Description

Technical Field

[0001] The present invention relates to the technical field of injection molded part processing, and specifically relates to a multi-station processing device for injection molded parts. Background Art

[0002] The multi-station processing of injection molded parts refers to the process of continuously processing or treating products through multiple stations or processes during the injection molding process. This usually includes multiple injection molding machines or additional equipment to complete different processing steps at different stations, such as flash removal, hole processing, assembly, etc., to achieve multi-functional processing and high-efficiency production of products. For example, when performing multi-station processing on tubular injection molded parts, the loading and unloading manipulator drives the male mold and the female mold to close, and then the injection molding machine injects the heated raw material into the mold, so that the product cools and forms in the mold and solidifies into the required injection molded part. Subsequently, the loading and unloading manipulator is used to take out the molded part from the mold of the injection molding machine and place it on the conveyor belt, facilitating the conveyor belt to transport the injection molded part taken out by the unloading manipulator to the next process for processing.

[0003] Existing manipulators all eject the injection molded tubular parts from the female mold and then clamp the tubular injection molded parts. During the process of clamping the injection molded parts of a multi-cavity mold, if the single-jaw clamping method is used, only the injection molded parts of the multi-cavity mold can be clamped one by one, which requires repeated clamping and moving actions, thus significantly increasing the time of each production cycle and reducing the production efficiency. For this reason, existing manipulators mostly use a multi-jaw system for clamping to ensure a relatively fast production efficiency. However, the design of multi-cavity molds usually arranges the cavities closely to achieve the purpose of saving space and materials. This closely arranged cavity also means that the corresponding jaws are arranged closely, which makes the jaws have to operate in a narrow space during the opening and closing process, and it is easy for adjacent jaws to have physical interference. Summary of the Invention

[0004] In order to make up for the deficiencies of the prior art, the present invention proposes a multi-station processing device for injection molded parts. Through the arrangement of the arc plate and the hinge rod, the present invention enables the push rod to push the arc plate to rotate away from the installation cylinder through the hinge rod, so that the outwardly rotating arc plate can support the inner wall of the tubular injection molded part. Compared with a single jaw, a plurality of closely arranged installation cylinders can synchronously take out the injection molded parts in multiple mold cavities, thereby improving the production efficiency. Moreover, compared with the jaw system, the arc plate pushed by the hinge rod is inside the tube of the tubular injection molded part, so physical interference will not occur. Furthermore, while ensuring the normal taking out of the injection molded parts, the safety and service life of the equipment are also ensured, and the practicability of the present invention is improved.

[0017] 2. By setting the suction cup, the present invention enables the arc plate pushed by the telescopic rod to adsorb on the inner wall of the injection molded part through the suction cup. On the one hand, the suction cup made of silicone rubber material has a large friction coefficient, thereby increasing the friction force between the injection molded part and the arc plate. On the other hand, the suction cup is adsorbed on the surface of the injection molded part under extrusion, so that the arc plate can be tightly adsorbed on the inner wall of the injection molded part through the suction cup. Therefore, through the friction force between the arc plate and the injection molded part, it is possible to prevent the injection molded part from sliding off the surface of the arc plate under its own gravity before being transported above the conveyor belt due to its low material friction coefficient or smooth surface. The present invention can stably and firmly take out the smooth injection molded part from the injection mold, effectively improving the actual application effect of the present invention.

[0032] One end of the hinge rod 22 is rotatably connected to the installation cylinder 2; a circular groove 221 is provided at one end of the hinge rod 22 close to the arc-shaped plate 211; a telescopic rod 222 is slidably and sealingly connected inside the circular groove 221; one end of the telescopic rod 222 away from the hinge rod 22 is rotatably connected to the arc-shaped plate 211; the telescopic rod 222 is connected to the bottom of the circular groove 221 through a fixing spring 223.

[0033] The connection unit includes a connecting plate 23; the connecting plate 23 is fixedly connected to the installation cylinder 2; a connecting rod 231 is fixedly connected to the side of the connecting plate 23 away from the arc-shaped plate 211; a groove 232 is provided on the surface of the connecting rod 231; a protrusion 233 is slidably and sealingly connected inside the groove 232; the protrusion 233 is fixedly connected to the bottom of the groove 232 through a connection spring 234; a cylinder 235 is fixedly connected to the side of the electromagnetic plate 17 close to the push rod 18; the connecting rod 231 is slidably connected inside the cylinder 235; a support spring 236 is provided inside the cylinder 235; the support spring 236 is connected to the electromagnetic plate 17.

[0034] One end of the connecting rod 231 away from the cylinder 235 is provided with a pressing groove 24; a pressing plate 241 is slidably and sealingly connected in the pressing groove 24; the pressing groove 24 communicates with the groove 232;

[0035] Existing manipulators eject the injection-molded tubular injection-molded parts from the female mold and then clamp the tubular injection-molded parts. In the process of clamping the injection-molded parts of a multi-cavity mold, if a single jaw clamping method is used, only the injection-molded parts of the multi-cavity mold can be clamped one by one, which requires repeated clamping and moving actions, thus significantly increasing the time of each production cycle and reducing the production efficiency. For this reason, existing manipulators mostly use a multi-jaw system for clamping to ensure a relatively high production efficiency. However, the design of multi-cavity molds usually arranges the cavities closely to achieve the purpose of saving space and materials. This closely arranged cavity also means that the corresponding jaws are arranged closely, which makes the jaws have to operate in a narrow space during the opening and closing process, and it is easy for adjacent jaws to have physical interference, which not only affects the normal removal of the injection-molded parts, but also causes damage and deformation problems between the jaws, thus affecting normal use.

[0036] In the present invention, the gear set 135 includes two meshing gears. One of the gears is connected to the output shaft of the driving motor 134, and the other gear is fixedly connected to the blanking plate 16. The driving motor 134 drives the gear fixedly connected to the blanking plate 16 to rotate through the connected gear, so that the blanking plate 16 rotates under the drive of the fixedly connected gear, and the blanking plate 16 rotates to a state perpendicular to the ground, so as to facilitate the user to install the mounting cylinder 2 on the blanking plate 16. Since the pressing groove 24 is filled with hydraulic oil, when in use, first press the pressing plate 241, so that the pressing plate 241 can squeeze the hydraulic oil in the pressing groove 24 into the groove 232, and the hydraulic oil entering the groove 232 pushes the protrusion 233 to squeeze the connecting spring 234 completely into the groove 232. At this time, the user inserts the connecting rod 231 into the cylinder 235.

[0037] When the connecting rod 231 drives the protrusion 233 into the cylinder 235, release the pressing plate 241, so that the connecting spring 234 pushes the protrusion 233 to extend out of the groove 232 and slide in contact with the inner wall of the cylinder 235 under the action of the restoring force. At this time, the push rod 18 is inserted into the mounting cylinder 2. And through the setting of the pressing plate 241, when the suction cup 21 is damaged due to long-term use, the user only needs to press the pressing plate 241 to quickly remove the mounting cylinder 2 from the electromagnetic plate 17 and replace it, thereby shortening the repair time of the mounting cylinder 2, reducing the equipment downtime, and improving the production efficiency.

[0038] When injection molding of injection molded parts is required, the user only needs to control the transverse guide rail 131 to drive the electric guide rail 132 to drive the feeding plate 15 above the injection mold 12. Then, control the hydraulic push rod 133 to extend, so that the hydraulic push rod 133 can push the blanking plate 16 down, so that the blanking plate 16 can contact the upper mold of the injection mold 12, so that the blanking plate 16 pushes the upper mold to abut against the lower mold. Then, control the injection molding machine 14 to inject raw materials into the injection mold 12 through the injection pipeline, and then control the feeding plate 15 to rise;

[0039] At this time, the rotating platform 11 rotates and drives the next injection mold 12 to rotate in the direction of the feeding plate 15. After the next injection mold 12 rotates to the position of the feeding plate 15, control the feeding plate 15 to descend and inject again; when the injection mold 12 filled with raw materials rotates to the position of the feeding plate 15, at this time, the raw materials in the injection mold 12 cool and solidify. Control the feeding plate 15 to descend and contact the upper mold of the injection mold 12, and control the electromagnetic plate 17 of the feeding plate 15 to operate, so that the electromagnetic plate 17 adsorbs the upper end face of the upper mold. Control the hydraulic push rod 133 to rise, so that the hydraulic push rod 133 can pull the upper mold to rise, and control the transverse guide rail 131 to drive the feeding plate 15 to move to one side;

[0040] And the blanking plate 16 moves above the injection mold 12. At this time, control the hydraulic push rod 133 to descend, and by controlling the driving motor 134 to drive the gear set 135 to rotate, so that the blanking plate 16 drives the installed mounting cylinder 2 to move vertically downward. At this time, the cavity in the injection mold 12 is aligned with the mounting cylinder 2 of the blanking plate 16. Control the hydraulic push rod 133 to descend, so that the hydraulic push rod 133 can push the blanking plate 16 down, so that the blanking plate 16 can drive the mounting cylinder 2 into the core of the tubular injection molded part in the cavity. Then, control the electromagnetic plate 17 to operate, so that the electromagnetic plate 17 can generate a magnetic adsorption force on the connecting rod 231, so that the connecting rod 231 enters the cylinder 235 under the adsorption of the magnetic adsorption force, so that the connecting rod 231 compresses the support spring 236 in the cylinder 235 through the protrusion 233;

[0041] At this time, the connecting rod 231 drives the mounting cylinder 2 closer to the electromagnetic plate 17 through the connecting plate 23, causing the push rod 18 to move relative to the mounting cylinder 2 in the direction closer to the hinge rod 22, so that the push rod 18 can push the hinge rod 22 to rotate; since the hinge rod 22 and the arc-shaped plate 211 are rotatably connected by a torsion spring, the hinge rod 22 drives the arc-shaped plate 211 to rotate synchronously. During the rotation of the arc-shaped plate 211 at this time, the end of the arc-shaped plate 211 away from the mounting cylinder 2 will contact the inner wall of the tubular injection molding. As a result, the arc-shaped plate 211 rotates against the torsion force of the torsion spring under the block of the inner wall of the tubular injection molding, so that the arc-shaped plate 211 is parallel and attached to the inner wall of the tubular injection molding. At this time, as the hinge rod 22 continues to rotate, the hinge rod 22 drives the telescopic rod 222 to rotate, so that the telescopic rod 222 is blocked by the arc-shaped plate 211 and squeezes the fixed spring 223 in the circular groove 221 into the interior of the circular groove 221 until the hinge rod 22 is in a horizontal state under the push of the push rod 18. At this time, the push rod 18 is in sliding contact with the hinge rod 22;

[0042] Due to the restoring force of the support spring 236 acting on the telescopic rod 222, the telescopic rod 222 pushes the arc-shaped plate 211 against the inner wall of the injection molding. At this time, the hydraulic push rod 133 is controlled to contract, so that the hydraulic push rod 133 pulls the injection molding in the mold cavity upward through the mounting cylinder 2 and the arc-shaped plate 211. Subsequently, the blanking plate 16 moves toward the conveyor belt on the side away from the feeding plate 15. When it moves above the conveyor belt, the electromagnetic plate 17 is controlled to be powered off. At this time, the connecting plate 23 extends out of the cylinder 235 under the push of the support spring 236, so that the push rod 18 enters the mounting cylinder 2. At this time, the push rod 18 no longer exerts a pushing force on the hinge rod 22. And because the hinge rod 22 and the mounting cylinder 2 are rotatably connected by a torsion spring, the hinge rod 22 rotates reversely under the action of the restoring force of the torsion spring, so that the reversely rotating hinge rod 22 can drive the telescopic rod 222 to rotate, and the telescopic rod 222 rotates relative to the arc-shaped plate 211 until the telescopic rod 222 completely extends out of the circular groove 221 and no longer exerts a pushing force on the arc-shaped plate 211. At this time, the arc-shaped plate 211 moves away from the inner wall of the injection molding under the drive of the telescopic rod 222, so that the arc-shaped plate 211 no longer contacts the injection molding, and the injection molding falls onto the conveyor belt;

[0043] At this time, the loading plate 15 drives the upper mold above the injection mold 12, so that the loading plate 15 presses the upper mold against the lower mold, and the injection molding machine 14 is controlled for injection molding; and by setting the suction cup 21, the arc plate 211 pushed by the telescopic rod 222 can adsorb on the inner wall of the injection molded part through the suction cup 21. On the one hand, the suction cup 21 made of silicone rubber material has a large friction coefficient, so as to improve the friction force between the injection molded part and the arc plate 211. On the other hand, the suction cup 21 is squeezed and adsorbed on the surface of the injection molded part, so that the arc plate 211 can be tightly adsorbed on the inner wall of the injection molded part through the suction cup 21. Thus, through the friction force between the arc plate 211 and the injection molded parts, it is avoided that before the injection molded part blanking plate 16 is transported above the conveyor belt, it slides off the surface of the arc plate 211 under its own gravity due to the low friction coefficient of its material (such as an injection molded part made of PTFE material) or a smooth surface, so that the present invention can stably and firmly take out the smooth injection molded part from the injection mold 12, effectively improving the actual application effect of the present invention;

[0044] Therefore, through the arrangement of the arc plate 211 and the hinge rod 22 in the present invention, the push rod 18 pushes the arc plate 211 to rotate away from the mounting cylinder 2 through the hinge rod 22, so that the outwardly rotating arc plate 211 can support the inner wall of the cylindrical injection molded part. Compared with a single jaw, a plurality of closely arranged mounting cylinders 2 can synchronously take out the injection molded parts in a plurality of mold cavities, thus improving the production efficiency. Moreover, compared with the jaw system, the arc plate 211 pushed by the hinge rod 22 is inside the cylinder of the cylindrical injection molded part, so physical interference will not occur. Therefore, while ensuring the normal taking out of the injection molded parts, the safety and service life of the equipment are also ensured, improving the practicability of the present invention.

[0045] As an implementation manner of the present invention, an air storage cavity 25 is provided in the mounting cylinder 2; a sealing plate 251 is slidably and sealingly connected in the air storage cavity 25; the sealing plate 251 is connected to the hinge rod 22 through a connecting pipe 252; one end of the telescopic rod 222 close to the arc plate 211 is connected to the suction cup 21 through an air pipe; the end of the air pipe far from the suction cup 21 is communicated with the circular groove 221; one end of the connecting pipe 252 is communicated with the air storage cavity 25, and the other end is communicated with the circular groove 221; the sealing plate 251 is connected to the bottom of the air storage cavity 25 through a return spring 253.

[0046] A through groove 26 is provided on the surface of the sealing plate 251; the connecting pipe 252 is connected to the through groove 26; a shielding rod 261 is slidably and sealingly connected inside the through groove 26; an L-shaped groove 262 communicated with the through groove 26 is provided on the surface of the shielding rod 261; the shielding rod 261 is connected to the bottom of the air storage cavity 25 through a steel wire rope 263.

[0047] An exhaust port 264 communicating with the L-shaped groove 262 is formed at the lower end of the shielding rod 261; a check valve 265 is fixedly installed in the exhaust port 264; an air inlet 27 communicating with the air storage cavity 25 is formed in the side wall of the mounting cylinder 2; a solenoid valve 271 is installed in the air inlet 27;

[0048] Specifically, the suction cup 21 and the telescopic rod 222 are connected by a trachea. One end of the trachea connected to the telescopic rod 222 penetrates through the telescopic rod 222 and communicates with the circular groove 221; the connecting pipe 252 is a thin pipe made of fiberglass material, which enables the connecting rod 231 to have good corrosion resistance, wear resistance, strength and hardness like a fiberglass pipe, and has a good bending effect, and the cost is relatively low;

[0049] During the process of the push rod 18 pushing the hinge rod 22 to rotate, the hinge rod 22 can rise through the connecting pipe 252 and stretch the return spring 253 through the sealing plate 251 in the air storage cavity 25, so that the distance between the sealing plate 251 and the bottom of the air storage cavity 25 increases, thereby making the air storage cavity 25 in a negative pressure state; at this time, during the process of the sealing plate 251 sliding in the air storage cavity 25, the sealing plate 251 will drive the shielding rod 261 slidably connected to it to move synchronously, so that the shielding rod 261 stretches the steel wire rope 263 to extend;

[0050] When the hinge rod 22 rotates to the horizontal state, at this time the distance between the sealing plate 251 and the bottom of the air storage cavity 25 is the largest, that is, the negative pressure at this time is the largest, and at this time the steel wire rope 263 is straightened, so that the shielding rod 261 drives the L-shaped groove 262 on its surface to move towards the end close to the steel wire rope 263 of the through groove 26, so that the gas in the suction cup 21 and the circular groove 221 enters the air storage cavity 25 through the connecting rod 231 and the trachea. At this time, the suction cup 21 is in a negative pressure state, so that the suction cup 21 can tightly adsorb the inner wall of the injection molded part, thereby improving the adsorption force of the suction cup 21 on the injection molded part;

[0051] After the electromagnetic plate 17 is powered off, the mounting cylinder 2 is pushed away from the electromagnetic plate 17 by the support spring 236, so that the articulated rod 22 is no longer pushed by the push rod 18 and drives the arc plate 211 away from the injection molded part under the action of the restoring force of the torsion spring; at this time, the articulated rod 22 no longer pulls the sealing plate 251 through the connecting pipe 252, so that the sealing plate 251 pulls the suction cup 21 close to the bottom of the air storage cavity 25 under the restoring force of the reset spring 253, causing the air pressure in the air storage cavity 25 to rise. And the gas in the air storage cavity 25 enters the through groove 26 through the L-shaped groove 262 and the exhaust port 264 under the closed push, and enters the circular groove 221 and the suction cup 21 through the connecting pipe 252 communicated with the through groove 26. Since the telescopic rod 222 in the circular groove 221 extends out of the circular groove 221, the space in the circular groove 221 increases. To ensure that the circular groove 221 is not in a negative pressure state and prevent the suction cup 21 from still having too strong an adsorption force on the injection molded part, making it difficult for the injection molded part to separate from the suction cup 21;

[0052] In the present invention, by providing the air inlet 27 and controlling the solenoid valve 271 to open, the outside gas enters the air storage cavity 25 through the air inlet 27, so that the air cavity entering the air storage cavity 25 can enter the connecting pipe 252 through the L-shaped groove 262 and the exhaust port 264, and is filled into the circular groove 221 and the suction cup 21 by the connecting pipe 252, so that the suction cup 21 is inflated and no longer adsorbs the injection molded part;

[0053] When adsorbing an injection molded part with a larger barrel diameter, since the elongation of the telescopic rod 222 is small and there is more air in the circular groove 221, more air in the circular groove 221 will flow into the air storage cavity 25. If there is still more air remaining in the air storage cavity 25, it will cause a smaller negative pressure in the air storage cavity 25, thereby affecting the adsorption effect of the suction cup 21. Therefore, through the setting of the exhaust port 264, when the reset spring 253 pulls the shielding rod 261 to contact the bottom of the air storage cavity 25 through the sealing plate 251, the shielding rod 261 drives the L-shaped groove 262 on its surface into the through groove 26 under the block of the bottom of the air storage cavity 25. At this time, the gas in the air storage cavity 25 can flow into the connecting pipe 252 through the exhaust port 264, further increasing the air discharge amount in the air storage cavity 25. After the solenoid valve 271 is closed, the air residue in the air storage cavity 25 is reduced, thereby ensuring an increase in the air pressure adsorption force in the air storage cavity 25, improving the adsorption effect of the suction cup 21 on the inner wall of the injection molded part, enabling the present invention to stably and firmly take out the injection molded part, and further improving the actual application effect of the present invention.
