[0022] In the production of injection molded parts, flash often refers to the phenomenon of burrs, overflow, and overflow that appear on the edge of the mold during the molding process, which mostly occurs at the parting and closing points of the mold.

[0023] During the injection molding process, improper injection molding techniques, such as excessively fast injection speed, excessively high injection pressure, or excessively long holding time, often lead to overfilling of plastic material at the mold parting line, forming slubs. Inadequate mold design, such as an inaccurate parting line, can also cause slubs. Excessive mold clearance can lead to overfilling at the parting line, resulting in slubs, and can also cause plastic material to overflow during injection, forming slubs. Wear and tear on the mold after prolonged use can also increase the clearance, leading to slub formation in the injection molded parts. This reduces the quality of the injection molded parts. Slub removal is often done manually, resulting in low production efficiency.

[0024] This utility model proposes a chamfering device.

[0025] Please see Figure 1 , Figure 2 and Figure 3In one embodiment of this utility model, the chamfering device includes a base 1, a pushing mechanism 2, a fixing structure 3, and a chamfering mechanism 4. The base 1 forms a chamfering working position; the pushing mechanism 2 includes a supporting part 21, which is disposed at the upper end of the base 1 and can be positioned in the chamfering working position; the fixing structure 3 is used to fix the product 6 to be chamfered at the chamfering working position onto the supporting part 21, and such that the chamfered side of the product 6 extends along a first horizontal direction; and the chamfering mechanism 4 includes a chamfering blade 41, which can move linearly relative to the base 1 along the first horizontal direction and can rotate along an axis extending along the first horizontal direction to remove the chamfered side of the product 6 during the stroke of the chamfering blade 41.

[0026] In the technical solution of this utility model, after the product 6 to be chamfered is installed on the support part 21 and the support part 21 is placed in the chamfering working position, the product 6 to be chamfered is fixed on the support part 21 by the fixing structure 3, and the chamfering side of the product 6 to be chamfered extends along the first horizontal direction; then, through the chamfering mechanism 4, the chamfering blade 41 moves linearly along the first horizontal direction while rotating along the axis extending in the first horizontal direction; during the rotation and linear movement, the chamfering blade 41 can remove the chamfering side of the product 6 to be chamfered, so as to realize the chamfering of the product 6 to be chamfered, which can realize the automatic chamfering of the product 6 to be chamfered, and improve the overall production efficiency of the product.

[0027] The product 6 to be chamfered is an injection molded part. The base 1 can be a workbench, and the upper surface of the base 1 is horizontal. The support part 21 can be plate-shaped and horizontally arranged; specifically, the support part 21 is a rectangular plate. The chamfering blade 41 is existing technology and is not limited here. The model of the chamfering blade 41 can be selected according to the size of the product 6 to be chamfered. When the chamfering blade 41 moves linearly along the first horizontal direction and rotates along the axis extending along the first horizontal direction, the chamfering blade 41 can contact the burrs on the product to be chamfered to achieve chamfering of the product.

[0028] Please see Figure 1 The base 1 has three enclosure plates 11 connected end to end in sequence. The three enclosure plates 11 form a working space 15. The pushing mechanism 2, the fixing structure 3 and the chamfering mechanism 4 are all located in the working space 15. When the chamfering blade 41 chamfers the product 6 to be chamfered, the three enclosure plates 11 can block the debris of the product 6 to be chamfered.

[0029] The base 1 also has an initial feeding position that is spaced apart from the chamfering working position; the pushing mechanism 2 further includes a first linear drive device 22, which includes a first fixed part 221 and a first movable part 222 that move relatively linearly. The first fixed part 221 is disposed on the base 1, and the first movable part 222 is disposed on the support part 21, for driving the support part 21 to switch between the chamfering working position and the initial feeding position.

[0030] By controlling the movement of the first movable part 222, when the support part 21 is switched to the initial feeding position, the product 6 to be chamfered can be easily fixedly installed on the support part 21. By controlling the first movable part 222, when the support part 21 is switched to the chamfering working position, the product to be chamfered can be chamfered.

[0031] Please see Figure 2 and Figure 3 The first linear drive device 22 can be a first electric actuator, the first fixed part 221 can be a mounting part of the first electric actuator, and the first movable part 222 can be a telescopic rod of the first electric actuator. In the embodiments described in this application, the first linear drive device 22 is a first linear cylinder, the first fixed part 221 is the cylinder seat of the first linear cylinder, and the first movable part 222 is the telescopic rod of the first linear cylinder.

[0032] The cylinder seat of the first linear cylinder is fixedly connected to a first mounting base 12. The first mounting base 12 is mounted on the base 1, and two first cylinder buffers 13 are fixedly mounted on the first mounting base 12. By setting two first cylinder buffers 13, the first linear cylinder can be protected.

[0033] The first movable part 222 moves along a second horizontal direction, which is perpendicular to the first horizontal direction.

[0034] To guide the sliding of the support part 21, two first slide rails 14 are fixedly installed on the base 1. Both first slide rails 14 are fixedly connected to the first mounting seat 12. The extension direction of the two first slide rails 14 is parallel to the movement direction of the first movable part 222. The bottom side of the support body 213 is provided with a first slide block 211 corresponding to the two first slide rails 14. The corresponding first slide block 211 is slidably installed on the corresponding first slide rail 14, which improves the stability of the sliding installation of the support part 21.

[0035] The supporting part 21 includes a supporting body 213 and a clamping part 212 detachably connected to the supporting body 213. A limiting recess 2121 is provided on the clamping part 212 to support the product 6 to be chamfered. By placing the product 6 to be chamfered on the clamping part 212, with at least a portion of the product 6 placed within the limiting recess 2121, the product 6 to be chamfered can be positioned horizontally. In this application, the clamping part 212 is plate-shaped and can be detachably and fixedly mounted to the supporting part 21 by bolts.

[0036] To secure the product 6 to be chamfered, the clamping part 212 can be engaged with the product 6 by a snap-fit ​​method, such as the limiting recess 2121 engaging with the product 6. The shape and size of the limiting recess 2121 are designed according to the structure of the product 6 to be chamfered.

[0037] Multiple clamping parts 212 are provided, and clamping parts 212 of different specifications are used to support products 6 of different specifications to be chamfered, so that the same support body 213 can be combined and installed with clamping parts 212 of different specifications. When it is necessary to chamfer a different model of product 6 to be chamfered, the corresponding clamping part 212 can be installed on the support part 21, so that the corresponding product 6 to be chamfered can be installed on the upper side of the support part 21.

[0038] Please see Figure 3 In order to hold the product 6 to be chamfered from the top, the fixing structure 3 includes a holding part 31, which is movably disposed at the upper end of the supporting part 21 in the vertical direction. Along the movement path of the holding part 31, the holding part 31 can press against the upper end of the product 6 to be chamfered. During the descent of the holding part 31, the lower side of the holding part 31 can press against the product 6 to be chamfered, thereby achieving vertical holding and fixing of the product 6 to be chamfered.

[0039] Through the cooperation of the clamping part 212 and the pressing part 31, the product 6 to be chamfered can be clamped and fixed in the horizontal and vertical directions, thereby improving the stability of the product 6 to be chamfered.

[0040] The pressing part 31 can be configured according to the shape of the product 6 to be chamfered, so as to increase the contact area between the pressing part 31 and the product 6 to be chamfered and reduce the pressure on the product 6 to be chamfered; specifically, the pressing part 31 is in the shape of a rectangular plate, and the material of the pressing part 31 is not specifically limited.

[0041] The holding part 31 also has a rotational travel along an axis extending in the vertical direction to avoid misaligning with the product 6 to be chamfered. After the holding part 31 moves upward to release the pressure between the holding part 31 and the product 6 to be chamfered, when the chamfered product is taken out upward, by controlling the rotation of the holding part 31, the holding part 31 can be misaligned with the chamfered product in the vertical direction, which facilitates the removal of the chamfered product and also facilitates the installation of the product 6 to be chamfered on the support part 21. Finally, while controlling the rotation of the holding part 31, it moves downward, and the holding part 31 can press against the product 6 to be chamfered.

[0042] Please see Figure 3 The fixing structure 3 further includes a rotary cylinder 32, the cylinder seat of which is connected to the support portion 21, and the telescopic rod of which is connected to the pressing portion 31. By controlling the rotary cylinder 32, the pressing portion 31 can be rotated along its vertical axis while simultaneously moving up and down.

[0043] A working space 15 is formed on the base 1, and the pushing mechanism 2 is disposed within the working space 15. A feeding port 16 is formed on one side of the working space 15 for feeding the product 6 to be chamfered onto the support part 21. A safety light curtain 5 is provided at the feeding port 16. The safety light curtain 5 can form a protective barrier through an infrared beam and monitor the feeding port 16 in real time. When the beam is blocked, it triggers an emergency stop of the equipment, thereby ensuring personnel safety.

[0044] The feeding port 16 is located in the moving direction of the support part 21. Specifically, the initial feeding position is set close to the feeding port 16. After the support part 21 is switched to the initial feeding position, the product 6 to be chamfered can be easily installed on the support part 21 through the feeding port 16.

[0045] To reduce the amount of product debris flying out of the feed port 16, a door panel can be installed at the feed port 16.

[0046] Please see Figure 2 and Figure 3 The chamfering mechanism 4 further includes a mounting plate 42, which is linearly and movably mounted on the base 1 along a first horizontal direction; the chamfering blade 41 is rotatably mounted on the mounting plate 42 along an axis extending along the first horizontal direction.

[0047] When the mounting plate 42 moves along the first horizontal direction, the chamfering blade 41 can move along the first horizontal direction; at the same time, the chamfering blade 41 rotates along the axis of the first horizontal direction, so that while the chamfering blade 41 moves along the first horizontal direction, the chamfering blade 41 rotates to remove the chamfered side of the product 6 to be chamfered.

[0048] The chamfering mechanism 4 includes a second linear drive device 43, which comprises a second fixed part 431 and a second movable part 432 that are relatively movable along a first horizontal direction. The second fixed part 431 is disposed on the base 1, and the second movable part 432 is disposed on the mounting plate 42. When the second movable part 432 moves, it can drive the mounting plate 42 to move, thereby realizing the movement of the chamfering blade 41 along the first horizontal direction.

[0049] The second linear drive device 43 can be a second electric actuator, the second fixed part 431 is the mounting part of the second electric actuator, and the second movable part 432 is the telescopic rod of the second electric actuator. In the embodiment described in this application, the second linear drive device 43 is a second linear cylinder, the second fixed part 431 is the cylinder body of the second linear cylinder, and the second movable part 432 is the telescopic rod of the second linear cylinder.

[0050] The cylinder seat of the second linear cylinder is fixedly connected to a second mounting base 17. The second mounting base 17 is mounted on the base 1, and two second cylinder buffers 18 are fixedly mounted on the second mounting base 17. By setting two second cylinder buffers 18, the second linear cylinder can be protected.

[0051] To guide the sliding of the mounting plate 42, two second slide rails 19 are provided on the base 1. Both second slide rails 19 extend along the first horizontal direction and are fixedly connected to the second mounting base 17. Second slide blocks 421 are provided on the bottom side of the mounting plate 42 corresponding to the two slide rails. The corresponding second slide blocks 421 are slidably mounted on the corresponding second slide rail 19. The cooperation between the second slide blocks 421 and the second slide rails 19 improves the sliding stability of the mounting plate 42.

[0052] Please see Figure 1 and Figure 3 A limiting block 191 is fixedly installed at one end of the second slide rail 19 near the support portion 21. When the mounting plate 42 slides and moves close to the support portion 21, the second slide block 421 can abut against the corresponding limiting block 191, thereby limiting the sliding of the mounting plate 42 and reducing the slippage of the mounting plate 42 from the second slide rail 19.

[0053] The chamfering mechanism 4 further includes a rotation drive unit 44, which includes a drive motor. The motor mount of the drive motor is disposed on the mounting plate 42, and the motor spindle of the drive motor is driven and connected to the chamfering cutter 41. When the drive motor rotates, it enables the chamfering cutter 41 to rotate synchronously.

[0054] Specifically, the drive motor is a servo motor, and the chamfering blade 41 is coaxially mounted on the output shaft of the drive motor. The rotation drive unit 44 can also be other structural components in the prior art that can control the rotation of the chamfering blade 41 through a drive connection, and is not limited here.

[0055] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
