Description

Technical Field

[0001] The utility model relates to the technical field of audio pipe fitting processing, in particular to a special mold for audio pipe fittings. Background Technique

[0002] The audio air duct is an important part of the audio system. Its main function is to effectively transmit the sound output by the sound source (such as a speaker) into the air, thereby enhancing the audio effect. The audio air duct can ensure that the sound is smoothly transmitted from the speaker, reducing the attenuation and distortion of the sound. Through reasonable air duct design, the frequency response characteristics of the sound can be improved, making the sound quality clearer and more natural. Some specially designed air ducts also have a certain sound absorption function, which can reduce the noise interference in the environment.

[0003] At present, the structure of the straight pipe is simple and the sound transmission is direct. It is suitable for occasions with a large space, and most of the straight pipes are made of PVC material. Therefore, when processing air ducts at present, air duct injection molds are generally used.

[0004] However, for the special mold for audio pipe fittings at present, when demolding the injection-molded audio air duct, after the upper mold and the lower mold or the left mold and the right mold are opened, then the jacking mechanism in the mold is started to jack out the air duct forming part for demolding. There is an interval during the demolding process, and the demolding time is long. Demolding cannot be carried out during the process of opening the mold, and the processing efficiency needs to be improved. Content of the Utility Model

[0005] The purpose of the utility model is to provide a special mold for audio pipe fittings, which has the effect of directly demolding the formed product when the mold is opened, saves the demolding time, and improves the processing efficiency of the audio air duct.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A special mold for audio pipe fittings, including four support rods. Two left-right distributed fixing plates are movably sleeved on the outer side walls of the four support rods. A first moving seat and a second moving seat are respectively installed on the opposite sides of the two fixing plates. A right mold is embedded and installed on the outer side wall of the second moving seat. A baffle plate is arranged between the first moving seat and the second moving seat. A first threaded cylinder is penetrated and movably installed on the outer side wall of the first moving seat. A screw rod is movably connected to the inner side wall of the first threaded cylinder through a thread. One end of the screw rod penetrates through the fixing plate on the left side and extends to the outside of the fixing plate on the left side. An installation hole is penetrated and opened on the outer side wall of the first moving seat. A first gear fixedly sleeved on the outer side wall of the first threaded cylinder is arranged inside the installation hole. A slot hole communicated with the installation hole is arranged between the first moving seat and the fixing plate on the left side;

[0007] A second threaded cylinder is installed at the right end inside the installation hole. A moving rod is movably connected to the inner side wall of the second threaded cylinder through threads. A third gear meshed with the first gear is fixedly sleeved on the outer side wall of the moving rod. A left mold is installed at the right end of the moving rod.

[0008] Sliding plates are installed on the upper and lower end faces of the second moving seat. Sliding blocks are installed at the opposite ends of the two sliding plates. The outer side walls of the two sliding blocks are slidably connected to sliding frames installed on the upper and lower end faces of the first moving seat. Magnetic blocks are embedded on the opposite sides of the sliding frames and the limit blocks.

[0009] In order to achieve the purpose of rotating the first gear, as an optimization of a special mold for audio pipe fittings of the present utility model, a motor is installed on the front end face of the first moving seat through a bracket. The output end of the motor is installed with a second gear meshed with the first gear.

[0010] In order to facilitate the movement of the baffle along the screw rod, as an optimization of a special mold for audio pipe fittings of the present utility model, through holes are formed in the outer wall side of the baffle. The other end of the screw rod passes through the through hole and is slidably connected to the through hole. The other end of the screw rod is movably connected to the second moving seat through a rotating shaft.

[0011] In order to facilitate the second threaded cylinder to move into the inside of the sliding hole, as an optimization of a special mold for audio pipe fittings of the present utility model, a sliding hole is formed through the outer side wall of the baffle. The outer side wall of the sliding hole is slidably connected to the outer side wall of the second threaded cylinder.

[0012] In order to facilitate the limitation of the baffle, as an optimization of a special mold for audio pipe fittings of the present utility model, limit blocks respectively slidably connected to the two sliding plates are installed on the upper and lower end faces of the baffle.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] When the present utility model is used, when injecting the air duct of the audio, by starting the motor, the second gear rotates to drive the first gear to rotate, prompting the first gear to drive the first threaded cylinder to rotate, thereby driving the first moving seat to move towards the second moving seat. When the first moving seat contacts the baffle during the movement, the sliding frame can be adsorbed on the limit block and move together with the baffle. At the same time, the right end of the second threaded cylinder can move to the port at the right end of the sliding hole, and when the first gear rotates, it can drive the third gear to rotate, enabling the third gear to drive the moving rod to rotate, prompting the moving rod to rotate and move along the second threaded cylinder. Thus, when the first moving seat, the baffle, and the second moving seat are combined together, the moving rod can push the left mold to move into the right mold, and then the injection pipe can inject the hot-melt plastic into the right mold to form the air duct of the audio.

[0015] After the injection molding is completed and demolding is carried out, by restarting the motor again, the second gear drives the first gear to rotate in the reverse direction, so that the first moving seat moves to the left. Since the sliding frame and the limiting block are adsorbed together, when the first moving seat moves to the left, it can drive the baffle plate to move. When the slider contacts the limiting block, the slider can play a role in limiting the limiting block and prevent the baffle plate from moving further. At this time, the rotation of the first gear can drive the third gear to rotate in the reverse direction, prompting the moving rod to drive the left mold to move into the slot hole (in-situ), so as to demold the formed air duct wrapped around the outer wall of the left mold, achieving the effect of directly demolding the formed product when the mold is opened, saving demolding time and improving the processing efficiency of the audio air duct.

Detailed Embodiment

[0020] Please refer to Figures 1 to 3, a special mold for pipe fittings used in audio equipment, including four support rods 1. Two left-right distributed fixing plates 101 are movably sleeved on the outer side walls of the four support rods 1. A first moving seat 2 and a second moving seat 3 are respectively installed on the opposite sides of the two fixing plates 101. A right mold 301 is embedded and installed on the outer side wall of the second moving seat 3. A material blocking plate 4 is arranged between the first moving seat 2 and the second moving seat 3. A first threaded cylinder 402 penetrates and is movably installed on the outer side wall of the first moving seat 2. A screw rod 5 is movably connected to the inner side wall of the first threaded cylinder 402 by threads. One end of the screw rod 5 penetrates through the fixing plate 101 on the left side and extends to the outside of the fixing plate 101 on the left side. An installation hole 501 is penetrated and opened on the outer side wall of the first moving seat 2. A first gear 502 fixedly sleeved on the outer side wall of the first threaded cylinder 402 is arranged inside the installation hole 501. A slot hole 6 communicating with the installation hole 501 is arranged between the first moving seat 2 and the fixing plate 101 on the left side;

[0021] A second threaded cylinder 7 is installed at the right end inside the installation hole 501. A moving rod 701 is movably connected to the inner side wall of the second threaded cylinder 7 by threads. A third gear 702 meshed with the first gear 502 is fixedly sleeved on the outer side wall of the moving rod 701. A left mold 8 is installed at the right end of the moving rod 701;

[0022] Sliding plates 9 are installed on the upper and lower end faces of the second moving seat 3. Sliding blocks 901 are installed at the opposite ends of the two sliding plates 9. The outer side walls of the two sliding blocks 901 are slidably connected to sliding frames 902 installed on the upper and lower end faces of the first moving seat 2. Magnetic blocks are embedded and installed on the opposite sides of the sliding frames 902 and the limit blocks 403.

[0023] In this embodiment, when injecting the air duct of the injection-molded speaker, by starting the motor 503, the second gear 504 rotates to drive the first gear 502 to rotate, prompting the first gear 502 to drive the first threaded barrel 402 to rotate, thereby driving the first moving seat 2 to move towards the second moving seat 3. When the first moving seat 2 contacts the baffle plate 4 during the movement, the sliding frame 902 can be adsorbed on the limiting block 403 and move together with the baffle plate 4. At the same time, the right end of the second threaded barrel 7 can move to the port at the right end of the sliding hole 601, and when the first gear 502 rotates, it can drive the third gear 702 to rotate, enabling the third gear 702 to drive the moving rod 701 to rotate, prompting the moving rod 701 to rotate and move along the second threaded barrel 7. Thus, when the first moving seat 2, the baffle plate 4, and the second moving seat 3 are combined together, the moving rod 701 can push the left mold 8 into the right mold 301. Then, the injection pipe can inject the hot-melt plastic into the right mold 301 to form the air duct of the speaker. After the injection is completed, when demolding, by starting the motor 503 again, the second gear 504 drives the first gear 502 to rotate in the reverse direction, so that the first moving seat 2 moves to the left. Since the sliding frame 902 is adsorbed to the limiting block 403, when the first moving seat 2 moves to the left, it can drive the baffle plate 4 to move. When the slider 901 contacts the limiting block 403, the slider 901 can limit the limiting block 403 and prevent the baffle plate 4 from moving further. At this time, the rotation of the first gear 502 can drive the third gear 702 to rotate in the reverse direction, prompting the moving rod 701 to drive the left mold 8 to move into the slot hole 6 (original position), thereby demolding the formed air duct wrapped around the outer wall of the left mold 8, achieving the effect of directly demolding the formed product when the mold is opened, saving demolding time, and improving the processing efficiency of the speaker air duct.

[0024] As a technical optimization solution of the present utility model, a motor 503 is installed on the front end face of the first moving seat 2 through a bracket, and the output end of the motor 503 is installed with a second gear 504 that meshes with the first gear 502.

[0025] In this embodiment, by starting the motor 503, the rotation of the second gear 504 can drive the first gear 502 to rotate, so that the first gear 502 drives the first threaded barrel 402 to rotate.

[0026] As a technical optimization solution of the present utility model, a through hole 401 is provided on the outer side wall of the baffle plate 4, and the other end of the screw rod 5 passes through the through hole 401 and is slidably connected to the through hole 401. The other end of the screw rod 5 is movably connected to the second moving seat 3 through a rotating shaft.

[0027] In this embodiment, by providing the sliding connection between the screw rod 5 and the baffle plate 4, it is convenient for the baffle plate 4 to move along the screw rod 5.

[0028] As a technical optimization solution of the present utility model, a sliding hole 601 is penetratingly formed in the outer sidewall of the material retaining plate 4, and the sliding hole 601 is slidably connected with the outer sidewall of the second threaded cylinder 7.

[0029] In this embodiment: By providing the sliding hole 601, when the first moving seat 2 approaches the second moving seat 3, it is convenient for the second threaded cylinder 7 to move along the sliding hole 601.

[0030] As a technical optimization solution of the present utility model, limit blocks 403 respectively slidably connected with two sliding plates 9 are installed on the upper and lower end faces of the material retaining plate 4.

[0031] In this embodiment: By providing the limit blocks 403, when the injection-molded air duct is demolded, the slider 901 can play a role in blocking the limit blocks 403, facilitating the separation of the first moving seat 2 from the material retaining plate 4.

[0032] Working principle: First, when using this device, connect the device to an external power supply. Then connect the external hot-melt feeding pipeline to the injection molding pipeline inside the second moving seat 3. Next, when injecting the air duct of the injection molding speaker, start the motor 503, which makes the second gear 504 rotate to drive the first gear 502 to rotate. This causes the first gear 502 to drive the first threaded barrel 402 to rotate, so that the first threaded barrel 402 drives the first moving seat 2 to move towards the second moving seat 3. When the first moving seat 2 contacts the baffle 4 during the movement (since magnetic blocks are installed on the opposite sides of the sliding frame 902 and the limiting block 403, the sliding frame 902 is adsorbed on the limiting block 403), the first moving seat 2 and the baffle 4 move towards the second moving seat 3 together. At this time, the sliding frame 902 contacts the slider 901, and the slider 901 can move along the sliding frame 902. At the same time, the right end of the second threaded barrel 7 can move to the right end port of the sliding hole 601, and when the first gear 502 rotates, it can drive the third gear 702 to rotate, so that the third gear 702 can drive the moving rod 701 to rotate. This causes the moving rod 701 to rotate and move along the second threaded barrel 7. Thus, when the first moving seat 2, the baffle 4, and the second moving seat 3 are combined together, the moving rod 701 can push the left mold 8 into the right mold 301. Then the injection molding pipeline can inject the hot-melt plastic into the right mold 301 to form the air duct of the speaker by injection molding. After the injection molding is completed, when demolding, start the motor 503 again, which makes the second gear 504 drive the first gear 502 to rotate in the reverse direction, so that the first moving seat 2 moves to the left. Since the sliding frame 902 is adsorbed to the limiting block 403, when the first moving seat 2 moves to the left, it can drive the baffle 4 to move. When the slider 901 contacts the limiting block 403, the slider 901 can limit the limiting block 403 and prevent the baffle 4 from moving further. At this time, when the first gear 502 rotates, it can drive the third gear 702 to rotate in the reverse direction, causing the moving rod 701 to drive the left mold 8 to move into the slot hole 6 (original position), so as to demold the formed air duct wrapped around the outer wall of the left mold 8, realizing direct demolding of the formed product when the mold is opened.

[0033] 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 shall be included within the protection scope of the present invention.
