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.

[0060] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0061] (1) When detecting the mold in this solution, if the outside of the mold deforms, it will push the detection plate, and the deflection of the detection plate will apply an extrusion force to the first pressure sensor.

[0062] (2) In this solution, each airbag is marked in advance. When there is a local protrusion on the outer surface of the mold, this local area will squeeze the corresponding airbag bubble. Since the airbag bubble is closely attached to the mold surface, it can accurately reflect the minute deformation of the mold. When the airbag bubble is squeezed and triggers the elastic sheet to contact the conductive block, the controller can immediately identify which airbag bubble has been squeezed, thereby accurately positioning the deformation position of the mold.

[0063] (3) In this solution, when the mold deforms and cracks at the small cavity and small bubble locations, the liquid will enter the small cavity and small bubble, resulting in a decrease in the water pressure inside the mold. The value detected by the second pressure sensor will also correspondingly decrease, indicating that there is deformation inside the mold, thus realizing the detection of the inside of the mold.

[0077] 2. The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0078] Please refer to Figures 1 to 10 , a pressure detection device for the production of an electronic cigarette case mold, including an upper pressing plate 2 and a lower pressing plate 1. The upper pressing plate 2 is arranged above the lower pressing plate 1, and the middle parts of both the upper pressing plate 2 and the lower pressing plate 1 are designed with hollow openings; a limiting groove 3 is opened on the adjacent surfaces of the upper pressing plate 2 and the lower pressing plate 1, and the limiting groove 3 is opened at the hollow parts of the upper pressing plate 2 and the lower pressing plate 1; a first cylinder 4 is installed at the upper end of the upper pressing plate 2; two groups of detection plates 6 are provided, which are respectively arranged at the hollow parts of the upper pressing plate 2 and the lower pressing plate 1; a second cylinder 5 is arranged above the upper group of detection plates 6, and the second cylinder 5 is used to push the upper group of detection plates 6 to move up and down; a water injection assembly is arranged on the lower pressing plate 1, and the water injection assembly includes a water nozzle pipe 20, and the water nozzle pipe 20 is used to inject liquid into the injection port of the mold 43; two groups of detection components are provided, which are respectively installed on the opposite back surfaces of the two groups of detection plates 6, and the detection components on the two groups of detection plates 6 are symmetrically arranged. The detection component includes a first pressure sensor 11, and the first pressure sensor 11 is used to monitor whether the detection plate 6 will deflect when it is deformed and extruded by the mold 43; multiple groups of limiting columns 7 are provided, and the multiple groups of limiting columns 7 are movably inserted into the upper pressing plate 2, and the lower ends of the limiting columns 7 are fixedly connected to the lower pressing plate 1; a fixing plate 8 is fixedly connected to the upper ends of the limiting columns 7, and both the first cylinder 4 and the second cylinder 5 are installed on the fixing plate 8;

[0079] The detection assembly further includes two extrusion columns 14 which are respectively installed on the opposite sides of the two detection plates 6; a movable block 12 which is arranged at the end of the extrusion column 14 away from the detection plate 6; a conical groove 13 which is formed on the movable block 12, and the end of the extrusion column 14 away from the detection plate 6 extends into the conical groove 13, and the end of the extrusion column 14 located in the conical groove 13 is designed to be hemispherical; a sleeve 10 which is sleeved outside the movable block 12, a first pressure sensor 11 is arranged in the sleeve 10, and the first pressure sensor 11 is located at the end of the movable block 12 away from the extrusion column 14; a mounting plate 45 which is installed at the end of the sleeve 10 away from the detection plate 6, the mounting plate 45 in the upper detection assembly is fixedly connected with the output end of the second cylinder 5, and the mounting plate 45 in the lower detection assembly is fixedly connected with the lower end of the lower pressing plate 1; a plurality of first springs 9 which are fixedly connected between the mounting plate 45 and the detection plate 6; a controller which is installed on the lower pressing plate 1 and is electrically connected with the first pressure sensor 11.

[0080] By adopting the above technical solution, first, after the mold 43 is closed, it is placed in the limiting groove 3 on the lower pressing plate 1, and the injection port of the mold 43 faces the water nozzle pipe 20. Then, the first cylinder 4 and the second cylinder 5 work. The first cylinder 4 pushes the upper pressing plate 2 to move downward. Finally, the upper end of the mold 43 will be stuck into the limiting groove 3 in the upper pressing plate 2. Under the push of the first cylinder 4, the upper pressing plate 2 and the lower pressing plate 1 clamp the upper mold 432 and the lower mold 431. It should be noted that the mold 43 is composed of the upper mold 432 and the 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 face of the upper mold 432. After the lower set of detection plates 6 are placed in the limiting groove 3 of the lower pressing plate 1 when the mold 43 is placed, the lower end face of the lower mold 431 in the mold 43 will automatically fit with the lower set of detection plates 6. 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 injection assembly, and the liquid in the mold 43 is maintained at a certain water pressure threshold. By simulating the pressure inside the mold 43 during use and setting a water pressure threshold higher than that in daily use, the strength and tightness of every part of the inner wall of the mold 43 can be comprehensively detected. This high-strength water pressure test ensures the stability and durability of the mold 43 under extreme conditions, improves product quality and production safety. By using high-strength water pressure to squeeze every part of the inner wall of the mold 43, every part of the inner wall of the mold 43 is detected. In addition, 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 change that occurs 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 a decrease in material properties, so as to ensure the stability and reliability of the mold 43 in a high-temperature working environment. If the hardness of a local part of the mold 43 is not strong during the detection period, the local part will deform and bulge outward, so that the outside of the mold 43 has a bulging deformation. The local bulging part will squeeze the detection plate 6. After being squeezed, the detection plate 6 will deflect, thus driving the extrusion column 14 to deflect. When the extrusion column 14 deflects, the ball head at its end will squeeze the inner wall of the tapered groove 13. Because the inner wall of the tapered groove 13 is inclined, the inner wall of the tapered groove 13 will drive the movable block 12 to move towards the first pressure sensor 11 after being squeezed, realizing the extrusion of the first pressure sensor 11. The change in the value detected by the first pressure sensor 11 can directly reflect the local performance problem of the mold 43, providing accurate data support for the subsequent repair or improvement of the mold 43. This detection method can comprehensively detect the quality of the mold 43 before production, effectively prevent unqualified molds 43 from entering the production line, and reduce production interruptions and scrap rates caused by mold 43 problems.

[0081] In some embodiments of the present invention, the detection component further includes an airbag 15. Multiple groups of airbags 15 are provided, and the multiple groups of airbags 15 are installed on the side of the detection plate 6 away from the extrusion column 14; a conductive block 18 is disposed inside the airbag 15, and the conductive block 18 is fixedly connected to the detection plate 6; an elastic sheet 16 is disposed on the side of the conductive block 18 away from the detection plate 6. The elastic sheet 16 is separated from the conductive block 18 in the free state, and the elastic sheet 16 is made of a conductive material; a conductive column 17 is installed at one end of the elastic sheet 16, and the conductive column 17 is fixedly connected to the detection plate 6. The conductive column 17 and the conductive block 18 are respectively electrically connected to the controller.

[0082] By adopting the above technical solution, the controller marks each airbag 15 in advance. When the two detection plates 6 are attached to the upper and lower ends of the mold 43, the airbags 15 on the corresponding detection plates 6 are also attached to the surface of the mold 43. When there is a local protrusion on the outer surface of the mold 43, this local area will squeeze the airbag 15. The airbag 15 is made of a flexible material. After being squeezed, the airbag 15 deforms and squeezes the elastic sheet 16. The elastic sheet 16 deforms 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 at this place is connected. Because the controller marks each airbag 15 in advance, when the elastic sheet 16 contacts the conductive block 18, it can be known which group of airbags 15 is deformed by the squeezing force, so that the local deformation position of the mold 43 can be accurately found.

[0083] In some embodiments of the present invention, the water injection component further includes a water box 19, and the water box 19 is installed at one end of the water nozzle pipe 20; a water tank 23 is disposed below the lower pressing plate 1; a water guide pipe 21 is installed on one side of the water box 19, and the end of the water guide pipe 21 away from the water box 19 is connected to the water tank 23; a water pump 22 is installed on the water guide pipe 21, and the water pump 22 is used to extract the liquid in the water tank 23 and convey it to the water nozzle pipe 20 through the water guide pipe 21; two sets of slide bars 41 are provided, and the two sets of slide bars 41 are slidably connected to the lower end of the water box 19; a fourth cylinder 40, and 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 pressing plate 1.

[0084] 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 to approach the mold 43. The two sets of slide bars 41 provide stability for the movement of the water box 19. Finally, the water nozzle pipe 20 will be inserted into the injection port of the mold 43. At this time, the water pump 22 extracts the liquid in the water tank 23, conveys it to the water box 19 through the water guide pipe 21, and then conveys it to the water nozzle pipe 20 through the water box 19, and realizes the water injection work into the mold 43 through the water nozzle pipe 20.

[0085] In some embodiments of the present invention, it includes a control box 34. The control box 34 is installed on the inner wall of the water box 19. The inside of the control box 34 is in communication with the inside of the water guide pipe 21. A liquid discharge hole is provided on the right side wall of the control box 34; an electromagnet 35 is installed on the inner bottom of the control box 34, and the electromagnet 35 is electrically connected to the controller; a magnetic conduction block 36 is arranged above the electromagnet 35; a third spring 37 is fixedly connected to the upper end of the magnetic conduction block 36, and the upper end of the third spring 37 is fixedly connected to the inner wall of the corresponding water box 19.

[0086] 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 conduction block 36, causing the magnetic conduction block 36 to move downward. Finally, the magnetic conduction block 36 closely adheres to the electromagnet 35, realizing the sealing of the opening of the water guide pipe 21.

[0087] In some embodiments of the present invention, it includes an extrusion box 24. The extrusion box 24 is installed at the upper end of the water box 19. The inside of the extrusion box 24 is in communication with the inside of the water box 19; a partition plate 25 is fixedly installed on the inner wall of the extrusion box 24. The partition plate 25 divides the extrusion box 24 into two left and right cavities; a piston plate 27 is arranged in the right cavity of the extrusion box 24; a third air cylinder 26 is embedded in the upper end wall of the extrusion box 24, and the output end of the third air cylinder 26 is fixedly connected to the piston plate 27; a force-bearing plate 28 is arranged in the left cavity of the extrusion box 24; a connecting column 30 is fixedly connected to the upper end of the force-bearing plate 28; a second spring 29 is sleeved on the connecting column 30; a cross plate 31 is fixedly connected to the inner wall of the left cavity of the extrusion box 24, and the upper end of the connecting column 30 movably penetrates through the cross plate 31 and extends out; a limiting plate 32 is fixedly connected to the upper end of the connecting column 30; a second pressure sensor 33 is in the left cavity of the extrusion box 24, and the second pressure sensor 33 is located above the limiting plate 32. The second pressure sensor 33 is electrically connected to the controller.

[0088] By adopting the above technical solution, after the opening of the water guide pipe 21 is blocked, the third cylinder 26 will drive the piston plate 27 to move downward and squeeze the liquid in the extrusion box 24. Since 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 the downward movement of the piston plate 27, and the hydraulic pressure in the water box 19 is also increased. At this time, the force-bearing plate 28 moves upward and drives the connecting column 30 to move upward. Finally, the connecting column 30 drives the limiting 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 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.

[0089] In addition, if there are small cavities 44 or small air bubbles in the side wall of the mold 43 due to material problems, the strength at the locations with small cavities 44 and small air bubbles will be greatly reduced during the detection period of the mold 43. The mold 43 deforms and cracks at the locations of the small cavities 44 and small air bubbles, and the liquid will enter the small cavities 44 and small air bubbles, resulting in a decrease in the water pressure in the mold 43. Then, the value detected by the second pressure sensor 33 will also decrease correspondingly, indicating that the interior of the mold 43 has 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 be used to determine that the mold 43 has deformed, that is, it is concluded that the quality of the produced mold 43 is unqualified and needs to be repaired.

[0090] In some embodiments of the present invention, it includes a third pressure sensor 38, which is embedded and installed on the surface of the water box 19 where the water nozzle pipe 20 is installed, and the third pressure sensor 38 is electrically connected to the controller; a rubber pad 39, which is installed on the surface of the water box 19 where the water nozzle pipe 20 is installed.

[0091] By adopting the above technical solution, when the fourth cylinder 40 pushes the water box 19 towards the mold 43, finally the water box 19 will stick to the mold 43. By setting the rubber pad 39, the water box 19 squeezes the rubber pad 39 to ensure the sealing performance when injecting water into the mold 43 and avoid water leakage problems. 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 for the third pressure sensor 38, when the water box 19 squeezes the rubber pad 39 to reach the threshold, the fourth cylinder 40 can be stopped from continuing to push forward, and it is only necessary to ensure that the fourth cylinder 40 maintains this state. In this way, excessive squeezing force exerted by the water box 19 on the rubber pad 39 is avoided.
