New description: [New technical field] The present invention relates to a mold, in particular to an injection mold. [Prior Art] Referring to the sixth figure, the conventional mold 20 includes a mold 21 and a movable mold 22 corresponding to the fixed mold 21; the fixed mold 21 is fixed with a skew guide 23; the movable mold 22 is slidably mounted. A slider 24 is disposed, and the slider 24 is provided with a guide post hole (not shown) that cooperates with the inclined guide post 23. Referring to the seventh figure, when the mold 20 is opened, that is, when the product is demolded, the fixed mold 21 is moved together with the inclined guide column 23, and under the action of the inclined guide column 23, the slider 24 slides and separates from the product, and the product remains in the product. On the moving mold 22. However, when the mold 20 is opened, that is, when the product is demolded, the portion of the slider 24 that is in contact with the product is separated from the product at the same time, so that the adhesive force of the product and the slider 24 is often large, and accordingly, the product needs to withstand The pulling force brought by the slider 24 is also large, causing the product to be deformed by the slider 24 and failing to meet the production requirements. [New content] This creation provides an injection mold for preventing deformation of a product during demolding in response to the above-mentioned deficiencies of the prior art. In order to achieve the above purpose, the injection mold provided by the present invention comprises a certain mold, a skew guide pillar, a stopper, a movable mold, a slider and a pushing mechanism; the inclined guide column is fixedly mounted on the fixed mold; The block is fixedly mounted on the fixed mold, and has a stop surface on the block; the movable mold is corresponding to the fixed mold; the slider is slidably mounted on the movable mold, the slider has a forming portion, the sliding a guide post hole and a push rod hole extending to the end surface of the forming portion are formed on the block; the forming portion can form a cavity with the fixed mold and the movable mold; and the pushing mechanism is mounted on the slider, The ejector 3 mechanism includes an ejector rod slidably mounted in the ejector rod hole of the slider and a spring mounted on the ejector rod and the slider to prevent the ejector rod from extending into the cavity Wherein, the ejector pin can be held against the movable mold by the stopper surface at the initial stage of the mold opening. As described above, the injection mold of the present invention holds the product by a pusher when the cover is demolded, which not only reduces the contact surface between the product and the slider, but also reduces the adhesion between the product and the slider, and the product The separation process from the slider is also changed from "the process of simultaneous separation of various parts" to the process of "gradual separation from small to large from the middle"" to prevent the product from being deformed by the slider, thereby ensuring the molding quality of the product. [Embodiment] In order to explain in detail the technical contents, structural features, objects and effects of the present invention, the embodiments are described in detail below with reference to the drawings. Referring to the first, second and third figures, the injection mold 10 of the present invention comprises a certain mold 11, a inclined guide column 13, a stopper 14, a movable mold 12, a slider 15 and an ejector mechanism 16. The fixed mold 11 is disposed corresponding to the movable mold 丨 2; the inclined guide post 13 and the stopper 14 are fixedly mounted on the fixed mold u, and the stopper 14 has a shift surface 141 thereon. The slider 15 is slidably mounted on the movable mold 12. The slider 15 has a molding portion 151. The slider 15 defines a guide post hole (not shown) and an extension that cooperates with the oblique guide 13 pillar. The ejector pin hole 152 to the end surface of the molding portion 151; the molding portion 151 can surround the molding die 11 and the movable mold 12 to form a cavity. The ejector mechanism 16 is mounted on the slider 15. The ejector mechanism 16 includes an ejector rod 161 slidably mounted in the ejector rod hole 152 of the slider 15 and a spring 162. The push rod 161 and the slider 15 are arranged to prevent the ejector rod (6) from extending into the cavity; wherein the ejector rod 161 can be held against the movable mold 12 by the stop surface 141 during the initial stage of the mold opening. A limit groove ι611 is defined on the push top #161, and a limit pin 153 is fixed on the slider 15, and the limit pin 153 protrudes into the limit groove 611 to prevent the push rod 161 from slipping out or falling off. The ejector pin 161 includes a ejector head 1612 and a ejector tail 1613. The ejector head 1612 is sized larger than the ejector tail 1613. The push cup hole 152 includes a tail cavity 1521 extending to the end surface of the forming portion 51 and matching the size of the ejector tail 1613, a spring cavity 1522 communicating with the tail cavity 1521 and matching the size of the spring 162, and a spring cavity 1522 The spring cavity 1522 is connected and/or the externally communicated with the head cavity 1523 of the size of the ejector head 1612; the ejector tail 1613 is placed in the tail cavity 1521, the spring 162 is placed in the spring cavity 1522, and the ejector head 1612 is placed In the head cavity 1523. When the mold is closed, the parts of the injection mold 1 are matched, the top end of the push rod 丨6丨 is in contact with the stop surface 141, the end is flush with the end surface of the forming portion Mi, and the spring μ is slightly compressed to prevent the ejector rod 161 from sliding. Into the cavity. When the mold is opened, the fixed mold 11 is moved upward together with the inclined guide post 13 and the stopper 14, and the slider 15 slides to the right under the action of the inclined guide post 13. Referring to the fourth figure, in the first half of the mold opening, the top end of the ejector rod 161 abuts against the stop surface 141 of the stopper 14, the end protrudes from the end surface of the molding portion 151 and abuts against the product, and the slider 15 slides to the right and the product. Slowly separating, at this time the spring 162 is gradually compressed. Referring to the fifth figure, the second half of the mold is opened, the block 14 continues to move upward, the slider 15 continues to slide to the right, and the push rod 161 is disengaged from the stop surface 141 of the block 14 and is slowly bounced by the magazine 162. Finally, The limit pin 153 limits the ejection distance of the ejector pin 161, the spring 162 returns to the initial state, and the product is released. As described above, the present injection mold 1 is held against the product by the ejector rod 161 during demolding. This not only reduces the contact surface of the product with the slider 15 but also reduces the adhesion of the M396751 product to the slider 15. Moreover, the process of separating the product from the slider 15 is also separated from the simultaneous separation of the various parts, and becomes a process of "gradual separation from small to large from the middle", thereby preventing the product from being deformed by the slider 15, thereby ensuring the molding of the product.
