Description

Technical Field

[0001] The invention belongs to the technical field of electric equipment processing, in particular to a device for manufacturing an electric equipment shell and a manufacturing method thereof. Background Art

[0002] The casing of electrical equipment is usually made of plastic, such as motor casing, generator casing, capacitor casing, etc. It has the advantages of light weight, low cost, corrosion resistance, etc. During processing, it is directly formed by injection molding. Injection molding is a method of producing industrial products. Thermoplastic plastics or thermosetting materials are made into plastic products of various shapes using plastic molding molds through injection molding machines.

[0003] A Chinese patent with publication number CN118977365A discloses a shell injection molding device for processing electrical plastics and shells, including a base plate, an injection molding component is arranged on the top of the base plate, and a lifting mechanism is arranged on the injection molding component; an injection molding cavity is formed by using an upper mold base and a lower mold base, and an injection molding machine and an injection molding gun are used for injection molding. After the injection molding is completed, the rack is driven to move by rotating the gear, and the rack drives the push plate to slide along the inner wall of the slide cylinder and push the bottom block, so that the bottom block drives the connecting rod to move, and the connecting rod drives the top block to move, so that the top block pushes out the finished product after injection molding and cooling; the connecting plate and the sliding sleeve are pulled by the articulated arm to slide along the outer wall of the slide rod, so that the connecting plate drives the push rack to move, so that the push rack pushes the plastic shell ejected from the lower mold base outward and makes it fall onto the guide inclined plate, which is convenient for the rapid unloading of the plastic shell.

[0004] In the above technology, the finished product can be quickly pushed out through the lifting mechanism, and then output through the guide ramp, but the whole process does not provide buffering and protection for the finished product. At this time, if the slope of the guide ramp is large, it will slide directly and easily cause the finished product to be damaged under the action of external force; if the slope of the guide ramp is small, the impact force is reduced, thereby reducing the influence of external force on the outer shell, but the outer shell is light in weight and has a certain friction with the guide ramp, resulting in uneven discharge and reduced discharge speed.

[0005] To this end, the present invention provides an electrical equipment housing manufacturing device and a manufacturing method thereof. Summary of the invention

[0052] When the discharging unit provided by the present invention is used, it is first necessary to push out the formed shell, and when the bottom of the shell is higher than the surface of the workbench 1, stop moving, and then turn on the third motor 57, and drive the bidirectional ball screw 55 to rotate through the output shaft of the third motor 57, and drive the moving plate 5 to move in the opposite direction through the bidirectional ball screw 55, and drive the clamping plate 58 to move in the opposite direction through the moving plate 5, until the clamping plate 58 clamps the shell, and then turn on the second electric push rod 53, and the second electric push rod 53 drives the moving frame 51 to move through the output end, and then The movable frame 51 drives the movable plate 5 and the shell to move, and the movable frame 51 moves to one end of the sliding opening 11 and contacts the touch switch 12. At the same time, the third motor 57 controls the movable plate 5 to move in the opposite direction, and the movable plate 5 drives the clamping plate 58 to move in the opposite direction. The clamping plate 58 opens, and the shell falls on the conveyor belt 6. Under the action of the touch switch 12, the driving motor is turned on, and the conveyor belt 6 is driven by the driving motor to rotate, and the shell is conveyed by the conveyor belt 6, thereby completing the unloading; by setting the rubber pad 52, the clamping plate 58 is placed to clamp the surface of the shell;

[0053] During the conveying process, the infrared scanner 65 is used to scan the defects of the shell. If the infrared scanner 65 detects an abnormality, the computer system controls the third electric push rod 64 to open, and the third electric push rod 64 drives the push plate 63 to move through the output end, and the push plate 63 pushes the shell to the discharge port 61, and then it needs to be melted and injected again; if the monitoring is normal, it can continue to be transported to the next process by the conveyor belt 6.

[0054] like Figure 2 As shown in the figure, the injection molding unit includes an outer cylinder 2, an inner cylinder 21 and a filter basket 24; a plurality of heating tubes 27 are fixedly connected and arranged circumferentially between the outer cylinder 2 and the inner cylinder 21; a cover plate 22 is inserted at the top of the inner cylinder 21; a liquid inlet pipe 23 is fixedly connected to the top of the cover plate 22; a filter basket 24 is fixedly connected to the bottom of the cover plate 22, a spring 26 is fixedly connected to the inner wall of the bottom of the filter basket 24, a scraper 25 is fixedly connected to the top of the spring 26, and the scraper 25 is slidably connected to the inner wall of the filter basket 24.

[0055] When the outer cylinder 2, the inner cylinder 21 and the filter basket 24 provided by the present invention are in use, the molten injection liquid is injected into the inner cylinder 21 through the liquid inlet pipe 23, and passes through the filter basket 24 during the injection process. The filter basket 24 filters impurities in the injection liquid to prevent impurities from causing bubbles in the outer shell and poor outer shell quality during injection. The filter basket 24 is clogged with impurities after a period of time, affecting the speed of infusion. Therefore, a spring 26 and a scraper 25 are provided. During infusion, under the action of the spring 26, the scraper 25 slides up and down to scrape the impurities on the inner wall of the filter basket 24 to maintain the flow rate of the infusion. The heating tube 27 is provided to maintain the temperature of the injection liquid in the inner cylinder 21 to prevent cooling and solidification.

[0056] like Figure 6 As shown, the injection unit also includes an upper mold 34 and a lower mold 4, the top of the upper mold 34 is fixedly connected to a lifting plate 32; the top of the workbench 1 is fixedly connected to a first fixed frame 3, the top of the first fixed frame 3 is fixedly connected to a cylinder 31, and the output end of the cylinder 31 is fixedly connected to the top of the lifting plate 32; the top of the workbench 1 is fixedly connected to four sliding columns 33, and the four corners of the lifting plate 32 are slidably connected to the sliding columns 33 respectively.

[0057] When the upper mold 34 provided by the present invention is in use, the cylinder 31 is turned on, the lifting plate 32 is driven to move through the output end of the cylinder 31, and the upper mold 34 is driven to move through the lifting plate 32. The upper mold 34 cooperates with the lower mold 4 to form a mold cavity, which is convenient for injection molding of the injection liquid in the mold cavity; during the movement of the lifting plate 32, the lifting plate 32 slides on the sliding column 33, and the sliding column 33 limits the lifting plate 32 in the vertical direction.

[0058] like Figure 2As shown, the lower mold 4 is fixedly connected to the workbench 1 and cooperates with the upper mold 34; a work box 41 is fixedly connected to the bottom of the workbench 1; a liquid outlet pipe 28 is connected and fixedly connected to the lower mold 4, one end of the liquid outlet pipe 28 is connected and fixedly connected to the bottom of the inner cylinder 21, and is connected and fixedly connected to the side wall of the lower mold 4; a solenoid valve 29 is installed on the liquid outlet pipe 28.

[0059] The liquid outlet pipe 28 provided by the present invention is used to transport injection liquid when in use. When injection molding is required, the injection liquid in the inner cylinder 21 is transported to the mold cavity through the liquid outlet pipe 28 by opening the solenoid valve 29 for injection molding.

[0060] like Figure 3 and Figure 8 As shown, two first electric push rods 42 are fixedly connected to the bottom of the lower mold 4, and the output ends of the first electric push rods 42 pass through the bottom of the working box 41 and are fixedly connected to a connecting plate 44. Both ends of the connecting plate 44 are fixedly connected to a push rod 43, and the push rod 43 passes through the four corners of the bottom of the lower mold 4.

[0061] When the push rod 43 provided by the present invention is in use, the loosened outer shell is hammered to discharge the material, and the first electric push rod 42 is turned on, and the output end of the first electric push rod 42 drives the connecting plate 44 to move, and the connecting plate 44 drives the push rod 43 to move, and the outer shell is pushed out by the push rod 43 until it moves to the top of the workbench 1 and stops moving.

[0062] like Figure 3 and Figure 4 As shown, a first motor 47 is fixedly connected to the inner wall of the bottom of the working box 41, and an L-shaped plate 471 is fixedly connected to the output shaft of the first motor 47; a mounting seat 482 is fixedly connected to the side wall of the working box 41, and a circular plate 481 is rotatably connected to the mounting seat 482 through a bearing; a mounting frame 473 is fixedly connected to the bottom of the circular plate 481, and the L-shaped plate 471 is fixedly connected to the bottom of the mounting frame 473; four threaded rods 483 are rotatably connected to the circular plate 481 through bearings, and a hammer block 484 is threadedly connected to the threaded rod 483, and the bottom of the threaded rod 483 extends to the bottom of the circular plate 481 , and is fixedly connected with a first gear 485; the bottom of the circular plate 481 is rotatably connected with a second gear 486 through a rotating rod 487, and the first gear 485 is meshed with the second gear 486; the bottom end of the rotating rod 487 is fixedly connected with a rotating plate 472, and a limiting opening 475 is provided at one end of the rotating plate 472 away from the rotating rod 487, and the rotating plate 472 is rotatably connected to the mounting frame 473 through a pin shaft; a second motor 48 is fixedly connected to the L-shaped plate 471, and the output shaft of the second motor 48 is fixedly connected to a limiting block 474, and the limiting block 474 is slidably connected in the limiting opening 475 through a limiting shaft.

[0063] When the first gear 485 and the second gear 486 provided by the present invention are in use, since the injection molding liquid is in a viscous molten state, bubbles may be present in the injection molding liquid when it is input. If they are not eliminated, bubbles may be present in the shell, resulting in quality problems. After the injection molding is completed, the shell may be attached to the lower mold 4, which is inconvenient to be directly removed. If it is pushed out vigorously, the shell may be damaged. Therefore, the second motor 48 needs to be turned on when the injection molding liquid is input and the material is discharged, and the second motor 48 drives the limit block 474 to rotate. When the limit block 474 rotates, it drives the limit shaft to rotate. When the limit shaft rotates, the limit opening 474 is simultaneously opened. 5, the rotating plate 472 is driven to swing back and forth around the pin shaft by squeezing the limit opening 475, the rotating rod 487 is driven to swing back and forth by the rotating plate 472, the second gear 486 is driven to rotate back and forth by the rotating rod 487, the four first gears 485 are driven to rotate back and forth by the second gear 486, the threaded rod 483 is driven to rotate back and forth by the first gear 485, the hammer block 484 is driven to rotate back and forth by the threaded rod 483, the lower mold 4 is knocked by the hammer block 484, and under the influence of the vibration wave, the lower mold 4 is separated from the shell, and then the ejector rod 43 is used to facilitate ejection;

[0064] During operation, the hammer block 484 turns on the first motor 47, and the output shaft of the first motor 47 drives the L-shaped plate 471, the mounting frame 473 and the circular plate 481 to rotate, and the circular plate 481 drives the hammer block 484 to rotate, thereby increasing the hammering area and accelerating the separation of the lower mold 4 and the shell.

[0065] like Figure 2 and Figure 8 As shown, fins 49 are fixedly connected to both side walls of the lower mold 4 ; a heat dissipation box 46 is fixedly connected to the side wall of the working box 41 , and a heat dissipation fan 45 is installed in the heat dissipation box 46 .

[0066] When the fins 49 and the cooling fan 45 provided by the present invention are in use, the cooling area of ​​the lower mold 4 is increased by the fins 49 to accelerate the heat dissipation, and the heat in the working box 41 is discharged by the cooling fan 45, so as to facilitate the heat dissipation and cooling of the lower mold 4.

[0067] like Figure 5 As shown, two guide rods 56 are fixedly connected between the two side walls of the moving frame 51 , and the moving plate 5 slides on the two guide rods 56 .

[0068] When the guide rod 56 provided by the present invention is in use, the movable plate 5 slides on the guide rod 56 during the movement of the movable plate 5, and the guide rod 56 limits the movable plate 5 to move in the horizontal direction.

[0069] like Fig.11 As shown, a method for manufacturing an electrical equipment housing comprises the following steps:

[0070] S1: First, the upper mold 34 is moved into the lower mold 4 to form a mold cavity, and the molten plastic is injected into the mold cavity under high pressure;

[0071] S2: After injection molding, the plastic is cooled and solidified in the mold cavity to obtain a molded shell;

[0072] S3: The upper mold 34 is moved out, and the shell is ejected by the hammering structure and the ejection structure;

[0073] S4: The shell is taken out through the clamping plate 58 and placed on the conveyor belt 6, and is transported by the conveyor belt 6;

[0074] S5: During the conveying process, defective shells are identified through scanning and removed, while shells without defects continue to be conveyed.

[0075] Working principle: The molten injection liquid is injected into the inner cylinder 21 through the liquid inlet pipe 23, and passes through the filter basket 24 during the injection process. The filter basket 24 filters the impurities in the injection liquid to prevent the impurities from causing bubbles in the shell and poor shell quality during injection. The filter basket 24 is clogged by impurities after a period of time, affecting the speed of infusion. Therefore, a spring 26 and a scraper 25 are provided. During infusion, under the action of the spring 26, the scraper 25 slides up and down to scrape the impurities on the inner wall of the filter basket 24 to maintain the flow rate of the infusion. The heating tube 27 is provided to maintain the temperature of the injection liquid in the inner cylinder 21 to prevent cooling and solidification.

[0076] By turning on the cylinder 31, the lifting plate 32 is driven to move through the output end of the cylinder 31, and the upper mold 34 is driven to move through the lifting plate 32. The upper mold 34 cooperates with the lower mold 4 to form a mold cavity, which is convenient for injection molding of the injection liquid in the mold cavity;

[0077] First, the formed shell needs to be ejected, and the second motor 48 needs to be turned on. The second motor 48 drives the limit block 474 to rotate. The limit block 474 drives the limit shaft to rotate when rotating. When the limit shaft rotates, it slides in the limit opening 475 at the same time. The rotating plate 472 is driven to swing back and forth around the pin shaft by squeezing the limit opening 475. The rotating plate 472 drives the rotating rod 487 to swing back and forth. The rotating rod 487 drives the second gear 486 to rotate back and forth. The second gear 486 drives the four first gears 485 to rotate back and forth. 85 drives the threaded rod 483 to rotate back and forth, and drives the hammer block 484 to rotate back and forth through the threaded rod 483, and knocks the lower mold 4 through the hammer block 484, so that the lower mold 4 and the shell are separated under the influence of the vibration wave, and then the ejector rod 43 is used to facilitate ejection; during the operation process, the hammer block 484 turns on the first motor 47, and the output shaft of the first motor 47 drives the L-shaped plate 471, the mounting frame 473 and the circular plate 481 to rotate, and the circular plate 481 drives the hammer block 484 to rotate, thereby increasing the hammering area and accelerating the separation of the lower mold 4 and the shell;
