[0002] The mold core is a key mold term in the manufacturing industry. It constitutes the part of the product space, especially the part of the inner surface of the molded product. From the appearance of the product mold, the convex part is the core, and the concave part is called the cavity. The core and the cavity appear in pairs. When the cavity and the core of the mold are molded together, the space formed between them is the shape of the mold product. The core is a key part of the inner surface of the molded plastic part in the mold, and its quality directly affects the quality of the part and the life of the mold. In the process of mold manufacturing and use, the mold core is usually a movable mold part, which cooperates with parts such as the fixed plate to ensure the accuracy and stability of the mold through precise processing and matching. This matching relationship plays a very important role in the life and production efficiency of the mold.

[0003] According to different classification standards, there can be many types of core cavities. For example, according to the number of parts formed at one time, it can be divided into one mold with one cavity or one mold with multiple cavities; according to the structural composition, it can be divided into four types: integral fixed mold + integral movable mold, split fixed mold + integral movable mold, integral fixed mold + split movable mold, and split fixed mold + split movable mold. The mold core is a key component in the mold, which is used to form the internal shape and structure of the product. However, the traditional fixed mold core has shortcomings in positioning accuracy, adaptability and ease of operation. Utility Model Content

The design of the mold weight reduction cavity 6 and the clamping ring 7 further enhances the accuracy of positioning, so that the mold core 5 can maintain a high degree of accuracy during the positioning and movement process. The use of the guide adjustment motor 11 also simplifies the movement and adjustment process of the mold core 5, thereby improving production efficiency.

[0022] Reference Figures 1 to 4 A mold limiting frame 21 is fixedly disposed on the outer periphery of the mold base 1 , and mold guide plates 22 are fixedly disposed on the tops of both sides of the mold limiting frame 21 .

[0023] By adopting the above solution, the stability and durability of the entire structure are ensured through the solid design of the mold base 1, the mold limit frame 21, the mold guide plate 22 and the mold fixing plate 32.

[0024] Reference Figures 1 to 4 The mold base 1 is provided with mold slots 31 on both sides, and a mold fixing plate 32 is clamped inside the mold slots 31.

When it is necessary to move or adjust the position of the mold core 5, the guide screw 10 is driven to rotate by the guide adjustment motor 11, thereby pushing the fixed seat guide block 9 to slide in the guide groove 8. This precise mechanical transmission mechanism enables the mold core 5 to move along a predetermined trajectory, thereby achieving precise positioning. At the same time, the mold weight reduction cavity 6 and the clamping ring 7 design at the bottom of the mold core 5 not only reduce the overall weight of the mold, but also enhance the mold type The core 5 is stable during movement, and the retaining ring 7 is fixedly connected to the mold core 5 to ensure that it will not fall off or be misplaced during movement.
