[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0026] The utility model provides a new injection mold with a slider and a slanted top structure, optimizes the mold structure design, changes the slanted top pin positioning to slanted top seat and limit block positioning, solves the defects of unstable pin positioning structure, inaccurate positioning, easy damage to the slanted top and pin, easy swing of the slanted top, and high processing precision requirements.

[0027] Figure 1-Figure 4 The figure shows the overall structure of an injection mold of a new type of slider with a slanted top structure according to the present invention. Figure 1-4 The main structure of this embodiment includes: a fixed mold assembly and a movable mold assembly.

[0028] The fixed mold assembly includes a panel 11, a nozzle plate 12, a fixed mold plate 13, an inclined guide column 14, a fixed mold insert 15, and a pressure block 16;

[0029] The movable mold assembly includes a slider 21, a tilted ejector 22, a tilted ejector seat 23, a limit block 24, a spring 25, a movable mold insert 26, a movable mold plate 27, a square iron 28, an ejector plate 29 and a bottom plate 210;

[0030] The pressure block 16 presses the inclined guide post 14 and is screwed to the fixed platen 13. The fixed mold insert 15 is also screwed to the fixed platen 13. The face plate 11, the nozzle plate 12, and the fixed platen 13 are also screwed together. The fixed mold assembly also includes a guide sleeve, which is embedded in the fixed platen 13. The fixed platen 13, the movable platen 27, the fixed mold insert 15, and the movable mold insert 26 are combined to form the mold cavity.

[0031] The T-slot at the root of the inclined ejector 22 is hung on the inclined ejector seat 23, the limit block 24 presses the spring 25, the inclined ejector seat 23 presses the limit block 24, the slider 21 presses the inclined ejector seat 23, the movable mold insert 26 is locked together with the movable mold plate 27 by screws, the movable mold plate 27, the square iron 28 and the bottom plate 210 are locked together by screws; the ejector plate 29 is locked together by screws.

[0032] During specific use, when the mold is opened, the driving force given by the inclined guide column 14 causes the spring 25 to be compressed, the limit block 24 moves downward, the slider 21 and the inclined ejector seat 23 move outward together, and the inclined ejector 22 moves upward in a T-shape to break away from the product inverted buckle, and the inclined ejector 22, the inclined ejector seat 23, and the slider 21 move outward again to the specified distance, so that the product can be smoothly ejected and the part can be taken out. When the mold is closed, the driving force given by the inclined guide column 14 causes the slider 21 and the inclined ejector seat 23 to move inward together, and the inclined ejector 22 is reset through the T-shape downward movement, and the slider 21 and the inclined ejector seat 23 continue to move inward to reset, the spring 25 is released from the compressed state, the limit block 24 is popped out and reset, so that the inclined ejector seat 23 is positioned and stops moving, thus completing a mold opening and closing cycle.

[0033] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
