Description

Technical Field

[0001] This invention relates to the field of injection molding equipment technology, specifically to an injection molding part end corner grinding and trimming adjustment device. Background Technology

[0002] The injection molding part corner grinding and trimming equipment is mainly used to grind and trim defects such as gates, flash, burrs, sharp corners, sharp edges, and parting lines that occur after injection molding. This ensures the consistency of the corner dimensions of the injection molding parts, removes sharp edges to avoid scratching during assembly and use, and improves the appearance smoothness, thereby eliminating the impact of flash and burrs on assembly accuracy and product strength.

[0003] However, existing injection molding part corner grinding equipment is not convenient for quickly and accurately adjusting the grinding positioning angle according to the grinding requirements of the injection molding part, which reduces the adaptability of the equipment to grinding different injection molding part corners. Therefore, an injection molding part corner grinding and trimming adjustment device is needed to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a grinding and trimming adjustment device for the end corners of injection molded parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grinding and trimming adjustment device for the end corners of injection molded parts, comprising a support base, two sets of mating plates fixedly disposed on the upper part of the support base, an annular guide seat fixedly disposed on the upper part of the support base via the two sets of mating plates, and a servo motor fixedly disposed on the front part of the support base via a motor mount.

[0006] A grinding and trimming assembly is rotatably engaged with the inner end face of an annular guide seat, and the power output end of the servo motor drives the grinding and trimming assembly to mesh and rotate inside the annular guide seat through the drive gear. The grinding and trimming assembly is used for grinding and trimming.

[0007] The feeding assembly is fixedly installed on the top of the support base, and five sets of injection molded parts are fixedly clamped at equal intervals on the inner end face of the feeding assembly. The feeding assembly is used to feed the injection molded parts at equal intervals into the interior of the grinding and trimming assembly.

[0008] Specifically, the grinding and trimming assembly includes a driven gear ring, a limiting seat fixedly disposed on the inner end face of the driven gear ring, and a first stepper motor fixedly disposed on the top of the inner end face of the limiting seat. The power output end of the first stepper motor is threadedly connected to a threaded slide block via a guide screw, and a support guide is fixedly disposed on the lower end face of the threaded slide block via two sets of linear sliding shafts. A second stepper motor is fixedly disposed in the middle of the inner end face of the support guide block, and a grinding turntable is disposed at the power output end of the second stepper motor.

[0009] Specifically, the feeding assembly includes a support bracket, a second servo motor fixedly mounted at the rear of the support bracket, and two sets of linear slide rails fixedly mounted on the upper part of the inner end face of the support bracket. The power output end of the second servo motor is threadedly connected to a material guiding assembly via a transmission screw.

[0010] Specifically, the material guiding assembly includes a positioning slide, two sets of linear sliders fixedly disposed on the lower end face of the positioning slide, and a threaded guide fixedly disposed at the center of the lower end face of the positioning slide. Five sets of wide air grippers are equidistantly disposed on the upper end face of the positioning slide, and locking clamps are fixedly disposed on both output ends of the wide air grippers.

[0011] Specifically, the output end of the servo motor engages with the driven gear ring via a drive gear, thereby driving the limit holder to rotate inside the annular guide seat. This allows for quick and precise control of the angle at which the grinding turntable trims and grinds the injection molded parts, improving the adaptability of the equipment.

[0012] Specifically, the bottom of the limiting bracket is equipped with two sets of linear bearings, and the stepper motor is adapted to the threaded slide through the guide screw and the linear bearing is adapted to the linear slide shaft, thereby driving the support guide to move in the lower part of the limiting bracket. This can effectively improve the accuracy of the threaded slide driving the support guide and the grinding turntable to move down for trimming and grinding, thereby improving the accuracy of the subsequent grinding turntable for trimming and grinding the injection molded parts.

[0013] Specifically, the second servo motor is adapted to the threaded guide seat through the transmission screw, thereby driving the positioning slide to perform threaded displacement on the upper part of the support bracket. This facilitates the subsequent adjustment of the feeding progress of the injection molded part with the grinding turntable, and improves the overall trimming and grinding efficiency of the injection molded part.

[0014] Specifically, the bottom of the positioning slide block is slidably engaged with the linear slide rail via a linear slider, which can improve the stability of subsequent equipment for grinding and trimming injection molded parts.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This invention is an angle-adjustable injection molding part grinding mechanism. When adjusting the end angle of the injection molding part at different angles, the servo motor can drive the driven gear ring to rotate circumferentially through the active gear, so that the grinding turntable can be offset and positioned at any angle with the grinding point of the injection molding part as the center. This facilitates subsequent grinding and trimming of the end angle of the workpiece from different angles, effectively improving the adaptability of the equipment to grinding the edges and corners of different injection molding parts at different angles, thereby improving the practical performance of the equipment.

[0017] 2. By setting up a grinding and trimming assembly and a feeding assembly, this invention enables the servo motor 2 to be threadedly connected to the threaded guide seat via a transmission screw during the grinding of the injection molded part. This allows for precise control of the grinding feed distance of the injection molded part, thereby improving the accuracy of the subsequent grinding turntable grinding the injection molded part. Furthermore, the stepper motor 1 can be threadedly connected to the threaded slide via a guide screw, thereby quickly and accurately adjusting the grinding intensity and depth of the grinding turntable on the edges and corners of the injection molded part. This effectively improves the accuracy and stability of the equipment in grinding the injection molded part. Attached Figure Description

It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0030] The invention will be further described below with reference to the accompanying drawings.

[0031] Example 1

[0032] Please see Figure 1-8 One embodiment of the present invention provides a grinding and trimming adjustment device for the end corners of injection molded parts, comprising a support base 7, two sets of mating plates 8 fixedly disposed on the upper part of the support base 7, an annular guide seat 9 fixedly disposed on the upper part of the support base 7 via the two sets of mating plates 8, and a servo motor 4 fixedly disposed at the front of the support base 7 via a motor base 5.

[0033] Grinding and trimming assembly 2 is rotatably engaged with the inner end face of the annular guide seat 9, and the power output end of the servo motor 4 drives the grinding and trimming assembly 2 to mesh and rotate inside the annular guide seat 9 through the drive gear 6. The grinding and trimming assembly 2 is used for grinding and trimming.

[0034] The feeding assembly 3 is fixedly installed on the top of the support base 7, and five sets of injection molded parts 1 are fixedly clamped at equal intervals on the inner end face of the feeding assembly 3. The feeding assembly 3 is used to feed the injection molded parts 1 at equal intervals into the interior of the grinding and trimming assembly 2.

[0035] like Figure 3 and Figure 4 The grinding and trimming assembly 2 includes a driven gear ring 29, a limiting seat 24 fixedly disposed on the inner end face of the driven gear ring 29, and a stepper motor 23 fixedly disposed on the top of the inner end face of the limiting seat 24. The power output end of the stepper motor 23 is threadedly connected to a threaded slide 21 through a guide screw 25, and a support guide 26 is fixedly disposed on the lower end face of the threaded slide 21 through two sets of linear slide shafts 22. A second stepper motor 27 is fixedly disposed in the middle of the inner end face of the support guide 26, and a grinding turntable 28 is disposed at the power output end of the second stepper motor 27.

[0036] like Figure 5 and Figure 6 The feeding assembly 3 includes a support bracket 33, a servo motor 34 fixedly installed at the rear of the support bracket 33, and two sets of linear slide rails 31 fixedly installed on the upper part of the inner end face of the support bracket 33. The power output end of the servo motor 34 is threadedly connected to the guide assembly 32 through the transmission screw 35.

[0037] like Figure 7 and Figure 8 The material guiding assembly 32 includes a positioning slide 323, two sets of linear sliders 321 fixedly disposed on the lower end face of the positioning slide 323, and a threaded guide seat 325 fixedly disposed at the center of the lower end face of the positioning slide 323. Five sets of wide pneumatic grippers 322 are equidistantly disposed on the upper end face of the positioning slide 323, and locking clamps 324 are fixedly disposed on both output ends of the wide pneumatic grippers 322.

[0038] The output end of the servo motor 4 meshes with the driven gear ring 29 through the drive gear 6, thereby driving the limit holder 24 to rotate inside the annular guide seat 9. This not only improves the stability of the transmission between the drive gear 6 and the driven gear ring 29, but also allows for quick and precise control of the angle of the grinding turntable 28 for trimming and grinding the injection molded part 1, thus improving the adaptability of the equipment.

[0039] Two sets of linear bearings are provided at the bottom of the limiting bracket 24. The stepper motor 23 is adapted to the threaded slide 21 through the guide screw 25 and the linear bearing is adapted to the linear slide shaft 22, thereby driving the support guide 26 to move at the bottom of the limiting bracket 24. The sliding limit of the linear bearing and the linear slide shaft 22 can effectively improve the stability of the subsequent axial up and down displacement of the support guide 26 at the bottom of the limiting bracket 24. At the same time, the threaded connection between the guide screw 25 and the threaded slide 21 can effectively improve the accuracy of the threaded slide 21 driving the support guide 26 and the grinding turntable 28 to move down for trimming and grinding, thereby improving the accuracy of the subsequent trimming and grinding of the injection molded part 1 by the grinding turntable 28.

[0040] Servo motor 34 is adapted to threaded guide seat 325 through transmission screw 35, thereby driving positioning slide 323 to perform threaded displacement on the upper part of support bracket 33. The threaded connection between transmission screw 35 and threaded guide seat 325 can improve the accuracy and stability of the equipment for feeding and guiding injection molded part 1, and also facilitate the subsequent adjustment of the feeding progress of injection molded part 1 with grinding turntable 28, thereby improving the overall trimming and grinding efficiency of injection molded part 1.

[0041] The bottom of the positioning slide 323 is slidably engaged with the linear slide rail 31 via the linear slider 321, which can effectively improve the stability of the subsequent material feeding and guiding of the positioning slide 323 on the upper part of the support bracket 33, and improve the stability of the subsequent equipment for grinding and trimming the injection molded part 1.

[0042] Working principle: Before use, the operator can position a batch of injection molded parts 1 onto the upper part of the wide-type pneumatic gripper 322 using an external robotic arm. At this time, the injection molded parts 1 can be positioned between two sets of locking clamps 324. Subsequently, the wide-type pneumatic gripper 322 can clamp and limit the injection molded parts 1 through the locking clamps 324, thereby completing the loading and locking operation. When grinding and trimming the injection molded parts 1, the operator can adjust the trimming angle according to the specific injection molded parts 1. During adjustment, the servo motor 4 can be started through the touch screen module. At this time, the servo motor 4 can drive the drive gear 6 to rotate. At the same time, the drive gear 6 can be connected to the driven gear ring 29 through meshing, thereby synchronously driving the limit card seat 24 to rotate inside the annular guide seat 9, thus facilitating the subsequent positioning of the grinding turntable 28 to the upper corner of the injection molded parts 1. The system can simultaneously position the injection molded part 1 at any angle. After positioning, the touch screen module can start the second servo motor 34. At this time, the second servo motor 34 can be connected to the threaded guide seat 325 through the transmission screw 35, thereby driving the positioning slide 323 to carry the injection molded part 1 to the bottom of the grinding turntable 28. During grinding and trimming, the first stepper motor 23 can be connected to the threaded slide seat 21 through the guide screw 25, thereby pushing the support guide seat 26 to move down precisely. At the same time, the second stepper motor 27 can drive the grinding turntable 28 to rotate at a high speed, so that the grinding turntable 28 can perform all-round grinding and trimming operations on the edges and corners of the injection molded part 1. Then, the second servo motor 34 can continue to push the injection molded part 1 to feed material through the transmission screw 35 until the grinding and trimming operations of all injection molded parts 1 are completed.
