Description

Technical Field

[0001] The present invention belongs to the technical field of plastic injection molding processing, and particularly relates to an automatic demolding device for plastic injection molding processing. Background Art

[0002] A plastic injection molding machine is also called a plastic injection molding machine or a plastic injection machine. It is the main molding equipment for making various shaped plastic products by using a plastic molding die with thermoplastic or thermosetting plastics. Plastic injection molding machines are divided into vertical, horizontal, and all-electric types. A plastic injection molding machine can heat plastics, apply high pressure to the molten plastics, and inject them to fill the die cavity. The demolding mechanism of a plastic injection mold is an important part of the injection mold, which is used to separate the molded plastic product from the mold.

[0003] The existing automatic demolding devices for plastic injection molding processing generally eject the injection molded parts from the mold directly through a pneumatic device. However, for larger injection molded parts, the friction between them and the mold is relatively large, and thermal adhesion easily occurs between the injection molded parts and the inner wall of the mold. When the pneumatic device ejects, it is easy to cause a large impact force on the injection molded parts; and when a general pulling device pulls the injection molded parts, indentations will be formed on the surface of the injection molded parts, resulting in damage to the appearance of the injection molded parts. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic demolding device for plastic injection molding processing, aiming to solve the technical problems in the prior art that when the pneumatic device ejects, it is easy to cause a large impact force on the injection molded parts; and when a general pulling device pulls the injection molded parts, indentations will be formed on the surface of the injection molded parts, resulting in damage to the appearance of the injection molded parts.

A water pipe is connected between the second water pump and the upper end of the first electric telescopic sleeve, and a rotating joint is connected between the water pipe and the fixed end of the first electric telescopic sleeve. The first electric telescopic sleeve is communicated with the heat conduction plate.

[0011] Further technical solution: The power assembly includes a second motor and a belt transmission pair. The second motor is fixedly connected with the rotating frame, and a belt transmission pair is connected between the output shaft of the second motor and the fixed end of the first electric telescopic sleeve.

[0012] Further technical solution: The adjusting mechanism includes an electric telescopic rod, a scraping strip, a capsule and a gear;

[0013] A plurality of electric telescopic rods are rotatably connected to the telescopic end of the first electric telescopic sleeve. The telescopic end of the electric telescopic rod is fixedly provided with a plurality of scraping strips, and all the scraping strips are inclined in one rotation direction. Capsules are arranged in all the scraping strips, and all the capsules are communicated with the telescopic end of the electric telescopic rod. The electric telescopic rods are all communicated with the first electric telescopic sleeve.

One end of the rotating frame is fixedly connected to the gear sleeve. The gear sleeve is rotatably connected to the support frame and meshes with the driving wheel.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. First, start the heat absorption mechanism to perform contact cooling on the surface of the injection molded part, avoiding subsequent thermal adhesion between the pulling mechanism and the upper surface of the injection molded part. All adjusting mechanisms can clean the burrs on the surface of the injection molded part, thereby avoiding insufficient fitting between the subsequent pulling mechanism and the upper end surface of the injection molded part. Then, while all pulling mechanisms jointly adsorb the surface of the injection molded part, the pulling mechanisms jointly pull the injection molded part upward out of the lower mold. During this process, the pulling mechanisms can detect the pose change of the injection molded part during movement;

[0020] 2. The pulling mechanisms can detect the pose change of the injection molded part during movement. Then, when the injection molded part is tilted and stuck in the lower mold, all adjusting mechanisms can adjust the pose of the injection molded part. During this process, the thrust mechanism provides an upward thrust to the injection molded part, thereby preventing the pulling mechanism from detaching from the injection molded part;

[0021] 3. All cooling mechanisms can jointly cool the injection molded part in the lower mold. When the pulling mechanism detects that the viscosity between one side wall of the injection molded part and the corresponding side wall of the lower mold is too high, the cooling mechanism on the outer side of the corresponding side wall of the lower mold will increase its own power to enhance the cooling effect at the sticky part of the lower mold, avoiding similar sticky situations in subsequent production processes.

[0022] 4. When adjusting the pose of the surface of the injection-molded part, the second water pump increases the water pressure in the electric sleeve rod through the first electric telescopic sleeve. The water pressure in all the capsules connected to the electric sleeve rod increases. At this time, the extrusion force between the capsules and the upper surface of the injection-molded part increases. The first electric telescopic sleeve drives all the electric sleeve rods to rotate around the axis of the first electric telescopic sleeve. At this time, the electric sleeve rod presses on the entire surface of the injection-molded part through the pressure, so that the upwardly warped part of the injection-molded part moves downward, so that the injection-molded part is disengaged from the clamping with the inner wall of the lower mold. Further, the scraping strip drives the capsule to rotate along the upper surface of the injection-molded part, which can correct the pose of the injection-molded part while avoiding forming indentations on the surface of the injection-molded part.

Detailed Embodiments

[0031] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] The following describes in detail the specific implementation of the present invention in conjunction with specific embodiments.

[0033] As Figures 1 - 7 shown, an automatic demolding device for plastic injection molding processing provided by the present invention includes an injection molding table 1. A lower mold 11 is fixedly connected to the middle of the injection molding table 1. A support frame 2 is fixedly connected to the upper end surface of the injection molding table 1. The support frame 2 is fixedly connected with a driving rod 12. The telescopic end of the driving rod 12 is fixedly connected with an upper template 13. A rotating frame 14 is rotatably connected to the support frame 2. A driving assembly 3 for driving the rotating frame 14 to rotate is arranged on the support frame 2. A second electric telescopic sleeve 15 is fixedly connected to the lower end surface of the rotating frame 14. The second electric telescopic sleeve 15 is fixedly connected with a fixing frame 16. The fixing frame 16 is cross-shaped, and a tension mechanism 5 is arranged on each end surface of the fixing frame 16. All the tension mechanisms 5 are commonly connected to a second air pump 10. While all the tension mechanisms 5 can jointly adsorb the surface of the injection molded part, the tension mechanisms 5 jointly pull the injection molded part upward out of the lower mold 11, and the tension mechanism 5 can detect the pose change when the injection molded part moves;

[0034] The rotating frame 14 is rotatably connected with a heat absorption mechanism 6. The heat absorption mechanism 6 can perform contact heat dissipation on the surface of the injection molded part. A power assembly 7 is arranged on the rotating frame 14. The power assembly 7 can drive the heat absorption mechanism 6 to rotate. The heat absorption mechanism 6 is connected with a plurality of adjustment mechanisms 8. All the adjustment mechanisms 8 can simultaneously clean the burrs on the surface of the injection molded part. Additionally, when the injection molded part is tilted and stuck in the lower mold 11, all the adjustment mechanisms 8 can adjust the pose of the injection molded part;

[0035] Cooling mechanisms 4 are communicated with the four side walls of the lower mold 11. All the cooling mechanisms 4 can jointly cool the injection molded part in the lower mold 11. The lower mold 11 is connected with a thrust mechanism 9. The thrust mechanism 9 can apply air pressure to the injection molded part in the lower mold 11.

[0036] In this embodiment, when the injection molded part in the lower mold 11 is cooled, the driving rod 12 is started to drive the upper template 13 to open, and the driving assembly 3 is started to drive the rotating frame 14 to rotate. The rotating frame 14 drives all the tension mechanisms 5 to move above the injection molded part;

[0037] First, start the endothermic mechanism 6 to conduct contact heat dissipation on the surface of the injection-molded part. All the adjusting mechanisms 8 can clean the burrs on the surface of the injection-molded part. Then, while all the pulling mechanisms 5 jointly adsorb the surface of the injection-molded part, the pulling mechanisms 5 jointly pull the injection-molded part upward out of the lower mold 11. During this process, the pulling mechanisms 5 can detect the pose change of the injection-molded part when it moves.

[0038] When the injection-molded part moves upward, since the injection-molded part is prone to thermal adhesion to the inner wall of the lower mold 11, the frictions on the four side walls of the injection-molded part are different, resulting in the injection-molded part being prone to tilting when moving upward in the lower mold 11, thus causing the injection-molded part to get stuck in the lower mold 11.

[0039] In this embodiment, the pulling mechanisms 5 can detect the pose change of the injection-molded part when it moves. Then, when the injection-molded part tilts and gets stuck in the lower mold 11, all the adjusting mechanisms 8 can adjust the pose of the injection-molded part. During this process, the thrust mechanism 9 provides an upward thrust to the injection-molded part, thus preventing the pulling mechanisms 5 from detaching from the injection-molded part.

[0040] All the cooling mechanisms 4 can jointly cool the injection-molded part in the lower mold 11. When the pulling mechanism 5 detects that the viscosity between one side wall of the injection-molded part and the corresponding side wall of the lower mold 11 is too high, the cooling mechanism 4 outside the corresponding side wall of the lower mold 11 will increase its own power to enhance the cooling effect of the sticky part of the lower mold 11 and avoid similar sticky situations in the subsequent production process.

[0041] As Figure 5 shown, an automatic demolding device for plastic injection molding provided by the present invention, the pulling mechanism 5 includes a sleeve 51, a spring 52, an upper boss 53 and a suction cup 54;

[0042] The bottom end of the sleeve 51 is fixedly connected with a suction cup 54. The sleeve 51 is communicated with the suction cup 54. An upper boss 53 and a lower boss 55 are fixedly connected to the sleeve 51. One end of the fixed frame 16 is slidably connected between the upper boss 53 and the lower boss 55. The spring 52 is arranged between the upper boss 53 and the fixed frame 16. A pressure sensor is arranged between the spring 52 and the upper boss 53.

[0043] In this embodiment, start the second electric telescopic sleeve 15 to extend. The second electric telescopic sleeve 15 drives the fixed frame 16 to move downward. The fixed frame 16 pushes all the suction cups 54 to adsorb on the upper surface of the injection-molded part. Then, start the second air pump 10. The second air pump 10 pumps out the air inside the sleeve 51, thereby forming a negative pressure environment in the sleeve 51, so that the suction cup 54 is adsorbed and fixed on the surface of the injection-molded part.

[0044] After that, start the second electric telescopic sleeve 15 to contract. The second electric telescopic sleeve 15 pulls all the sleeves 51 through the fixing frame 16, and all the sleeves 51 pull the injection molded part upward together. At this time, all the springs 52 contract elastically.

[0045] When the pressure difference between each pressure sensor exceeds the preset pressure difference threshold, it indicates that the upper surface of the injection molded part is tilted at this time, and the injection molded part is stuck in the lower mold 11. At this time, the adjustment mechanism 8 is activated to adjust the position and posture of the injection molded part.

[0046] As Figure 6 shown, the present invention provides an automatic demoulding device for plastic injection molding. The heat absorption mechanism 6 includes a first electric telescopic sleeve 61 and a heat conducting disc 62. The fixed end of the first electric telescopic sleeve 61 is fixedly connected to the injection molding table 1. The telescopic end of the first electric telescopic sleeve 61 is rotatably connected to the heat conducting disc 62. A water tank 63 is fixedly connected to the rotating frame 14. The water tank 63 is connected to a second water pump 64. A water pipe is connected between the second water pump 64 and the upper end of the first electric telescopic sleeve 61. A rotating joint is connected between the water pipe and the fixed end of the first electric telescopic sleeve 61. The first electric telescopic sleeve 61 is communicated with the heat conducting disc 62.

[0047] In this embodiment, when demoulding the plastic part in the lower mold 11, first start the first electric telescopic sleeve 61 to extend. The first electric telescopic sleeve 61 drives the heat conducting disc 62 to move downward. The heat conducting disc 62 performs contact cooling on the upper surface of the injection molded part to avoid thermal adhesion between the suction cup 54 and the injection molded part.

[0048] As Figure 4 shown, the present invention provides an automatic demoulding device for plastic injection molding. The power assembly 7 includes a second motor 71 and a belt transmission pair 72. The second motor 71 is fixedly connected to the rotating frame 14. A belt transmission pair 72 is connected between the output shaft of the second motor 71 and the fixed end of the first electric telescopic sleeve 61.

[0049] In this embodiment, start the second motor 71. The second motor 71 can drive the first electric telescopic sleeve 61 to rotate through the belt transmission pair 72.

[0050] As Figure 7 shown, the present invention provides an automatic demoulding device for plastic injection molding. The adjustment mechanism 8 includes an electric telescopic rod 81, a scraping strip 82, a capsule 83 and a gear 84;

[0051] The telescopic end of the first electric telescopic sleeve 61 is rotatably connected to a plurality of electric telescopic rods 81. The telescopic ends of the electric telescopic rods 81 are fixedly provided with a plurality of scraping bars 82. All the scraping bars 82 are inclined in one rotational direction. Capsules 83 are arranged in all the scraping bars 82. All the capsules 83 are communicated with the telescopic ends of the electric telescopic rods 81. The electric telescopic rods 81 are all communicated with the first electric telescopic sleeve 61. The fixed ends of the electric telescopic rods 81 are fixedly connected with gears 84. All the gears 84 can be meshed with the upper end surface of the heat conducting plate 62.

[0052] In this embodiment, when cleaning the burrs on the surface of the injection molded part, start all the electric telescopic rods 81 to extend. At this time, driven by the power assembly 7, the first electric telescopic sleeve 61 drives all the electric telescopic rods 81 to perform circular motion around the axis of the first electric telescopic sleeve 61. At this time, the heat conducting plate 62 abuts against the upper surface of the injection molded part. Under the meshing action between the gear 84 and the upper surface of the heat conducting plate 62, while the electric telescopic rods 81 perform circular motion around the axis of the first electric telescopic sleeve 61, all the electric telescopic rods 81 rotate themselves. All the electric telescopic rods 81 drive all the scraping bars 82 to scrape off the burrs on the surface of the injection molded part. When the burrs are scraped off, stop the start of the first electric telescopic sleeve 61 at this time, and control all the electric telescopic rods 81 to contract and reset. After the burrs on the surface of the injection molded part are scraped off, it can be avoided that the suction cup 54 cannot adsorb and fix on the surface of the injection molded part;

[0053] When adjusting the pose of the surface of the injection molded part, start the second water pump 64. The second water pump 64 increases the water pressure in the electric telescopic rods 81 through the first electric telescopic sleeve 61. The water pressure in all the capsules 83 communicated with the electric telescopic rods 81 increases. At this time, the extrusion force between the capsules 83 and the upper surface of the injection molded part increases. Start the second motor 71. Driven by the second motor 71, the first electric telescopic sleeve 61 drives all the electric telescopic rods 81 to rotate around the axis of the first electric telescopic sleeve 61. At this time, the electric telescopic rods 81 apply pressure to the entire surface of the injection molded part through the pressure, so that the upwardly warped part of the injection molded part moves downward, so that the injection molded part is disengaged from the clamping with the inner wall of the lower mold 11; Further, the scraping bar 82 drives the capsule 83 to rotate along the upper surface of the injection molded part, which can correct the pose of the injection molded part and avoid forming indentations on the surface of the injection molded part at the same time.

[0054] As Figure 3 shown, an automatic demoulding device for plastic injection molding provided by the present invention. The thrust mechanism 9 includes a first air pump 91 and a one-way solenoid valve 92. The first air pump 91 is fixedly connected to the outer end surface of the lower mold 11. The air outlet of the first air pump 91 is communicated with the inside of the lower mold 11. The bottom of the lower mold 11 is communicated with a one-way solenoid valve 92.

[0055] In this embodiment, the first air pump 91 is started to increase the air pressure in the lower mold 11, thereby generating an upward thrust on the injection-molded part. When the air pressure reaches the set value, the thrust mechanism 9 is turned on and exhausts air outward. During this process, while the first air pump 91 applies air pressure to the injection table 1 to help the injection-molded part demold, the first air pump 91 and the one-way solenoid valve 92 cooperate to discharge the hot air in the lower mold 11, thereby accelerating the cooling of the inner wall of the lower mold 11 and the injection-molded part during the demolding process of the injection-molded part. Adjusting the set pressure value of the one-way solenoid valve 92 can control the magnitude of the air pressure thrust on the injection-molded part.

[0056] As Figure 3 shown, an automatic demolding device for plastic injection molding provided by the present invention, the cooling mechanism 4 includes a first water pump 41 and a cooling pipe 42. The four sides of the lower mold 11 are respectively provided with a first water pump 41, and cooling channels are respectively provided on the four side walls of the lower mold 11. Both ends of each cooling channel are communicated with the water inlet and the water outlet of a first water pump 41 through a cooling pipe 42.

[0057] In this embodiment, when the pulling mechanism 5 detects that the adhesion degree between the side wall of the injection-molded part and the corresponding side wall of the lower mold 11 is too large, the first water pump 41 outside the corresponding side wall of the lower mold 11 will increase its own power. The first water pump 41 drives the cooling water to circulate rapidly in the side wall of the lower mold 11, improving the cooling effect of the sticky part of the lower mold 11 and avoiding similar sticky situations in subsequent production processes.

[0058] As Figure 2 shown, an automatic demolding device for plastic injection molding provided by the present invention, the driving assembly 3 includes a first motor 31, a driving wheel 32 and a gear sleeve 33;

[0059] The first motor 31 is fixedly connected to the support frame 2. The output shaft of the first motor 31 is fixedly connected with a driving wheel 32. One end of the rotating frame 14 is fixedly connected with a gear sleeve 33. The gear sleeve 33 is rotatably connected to the support frame 2. The gear sleeve 33 meshes with the driving wheel 32.

[0060] In this embodiment, the first motor 31 is started. The first motor 31 drives the driving wheel 32 to rotate. The driving wheel 32 drives the rotating frame 14 to rotate through meshing with the gear sleeve 33. After the pulling mechanism 5 pulls the injection-molded part out of the lower mold 11, the rotating frame 14 can drive the injection-molded part to transfer to one side.

[0061] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0062] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
