[0011] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0012] like Figures 1-8 As shown, a delayed block demolding structure mold includes a base 1, a side mold mechanism 2 fixedly connected to the upper side of the base 1, a fixed seat 3 overlapping the upper side of the side mold mechanism 2, a top plate 4 fixedly connected to the upper side of the fixed seat 3, a bottom mold 5 fixedly connected to the upper middle part of the base 1, a top mold 6 fixedly connected to the lower middle part of the top plate 4, and an injection port 7 fixedly connected to the inner side of the base 1. The side mold mechanism 2 includes a rotating plate 21. The lower side of the rotating plate 21 is fixedly connected to the upper side of the base 1. The upper side of the rotating plate 21 is provided with a plurality of annularly distributed first guide grooves 25 and a plurality of annularly distributed second guide grooves 26. The inner sides of the plurality of first guide grooves 25 are slidably connected to an outer mold 23, and the inner sides of the plurality of second guide grooves 26 are slidably connected to an inner mold 24.

[0013] It should be noted that the outer mold 23, inner mold 24, bottom mold 5, and top mold 6 form a complete mold. Injection molding is achieved by injecting material into the injection port 7. The inner side of the fixing seat 3 is movably sleeved on the outer side of the outer mold 23 to fix the outer mold 23.

[0014] like Figure 6 , Figure 7 As shown, a limiting plate 22 is rotatably connected to the upper side of the base 1, and the limiting plate 22 is located below the rotating plate 21. Several annularly distributed first arc grooves 27 are opened on the upper side of the limiting plate 22. The lower side of the outer mold 23 is synchronously slidably connected to the inner side of the first arc grooves 27. Several annularly distributed second arc grooves 28 are opened on the upper side of the limiting plate 22. The lower side of the inner mold 24 is synchronously slidably connected to the inner side of the second arc grooves 28.

[0015] It should be noted that the limiting plate 22 is equipped with a rotating handle. When the rotating handle is located at the far right, the outer mold 23 and the inner mold 24 move closer to each other, driving the rotating handle to separate the outer mold 23 and the inner mold 24 to complete the demolding.

[0016] like Figure 7 As shown, the first arc groove 27 contains, from the inside out, a first-stage outer arc groove 271, a second-stage outer arc groove 272, and a third-stage outer arc groove 273 that are smoothly connected. The second arc groove 28 contains, from the inside out, a first-stage inner arc groove 281, a second-stage inner arc groove 282, and a third-stage inner arc groove 283 that are smoothly connected. The center of the groove opening of the third-stage outer arc groove 273 and the first-stage inner arc groove 281 coincides with the rotation center of the limiting plate 22.

[0017] It should be noted that the drive handle rotates the limiting plate 22 from right to left. When the outer mold 23 slides inside the outer arc groove 271 of the first stage and the inner mold 24 slides inside the inner arc groove 281 of the first stage, it is the first stage. At this time, the inner mold 24 does not move and the outer mold 23 expands outward. When the outer mold 23 slides inside the outer arc groove 272 of the second stage and the inner mold 24 slides inside the inner arc groove 282 of the second stage, it is the second stage. The outer mold 23 and the inner mold 24 expand outward synchronously. When the outer mold 23 slides inside the outer arc groove 273 of the third stage and the inner mold 24 slides inside the inner arc groove 283 of the third stage, the outer mold 23 does not move and the inner mold 24 continues to expand outward.

[0018] The working principle of this utility model is as follows: A rotating handle is provided on the limiting plate 22. When the rotating handle is located at the rightmost position, the outer mold 23 and the inner mold 24 move closer together. Driving the rotating handle causes the outer mold 23 and the inner mold 24 to separate and complete demolding. Driving the handle from right to left causes the limiting plate 22 to rotate. When the outer mold 23 slides inside the first stage outer arc groove 271 and the inner mold 24 slides inside the first stage inner arc groove 281, this is the first stage. At this time, the inner mold 24 does not move, and the outer mold 23 expands outward. When the outer mold 23 slides inside the second stage outer arc groove 272... On the side, when the inner mold 24 slides inside the inner arc groove 282 in the second stage, it is the second stage. The outer mold 23 and the inner mold 24 expand outward synchronously. When the outer mold 23 slides inside the outer arc groove 273 in the third stage and the inner mold 24 slides inside the inner arc groove 283 in the third stage, the outer mold 23 does not move, and the inner mold 24 continues to expand outward. By dividing the first arc groove 27 and the second arc groove 28 into three segments, the outer mold 23 and the inner mold 24 can move in three stages, thereby delaying the movement of the inner mold 24, improving production efficiency and increasing the product qualification rate.
