[0022] As Figures 1 to 5As shown, the slider demolding structure of the embodiment comprises a first sliding assembly 1 and a second sliding assembly 2 arranged between an upper die 100 and a lower die 200. The upper die 100 and the lower die 200 are provided with a cavity 10 for forming a product. By arranging the first sliding assembly 1 and the second sliding assembly 2, the horizontal and vertical movements can be performed synchronously during the demolding process, realizing efficient and stable demolding operation. The first sliding assembly 1 comprises a first slider 11, a linkage block 12 and a first elastic member 13. The first slider 11 is arranged on the lower die 200 and serves as a horizontal movement component. During the demolding process, the first slider 11 slides away from the cavity 10, ensuring smooth demolding of the product. The linkage block 12 is connected to the first slider 11 at one end and arranged correspondingly to the cavity 10 at the other end. During demolding, the first slider 11 moves horizontally. The first elastic member 13 is arranged horizontally and abuts against the first slider 11. The first elastic member 13 provides horizontal elastic force to move the first slider 11. The second sliding assembly 2 comprises a second slider 21, a positioning member 22 and a second elastic member 23. The positioning member 22 is arranged on the lower die 200 and serves to limit the movement range of the second slider 21, ensuring that the slider can move along the set trajectory. The second elastic member 23 is arranged vertically on the positioning member 22. One end of the second elastic member 23 abuts against the second slider 21. The second slider 21 is arranged on the positioning member 22 through a through hole 24 and slides vertically along the positioning member 22. Through the cooperation of the first slider 11 and the second slider 21, the slider can move horizontally and vertically during the demolding process, ensuring smooth demolding and reducing damage to the product surface. The first and second elastic members provide elastic force to enable the two sliders to slide smoothly during demolding, avoiding interference or jamming. In addition, the demolding force can be buffered to avoid deformation or damage of the product due to uneven stress. The positioning member 22 is provided with a limiting ring 221 at the top to prevent the second slider 21 from sliding out, ensuring stable and reliable movement of the slider. The second slider 21 is arranged adjacent to the first slider 11. When the second slider 21 descends, the first slider 11 moves towards the cavity 10. When the second slider 21 rises, the first slider 11 moves away from the cavity 10.

[0023] When the slider demolding structure of the embodiment is used: the first slider 11 and the second slider 21 are both in the initial position, the mold is closed, and the plastic fills the cavity 10. When the mold is opened, the second slider 21 starts to rise under the action of the elastic force, and at the same time, the first slider 11 moves away from the cavity under the action of the elastic force, releasing the product. The first and second elastic members can be made of elastic materials such as compression springs, leaf springs or elastic rubber blocks to meet different mold requirements. As an improvement, the positioning member 22 can be made of an adjustable structure, so that the sliding stroke of the second slider can be adjusted according to the demolding requirements of different products. The positioning member 22 of the embodiment is a screw.

[0024] Further, the first slider 11 is provided with a first contact surface 111 and a second contact surface 112, the first contact surface 111 is located above the second contact surface 112, the angle a1 between the first contact surface 111 and the plane X is smaller than the angle a2 between the second contact surface 112 and the plane Y, and the plane X and the plane Y are parallel planes. The second slider 21 comprises a first matching surface 211 and a second matching surface 212, the first matching surface 211 is located above the second matching surface 212, the second matching surface 211 abuts against the first contact surface 111 when the second slider 21 is located at the top dead center, the second matching surface 212 abuts against the second contact surface 112 when the second slider 21 is located at the bottom dead center, and the first matching surface 211 abuts against the first contact surface 111. Through the above technical scheme, when the upper die 100 is pressed downward, the second slider 21 moves downward under pressure, and when the second slider 21 moves to the bottom dead center, the two contact surfaces correspond to the two matching surfaces respectively, which can improve the positioning stability and avoid the first slider from shaking during forming. As an improvement, the contact surface and the matching surface are made of wear-resistant materials such as high-strength alloys or ceramic coatings, or a gasket is provided, so as to improve the durability of the contact surface and reduce wear.

[0025] Further, the first slider 11 is provided with a first contact surface 111 and a second contact surface 112, the first contact surface 111 is located above the second contact surface 112, the angle a1 between the first contact surface 111 and the plane X is smaller than the angle a2 between the second contact surface 112 and the plane Y, and the plane X and the plane Y are parallel planes. The second slider 21 comprises a first matching surface 211 and a second matching surface 212, the first matching surface 211 is located above the second matching surface 212, the second matching surface 211 abuts against the first contact surface 111 when the second slider 21 is located at the top dead center, the second matching surface 212 abuts against the second contact surface 112 when the second slider 21 is located at the bottom dead center, and the first matching surface 211 abuts against the first contact surface 111. Through the above technical scheme, when the upper die 100 is pressed downward, the second slider 21 moves downward under pressure, and when the second slider 21 moves to the bottom dead center, the two contact surfaces correspond to the two matching surfaces respectively, which can improve the positioning stability and avoid the first slider from shaking during forming. As an improvement, the contact surface and the matching surface are made of wear-resistant materials such as high-strength alloys or ceramic coatings, or a gasket is provided, so as to improve the durability of the contact surface and reduce wear.

In addition, the slider has strong load bearing capacity and is not prone to damage.
