[0024] Embodiment:

[0025] As shown in the attached Figure 1 to the attached Figure 5 figures:

[0026] The present utility model provides an injection mold with a tapered groove structure, including Base One 1 and Static Mold Base 8. A Moving Mold Base 2 is installed on one side of Base One 1, and a pair of demolding components are symmetrically installed on one side of Moving Mold Base 2. A Front Mold 13 is installed on one side of Moving Mold Base 2, and a Mold Cavity 9 is provided on one side of Static Mold Base 8. By using the demolding components, the demolding time of the staff can be reduced and the work efficiency can be improved.

[0027] Among them, the demolding component includes a Mounting Groove 19. A Slide Block 17 is installed inside the Mounting Groove 19. A pair of Springs 18 are installed on one side of the Slide Block 17. One end of the Spring 18 is connected to one side of the Mounting Groove 19. A Through Hole 16 is provided on one side of the Moving Mold Base 2, and the Through Hole 16 communicates with the Mounting Groove 19. A Slide Rod 11 is installed on one side of the Slide Block 17. A Through Slot 12 is provided on one side of the top ends of a pair of Slide Rods 11. A pair of Slide Grooves 10 are provided on both sides of the Static Mold Base 8, and one side of the Slide Groove 10 communicates with the Mold Cavity 9. The top end of the Slide Rod 11 matches the Slide Groove 10. Through the coordinated use of the Slide Block 17, Spring 18, Mounting Groove 19, Through Slot 12 and Slide Groove 10, since the top end of the Slide Rod 11 matches the Slide Groove 10, the material in the Mold Cavity 9 can flow into the Through Slot 12. When the injection molding is completed, a part of both ends of the model is in the Through Slot 12. At this time, both ends of the model are connected to the Slide Rod 11. When the Moving Mold Base 2 starts to move to one side, the Slide Block 17 slides in the Mounting Groove 19, and at the same time, the Slide Rod 11 extends outward under the elastic force of the Spring 18, and the model completely detaches from the Mold Cavity 9 along with the Slide Rod 11 and detaches from the Rear Mold 20. At this time, the staff can take down the model. This method is simple to operate, saves energy consumption, has a low cost, reduces the demolding time and improves the work efficiency.

[0028] Among them, the Slide Block 17 matches the Mounting Groove 19, and the Slide Rod 11 matches the Through Hole 16.

[0029] Among them, a feed port 7 is provided on one side of the base 1, and a diverter groove 14 is provided inside the movable mold base 2. The diverter groove 14 is connected to the feed port 7, and a plurality of guide grooves 15 are provided on one side of the diverter groove 14. The material can flow quickly into the mold cavity 9 through the diverter groove 14 and the guide groove 15, thereby accelerating mold molding, reducing energy consumption, and improving molding efficiency.

[0030] Among them, the rear mold 20 is installed inside the static mold base 8.

[0031] The front mold 13 and the rear mold 20 are matched to improve the injection molding accuracy.

[0032] Among them, a mounting seat 3 is installed on one side of the static mold seat 8, a mounting frame 4 is installed on one side of the mounting seat 3, a reset mechanism 5 is installed between the mounting seat 3 and the mounting frame 4, and a base 2 6 is installed on one side of the reset mechanism 5.

[0033] The specific usage and function of this embodiment are as follows:

[0034] First, check the integrity of the device. It can be used after confirmation. When using it, first start the equipment and connect the front mold 13 and the rear mold 20 together. At this time, the slide bar 11 is connected to the slide groove 10, and the tail end of the slide bar 11 moves to the installation groove 19 through the extrusion of the spring 18 by the slider 17. The material is injected from the feed port 7, and the material passes through the diversion groove 14 and flows into the guide groove 15, and finally injected into the mold cavity 9. Since the top of the slide bar 11 matches the slide groove 10, the material in the mold cavity 9 can flow into the through groove 12 at the same time and cool. After injection molding, part of the two ends of the model is in the through groove 12. At this time, the model The two ends are connected to the slide bar 11, and when the movable mold base 2 starts to move to one side, the ejection mechanism ejects the model through the ejector pin, and the model is separated from the rear mold 20. The slider 17 slides in the mounting groove 19. At the same time, the slide bar 11 extends outward under the elastic force of the spring 18. The model is completely separated from the mold cavity 9 and the rear mold 20 along with the slide bar 11. At this time, the staff can remove the model and finally clean up the excess parts at both ends of the model. This method is simple to operate, saves energy, has low cost, reduces demoulding time, and improves work efficiency. The overall design of this device is novel and the structure is simple, so it is worthy of widespread promotion and use.
