[0021] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components.

[0022] See Figures 1 to 8 The mold structure capable of rapid demoulding of an embodiment of the present invention comprises an inclined ejector rod 1, an insert block 2 and a cavity 3, one end of the inclined ejector rod 1 is provided with a slide 11, and the other end of the inclined ejector rod 1 is connected to the straight push plate of the mold through a push block 6. The insert block 2 is provided with a slider 21 matching the slide 11 at one end, and the slide 11 and the insert block 2 are penetrated by a limit screw 4, the slide 11 is inclined, and the inclination direction is opposite to the inclination direction of the inclined ejector rod 1, and limiting slide grooves 22 are provided on both sides of the insert block 2, and the wall surface of the cavity 3 is provided with a limiting block 31 matching the limiting slide groove 22, and the edge ends of the insert block 2 and the cavity 3 are provided with a convex edge 5. In the initial state, the convex edge 5 of the insert block 2 is flush with the convex edge 5 of the cavity 3.

[0023] In the above embodiment, one end of the lift rod 1 is provided with a slide 11, which is inclined, and its inclination direction is opposite to the overall inclination direction of the lift rod 1. The other end of the lift rod 1 is connected to the straight push plate of the mold through the push block 6, forming a linkage mechanism. One end of the insert block 2 is equipped with a slider 21 that matches the slide 11 to ensure that the insert block 2 can slide smoothly along the slide 11. In order to stabilize the connection between the two, a limit screw 4 is passed between the slide 11 and the insert block 2 to prevent the insert block 2 and the lift rod 1 from falling off during the demolding process.

[0024] Insert block 2 is designed with limit slots 22 on both sides. These slots mate with limit blocks 31 on the walls of cavity 3, ensuring the stable position of insert block 2 within cavity 3 while also limiting its upward movement. Furthermore, both the insert block 2 and cavity 3 have raised edges 5. In the initial state of the mold, these edges 5 remain flush, creating an undercut 71 on the molded part 7.

[0025] See Figure 7 as well as Figure 8When the injection molding is completed, the straight push plate of the mold begins to move upward, driving the inclined ejector 1 to rise synchronously through the push block 6. The rising action of the inclined ejector 1 then pushes the insert block 2 to slide up along the limit block 31. At this time, the convex edge 5 of the insert block 2 is always located at the undercut 71 of the molded part 7, playing a role in supporting and assisting demolding. As the inclined ejector 1 continues to rise, when one end of it completely breaks away from the restriction of the cavity 3, it will tilt to one side due to the inclined design of the inclined ejector 1 itself. This tilting action causes misalignment between the inclined ejector 1 and the insert block 2, and the end face of the inclined ejector 1 is first demolded from the molded part 7.

[0026] The stop screw 4 plays a crucial role in preventing the lifter 1 from sliding against the insert block 2 during this process, ensuring that the lifter 1 and insert block 2 do not separate during misaligned sliding. As the lifter 1 continues to move, its tilting motion gradually lowers its top end, which in turn lowers the insert block 2. Ultimately, when the flange 5 of the insert block 2 completely clears the undercut 71 of the molded part 7, demolding is complete.

[0027] In summary, the mold structure of the present invention realizes the rapid demoulding of parts with undercuts 71 through the inclined ejector 1, the insert block 2 and the cavity 3, thereby improving production efficiency and reducing the complexity of mold operation.

[0028] See Figures 1 to 8 In another embodiment, the slideway 11 and the slider 21 are both trapezoidal.

[0029] In the above embodiment, the design of the trapezoidal slideway 11 and the trapezoidal slider 21 ensures stability and guidance during the sliding process, effectively preventing deviation or jamming during sliding. Furthermore, the trapezoidal structure facilitates the tilting and driving effect of the lifter 1, allowing the slider 21 to slide smoothly along the slideway 11 to the predetermined position during demolding, achieving rapid and accurate demolding.

[0030] See Figures 1 to 8 In another embodiment, the limiting block 31 gradually narrows from bottom to top.

[0031] In the above embodiment, the stopper 31 is designed to taper from bottom to top, enhancing the stability of the insert block 2 within the mold cavity 3 and preventing shaking or displacement caused by uneven force during the injection and demolding processes. Furthermore, the tapering stopper 31 facilitates smooth sliding of the insert block 2 during demolding, ensuring a smooth demolding process.

[0032] See Figures 1 to 8 In another embodiment, the inclination angle is between 30° and 40°.

[0033] In the above embodiment, the inclination angle is set between 30° and 40°, which can not only ensure that the inclined ejector rod 1 has sufficient driving force during demolding, so that the insert block 2 can smoothly detach from the undercut 71 of the molded part 7, but also avoid structural instability or excessive demolding force caused by excessive angle, thereby ensuring the stability of the mold structure and demolding efficiency.

[0034] See Figures 1 to 8 In another embodiment, transverse grooves 61 are provided on both sides of the inner wall surface of the push block 6, and sliding blocks 12 matching the transverse grooves 61 are provided on both side surfaces of one end of the inclined push rod 1.

[0035] In the above embodiment, transverse grooves 61 are designed on both sides of the inner wall of the push block 6. These grooves are used to guide and constrain the movement trajectory of the lift rod 1. The two side surfaces of one end of the lift rod 1 are equipped with sliding blocks 12 that precisely match the transverse grooves 61. When the mold's push plate moves upward, the push block 6 rises accordingly. The cooperation between the transverse grooves 61 and the sliding blocks 12 ensures that the lift rod 1 can slide stably in the predetermined direction. This design not only enhances the smoothness of the lift rod 1's movement, but also ensures precise control of the lift rod 1 during the demolding process, thereby achieving a fast and reliable demolding operation.

[0036] See Figures 1 to 8 In another embodiment, a limiting groove 62 is further provided on the bottom surface between the two horizontal sliding grooves 61 , and a portion of the inclined ejector rod 1 protrudes relative to the push block 6 , and the protruding portion of the inclined ejector rod 1 is located in the limiting groove 62 .

[0037] In the above embodiment, during the operation of the mold, the limit groove 62 ensures that the inclined ejector rod 1 will not deviate from the predetermined path during the sliding process. Even when the inclined ejector rod 1 is tilted for demolding, it can maintain a stable movement state through the guidance of the limit groove 62, thereby enhancing the overall stability of the mold structure and the reliability of demolding.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of the technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
