Description

Technical Field

[0001] This utility model relates to the technical field of injection molding parts processing equipment, and in particular to an injection molding parts flattening and shaping mechanism. Background Technology

[0002] Injection-molded parts are components manufactured using the injection molding process. Injection molding is a common plastic processing method where molten plastic raw material is injected into a mold cavity, and after cooling and solidification, a plastic product with a specific shape and size is formed. These plastic products are injection-molded parts, and their applications are extremely wide, appearing in many fields such as automobile manufacturing, electronic equipment, and daily necessities. For example, plastic parts for automotive interiors, mobile phone casings, and plastic tableware are typical injection-molded parts. With their good plasticity, low cost, and diverse molding effects, they have become an indispensable part of modern industrial production.

[0003] Flattening and shaping of injection-molded parts is a crucial processing step after injection molding. During the injection molding process, parts may deform or have uneven surfaces, affecting their dimensional accuracy and appearance. Therefore, flattening and shaping are necessary. This process mainly involves applying pressure to the injection-molded parts using specific equipment and techniques to restore them to the shape and dimensions required by the design. For example, some injection-molded parts may have minor protrusions or depressions on their surface after demolding, or their overall shape may be slightly distorted. Flattening and shaping can use mechanical pressure or other technical means to correct these defects, making the part surface smooth and the dimensions more accurate. This improves the quality of the injection-molded parts, enabling them to meet the needs of actual use and better adapt to subsequent assembly processes or be put into direct use.

[0004] In the existing technology, the clamping and positioning methods for the flattening and shaping of some injection molded parts are relatively simple. Traditional clamping methods are mostly only applicable to injection molded parts with regular shapes and simple structures. When faced with injection molded parts with different shapes and complex structures, it is difficult to clamp them stably and flatten them. Therefore, a flattening and shaping mechanism for injection molded parts is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a flattening and shaping mechanism for injection molded parts, which aims to improve the problem that the existing technology has a single clamping and positioning method when flattening and shaping some injection molded parts, making it difficult to stably clamp and flatten injection molded parts with different shapes and complex structures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flattening and shaping mechanism for injection molded parts includes a base and an injection molded part. A support frame is fixedly connected to the top of the base, and a flattening machine is slidably connected to the top of the support frame. A flipping mechanism is provided at the top of the base, and a clamping mechanism is fixedly connected to the left end of the flipping mechanism.

[0008] The clamping mechanism includes a fixing block. The right end of the fixing block is fixedly connected to the left end of the flipping mechanism. A motor is fixedly connected inside the fixing block. A rotating shaft is fixedly connected to the drive end of the motor. A gear is fixedly connected to the outside of the rotating shaft. A rack plate is slidably connected to the inner wall of the fixing block. The outside of the rack plate is meshed with the outside of the gear. An L-shaped plate is fixedly connected to the left side of the rack plate. One of the square plates is fixedly connected to the front end of the L-shaped plate. Another square plate is fixedly connected to the front end of the fixing block. An adaptation component is provided inside the square plate.

[0009] Through the above technical solution, the base, support frame, flattening machine, flipping mechanism and clamping mechanism work together to realize the complete processing flow of injection molded parts from clamping, flipping to flattening. This integrated design provides a systematic solution for the flattening and shaping of injection molded parts, and improves the continuity and efficiency of processing.

[0010] As a further description of the above technical solution:

[0011] Guide plates are fixedly connected to both the upper and lower sides of the rack plate, and guide grooves are provided on the inner walls of both the upper and lower sides of the fixing block. The outer wall of the guide plate is slidably connected to the inner wall of the guide groove.

[0012] The above technical solution, namely the design of the guide plate and guide groove, effectively restricts the movement trajectory of the rack plate. When the gear drives the rack plate to slide, the guide plate slides in the guide groove, ensuring that the rack plate can only move smoothly in the predetermined direction, avoiding deviation or shaking, thereby ensuring the stability and accuracy of the clamping action and improving the reliability of clamping injection molded parts.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the rotating shaft is rotatably connected to the inner wall of the fixed block, and the outer wall of the L-shaped plate is slidably connected to the inner wall of the fixed block.

[0015] The above technical solution ensures that the gear can rotate stably around the shaft through the rotational connection between the shaft and the fixed block, providing stable power output for the meshing transmission between the gear and the rack plate. At the same time, the sliding connection between the L-shaped plate and the fixed block allows the L-shaped plate to smoothly transmit the movement of the rack plate, accurately drive the square plate to move, and achieve effective clamping of the injection molded parts.

[0016] As a further description of the above technical solution:

[0017] The adaptation component includes bolts, the square plate has multiple through holes inside, the outer wall of the bolt is rotatably connected to the inner wall of the through holes, the bolt is threaded with a nut, a positioning rod is fixedly connected to the left side of the right bolt, and a clamping rod is fixedly connected to the right side of the left bolt.

[0018] The above technical solution greatly enhances the versatility of the clamping mechanism through the design of the adaptive components. By selecting appropriate positions to install bolts in the multiple through holes of the square plate and fixing them with nuts, the positions of the positioning rod and clamping rod can be flexibly adjusted to meet the positioning and clamping requirements of injection molded parts of different shapes, thereby improving the equipment's adaptability to the processing of complex parts.

[0019] As a further description of the above technical solution:

[0020] The injection-molded part has a positioning hole inside, the outer wall of the positioning rod contacts the inner wall of the positioning hole, and the right side of the clamping rod contacts the left side of the injection-molded part.

[0021] Through the above technical solution, the positioning rod and the positioning hole of the injection molded part are matched to achieve precise positioning of the part, ensuring the positional accuracy of the part during clamping and processing. The clamping rod is in close contact with the side of the part, further stabilizing the clamping of the part and preventing displacement of the part during processing, thus ensuring processing accuracy.

[0022] As a further description of the above technical solution:

[0023] The inner wall of the through hole is provided with a fixing groove, and the outer wall of the nut is engaged with the inner wall of the fixing groove;

[0024] The above technical solution, with its locking structure between the fixing groove and the nut, effectively prevents the nut from loosening after tightening, ensuring the fixed positions of the bolt, positioning rod, and clamping rod, maintaining stable clamping of the injection molded parts, and improving the reliability and stability of the entire clamping process.

[0025] As a further description of the above technical solution:

[0026] The flipping mechanism includes a protective box, the bottom of which is fixedly connected to the top of the base. A drive motor is installed inside the protective box, and a rotating rod is fixedly connected to the drive end of the drive motor. A connecting plate is fixedly connected to the left end of the rotating rod, and the right end of the fixing block is fixedly connected to the left end of the connecting plate.

[0027] Through the above technical solution, the protective box of the flipping mechanism not only protects the internal drive motor and other components from the influence of the external environment and extends the service life of the components, but also plays a safety protection role. The cooperation of the drive motor, rotating rod and connecting plate provides power for the flipping of the clamping mechanism and injection molded parts, realizes the processing of different surfaces of the parts, and improves the comprehensiveness of the processing.

[0028] As a further description of the above technical solution:

[0029] A pad is fixedly connected to the top of the base, and two support seats are fixedly connected to the top of the pad. The outer wall of the rotating rod is rotatably connected to the inner wall of the two support seats.

[0030] The above technical solution, with its pad and support base, provides stable support and precise positioning for the rotating rod. During the flipping process, the rotating rod rotates smoothly within the support base, ensuring the stability and accuracy of the flipping action. This enables precise machining of different surfaces of the injection molded parts and improves the machining quality.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the motor drives the gear to rotate, which in turn causes the rack plate to slide, thereby enabling the L-shaped plate to move the square plate to achieve initial clamping. Multiple through holes, bolts, nuts, positioning rods, and clamping rods of the component work together. According to the shape of the part, a suitable through hole mounting bolt is selected, and the positioning rod is aligned with the positioning hole of the injection molded part for precise positioning. Then, it is fixed by the nut, so that the clamping rod is in close contact with the part and firmly clamped. This design can adapt to injection molded parts of different shapes, improve the accuracy and efficiency of clamping and positioning, ensure that the part will not be displaced during processing, and provide a reliable foundation for subsequent flattening and shaping.

[0033] 2. In this utility model, the drive motor inside the protective box provides power for rotation, driving the rotating rod to rotate. The rotating rod drives the clamping mechanism and the injection molded parts it clamps to flip through the connecting plate. During the flipping process, the outer wall of the rotating rod rotates on the inner wall of the two support seats on the top plate of the base. The support seats support and position the rotating rod, ensuring smooth rotation. When it is necessary to flatten the two sides marked with arrows on the injection molded parts, it can be accurately flipped to a suitable angle to achieve full processing, improving processing quality and efficiency. At the same time, it ensures the stable and reliable operation of the mechanism and reduces the processing error and the risk of part damage caused by unstable flipping. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0041] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a flattening and shaping mechanism for injection molded parts, including a base 1 and an injection molded part 2. A flipping mechanism 4 is provided at the top of the base 1. The base 1 serves as the basic support structure for the entire flattening and shaping mechanism for injection molded parts, stably supporting all components on it and providing an installation platform for the support frame 6, the flipping mechanism 4, etc., ensuring the stability of each component during operation, preventing the mechanism from shaking or shifting during operation, and ensuring the accuracy of the entire processing process. The injection molded part 2 is the core object of the entire processing process. A support frame 6 is fixedly connected to the top of the base 1, and a flattening machine 7 is slidably connected to the top of the support frame 6. The main function of the support frame 6 is to provide support and guidance for the flattening machine 7. On the one hand, it stably sets the flattening machine 7 in a suitable position so that it remains stable during operation. On the other hand, through the slidable connection with the flattening machine 7, it guides the flattening machine 7 to accurately flatten the injection molded part 2, ensuring the accuracy of the flattening process. A clamping mechanism 3 is fixedly connected to the left end of the flipping mechanism 4.

[0042] Specifically, the base 1 provides a stable foundation for the entire mechanism, ensuring stability when all components work together, preventing shaking and displacement, and guaranteeing the accuracy of the processing. The support frame 6 provides reliable support and precise guidance for the flattening machine 7, enabling the flattening machine 7 to perform flattening operations on the injection molded parts 2 stably and accurately, effectively improving the accuracy and quality of the flattening process. The design of these basic structures lays a solid foundation for subsequent clamping, flipping, and flattening operations.

[0043] The clamping mechanism 3 includes a fixing block 301. The right end of the fixing block 301 is fixedly connected to the left end of the flipping mechanism 4. A motor 302 is fixedly connected inside the fixing block 301. The fixing block 301 is the main support structure of the clamping mechanism 3, providing installation space for components such as the motor 302. At the same time, through its connection with the flipping mechanism 4, it ensures the stability of the clamping mechanism 3 during the flipping process, so that the injection molded part 2 can maintain accurate positioning and no displacement deviation when flipped. The drive end of the motor 302 is fixedly connected to a rotating shaft 303, and the outer wall of the rotating shaft 303 is rotatably connected to the fixing block 301. The inner wall of the clamping mechanism 3 is fixedly connected to the outer side of the rotating shaft 303. The motor 302 serves as the power source for the clamping mechanism 3, providing driving force for the entire clamping action. After starting, it drives the rotating shaft 303 to rotate, thereby driving the gear 304 to rotate. The inner wall of the fixed block 301 is slidably connected to the rack plate 305. The outer side of the rack plate 305 is meshed with the outer side of the gear 304. The gear 304 and the rack plate 305 cooperate with each other to convert the rotational motion of the motor 302 into the linear motion of the rack plate 305. The rotation of the gear 304 pushes the rack plate 305 on the fixed block 301. 1. The rack plate 305 has guide plates 306 fixedly connected to both the upper and lower sides. Guide grooves 307 are provided on the inner walls of both the upper and lower sides of the fixing block 301. The outer wall of the guide plate 306 is slidably connected to the inner wall of the guide groove 307. The guide plate 306 and the guide groove 307 work together to guide and limit the sliding of the rack plate 305. The guide plate 306 slides within the guide groove 307 to prevent the rack plate 305 from shifting or shaking during movement. An L-shaped plate 308 is fixedly connected to the left side of the rack plate 305. The outer wall of the L-shaped plate 308 is slidably connected to the inner wall of the fixing block 301. The inner wall of block 301 has a square plate 309 fixedly connected to the front end of L-shaped plate 308. L-shaped plate 308 connects rack plate 305 and square plate 309, transmitting the linear motion of rack plate 305 to square plate 309 on the left. The front end of fixed block 301 is fixedly connected to another square plate 309. Square plate 309 is in direct contact with injection molded part 2 and is a key component for clamping and positioning. The two square plates 309 move closer or further apart under the action of clamping mechanism 3 to clamp injection molded part 2. Adaptive components are provided inside square plate 309.

[0044] Specifically, the fixing block 301 of the clamping mechanism 3 provides installation space for internal components and ensures the stability of the clamping mechanism 3 during the flipping process, ensuring accurate positioning of the injection molded part 2 during flipping and reducing displacement deviation. The motor 302 serves as a power source, and in conjunction with the transmission of the gear 304 and the rack plate 305, it converts the rotational motion into linear motion, thereby achieving effective clamping of the injection molded part 2. The guide plate 306 and the guide groove 307 guide and limit the rack plate 305, ensuring the smoothness and accuracy of the clamping action, thereby improving the reliability and stability of the clamping.

[0045] Reference Figure 2 and Figure 3 The adaptable components include bolts 311, and a square plate 309 with multiple through holes 310 inside. The outer wall of the bolt 311 is rotatably connected to the inner wall of the through hole 310. A nut 312 is threaded onto the outer side of the bolt 311. A positioning rod 314 is fixedly connected to the left side of the right bolt 311, and a clamping rod 315 is fixedly connected to the right side of the left bolt 311. A positioning hole 5 is opened inside the injection molded part 2. The outer wall of the positioning rod 314 contacts the inner wall of the positioning hole 5, and the right side of the clamping rod 315 contacts the left side of the injection molded part 2. By selecting different positions of the through holes 310 to install the bolts 311 and fixing them with nuts 312, the positioning rod 314 and clamping rod 315 can be flexibly adjusted. The position of the clamping rod 315 is adapted to the positioning and clamping requirements of injection molded parts 2 of different shapes, enhancing the versatility of the clamping mechanism 3. The inner wall of the through hole 310 is provided with a fixing groove 313. The outer wall of the nut 312 engages with the inner wall of the fixing groove 313. The function of the fixing groove 313 is to prevent the nut 312 from loosening after tightening. The positioning rod 314 is inserted into the positioning hole 5 of the injection molded part 2 to achieve precise positioning of the part and ensure the positional accuracy of the part during clamping and processing. After positioning, the clamping rod 315 closely contacts the left side of the injection molded part 2, firmly clamping the part between the two square plates 309 to prevent the part from shifting during processing.

[0046] Specifically, the adapting component, through the cooperation of bolts 311, nuts 312, positioning rods 314 and clamping rods 315, can flexibly adjust the positioning and clamping positions according to the characteristics of injection molded parts 2 of different shapes, greatly enhancing the versatility of the clamping mechanism 3. The positioning rods 314 cooperate with the positioning holes 5 of the injection molded parts 2 to achieve precise positioning, and the clamping rods 315 firmly clamp the parts to prevent displacement of the parts during processing, further improving the accuracy and stability of clamping and positioning parts of different shapes.

[0047] Reference Figure 1 and Figure 2The flipping mechanism 4 includes a protective box 401, the bottom of which is fixedly connected to the top of the base 1. A drive motor is installed inside the protective box 401. The protective box 401 not only protects the internal drive motor and other components from external environmental influences but also provides a certain level of safety protection. A rotating rod 402 is fixedly connected to the drive end of the drive motor. A connecting plate 403 is fixedly connected to the left end of the rotating rod 402. The right end of the fixing block 301 is fixedly connected to the left end of the connecting plate 403. The drive motor provides power for rotation, and the rotating rod 402 transmits the power to the connecting plate 403. The connecting plate 403 drives the clamping mechanism 3 and its clamped components. The injection molded part 2 is flipped to enable processing of different surfaces of the part, improving the comprehensiveness of the processing. A pad 404 is fixedly connected to the top of the base 1, and two support seats 405 are fixedly connected to the top of the pad 404. The outer wall of the rotating rod 402 is rotatably connected to the inner wall of the two support seats 405. During the flipping process, the outer wall of the rotating rod 402 rotates on the inner wall of the two support seats 405 on the pad 404 at the top of the base 1. The two support seats 405 play the role of supporting and positioning the rotating rod 402, ensuring the stability and accuracy of the rotating rod 402 during the flipping process, thereby enabling precise processing of different surfaces of the injection molded part 2 and improving the comprehensiveness and quality of the processing.

[0048] Specifically, the protective box 401 of the flipping mechanism 4 protects the internal drive motor and other components, and also serves as a safety protection function. The drive motor provides power, which drives the clamping mechanism 3 and the injection molded part 2 to flip via the rotating rod 402 and the connecting plate 403, thereby enabling the processing of different surfaces of the part and improving the comprehensiveness of the processing. The support seat 405 on the pad 404 supports and positions the rotating rod 402, ensuring the stability and accuracy of the rotating rod 402 during the flipping process, thereby achieving precise processing of different surfaces of the injection molded part 2 and improving the processing quality.

[0049] Working principle: When it is necessary to clamp the injection molded part 2, the motor 302 inside the fixing block 301 starts and drives the rotating shaft 303 to rotate. The gear 304 on the rotating shaft 303 rotates accordingly. Since the gear 304 meshes with the rack plate 305, the rotation of the gear 304 pushes the rack plate 305 to slide on the inner wall of the fixing block 301. The movement of the rack plate 305 drives the L-shaped plate 308 to move. The square plate 309 fixed at the front end of the L-shaped plate 308 is displaced accordingly. For injection molded parts 2 of different shapes, the through holes 310 are selected at different positions to install screws. Bolt 311 is installed on the left side of the right bolt 311 and clamping rod 315 is installed on the right side of the left bolt 311. During installation, the positioning rod 314 is aligned with the positioning hole 5 on the injection molded part 2. The outer wall of the positioning rod 314 contacts the inner wall of the positioning hole 5 for positioning. Another square plate 309 is also fixed to the front end of the fixing block 301. The left square plate 309 moves to the right and gradually approaches the right square plate 309, so that the right side of the clamping rod 315 is in close contact with the left side of the injection molded part 2, thus completing the precise positioning and stable clamping of the injection molded part 2.

[0050] The drive motor inside the protective box 401 starts, and the drive end drives the rotating rod 402 to rotate. The outer wall of the rotating rod 402 rotates on the inner wall of the two support seats 405 on the top pad 404 of the base 1 to ensure rotational stability. The connecting plate 403 connected to the left end of the rotating rod 402 rotates accordingly. The left end of the connecting plate 403 is fixedly connected to the fixing block 301 of the clamping mechanism 3. When it is necessary to flip the injection molded part 2, the drive motor runs according to the set program, driving the rotating rod 402 to rotate smoothly, thereby causing the connecting plate 403 and the fixing block 301 to rotate around the axis of the rotating rod 402, realizing the flipping of the clamping mechanism 3 and the injection molded part 2, so as to flatten the two sides marked by the arrow on the injection molded part 2.
