It should be understood that in the embodiment of the present utility model, the demolding mechanism 100 may be an integral part of the injection mold, or may be an independent entity other than the injection mold, which is not limited in this embodiment. In this embodiment, the third stripper plate 130 may be a part of the mold cavity, and the demolding may be performed by pulling the third stripper plate 130 away from the injection product 200. Referring to fig. 1-2, the demolding mechanism 100 may include a first demolding plate 110, a second demolding plate 120, and a third demolding plate 130 sequentially connected from right to left, the third demolding plate 130 may be connected with the injection product 200, the insert 140 may sequentially penetrate through the inner cavities of the third demolding plate 130, the second demolding plate 120, and the first demolding plate 110, the insert 140 may be fixed to the inner cavity of the first demolding plate 110, and may move with the movement of the first demolding plate 110. Specifically, an end of the first stripper plate 110 facing away from the injection product 200 may be coupled to a drive assembly 150, and the drive assembly 150 may drive the first stripper plate 110 to move in a direction opposite to the injection product 200, and the insert 140 secured to the first stripper plate 110 may then move along the third stripper plate 130 and the interior cavity of the second stripper plate 120, thereby disengaging the insert 140 from the injection product 200. It should be noted that, in the embodiment of the present utility model, the driving assembly 150 may be a motor, a cylinder, or other driving devices, which may be selected by those skilled in the art according to practical situations, and the embodiment is not limited thereto.
Further, in order to keep the third mold plate coupled to the injection molding product 200 while the insert 140 is being pulled away from the injection molding product 200 by the first mold plate 110, the embodiment of the present utility model may provide a stopper 121 on the bottom surface of the second mold plate 120, and the stopper 121 may be fixed at this time.

In addition, the third stripper plate 130 may have a connection member 131 extending toward the first stripper plate 110 at a bottom surface thereof, one end of the connection member 131 may be connected to the bottom surface of the third stripper plate 130, the other end of the connection member 131 may be connected to the bottom surface of the first stripper plate 110, the connection member 131 may be disposed through the stopper 121, and one end of the connection member 131 adjacent to the third stripper plate 130 may be provided with a protrusion 1311. It will be appreciated that in this embodiment, the connecting member 131 may move with the movement of the first stripper plate 110 until the protrusion 1311 on the connecting member 131 abuts the stop 121, i.e., the length of the connecting member 131 may determine the distance the first stripper plate 110 pulls the insert 140 away. When the boss 1311 on the connector 131 abuts the stop 121, indicating that the insert 140 has now been completely disengaged from the injection product 200, the third stripper plate 130 may be withdrawn from the injection product 200. Based on this, after the protrusion 1311 abuts against the stopper 121, the first stripper plate 110 may pull the second stripper plate 120 and the third stripper plate 130 to move together by abutment of the protrusion 1311 against the stopper 121, thereby disengaging the third stripper plate 130 from the injection product 200, thereby achieving the sectional demolding.
In the embodiment of the present utility model, the driving assembly 150 drives the first stripper plate 110 to withdraw the insert 140 from the injection product 200, and in this process, the stopper 121 is fixed so that the second stripper plate 120 and the third stripper plate 130 do not move along with the movement of the first stripper plate 110, and after the first stripper plate 110 withdraws the insert 140 from the injection product 200, the protrusion 1311 abuts against the stopper 121, so that the second stripper plate 120 and the third stripper plate 130 start to move along with the movement of the first stripper plate 110, thereby separating from the injection product 200. The embodiment realizes sectional demolding, reduces the possibility that the insert 140 pulls the injection molding product 200 apart in the demolding process due to the adhesion of the insert 140 and the injection molding product 200, and improves the yield of injection molding, thereby greatly improving the reliability of injection molding.

Further, the opening 122 may be sized to block the boss 1311 from passing through the opening 122, thereby enabling abutment of the stopper 121 with the connector 131. It can be appreciated that when the stopper 121 abuts against the connecting member 131, the connecting member 131 generates a larger transverse tangential force on the stopper 121, and therefore, in the embodiment of the present utility model, the first groove 1211 and the side of the second stripper plate 120 close to the protrusion 1311 can be connected through the inclined surface 123 in a transitional manner, and the protrusion 1311 can abut against the inclined surface 123, so that the transverse tangential force on the stopper 121 is converted into a relatively smaller transverse tangential force and a relatively smaller radial force, the possibility that the stopper 121 is cut off by the tangential force of the connecting member 131 is greatly reduced, and the service life of the stopper 121 is prolonged. Further, in the present embodiment, a side of the boss 1311 facing the stopper 121 may also be provided as the inclined surface 123.
