Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.
[0019] Referring to Figures 1 to 9 , the present application provides a mobile phone shell injection mold with automatic waste recycling, comprising a mold groove A 2 installed on the upper end of an operating table 1, a sliding groove is formed on the upper surface of the operating table 1, a mold groove B 3 driven by a pneumatic cylinder is slidably arranged in the sliding groove, and the mold groove A 2 and the mold groove B 3 are located on the same horizontal plane, a protrusion 36 is connected to the lower end of the mold groove A 2, a water gap 4 is formed on one side of the mold groove A 2, a pneumatic clamp 7 driven by a first electric push rod 6 is slidably arranged on the upper end of the operating table 1, a pneumatic shear 9 driven by a second electric push rod 8 is slidably arranged on one side of the pneumatic clamp 7, a grinding plate 10 is installed on one side of the pneumatic shear 9, a spray gun 11 is arranged between the pneumatic clamp 7 and the pneumatic shear 9, an air inlet pipe 12 is communicated at one end of the spray gun 11, a stop valve is arranged in the air inlet pipe 12, a gear 14 is rotatably arranged on one side of the air inlet pipe 12, and a rack 15 driven by the second electric push rod 8 is slidably arranged on one side of the gear 14; a pressure rod 17 is slidably arranged at the lower end of the rack 15, a push plate 19 is slidably arranged at the center of the interior of the operating table 1, a first through groove 20 and a second through groove 24 are formed on the upper surface of the operating table 1, and a limit plate 21 is slidably arranged in the first through groove 20. The air inlet pipe 12 is communicated with a guide pipe 31 on the outside, and the second through groove 24 is communicated with a separation groove 26 at the lower end, the filter plate 27 is inverted in the separation groove 26, and the lower end of the filter plate 27 is connected to one end of the guide pipe 31.
[0020] In an optional embodiment, the upper end of the operating table 1 is fixedly connected with a support frame 5, the upper end of the support frame 5 is installed with a first electric push rod 6 and a second electric push rod 8, the first electric push rod 6 and the second electric push rod 8 both extend to the lower end through the support frame 5, the spray gun 11 is embedded in the support frame 5, and the other end of the air inlet pipe 12 is connected with the fan. When the device is used, the cylinder drives the mold groove B3 to move and contact with the mold groove A2. After the mold groove B3 contacts with the mold groove A2, the raw material is injected into the mold groove A2 through the water gap 4 on one side of the mold groove A2, so as to plastic the mobile phone shell. After plastic, the mold groove B3 is reset by the cylinder.
[0021] In an optional embodiment, one end of the mold groove A2 is connected with a third electric push rod 18, the other end of the third electric push rod 18 penetrates through the mold groove A2 and is connected with a push plate 19, the lower end of the limiting plate 21 is fixedly connected with a spring A22, the other end of the spring A22 is connected with a support, and the other end of the support is connected with the lower end of the operating table 1. As described above, when the mold groove B3 contacts with the mold groove A2, the protrusion 36 at the lower end of the mold groove B3 will contact with the inclined block on one side of the limiting plate 21 at this time, so that the inclined block will be gradually pressed down with the movement of the protrusion 36. When the inclined block is lowered, the inclined block is fixedly connected with the limiting plate 21, so that the limiting plate 21 will be lowered synchronously when the inclined block is lowered, thereby preventing the limiting plate 21 from blocking the contact between the mold groove B3 and the mold groove A2. At the same time, as described above, after the mold groove B3 is reset, the pressing force of the protrusion 36 on the inclined block disappears, and then after the mold groove B3 is reset, the limiting plate 21 will be reset synchronously through the spring A22 at the lower end. After the limiting plate 21 is reset, the end of the limiting plate 21 away from the spring A22 is higher than the bottom of the mold groove A2, and then the limiting plate 21 will limit one end of the mobile phone shell after injection molding. After the limiting plate 21 is raised, the third electric push rod 18 will push the push plate 19 outward at this time. After the push plate 19 is pushed outward, the limiting plate 21 limits one end of the mobile phone shell after injection molding at this time, and then when the push plate 19 pushes the mobile phone shell to pop out from the inside of the mold groove A2, only the end close to the pneumatic clamp 7 of the mobile phone shell will protrude. At this time, the pneumatic clamp 7 gradually descends through the driving of the first electric push rod 6, and after the pneumatic clamp 7 descends to contact one end of the mobile phone shell, one end of the mobile phone shell is clamped and fixed. The connection between the push plate 19 and the mold groove A2 is a sealed connection, and then when injection molding, the raw material will not penetrate into the connection, so as not to affect the plastic of the mobile phone shell.
[0022] In an optional embodiment, the limiting plate 21 is fixedly connected with a fixed plate 23 at one end, the pressure rod 17 is dampingly connected with the second electric push rod 8, and the other end of the pressure rod 17 is in contact with the other end of the fixed plate 23. The side of the limiting plate 21 away from the mold groove A2 is fixedly connected with an inclined block. As described above, after the pneumatic clamp 7 clamps and fixes one end of the mobile phone shell, the second electric push rod 8 drives the pneumatic shear 9 to descend at this time. When the pneumatic shear 9 descends, it will synchronously drive the pressure rod 17 to descend. When the pressure rod 17 descends, it will extrude the fixed plate 23 to synchronously descend. Since the fixed plate 23 is connected with the limiting plate 21, the fixed plate 23 will synchronously drive the limiting plate 21 to descend when the fixed plate 23 descends, so as to make the limiting plate 21 disengage from limiting the mobile phone shell. After the limiting plate 21 disengages from limiting one end of the mobile phone shell, the mobile phone shell will be fixed by the pneumatic clamp 7 in a vertical posture. At this time, with the gradual descent of the pneumatic shear 9, the grinding plate 10 on one side of the pneumatic shear 9 will come into contact with the side of the mobile phone shell close to the water gap 4, thereby grinding the uneven part of the side edge of the mobile phone shell. (Because the injection pressure is too high, it exceeds the mold clamping force bearing range, so the melt may forcibly squeeze into the parting surface gap, causing more flash on one side of the water gap 4, which appears protruding). After the pneumatic shear 9 moves to a certain position, it will shear the protruding part inside the water gap 4 of the mobile phone shell during injection molding, thereby accurately shearing the protruding part inside the water gap 4 of the mobile phone shell by the pneumatic shear 9, preventing size deviation and uneven shearing that may occur during manual shearing, making the edge of the mobile phone shell smoother and neater, and improving the appearance quality and overall quality of the product. At the same time, the grinding of the edge of the mobile phone shell by the grinding plate 10 can remove the burrs and fly needles and other defects after injection molding, making the edge smooth and neat, improving the product feel and visual quality, and automatically processing waste, reducing labor and improving production efficiency. Because the pressure rod 17 is dampingly connected with the second electric push rod 8, when the pressure rod 17 descends and comes into contact with the upper end of the mold groove A2, the pressure rod 17 will be limited by the mold groove A2, thereby causing the pressure rod 17 to be unable to descend.
[0023] In an optional embodiment, the second electric push rod 8 is connected with a connecting rod 16 outside the damping connection, and the other end of the connecting rod 16 is fixedly connected with a rack 15, the rack 15 is engaged with a gear 14, the gear 14 is fixedly connected with a valve rod 13 at one end close to the air inlet pipe 12, the other end of the valve rod 13 extends through the air inlet pipe 12 to the inside and is connected with a stop valve, the stop valve inside the air inlet pipe 12 is in a closed state in the initial state, when the second electric push rod 8 drives the pneumatic shear 9 to descend, it will synchronously drive the connecting rod 16 to descend, when the connecting rod 16 descends, it will synchronously drive the rack 15 to descend, when the rack 15 descends, it will synchronously drive the gear 14 to rotate, when the gear 14 rotates, it will drive the stop valve inside the air inlet pipe 12 to open through the valve rod 13, after the stop valve is opened, the gas delivered by the fan will be delivered to the spray gun 11 through the air inlet pipe 12 and sprayed out, after the gas is sprayed out by the spray gun 11, the cold wind will be delivered to the clamped and fixed mobile phone shell, when the grinding plate 10 contacts the mobile phone shell, the cold wind will quickly cool the just plastic mobile phone shell, prevent the mobile phone shell from deforming at the edge due to friction when the grinding plate 10 contacts the mobile phone shell because the mobile phone shell is not completely cooled, at the same time, the wind force delivered by the spray gun 11 will apply a falling force to the mobile phone shell when the pneumatic clamp 7 releases the mobile phone shell, so that the mobile phone shell has a certain impact force in the process of falling through the first through slot 20 to the collecting groove B30 inside, thereby detecting the quality of the mobile phone shell, so that the cold wind sprayed out by the spray gun 11 can quickly cool and shape the just plastic mobile phone shell when the grinding plate 10 contacts the just plastic mobile phone shell, ensure that the size of the mobile phone shell after the edge is polished is accurate and the shape is regular, and the appearance and structure quality of the product are stably improved, at the same time, the wind force sprayed out by the operation table 1 applies an impact force to the mobile phone shell, thereby assisting in detecting the internal structure defects of the mobile phone shell, so that unqualified products are quickly screened out, the product quality is ensured, and the production efficiency is greatly improved.
[0024] In an optional embodiment, the operation table 1 is fixedly connected with a guide pipe 25 at the lower end, the guide pipe 25 is connected with the second through slot 24, and the other end of the guide pipe 25 is connected with a separation groove 26, after the waste material remaining at the edge of the mobile phone shell in the water gap 4 is sheared by the pneumatic shear 9, the waste material will fall through the second through slot 24 to the inside of the guide pipe 25, after the waste material enters the inside of the guide pipe 25, it will be delivered by the guide pipe 25 to the inside of the separation groove 26, after the waste material enters the inside of the separation groove 26, it will fall to the surface of the filter plate 27.
[0025] In an optional embodiment, the filter plate 27 is fixedly connected with a rotating shaft 28 at one end, the rotating shaft 28 is rotatably connected with the inner wall of the separation groove 26 at both ends, and the filter plate 27 is inclined, the inclination angle of the filter plate 27 is small, so that when the waste material falls to the upper surface of the filter plate 27, the waste material will not roll down through the inclination angle of the filter plate 27.
[0026] In an optional embodiment, the air inlet pipe 12 is fixedly connected with a connecting pipe 32 outside, the other end of the connecting pipe 32 is connected with a guide pipe 31, the guide pipe 31 is slidably connected with a top rod 33 inside, a pressure relief groove 34 is formed on the outside of the top rod 33 inside the guide pipe 31, one end of the top rod 33 is fixedly connected with a spring B 35, the other end of the spring B 35 is fixedly connected with the inner wall of the guide pipe 31, the other end of the top rod 33 is connected with the lower end of the filter plate 27, when the second electric push rod 8 drives the pneumatic shear 9 to reset, the pneumatic shear 9 resets with the second electric push rod 8, the second electric push rod 8 will drive the rack 15 and the pressure rod 17 to reset synchronously, and then the stop valve inside the air inlet pipe 12 will be closed again when the rack 15 resets, after the stop valve is closed, with the fan continuously conveying gas inside the air inlet pipe 12, at this time the gas will form pressure inside the air inlet pipe 12, so that the gas will enter the connecting pipe 32 inside due to the pressure, the connecting pipe 32 will convey the gas to the inside of the guide pipe 31, when the gas gradually increases inside the guide pipe 31, the gas pressure will gradually form, when the gas pressure gradually increases inside the guide pipe 31, the top rod 33 will be pushed to move outward, when the top rod 33 moves, the filter plate 27 will be lifted to a certain height, after the top rod 33 rises to a certain height, the pressure relief groove 34 will be in contact with the outside, and then the pressure relief groove 34 will quickly release part of the gas pressure inside the guide pipe 31, after the gas pressure inside the guide pipe 31 is released, the guide pipe 31 will quickly reset through the gravity of the filter plate 27 and the tension of the spring B 35, when the top rod 33 resets, the filter plate 27 will be quickly reset, and then the filter plate 27 will generate knocking vibration force in the process of quickly resetting, and the vibration force will be transmitted to the waste on the upper surface of the filter plate 27; When the lance 11 conveys gas downward, at this time the pneumatic shear 9 will descend synchronously, so that part of the gas will be blocked by the pneumatic shear 9, causing the edge of the mobile phone shell to cool, but the large block of waste of the water gap 4 is not completely cooled, at this time the waste is cut off and falls on the upper surface of the filter plate 27, and then the waste is secondarily cooled by the vibration force of the filter plate 27 and the gas sprayed when the pressure relief groove 34 is relieved, and when the waste is cooled, the waste is turned over by the vibration force of the filter plate 27, thereby promoting the cooling effect of the waste, preventing the waste from adhering to the upper surface of the filter plate 27 due to incomplete cooling, thereby the waste is turned over by the vibration force of the filter plate 27, and the gas sprayed by the pressure relief groove 34 realizes secondary cooling, so that the large block of waste of the water gap 4 is quickly solidified, preventing the waste from adhering to the surface of the filter plate 27 due to high temperature and high viscosity, greatly reducing the frequency and workload of manual cleaning of the filter plate 27, ensuring the cleanliness of the surface of the filter plate 27, and the stable cooling effect can reduce the performance degradation of the waste due to local overheating, improve the reuse value of the recycled material, and reduce the waste of raw materials; When the filter plate 27 transmits the vibration force to the waste, the dust and impurities adhering to the outside of the waste will be removed at the same time, so that the waste has less impurities inside when collected, reducing the subsequent cleaning time.
[0027] In an alternative embodiment, the other end of the separation groove 26 is communicated with a collection groove A 29, and the collection groove A 29 is provided with a collection groove B 30 on one side, and the collection groove B 30 is located in the same vertical plane as the first through groove 20. As the filter plate 27 gradually rises and resets, the waste will gradually slide into the collection groove A 29 under the action of the vibration force and be collected.
[0028] Working principle: when using the device, the cylinder pushes the mold groove B3 to move and contact with the mold groove A2. At this time, the protrusion 36 at the lower end of the mold groove B3 will contact with the inclined block on one side of the limiting plate 21, so that the inclined block will be gradually pressed down with the movement of the protrusion 36. When the inclined block is lowered, the inclined block is fixedly connected with the limiting plate 21, so that the limiting plate 21 will be lowered synchronously when the inclined block is lowered, thereby preventing the limiting plate 21 from blocking the contact between the mold groove B3 and the mold groove A2. After the mold groove B3 and the mold groove A2 are contacted, the raw materials are injected into the mold groove A2 through the water gap 4 on one side of the mold groove A2, so as to plastic the mobile phone shell. After plastic, the mold groove B3 is reset by the cylinder drive; After the mold groove B3 is reset, the extrusion force of the protrusion 36 on the inclined block disappears, and then after the mold groove B3 is reset, the limiting plate 21 will be reset synchronously through the spring A22 at the lower end. After the limiting plate 21 is reset, the end of the limiting plate 21 away from the spring A22 is higher than the bottom of the mold groove A2, so that the limiting plate 21 will limit one end of the injection molded mobile phone shell. After the limiting plate 21 is raised, the third electric push rod 18 will push the push plate 19 outward at this time. After the push plate 19 is pushed outward, the mobile phone shell will only protrude from the end close to the pneumatic clamp 7 when the push plate 19 pushes the mobile phone shell to pop out from the inside of the mold groove A2. At this time, the pneumatic clamp 7 is gradually lowered by the driving of the first electric push rod 6, and the mobile phone shell is clamped and fixed after the pneumatic clamp 7 is lowered to contact the end of the mobile phone shell. After the pneumatic clamp 7 clamps and fixes one end of the mobile phone shell, the second electric push rod 8 will drive the pneumatic shear 9 to descend. When the pneumatic shear 9 is lowered, the pressure rod 17 will be lowered synchronously. When the pressure rod 17 is lowered, the fixed plate 23 will be lowered synchronously. Because the fixed plate 23 is connected with the limiting plate 21, the limiting plate 21 will be lowered synchronously when the fixed plate 23 is lowered, so that the limiting plate 21 is separated from the limiting of the mobile phone shell. After the limiting plate 21 is separated from the limiting of one end of the mobile phone shell, the mobile phone shell will be fixed by the pneumatic clamp 7 in a vertical posture. At this time, with the gradual lowering of the pneumatic shear 9, the grinding plate 10 on one side of the pneumatic shear 9 will contact the side of the mobile phone shell close to the water gap 4, thereby polishing the uneven part of the injection molded side edge of the mobile phone shell. After the pneumatic shear 9 moves to a certain position, the protruding part of the mobile phone shell remaining in the water gap 4 during injection molding will be sheared; When the second electric push rod 8 drives the pneumatic shears 9 to descend, it will drive the connecting rod 16 to descend synchronously, and when the connecting rod 16 descends, it will drive the rack 15 to descend synchronously, and when the rack 15 descends, it will drive the gear 14 to rotate synchronously, and when the gear 14 rotates, it will drive the stop valve inside the air inlet pipe 12 to open through the valve rod 13, after the stop valve is opened, the gas transported by the fan will be transported to the spray gun 11 through the air inlet pipe 12, after the gas is sprayed out of the spray gun 11, the gas will transport cold wind to the clamped and fixed mobile phone shell, and the cold wind will quickly cool the just plastic mobile phone shell when the grinding plate 10 contacts the mobile phone shell, so as to prevent the mobile phone shell from being deformed due to friction when the grinding plate 10 contacts the mobile phone shell because the mobile phone shell is not completely cooled, and at the same time, the wind force transported by the spray gun 11 will exert the falling force on the mobile phone shell when the pneumatic clamp 7 releases the mobile phone shell, so that the mobile phone shell has a certain impact force when it falls through the first through slot 20 to the collecting groove B30, thereby detecting the quality of the mobile phone shell; After the pneumatic shears 9 cut the waste material remaining in the edge of the mobile phone shell inside the water gap 4, the waste material will fall through the second through slot 24 to the inside of the material guide pipe 25, after the waste material enters the inside of the material guide pipe 25, it will be transported by the material guide pipe 25 to the inside of the separation groove 26, after the waste material enters the inside of the separation groove 26, it will fall to the surface of the filter plate 27, because the inclination angle of the filter plate 27 is small, so that when the waste material falls to the upper surface of the filter plate 27, the waste material will not roll down through the inclined angle of the filter plate 27; When the second electric push rod 8 drives the pneumatic shears 9 to reset, the pneumatic shears 9 will reset with the second electric push rod 8, the second electric push rod 8 will drive the rack 15 and the pressure rod 17 to reset at the same time, and then the stop valve inside the air inlet pipe 12 will be closed again when the rack 15 resets. After the stop valve is closed, the gas will form pressure inside the air inlet pipe 12 as the fan continuously transports gas inside the air inlet pipe 12. At this time, the gas will enter the connecting pipe 32 due to the pressure, and the connecting pipe 32 will transport the gas to the guide pipe 31. When the gas gradually increases inside the guide pipe 31, the air pressure will gradually form. When the air pressure gradually increases inside the guide pipe 31, the top rod 33 will be pushed to move outward. When the top rod 33 moves, the filter plate 27 will be lifted to a certain height. After the top rod 33 rises to a certain height, the pressure relief groove 34 will be in contact with the outside world, and then the pressure relief groove 34 will quickly release part of the air pressure inside the guide pipe 31. After the air pressure inside the guide pipe 31 is released, the guide pipe 31 will quickly reset through the gravity of the filter plate 27 and the tension of the spring B35. When the top rod 33 resets, it will quickly drive the filter plate 27 to reset, and then the filter plate 27 will produce knocking vibration force during the process of quickly resetting. The vibration force will be transmitted to the waste on the upper surface of the filter plate 27. When the gas is transported downward by the spray gun 11, the pneumatic shears 9 will descend at the same time, so that part of the gas will be blocked by the pneumatic shears 9, causing the edge of the mobile phone shell to cool down. However, the large block of waste left by the water gap 4 is not completely cooled. At this time, the waste is cut off and falls onto the upper surface of the filter plate 27, and then the waste is cooled again by the vibration force of the filter plate 27 and the gas sprayed when the pressure relief groove 34 is relieved. When the waste is cooled, the waste is turned over by the vibration force of the filter plate 27, thereby improving the cooling effect of the waste.
