DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 9As shown, a decorative surface detachable button molding device comprises a movable mold assembly and a fixed mold assembly, the fixed mold assembly comprises a panel 10, a nozzle plate 13 and an upper mold plate 14, a first limiting bolt 12 is arranged on the nozzle plate 13, one end of the first limiting bolt 12 passes through the panel 10 and is fixedly connected to the nozzle plate 13, and is used to limit the mold opening distance between the nozzle plate 13 and the panel 10, a nozzle sleeve 11 is arranged on the panel 10, an injection molding flow channel 32 is arranged on the upper mold plate 14 and the nozzle plate 13, the movable mold assembly comprises a lower mold plate 16, a first slider 24 and a second slider 26, a first molding cavity 30 and a second molding cavity 27 for molding a first fastener 5 and a second fastener 2 are arranged on the lower mold plate 16, four first sliders 24 and four second sliders 26 are arranged on the upper mold plate 14 A driving member 48 is provided on the upper portion for driving the first slider 24 and the second slider 26 to slide horizontally. An ejector is provided below the first slider 24 and the second slider 26. The ejector includes a movable ring 23, a second limiting bolt 25 and a first spring 37. The second limiting bolt 25 passes through the movable ring 23 and is fixedly connected to the lower template 16. The first spring 37 is sleeved on the outer side of the second limiting bolt 25, and the two ends of the first spring 37 are respectively in contact with the movable ring 23 and the lower template 16. A pressure block 38 for slidingly guiding the first slider 24 and the second slider 26 is fixedly installed on the movable ring 23. A pressure rod 17 for resetting the movable ring 23 is fixedly installed on the upper template 14. A sequential mold opening assembly 15 is provided between the sprue plate 13, the upper template 14 and the lower template 16.

[0023] The driving member 48 includes a fixed block 21 and an inclined guide column 22. The fixed block 21 is fixed to the upper template 14 by bolts, and a first wedge surface 18 is provided on the fixed block 21. The inclined guide column 22 is fixed to the fixed block 21. The first wedge surface 18 and the inclined guide column 22 have the same inclination direction, and the inclination angle of the first wedge surface 18 is greater than the inclination angle of the inclined guide column 22. The first slider 24 and the second slider 26 are both provided with an inclined hole 28 that cooperates with the inclined guide column 22. When the upper template 14 and the lower template 16 are opened, the fixed block 21 is no longer in conflict with the first slider 24 and the second slider 26. At this time, the position of the inclined guide column 22 in the inclined hole 28 changes, so that the inclined guide column 22 can drive the first slider 24 and the second slider 26 to slide horizontally along the pressing block 38, thereby smoothly separating from the first clamping protrusion 8 and the second clamping protrusion 7.

[0024] The first slider 24 and the second slider 26 are both provided with a sliding aid, which includes a movable sleeve 35 and a second spring 34. The first slider 24 and the second slider 26 are provided with a horizontally arranged sinking groove, and the movable sleeve 35 is slidably arranged in the sinking groove. One end of the second spring 34 abuts against the first slider 24 or the second slider 26, and the other end is located in the movable sleeve 35. The second spring 34 applies a force to the movable sleeve 35 to abut against the lower template 16. The second spring 34 can play a role in boosting the first slider 24 and the second slider 26 when the upper template 14 and the lower template 16 are opened. After the mold is fully opened, the first slider 24 and the second slider 26 are kept away from the first molding cavity 30 and the second molding cavity 27. When the first slider 24 and the second slider 26 move synchronously with the movable ring 23, relative movement will occur between the two and the lower mold plate 16. In order to avoid direct contact between the second spring 34 and the lower mold plate 16, a movable sleeve 35 is provided. The movable sleeve 35 and the lower mold plate 16 are in planar contact, which can reduce the degree of wear of the relative movement between the two and prevent the second spring 34 from falling from the first slider 24 and the second slider 26.

[0025] The sequential mold opening assembly 15 includes a fixed seat 19, a first driving rod 20, a second driving rod 29, a movable rod 44 and a third spring 43. The fixed seat 19 is fixedly mounted on the upper mold plate 14, and two first through grooves 39 are arranged on the fixed seat 19. The movable rod 44 is horizontally slidably arranged in the fixed seat 19, and a second through groove 40 is arranged on the movable rod 44. One end of the first driving rod 20 is fixed on the gate plate 13, and the other end passes through one of the first through grooves 39. One end of the second driving rod 29 is fixed on the lower mold plate 16, and the other end passes through another first through groove 39 and the second through groove. 40, a first wedge-shaped protrusion 46 is provided at one end of the first driving rod 20, an anti-slip hook 42 is provided at one end of the second driving rod 29, a second wedge-shaped protrusion 41 is provided on the anti-slip hook 42, a third wedge-shaped protrusion 47 and a fourth wedge-shaped protrusion 45 are provided on the movable rod 44, and a third spring 43 is also provided on the inner side of the fixed seat 19, and the third spring 43 applies a force to the movable rod 44 to approach the first driving rod 20. During the mold opening process, the panel 10 remains stationary, and the lower mold plate 16 will move in a direction away from the panel 10, and the first driving rod 20 is between the fixed seat 19 and the movable rod 44. The relative movement of the second driving rod 29 is not restricted, and the second driving rod 29 cannot move relative to the fixing seat 19 when the anti-slip hook 42 hooks the movable rod 44, so that the upper template 14 and the lower template 16 cannot be opened. Therefore, the upper template 14 and the lower template 16 keep synchronous movement, so that the mold between the gate plate 13 and the upper template 14 is opened first, until the injection flow channel 32 is pulled out of the upper template 14, and then the first wedge-shaped protrusion 46 on the first driving rod 20 conflicts with the third wedge-shaped protrusion 47 on the movable rod 44. Due to the resistance to relative movement between the two, the panel 10 and the gate plate 13 are opened. The mold is molded in a manner that the protrusion 36 on the hook needle 33 is separated from the injection molding runner 32, and the injection molding runner 32 is also separated from the sprue plate 13, so that the injection molding runner 32 can fall smoothly. When the mold opening distance between the sprue plate 13 and the panel 10 and the upper mold plate 14 reaches the maximum, the first wedge-shaped protrusion 46 and the third wedge-shaped protrusion 47 move relative to each other, so that the movable rod 44 slides horizontally and compresses the third spring 43, and releases the movable limit between the anti-slip hook head 42 and the movable rod 44, so that the upper mold plate 14 and the lower mold plate 16 can be opened smoothly. This design can ensure the accuracy of sequential actions.

[0026] A discharge assembly is provided on the panel 10, and the discharge assembly includes a hook 33 and a plug 31. One end of the hook 33 is located on the panel 10, and the other end has a protrusion 36 located in the injection channel 32. The plug 31 is threadedly connected to the panel 10 and is used to prevent the hook 33 from detaching from the panel 10. During the injection molding process, the injection channel 32 will wrap the protrusion 36 after cooling, and when the gate plate 13 and the upper mold plate 14 are opened, the injection channel 32 can be pulled out of the upper mold plate 14 and the injection channel 32 can be separated from the first fastener 5 and the second fastener 2.

[0027] Working principle: Before injection molding, the movable mold part and the fixed mold part are first molded together. At this time, the pressure rod 17 will first press the movable ring 23, so that the first spring 37 is compressed, and the first slider 24 and the second slider 26 move synchronously with the movable ring 23. At the same time, the first wedge surface 18 on the fixed block 21 cooperates with the first slider 24 and the second slider 26, and one end of the first slider 24 and the second slider 26 slides toward the direction close to the first molding cavity 30 and the second molding cavity 27. Then the upper mold plate 14 and the lower mold plate 16 are molded together, and then the external injection molding barrel injects the molten plastic raw material into the mold. It is injected from the nozzle sleeve 11 and flows along the injection channel 32 to the first molding cavity 30 and the second molding cavity 27, and then the mold is opened after a period of heat preservation and pressure maintenance. When the mold is opened, the anti-slip hook 42 on the second drive rod 29 will hook the movable rod 44, so that the upper mold 14 and the lower mold 16 remain in the mold closing state, and the gate plate 13 and the upper mold 14 will be opened first, the hook 33 will pull the injection channel 32 out of the upper mold 14, and then the panel 10 and the gate plate 13 will be opened, so that the injection channel 32 can smoothly fall from between the gate plate 13 and the upper mold 14.

[0028] When the nozzle plate 13 is opened to the maximum distance from the panel 10 and the upper mold plate 14, the first driving rod 20 will drive the movable rod 44 to slide horizontally, and release the movable limit of the anti-drop hook 42 and the movable rod 44, so that the second driving rod 29 and the fixed seat 19 can move relative to each other, so that the upper mold plate 14 and the lower mold plate 16 can be opened. When the two are opened, the first spring 37 will drive the movable ring 23 to move in the direction of the upper mold plate 14. At this time, the first slider 24 and the second slider 26 are in a state of conflict with the fixed block 21. At the same time, the first slider 24 and the second slider 26 can keep synchronous movement with the movable ring 23, so that the first buckle The first and second fasteners 5 and 2 are ejected from the first molding cavity 30 and the second molding cavity 27. When the movable ring 23 is restricted by the second limiting bolt 25 and cannot continue to move, the upper mold plate 14 and the lower mold plate 16 continue to open the mold. At this time, the first slider 24 and the second slider 26 are separated from the fixed block 21. Relying on the cooperation between the inclined guide column 22 and the inclined hole 28, the first slider 24 and the second slider 26 are respectively disengaged from the first clamping protrusion 8 and the second clamping protrusion 7, so that the first fastener 5 and the second fastener 2 can be demolded and automatically dropped without designing a separate ejection structure, which simplifies the structure of the molding device and shortens the injection molding cycle.
