Description

Technical Field

[0001] This utility model relates to the field of injection molding production and automated assembly technology, and in particular to an automated clamping mechanism for injection molding. Background Technology

[0002] In the injection molding production field, the application of automated equipment is becoming increasingly widespread, significantly improving production efficiency, reducing labor costs, and enhancing product quality. However, in the subsequent assembly process of injection molded parts, especially in the snap-fit ​​installation stage, there is still considerable room for technological improvement. Traditional snap-fit ​​installation methods mostly rely on manual operation or semi-automatic equipment. This approach is not only inefficient but also prone to insufficient installation accuracy due to human factors, affecting the assembly quality of the product. Furthermore, existing automated snap-fit ​​installation equipment generally suffers from complex structures, difficult debugging, and poor applicability, making it difficult to meet the needs of rapid production switching for different specifications and types of injection molded parts. Simultaneously, in actual production, due to the diverse shapes of injection molded parts and varying snap-fit ​​positions and installation force requirements, existing equipment often cannot flexibly cope, resulting in insufficient production adaptability and stability. Therefore, developing a mechanism that is simple in structure, easy to operate, and capable of efficiently completing automatic snap-fit ​​installation has become a pressing technical challenge in the field of injection molding automation. This utility model addresses the above problems by proposing an automated snap-fit ​​installation mechanism for injection molding, achieving efficient, precise, and flexible snap-fit ​​installation operations.

[0004] This utility model is implemented as follows: an automated injection molding clamping mechanism includes a base, a drive housing on one side of the top of the base, and a clamping housing with open top and bottom. A support plate is fixedly mounted on the other side of the top of the base. A series of spaced slide rails are fixed between the drive housing and the support plate. The clamping housing is located between the slide rails. The output end of the drive housing is a crank-connecting rod structure connected to the clamping housing. The drive housing is used to drive the clamping housing to reciprocate on the slide rails via the crank-connecting rod structure. An inclined guide groove is fixedly connected to the base, located at the bottom of the clamping housing. A positioning component is also included. The positioning component is located inside the clamping housing and includes a turntable rotatably mounted inside the clamping housing. The turntable has multiple evenly arranged clamping slots. The positioning component further includes two arc-shaped limiting blocks and two inclined limiting blocks. The two arc-shaped limiting blocks are spaced apart along the axial direction of the turntable and fixedly connected to the inner walls of both sides of the mounting box. The two inclined limiting blocks are spaced apart along the radial direction of the turntable and fixedly connected to the inner walls of both sides of the mounting box. The height of both the arc-shaped limiting blocks and the inclined limiting blocks is greater than the height of the turntable axis. Both the arc-shaped limiting blocks and the inclined limiting blocks cooperate with the surface of the turntable. The arc-shaped limiting blocks, the inclined limiting blocks, the top surface of the turntable, and the inner wall of the mounting box form a latching compartment. Both sides of the mounting box are provided with main pulleys that cooperate with two slide rails. The main pulleys are provided with a pawl structure with directional rotation function. The main pulleys and the turntable are connected by a reducer fixedly installed on the outer surface of the mounting box.

[0005] Preferably, a secondary housing is fixedly connected to the side of the loading box away from the drive box, and secondary pulleys that cooperate with the slide rail frame are rotatably arranged on both sides of the secondary housing. The secondary housing, secondary pulleys, main pulleys and turntable are all in the same plane.

[0006] Preferably, a rectangular opening is provided at the joint between the loading box and the sub-box. A vertically arranged guide post is fixedly connected inside the sub-box, and a horizontally arranged push rod is slidably connected to the guide post. A clamping block is fixedly connected to one end of the push rod facing the rectangular opening, and a double-end frame is connected to the other end of the push rod. Pins are fixedly connected to both ends of the double-end frame. Turntables connected to the auxiliary pulley are provided on both sides of the sub-box. Elliptical grooves that cooperate with the pins are provided on the turntables. When the loading box moves back and forth, the clamping block at one end of the push rod moves back and forth through the cooperation of the turntable and the pin, so that it contacts the surface of the turntable.

[0007] Preferably, an elastic sealing layer is fixedly connected to the push rod, and the elastic sealing layer is sealed to the inner wall of the sub-box. The elastic sealing layer is located between the guide post and the clamping block. The elastic sealing layer isolates the internal space of the sub-box into a dust-free chamber.

[0011] The present invention provides an automated injection molding clamping mechanism with the following advantages: The driving method of this device is the same as that of conventional clamping installation equipment, both utilizing the rapid reciprocating motion of the clamping box to achieve clamp positioning and clamping. The key difference lies in the use of the reciprocating motion of the clamping box, combined with a conventional reducer and a pawl structure on the main pulley, to enable the turntable inside the clamping box to rotate slowly. This slow rotation not only allows for the switching of clamping slot areas on the turntable, but also, due to the turntable's structural characteristics, allows the clamp to undergo two positioning processes. Once the clamping slot areas on the turntable can rotate and switch, even if clamp misalignment occurs, a new clamping slot area can be switched to handle the positioning work. This rotational switching method not only reduces the frequency of turntable adjustments but also makes adjustments easier. In summary, this clamping mechanism, through the cooperation of simple mechanical structures, achieves positioning while also featuring low adjustment frequency and simplified adjustment.

[0018] This utility model provides an automated clamping mechanism for injection molding, the specific implementation of which is as follows (in conjunction with the attached diagram). Figure 1 To be continued Figure 4 A detailed description is provided below. In this embodiment, the device includes a base 1, a drive housing 2, a clamping housing 3, a slide rail frame 4, a positioning assembly, and a guide chute 7, among other main components. The cooperation between these components achieves precise positioning and efficient clamping of the latches. Simultaneously, the optimized design of the mechanical structure enhances the stability and ease of adjustment of the equipment. The following will elaborate on the specific implementation of this utility model from the aspects of overall structural layout, the functions of key components, and operating principles.

[0019] like Figure 1 As shown, the base 1 serves as the fundamental support for the entire device. A drive housing 2 is fixedly mounted on one side of its top, while a support plate 5 is fixedly connected to the other side. The support plate 5 and the drive housing 2 are connected via a slide rail frame 4. The slide rail frame 4 consists of two spaced guide rails used to guide the reciprocating movement of the clamping housing 3. The clamping housing 3 is located between the slide rail frames 4, with open tops and bottoms to facilitate the feeding and discharging of the clips. The output end of the drive housing 2 is connected to the clamping housing 3 via a crank-connecting rod structure 6. When the drive housing 2 operates, the crank-connecting rod structure 6 drives the clamping housing 3 to reciprocate rapidly along the slide rail frame 4. This reciprocating motion is the core power source for achieving clip positioning and clamping operations. Furthermore, an inclined guide trough 7 is fixedly connected to the base 1. The guide trough 7 is located at the bottom of the clamping housing 3 and is used to guide the clips from the external supply device to the positioning assembly inside the clamping housing 3.

[0020] The positioning component inside the card box 3 is a key part of this utility model, and its specific structure is as follows: Figure 2As shown. The positioning assembly mainly includes a turntable 8, an arc-shaped limiting block 9, an inclined limiting block 10, and related transmission and limiting structures. The turntable 8 is rotatably mounted inside the mounting box 3 via bearings. Its surface has multiple evenly arranged snap-fit ​​slots for accommodating and initially positioning the snap-fits. The arc-shaped limiting block 9 and the inclined limiting block 10 are spaced apart along the axial and radial directions of the turntable 8, respectively, and are fixedly connected to the inner walls of both sides of the mounting box 3. The heights of both the arc-shaped limiting block 9 and the inclined limiting block 10 are greater than the height of the axis of the turntable 8, and both are tightly fitted to the surface of the turntable 8, thus forming a closed snap-fit ​​chamber. This snap-fit ​​chamber, composed of the arc-shaped limiting block 9, the inclined limiting block 10, the top surface of the turntable 8, and the inner walls of the mounting box 3, ensures the precise positioning and stability of the snap-fits on the turntable 8. In addition, main pulleys 11 are provided on both sides of the loading box 3. The main pulleys 11 cooperate with the slide rail frame 4 to support the loading box 3 and reduce its frictional resistance during reciprocating motion. A pawl structure 12 is provided on the main pulleys 11. This pawl structure 12 has a directional rotation function, which can convert the reciprocating linear motion of the loading box 3 into the slow rotational motion of the turntable 8. Specifically, the main pulleys 11 and the turntable 8 are connected by a reducer 13. When the loading box 3 reciprocates along the slide rail frame 4, the main pulleys 11 drive the reducer 13 through the pawl structure 12, thereby driving the turntable 8 to rotate slowly. This design allows the turntable 8 to switch to a new latching slot area after each reciprocating motion, thus achieving multiple positioning processes for the latches.

[0021] To further enhance the functionality and adaptability of the device, a secondary housing 14 is also fixedly connected to one side of the mounting housing 3, such as... Figure 2As shown. Secondary pulleys 15 are rotatably mounted on both sides of the secondary housing 14. These pulleys 15 cooperate with the slide rail frame 4 to assist in the smooth movement of the mounting housing 3. A rectangular opening 16 is provided at the junction of the secondary housing 14 and the mounting housing 3, accommodating the push rod 18 and its related components. A vertically mounted guide post 17 is fixedly connected inside the secondary housing 14. A horizontally mounted push rod 18 is slidably connected to the guide post 17. One end of the push rod 18 is fixedly connected to a clamping block 19, and the other end is connected to a double-end frame 20. Pins 21 are fixedly connected to both ends of the double-end frame 20. Turntables connected to the secondary pulleys 15 are provided on both sides of the secondary housing 14. Elliptical grooves 22 are provided on the turntables, cooperating with the pins 21. When the mounting box 3 reciprocates, the auxiliary pulley 15 drives the turntable to rotate via a transmission connection. The elliptical groove 22 on the turntable, in conjunction with the pin 21, causes the double-end frame 20 to reciprocate, which in turn pushes the clamping block 19 at one end of the push rod 18 to reciprocate. The clamping block 19 contacts the surface of the turntable 8 to clamp the buckle, ensuring the stability of the buckle during positioning. An elastic sealing layer 23 is also fixedly connected to the push rod 18. The elastic sealing layer 23 is sealed to the inner wall of the auxiliary box 14, thereby isolating the internal space of the auxiliary box 14 into a cleanroom. Both the double-end frame 20 and the turntable are located within the cleanroom to avoid the influence of external dust on the transmission components. In addition, air passages 24 are provided inside both the clamping block 19 and the push rod 18. Multiple air holes 25 are provided on one side of the clamping block 19. An air outlet pipe 26 connected to the air passage 24 is fixedly connected to the double-end frame 20. An air inlet pipe 27 is fixedly provided on the top of the auxiliary housing 14. One-way valves are provided on both the air outlet pipe 26 and the air inlet pipe 27. A dust cover 28 is fixedly connected to the top of the air inlet pipe 27. This air passage design can clean the dust or impurities on the surface of the buckle through the airflow during the reciprocating movement of the clamping block 19, thereby ensuring the cleanliness of the buckle and the assembly quality.

[0022] like Figure 3 As shown, a box 29 is fixedly connected to the side of the mounting box 3 opposite to the rectangular opening 16. An industrial control camera 30 is installed inside the box 29 to monitor the positioning and clamping status of the clips in real time. A transparent window 31 is fixedly installed at the joint between the box 29 and the mounting box 3, allowing the industrial control camera 30 to photograph and analyze the interior of the mounting box 3 through the transparent window 31. Electromagnetic clutches 32 are fixedly connected to both sides of the auxiliary box 14. The electromagnetic clutches 32 control the transmission connection between the auxiliary pulley 15 and the turntable, thereby achieving precise control of the movement of the clamping block 19. Furthermore, a discharge door 33, which can be closed or opened, is provided on one side of the clip compartment in the mounting box 3. The discharge door 33 is used to discharge the clips from the mounting box 3 after the positioning and clamping operations are completed.

[0023] The working principle of this utility model is as follows: First, the buckle enters the buckle compartment inside the mounting box 3 through the guide groove 7. The arc-shaped limiting block 9 and the inclined limiting block 10 initially position the buckle. Subsequently, the drive box 2 drives the mounting box 3 to reciprocate along the slide rail frame 4 through the crank connecting rod structure 6. The pawl structure 12 on the main pulley 11 converts the reciprocating motion of the mounting box 3 into the slow rotation motion of the turntable 8, so that the buckle slot area on the turntable 8 is gradually switched. During this process, the industrial control camera 30 monitors the positioning status of the buckle in real time through the transparent window 31 and feeds the data back to the control system. When the buckle enters the final positioning position, the auxiliary pulley 15 drives the turntable to rotate through the transmission connection. The cooperation between the elliptical groove 22 on the turntable and the pin 21 causes the double-end frame 20 to push the clamping block 19 at one end of the push rod 18 to perform a clamping operation. The clamping block 19 contacts the surface of the turntable 8 to ensure the stability of the buckle during the positioning process. Meanwhile, the air system cleans dust or impurities from the buckle surface through the air inlet pipe 27 and the air outlet pipe 26, thus ensuring the cleanliness of the buckle. Finally, after the buckle completes the positioning and clamping operation, the discharge chamber door 33 opens, and the buckle is discharged from the mounting box 3, completing the entire assembly process.

[0024] In summary, through reasonable mechanical structure design and optimized configuration of functional modules, this utility model not only achieves precise positioning and efficient clamping of the buckle, but also significantly reduces the frequency and difficulty of adjustment, thus possessing high practical value and promising prospects for promotion.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
