Abstract

This invention discloses a rapid mold changing device for an injection molding machine, relating to the field of powder metallurgy technology. It includes a primary operating platform, with a hydraulic telescopic column fixedly installed on the outer wall of its top. A discharge port is provided on one side of the outer wall of the primary operating platform. A water storage tank is located inside the primary operating platform. A moving groove is provided on the outer wall of the top of the primary operating platform. A secondary operating platform is fixedly installed on one side of the outer wall of the primary operating platform, and an installation box is fixedly installed on the outer wall of the top of the secondary operating platform. This invention utilizes a limiting slider that slides within a limiting groove, causing the limiting slide plate to disengage from the lower surface of a flipping plate.

This solves the problem of slow mold changing speed in existing injection molding machine mold changing devices.

Description

Technical Field

[0001] This invention relates to the field of powder metallurgy technology, and more specifically to a quick mold change device for injection molding machines. Background Technology

[0002] Injection molding machines are the main equipment for manufacturing compression molded products. During operation, it is necessary to assemble and replace the molds used for product molding. Currently, the traditional method of installing and disassembling molds on injection molding machines is manual operation using bolts and pressure plates. Because this method requires manual installation by the mold installer throughout the entire mold change process, it is limited by factors such as the mold installer's experience, physical strength, and working time. The efficiency of the mold installation process is low, and it is difficult to effectively guarantee the length of the mold installation time, which limits the scope of application of injection molding machines.

[0003] For example, Chinese Patent CN113954299A discloses a quick mold change device for an injection molding machine. Both the fixed part and the movable part have an "L"-shaped cross-section. The vertical plate of the fixed part has a through hole, and the vertical plate of the movable part has a screw hole. Both the through hole and the screw hole match the adjusting component. The adjusting component includes a drive motor, which is mounted on the horizontal plate of the fixed part. The drive motor is connected to an adjusting rod via a coupling. The adjusting rod passes through the through hole and is rotatably connected to the fixed part via a bearing. The outer wall of the end of the adjusting rod away from the through hole has a part that matches the screw hole. The adjusting rod is threaded at one end away from the through hole and threaded to the screw hole. The tail end of the adjusting rod is fixed. A fixing plate is provided on the base, and a limiting block is provided on the outer wall of the fixing plate. A limiting rod is provided on the side wall of the sliding plate, and the limiting rod matches the limiting block. By placing the new mold in the first placement cavity, the second placement cavity is used to place the original mold. By utilizing the cooperation between the sliding plate, electric push rod, air extraction device and suction cup, the original mold on the injection molding machine is taken out and moved to a suitable position inside the second placement cavity, and the new mold is installed and placed. The whole process is automated, avoiding the trouble caused by manual installation by the staff.

[0004] The existing technology has the following problems:

[0005] Existing quick mold change devices for injection molding machines require manual installation by the mold installer, leading to slow manual operation. Furthermore, these devices cause the injection material to wait during injection, resulting in insufficient cooling and affecting the quality of the finished product. Additionally, the hot mold after injection can negatively impact the internal cooling time. Summary of the Invention

A first motor is fixedly installed on the outer wall of one side of the second operating platform.

[0009] A further improvement of the technical solution of the present invention is that: a rolling roller is fixedly installed on the outer wall of one end of the first motor and on the inner side of the transmission plate; a movable plate is fixedly installed on the outer wall of one end of the hydraulic telescopic column; and a limiting side plate is fixedly installed on the outer wall of the top of the movable plate.

[0010] A further improvement of the technical solution of the present invention is that: a rotating column is rotatably connected to the inner side of the top of the limiting side plate, a flipping plate is fixedly connected to the outer wall of the rotating column, and a stop block is fixedly connected to the top of the inner wall of the first operating platform and the lower surface of the moving groove.

[0011] A further improvement of the technical solution of the present invention is that: a limiting groove is provided on the inner side of the bottom of the movable plate, a limiting slider is slidably connected to the inner side of the limiting groove, a limiting slide plate is fixedly installed at one end of the bottom of the limiting slider, and a limiting block is fixedly connected to the outer wall of the bottom of the limiting slide plate.

[0012] A further improvement of the technical solution of the present invention is that: a fixing frame is fixedly installed on the inner wall of the mixing tank, and a rotating rod is fixedly installed on the outer wall of the bottom of the second motor.

[0013] A further improvement of the technical solution of the present invention is that: a stirring blade is fixedly installed on the outer wall of the rotating rod and on the inner side of the fixed frame; a heating tube is fixedly installed on the outer wall of the fixed frame; and a No. 3 motor is fixedly installed inside the mounting box.

[0014] A further improvement of the technical solution of the present invention is that: an injection tube is fixedly installed inside the mounting box and at one end located at the bottom of the mixing tank; a transmission rod is fixedly installed at one end of the No. 3 motor and inside the injection tube; and a transmission blade is fixedly connected to the outer wall of the transmission rod.

[0015] A further improvement of the technical solution of the present invention is that: an installation frame is fixedly installed on the inner wall of the first operating platform, and a second rolling roller is rotatably connected to the inner side of the installation frame.

[0016] A further improvement of the technical solution of the present invention is that: a water pump is fixedly installed inside the water storage tank, a water transmission pipe is fixedly installed on the outer wall of the water pump, and a spray hole is fixedly installed on the outer wall of the water transmission pipe.

[0017] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0018] This invention provides a rapid mold changing device for injection molding machines. It employs a primary motor, transmission plate, primary rolling roller, hydraulic telescopic column, moving plate, limiting side plate, rotating column, flipping plate, stop block, limiting slide groove, limiting slider, limiting slide plate, and limiting block in coordination. When the moving plate is pushed, the stop block blocks the limiting block, causing the limiting block to drive the limiting slide plate. The limiting slide plate then drives the limiting slider to slide inside the limiting slide groove, pushing the limiting slide plate to the lower surface of the flipping plate and limiting its position. After injection molding, the hydraulic telescopic column pulls the moving plate, causing another stop block to block the limiting block, thus pulling the limiting slide plate. This causes the limiting slider to slide inside the limiting slide groove, disengaging the limiting slide plate from the lower surface of the flipping plate. Without the limiting slide plate securing the upper surface of the flipping plate, the rotating columns on both sides of the flipping plate rotate, causing the mold to fall into the primary operating table. This solves the problem of slow mold changing speed in existing injection molding machine devices.

[0019] This invention provides a quick mold change device for an injection molding machine. It employs a mixing tank, a fixed frame, a second motor, a rotating rod, stirring blades, a heating element, a third motor, an injection tube, and a transmission rod, with the transmission rods working in coordination. The injection material is placed inside the mixing tank. The second motor is then activated, causing the rotating rod to rotate, which in turn drives the stirring blades to stir the injection material inside the mixing tank. The heating element is then energized, generating heat, which, combined with the stirring blades, prevents the injection material from cooling. The injection material is then discharged into the injection tube. Finally, the third motor is activated, causing the transmission rod inside the injection tube to rotate, which in turn drives the transmission blades to push the injection material out of one end of the injection tube and into the mold. This solves the problem of the injection material cooling down easily while waiting for injection in existing injection molding machines.

[0020] This invention provides a quick mold change device for an injection molding machine. It employs a coordinated mechanism involving a primary operating platform, a mounting frame, a secondary rolling roller, a water storage tank, a water pump, a transmission water pipe, and spray nozzles. The mold falls into the primary operating platform and then onto the secondary rolling roller inside the mounting frame. The rolling roller guides the mold to the discharge port for discharge. Simultaneously, the water pump inside the water storage tank is activated, drawing water from the tank into the transmission water pipe. This water is then sprayed through the nozzles, effectively cooling the mold and solving the problem of excessively hot molds immediately after injection molding. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to embodiments: Example

[0029] like Figure 1-6 As shown, the present invention provides a quick mold change device for an injection molding machine, including a first operating platform 1, a hydraulic telescopic column 2 fixedly installed on the outer wall of the top of the first operating platform 1, a discharge port 22 opened on the outer wall of one side of the first operating platform 1, a water storage tank 16 opened inside the first operating platform 1, a moving groove 8 opened on the outer wall of the top of the first operating platform 1, a third operating platform 15 fixedly installed on the outer wall of one side of the first operating platform 1, an installation box 9 fixedly installed on the outer wall of the top of the third operating platform 15, a mixing tank 10 fixedly installed on the outer wall of the top of the installation box 9, a second motor 11 fixedly installed on the outer wall of the top of the mixing tank 10, a second operating platform 4 fixedly installed on the outer wall of one side of the first operating platform 1, a storage groove 5 fixedly installed on the outer wall of the top of the second operating platform 4, a transmission plate 7 fixedly installed on the outer wall of the top of the second operating platform 4 and on the outer wall of the storage groove 5, and a first motor 6 fixedly installed on the outer wall of one side of the second operating platform 4.

[0030] In this embodiment, the hydraulic telescopic column 2 is first activated, and one end of the hydraulic telescopic column 2 pushes the moving plate 3 to one side of the transmission plate 7. Then, the mold is placed inside the storage slot 5, and the first motor 6 is activated. One end of the first motor 6 drives the first rolling roller 12 on the inner side of the transmission plate 7 to rotate, thereby guiding the mold to the outer wall of the other first rolling roller 12. The first end of the first motor 6 drives the first rolling roller 12 on the inner side of the transmission plate 7 to rotate, thereby guiding the mold to the outer wall of the other first rolling roller 12. Thus, the mold slides to the upper surface of the moving plate 3 on the outer wall of the first rolling roller 12, and is then limited by the limiting side plate 13, causing the mold to slide down to the upper surface of the flipping plate 14. Example

[0031] like Figure 1-6 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, a first rolling roller 12 is fixedly installed on the outer wall of one end of the first motor 6 and on the inner side of the transmission plate 7; a moving plate 3 is fixedly installed on the outer wall of one end of the hydraulic telescopic column 2; a limiting side plate 13 is fixedly installed on the outer wall of the top of the moving plate 3; a rotating column 24 is rotatably connected to the inner side of the top of the limiting side plate 13; a flipping plate 14 is fixedly connected to the outer wall of the rotating column 24; a stop block 23 is fixedly connected to the top of the inner wall of the first operating platform 1 and on the lower surface of the moving groove 8; a limiting slide groove 33 is opened on the inner side of the bottom of the moving plate 3; a limiting slider 34 is slidably connected to the inner side of the limiting slide groove 33; a limiting slide plate 35 is fixedly installed at one end of the bottom of the limiting slider 34; and a limiting block 36 is fixedly connected to the outer wall of the bottom of the limiting slide plate 35.

[0032] In this embodiment, when the movable plate 3 is pushed, the stop block 23 abuts against the limiting block 36, thereby causing the limiting block 36 to drive the limiting slide plate 35. The limiting slide plate 35 then drives the limiting slider 34 to slide inside the limiting groove 33, thus pushing the limiting slide plate 35 to the lower surface of the flipping plate 14 and limiting the flipping plate 14. After injection molding, the movable plate 3 is pulled by the hydraulic telescopic column 2, causing another stop block 23 to abut against the limiting block 36, thereby pulling the limiting slide plate 35 and causing the limiting slider 34 to slide inside the limiting groove 33. This causes the limiting slide plate 35 to detach from the lower surface of the flipping plate 14. Without the fixing of the limiting slide plate 35 on the upper surface of the flipping plate 14, the rotating columns 24 on both sides of the flipping plate 14 rotate, causing the mold to fall into the interior of the first operating table 1. Example

[0033] like Figure 1-6 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, a fixing frame 27 is fixedly installed on the inner wall of the mixing tank 10, a rotating rod 26 is fixedly installed on the outer wall of the bottom of the second motor 11, a stirring blade 25 is fixedly installed on the outer wall of the rotating rod 26 and inside the fixing frame 27, a heating tube 28 is fixedly installed on the outer wall of the fixing frame 27, a third motor 29 is fixedly installed inside the mounting box 9, an injection molding tube 32 is fixedly installed at one end of the mounting box 9 and at the bottom of the mixing tank 10, a transmission rod 30 is fixedly installed at one end of the third motor 29 and inside the injection molding tube 32, and a transmission blade 31 is fixedly connected to the outer wall of the transmission rod 30.

[0034] In this embodiment, the injection molding material is placed inside the mixing tank 10. Then, the second motor 11 is started, causing the rotating rod 26 to rotate. This causes the rotating rod 26 to drive the stirring blade 25 to stir the injection molding material inside the mixing tank 10. Then, the heating tube 28 is energized, causing it to heat up. Combined with the stirring blade 25, this stirs the injection molding material inside the mixing tank 10, preventing it from cooling down. The injection molding material is then discharged into the injection tube 32. The third motor 29 is then started, causing the transmission rod 30 inside the injection tube 32 to rotate. This causes the transmission blade 31 to push the injection molding material, allowing it to be discharged from one end of the injection tube 32 into the mold. Example

[0035] like Figure 1-6 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, an installation frame 20 is fixedly installed on the inner wall of the first operating platform 1, a second rolling roller 21 is rotatably connected to the inner side of the installation frame 20, a water pump 17 is fixedly installed inside the water storage tank 16, a transmission water pipe 18 is fixedly installed on the outer wall of the water pump 17, and a spray hole 19 is fixedly installed on the outer wall of the transmission water pipe 18.

[0036] In this embodiment, the mold falls into the interior of the first operating platform 1, causing it to fall onto the second rolling roller 21 inside the mounting frame 20. The mold is then rolled by the second rolling roller 21 and guided to the discharge port 22 for discharge. While the mold is inside the first operating platform 1, the water pump 17 inside the water storage tank 16 is activated. The water pump 17 draws water from the water storage tank 16 into the transmission water pipe 18, which then sprays the water through the transmission water pipe 18 to the spray nozzles 19, thereby cooling the mold.

[0037] The working principle of this injection molding machine's quick mold change device will be explained in detail below.

[0038] like Figure 1-6As shown, firstly, the hydraulic telescopic column 2 is activated, pushing the moving plate 3 through one end of the hydraulic telescopic column 2. The moving plate 3 is pushed to one side of the transmission plate 7. When the moving plate 3 is pushed, the stop block 23 blocks the limiting block 36, thereby causing the limiting block 36 to drive the limiting slide plate 35. The limiting slide plate 35 then drives the limiting slider 34 to slide inside the limiting slide groove 33, thus pushing the limiting slide plate 35 to the lower surface of the flipping plate 14 and limiting the flipping plate 14. Then, the mold is placed inside the storage slot 5, and then the first motor 6 is activated. One end of the first motor 6 drives the first rolling roller 12 inside the transmission plate 7 to rotate, thereby guiding the mold to other... The outer wall of the first rolling roller 12 allows the mold to slide onto the upper surface of the moving plate 3. Then, the limiting side plate 13 limits the mold, causing it to slide onto the upper surface of the flipping plate 14. The moving plate 3 is then pushed to one end of the injection tube 32 by one end of the hydraulic telescopic column 2. The injection material is then placed inside the mixing tank 10. The second motor 11 is then started, causing the rotating rod 26 to rotate. This rotating rod 26 then drives the stirring blades 25 to stir the injection material inside the mixing tank 10. The heating tube 28 is then energized, causing it to heat up, which in turn stimulates the stirring blades 25. The injection molding material inside the mixing tank 10 is stirred to prevent it from cooling down. Then, the injection molding material is discharged into the injection tube 32. The third motor 29 is started, which drives the transmission rod 30 inside the injection tube 32 to rotate, thereby driving the transmission blade 31 to push the injection molding material, causing it to be discharged from one end of the injection tube 32 into the mold. After injection molding, the hydraulic telescopic column 2 pulls the moving plate 3, causing another stop block 23 to block the limiting block 36, thereby pulling the limiting slide plate 35. This causes the limiting slider 34 to slide inside the limiting groove 33, disengaging the limiting slide plate 35 from the lower surface of the flip plate 14. The upper surface of the flipping plate 14 lacks the fixing of the limiting slide plate 35, causing the rotating columns 24 on both sides of the flipping plate 14 to rotate, thereby causing the mold to fall into the interior of the first operating table 1. When the mold falls into the interior of the first operating table 1, it falls into the second rolling roller 21 inside the mounting frame 20, causing the mold to roll through the second rolling roller 21 and be guided to the discharge port 22 for discharge. When the mold falls into the interior of the first operating table 1, the water pump 17 inside the water storage tank 16 is started, and the water pump 17 leads the water inside the water storage tank 16 into the transmission water pipe 18, and the water is sprayed through the transmission water pipe 18 to the spray nozzle 19, thereby cooling the mold.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
