[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4As shown, this utility model is a quick-release injection mold with an ejector guide mechanism, including a moving mold 9 and a fixed mold 11. The top of the moving mold 9 is connected to a movable seat 6, and the bottom of the fixed mold 11 is connected to a fixed seat 3. A bottom connecting plate 1 is fixed at the bottom of the fixed seat 3, and a groove is provided at the bottom of the movable seat 6 to allow the moving mold 9 to be inserted. In actual use, the movable seat 6 carrying the moving mold 9 moves downward, so that the moving mold 9 and the fixed mold 11 are combined to form an injection cavity. The injection material is injected into the injection cavity in advance. After cooling, the moving mold 9 is released, and left and right parts 10 are formed in the injection cavity. In order to realize the ejection of the left and right parts 10, ejector pins are provided on the surface of the fixed seat 3. The ejector pins can push the formed left and right parts 10 outward from the fixed mold 11 to realize the ejection.

[0025] A rectangular protrusion is fixed at the corner of the fixed seat 3, and a guide sleeve 4 is fixed on the surface of the rectangular protrusion. The telescopic column 5 is sleeved inside the guide sleeve 4. The telescopic column 5 moves radially under the constraint of the guide sleeve 4. A connecting hole 7 is opened on the surface of the movable seat 6 at the position corresponding to the telescopic column 5, so that the telescopic column 5 extends outward through the connecting hole 7 and abuts against the surface of the top cover 8. The movable seat 6 and the top cover 8 are connected by bolts, so that the telescopic column 5 and the top cover 8 are reinforced. Driven by the telescopic column 5, the movable seat 6 can reciprocate on the fixed seat 3.

[0026] The fixed base 3 has rectangularly distributed grooves on its surface edge. An internal block 13 is fitted into each groove. The surface of the internal block 13 has an inwardly inclined bevel, into which a guide rod 12 is inserted. A reinforcing threaded hole is provided on the side of the bevel. A mounting plate is fixed to the side of the guide rod 12. The mounting plate also has threaded holes. A screw can be used to confine the mounting plate within the bevel, causing the guide rod 12 to tilt towards the center of the fixed mold 11. After the moving mold 9 detaches from the fixed mold 11 and forms the left and right parts 10, the fixed base... The ejector pins on the surface of seat 3 push the left and right parts 10 away from the fixed mold 11. During this process, the left and right parts 10 are limited by the guide rod 12. An electric push rod is installed inside the guide rod 12. The output end of the push rod can move radially along the guide rod 12. When the ejector pin pushes away the left and right parts 10, the top of the electric push rod moves to the outer periphery of the ejection of the left and right parts 10, thereby limiting the ejection position of the left and right parts 10 to prevent the ejection deviation of the left and right parts 10 from causing collision damage and improving the finished product quality of the left and right parts 10.

[0027] The bottom of the moving mold 9 is fixed with a positioning insert 90. The positioning insert 90 fits tightly with specific parts of the left and right parts 10. During the injection molding stage, it can accurately limit the position of the left and right parts 10 in the mold and avoid poor molding due to position deviation. When the moving mold 9 starts to fix the mold 11, the positioning insert 90 and the left and right parts 10 can effectively drive the left and right parts 10 to move synchronously, which greatly enhances the stability of the left and right parts 10 as they follow the moving mold 9 out of the fixed mold 11.

[0028] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
