Description

Technical Field

[0001] This utility model relates to the field of shearing device technology, and in particular to a shearing device for burrs on injection molded parts. Background Technology

[0002] Injection molded parts are plastic products formed by heating and melting plastic granules, then pushing them into a pre-designed mold cavity through the screw or plunger of an injection molding machine, and finally cooling and solidifying them. After injection molding, the surface of the injection molded parts is prone to having burrs, which will affect the subsequent use of the injection molded parts. Therefore, it is necessary to use a shearing device to remove the burrs from the injection molded parts.

[0003] A patent document with publication number CN218227520U discloses a device for trimming burrs on automotive injection molded parts. The device includes a housing with a fixing mechanism. Two support plates are fixed to the upper surface of the housing, and a top box is fixed to the upper surface of the two support plates. A trimming mechanism is mounted on the top box. The fixing mechanism includes a first motor fixed to the upper surface of the housing cavity. A first screw is fixed to the output shaft of the first motor, and a lifting plate is threaded onto the outer surface of the first screw. This device, with its fixing mechanism, uses the first motor and the first screw to raise and lower the lifting plate, which in turn raises and lowers the clamping plate. An electric push rod pushes a moving block, which in turn moves the clamping plate, thus fixing the automotive injection molded parts on the placement plate and facilitating burr trimming. Compared to traditional methods, this device is more convenient and has a wider range of applications.

[0004] The above-mentioned and existing technologies have the following drawbacks: when processing the burrs on the surface of tubular injection molded parts, the burrs are distributed on the end faces, inner circumference and outer circumference. Existing shearing devices need to perform individual shearing operations on these parts one by one, which seriously limits the practicality of the shearing device.

[0005] Therefore, a device for cutting burrs on injection molded parts is proposed. Utility Model Content

[0006] The purpose of this invention is to solve the problem that existing shearing devices require separate shearing operations on the two end faces, inner circumferential surface and outer circumferential surface of tubular injection molded parts, and to propose a burr shearing device for injection molded parts.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a burr shearing device for injection molded parts, comprising a processing table, a fixed tube fixedly connected to the upper surface of the processing table, a sliding tube slidably connected to the inner wall of the fixed tube, a mounting plate fixedly connected to the upper end of the sliding tube, a first electric push rod fixedly connected to the outer wall of the fixed tube, the output end of the first electric push rod fixedly connected to the mounting plate, a motor fixedly connected to the upper surface of the mounting plate, a first cutter fixedly connected to the output end of the motor, a sleeve slidably fitted onto the surface of the first cutter, a second cutter fixedly connected to the surface of the sleeve, and a bolt abutting against the surface of the first cutter connected to the internal thread of the sleeve.

[0008] The effect achieved by the above-mentioned components is that, by setting a first cutter and two second cutters, when processing the burrs on the surface of the tubular injection molded part, the burrs on multiple surfaces of the tubular injection molded part can be cut simultaneously by adjusting the direction of the second cutter blade, thus improving the practicality of the cutting device.

[0009] Preferably, a second electric actuator is fixedly connected to the upper surface of the processing table, and a clamping plate is fixedly connected to the output end of the second electric actuator.

[0010] The effect achieved by the above components is: to activate the second electric actuator to push the clamping plate to move closer to the tubular injection molded part in order to clamp the tubular injection molded part.

[0011] Preferably, the cross-section of the clamp is "V" shaped.

[0012] The effect achieved by the above components is that by setting the cross-section of the clamping plate to a "V" shape, the tubular injection molded part can be better clamped, making the tubular injection molded part coaxial with the motor.

[0013] Preferably, a plurality of anti-slip strips are fixedly connected to the surface of the clamp.

[0014] The effect achieved by the above components is that the anti-slip strip can increase the friction between the clamping plate and the tubular injection molded part, thereby improving the clamping stability.

[0015] Preferably, a round rod is fixedly connected to the surface of the clamping plate, and a round tube is fixedly connected to the upper surface of the processing table, with the round rod sliding through the round tube.

[0016] The effect achieved by the above components is that the sliding of the round rod along the round tube ensures the smooth movement of the clamping plate.

[0017] Preferably, guide plates are fixedly connected to both ends of the first cutter.

[0018] The effect achieved by the above components is that, during the adjustment of the second cutter, the square plate can re-attach the removed sleeve to the surface of the first cutter.

[0019] Preferably, two fixed rods are fixedly connected to the upper surface of the processing table, and a baffle is slidably fitted on the circumferential surface of the fixed rods. A third electric push rod is fixedly connected to the lower surface of the processing table, and a movable plate is fixedly connected to the output end of the third electric push rod. The movable plate slides through the processing table, and the movable plate is slidably connected to the baffle.

[0020] The effect achieved by the above components is that the moving plate and the baffle can block the flying debris generated by shearing, limit the distribution range of the debris, and facilitate the subsequent centralized processing of the debris.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting a first cutter and two second cutters, when processing burrs on the surface of a tubular injection molded part, the direction of the second cutter blade can be adjusted to simultaneously cut burrs on multiple surfaces of the tubular injection molded part, thus improving the practicality of the cutting device.

Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] like Figures 1-5 As shown, this utility model provides a burr shearing device for injection molded parts, including a processing table 1. A fixed tube 2 is fixedly connected to the upper surface of the processing table 1. A sliding tube 3 is slidably connected to the inner wall of the fixed tube 2. A mounting plate 5 is fixedly connected to the upper end of the sliding tube 3. A first electric push rod 4 is fixedly connected to the outer wall of the fixed tube 2. The output end of the first electric push rod 4 is fixedly connected to the mounting plate 5. A motor 6 is fixedly connected to the upper surface of the mounting plate 5. A first cutter 7 is fixedly connected to the output end of the motor 6. A sleeve 8 is slidably fitted onto the surface of the first cutter 7. A second cutter 9 is fixedly connected to the surface of the sleeve 8. A bolt 10 is threaded into the sleeve 8 and abuts against the surface of the first cutter 7. By setting the first cutter 7 and two second cutters 9, when processing the burrs on the surface of the tubular injection molded part, the burrs on multiple surfaces of the tubular injection molded part can be sheared simultaneously by adjusting the direction of the blade of the second cutter 9, thus improving the practicality of the shearing device.

[0027] like Figure 3 and Figure 4 As shown, a second electric push rod 11 is fixedly connected to the upper surface of the processing table 1. A clamping plate 12 is fixedly connected to the output end of the second electric push rod 11. When the second electric push rod 11 is activated, it pushes the clamping plate 12 to move closer to the tubular injection molded part to clamp the tubular injection molded part. The cross-section of the clamping plate 12 is "V" shaped. Setting the cross-section of the clamping plate 12 to "V" shape can better clamp the tubular injection molded part and make the tubular injection molded part coaxial with the motor 6. Several anti-slip strips 13 are fixedly connected to the surface of the clamping plate 12. The anti-slip strips 13 can increase the friction between the clamping plate 12 and the tubular injection molded part and improve the clamping stability. A round rod 14 is fixedly connected to the surface of the clamping plate 12. A round tube 15 is fixedly connected to the upper surface of the processing table 1. The round rod 14 slides through the round tube 15. The sliding of the round rod 14 along the round tube 15 can ensure that the clamping plate 12 moves smoothly.

[0028] like Figure 3 and Figure 4As shown, guide plates 20 are fixedly connected to both ends of the first cutter 7. During the adjustment of the second cutter 9, the guide plates 20 allow the removed sleeve 8 to be re-attached to the surface of the first cutter 7. Two fixed rods 16 are fixedly connected to the upper surface of the processing table 1. A baffle 17 is slidably fitted on the circumferential surface of the fixed rods 16. A third electric push rod 18 is fixedly connected to the lower surface of the processing table 1. A moving plate 19 is fixedly connected to the output end of the third electric push rod 18. The moving plate 19 slides through the processing table 1 and is slidably connected to the baffle 17. The cooperation between the moving plate 19 and the baffle 17 can block the flying debris generated by shearing, limit the distribution range of the debris, and facilitate subsequent centralized processing of the debris.

[0029] The overall working principle is as follows: when processing the burrs on the surface of the tubular injection molded part, the tubular injection molded part is first placed on the processing table 1. The second electric push rod 11 is activated to push the clamping plate 12 towards the tubular injection molded part to clamp it. The anti-slip strip 13 can increase the friction between the clamping plate 12 and the tubular injection molded part, thereby improving the clamping stability. By setting the cross-section of the clamping plate 12 into a "V" shape, the tubular injection molded part can be clamped better, making the tubular injection molded part coaxial with the motor 6. The round rod 14 slides along the round tube 15. The movement ensures the smooth movement of the clamping plate 12. Then, the bolt 10 is rotated to loosen the sleeve 8, and the sleeve 8 is slid to adjust the position of the second cutter 9. During this process, when the blades of the two second cutters 9 are close to each other, they can shear the burrs on the outer circumference of the tubular injection molded part. When the blades of the two second cutters 9 are far apart, they can shear the burrs on the inner circumference of the tubular injection molded part. When the blades of the two second cutters 9 are facing different directions, they can... The first cutter 7 and two second cutters 9 are respectively positioned to abut against the inner and outer circumferential surfaces of the tubular injection molded part, thereby simultaneously shearing the burrs on both surfaces. Therefore, with the cooperation of the first cutter 7 and two second cutters 9, burrs on multiple surfaces of the tubular injection molded part can be sheared simultaneously. During the adjustment of the second cutters 9, the guide plate 20 allows the square plate to re-attach the removed sleeve 8 to the surface of the first cutter 7. After adjusting the second cutters 9, the bolts 10 are tightened to secure the sleeve 8, and then the first electric actuator 4 is activated to push the mounting plate. 5. The blade descends, bringing the first cutter 7 into contact with the upper surface of the tubular injection molded part. Then, the motor 6 is started to drive the first cutter 7 to rotate. The first cutter 7 simultaneously drives the second cutter 9 to cut the burrs on the circumference of the tubular injection molded part. During the cutting process, the third electric push rod 18 can also be activated to push the moving plate 19 upward and drive the baffle 17 to slide along the fixed rod 16 to a suitable height. The moving plate 19 and the baffle 17 work together to block the flying debris generated by the cutting, limit the distribution range of the debris, and facilitate the subsequent centralized processing of the debris.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
