DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will combine the drawings in the embodiments of the present invention Figures 1-4, the technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the protection scope of the present utility model. Embodiment

[0027] A phenolic mold compound injection molding machine in a central extraction mode includes a base 1. A bottom mold 2 is fixedly installed at the top of the base 1. A rotating shaft column 3 is fixedly installed on one side of the top of the bottom mold 2. A central mold 4 located above the bottom mold 2 is rotatably installed on the surface of the rotating shaft column 3. A top mold 5 located above the central mold 4 is slidably installed on the surface of the rotating shaft column 3. A mold core 6 is embedded and installed at the top of the top mold 5. The bottom of the mold core 6 extends into the interior of the central mold 4. A convex tooth block 8 is fixedly connected to one side of the central mold 4. A convex tooth ring 9 adapted to the convex tooth block 8 is fixedly installed by embedding on one side of the top of the bottom mold 2. A top material assembly is arranged on one side of the base 1. A through hole is formed on one side of the top of the top mold 5. A liquid injection pipe 7 inserted into the through hole is fixedly connected to one side of the mold core 6. The bottom end of the liquid injection pipe 7 is communicated with the inner cavity of the central mold 4.

[0028] The specific usage process is as follows: First, the top mold 5 and the bottom mold 2 are clamped together. When operating, start the electric push rod 19 to drive the pressing block 20 to move downward. Then, the pressing block 20 will press on the top mold 5, and then push the top mold 5 downward until the two locking blocks 10 are combined together. In this way, it can provide assistance for the clamping of the mold and convenience for the user's work. Among them, when the pressing block 20 presses down the top mold 5 for clamping, the top mold 5 will compress the spring 12. When it is necessary to open the mold, after the pressing block 20 moves upward, under the action of the spring 12, the top mold 5 will be bounced upward to complete the mold opening, providing convenience for the user's work. Then, the mold core 6 is placed into the top mold 5. At the same time, the bottom of the mold core 6 also enters the inner cavity of the central mold 4. When installing the mold core 6, the liquid injection pipe 7 should be aligned with the through hole on the top mold 5 and inserted. Among them, after the top mold 5 and the bottom mold 2 are clamped, the two locking blocks 10 are also combined together. Then, the locking nut 11 can be installed on the two locking blocks 10 at the same time, thereby tightly locking the bottom mold 2 and the top mold 5 together to ensure the stability of the mold clamping work and provide convenience for the user's work. In this way, the entire mold is clamped. At this time, the pressing block 20 can be raised or not, depending on the actual situation. The whole process is completed automatically and quickly by the mechanical structure, improving the efficiency of the user's mold clamping work. Then, plastic solution is injected into the complete mold through the liquid injection pipe 7. After the product is formed, the user holds the handle 13 and turns it to the side of the ejector assembly. It should be noted that since the top mold 5 and the bottom mold 2 are stationary, and the top mold 5 can only slide up and down on the surface of the rotating shaft column 3, when the central mold 4 rotates, it is equivalent to cutting the product from the scrap. Therefore, the finally obtained product is relatively complete, reducing the need for post-processing. When the central mold 4 rotates to the upper part of the ejector assembly, the user presses down the pressing rod 15. Then, the pressing rod 15 drives the top block 16 to flip upward, and at the same time, the top block 16 also moves out of the fixed frame 14, thereby ejecting the product in the central mold 4. Then, the product falls onto the conveying device 17 and is conveyed out for collection, providing convenience for the user's work. Then, the central mold 4 is pushed back to its original position to prepare for the next work, providing convenience for the user's work. Among them, when the central mold 4 rotates, the convex tooth block 8 will move on the upper surface of the convex tooth ring 9. It should be noted that the convex tooth ring 9 and the convex tooth block 8 should be made of elastic materials. In this way, it can meet the requirement that during work, the convex tooth ring 9 is stationary, while the convex tooth block 8 can smoothly rotate with the central mold 4. And with the cooperation of the convex tooth block 8 and the convex tooth ring 9, a "click, click, click" prompt sound will be emitted to prompt the user. At the same time, it also generates a damping effect on the rotation of the central mold 4, preventing the central mold 4 from moving randomly, ensuring the stability of the central mold 4 during discharging and also ensuring the stability of the central mold 4 after mold clamping, providing convenience for the user's work.

[0029] Therefore, a structure design that allows for central core pulling is adopted. After the phenolic molding compound product is molded, the user can rotate the central mold and open it to the side. Then, after quickly ejecting and sending out the molded product, the mold is closed for the next operation, realizing rapid and efficient mold opening, discharging, and mold closing, saving the time spent in product production, improving production efficiency, and providing convenience for the user's work.

[0030] On one side of the bottom mold 2 and the top mold 5, a locking block 10 is fixedly connected, and a locking nut 11 is threadedly installed on the surface of the two locking blocks 10.

[0031] Specifically, with the setting of the locking block 10 and the locking nut 11, the two locking blocks 10 can be combined together, and then the locking nut 11 can be installed on the two locking blocks 10 at the same time, thereby tightly locking the bottom mold 2 and the top mold 5 together, ensuring the stability of the mold closing operation and providing convenience for the user's work.

[0032] A spring 12 is sleeved on the surface of the rotating shaft column 3. The top end of the spring 12 is fixedly connected to the top mold 5, and the bottom end of the spring 12 is fixedly connected to the rotating shaft column 3.

[0033] Specifically, with the setting of the spring 12, when the pressing block 20 presses down the top mold 5 to close the mold, the top mold 5 will compress the spring 12. When mold opening is required, after the pressing block 20 moves upward, under the action of the spring 12, the top mold 5 will be bounced upward to complete mold opening, providing convenience for the user's work.

[0034] The ejector assembly includes a fixed frame 14 fixedly installed on the base 1. A top block 16 adapted to the central mold 4 is rotatably installed up and down inside the fixed frame 14, and a pressing rod 15 is fixedly installed on the outside of the top block 16.

[0035] Specifically, with the setting of the fixed frame 14, the pressing rod 15, and the top block 16, the ejector assembly is used to eject the product inside the central mold 4. During operation, the user presses down the pressing rod 15, and then the pressing rod 15 drives the top block 16 to rotate upward. At the same time, the top block 16 also moves out of the fixed frame 14, thereby ejecting the product inside the central mold 4. Then, the product falls onto the conveying device 17 and is conveyed out for collection, providing convenience for the user's work.

[0036] A conveying device 17 is fixedly installed on one side of the base 1, and the conveying device 17 is adapted to the ejector assembly.

[0037] Specifically, with the setting of the conveying device 17, after the ejector assembly ejects the molded product out of the mold, the product falls onto the conveying device 17 and is then conveyed out for collection and standby, providing convenience for the user's work.

[0038] One side of the central mold 4 is fixedly installed with a handle 13. The handle 13 is in an L shape, and the surface of the handle 13 is provided with anti-slip patterns.

[0039] Specifically, due to the setting of the handle 13 and the anti-slip patterns, when the user withdraws the mold, the user holds the handle 13. Since the anti-slip patterns are provided on the handle 13, the user will not slip when holding the handle 13 during work, providing convenience for the user's work.

[0040] One side of the base 1 is fixedly installed with a mounting frame 18. The top of the mounting frame 18 is fixedly installed with an electric push rod 19. The output end of the electric push rod 19 penetrates to the inside of the mounting frame 18 and is fixedly installed with a pressing block 20 located directly above the top mold 5.

[0041] Specifically, due to the setting of the mounting frame 18, the electric push rod 19 and the pressing block 20, when working, start the electric push rod 19 to drive the pressing block 20 to move downward. Then the pressing block 20 will press on the top mold 5, and then push the top mold 5 downward until the two locking blocks 10 are combined together. In this way, it can provide assistance for the mold closing, providing convenience for the user's work.

[0042] It should be noted that for the functions to be realized by each hardware in the present invention, there are a large number of mature technologies as support, which belong to the prior art. The essence of the present invention lies in optimizing the combination of existing hardware and its connection methods for a specific application scenario to meet the adaptation requirements in the specific application scenario and solve the problems raised in the background technology (without involving the improvement of the software inside the hardware).

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
