Description

Technical Field

[0001] This invention relates to the field of all-plastic spray gun processing technology, specifically to an injection molding device for all-plastic spray gun processing. Background Technology

[0002] All-plastic spray guns are widely used in spraying, cleaning, gardening and other fields. In the production of all-plastic spray guns, injection molding machines are usually used to injection mold the all-plastic spray guns. During the injection molding process, in order to facilitate demolding, a release agent needs to be sprayed horizontally into the mold groove through the nozzle, so that the finished product can be easily taken out from the mold groove after molding.

[0003] In spray gun injection molding, when the mold cavity includes a gun head, a raised ring, and a gun body, and the diameter of the raised ring is relatively large compared to the gun head and body, the traditional horizontal spraying method, where the spray nozzle coats the mold cavity from top to bottom, makes it difficult to effectively coat the upper surface of the raised ring with the release agent. This leads to the raised ring sticking to the mold during subsequent demolding, affecting the demolding effect and thus reducing the quality of the injection molding. Summary of the Invention

[0004] This invention provides an injection molding device for processing all-plastic spray guns. By rotating the nozzle, the angle of the nozzle is adjusted so that when the nozzle is spraying the upper surface of the convex ring of the mold groove, the nozzle can be kept tilted upward, thereby facilitating the spraying of the release agent onto the upper surface of the convex ring.

The second trajectory groove includes a third vertical part, a second right-moving part, a second left-moving part, a third right-moving part and a fourth vertical part that are connected together.

[0011] As an optional embodiment of the injection molding device for processing all-plastic spray guns according to the present invention, a first limiting ball is fixed at the end of the core rod, and a first limiting groove is provided inside the moving block for the first limiting ball to slide.

[0012] As an optional embodiment of the injection molding device for processing all-plastic spray guns according to the present invention, a sleeve rod is slidably disposed on the movable seat, the sleeve rod is slidably sleeved on the outside of the core rod, one end of the sleeve rod is slidably connected to the mounting seat, and the other end of the sleeve rod is slidably disposed in the first groove.

The third trajectory groove includes a fifth vertical part, a first extension part, a second extension part and a sixth vertical part.

[0014] As an optional embodiment of the injection molding device for processing all-plastic spray guns according to the present invention, a reciprocating screw is rotatably provided on the adjusting seat, the moving seat is threadedly connected to the reciprocating screw, a first servo motor is installed on the top of the adjusting seat, and the output end of the first servo motor is fixed to the reciprocating screw.

[0015] As an optional embodiment of the injection molding device for processing all-plastic spray guns according to the present invention, a positioning seat is fixed on the outer surface of the injection molding machine body, a servo electric cylinder is fixed on the positioning seat, a support plate is fixed on the output end of the servo electric cylinder, a rotating rod is rotatably arranged on the support plate, the top of the rotating rod is fixed to the adjustment seat, a second servo motor is fixed on the bottom of the support plate, and the output end of the second servo motor is fixed to the rotating rod.

[0016] The present invention has the following beneficial effects:

[0017] 1. The injection molding device for processing all-plastic spray guns uses a movable seat to drive the core rod downwards, causing the first sliding protrusion to slide along the first vertical part of the first track groove into the first right-moving part and move to the right. This, in turn, drives the core rod, the movable block, and the push rod to move to the right, pushing the rotating rod and the rotating shaft to rotate counterclockwise, thus tilting the nozzle so that it can spray the upper surface of the convex ring at an angle upwards. At the same time, the first sliding protrusion continues to slide along the first right-moving part, causing the nozzle to rotate counterclockwise continuously, which prolongs the spraying time on the upper surface of the convex ring, effectively avoiding the situation where the release agent is not sprayed in place in this area, which is conducive to improving the subsequent demolding effect and thus improving the injection molding quality.

[0018] 2. In this injection molding device for processing all-plastic spray gun, when the nozzle moves downward to the convex ring, the mounting base drives the slide rod to move down along the second slide groove. The slide rod drives the second sliding protrusion to slide along the second track groove, so that the nozzle can perform left and right reciprocating motion. When the nozzle sprays the upper surface of the convex ring at an angle upward, its spraying range is effectively increased, ensuring full coverage of the upper surface of the convex ring and completely avoiding the generation of spraying dead corners, thereby further significantly improving the demolding effect.

[0019] 3. In the injection molding device for processing the all-plastic spray gun, when the nozzle is tilted and reciprocating left and right to spray the convex ring, the reciprocating screw drives the moving seat to move vertically downward. The moving seat synchronously drives the sleeve rod downward. The sleeve rod slides along the first sliding groove and drives the third sliding protrusion to slide along the third track groove. Since the downward movement speed of the moving seat and the sleeve rod is the same, the downward movement speed of the moving seat and the mounting seat is consistent. At the same time, the sliding track length of the first extension and the second extension is greater than the straight downward length. This results in the mounting seat and the nozzle taking a longer time to travel this distance, thereby extending the spraying time of the nozzle on the upper surface of the convex ring and ultimately further improving the spraying effect on the upper surface of the convex ring.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1, please refer to Figures 1-12 An injection molding device for processing all-plastic spray guns includes an injection molding machine body 1, a mold 2 for molding is provided on the injection molding machine body 1, a mold groove 3 is provided on the mold 2, and a horizontally movable adjustment seat 4 is provided on one side of the injection molding machine body 1. A nozzle 5 for spraying release agent onto the mold groove 3 is provided on the adjustment seat 4.

[0035] A movable seat 6 that can be raised and lowered is slidably arranged on the adjusting seat 4. A mounting seat 7 that is raised and lowered synchronously with the movable seat 6 is arranged on one side of the adjusting seat 4. A rotating shaft 8 is elastically arranged on the mounting seat 7. The nozzle 5 is fixed on the rotating shaft 8. A moving groove 9 is opened inside the mounting seat 7. A moving block 10 is slidably arranged in the moving groove 9. A push rod 11 is fixed on the surface of the moving block 10. A rotating rod 12 is fixed on the circumference of the rotating shaft 8. The nozzle 5 adjusts its angle by pushing the push rod 11 against the rotating rod 12.

[0036] A core rod 13 is slidably mounted on the movable seat 6. The end of the core rod 13 is connected to the movable block 10. A first sliding groove 14 is provided on the surface of the adjusting seat 4. The core rod 13 drives the movable block 10 to slide in the movable groove 9 by sliding along the first sliding groove 14.

[0037] The end of the core rod 13 is fixed with a first sliding protrusion 15. The inner wall of the first groove 14 is provided with a first track groove 16 for the first sliding protrusion 15 to slide. The first track groove 16 includes a first vertical part 161, a first right-moving part 162, a first left-moving part 163 and a second vertical part 164 that are connected together.

[0038] A reciprocating lead screw 28 is rotatably mounted on the adjusting seat 4, and the moving seat 6 is threadedly connected to the reciprocating lead screw 28. A first servo motor 29 is mounted on the top of the adjusting seat 4, and the output end of the first servo motor 29 is fixed to the reciprocating lead screw 28.

[0039] A positioning seat 30 is fixed on the outer surface of the injection molding machine body 1. A servo electric cylinder 31 is fixed on the positioning seat 30. A support plate 32 is fixed to the output end of the servo electric cylinder 31. A rotating rod 33 is rotatably mounted on the support plate 32. The top of the rotating rod 33 is fixed to the adjusting seat 4. A second servo motor 34 is fixed to the bottom of the support plate 32. The output end of the second servo motor 34 is fixed to the rotating rod 33.

[0040] In this technical solution, before injection molding, the support plate 32 is moved by the servo cylinder 31, and the support plate 32 moves the adjusting seat 4 and the nozzle 5. The nozzle 5 is moved to the position of the mold 2, and the release agent is sprayed into the mold groove 3 through the nozzle 5. Then, the first servo motor 29 drives the reciprocating screw 28 to rotate, and the reciprocating screw 28 drives the moving seat 6 to move from top to bottom, so that the moving seat 6 drives the nozzle 5 to spray the mold groove 3 from top to bottom until the spraying is completed. The nozzle 5 is then reset, and the injection molding machine body 1 performs mold closing processing, injects material into the mold groove 3, waits for cooling and molding, and then opens the mold to remove the material, completing the injection molding process of the spray gun.

[0041] In order to facilitate the spraying of release agent on the mold grooves 3 of the two molds 2, the second servo motor 34 drives the support plate 32 to rotate 180°, and the support plate 32 drives the spray head 5 to rotate 180°, so that the spray head 5 can spray the mold groove 3 of the other mold 2, thereby completing the spraying treatment of the mold grooves 3 of the two molds 2.

[0042] When customizing the spray gun, to enhance aesthetics, it's necessary to design protruding ring-like structures at the nozzle. This allows for the creation of unique designs on these rings, attracting customers and increasing economic value. Therefore, during the casting of the model groove 3, which includes the nozzle head 301, protruding ring 302, and nozzle body 303, the protruding ring 302 has a larger diameter than the nozzle head 301 and nozzle body 303. When the nozzle 5 sprays the model groove 3 from top to bottom, the upper surface of the protruding ring 302 is not easily reached by the nozzle 5. Consequently, during demolding, the upper surface of the protruding ring 302 is prone to sticking to the mold, affecting the demolding effect. To address this issue, when the nozzle 5 sprays the protruding ring 302 of the model groove 3 from top to bottom, as... Figure 7 and Figure 8 As shown, the movable seat 6 drives the core rod 13 to move downward along the first sliding groove 14. The core rod 13 drives the first sliding protrusion 15 to slide downward along the first track groove 16. The first sliding protrusion 15 slides from the first vertical part 161 to the first right-moving part 162 and slides along the first right-moving part 162, causing the first sliding protrusion 15 to move to the right. The rightward movement of the first sliding protrusion 15 drives the core rod 13 to move to the right relative to the movable seat 6. The rightward movement of the core rod 13 pushes the movable block 10 to move to the right within the movable groove 9. The movable block 10 drives the push rod 11 to move to the right, causing the push rod 11 to push the rotating rod 12 to rotate counterclockwise. The rotating rod 12 drives the rotating shaft 8 to rotate counterclockwise. The rotating shaft 8 drives the nozzle 5 to rotate counterclockwise, so that the nozzle 5 can tilt when passing the convex ring 302, so that the nozzle 5 can spray the upper surface of the convex ring 302 at an angle upward. In addition, when the nozzle 5 moves downward, it slides along the first right-moving part 162 through the first sliding protrusion 15, so that the nozzle 5 can continue to rotate counterclockwise, so that the spraying angle of the nozzle 5 is always spraying towards the upper surface of the convex ring 302, thereby increasing the time to spray onto the upper surface of the convex ring 302, thus effectively avoiding the situation where the mold release agent cannot be sprayed onto the upper surface of the convex ring 302, which is conducive to improving the subsequent demolding effect and thus improving the injection molding quality.

[0043] A torsion spring 37 is provided between the rotating shaft 8 and the mounting base 7. When the rotating shaft 8 rotates counterclockwise, the torsion spring 37 stores force. When the first sliding protrusion 15 slides along the first left-moving part 163, the core rod 13 moves to the left to reset. The core rod 13 pulls the moving block 10 and the push rod 11 to reset. The rotating rod 12 loses the resistance of the push rod 11. At this time, the torsion spring 37 releases force, causing the rotating shaft 8 to rotate clockwise to reset, thereby driving the nozzle 5 to reset to the horizontal position. Finally, the first sliding protrusion 15 slides along the second vertical part 164, so that the nozzle 5 continues to maintain a horizontal state for spraying.

[0044] In this technical solution, both the injection molding machine body 1 and the nozzle 5 are existing technologies, which can complete the injection molding process of the spray gun and the spraying of the release agent. They are not the innovation of this application and will not be described in detail.

[0045] In Example 2, when the nozzle 5 is tilted upwards to spray the upper surface of the convex ring 302, since the width of the convex ring 302 is larger than that of the gun head 301 and the gun body 303, the spraying range of the nozzle 5 cannot be too large at the beginning to avoid wasting the release agent. Therefore, when the nozzle 5 sprays onto the upper surface of the convex ring 302, there may be insufficient spraying of the upper surface of the convex ring 302, resulting in spraying dead corners. To address this problem, this example is an improvement based on Example 1. For details, please refer to Example 1. Figures 1-12 The outer surface of the mounting base 7 is fixed with a slide rod 17, the outer surface of the adjusting base 4 is fixed with an L-shaped rod 18, the end of the L-shaped rod 18 is fixed with a vertical rod 19, and the surface of the vertical rod 19 is provided with a second sliding groove 20 for the slide rod 17 to slide.

[0046] The end of the slide bar 17 is fixed with a second sliding protrusion 21. The inner wall of the second slide groove 20 is provided with a second track groove 22 for the second sliding protrusion 21 to slide. The second track groove 22 includes a third vertical part 221, a second right-moving part 222, a second left-moving part 223, a third right-moving part 224 and a fourth vertical part 225 that are connected together.

[0047] The end of the core rod 13 is fixed with a first limiting ball 23, and the inside of the moving block 10 is provided with a first limiting groove 24 for the first limiting ball 23 to slide.

[0048] In this technical solution, when the nozzle 5 moves downward to the convex ring 302, the mounting base 7 moves downward, causing the slide rod 17 to move downward along the second slide groove 20. The slide rod 17 causes the second sliding protrusion 21 to slide along the second track groove 22, so that the second sliding protrusion 21 slides from the third vertical part 221 to the second right-moving part 222 and slides along the second right-moving part 222. Figure 11As shown, the second sliding protrusion 21 causes the slide rod 17 to move to the right, the slide rod 17 causes the mounting base 7 to move to the right, and the mounting base 7 causes the nozzle 5 to move to the right. Then, the second sliding protrusion 21 slides along half of the second left-moving portion 223, causing the second sliding protrusion 21 to move the slide rod 17 to the left and reset, causing the nozzle 5 to move to the left and reset. Then, the second sliding protrusion 21 continues to slide along the other half of the second left-moving portion 223, causing the second sliding protrusion 21 to move the slide rod 17 to continue moving to the left, and the slide rod 17 causes the mounting base 7 to continue moving to the left. This causes the nozzle 5 to continue moving to the left. Then, the second sliding protrusion 21 slides along the third rightward movement part 224. The second sliding protrusion 21 drives the slide rod 17 to move to the right and reset, so that the nozzle 5 resets to the initial position again. Through the above process, when the nozzle 5 is tilted upward to spray the upper surface of the convex ring 302, by driving the nozzle 5 to move back and forth left and right, the spraying range of the nozzle 5 is increased, so that the nozzle 5 can fully spray the upper surface of the convex ring 302, thereby avoiding the problem of spraying dead corners and further improving the demolding effect.

[0049] In this technical solution, when the mounting base 7 reciprocates left and right, the core rod 13 drives the first limiting ball 23 to slide left and right along the first limiting slide groove 24, thereby avoiding jamming. The first limiting ball 23 can only slide left and right along the first limiting slide groove 24 and will not slide out from inside the first limiting slide groove 24, so that the core rod 13 can drive the moving block 10 to move along the moving groove 9.

[0050] In Example 3, when the spray nozzle 5 sprays the upper surface of the convex ring 302 from left to right, the spray nozzle 5 moves from top to bottom with the moving seat 6. Since the downward movement speed of the moving seat 6 remains constant, the spray nozzle 5 needs to be reset after tilting, resulting in a shorter time for the spray nozzle 5 to spray onto the upper surface of the convex ring 302, thereby reducing the effectiveness of the release agent. To address this problem, this example is an improvement based on Example 2. For details, please refer to Example 2. Figures 1-12 A sleeve rod 25 is slidably disposed on the movable seat 6. The sleeve rod 25 is slidably sleeved on the outside of the core rod 13. One end of the sleeve rod 25 is slidably connected to the mounting seat 7, and the other end of the sleeve rod 25 is slidably disposed in the first slide groove 14.

[0051] The end of the sleeve rod 25 is fixed with a third sliding protrusion 26, and a third track groove 27 is provided in the first slide groove 14. The third track groove 27 includes a fifth vertical part 271, a first extension part 272, a second extension part 273 and a sixth vertical part 274.

[0052] In this technical solution, during the process of the nozzle 5 tilting and reciprocating spraying the convex ring 302, the reciprocating screw 28 drives the moving seat 6 to move vertically downwards, and the moving seat 6 drives the sleeve 25 to move downwards synchronously, so that the sleeve 25 slides along the first sliding groove 14, and the sleeve 25 drives the third sliding protrusion 26 to slide along the third track groove 27. Figure 6 and Figure 7 As shown, the third sliding protrusion 26 slides from the fifth vertical portion 271 to the first extension portion 272 and slides along the first extension portion 272, causing the third sliding protrusion 26 to drive the sleeve rod 25 to move to the right. The sleeve rod 25 pushes the mounting base 7 to move to the right, and the mounting base 7 drives the nozzle 5 to move closer to the convex ring portion 302. Then, the third sliding protrusion 26 slides along the second extension portion 273, causing the third sliding protrusion 26 to drive the sleeve rod 25 to move to the left. The sleeve rod 25 drives the mounting base 7 to move to the left, causing the nozzle 5 to return to its original position. Through the above process, when the third sliding protrusion 26 slides along the first extension portion 272 and the second extension portion 273... During the process, the movable seat 6 moves downward in a straight line, while the mounting seat 7 and the nozzle 5 move downward along the trajectory of the first extension 272 and the second extension 273. Since the movable seat 6 and the sleeve rod 25 move downward at the same speed, the movable seat 6 and the mounting seat 7 move downward at the same speed. Moreover, the length of the trajectory along the first extension 272 and the second extension 273 is greater than the length of the straight downward movement. Therefore, the mounting seat 7 and the nozzle 5 travel this distance for a longer period of time, which further extends the spraying time of the nozzle 5 on the upper surface of the convex ring 302, thereby further improving the spraying effect on the upper surface of the convex ring 302.

[0053] In this technical solution, the core rod 13 is slidably disposed inside the sleeve rod 25, such as Figure 7 As shown, the distance that the first right-moving part 162 moves to the right is greater than the distance that the first extension part 272 moves to the right, so that when the sleeve rod 25 moves to the right and drives the mounting base 7 to move to the right, the core rod 13 can continue to move to the right relative to the sleeve rod 25, thereby enabling the core rod 13 to push the moving block 10 to move to the right along the moving groove 9, so that the nozzle 5 can rotate normally and the movements of the two do not affect each other.

[0054] In addition, a T-shaped block 35 is fixed to the end of the sleeve rod 25, and a second limiting groove 36 is provided on the surface of the mounting base 7. The T-shaped block 35 can only slide horizontally along the second limiting groove 36 and will not slide out from inside the second limiting groove 36. This allows the T-shaped block 35 to slide along the second limiting groove 36 when the mounting base 7 is reciprocating left and right, thereby avoiding jamming. Furthermore, the T-shaped block 35 will not slide out from inside the second limiting groove 36, so that the sleeve rod 25 can drive the mounting base 7 to move synchronously when it is reciprocating left and right.

[0055] like Figure 12As shown, the L-shaped rod 18 includes a first support rod 181 and a second support rod 182. The first support rod 181 has a storage groove 183 inside. An inner rod 184 is fixed on the second support rod 182 and is slidably disposed in the storage groove 183. The first support rod 181 is fixed to the adjusting seat 4, and the second support rod 182 is fixed to the vertical rod 19. When the sleeve rod 25 drives the mounting seat 7 to move, the inner rod 184 moves inside the storage groove 183, so that the L-shaped rod 18 can extend and retract, thereby ensuring that the slide rod 17 can slide stably along the second slide groove 20.
