to move upward. Finally, the connecting column 30 drives the limit plate 32 to squeeze the second pressure sensor 33. When the second pressure sensor 33 reaches the preset threshold, the third cylinder 26 stops pushing the piston plate 27 to move downward and maintains this state. In this way, a high pressure state can be maintained in the mold 43 to complete the detection of the mold 43.

[0034] In addition, if the mold 43 has small cavities 44 or small bubbles in the side wall due to material problems, the strength of the small cavities 44 and small bubbles will be greatly reduced during the detection period of the mold 43, and the mold 43 will be deformed and broken at the small cavities 44 and small bubbles. Liquid will enter the small cavities 44 and small bubbles, causing the water pressure in the mold 43 to decrease. In this way, the value detected by the second pressure sensor 33 will also decrease accordingly, indicating that the inside of the mold 43 is deformed. Even if no deformation is detected on the outside of the mold 43, the change in the value detected by the second pressure sensor 33 can also be used to determine that the mold 43 is deformed, that is, it is concluded that the quality of the produced mold 43 is unqualified and needs to be repaired.

[0035] In some embodiments of the present invention, a third pressure sensor 38 is included, which is embedded in the side of the water box 19 where the faucet tube 20 is installed, and the third pressure sensor 38 is electrically connected to the controller; a rubber pad 39 is installed on the side of the water box 19 where the faucet tube 20 is installed.

[0036] By adopting the above technical solution, when the fourth cylinder 40 pushes the water box 19 to approach the mold 43, the water box 19 will finally stick to the mold 43. By setting the rubber pad 39, the water box 19 squeezes the rubber pad 39 to ensure the sealing when water is injected into the mold 43, avoiding the problem of water leakage. After the rubber pad 39 is squeezed, the rubber pad 39 corresponding to the third pressure sensor 38 will deform and squeeze the third pressure sensor 38. By setting a threshold value for the third pressure sensor 38, when the water box 19 squeezes the rubber pad 39 to reach the threshold value, the fourth cylinder 40 can be stopped from continuing to push forward. It is only necessary to ensure that the fourth cylinder 40 maintains this state, thereby avoiding the water box 19 from applying excessive squeezing force on the rubber pad 39.

[0037] In some embodiments of the present invention, thermistors 42 are included. Thermistors 42 are arranged in multiple groups. Thermistors 42 are installed in the limiting grooves 3. Thermistors 42 are electrically connected to the controller.

[0038] By adopting the above technical solution, when hot liquid is injected into the mold 43, the mold 43 heats up. The thermal conductivity and heat dissipation of the mold 43 can be calculated through the spacing between the thermistors 42 and the detected temperature value. By understanding the thermal characteristics of the mold 43, the molding process of the product in the mold 43 can be better controlled, and defects caused by uneven temperature distribution, such as shrinkage holes and deformation, can be reduced, thereby improving the overall quality of the product.

[0039] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
