Description

Technical Field

[0001] The invention relates to the technical field of injection molding demoulding mechanisms, and in particular to a demoulding mechanism for an injection mold of a buckle mounting seat. Background Art

[0002] The clip mount injection mold refers to the mold used to manufacture the clip mount during the injection molding process. This mold is usually used to produce various plastic parts, such as automotive parts, home appliance parts, etc., and plays a very important role in production. During the injection molding of the clip mount, a demoulding mechanism is required to demould the completed clip mount.

[0003] The current demoulding mechanism of the injection mold of the clip mounting seat usually pushes the clip mounting seat out of the mold at one time through a push rod. Since the clip mounting seat that has just been injection molded is tightly connected to the injection mold, this demoulding method will cause the push rod to rigidly push the clip mounting seat, which may easily cause scratches or damage to the clip mounting seat, reducing the demoulding effect. Therefore, it is urgent to design a demoulding mechanism for the injection mold of the clip mounting seat. Summary of the invention

An arc-shaped inclined groove 8 and a straight groove 9 are opened on the surface of the round roller 7. The arc-shaped inclined groove 8 and the straight groove 9 are connected end to end, and the arc-shaped inclined groove 8 and the straight groove 9 are connected. A sliding column 20 is slidably installed inside the arc-shaped inclined groove 8 and the straight groove 9. The end of the sliding column 20 away from the round roller 7 is fixedly installed on the side of the top plate 5. A ratchet 11 is fixedly sleeved on the surface of the first rotating shaft 10, and a ratchet pawl 12 is rotatably installed on the bottom of the mold 1 through a torsion shaft, and the end of the ratchet pawl 12 is located adjacent to the ratchet 11. Between the ratchet teeth, a second pulley 19 is fixedly sleeved on the surface of the first rotating shaft 10, a second rotating shaft 14 is rotatably installed at the bottom of the mold 1, a first pulley 18 is fixedly installed on the top of the second rotating shaft 14, a belt 17 is sleeved on the surfaces of the first pulley 18 and the second pulley 19, a first bevel gear 25 is fixedly sleeved on the surface of the corresponding shaft 16, the first bevel gear 25 is a missing gear, a second bevel gear 26 is meshed on the side of the first bevel gear 25, a sleeve 21 is vertically fixedly installed on the bottom of the second bevel gear 26, the surface of the sleeve 21 is rotatably installed inside the top plate 5, a sleeve rod 22 is vertically slidably installed on the end of the sleeve 21 through a spline, and the end of the sleeve rod 22 is fixedly installed at the top center of the first pulley 18.

[0037] The working principle of the present invention is as follows: when the injection-molded buckle mounting seat needs to be ejected and demolded, it is only necessary to start the dual-axis motor 15 to drive the two shafts 16 to rotate, the rotation of the two shafts 16 drives the two first bevel gears 25 (missing gears) and the two eccentric wheels 23 to rotate, the rotation of the eccentric wheels 23 drives the rotating plate 24 to rotate, the rotation of the rotating plate 24 drives the cross plate 3 to reciprocate in the vertical direction, the reciprocating movement of the cross plate 3 drives the ejector rod 2 to reciprocate, so as to facilitate multiple reciprocating ejection of the buckle mounting seat;

[0038] The first bevel gear 25 rotates intermittently to drive the second bevel gear 26 to rotate, the second bevel gear 26 rotates to drive the sleeve 21 to rotate, the sleeve 21 rotates to drive the sleeve rod 22 to rotate, the sleeve rod 22 rotates to drive the first pulley 18 to rotate, the first pulley 18 rotates to drive the belt 17 to rotate, the belt 17 rotates to drive the second pulley 19 to rotate, the second pulley 19 rotates to drive the first shaft 10 to rotate, the first shaft 10 rotates to drive the roller 7 and the ratchet 11 to rotate, due to the action of the ratchet 12, the first shaft 10 and the roller 7 rotate. The roller 7 will only rotate in the reverse direction and will not rotate forward, so that the round roller 7 will not rotate when rotating, thereby improving the stability of the round roller 7. The rotation of the round roller 7 drives the arc-shaped inclined groove 8 and the straight groove 9 to rotate. Since the slide column 20 is located inside the arc-shaped inclined groove 8 and the straight groove 9, the slide column 20 will move upward. The upward movement of the slide column 20 drives the top plate 5 to move upward and causes the spring rod 6 to generate tension, further realizing that the top rod 2 moves up and down once and then moves upward as a whole for a distance, and the buckle mounting seat can be ejected and demolded by reciprocating in sequence;

[0039] When the slide post 20 moves to the top end of the arc-shaped bevel groove 8 (located at the connection between the top end of the arc-shaped bevel groove 8 and the straight groove 9), the demoulding of the buckle mounting seat is completed. The tension generated by the spring rod 6 will cause the top plate 5 to move downward. The downward movement of the top plate 5 drives the slide post 20 to move downward along the straight groove 9, so that the slide post 20 is re-located at the connection between the end of the arc-shaped bevel groove 8 and the straight groove 9. In summary, the demoulding of the buckle mounting seat can be completed.

[0040] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
