[0015] (III) Beneficial Effects

[0016] In rapid demolding, the product quality is easily affected by the demolding force during the secondary ejection process using a lifting plate and ejector pins. The secondary ejection structure can reasonably distribute the demolding force, avoiding damage to the product caused by excessive demolding force in a single ejection. During the first ejection, a smaller demolding force is applied evenly to the product, causing the product periphery to separate slowly from the mold and reducing stress concentration. During the second ejection, the ejection position and force are precisely adjusted according to the specific shape and structural characteristics of the product to ensure that the product leaves the mold smoothly and completely, preventing defects such as scratches and deformation on the surface of automotive products, ensuring that product quality meets strict automotive industry standards, and improving the product yield.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a demolding structure, such as Figures 1 to 4 As shown, the system includes an automobile base mold 1. A molding cavity 101 is formed on the upper surface of the automobile base mold 1. Concave grooves are provided on both sides of the automobile base mold 1 near the molding cavity 101. Side fixing plates 2 are fixedly installed on the surface of the molding cavity 101 near the concave grooves. A protruding surface 102 is provided on one side of the automobile base mold 1 near the molding cavity 101. Limiting blocks 3 are fixedly installed on both sides of the upper surface of the concave grooves. A stepped end 301 is provided at the top of one side surface of the limiting block 3. An arched slider 4 is slidably connected to the surface of the stepped end 301. An inclined surface A401 is formed on one side of the upper surface of the arched slider 4. Undercut ends 402 are provided on both sides of the arched slider 4. One side surface of the inverted end 402 is movably connected to the stepped end 301. One side of the limiting block 3 is attached to the surface of the side plate 2. A locking element 5 is fixedly installed on the back of the limiting block 3. A lifting plate 6 is movably sleeved on the upper surface of the arched slider 4. One side of the lower surface of the lifting plate 6 is provided with a slope B601. The slope B601 on the lower surface of the lifting plate 6 is attached to the slope A401 on one side of the arched slider 4. One side surface of the locking element 5 is fixedly installed on the surface of the car bottom mold 1 by bolts. A moving groove 602 is opened on one side surface of the lifting plate 6. A connecting spring piece 403 is provided at the middle of the upper surface of the arched slider 4.

[0025] Securely fixed to the limiting block 3 with screws, the two limiting blocks 3 are opposite each other and are provided with limiting grooves for the arched slider 4. During the sliding process of the arched slider 4, it moves along the path defined by the limiting block 3, ensuring the stability and accuracy of its movement. Similarly, the paired protruding surfaces 102 are placed at one end of the arched slider 4. At the same end where the locking element 5 is located, the protruding surfaces 102 effectively limit the arched slider 4, thereby preventing the arched slider 4 from accidentally popping out, and providing a solid guarantee for the safe and stable operation of the entire demolding structure.

[0026] To achieve the ideal coordination effect, the inclined surfaces A401 on the lifting plate 6 and the arched slider 4 have the same slope on the same side. The inclined surface B601 at the lower end of the lifting plate 6 and the inclined surface A401 are both inverted trapezoidal in shape. It is worth noting that the upper bottom edge of the lifting plate 6 is shorter than the lower bottom edge of the inclined surface A401 on the arched slider 4. This not only ensures that the lifting plate 6 can pass smoothly through the inclined surface A401, but more importantly, during the movement of the lifting plate 6, the interaction force between the inclined surfaces A401 and B601 causes the arched slider 4 to slide, thereby achieving efficient linkage between the lifting plate 6 and the arched slider 4.

[0027] Spring 11 is tightly connected to arched slider 4 at one end and is firmly connected to protruding surface 102 at the other end. After the second ejection process is successfully completed, spring 11 will play its elastic reset function, helping arched slider 4 to quickly return to its initial position. During the dynamic process of interaction between lifting plate 6 and arched slider 4, spring 11 will remain in a compressed state, making full preparation for subsequent reset actions.

[0028] A pin 7 is bolted through the top of one side of the connecting spring 403. One side of the connecting bolt of the connecting spring 403 is slidably engaged in the moving groove 602 and adapted to the lifting plate 6. A through hole is opened on the upper surface of the lifting plate 6. One end of the pin 7 is connected through the through hole. The upper surface of the pin 7 is movably overlapped with the car top mold 8. A through groove adapted to the mold cavity 101 is opened on the lower surface of the car top mold 8. A receiving plate 9 is fixedly installed on the lower surface of the car top mold 8. A template 10 is connected through the mold cavity 101 on the upper surface of the car bottom mold 1. A spring 11 is connected between the arched slider 4 and the protruding surface 102.

[0029] The upper vehicle top mold 8 is provided with a movable hole that matches the lifting plate 6. The lifting plate 6 is smoothly connected to the lower vehicle bottom mold 1 through this hole. Especially during the second ejection stage, the lifting plate 6 will be tightly pressed against the lower vehicle bottom mold 1 to form a stable support structure. In order to further improve the positioning of the lifting plate 6 during operation, the lower vehicle bottom mold 1 is movably connected to the upper ejector pin 7 at the connection with the lifting plate 6.

[0030] In the entire secondary ejection and demolding mechanism, when an upward ejection force is applied from the outside, the ejector pin 7 moves continuously upward under the drive. During the ejection process, the ejector pin 7 moves along the moving groove 602 inside the lifting plate 6. At the same time, the connecting spring 403 is subjected to pressure from the side. Under the action of this pressure, the connecting spring 403 guides the internal ejector pin 7, causing it to move upward until the top of the car mold 8 is successfully ejected for the second time. This process efficiently and accurately completes the secondary ejection and demolding operation of the car mold, greatly improving the demolding efficiency and quality of the car mold, and laying a solid foundation for the large-scale, high-quality production of automotive parts.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
