Description

Technical Field

[0001] This utility model relates to the field of mobile phone case processing mold technology, and in particular to mobile phone case processing mold with adjustable thickness. Background Technology

[0002] Mobile phone case processing molds are the core molding equipment in plastic injection molding. They are mainly used to produce various types and styles of mobile phone cases to meet consumers' needs for personalized and protective mobile phone appearance. With the development of intelligent and diversified home appliances, molds are widely used to manufacture components such as the outer shells and panels of home appliances, such as the outer shell molds of televisions, air conditioners, and washing machines. As consumers' personalized needs increase, the market for customized mobile phone cases is gradually expanding.

[0003] In existing technologies, traditional integral mold cavities are machined as a whole using CNC machining. It is difficult to adjust the distance between the moving and fixed molds during mobile phone case manufacturing. This makes it challenging for operators to make timely and accurate adjustments to the distance between the moving and fixed molds based on different product design requirements, material properties, and changes in production processes. When producing mobile phone cases with varying thicknesses, traditional integral mold cavities cannot easily and effectively change the distance between the moving and fixed molds. This difficulty in adjusting the mold cavity leads to problems in product thickness control, further limiting the equipment's applicability. It makes the equipment inadequate for diverse product demands and complex, ever-changing production tasks, significantly reducing its versatility and market competitiveness. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable thickness mobile phone case processing mold.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable thickness mobile phone case processing mold, including a base plate, a fixed mold body, and a moving mold body. The inner wall of the fixed mold body is provided with a convex module, the inner wall of the moving mold body is provided with a concave module, the inner wall of the moving mold body is provided with an inner moving groove, a reset groove, and a column groove. An inverted π component is slidably connected to the inner wall of the inner moving groove. A vertical column is fixed to the bottom of one end of the inverted π component. A limiting push ring is fixed to the circumference of the vertical column. A reset spring is fixed to the top of the limiting push ring. A slidably connected inclined column is slidably connected to the bottom of the reset spring. A threaded column is fixed to one end of the inclined column. An internal threaded tooth is threadedly connected to the surface of the threaded column. One end of the internal threaded tooth is rotatably connected to one side of the moving mold body. A moving tooth is meshed on the surface of the internal threaded tooth. One end of the moving tooth is rotatably connected to one side of the moving mold body. The moving tooth is driven by a drive motor.

[0006] Preferably, the convex module has positioning grooves linearly arrayed on both sides, and a chamfered piece is slidably connected to the inner wall of the fixed mold body. A connecting column is fixed to one end of the chamfered piece, and a limiting circle is fixed to one end of the connecting column. An auxiliary spring is provided on the circumference of the connecting column. In the prior art, in the composition system of mobile phone case processing molds, the convex module is often placed in the fixed mold position in the overall mold layout. When the mobile phone case processing equipment performs a stamping operation, the convex module, due to its fixed mold position, directly bears the huge impact and pressure from the stamping process. This strong external force makes this part extremely susceptible to damage, which greatly limits the design and selection of the adjustment mechanism. Some more complex adjustment mechanisms, although... Theoretically, it can achieve more precise and flexible mold adjustment functions. However, due to concerns about further damage to the punch module during stamping, or the fragility of the punch module making it difficult to effectively cooperate with, it is often difficult to apply to this type of mold structure. To address these issues, this utility model solves the problem by installing a corner cutter. When the operator needs to adjust the height position of the punch module in the fixed mold body, the limiting circle is pulled outward to retract the corner cutter into the fixed mold body. At the same time, the auxiliary spring is compressed to accumulate elastic potential energy. After adjusting the height position of the punch module in the fixed mold body, the limiting circle is released to allow the corner cutter to enter the corresponding positioning groove, thus fixing the components together and improving the service life of the equipment.

[0007] Preferably, the bottom of the concave module has a module bottom groove, both sides of the inverted π part are fixed with ladder limiting members, the top of the base plate is fixed with a track, one side of the track has a ladder sliding groove, and the inner wall of the ladder sliding groove is slidably connected to the surface of the ladder limiting member. In the prior art, during the operation of the mobile phone case processing mold, the two key components, the concave module and the inverted π part, will have obvious stability problems when facing a vibration environment. When external vibration is generated and transmitted to the mold system, the concave module and the inverted π part are prone to shaking due to their own structural characteristics and position layout in the mold. This shaking is not small and negligible, but will have a negative impact on the normal operation of the entire mold to a certain extent. With the shaking of the concave module and the inverted π part, the relative positional relationship between the components will change, causing them to be unable to accurately maintain the position specified in the initial design. The originally precisely matched parts will be affected. Positional deviations leading to excessively large or small gaps, or loose contact, not only affect the molding effect of the mold on the phone case during the forming process, making it difficult for the finished product to meet standard requirements in terms of dimensional accuracy and appearance quality, thus significantly reducing the yield rate, but more seriously, this inaccurate component positioning caused by vibration can also cause great damage to the service life of the equipment. Long-term shaking will increase the friction between various components, accelerate the wear rate, and some key connection parts will loosen due to excessive wear, or even deform or break. To address these problems, this utility model adopts the method of installing a ladder limiter to solve the problem. When the concave module and the inverted π component move, the ladder limiter of the inverted π component and the track gauge are matched, as well as the bottom groove of the module and the track gauge are matched. This ensures that the inverted π component and the concave module remain stable during the movement, preventing shaking and damage, and thus improving the yield rate.

[0008] Preferably, the inner wall of the moving mold body is provided with a parallelogram groove, and a fixing triangular piece is fixed to the surface of the inverted π piece, which realizes the effect of further improving the stability of the component by fixing the triangular piece, thereby improving the service life of the equipment.

[0009] Preferably, both sides of the convex module and both sides of the concave module are provided with oblique screw holes, and both sides of the fixed mold body and both sides of the moving mold body are provided with oblique screw holes. This achieves the matching between the oblique screw holes of the mold body and the oblique screw holes of the modules and the intervention of bolts, which greatly increases the contact area between the bolts and the components, enhances the fixing effect of the components, and improves the stability of the equipment.

[0010] Preferably, the circumferential array of the limiting circle has auxiliary ring holes, which makes it easier for workers to pry up the limiting circle with tools such as screwdrivers, thereby improving the user experience.

[0011] Preferably, the top of the inverted π component has a rectangular groove, and a top rubber pad is glued to the inner wall of the rectangular groove, which prevents collisions between components and improves the service life of the equipment.

[0012] Beneficial effects:

[0013] 1. In existing technologies, traditional integral mold cavities are machined as a single unit using CNC machining. However, it is difficult to adjust the distance between the moving and fixed molds during mobile phone case manufacturing. This makes it challenging for operators to adjust the distance accurately and in a timely manner according to the design requirements, material properties, and production process variations of different products. When producing mobile phone cases with varying thicknesses, traditional integral mold cavities cannot easily and effectively change the distance between the moving and fixed molds. This difficulty in adjusting the mold cavity leads to problems in product thickness control, further limiting the applicability of the equipment. It makes the equipment inadequate for diverse product demands and complex production tasks, significantly reducing its versatility and market competitiveness. To address this issue, this invention uses an inverted π-shaped component to solve the problem, allowing operators to adjust the distance as needed. When the module is positioned at a certain height within the moving mold body, the drive motor is activated, causing the actuating gear to rotate and engage, thus rotating the internal threaded gear. The threaded connection pushes the threaded column inward or pulls the inclined column outward. When pushed inward, the inclined surface at one end of the inclined column pushes the vertical column upward and compresses the return spring, causing the inverted π piece to lift the concave module upward. When the inclined column is pulled outward, a gap is created below the vertical column, and the return spring releases its elastic potential energy, causing the vertical column to descend. This allows the position height of the concave module within the moving mold body to be easily changed. At the same time, the sliding connection between the limiting block and the inner wall of the moving mold body restricts the movement of the vertical column and the inclined column, ensuring that the movement of the vertical column and the inclined column maintains a predetermined trajectory. Meanwhile, the inverted π piece, through its superior force transmission and load-bearing structure, supports the concave module, allowing the mold to maintain stability during stamping. Thus, by changing the position height of the concave module within the moving mold body, the thickness of the phone case can be adjusted, thereby improving the applicability of the equipment.

[0014] 2. In the existing technology, in the composition system of mobile phone case processing molds, the protruding module is often placed in the fixed mold position in the overall layout of the mold. When the mobile phone case processing equipment performs stamping operation, the protruding module, due to its fixed mold position, directly bears the huge impact and pressure from the stamping process. This strong external force makes this part extremely susceptible to damage, which greatly limits the design and selection of the adjustment mechanism. Although some more complex adjustment mechanisms can theoretically achieve more precise and flexible mold adjustment functions, they are often unsuitable for this type of mold structure due to concerns about further damage to the protruding module during the stamping process or the difficulty in effectively cooperating with it due to the fragility of the protruding module. To address this problem, this utility model solves the problem by installing a corner cutter. When the operator needs to adjust the height position of the protruding module in the fixed mold body, the limiting circle is pulled outward to retract the corner cutter into the fixed mold body, while the auxiliary spring is compressed to accumulate elastic potential energy. After adjusting the height position of the protruding module in the fixed mold body, the limiting circle is released to allow the corner cutter to enter the corresponding positioning groove, thus fixing the components together and improving the service life of the equipment.

[0015] 3. In existing technologies, during the operation of mobile phone case processing molds, the two key components, the recessed module and the inverted π part, exhibit significant stability issues when exposed to vibration. When external vibrations are generated and transmitted to the mold system, the recessed module and the inverted π part, due to their structural characteristics and positional layout within the mold, are prone to wobbling. This wobbling is not minor or negligible; rather, it negatively impacts the normal operation of the entire mold to a certain extent. As the recessed module and the inverted π part wobble, the relative positional relationship between the components changes, causing them to fail to accurately maintain the positions specified in the initial design. Originally precisely fitted components experience gaps that are too large or too small, or loose contact, due to positional shifts. This not only affects the mold's molding process... The shaping process of the phone case during production makes it difficult for the finished product to meet the standard requirements in terms of dimensional accuracy and appearance quality, resulting in a significant decrease in yield. More seriously, the inaccurate component positioning caused by vibration can also cause great damage to the service life of the equipment. Long-term shaking will increase the friction between various components, accelerate the wear rate, and some key connection parts will loosen due to excessive wear, or even deform or break. To address these issues, this utility model adopts the method of installing a ladder limiter to solve the problem. When the concave module and the inverted π component move, the ladder limiter of the inverted π component and the track gauge are matched, as well as the bottom groove of the module and the track gauge are matched. This ensures that the inverted π component and the concave module remain stable during the movement, preventing shaking and damage, and thus improving the yield. Attached Figure Description

Detailed Implementation

[0026] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0027] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0029] Reference Figure 1-8An adjustable-thickness mobile phone case processing mold includes a base plate 102, a fixed mold body 1, and a moving mold body 103. The fixed mold body 1 has a protruding module 101 on its inner wall, and the moving mold body 103 has a concave module 104 on its inner wall. The moving mold body 103 has an inner moving groove 2 and a reset groove 202 on its inner wall. A column groove 203 is also provided on the inner wall of the moving mold body 103. An inverted π-piece 201 is slidably connected to the inner wall of the inner moving groove 2. A vertical column 204 is fixed to the bottom of one end of the inverted π-piece 201, and the circumference of the vertical column 204 is fixed with a limited... Push ring 205, with a return spring 206 fixed at the top of push ring 205, and a slidable inclined column 207 at the bottom of return spring 206. A threaded column 208 is fixed at one end of inclined column 207, and an internal threaded tooth 209 is threadedly connected to the surface of threaded column 208. One end of internal threaded tooth 209 is rotatably connected to one side of moving mold body 103, and a moving tooth 2010 is engaged on the surface of internal threaded tooth 209. One end of moving tooth 2010 is rotatably connected to one side of moving mold body 103, and moving tooth 2010 is driven by drive motor 2011. The protruding module 101 has positioning grooves 3 linearly arrayed on both sides. A corner cutter 301 is slidably connected to the inner wall of the fixed mold body 1. A connecting column 302 is fixed to one end of the corner cutter 301, and a limiting circle 303 is fixed to one end of the connecting column 302. An auxiliary spring 304 is provided on the circumference of the connecting column 302. In the composition system of the mobile phone case processing mold, the protruding module 101 is often placed in the fixed mold position in the overall mold layout. When the mobile phone case processing equipment performs a stamping operation, the protruding module 101, due to its fixed mold position, directly bears the huge impact and pressure from the stamping process. This strong external force makes this part very susceptible to damage, which greatly limits the design and selection of the adjustment mechanism. Some more complex adjustment mechanisms, although theoretically able to To achieve more precise and flexible mold adjustment, but due to concerns about further damage to the punch module 101 during stamping, or the fragility of the punch module 101 making it difficult to effectively cooperate with, it is often unsuitable for this type of mold structure. The solution is to install a corner cutter 301. When the operator needs to adjust the height position of the punch module 101 in the fixed mold body 1, the limiting circle 303 is pulled outward to retract the corner cutter 301 into the fixed mold body 1. At the same time, the auxiliary spring 304 is compressed to accumulate elastic potential energy. After adjusting the height position of the punch module 101 in the fixed mold body 1, the limiting circle 303 is released to allow the corner cutter 301 to enter the corresponding positioning groove 3, thus fixing the components together and improving the service life of the equipment.

[0030] The bottom of the recessed module 104 has a module bottom groove 4. Step limiters 401 are fixed to both sides of the inverted π-part 201. A guide rail 402 is fixed to the top of the base plate 102. A step slide groove 403 is formed on one side of the guide rail 402. The inner wall of the step slide groove 403 is slidably connected to the surface of the step limiter 401. During the operation of the mobile phone case processing mold, the two key components, the recessed module 104 and the inverted π-part 201, exhibit significant stability problems when exposed to vibration. When external vibrations are generated and transmitted to the mold system, the recessed module 104 and the inverted π-part 201 are prone to shaking due to their structural characteristics and positional layout within the mold. This shaking is not minor or negligible; rather, it negatively impacts the normal operation of the entire mold to a certain extent. As the recessed module 104 and the inverted π-part 201 shake, the relative positional relationship between the components changes, causing them to fail to accurately maintain the positions specified in the initial design. The originally precisely matched components... The misalignment of individual components can lead to gaps that are too large or too small, or poor contact. This not only affects the molding effect of the mold on the phone case during the forming process, making it difficult for the finished product to meet the standard requirements in terms of dimensional accuracy and appearance quality, thus resulting in a significant decrease in yield, but more seriously, this inaccurate component positioning caused by vibration can also cause great damage to the service life of the equipment. Long-term shaking will increase the friction between the various components, accelerate the wear rate, and some key connection parts will loosen due to excessive wear, or even deform or break. The problem is solved by installing a ladder limiter 401. This achieves the matching of the ladder limiter 401 of the inverted π part 201 with the track 402, and the matching between the module bottom groove 4 and the track 402 when the concave module 104 and the inverted π part 201 move. This ensures that the inverted π part 201 and the concave module 104 remain stable during the movement, preventing shaking and damage, and thus improving the yield. The inner wall of the moving mold body 103 has a parallelogram groove 5, and a fixing triangular piece 501 is fixed to the surface of the inverted π-part 201. This fixing triangular piece 501 further improves the stability of the component, thus extending the service life of the equipment. Both sides of the convex module 101 and both sides of the concave module 104 have oblique screw holes 6, and both sides of the fixed mold body 1 and both sides of the moving mold body 103 have oblique screw holes 601. The fit between the oblique screw holes 601 and the oblique screw holes 601, along with the bolt insertion, greatly increases the contact area between the bolt and the component, enhancing the component's fixing effect and improving equipment stability. The circumferential array of the limiting circle 303 has auxiliary ring holes 7, allowing workers to easily pry it up with screwdrivers or other tools, improving user experience. The top of the inverted π-part 201 has a rectangular groove, and a top rubber pad 8 is glued to the inner wall of the groove to prevent collisions between components, further extending the service life of the equipment.

[0031] The working principle of this utility model is as follows: When the operator needs to adjust the position and height of the concave module 104 in the moving mold body 103, the drive motor 2011 is started to make the actuating gear 2010 rotate and engage, causing the internal threaded gear 209 to rotate. The threaded connection causes the threaded column 208 to push inward or pull outward the inclined column 207. When pushing inward, the inclined surface at one end of the inclined column 207 pushes the vertical column 204 upward and compresses the return spring 206, causing the inverted part 201 to lift the concave module 104 upward. When pulling outward, the inclined column 207 creates a gap below the vertical column 204, and the return spring... 206 releases elastic potential energy, causing the vertical column 204 to descend, allowing the position height of the concave module 104 in the moving mold body 103 to be easily changed. At the same time, the sliding connection between the limiting block and the inner wall of the moving mold body 103 restricts the movement of the vertical column 204 and the inclined column 207 to maintain a predetermined trajectory. Meanwhile, the inverted π piece 201 supports the concave module 104 through its own better force transmission and load-bearing structure, so that the mold can maintain better stability during stamping. Thus, the thickness of the mobile phone case can be adjusted by changing the position height of the concave module 104 in the moving mold body 103.
