[0002] In the field of injection mold technology, when the product's sliding surfaces have deep cavities or many ribs, it is easy for the sliding surfaces to stick. In this case, ejector pins are needed to eject the product. Currently, the traditional reset structure of the ejector plate is still commonly used, which involves placing a reset rod on the front of the product's sliding surface. However, while this reset structure can be applied to some products, it is not suitable for some products due to their own structural reasons. For example, if the product's sliding surface does not have through holes, there is no space to set up a reset rod structure on the front of the ejector plate for resetting the ejector plate, making it difficult for the ejector plate to reset and easily affecting the injection molding efficiency.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This utility model embodiment provides a reset structure for a mold slide ejector plate, such as... Figures 1 to 5 As shown, the reset structure of the mold slide ejector plate includes a first slide 1 and a second slide 2 located below the first slide 1. The first slide 1 is slidably mounted on the second slide 2. The first slide 1 is equipped with an inclined guide post 3 for driving it to slide in the horizontal direction. The bottom end of the first slide 1 is provided with a first limiting block 11. A second limiting block 21 is movably inserted into the second slide 2. The second limiting block 21 is limited and engaged with the first limiting block 11 and can move in and out of the second slide 2. A support member 4 is also connected between the first slide 1 and the second slide 2. The first end of the support member 4 is fixed on the second slide 2. The second end of the support member 4 extends in the horizontal direction and passes through the first slide 1. The second end of the support member 4 is also connected to an ejector plate 5 located in the first slide 1. The ejector plate 5 is provided with a plurality of horizontally distributed ejector pins 6.

[0027] Specifically, in this embodiment, the upper surface of the second row position 2 is provided with a sliding groove 201. The horizontal length of the sliding groove 201 is greater than that of the first row position 1 to provide space for the first row position 1 to slide. The inner bottom surface of the sliding groove 201 is provided with a hollowed-out through groove 202, that is, the bottom end of the through groove 202 penetrates the bottom surface of the second row position 2. The first row position 1 is placed in the sliding groove 201 and the first limiting block 11 is inserted into the through groove 202. The first limiting block 11 moves within the through groove 202 as the first row position 1 moves to limit the sliding distance of the first row position 1. Figure 3 As shown, the inclined guide post 3 is inserted obliquely into the first row position 1 from the upper end. Correspondingly, the first row position 1 is provided with a hole for the inclined guide post 3 to be inserted. The second limiting block 21 is movably inserted into the through groove 202 to move in and out of the through groove 202.

[0028] For example, when the first sliding position 1 slides, its first limiting block 11 gradually abuts against the second limiting block 21. When the first limiting block 11 gradually comes into contact with the second limiting block 21, the second limiting block 21 is pushed out of the through groove 202. The second sliding position 2 is not limited, and as the first sliding position 1 continues to slide, it can drive the second sliding position 2 to move together. As a result, the support member 4 on the second sliding position 2 moves accordingly. Finally, when the first sliding position 1 and the second sliding position 2 disengage from the product's undercut surface, the ejector plate 5 also retracts and resets.

[0029] The first limiting block 11 has a first inclined surface at its bottom end, facing downwards. The second limiting block 21 has a protrusion 211 at its top end, and a second inclined surface on the protrusion 211 that corresponds to and fits against the first inclined surface, facing upwards. Through the cooperation of the first and second inclined surfaces, the second limiting block 21 is pushed out of the through groove 202 by the first limiting block 11 at a suitable sliding distance. The top end of the second limiting block 21 also has a clearance groove 212 on one side of the protrusion 211 to facilitate the movement of the first limiting block 11. The inclined surface of this clearance groove 212 also corresponds to the first inclined surface, and the inclined surface of the clearance groove 212 and the second inclined surface are located on the same inclined surface.

[0030] To enable the second limiting block 21 to move into the through slot 202 for reset without abutting the first limiting block 11, in this embodiment, a locking screw 71 is provided at the center of the bottom end of the second limiting block 21, and a spring 72 is provided on both sides of the locking screw 71 at the bottom end of the second limiting block 21 to provide elastic reset force to the second limiting block 21. It is understood that in practical applications, the second sliding position 2 should also slide horizontally within the mold, while the bottom end of the locking screw 71 is fixed at a suitable position within the mold, and the two springs 72 are elastically limited below the second sliding position 2, thereby providing elastic reset force to the second limiting block 21. When the mold is closed, the first limiting block 11 does not act on the second limiting block 21. The second limiting block 21 moves into the through groove 202 under the action of the spring 72 to position the second slide 2. When the mold is opened, the first slide 1 moves backward first, the first limiting block 11 acts on the second limiting block 21, and then gradually moves the second limiting block 21 out of the through groove 202, thereby releasing the positioning of the second slide 2. Finally, the first slide 1 can drive the second slide 2 to move backward together.

[0031] Specifically, in this embodiment, the upper end of the second row position 2 has a first step 21 formed on one side of the slide groove 201, and the first end of the support member 4 is fixed on the first step 21. The support member 4 consists of a support block 41 and a support rod 42. The support block 41 is fixed on the first step 21, and the support rod 42 is connected to the support block 41 by fasteners, such as screws, allowing for a detachable connection between the support rod 42 and the support block 41. The support rod 42 is perpendicular to the support block 41 and parallel to the second row position 2. The end of the support rod 42 away from the support block 41 passes into the first row position 1 and connects to the ejector plate 5. The first row position 1 can slide horizontally along the support rod 42 on the second row position 2. The connection between the support block 41 and the support rod 42 is L-shaped.

[0032] Furthermore, a second step 22 is formed at the upper end of the second row position 2 on the other side of the slide groove 201. The second step 22 is lower than the first step 21, and the slide groove 201 is formed between the first step 21 and the second step 22. The first step 21 and the second step 22 can limit the movement of the first row position 1. The second step 22 is provided with a U-shaped limiting groove 220, and the lower part of the first row position 1 near the second step 22 is provided with a limiting part 101 adapted to the U-shaped limiting groove 220. For example, as... Figure 3 As shown, the first sliding position 1 slides to the left, and its left side abuts against the right side of the first step 21. The first sliding position 1 slides to the right, and the limiting part 101 is adapted to the U-shaped limiting groove 220, which can limit the sliding position of the first sliding position 1 in the left and right directions. It should be noted that the specific stroke of the first sliding position 1 and the second sliding position 2 can be designed and selected according to the actual application needs, and is not specifically limited in this embodiment.

[0033] Specifically, in this embodiment, the first row position 1 has a receiving cavity 102, the ejector plate 5 is placed in the receiving cavity 102, and the end of the support rod 42 away from the support block 41 is located in the receiving cavity 102 and connected to the ejector plate 5; when the first row position 1 slides horizontally relative to the second row position 2, the relative position of the ejector plate 5 in the receiving cavity 102 changes. The ejector plate 5 includes an overlapping ejector base plate 51 and an ejector panel 52, with the ejector panel 52 located on the side of the ejector base plate 51 away from the support rod 42; the ejector base plate 51 is connected to the support rod 42, and multiple ejector pins 6 are disposed on the ejector panel 52. When the first row position 1 slides first, the ejector plate 5 does not move temporarily, but its relative position in the receiving cavity 102 changes due to the sliding of the first row position 1. As the first row position 1 drives the second row position 2 to move, the ejector plate 5 also moves with the second row position 2, thereby resetting the ejector plate 5.

[0034] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
