[0023] In the utility model, a plurality of springs 8 are arranged between the ejector plate 5 and the rear mold plate 6, so that when the ejector plate 5 moves toward the rear mold plate 9 to eject the product, it can be immediately reset by the spring 8, that is, the inclined ejector mechanism can also follow the ejector plate 5 to reset first; in addition, the slide is arranged on the front mold 1, so that when the mold is closed, the front mold slide mechanism follows the front mold 1 to reset when the mold is closed, so that the inclined ejector mechanism will not collide with the front mold slide mechanism, the mold can be smoothly reset, and the product manufacturing and molding is guaranteed.

[0024] In order to further improve the safety during mold closing, an induction switch 21 is arranged on the lower fixed plate 3. When the ejector plate 5 is reset, it will contact and trigger the induction switch 21; therefore, when the ejector plate 5 is completely reset, it will contact and trigger the induction switch 21, and then the injection molding machine receives the instruction and performs the mold closing work, so as to avoid the ejector and the inclined ejector mechanism from being broken during mold closing due to failure to reset.

[0025] Furthermore, a notch 31 is provided on one side of the lower fixing plate 3, and the sensing switch 21 is embedded and installed in the notch 31 by screws, thereby improving the compactness of the mold and protecting the sensing switch 21 to avoid damage to the sensing switch 21 due to accidental collision.

[0026] See also Figure 4As shown, a plurality of guide reset rods 41 are provided on the ejector plate 5, and a plurality of guide holes 42 are provided on the rear template 6. The guide reset rods 41 are movably inserted into the guide holes 42; the guide reset rods 41 are used to guide the ejector plate 5 to move, thereby improving the stability during operation.

[0027] Furthermore, a plurality of the springs 8 are correspondingly sleeved on the guide reset rod 41 .

[0028] Furthermore, a limiting circular hole 51 is coaxially arranged at the lower end of the guide hole 42 , and one end of the spring 8 is abutted against the limiting circular hole 51 .

[0029] See also Figure 3 , Figure 4 As shown, the front mold 1 includes an upper fixed plate 71 and a front mold plate 72, a front mold core 73 is arranged in the front mold plate 72, a guide column 74 is arranged on the upper fixed plate 71, the front mold plate 72 is movably arranged on the guide column 74, a countersunk hole 75 is arranged at the upper end of the upper fixed plate 71, and also includes a limiting bolt 76, the threaded end of the limiting bolt 76 passes through the countersunk hole 75 and is threadedly connected to the front mold plate 72, and the threaded head of the limiting bolt 76 can be movably arranged in the countersunk hole 75.

[0031] When the mold is opened, that is, the front mold 1 moves, the upper fixed plate 71 moves first, and the front mold plate 72 does not move at first. The upper fixed plate 71 drives the shovel base 82 to move, and the shovel base 82 cooperates with the sliding seat 81, thereby driving the sliding seat 81 to slide and demould. When the upper fixed plate 71 moves a certain distance, the countersunk hole 75 on the upper fixed plate 71 contacts the limit bolt 76, so that the upper fixed plate 71 drives the limit bolt 76 and the front mold plate 72 to move together to realize mold opening, and then the ejector plate 5 works to eject the product. After the product is ejected, the ejector plate 5 is immediately reset by the spring 8, that is, the inclined ejector mechanism can also follow the ejector plate 5 to reset first; when the mold is closed, the front mold sliding mechanism follows the front mold 1 to reset when the mold is closed. In this way, the inclined ejector mechanism will not collide with the front mold sliding mechanism, and the mold can be reset smoothly, ensuring the manufacturing and forming of the product.
