Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a processing die equipment for two-color overmolded swimming goggles, which has the advantages that the sprue material of the swimming goggles is cut off when the goggles are demolded, and the cut caused by cutting off the sprue on the swimming goggles is processed, without the need to transfer to other processes to separately process the sprue material, thereby improving the production efficiency of the swimming goggles and eliminating the process of separately processing the sprue material on the swimming goggles, saving the production cost of the swimming goggles, etc. It solves the problem that during the injection molding process of the mold, the hot glue in the hot runner will cool and solidify together with the injection-molded swimming goggles, forming excess sprue material on the injection-molded swimming goggles. After taking out the swimming goggles from the mold, it is necessary to transfer to other processes to separately process the sprue material on the swimming goggles to obtain the final product, which not only reduces the production efficiency of the product but also increases the production cost of the product due to the need to separately process the sprue material through other processes.

[0006] To solve the above technical problem that during the injection molding process of the mold, the hot glue in the hot runner will cool and solidify together with the injection-molded swimming goggles, forming excess sprue material on the injection-molded swimming goggles. After taking out the swimming goggles from the mold, it is necessary to transfer to other processes to separately process the sprue material on the swimming goggles to obtain the final product, which not only reduces the production efficiency of the product but also increases the production cost of the product due to the need to separately process the sprue material through other processes, the present invention provides the following technical solution: A processing die equipment for two-color overmolded swimming goggles, including a mounting seat and an injection mold arranged on the mounting seat.

[0017] Compared with the prior art, the present invention provides a two-color overmolding goggle processing die device, which has the following beneficial effects:

[0018] 1. In this two-color overmolding goggle processing die device, through the setting of the pushing plate and the push knife plate, when the injection molding die opening assembly opens the injection molding die, the driving assembly drives the pushing plate and the push knife plate to move towards each other. During the movement of the pushing plate, the goggle clamp clamps the goggles and takes them away from the injection molding die. When the pushing plate meets the push knife plate, the push knife plate cuts off the sprue material on the goggles through the cutting knife and grinds the cut on the goggles through the filing plate. Thus, the sprue material of the goggles is cut off when the goggles are demolded, and the cut left on the goggles due to the removal of the sprue is processed, without the need to transfer to other processes to separately process the sprue material. Therefore, the production efficiency of the goggles is improved, and the process of separately processing the sprue material on the goggles is eliminated, saving the production cost of the goggles.

[0019] 2. In this two-color overmolding goggle processing die device, through the setting of the material discharging assembly, after the push knife plate completes the processing of the sprue material on the goggles through the cutting knife and the filing plate, the push knife plate presses the top block extending out of the pushing plate through the convex block, triggering the material discharging assembly. The top block extrudes the material discharging plate out of the sliding groove, generating a thrust on the goggles on the goggle clamp. Combining the thrust with the inertia of the goggle clamp itself, the goggles are separated from the clamping of the goggle clamp and fall into the collecting box, automatically completing the discharging, thereby improving the collection efficiency of the finished products and further improving the production efficiency of the goggles.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-8 , a two - color overmolding goggle processing mold device, including a mounting seat 1 and an injection mold 2 arranged on the mounting seat 1. The injection mold 2 includes an upper mold 21 and a lower mold 22. A mold - opening assembly 3 and a driving assembly 4 are further arranged on the mounting seat 1. The mold - opening assembly 3 is fixedly connected to the upper mold 21, and the driving assembly 4 is in transmission cooperation with the mold - opening assembly 3. A pusher plate 5 and a push - knife plate 6 are arranged on the driving assembly 4. When the mold - opening assembly 3 opens the mold, the pusher plate 5 and the push - knife plate 6 are driven by the driving assembly 4 to move relative to each other on the mounting seat 1;

[0031] The pusher plate 5 is provided with a goggle clip 51 and a material discharging assembly 7. The pusher plate 5 clamps the goggles with the rubber coating completed in the injection mold 2 through the goggle clip 51 and conveys them towards the push knife plate 6. A trimming knife 61 is provided at the bottom of the push knife plate 6. When the pusher plate 5 passes by the push knife plate 6 in a staggered manner, the trimming knife 61 cuts off the sprue material on the goggles and triggers the material discharging assembly 7 to push the goggles out of the goggle clip 51.

[0032] Among them, during use, first, the lens is placed into the injection mold 2. When the mold is closed, the mold cavity formed by the upper mold 21 and the lower mold 22 wraps around the position on the outer side of the lens that needs rubber coating. The lens is rubber-coated through the injection mold 2 to form the injection-molded goggles. After the injection molding is completed, the mold opening assembly 3 lifts the upper mold 21 upward to open the injection mold 2. During the mold opening process, the mold opening assembly 3 drives the driving assembly 4 to operate. The driving assembly 4 in operation drives the pusher plate 5 and the push knife plate 6 to move towards each other. At the same time, as the upper mold 21 of the injection mold 2 is opened, the injection-molded goggles on the lower mold 22 of the injection mold 2 are pushed out of the lower mold 22 by the ejector pins in the lower mold 22. At this time, the goggles are connected with the sprue material generated by the mold runner during injection molding. When the pusher plate 5 passes between the separated upper mold 21 and lower mold 22, the pusher plate 5 clamps the goggles on the lower mold 22 through the goggle clip 51 and pushes the goggles out of the injection mold 2 towards the push knife plate 6. When the pusher plate 5 meets the push knife plate 6, the trimming knife 61 on the push knife plate 6 cuts off the sprue material on the goggles. As the pusher plate 5 and the push knife plate 6 continue to move forward, the push knife plate 6 will contact the material discharging assembly 7 on the pusher plate 5, thereby triggering the material discharging assembly 7. The triggered pusher assembly exerts a thrust on the goggles on the goggle clip 51. At the same time, the mold opening assembly 3 lifts the upper mold 21 to the maximum height to complete the mold opening. The mold opening assembly 3 stops moving and no longer drives the driving assembly 4. The goggles slide out of the goggle clip 51 under the action of the thrust and separate from the pusher plate 5 to complete the unloading. Subsequently, the mold opening assembly 3 starts to push the upper mold 21 downward to make the upper mold 21 move towards the lower mold 22 for mold closing, and starts to inject the next goggle. During the mold closing process, the mold opening assembly 3 drives the pusher plate 5 and the push knife plate 6 to move in the opposite direction simultaneously through the driving assembly 4, so that the pusher plate 5 and the push knife plate 6 move towards their original positions. When the push knife plate 6 separates from the material discharging assembly 7, the material discharging assembly 7 returns to the state of waiting to be triggered. When the pusher plate 5 and the push knife plate 6 return to their original positions, the upper mold 21 and the lower mold 22 are in close contact to complete the mold closing, and the next goggle starts to be injection-molded in the injection mold 2.

[0033] Further, a lower die 22 is fixedly installed on the upper surface of one end of the mounting base 1. Four guide posts 11 are arranged on the mounting base 1. The four guide posts 11 are distributed in two groups on both sides of the lower die 22. A fixed seat 12 is fixedly connected to the top end of the guide post 11. A damping spring 111 is sleeved on the lower end of each guide post 11. The lower end of the damping spring 111 is fixedly connected to the mounting base 1. A column 13 is fixedly installed on one side of the mounting base 1. The column 13 is located between a group of guide posts 11 and is shorter than the damping spring 111 during mold closing.

[0034] Further, the driving assembly 4 includes a material pushing screw rod 41, a material pushing guide rod 42, a cutting knife screw rod 43 and a cutting knife guide rod 44. A fixed frame 14, a first end bracket and a second end bracket are fixedly installed on the upper surface of the mounting base 1. The first end bracket, the fixed frame 14, the injection mold 2 and the second end bracket are arranged in sequence. The material pushing screw rod 41 and the material pushing guide rod 42 are both arranged between the first end bracket and the second end bracket, and are located on both sides of the lower die 22 and between the guide posts 11 on both sides. The material pushing screw rod 41 is located on one side of the column 13. The cutting knife screw rod 43 and the cutting knife guide rod 44 are both arranged between the first end bracket and the fixed frame 14. The cutting knife screw rod 43 is on the same side as the material pushing screw rod 41 and is directly above one end of the material pushing screw rod 41.

[0035] Specifically, both ends of the material pushing screw rod 41 are rotatably installed on the first end bracket and the second end bracket through bearings respectively. Both ends of the material pushing guide rod 42 are fixedly installed on the first end bracket and the second end bracket respectively. Both ends of the cutting knife screw rod 43 are rotatably installed on the first end bracket and the fixed frame 14 through bearings respectively. Both ends of the cutting knife guide rod 44 are fixedly installed on the first end bracket and the fixed frame 14 respectively.

[0036] Further, a driving gear 411 is coaxially fixedly connected to one end of the material pushing screw rod 41. The driving gear 411 corresponds to the column 13. Baffles 412 are arranged on both the material pushing screw rod 41 and the material pushing guide rod 42. The baffle 412 is located on the side of the driving gear 411 facing the fixed frame 14. A transmission gear 413 is coaxially fixedly connected to the other end of the material pushing screw rod 41. A driven gear 431 is coaxially fixedly connected to one end of the cutting knife screw rod 43. The driven gear 431 meshes with the transmission gear 413.

[0037] Among them, during mold opening, the driving gear 411 drives the material pushing screw rod 41 to rotate forward, thereby driving the transmission gear 413 at the other end of the material pushing screw rod 41 to rotate in the same direction, so that the transmission gear 413 drives the driven gear 431 meshing with it, making the cutting knife screw rod 43 rotate reversely. During mold closing, the driving gear 411 drives the material pushing screw rod 41 to rotate reversely, thereby driving the transmission gear 413 at the other end of the material pushing screw rod 41 to rotate in the same direction, so that the transmission gear 413 drives the driven gear 431 meshing with it, making the cutting knife screw rod 43 rotate forward.

[0038] Furthermore, link rods 52 are fixedly connected to both sides of the pusher plate 5. A threaded sleeve is provided on one of the link rods 52, and the threaded sleeve is threadedly assembled on the pusher screw rod 41. A sliding sleeve is provided on the other link rod 52, and the sliding sleeve is slidably assembled on the pusher guide rod 42. A sliding groove 53 is formed on one side of the pusher plate 5.

[0039] During the mold opening process, when the pusher screw rod 41 rotates forward, it drives the link rod 52 thereon, causing the link rod 52 to drive the pusher plate 5 to pass through between the upper mold 21 and the lower mold 22 under the guidance of the pusher guide rod 42, so that the pusher plate 5 moves away from the second end bracket towards the pusher blade 6. During the mold closing process, when the pusher screw rod 41 rotates reversely, it drives the link rod 52 thereon, causing the link rod 52 to drive the pusher plate 5 to move towards the second end bracket under the guidance of the pusher guide rod 42, and pass through between the upper mold 21 and the lower mold 22 until it is reset. The baffle 412 will block the continuous movement of the link rod 52 to prevent the link rod 52 from moving excessively.

[0040] Furthermore, one side of the pusher blade 6 is threadedly assembled on the pusher blade screw rod 43, and the other side of the pusher blade 6 is slidably assembled on the pusher blade guide rod 44. A convex block 62 is provided at the bottom of the pusher blade 6, and the convex block 62 is located on both sides of the cutting tool 61. A file plate 611 is provided at the end of the cutting tool 61, and the file plate 611 is located behind the cutting head of the cutting tool 61.

[0041] During mold opening, the pusher blade screw rod 43 rotates reversely, driving the pusher blade 6 to move towards the pusher plate 5. After the cutting head of the cutting tool 61 cuts off the sprue material, as the pusher blade 6 continues to move, the file plate 611 behind the cutting head passes through the cut of the sprue material on the swimming goggles, grinding the cut of the sprue material on the swimming goggles flat. After the file plate 611 passes through, the convex block 62 at the bottom of the pusher blade 6 starts to contact the top block 73, and as the pusher blade 6 moves, it presses the top block 73 downward. When the protruding top block 73 is completely pressed into the sliding groove 53, the mold opening is completed. During mold closing, the pusher blade 6 starts to move back, and the convex block 62 ends pressing on the top block 73.

[0042] Furthermore, the material discharging assembly 7 includes a material discharging plate 71 and a top block 73. The material discharging plate 71 is slidably installed in the sliding groove 53. A return spring 72 is fixedly connected between one side of the material discharging plate 71 and the inner wall of the sliding groove 53. Top blocks 73 are provided at both ends of the material discharging plate 71. A support spring 74 is fixedly connected between the lower side of the top block 73 and the bottom of the sliding groove 53. The upper side of the top block 73 slidably penetrates through the top of the sliding groove 53 and protrudes from the upper side of the pusher plate 5, corresponding to the position of the convex block 62.

[0043] Among them, the upper surface of the top block 73 is planar, and one side of the top block 73 close to the convex block 62 is set as a triangular block standing upright. At both ends of the side where the stripping plate 71 is connected to the return spring 72, there are protruding extrusion blocks. Under the action of the return spring 72, the extrusion blocks can always be in contact with the lower inclined surface of the corresponding triangular block;

[0044] After the gate material on the swimming goggles is cut off and the cut is ground flat, as the push knife plate 6 continues to move, the convex block 62 first contacts the upper inclined surface of the triangular block on the side of the top block 73, and then contacts the upper surface of the top block 73. At this time, the upper end of the top block 73 is pressed by the convex block 62 into the sliding groove 53, compressing the support spring 74. The top block 73 drives the triangular block to descend, so that its lower inclined surface acts on the extrusion block, and the extrusion block slides along the lower inclined surface of the triangular block, causing the extrusion block to drive the stripping plate 71 to move, extruding the stripping plate 71 out of the sliding groove 53. The stripping plate 71 extruded out of the sliding groove 53 by the top block 73 exerts a thrust on the swimming goggles on the swimming goggles clip 51 and stretches the return spring 72. The swimming goggles are separated from the swimming goggles clip 51 under the action of the thrust to realize the unloading of the swimming goggles clip 51. When closing the mold, when the convex block 62 finishes pressing the top block 73, the compressed support spring 74 pushes the top block 73 out again to reset the top block 73. At the same time as the top block 73 is reset, the stretched return spring 72 begins to contract, pulling the stripping plate 71 back into the sliding groove 53 to reset the pushing plate 5.

[0045] Further, the mold opening assembly 3 includes a hydraulic cylinder 31 and a connecting plate 32. The hydraulic cylinder 31 is arranged on the fixed seat 12. The connecting plate 32 slides through the guiding column 11 and is located between the fixed seat 12 and the lower mold 22. The output shaft of the hydraulic cylinder 31 is fixedly connected to the upper side of the connecting plate 32, and the lower side of the connecting plate 32 is fixedly connected to the upper side of the upper mold 21.

[0046] Among them, when opening the mold, the hydraulic cylinder lifts the connecting plate 32 through the output shaft, so that the connecting plate 32 leaves the damping spring 111 under the guidance of the guiding column 11 and drives the upper mold 21 of the injection mold 2 to move upward, separating the upper mold 21 of the injection mold 2 from the lower mold 22. When closing the mold, the hydraulic cylinder lowers the connecting plate 32 through the output shaft, so that the connecting plate 32 drives the upper mold 21 to move downward under the guidance of the guiding column 11, bringing the upper mold 21 of the injection mold 2 into contact with the lower mold 22 and pressing the upper mold 21 and the lower mold 22 tightly. During the process of closing the mold, the bottom of the connecting plate 32 will abut against the damping spring 111, and the damping spring 111 thus buffers the impact force generated when the upper mold 21 and the lower mold 22 are closed, preventing the injection mold 2 from being damaged.

[0047] Further, a driving rack 33 is arranged on one side of the connecting plate 32. The upper end of the driving rack 33 is fixedly connected to the connecting plate 32. The driving rack 33 is slidably matched with the inner wall of the column 13, and the lower end of the driving rack 33 slides through the surface of the mounting seat 1. The driving rack 33 meshes with the driving gear 411.

[0048] During the process of mold opening or closing, the connecting plate 32 drives the driving rack 33 to move synchronously within the column 13, causing the driving rack 33 to drive the driving gear 411 meshing with it to rotate. During the movement of the driving rack 33, the column 13 guides the driving rack 33 to prevent the driving rack 33 from shifting and disengaging from the driving gear 411.

[0049] Furthermore, a material taking port 15 is formed at one end of the mounting seat 1. The material taking port 15 is located between the pushing knife lead screw 43 and the pushing knife guide rod 44. A collecting box 8 is slidably mounted at the bottom of the material taking port 15. A detachable separating net 81 is arranged inside the collecting box 8. The separating net 81 is inclined from the side close to the lower mold 22 to the side away from the lower mold 22.

[0050] Among them, the sprue cut by the cutting knife 61 and the debris filed by the filing plate 611, together with the goggles, fall into the lower collecting box 8. The sprue and the debris fall into the collecting box 8 through the separating net 81, while the goggles will remain on the separating net 81 and slide to the bottom end of the separating net 81, facilitating the worker to take out the goggles from the collecting box 8. After the collecting box 8 is filled with the waste composed of the sprue and the debris, the collecting box 8 is taken out from under the mounting seat 1. After cleaning the waste in the collecting box 8, the collecting box 8 is reinstalled under the mounting seat 1.

[0051] Working principle: When in use, first place the lens into the injection mold 2. When the mold is closed, the mold cavity formed by the upper mold 21 and the lower mold 22 wraps around the position on the outer side of the lens that needs to be coated with glue. The lens is coated with glue through the injection mold 2 to form the injection-molded goggles. After the injection molding is completed, the mold opening assembly 3 lifts the upper mold 21 upward to open the injection mold 2. During the mold opening process, the hydraulic cylinder lifts the connecting plate 32 through the output shaft, causing the connecting plate 32 to drive the upper mold 21 of the injection mold 2 to move upward under the guidance of the guiding column 11, separating the upper mold 21 of the injection mold 2 from the lower mold 22. At the same time, the connecting plate 32 drives the driving rack 33 to move synchronously within the column 13, causing the driving rack 33 to drive the driving gear 411 meshing with it. The driving gear 411 drives the pushing lead screw 41 to rotate forward, thereby driving the transmission gear 413 at the other end of the pushing lead screw 41 to rotate in the same direction, causing the transmission gear 413 to drive the driven gear 431 meshing with it, making the pushing knife lead screw 43 rotate reversely, thereby driving the pushing plate 5 and the pushing knife plate 6 to move towards each other. During the movement of the driving rack 33, the column 13 guides the driving rack 33 to prevent the driving rack 33 from shifting and disengaging from the driving gear 411;

[0052] As the upper mold 21 of the injection mold 2 is opened, the goggles that have been injection-molded on the lower mold 22 of the injection mold 2 are ejected from the lower mold 22 by the ejector pins in the lower mold 22. At this time, the goggles are connected with the sprue material generated by the mold runner during injection molding. When the push plate 5 passes between the separated upper mold 21 and lower mold 22, the push plate 5 clamps the goggles on the lower mold 22 through the goggle clamp 51 and pushes the goggles out of the injection mold 2 towards the push knife plate 6. When the push plate 5 meets the push knife plate 6, the cutting knife 61 on the push knife plate 6 cuts off the sprue material on the goggles. As the push plate 5 and the push knife plate 6 continue to move forward, the file plate 611 behind the knife head passes over the cut of the sprue material on the goggles and grinds the cut of the sprue material on the goggles flat. The push knife plate 6 will contact the ejection component 7 on the push plate 5, thus triggering the ejection component 7;

[0053] During this process, after the file plate 611 passes, the convex block 62 at the bottom of the push knife plate 6 starts to contact the top block 73. As the push knife plate 6 continues to move, the convex block 62 first contacts the upper inclined surface of the triangular block on the side of the top block 73 and then contacts the upper surface of the top block 73. At this time, the upper end of the top block 73 is pressed by the convex block 62 into the sliding groove 53, compressing the support spring 74, and extruding the ejection plate 71 out of the sliding groove 53 through the convex strip. The ejection plate 71 that is extruded from the sliding groove 53 by the top block 73 applies a thrust to the goggles on the goggle clamp 51 and stretches the return spring 72. The goggles are separated from the goggle clamp 51 under the action of the thrust to achieve the unloading of the goggle clamp 51. When the protruding top block 73 is completely pressed into the sliding groove 53, the mold opening component 3 raises the upper mold 21 to the maximum height to complete the mold opening. The mold opening component 3 stops moving and no longer drives the driving component 4. At this time, the sprue material cut by the cutting knife 61 and the debris filed by the file plate 611 together with the goggles fall into the lower collection box 8. The sprue material and the debris fall into the collection box 8 through the separation net 81, while the goggles will remain on the separation net 81 and slide to the bottom end of the separation net 81, facilitating the worker to take out the goggles from the collection box 8. After the collection box 8 is filled with the waste composed of the sprue material and the debris, the collection box 8 is taken out from under the mounting seat 1. After cleaning the waste in the collection box 8, the collection box 8 is reinstalled under the mounting seat 1;

[0054] Subsequently, the mold opening assembly 3 starts to push the upper mold 21 downward, causing the upper mold 21 to move downward towards the lower mold 22 for mold closing. During this process, the bottom of the connecting plate 32 will abut against the damping spring 111, and the damping spring 111 thus buffers the impact force generated when the upper mold 21 and the lower mold 22 are closed, preventing the injection mold 2 from being damaged. At the same time, the connecting plate 32 drives the driving rack 33 to move synchronously within the column 13, causing the driving rack 33 to drive the driving gear 411 meshing with it. The driving gear 411 drives the feeding screw rod 41 to rotate reversely, thereby driving the transmission gear 413 at the other end of the feeding screw rod 41 to rotate in the same direction, causing the transmission gear 413 to drive the driven gear 431 meshing with it, causing the pushing knife screw rod 43 to rotate forward, and causing the feeding plate 5 and the pushing knife plate 6 to move towards their respective original positions. When the pushing knife plate 6 separates from the material discharging assembly 7, the convex block 62 ends the pressing on the top block 73, and the compressed support spring 74 pushes the top block 73 out again, causing the top block 73 to reset. At the same time when the top block 73 resets, the stretched reset spring 72 starts to contract, pulling the material discharging plate 71 back into the sliding groove 53, causing the feeding plate 5 to reset. When the feeding plate 5 and the pushing knife plate 6 return to their original positions, the upper mold 21 and the lower mold 22 tightly abut to complete mold closing, and the next swimming goggle starts to be injection molded within the injection mold 2.
