Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to an integrated mold consisting of a mold core and a slider. Background Art

[0002] Sliders are a common feature in injection mold design, used to create lateral holes, grooves, and other complex geometric shapes in molded products. Traditional slider designs typically include multiple components, including a slider seat, wear pads, and a shovel mechanism. These components not only increase mold manufacturing complexity and cost, but also occupy a significant amount of internal mold space, resulting in a larger overall mold size and limiting its compatibility with various machine tools. Furthermore, conventional sliders exhibit significant frictional losses, which can lead to unstable movement during the injection molding process, compromising product quality.

[0003] As demand for injection molded products grows more diverse and complex, the number of mold cavities (i.e., the number of products that can be molded simultaneously in a mold) is gradually increasing. This further increases the number and variety of sliders, making mold design and manufacturing more complex and requiring longer production cycles. Existing technologies typically employ a combination of multiple parts to solve the problem of slider-to-mold fit. This not only increases material, processing, and labor costs, but also prolongs the overall mold processing cycle and increases the size and weight of the mold. Consequently, some larger molds can only be produced on specific, dedicated machines, limiting production flexibility and efficiency. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See Figures 1 to 3As shown, the utility model provides an integrated mold of a mold core and a slider 12, comprising: a fixed mold core 100, a movable mold core 200, a slider 12, and an inclined guide column 24. When the mold is closed, the movable mold core 200 is driven by an external drive device to move toward the fixed mold core 100, so that the movable mold core 200 and the fixed mold core 100 are matched, and in the process of the movable mold core 200 rising, the movable mold core 200 drives the inclined guide column 24, so that one end of the inclined guide column 24 is inserted into the slider 12, so that the slider 12 moves toward the mold closing position of the movable mold core 200 and the fixed mold core 100, so that the three are enclosed to form an injection cavity of the injection molded product. When the mold is separated, the moving direction of the movable mold core 200 is opposite to the moving direction of the movable mold core 200, driving the inclined guide column 24, so that one end of the inclined guide column 24 pushes away the slider 12, so that the slider 12 is away from the injection cavity, thereby realizing the demolding of the injection molded product.

[0030] The above-mentioned mold closing and parting not only reduces the friction of the slider 12 during movement, but also improves the stroke positioning of the slider 12 after movement, ensures that the slider 12 can separate quickly and smoothly, and improves the quality and production efficiency of injection molded products.

[0031] Specifically, a molding end portion 11 is provided on the fixed mold core 100, and a slider 12 is provided on one side of the molding end portion 11, wherein the right end surface of the slider 12 contains a molding side portion 121, and the molding side portion 121 is a special-shaped end surface used for injection molded products, which can be designed according to the actual shape of the injection molded products. Connected to the molding side portion 121 is a second vertical end portion 122, and the second vertical end portion 122 cooperates with the first vertical end portion 13 of the fixed mold core 100, that is, the second vertical end portion 122 abuts against the first vertical end portion 13. When the slider 12 moves, the stroke of the slider 12 can be limited, and the size limit of the injection molded product can also be met.

[0032] The movable mold core 200 is provided with a forming groove 21 that mates with the forming end 11. Inside the groove is an inclined guide post 24 that extends out of the groove and into the slider 12. Slanted holes 126 are provided on the upper and lower ends of the slider 12 to mate with the inclined guide posts 24. As long as both are tilted, the inclined guide posts 24 can move the slider 12 left and right during the lifting process.

[0033] A protrusion 124 is provided on the left end surface of the slider 12 to separate the first limiting end 123 from the second limiting end 125 .

[0034] The fixed mold core 100 is provided with a limit stud 17, which abuts against the first limit end 123. By setting the limit stud 17 and the first vertical end 13, the movement of the slider 12 is limited to a certain spatial range to meet the needs of mold production.

[0035] Furthermore, a slider 12 is embedded within the fixed mold core 100. An insert 14 is provided on the slider 12, and a T-slot 15 is provided within the fixed mold core 100 to mate with the insert 14. The insert 14 is a T-shaped block that mates with the T-slot 15. The shapes of the two are not shown in the figure, but are conventional. This prevents the slider 12 from detaching from the fixed mold core 100 during mold separation, effectively integrating it into the fixed mold core 100. This reduces the overall mold size, saves space, and allows the mold to be compatible with a wider range of machines, improving production flexibility and efficiency.

[0036] In addition, when the slider 12 moves on the fixed mold core 100, it will engage with the positioning members 18 provided on the fixed mold core 100. There are at least two positioning members 18, which are arranged at intervals on the fixed mold core 100. The positioning members 18 include: a base 181 provided on the fixed mold core 100, a spring 182 provided in the base 181, and a positioning glass bead 183 connected to one end of the spring 182. At the same time, a groove 19 for the positioning glass bead 183 is provided on the upper surface of the slider 12. When the mold is opened, the first limiting end 123 of the slider 12 moves to abut against the limiting stud 17. At this time, the slider 12 squeezes the positioning glass bead 183 and causes the positioning glass bead 183 to engage with the groove 19, thereby ensuring that the slider 12 moves quickly and smoothly, and also ensuring that the inclined guide column 24 is accurately inserted into the slider 12 when the mold is closed.

[0037] An assembly space 22 communicating with the molding groove 21 is provided within the movable mold core 200. An elastic member 23 is provided on one sidewall of the assembly space 22, which abuts against the second limiting end 125. The elastic member 23 can be made of rubber. When the slider 12 is driven to the injection position by the inclined guide post 24 and the fixed mold core 100 and the movable mold core 200 are closed, the elastic member 23 applies a force to the slider 12, causing the second vertical end 122 to abut against the first vertical end 13. Furthermore, the molding side 121 of the slider 12 can be precisely moved to the desired position in the injection cavity, ensuring the molding quality and qualified rate of the product.

[0038] The bottom height of the assembly space 22 in the movable mold core 200 is higher than the bottom height of the molding groove 21 in order to ensure the cavity to be molded for the injection molded product and also reduce the flow of the injection colloid.

[0039] A positioning groove 16 is provided on the fixed mold core 100, and the positioning groove 16 cooperates with one end of the inclined guide column 24 extending from the inclined hole 126. The inclined guide column 24 can self-center during movement, helping the mold parts to be more accurately aligned when closing, improving the convenience of mold operation, and at the same time, reducing the movement or offset of the mold during use, thereby ensuring the dimensional accuracy of the product.

[0040] In the mold, the molding side portion 121 , the molding end portion 11 and the molding groove 21 enclose and form an injection molding cavity.

[0041] And by removing many parts such as the traditional slider 12 seats, wear-resistant plates and shovel mechanism, material costs, processing costs and labor costs are saved, and the overall mold processing cycle is shortened.

[0042] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
