[0015] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0016] Please refer to Figures 1 to 3 , the precision mold assembly of the embodiment of the present utility model includes a template 1; a mold core 2; two auxiliary sliders 3 respectively embedded in the mold core 2 from both sides, and the auxiliary sliders are provided with through holes; a pull rod 4, one end of the pull rod 4 is connected to the auxiliary slider 3; a pulling device 5 provided on the template 1, and the pulling device 5 drives the pull rod 4 to push and pull back and forth; a rotating rod 6 provided in the through hole of the auxiliary slider 3; and a rotating device 7 provided on the template 1, and the rotating device 7 drives the mold core 2 to rotate.

[0017] In the above embodiments, on both sides of the mold core 2, two auxiliary sliders 3 are embedded and designed. They are closely combined with the mold core 2 and are provided with through holes inside. These through holes are used to form cylindrical holes during material molding. One end of the extraction rod 4 is connected to the auxiliary slider 3, and the other end is connected to the extraction device 5 on the template 1. The extraction device 5 is responsible for controlling the movement of the auxiliary slider 3 by pushing and pulling the extraction rod 4 back and forth. During the mold forming stage, the material will be molded along the through holes of the auxiliary slider 3 to form the required cylindrical holes. The rotating rod 6 is arranged in the through hole of the auxiliary slider 3. It does not directly participate in the molding process but plays an important role in the demolding stage. When the mold forming is completed, demolding operation is required. At this time, the rotating device 7 starts to work, driving the mold core 2 to rotate slightly. Since the rotating rod 6 is located in the through hole of the auxiliary slider 3, the rotation of the mold core 2 will cause the rotating rod 6 to sway left and right in the through hole. This sway slightly pries open the two auxiliary sliders 3, creating conditions for demolding. Once the auxiliary sliders 3 are slightly pried open, the extraction device 5 can extract the auxiliary sliders 3 from the mold core 2 through the extraction rod 4. During this process, the extraction device 5 will precisely control the movement of the extraction rod 4 to ensure that the auxiliary sliders 3 are smoothly detached from the mold core 2, avoiding damage to the molded product. Finally, when the auxiliary sliders 3 are completely extracted, the mold can be opened to take out the molded product. The entire demolding process through the coordinated work of the rotating device 7 and the extraction device 5 realizes the efficient and precise demolding of the mold with cylindrical holes, greatly improving the production efficiency and product quality.

[0018] Please refer to Figures 1 to 3 , in another embodiment, the extraction device 5 includes a base 51 and a first sliding barrel 52. The base 51 is fixedly arranged on the template 1, the first sliding barrel 52 is arranged on the base 51, and the extraction rod 4 is slidably arranged in the first sliding barrel 52.

[0019] In the above embodiments, the extraction device 5 is mainly composed of a base 51 and a first sliding barrel 52. The base 51 is fixedly arranged on the template 1, providing stable support for the entire extraction device 5. The first sliding barrel 52 is installed on the base 51, and a sliding track is designed inside to accommodate the sliding of the extraction rod 4. One end of the extraction rod 4 is connected to the auxiliary slider 3, and the other end is slidably arranged in the sliding track of the first sliding barrel 52. This design enables the extraction rod 4 to be pushed and pulled back and forth under the guidance of the sliding barrel, thereby controlling the movement of the auxiliary slider 3 in the mold. When demolding is required, an external driving mechanism (such as a cylinder, a motor, etc.) is used to push the extraction rod 4 to slide in the first sliding barrel 52, thereby driving the auxiliary slider 3 to gradually separate from the mold core 2. This structural principle ensures the stability and reliability of the demolding process and improves the use efficiency of the mold.

[0020] Please refer to Figures 1 to 3, in another embodiment, the rotating device 7 includes a fixed base 71, a second sliding barrel 72, a rack 73, and a gear seat 74. The fixed base 71 is fixedly arranged on the template 1. The second sliding barrel 72 is arranged on the fixed base 71. The second sliding barrel 72 is connected to the rack 73. The rack 73 is in tooth engagement with the gear seat 74. The gear seat 74 is connected to the mold core 2.

[0021] In the above embodiment, the fixed base 71 serves as the foundation of the entire rotating device 7 and is stably fixed on the template 1 to ensure the stability of the device during operation. The second sliding barrel 72 is arranged on the fixed base 71 and is connected to the rack 73 to drive the movement of the rack 73 through sliding or linear motion. The rack 73 and the gear seat 74 are connected by tooth engagement, which can ensure the accurate and stable transmission of motion between the two. When the rack 73 moves driven by the second sliding barrel 72, the gear seat 74 will rotate accordingly, and then drive the mold core 2 connected thereto to rotate. By adjusting the amount of movement of the second sliding barrel 72, the relative positions of the rack 73 and the gear seat 74 can be accurately controlled, thereby achieving precise control of the rotation angle of the mold core 2. This structural principle not only ensures the smoothness of the mold during the demolding process but also improves the flexibility and adaptability of the mold.

[0022] Please refer to Figures 1 to 3 , in another embodiment, a sealing structure is provided between the ejector rod 4 and the mold core 2.

[0023] In the above embodiment, this sealing structure is designed to ensure that during the molding and demolding processes of the mold, materials will not leak from the gap between the ejector rod 4 and the mold core 2, and at the same time prevent external impurities from entering the mold interior and affecting the product quality. The sealing structure is usually made of flexible materials such as rubber or polymer seals, which have good elasticity and sealing performance. When the ejector rod 4 moves back and forth driven by the ejecting device 5, the sealing structure can closely adhere to the contact surface between the ejector rod 4 and the mold core 2 to form an effective sealing barrier. This closely adhering design can not only effectively prevent material leakage but also provide necessary lubrication when the ejector rod 4 moves, reduce the frictional resistance, and make the demolding process smoother.

[0024] Please refer to Figures 1 to 3 , in another embodiment, the base 51 is provided with a first positioning rod.

[0025] In the above embodiment, the first positioning rod is fixedly connected to the base 51. When the extraction rod 4 slides driven by the extraction device 5, the first positioning rod will cooperate with the corresponding structure (such as a notch or a protrusion) on the extraction rod 4 to form a positioning and locking mechanism. This cooperation can prevent the extraction rod 4 from shifting or shaking during the sliding process, thus ensuring the stability and accuracy of the extraction rod 4. In addition, the first positioning rod can also provide obvious tactile feedback when the extraction rod 4 is fully inserted or withdrawn, helping the operator accurately judge the position state of the extraction rod 4.

[0026] Please refer to Figures 1 to 3 , in another embodiment, the fixed seat 71 is provided with a second positioning rod.

[0027] In the above embodiment, the second positioning rod is fixed on the fixed seat 71 during the rotation of the mold. This design can ensure that the mold core 2 maintains an accurate position and angle during rotation, avoiding affecting the overall performance and product quality of the mold due to the slight deviation generated during the rotation process. In addition, the second positioning rod can also withstand a certain lateral force and torque, improving the rigidity and stability of the mold. During the long-term use of the mold, this design can maintain the accuracy and stability of the mold and extend the service life of the mold.

[0028] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, can make some changes or modifications to the above-disclosed technical content to obtain equivalent embodiments with equivalent changes. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
