Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for forming a walkie-talkie knob. Background Technology

[0002] Walkie-talkie knob molding mold is a special tooling mold used for mass production of walkie-talkie knob parts. Its core function is to use injection molding process to heat and melt plastic raw materials and inject them into the mold cavity. After cooling and solidification, it forms a finished knob with a specific shape, size and function to meet the assembly and use requirements of walkie-talkies.

[0003] A search revealed Chinese patent publication number CN215661704U, which discloses a mold for molding a plastic shell for a walkie-talkie. The mold includes a moving mold assembly, a fixed mold assembly, and a heating device. The moving mold assembly consists of a top plate, a moving mold base plate, and a cavity. The top plate has an injection nozzle at its top and several guide pillars at its bottom. The moving mold base plate has guide sleeves that mate with the guide pillars. The cavity is located at the bottom end of the moving mold base plate. The fixed mold assembly consists of a base plate, an ejector plate, an ejector pin fixing plate, and a core. One end of the base plate has a pad placed between the base plate and the ejector plate. The ejector plate has a return spring at its end near the base plate and several ejector pins at its other end. The ejector pin fixing plate has ejector pin holes that mate with the ejector pins. Through the ejector pins and ejector pin holes, the ejector pin fixing plate is attached to one end of the ejector plate. The core is located at the end of the ejector pin fixing plate away from the ejector plate, and a core fixing plate surrounds the core.

[0004] In existing technology, after the knob is formed, it shrinks due to cooling and fits tightly against the mold core. However, manual demolding prolongs the demolding time and cannot guarantee the uniformity of the demolding force, thus reducing the precision of the formed knob and production efficiency. Utility Model Content To overcome the above shortcomings, this utility model provides a walkie-talkie knob molding mold, which aims to solve the problem in the prior art that after molding, the knob will shrink due to cooling and fit tightly with the mold core, which will prolong the demolding time when manually demolding and make it impossible to ensure the uniformity of demolding force, thus reducing production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a walkie-talkie knob molding mold, comprising a slide plate, a rotating rod rotatably connected to the inner wall of the slide plate, a rotating rod rotatably connected to the inner wall of the rotating rod rotatably, a fixing post fixedly connected to the upper surface of the slide plate, a guide post rotatably connected to the top of the fixing post, a fixing block slidably connected to the outer wall of the guide post, a housing rotatably connected to the outer wall of the fixing block, a push rod slidably connected to the inner wall of the housing rotatably, the bottom end of the push rod fixedly connected to the inner wall of the guide post, a tension spring fixedly connected to the inner wall of the housing rotatably, the top end of the tension spring fixedly connected to the outer wall of the push rod, an ejector block fixedly connected to the top end of the push rod, the outer wall of the ejector block slidably connected to the inner wall of the housing rotatably, and a casting component provided on the outer wall of the rotating rod rotatably.

[0006] Through the above technical solution: when the slider pulls the slide plate, the slide plate pulls the rotating rod one to rotate, which in turn drives the rotating rod two to rotate synchronously on the inner wall of the lower fixed plate, enabling the slide plate to achieve a stable sliding effect. When the slide plate rises, it pushes the fixed column to slide synchronously, causing the fixed column to push the guide column to slide on the outer wall of the fixed block. The fixed block is fixed on the inner wall of the outer shell, allowing the fixed block to drive the guide column to rotate on the outer wall of the fixed column, thereby causing the guide column to push the push rod to slide, enabling the push rod to achieve a stable extension and retraction effect. The push rod pushes the ejector block to slide on the inner wall of the outer shell, and the ejector block will pull the tension spring fixed on the inner wall of the outer shell, enabling the ejector block to achieve a stable ejection effect. When the slide plate descends, the fixed column will pull the guide column and drive the push rod to slide synchronously. At the same time, the tension spring will pull the ejector block, enabling the ejector block to achieve a quick reset effect. After the ejector block resets, it will remain horizontal with the upper surface of the outer shell, which can prevent the pouring material from entering the interior of the outer shell.

[0007] As a further description of the above technical solution: The casting assembly includes a lower fixed plate, the inner wall of which is rotatably connected to the outer wall of the rotating rod two, and the inner wall of which is slidably connected to the outer wall of the slide plate. A male template is fixedly connected to the upper surface of the lower fixed plate, the inner wall of which is slidably connected to the outer wall of the fixed column, and the inner wall of which is fixedly connected to the outer wall of the outer shell one. A female template is provided on the upper surface of the male template, a flow channel plate is fixedly connected to the upper surface of the female template, and an upper fixed plate is fixedly connected to the upper surface of the flow channel plate. A casting channel is provided on the inner wall of the upper fixed plate, a slider is provided on the outer wall of the female template, the inner wall of which is slidably connected to the outer wall of the male template, and a cleaning component is provided on the inner wall of the casting channel.

[0008] The above technical solution achieves the following: by fixing the outer shell to the inner wall of the male template, and the male template to the upper surface of the lower fixing plate, the outer shell can be prevented from falling off. The mold core installed inside the male and female templates allows the ejector block to stably eject the product from the mold core. The female template and male template are connected by a slider, allowing the female template to drive the slider to slide stably on the outer wall of the male template, thus preventing the mold core from shifting. The flow channel plate fixed to the upper surface of the female template connects to the pouring channel, and the pouring channel and flow channel plate are connected by an upper fixing plate, allowing the pouring material to be poured out stably.

[0009] As a further description of the above technical solution: The cleaning component includes a guide plate, the outer wall of which is fixedly connected to the inner wall of the pouring channel, and an mounting plate is snapped onto the outer wall of the guide plate.

[0010] The above technical solution involves installing the mounting plate onto the outer wall of the guide plate, which is then fixed to the inner wall of the pouring channel. This allows the mounting plate to quickly open and close the pouring port, preventing foreign objects from entering the pouring port when the equipment is not in use. Furthermore, when rotating to clean the pouring port, the mounting plate will be locked against the outer wall of the guide plate, preventing it from falling off.

[0011] As a further description of the above technical solution: A hollow column is fixedly connected to the upper surface of the mounting plate, and the outer wall of the hollow column is detachably installed on the upper surface of the pouring channel.

[0012] The above technical solution involves the hollow column driving the mounting plate to hold the guide plate in place. At the same time, the outer walls of both sides of the hollow column are installed on the outer wall of the pouring channel, which can prevent the hollow column from falling off. Furthermore, the rotation of the hollow column on the outer wall of the pouring channel can achieve a guiding function.

[0013] As a further description of the above technical solution: A pressing rod is slidably connected to the inner wall of the hollow column, and a telescopic column is slidably connected to the outer wall of the pressing rod. The outer wall of the telescopic column is slidably connected to the inner wall of the hollow column.

[0014] The above technical solution allows the telescopic column to slide along the inner wall of the hollow column by pressing the sliding rod, thus enabling the hollow column to extend stably. The hollow column can also limit the movement of the telescopic column.

[0015] As a further description of the above technical solution: The outer wall of the telescopic column is fixedly connected to a limit block, the bottom end of the pressing rod is fixedly connected to an upper cross block, and the outer wall of the lower cross block is fixedly connected to the inner wall of the telescopic column.

[0016] The above technical solution works as follows: pushing the telescopic column with the pressing rod will cause the limiting block to slide synchronously, which can prevent the telescopic column from falling off. After the telescopic column drives the limiting block to slide to the appropriate position, pushing the pressing rod will cause the upper cross block to slide on the inner wall of the telescopic column, while the lower cross block is fixed on the inner wall of the telescopic column, which can make the pressing rod slide stably.

[0017] As a further description of the above technical solution: The inner wall of the cross block is rotatably connected to a connecting rod, the outer wall of the connecting rod is rotatably connected to a scraper, the outer wall of the scraper is slidably connected to the inner wall of the telescopic column, and the outer wall of the hollow column is provided with a self-locking component.

[0018] The above technical solution allows the connecting rod to rotate in a crisscross motion by pushing the upper and lower cross blocks, thus achieving a stable pushing and pulling effect on the scraper. The scraper slides on the inner wall of the telescopic column, causing it to press against the pouring pipe, and the rotation of the scraper achieves a stable cleaning effect.

[0019] As a further description of the above technical solution: The self-locking assembly includes a hollow block, the outer wall of which is fixedly connected to the inner wall of a hollow column. A spring is provided on the inner wall of the hollow block, and a locking block is fixedly connected to the left end of the spring. The outer wall of the locking block is slidably connected to the inner wall of the hollow block and is engaged with the inner wall of the limiting block.

[0020] The above technical solution works as follows: a hollow block fixed to the inner wall of a hollow column drives a spring to push a locking block out, and the locking block slides on the inner wall of the hollow block, which can prevent the locking block from falling off. The upper locking block locks the limiting block, and the lower locking block abuts against the scraper, which can prevent the limiting block from falling off. When the lower locking block locks the limiting block, it can prevent the limiting block from shifting.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the sliding block pushes and pulls the sliding plate, which drives the rotating rod one to rotate on the inner wall of the rotating rod two. The sliding plate pushes and pulls the fixed column, which drives the guide column and the push rod to slide synchronously. At the same time, the push rod pulls the ejector block to slide, which drives the guide column to rotate on the outer wall of the fixed block. The ejector block can stably eject the forming knob, thereby improving the precision of the forming knob and the production efficiency.

[0022] 2. In this utility model, the hollow column and the mounting plate are installed on the outer wall of the guide plate. When the pressing rod is pushed, the telescopic column and the cross block slide synchronously. The cross block will push the connecting rod to rotate, thereby causing the scraper to extend. The scraper can scrape off the residual material, so as to keep the pouring channel unobstructed and prevent molding defects or production interruptions caused by blockage.

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.

[0026] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a walkie-talkie knob molding mold, including a slide plate 1, a rotating rod 11 rotatably connected to the inner wall of the slide plate 1, a rotating rod 12 rotatably connected to the inner wall of the rotating rod 11, a fixing post 13 fixedly connected to the upper surface of the slide plate 1, a guide post 14 rotatably connected to the top of the fixing post 13, a fixing block 15 slidably connected to the outer wall of the guide post 14, a housing 17 fixedly connected to the outer wall of the fixing block 15, a push rod 16 slidably connected to the inner wall of the housing 17, the bottom end of the push rod 16 fixedly connected to the inner wall of the guide post 14, a tension spring 18 fixedly connected to the inner wall of the housing 17, the top end of the tension spring 18 fixedly connected to the outer wall of the push rod 16, an ejector block 19 fixedly connected to the top of the push rod 16, the outer wall of the ejector block 19 slidably connected to the inner wall of the housing 17, and a rotating rod 12... The outer wall is provided with a casting component 2, which includes a lower fixed plate 21. The inner wall of the lower fixed plate 21 is rotatably connected to the outer wall of the rotating rod 12, and the inner wall of the lower fixed plate 21 is slidably connected to the outer wall of the slide plate 1. The upper surface of the lower fixed plate 21 is fixedly connected to a male template 22, the inner wall of the male template 22 is slidably connected to the outer wall of the fixed column 13, and the inner wall of the male template 22 is fixedly connected to the outer wall of the outer shell 17. The upper surface of the male template 22 is provided with a female template 23, the upper surface of the female template 23 is fixedly connected with a flow channel plate 24, the upper surface of the flow channel plate 24 is fixedly connected with an upper fixed plate 25, the inner wall of the upper fixed plate 25 is provided with a casting channel 26, the outer wall of the female template 23 is provided with a slider 27, the inner wall of the slider 27 is slidably connected to the outer wall of the male template 22, and the inner wall of the casting channel 26 is provided with a cleaning component 3. Specifically, by installing the pouring channel 26 onto the inner wall of the upper fixed plate 25 and connecting the pouring channel 26 to the flow channel plate 24, which is fixed to the lower surface of the upper fixed plate 25, the pouring channel 26 can achieve a stable conveying effect of pouring material. By installing the female template 23 onto the lower surface of the flow channel plate 24, the female template 23 slides on the upper surface of the male template 22. The female template 23 is connected to the male template 22 via the slider 27, which allows the female template 23 and the male template 22 to achieve a stable closure and prevent displacement. By fixing the male template 22 to the upper surface of the lower fixed plate 21, the female template 23 pushes and pulls the slider 27, which simultaneously drives the slide plate 1 to slide synchronously. The slide plate 1 pulls the rotating rod 11 to rotate, which simultaneously drives the rotating rod 12 to rotate synchronously. The rotating rod 12 rotates within the lower fixed plate 21. The wall allows the rotating rod 11 to slide stably and prevent it from falling off. The sliding plate 1 pushes the fixed column 13 to slide on the inner wall of the male template 22. The fixed column 13 pushes the guide column 14 to slide, which in turn drives the push rod 16 to slide on the inner wall of the outer shell 17. The guide column 14 slides on the outer wall of the fixed block 15, and the fixed block 15 is fixed on the inner wall of the outer shell 17. This allows the push rod 16 to achieve a stable extension and retraction effect. The outer shell 17 is fixed on the inner wall of the male template 22, which allows the push rod 16 to push the ejector block 19 to slide on the inner wall of the outer shell 17. The sliding of the push rod 16 will pull the tension spring 18 fixed on the inner wall of the outer shell 17, which can provide power for the reset of the ejector block 19. The ejector block 19 can stably eject the forming knob, thereby improving the precision of the forming knob and the production efficiency.

[0027] Reference Figure 1 , Figure 2 and Figure 4 The cleaning component 3 includes a guide plate 31, the outer wall of which is fixedly connected to the inner wall of the pouring channel 26. An installation plate 32 is snapped onto the outer wall of the guide plate 31. A hollow column 33 is fixedly connected to the upper surface of the installation plate 32. The outer wall of the hollow column 33 is detachably installed on the upper surface of the pouring channel 26. A pressing rod 34 is slidably connected to the inner wall of the hollow column 33. A telescopic column 35 is slidably connected to the outer wall of the pressing rod 34. The outer wall of the telescopic column 35 is slidably connected to the inner wall of the hollow column 33. A limit block 36 is fixedly connected to the outer wall of the telescopic column 35. An upper cross block 37 is fixedly connected to the bottom end of the pressing rod 34. The outer wall of the lower cross block 37 is fixedly connected to the inner wall of the telescopic column 35. A connecting rod 38 is rotatably connected to the inner wall of the cross block 37. A scraper 39 is rotatably connected to the outer wall of the connecting rod 38. The outer wall of the scraper 39 is slidably connected to the inner wall of the telescopic column 35. A self-locking component 4 is provided on the outer wall of the hollow column 33. Specifically, by installing the hollow column 33 onto the upper surface of the pouring channel 26, the hollow column 33 causes the mounting plate 32 to slide against the outer wall of the guide plate 31, while the guide plate 31 is fixed to the inner wall of the pouring channel 26. This allows the hollow column 33 to rotate, enabling the mounting plate 32 to rotate stably against the outer wall of the guide plate 31. Pushing the pressing rod 34 causes the telescopic column 35 and the limiting block 36 to slide synchronously against the inner wall of the hollow column 33. When the telescopic column 35 extends, the pressing rod 34 pushes the upper cross block 37 to slide. On the inner wall of the telescopic column 35, the lower cross block 37 is fixed to the inner wall of the telescopic column 35, which enables the cross block 37 to stably push the connecting rod 38 to rotate crosswise. The connecting rod 38 pushes the scraper 39 to slide out of the telescopic column 35 and makes the scraper 39 press against the inner wall of the pouring channel 26, which enables the scraper 39 to stably clean the pipeline. The scraper 39 can scrape off residual materials, thereby keeping the pouring channel 26 unobstructed and preventing molding defects or production interruptions caused by blockage.

[0028] Reference Figure 1 , Figure 2 and Figure 5 The self-locking component 4 includes a hollow block 41, the outer wall of which is fixedly connected to the inner wall of the hollow column 33. A spring 42 is provided on the inner wall of the hollow block 41. A locking block 43 is fixedly connected to the left end of the spring 42. The outer wall of the locking block 43 is slidably connected to the inner wall of the hollow block 41. The outer wall of the locking block 43 is engaged with the inner wall of the limiting block 36. Specifically, the telescopic column 35 drives the limiting block 36 to slide on the outer wall of the locking block 43, so that the locking block 43 slides on the inner wall of the hollow block 41 and compresses the spring 42, which enables the locking block 43 to stably lock the limiting block 36. When the upper four sets of hollow blocks 41 lock the limiting block 36, the lower four sets of hollow blocks 41 will abut against the scraper 39, which can prevent the scraper 39 from falling off.

[0029] Working principle: When the mold is needed, the pouring channel 26 is installed in the upper fixed plate 25, so that the pouring pipe of the pouring channel 26 is connected to the runner plate 24. The runner plate 24 heats the pouring material and delivers it to the mold core installed on the inner wall of the female mold plate 23, so that the female mold plate 23 can inject the mold core installed on the inner wall of the male mold plate 22. The female mold plate 23 and the male mold plate 22 are connected by the slider 27, which can improve the precision of the product. When the female template 23 is raised, the slider 27 pulls the slide plate 1 to slide on the inner wall of the rotating rod 12. The rotating rod 11, which rotates the inner wall of the slide plate 1, pulls the rotating rod 12 to rotate on the inner wall of the lower fixed plate 21, thus preventing the slide plate 1 from falling off. The rotating rod 11 pushes the fixed column 13 to slide on the inner wall of the male template 22, and the rotating rod 12 pushes the guide column 14 to slide on the outer wall of the fixed block 15. The fixed block 15 is fixed to the inner wall of the outer shell 17, and the outer shell 17 is fixed to the male template. The inner wall of 22 allows the guide post 14 to rotate stably. The guide post 14 pushes the push rod 16 to slide on the inner wall of the outer shell 17, so that the push rod 16 pushes the ejector block 19 to slide on the inner wall of the outer shell 17. The push rod 16 will pull the tension spring 18, which can make the ejector block 19 stably eject the product. The tension spring 18 and the push rod 16 pull the ejector block 19 to reset and keep it horizontal with the upper surface of the outer shell 17, which can prevent material from entering the interior of the outer shell 17. By installing the pressing rod 34 on the upper surface of the pouring channel 26, the pressing rod 34 causes the mounting plate 32 to slide against the outer wall of the guide plate 31, while the guide plate 31 is fixed to the inner wall of the pouring channel 26. This allows the hollow column 33 to quickly open or close the pouring port. By pushing the pressing rod 34 to slide against the inner walls of the hollow column 33 and the telescopic column 35, the pressing rod 34 pushes the telescopic column 35 to slide against the inner wall of the hollow column 33. The telescopic column 35 then pushes the limiting block 36 away from the outer wall of the upper locking block 43 and slides against the outer wall of the lower locking block 43, thereby allowing the inner wall of the hollow block 41 to... Spring 42 pushes the lower side locking block 43 to lock the limiting block 36, which can quickly fix the position of the telescopic column 35. Pushing the pressing rod 34 again will push the cross block 37 to slide, so that the cross block 37 pushes the connecting rod 38 to rotate and pushes the scraper 39 to press against the pouring port. This can rotate the hollow column 33 to quickly clean the pouring port. This mold can not only stably eject the forming knob, thereby improving the precision of the forming knob and production efficiency, but also scrape off residual materials, thereby keeping the pouring channel 26 unobstructed and preventing molding defects or production interruptions caused by blockage.
