[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 , Figure 2As shown, a four-slide synchronous separation mechanism of a storage box injection mold comprises a fixed mold base 1, the inner wall of the fixed mold base 1 is fixedly connected with a guide sleeve 11 in a rectangular array, the inner wall of the guide sleeve 11 is movably sleeved with a guide column 12, the inner wall of the fixed mold base 1 is fixedly connected with a mold core 13 by bolts, the top of the guide column 12 is fixedly connected with a movable mold mechanism 2 by bolts, the bottom of the inner wall of the fixed mold base 1 is slidably connected with a limiting mechanism 3, the movable mold mechanism 2 comprises a movable mold base 21, the inner wall of the movable mold base 21 is fixedly connected with the top of the guide column 12 by bolts, the limiting mechanism 3 comprises a pad 31, the outer wall of the pad 31 is slidably connected with the bottom of the inner wall of the fixed mold base 1, the inner wall of the pad 31 is movably connected with a storage box 4, the top of the storage box 4 is plugged into the bottom of the movable mold base 21, and the inner wall of the storage box 4 is movably sleeved with the outer wall of the mold core 13.

[0024] The mold is opened by the fixed mold base 1 and the movable mold base 21 so that the outer wall of the mold core 13 is no longer in contact with the outer wall of the storage box 4, and then the movable mold mechanism 2 and the limiting mechanism 3 cooperate with each other to perform complete demoulding.

[0025] like Figure 2 , Figure 4 , Figure 5 As shown, the front and rear positions of the left and right parts of the movable mold base 21 are movably sleeved with an inclined guide column 22, the outer wall of the inclined guide column 22 is movably sleeved with an inclined slider 24, the outer wall of the inclined slider 24 is slidably connected to the inner wall of the fixed mold base 1, the top of the inclined slider 24 is inserted into the inner wall of the movable mold base 21, the bottom end of the inclined slider 24 overlaps the top of the pad 31, and the outer wall of the inclined slider 24 overlaps the outer wall of the storage box 4, and the left and right parts of the front and rear parts of the movable mold base 21 are movably sleeved with an inclined guide column 23, the outer wall of the inclined guide column 23 is movably sleeved with an inclined slider 25, the outer wall of the inclined slider 25 overlaps the outer wall of the inclined slider 1, the outer wall of the inclined slider 25 is slidably connected to the inner wall of the fixed mold base 1, the top of the inclined slider 25 is inserted into the inner wall of the movable mold base 21, the bottom end of the inclined slider 25 overlaps the top of the pad 31, and the outer wall of the inclined slider 25 overlaps the outer wall of the storage box 4.

[0026] When the movable mold base 21 moves upward, it drives the inclined guide pillar 1 22 and the inclined guide pillar 23 to move upward synchronously. Because the inclined guide pillar 1 22 and the inclined guide pillar 23 have inclinations, when the movable mold base 21 drives the inclined guide pillar 1 22 and the inclined guide pillar 23 to move upward, the inclined sliding block 1 24 slides on the outer wall of the inclined guide pillar 23, and under the action of the inclined guide pillar 1 22, the inclined sliding block 1 24 translates in the horizontal direction. At the same time, under the action of the inclined guide pillar 23, the inclined sliding block 25 translates in the horizontal direction synchronously, thereby making the outer walls of the inclined sliding blocks 1 24 and the inclined sliding blocks 2 25 no longer contact the storage box 4, thereby demoulding the storage box 4 on four sides at the same time, thereby speeding up the work efficiency and achieving the effect of demoulding on multiple sides at the same time.

[0027] like Figure 2-Figure 4 As shown, the outer wall of the inclined sliding block 24 is fixedly connected to the cylinder 26 by bolts, the output end of the cylinder 26 is fixedly connected to the driving rod 27, the driving rod 27 is in a parallel state with the inclined guide column 22, the top end of the driving rod 27 is rotatably connected to the guide block 28, the outer wall of the guide block 28 is slidably connected to the inner wall of the movable mold base 21, and the guide block 28 has a T-shaped shape.

[0028] When the oil cylinder 26 drives the driving rod 27 to move upward, and drives the movable mold base 21 to move upward synchronously, because the driving rod 27 has an inclination, when the movable mold base 21 moves upward, the guide block 28 slides on the inner wall of the movable mold base 21, and the driving rod 27 is limited and guided by the guide block 28 to prevent the driving rod 27 from extending too much upward. At the same time, it prevents the driving rod 27 from deviating when extending upward, thereby guiding and limiting the driving rod 27, achieving the effect of guiding and limiting.

[0029] like Figure 2 As shown, the four corners of the top of the pad 31 are fixedly connected to the limit block 32 by bolts, the outer wall of the limit block 32 is slidably connected to the inner wall of the fixed mold base 1, the inner wall of the limit block 32 is slidably connected to the bottom of the inclined slide block 1 24 and the inclined slide block 2 25, and the inner wall of the limit block 32 is movably connected to the outer wall of the guide column 12.

[0030] When the inclined slider 1 24 and the inclined slider 2 25 slide, the inner walls of the inclined slider 1 24 and the inclined slider 2 25 are slidably connected to the outer wall of the limit block 32, and the limit block 32 guides the inclined slider 1 24 and the inclined slider 2 25 so that the inclined slider 1 24 and the inclined slider 2 25 will not deviate when sliding.

[0031] The working principle of the utility model is as follows: when the storage box 4 is in use, after the injection molding is completed and demoulding is required, the fixed mold base 1 and the movable mold base 21 are first opened, so that the outer wall of the pad 31 is no longer in contact with the inner wall of the fixed mold base 1, and at the same time, the outer walls of the inclined slide block 1 24 and the inclined slide block 2 25 are no longer in contact with the inner wall of the fixed mold base 1, so that the outer wall of the mold core 13 is no longer plugged with the inner wall of the storage box 4, and the preliminary core pulling and demoulding is completed, thereby making the pad 31 and the limit block 32 on the outer wall of the guide column 12, and the guide column 12 guides the pad 31 and the limit block 32, The backing plate 31 and the limit block 32 can slide more smoothly. When the mold opening distance is sufficient, the oil cylinder 26 can be started, and the oil cylinder 26 drives the driving rod 27 to extend, so that the driving rod 27 pushes the movable mold base 21 upward, so that the movable mold base 21 drives the inclined guide column 1 22 and the inclined guide column 23 to move upward synchronously. Because the inclined guide column 1 22 and the inclined guide column 23 have inclinations, when the movable mold base 21 drives the inclined guide column 1 22 and the inclined guide column 23 to move upward, the inclined slide block 1 24 slides on the outer wall of the inclined guide column 23, and the inclined guide column 1 22 Under the action of the inclined slide block 24, the inclined slide block 25 is synchronously translated in the horizontal direction under the action of the inclined guide column 23, and at the same time, the inner walls of the inclined slide blocks 24 and 25 are slidably connected with the outer wall of the limit block 32, and the limit block 32 guides the inclined slide blocks 24 and 25 so that the inclined slide blocks 24 and 25 will not deviate when sliding, thereby making the outer walls of the inclined slide blocks 24 and 25 no longer contact the storage box 4, thereby simultaneously moving the storage box 4 Demolding on four sides speeds up work efficiency and achieves the effect of demolding on multiple sides at the same time. At the same time, when the movable mold base 21 moves upward, because the driving rod 27 also has an inclination, when the movable mold base 21 moves upward, the guide block 28 slides on the inner wall of the movable mold base 21, and the guide block 28 limits and guides the driving rod 27 to prevent the driving rod 27 from extending too much upward. At the same time, it prevents the driving rod 27 from deviating when extending upward, thereby guiding and limiting the driving rod 27, achieving the effect of guiding and limiting, thereby greatly improving the user experience.
