[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figures 1-4 As shown, a mold ejector plate structure includes a mounting base 1 and an ejector pin 4. The mounting base 1 is detachably mounted on the lower mold plate, and the mounting base 1 and the lower mold plate are installed by locking screws and bolts. The ejector pin 4 is mounted on the mounting base 1 and is used to abut against the upper mold plate. The ejector pin 4 connects with the upper mold plate and supports the side of the mold during use to prevent the product from deforming during mold opening, thus ensuring that the product will not be damaged due to deformation during the mold opening process. The ejector pin 4 includes a plug-in column 41 disposed above the mounting base 1 for retraction and reset. The top of the plug-in column 41 is rotatably connected to a rotating... The movable connecting column 42 is tapered, with a narrower top and wider bottom. During use, debris and slag will slide down the tapered surface, reducing the probability of debris and slag accumulation. The rotating connecting column 42 is rotatable. After mold opening, the operator only needs to rotate the rotating connecting column 42 to further clean the debris and slag on its surface. The top of the rotating connecting column 42 is fixed with a fixing pin 43 for abutting the upper mold plate. The fixing pin 43 is welded to the rotating connecting column 42 for abutting the upper mold plate.

[0025] A shielding side plate 44 is fixed to the periphery of the bottom of the rotating connecting column 42. The shielding side plate 44 is welded to the periphery of the bottom of the rotating connecting column 42 to shield debris and slag, so as to prevent debris and slag from falling everywhere and affecting other uses of the mold. A circular receiving groove 46 is provided between the shielding side plate 44 and the rotating connecting column 42 for collecting waste residue. The debris and slag that slide off the surface of the rotating connecting column 42 are collected.

[0026] The surface of the shielding side plate 44 is provided with a slag discharge notch 48, which is integrally formed with the shielding side plate 44, and is used to throw out the debris and slag when the rotating connecting column 42 rotates. The debris and slag thrown out by rotation will have a larger range of discard than directly falling due to inertia. The slag discharge notch 48 penetrates the side wall of the shielding side plate 44 longitudinally relative to the inserted vertical column 41, and is used to throw out the debris and slag.

[0027] The inside of the slag discharge notch 48 is provided with a guide inclined plate 47, which is integrally formed with the shielding side plate 44. The guide inclined plate 47 is designed as an inclined surface. The inclined surface design of the slag discharge notch 48 can throw out the debris and slag in a specified direction.

[0028] The effect achieved by the whole embodiment one is that the debris and slag will slide down along the conical surface during use, so as to reduce the probability of debris and slag accumulation. The rotating connecting column 42 is rotatably connected. After the mold is opened, the operator only needs to rotate the rotating connecting column 42. At this time, the debris and slag on the surface of the rotating connecting column 42 will be further cleaned. At the same time, the debris and slag are thrown out when the rotating connecting column 42 rotates. The debris and slag thrown out by rotation will have a larger range of discard than directly falling due to inertia. The inclined surface design of the slag discharge notch 48 can throw out the debris and slag in a specified direction.

The diameter of the two-section slot 32 is larger than that of the inserted vertical column 41. As shown in Figure 3 , the one-section slot 31 and the two-section slot 32 are designed as "convex" to facilitate the longitudinal resetting of the inserted vertical column 41 in the insertion slot 3 relative to the support base 2.
