Description

Technical Field

[0001] The invention relates to the technical field of injection molding processing, in particular to a multi-station processing device for injection molding parts. Background Art

[0002] Multi-station processing of injection molded parts refers to the process of continuously processing or handling 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 efficient production of products; for example, when multi-station processing is performed on tubular injection molded parts; the loading and unloading manipulator drives the punch and the die to close, and then the injection molding machine injects the heated raw materials into the mold, so that the product is cooled and formed in the mold, and solidified into the required injection molded parts; then the loading and unloading manipulator is used to take the molded parts out of the mold of the injection molding machine and place them on the conveyor belt, so that the conveyor belt can transport the injection molded parts taken out by the unloading manipulator to the next process for processing; Existing robots eject the molded tubular injection molded parts from the die and then clamp the tubular injection molded parts. In the process of clamping the injection molded parts of the multi-cavity mold, if a single clamping jaw is used, the injection molded parts of the multi-cavity mold can only be clamped one by one, which requires repeated clamping and moving actions, thereby significantly increasing the time of each production cycle and reducing production efficiency. For this reason, existing robots mostly use a multi-jaw system for clamping to ensure faster production efficiency. However, the design of the multi-cavity mold usually designs the cavities to be closely arranged to save space and materials. This closely arranged cavity also means that the correspondingly closely arranged jaws make it necessary for the jaws to operate in a small space during the opening and closing process, which easily causes physical interference between adjacent jaws. Summary of the invention

Compared with a single clamp, a plurality of closely arranged mounting cylinders can synchronously take out the injection molded parts in a plurality of mold cavities, thereby improving production efficiency. Moreover, compared with the clamp system, the arc plate pushed by the hinged rod is in the cylinder of the cylindrical injection molded part, so that no physical interference will occur. Therefore, while ensuring the normal removal of the injection molded parts, the safety and service life of the equipment are also guaranteed, thereby improving the practicality of the present invention.

The friction between the arc plate and the injection molded part can prevent the injection molded part blanking plate from sliding off the surface of the arc plate under the action of its own gravity before being transported to the top of the conveyor belt due to its low material friction coefficient or smooth surface.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0017] like Figures 1 to 7 As shown, the multi-station processing equipment for injection molded parts of the present invention comprises: A workbench 1, and an injection mold 12 mounted on the upper end of the workbench 1 through a rotating platform 11; a mounting frame 13 is arranged above the injection mold 12; an injection molding machine 14 is installed on the upper end of the mounting frame 13; the injection molding machine 14 is used to inject raw materials into the injection mold 12; a transverse guide rail 131 is arranged on one side of the mounting frame 13; two mutually parallel electric guide rails 132 are slidably mounted on the upper end of the transverse guide rail 131; a hydraulic push rod 133 is slidably mounted on the upper end of the electric guide rail 132; A driving motor 134 is installed on the side wall of the hydraulic push rod 133; a loading plate 15 and a loading plate 16 are respectively arranged below the two electric guide rails 132; the loading plate 15 and the loading plate 16 are both rotatably installed on the lower end of the hydraulic push rod 133 through a gear set 135; the driving motor 134 is used to drive the gear set 135 to rotate; an electromagnetic plate 17 is fixedly installed on one side of the loading plate 15 and the loading plate 16; a side of the electromagnetic plate 17 away from the loading plate 16 is fixedly connected to a pushing rod 18; a mounting tube 2 is sleeved on the surface of the pushing rod 18; a suction cup 21 is installed on the surface of the mounting tube 2.

[0018] An arc plate 211 is provided at one end of the mounting tube 2 away from the pushing rod 18; the suction cup 21 is installed on the arc plate 211; the arc plate 211 and the mounting tube 2 are connected via a hinge rod 22; a connecting unit is installed in the mounting tube 2; the connecting unit is used to connect the mounting tube 2 with the pushing rod 18.

[0019] One end of the hinged rod 22 is rotatably connected to the mounting tube 2; a circular groove 221 is provided at one end of the hinged rod 22 close to the arc plate 211; a telescopic rod 222 is connected to the sliding seal in the circular groove 221; one end of the telescopic rod 222 away from the hinged rod 22 is rotatably connected to the arc plate 211; the telescopic rod 222 is connected to the bottom of the circular groove 221 via a fixed spring 223.

[0020] The connecting unit includes a connecting plate 23; the connecting plate 23 is fixedly connected to the mounting cylinder 2; the side of the connecting plate 23 away from the arc plate 211 is fixedly connected to the connecting rod 231; a groove 232 is provided on the surface of the connecting rod 231; a protrusion 233 is slidingly sealed in the groove 232; the protrusion 233 is fixedly connected to the bottom of the groove 232 by a connecting spring 234; the side of the electromagnetic plate 17 close to the push rod 18 is fixedly connected to the cylinder 235; the connecting rod 231 is slidably connected in the cylinder 235; a support spring 236 is arranged inside the cylinder 235; the support spring 236 is connected to the electromagnetic plate 17.

[0021] A pressing groove 24 is formed at one end of the connecting rod 231 away from the cylinder 235; a pressing plate 241 is slidably and sealably connected in the pressing groove 24; and the pressing groove 24 is communicated with the groove 232; Existing manipulators eject the molded tubular injection molded parts from the die and then clamp the tubular injection molded parts. In the process of clamping the injection molded parts of the multi-cavity mold, if a single clamping jaw is used, the injection molded parts of the multi-cavity mold can only be clamped one by one, which requires repeated clamping and moving actions, thereby significantly increasing the time of each production cycle and reducing production efficiency. For this reason, existing manipulators mostly use a multi-claw system for clamping to ensure faster production efficiency. However, the design of the multi-cavity mold usually designs the cavities to be closely arranged. In order to save space and materials, this closely arranged cavity also means that the corresponding arrangement of the clamps is closely arranged, which requires the clamps to operate in a small space during the opening and closing process, which is easy to cause physical interference between adjacent clamps, not only affecting the normal removal of the injection molded parts, but also causing damage and deformation between the clamps, thereby affecting normal use. In the present invention, the gear set 135 includes two gears meshing with each other, one of which is connected to the output shaft of the driving motor 134, and the other 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 gear connected thereto, so that the blanking plate 16 rotates under the drive of the fixedly connected gear, so that the blanking plate 16 rotates to a state vertical to the ground, so that the user can install the mounting cylinder 2 on the blanking plate 16; since the pressing groove 24 is filled with hydraulic oil, the pressing plate 241 is pressed first during use, so that the pressing plate 241 can squeeze the hydraulic oil in the pressing groove 24 into the groove 232, so that the hydraulic oil entering the groove 232 pushes the protrusion 233 to squeeze the connecting spring 234 to completely enter the groove 232; at this time, the user inserts the connecting rod 231 into the cylinder 235; When the connecting rod 231 drives the protrusion 233 to enter the cylinder 235, the pressing plate 241 is released, so that the connecting spring 234, under the action of the restoring force, pushes the protrusion 233 out of the groove 232 and slides into contact with the inner wall of the cylinder 235, and the pushing rod 18 is inserted into the installation 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 installation cylinder 2 from the electromagnetic plate 17 and replace it, thereby shortening the repair time of the installation cylinder 2, reducing the equipment downtime, and improving production efficiency; When the injection molding process is required, the user only needs to control the transverse guide rail 131 to drive the electric guide rail 132 to drive the loading plate 15 to the top of the injection mold 12, and then control the hydraulic push rod 133 to extend, so that the hydraulic push rod 133 can push the unloading plate 16 down, so that the unloading plate 16 can contact the upper mold of the injection mold 12, so that the unloading plate 16 pushes the upper mold and the lower mold to be pressed tightly, and then control the injection molding machine 14 to inject the raw material into the injection mold 12 through the injection pipe, and then control the loading plate 15 to rise; At this time, the rotating platform 11 rotates and drives the next injection mold 12 to rotate in the direction of the loading plate 15, so that after the next injection mold 12 rotates to the loading plate 15, the loading plate 15 is controlled to descend and injection molding is performed again; when the first injection mold 12 filled with raw materials rotates to the loading plate 15, the raw materials in the injection mold 12 are cooled and solidified, and the loading plate 15 is controlled to descend to contact the upper mold of the injection mold 12 and the electromagnetic plate 17 of the loading plate 15 is controlled to operate so that the electromagnetic plate 17 adsorbs the upper end surface of the upper mold, and the hydraulic push rod 133 is controlled to rise, so that the hydraulic push rod 133 can pull the upper mold to rise, and the transverse guide rail 131 is controlled to drive the loading plate 15 to move to one side; The blanking plate 16 moves to the top of the injection mold 12, and at this time, the hydraulic push rod 133 is controlled to descend, and the driving motor 134 is controlled to drive the gear set 135 to rotate, so that the blanking plate 16 drives the installed installation cylinder 2 to move vertically downward. At this time, the mold cavity in the injection mold 12 is directly opposite to the installation cylinder 2 of the blanking plate 16, and the hydraulic push rod 133 is controlled to descend, so that the hydraulic push rod 133 can push the blanking plate 16 to descend, so that the blanking plate 16 can drive the installation cylinder 2 to enter the cylinder core of the cylindrical injection molded part in the mold cavity, and then the electromagnetic plate 17 is controlled 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 supporting spring 236 in the cylinder 235 through the protrusion 233; At this time, the connecting rod 231 drives the installation cylinder 2 to approach the electromagnetic plate 17 through the connecting plate 23, so that the push rod 18 moves relative to the installation cylinder 2 in the direction close to the hinge rod 22, so that the push rod 18 can push the hinge rod 22 to rotate; because the hinge rod 22 is rotatably connected with the arc plate 211 through the torsion spring, the hinge rod 22 drives the arc plate 211 to rotate synchronously. At this time, during the rotation process of the arc plate 211, the end of the arc plate 211 away from the installation cylinder 2 will contact the inner wall of the cylindrical injection molded part, so that the arc plate 2 11 is blocked by the inner wall of the cylindrical injection molded part and overcomes the torsion of the torsion spring to rotate, so that the arc plate 211 is parallel to the inner wall of the cylindrical injection molded part, and 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 can be blocked by the arc plate 211 and squeeze the fixed spring 223 in the circular groove 221 into the circular groove 221, until the hinge rod 22 is in a horizontal state under the push of the push rod 18, and at this time, the push rod 18 is in sliding contact with the hinge rod 22; Since the telescopic rod 222 is acted upon by the restoring force of the supporting spring 236, the telescopic rod 222 pushes the arc plate 211 to press against the inner wall of the injection molded part. At this time, the hydraulic push rod 133 is controlled to contract, so that the hydraulic push rod 133 pulls the injection molded part in the mold cavity to rise through the mounting cylinder 2 and the arc plate 211. Subsequently, the unloading plate 16 moves toward the conveyor belt on the side away from the loading plate 15. When it moves to the top of 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 supporting spring 236, so that the pushing rod 18 enters the mounting cylinder 2. At this time, the pushing rod 18 no longer presses against the The hinge rod 22 generates a pushing effect, and because the hinge rod 22 and the mounting tube 2 are rotationally connected via a torsion spring, the hinge rod 22 is rotated in the opposite direction under the action of the torsion spring restoring force, so that the hinge rod 22 rotating in the opposite direction can drive the telescopic rod 222 to rotate, so that the telescopic rod 222 rotates relative to the arc plate 211, until the telescopic rod 222 is completely extended out of the circular groove 221 and no longer generates a pushing force on the arc plate 211, the arc plate 211 is driven by the telescopic rod 222 to move away from the inner wall of the injection molded part, so that the arc plate 211 is no longer in contact with the injection molded part, so that the injection molded part falls onto the conveyor belt; At this time, the loading plate 15 drives the upper mold to the top of the injection mold 12, so that the loading plate 15 presses the upper mold against the lower mold, and controls the injection molding machine 14 to perform injection molding; and by providing the suction cup 21, the arc plate 211 pushed by the telescopic rod 222 can be adsorbed 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, thereby increasing the friction 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, so that the friction between the arc plate 211 and the injection molded part can be prevented from sliding off the surface of the arc plate 211 under the action of its own gravity before being transported to the top of the conveyor belt due to its low material friction coefficient (such as the injection molded part made of PTFE material) or smooth surface. This allows the present invention to stably and firmly remove the smooth injection molded part from the injection mold 12, so that the practical application effect of the present invention is effectively improved; Therefore, the present invention arranges the arc plate 211 and the hinged rod 22 so that the push rod 18 pushes the arc plate 211 to rotate away from the mounting tube 2 through the hinged rod 22, so that the arc plate 211 rotating outward can support the inner wall of the cylindrical injection molded part. Compared with a single clamp, a plurality of closely arranged mounting tubes 2 can synchronously remove the injection molded parts in a plurality of mold cavities, thereby improving production efficiency. Moreover, compared with the clamp system, the arc plate 211 pushed by the hinged rod 22 is inside the tube of the cylindrical injection molded part, so that no physical interference will occur. Therefore, while ensuring the normal removal of the injection molded parts, the safety and service life of the equipment are also guaranteed, thereby improving the practicality of the present invention.

[0022] As an embodiment of the present invention, an air storage chamber 25 is opened in the mounting tube 2; a sealing plate 251 is slidingly and sealingly connected in the air storage chamber 25; the sealing plate 251 is connected to the hinged rod 22 via a connecting pipe 252; the end of the telescopic rod 222 close to the arc plate 211 is connected to the suction cup 21 via an air pipe; the end of the air pipe away from the suction cup 21 is connected to the circular groove 221; one end of the connecting pipe 252 is connected to the air storage chamber 25, and the other end is connected to the circular groove 221; the sealing plate 251 is connected to the bottom of the air storage chamber 25 via a reset spring 253.

[0023] 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 sliding seal is provided inside the through groove 26 and is connected to a shielding rod 261; an L-shaped groove 262 connected to 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 chamber 25 by a steel wire rope 263.

[0024] The lower end of the shielding rod 261 is provided with an exhaust port 264 connected to the L-shaped groove 262; a one-way valve 265 is fixedly installed in the exhaust port 264; the side wall of the installation tube 2 is provided with an air inlet 27 connected to the air storage chamber 25; a solenoid valve 271 is installed in the air inlet 27; Specifically, the suction cup 21 is connected to the telescopic rod 222 through an air pipe, and one end of the air pipe connected to the telescopic rod 222 passes through the telescopic rod 222 and is connected to the circular groove 221; the connecting tube 252 is a thin tube made of glass fiber material, which makes the connecting rod 231 have good corrosion resistance, wear resistance, strength and hardness like a glass fiber tube, as well as good bending effect, and the cost is relatively low; When the push rod 18 pushes the hinge rod 22 to rotate, the hinge rod 22 can rise through the sealing plate 251 in the air storage chamber 25 through the connecting tube 252 and stretch the reset spring 253, so that the distance between the sealing plate 251 and the bottom of the air storage chamber 25 increases, so that the air storage chamber 25 is in a negative pressure state; at this time, when the sealing plate 251 slides in the air storage chamber 25, the sealing plate 251 will drive the shielding rod 261 slidably connected thereto to move synchronously, so that the shielding rod 261 stretches the steel wire rope 263; When the hinged rod 22 rotates to a horizontal state, the distance between the sealing plate 251 and the bottom of the air storage chamber 25 is the largest, that is, the negative pressure is the largest, and the wire rope 263 is straightened, so that the shielding rod 261 drives the L-shaped groove 262 on the surface to extend out of the through groove 26 close to the end of the wire rope 263 under the pulling force of the wire rope 263, so that the gas in the suction cup 21 and the circular groove 221 enters the air storage chamber 25 through the connecting rod 231 and the air pipe. 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; 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 hinge 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 torsion spring restoring force; at this time, the hinge rod 22 no longer pulls the sealing plate 251 through the connecting tube 252, so that the sealing plate 251 is pulled close to the bottom of the air storage chamber 25 by the restoring force of the return spring 253, so that the air pressure in the air storage chamber 25 rises , and the gas in the gas storage chamber 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 connected 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 is increased. In order to ensure that the circular groove 221 is not in a negative pressure state, it is prevented that the suction cup 21 still has too strong adsorption force on the injection molded part, which makes it difficult to separate the injection molded part from the suction cup 21; The present invention provides an air inlet 27 and controls the electromagnetic valve 271 to open, so that external air enters the air storage chamber 25 through the air inlet 27, so that the air in the air storage chamber 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; When adsorbing an injection molded part with a larger cylinder diameter, the telescopic rod 222 has a smaller extension amount, and the circular groove 221 has a larger air content, so that more air in the circular groove 221 will flow into the air storage chamber 25. If there is still more air remaining in the air storage chamber 25, it will cause a smaller negative pressure in the air storage chamber 25, thereby affecting the adsorption effect of the suction cup 21. Therefore, by setting the exhaust port 264, when the return spring 253 pulls the shielding rod 261 through the sealing plate 251 to contact the bottom of the air storage chamber 25, the shielding rod 261 is in the air storage chamber 25. The L-shaped groove 262 on its surface is driven to enter the through groove 26 under the obstruction of the bottom. At this time, the gas in the air storage chamber 25 can flow into the connecting pipe 252 through the exhaust port 264, further increasing the discharge amount of air in the air storage chamber 25, so that after the solenoid valve 271 is closed, the residual air in the air storage chamber 25 is reduced, thereby ensuring that the air pressure adsorption force in the air storage chamber 25 is increased, improving the adsorption effect of the suction cup 21 on the inner wall of the injection molded part, so that the present invention can stably and firmly take out the injection molded part, so that the practical application effect of the present invention is further improved.
