Description

Technical Field

[0001] This application relates to the field of grinding equipment technology, specifically a gate grinding mechanism. Background Technology

[0002] Injection molded parts are products manufactured through the injection molding process. The gate of an injection molded part is the entrance and channel through which the molten plastic enters the mold cavity during the injection process.

[0028] like Figure 1-3 As shown, this application provides a gate grinding mechanism, including:

[0029] The grinding assembly includes a worktable 11;

[0030] The movable components include a support rod 21, a pedal 22, a fixed rod 23, a fixed shaft 24, a movable column 25, a slot 26, a fixed block 27, a telescopic spring 28, and a movable block 29. The support rod 21 is fixedly connected to the inner side of the lower end of the worktable 11. The pedal 22 is rotatably connected to the center of the outer surface of the support rod 21. The fixed rod 23 is fixedly connected to both ends of the outer side of the upper end of the pedal 22. The fixed shaft 24 is slidably connected to the inner side of the outer end of the fixed rod 23. The movable column 25 is fixedly connected to the inner side of the fixed shaft 24. The slot 26 is fixedly connected to the top of the movable column 25. The fixed block 27 is fixedly connected to both sides of the upper end of the worktable 11. The telescopic spring 28 is fixedly connected to both sides of the upper end of the worktable 11. The movable block 29 is fixedly connected to the top of the telescopic spring 28.

[0031] The support rod 21 supports the pedal 22, the pedal 22 drives the fixed rod 23 to rotate, the rotation of the fixed rod 23 drives the fixed shaft 24 to move vertically, the movement of the fixed shaft 24 drives the movable column 25 to move vertically, the movable column 25 supports the slot 26, the fixed block 27 guides the movement of the movable block 29, the telescopic spring 28 resets the movable block 29, and the movable block 29 limits the two sides of the injection molded part.

[0032] The grinding assembly also includes a drive motor 12 and a grinding disc 13. The drive motor 12 is fixedly connected above the worktable 11, and the grinding disc 13 is fixedly connected to the output shaft of the drive motor 12 in the center.

[0033] The drive motor 12 is used to drive the grinding disc 13 to rotate, and the grinding disc 13 is used to grind the gate of the injection molded part.

[0034] The movable column 25 extends from the center of the upper end of the worktable 11 to both sides, and the slot 26 is located at the center of the upper end of the worktable 11.

[0035] The movable column 25 can move vertically up and down along the center of the worktable 11, and the movable column 25 can drive the slot 26 to move vertically up and down at the top of the worktable 11.

[0036] The telescopic spring 28 is located inside the fixed block 27, which is located at the center of both sides of the slot 26. The movable block 29 is slidably connected to the inside of the fixed block 27.

[0037] When the movable block 29 moves upward on the fixed block 27, the movable block 29 can drive the telescopic spring 28 to stretch and generate elastic force.

[0038] Working principle: When grinding the gate of an injection molded part is required, the injection molded part is placed inside the slot 26, and then the pedal 22 is rotated. The pedal 22 rotates along the support rod 21 and drives the fixed rod 23 to rotate. The rotation of the fixed rod 23 tilts and drives the fixed shaft 24 to slide upward, causing the movable column 25 to slide vertically upward. The vertical upward sliding of the movable column 25 drives the slot 26 and the injection molded part to slide vertically upward. When the injection molded part moves upward, the upper ends on both sides of the injection molded part drive the movable block 29 to move upward. The upward movement of the movable block 29 drives the extension spring 28 to stretch, so that the movable block 29 applies downward pressure to the upper ends on both sides of the injection molded part, thereby limiting the injection molded part inside the slot 26 and keeping it stationary. At the same time, when the movable block 29 moves to the limit position inside the fixed block 27, the movable block 29 limits the injection molded part and the slot 26 to prevent the injection molded part and the slot 26 from moving upward. At this time, the gate position of the injection molded part just contacts the bottom end of the grinding plate 13, and the gate position of the injection molded part can be ground.

[0039] Please see Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0040] The feeding assembly includes a support plate 31, a reciprocating motor 32, a lead screw 33, a slider 34, a torsion spring 35, a stop bar 36, and a slide rail 37. The support plate 31 is fixedly connected to both sides of the worktable 11, the reciprocating motor 32 is fixedly connected to the outer side of the support plate 31, the lead screw 33 is rotatably connected to the inner side of the support plate 31, the slider 34 is threadedly connected to both sides of the outer surface of the lead screw 33, the torsion spring 35 is fixedly connected to the inner upper end of the slider 34, the stop bar 36 is rotatably connected to the inner upper end of the slider 34, and the slide rail 37 is fixedly connected to both sides of the upper end of the worktable 11.

[0041] The support plate 31 is used to support the reciprocating motor 32, which drives the lead screw 33 to rotate. The lead screw 33 drives the slider 34 to move. The slider 34 drives the torsion spring 35 and the stop rod 36 to support the torsion spring 35 and the stop rod 36. The torsion spring 35 supports the stop rod 36 and the stop rod 36 drives the injection molded part at the upper end of the slide rail 37 to move.

[0042] One end of the slide rail 37 is connected to the outside of the slot 26, and the outer surfaces of the lead screw 33 are respectively provided with opposite thread structures, and the outer end of the lead screw 33 is fixedly connected to the output shaft of the reciprocating motor 32.

[0043] When the lead screw 33 rotates, the sliders 34 on both sides of the outer surface of the lead screw 33 can move towards each other or in opposite directions.

[0044] The bottom outer side of the stop lever 36 contacts the top of the slide rail 37, and the stop lever 36 is fixedly connected to the top of the torsion spring 35.

[0045] The stop lever 36 can only rotate counterclockwise at the upper end of the slider 34, causing the torsion spring 35 to deform. If the stop lever 36 rotates clockwise at the upper end of the slider 34, it will be blocked by the upper end of the slider 34.

[0046] Working principle: Since the injection molded part is placed inside the slot 26 directly below the grinding disc 13, the operator's fingers may still come into contact with the grinding disc 13. In this case, by placing the injection molded part at the outer end of one side slide rail 37 and then starting the reciprocating motor 32, the reciprocating motor 32 rotates, driving the lead screw 33 to rotate. The lead screw 33 drives the slider 34 to move towards the slot 26. At this point, the outer side of the stop bar 36 on one side contacts the outer side of the injection molded part, and the stop bar 36 is limited by the upper end of the slider 34 and cannot rotate. The stop bar 36 then drives the injection molded part to move along the slide rail 37 into the slot 26. At this point, the un-ground injection molded part pushes the ground injection molded part out of the slot 26 into the other side slide rail 37. The stop bar 36 on the other side rotates counterclockwise under the obstruction of the injection molded part until it is parallel to the slide rail 37. At the same time, the stop bar 36 continues to move towards the slot 26 under the drive of the slider 34. When the stop bar 36 is no longer in contact with the injection molded part, the stop bar 36 resets and is reset under the elastic force of the torsion spring 35. Then the reciprocating motor 32 is started to rotate in the opposite direction, so that the reciprocating motor 32 drives the slider 34 to rotate in the direction of the lead screw 33. At this time, the stop bar 36 on the outside of the ground injection molded part cannot rotate clockwise under the limit of the upper end of the slider 34. The stop bar 36 can then move the ground injection molded part from one side of the slide rail 37 to the other side under the drive of the slider 34, so that the operator is away from the grinding disc 13.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
