Description

Technical Field

[0001] This utility model relates to the technical field of demolding devices, specifically a linkage demolding device. Background Technology

[0002] Injection molds are molds used for plastic molding. They mainly use injection molding to inject molten plastic into the mold cavity. After the plastic cools and solidifies, it is demolded to obtain the plastic product of the desired shape. Traditional injection molds often have many inconveniences in the demolding process. Traditional molds usually require manual or auxiliary tools to knock, push and pull to remove the injection molded part from the mold cavity. The demolding method is not only cumbersome and inefficient, but also easily damages the injection molded part, affecting the appearance and performance of the product. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 5This utility model provides a technical solution: a linkage demolding device, comprising: a support base 1; a stationary mold 2 fixedly connected to the top of the support base 1; a connecting seat 3 slidably disposed on the top of the support base 1, and a moving mold 4 cooperating with the stationary mold 2 is disposed on one side of the connecting seat 3; a sliding seat 5 slidably disposed inside the connecting seat 3, and a plurality of ejector pins 6 fixedly connected to one side of the sliding seat 5, the ejector pins 6 being slidably connected to the moving mold 4; a sliding column 11 fixedly connected to one side of the sliding seat 5, the sliding seat 5 being slidably connected to the connecting seat 3; and a fixed side box 10 fixedly connected to one side of the connecting seat 3, the sliding column 11 being slidably connected to the fixed side box 10. The limiting slide plate 12 is slidably disposed inside the fixed side box 10, and one end of the sliding column 11 is fixedly connected to the limiting slide plate 12; the second return spring 13 is symmetrically disposed inside the fixed side box 10, one end of the second return spring 13 is fixedly connected to the fixed side box 10, and the other end of the second return spring 13 is fixedly connected to the limiting slide plate 12; the top column 14 is fixedly connected to one side of the limiting slide plate 12, and the top column 14 is slidably connected to the fixed side box 10; the fixed support plate 15 is fixedly connected to the top of the support base 1, and the fixed support plate 15 cooperates with the top column 14; the reset assembly is placed inside the moving mold 4, and the sliding seat 5 is connected to the reset assembly.

[0030] It is understood that this utility model uses an external power supply to power the device and an external controller to operate the device. The output of the motor 22 drives the adjusting screw 20 to rotate. When the adjusting screw 20 rotates, it moves the outer limit slider 19 to adjust the position. The limit slider 19 drives the connecting seat 3 and the moving mold 4 to move, closing the mold between the stationary mold 2 and the moving mold 4. After injection molding is completed, the molded part is demolded when it cools down. The connecting seat 3 and the moving mold 4 are moved to one side, and the moving mold 4 separates from the stationary mold 2. When the connecting seat 3 moves, it drives the fixed side box 10, the sliding column 11, the limit slide plate 12, and the top. The column 14 moves, and the connecting seat 3 drives the sliding seat 18 to slide on the outside of the guide plate 16. When the top column 14 touches one side of the fixed support plate 15, the top column 14 pushes the fixed support plate 15. The top column 14 drives the limiting slide plate 12, the sliding column 11 and the sliding seat 5 to move. The limiting slide plate 12 presses the second return spring 13. At the same time, the sliding seat 5 drives the limiting slide column 8 on one side to press the first return spring 9 in the fixed sleeve 7. The sliding seat 5 drives each ejector pin 6 on one side to move. The ejector pin 6 ejects the injection molded part in the moving mold 4. The injection molded part is demolded in conjunction with the mold opening.

[0031] Please see Figures 1 to 4 The reset assembly includes a fixed sleeve 7, which is symmetrically fixed inside the moving mold 4. A limit slide post 8 is slidably provided inside the fixed sleeve 7. One end of the limit slide post 8 is fixedly connected to the sliding seat 5. A first reset spring 9 is provided inside the fixed sleeve 7. One end of the first reset spring 9 is fixedly connected to the limit slide post 8.

[0032] It is understandable that this utility model uses a first reset spring 9 to assist in resetting the movement of the limiting slide column 8 and the sliding seat 5, so as to facilitate the reset of each ejector pin 6.

[0033] Please see Figures 1 to 5 The support base 1 has a sliding limit slider 19 inside. The top of the limit slider 19 is fixedly connected to the connecting seat 3. The limit slider 19 has an adjusting screw 20 inside. The adjusting screw 20 is rotatably connected to the support base 1.

[0034] It is understood that when the adjusting screw 20 is rotated, the adjusting screw 20 will drive the outer limiting slider 19 to move. When the limiting slider 19 moves, it will drive the connecting seat 3 and the moving mold 4 to move and adjust, which facilitates the mold opening process between the stationary mold 2 and the moving mold 4.

[0035] Please see Figures 1 to 5 A motor 22 is installed on one side of the support base 1. The output end of the motor 22 is fixedly connected to the adjusting screw 20. A limit slider 21 is symmetrically slidably arranged inside the limit slider 19. The limit slider 21 is fixedly connected to the support base 1.

[0036] It is understood that this utility model guides the movement of the limiting slider 19 by using the limiting slide bar 21, thereby improving the stability of the movement of the limiting slider 19.

[0037] Please see Figures 1 to 4 A guide plate 16 is symmetrically fixed to one side of the fixed support plate 15, and a fixed top plate 17 is fixed to one side of the guide plate 16. The bottom of the fixed top plate 17 is fixed to the stationary mold 2. A sliding groove seat 18 is symmetrically fixed to the top of the connecting seat 3. The sliding groove seat 18 is slidably connected to the guide plate 16.

[0038] It is understood that the present invention supports the fixed support plate 15 by means of the guide plate 16 and the fixed top plate 17, and drives the sliding groove seat 18 to move on the outside of the guide plate 16 when the connecting seat 3 moves.

[0039] Please see Figures 1 to 4 Multiple limiting rods 23 are symmetrically slidably arranged inside the sliding seat 5. The limiting rods 23 are fixedly connected to the moving mold 4, and one end of the limiting rods 23 is fixedly connected to the connecting seat 3.

[0040] It is understandable that this utility model guides the sliding position of the sliding seat 5 by using the limiting rod 23, thereby improving the moving stability of the sliding seat 5.
