[0025] 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.
[0026] like Figure 1-Figure 5 As shown, a two-way demoulding mechanism of a storage box injection mold comprises a fixed mold base 1, the top of the fixed mold base 1 is in a rectangular array and movably sleeved with four guide pillars 11, the outer wall of the guide pillar 11 is movably sleeved with a guide sleeve 12, the top of the fixed mold base 1 is fixedly connected with a fixed block 13 by bolts, the bottom end of the fixed block 13 overlaps with one end of the guide sleeve 12, the top of the guide pillar 11 is movably sleeved with a movable mold mechanism 2, one end of the movable mold mechanism 2 is fixedly connected with a driving mechanism 3 by bolts, and the movable mold mechanism 2 is movably sleeved with a driving mechanism 3 by bolts. The mold mechanism 2 includes a movable mold base 21 and two outer slide blocks 24. The inner wall of the movable mold base 21 is movably connected to the top of the guide sleeve 12. The outer wall of the outer slide block 24 is slidably connected to the inner wall of the fixed mold base 1 and the movable mold base 21. The bottom of the movable mold base 21 is fixedly connected to a fixed block 211 by bolts. One end of the fixed block 211 overlaps one end of the guide sleeve 12. The driving mechanism 3 includes an oil cylinder 31. The top of the oil cylinder 31 is fixedly connected to one end of the outer slide block 24 by bolts.
[0027] The fixed mold base 1 and the movable mold base 21 are completely separated by opening the mold, and then the driving mechanism 3 drives the movable mold mechanism 2 to complete the demoulding work.
[0028] like Figure 2 , Figure 3 , Figure 7 As shown, the front and rear positions of the bottom of the movable mold base 21 are movably connected with an inclined guide column 22, the outer wall of the inclined guide column 22 is movably connected with the inner wall of the outer sliding block 24, the inner wall of the outer sliding block 24 is slidably connected with a guide rod 29, the inner wall of the guide rod 29 is slidably connected with a guide block 291, and one end of the guide block 291 is fixedly connected to one end of the outer sliding block 24.
[0029] When the movable mold base 21 moves upward, it drives the inclined guide column 22 to move synchronously. Since the inclined guide column 22 has a certain inclination, when the inclined guide column 22 moves upward, the outer slider 24 slides synchronously in the horizontal direction. When sliding, the outer slider 24 drives the guide block 291 to slide synchronously on the inner wall of the guide rod 29. The guide block 291 and the guide rod 29 limit the outer slider 24 so that the outer slider 24 will not deviate when sliding.
[0030] like Figure 2 , Figure 5 ,and Figure 8 As shown, the inner wall of the movable mold base 21 is threadedly connected with a bolt 26, the bottom of the bolt 26 is threadedly connected with an inner mold core 27, the outer wall of the inner mold core 27 is slidably connected with an inner slider 28, the outer wall of the inner slider 28 is clamped with a storage box 4, and the outer wall of the storage box 4 overlaps the outer wall of the outer slider 24.
[0031] When the movable mold base 21 moves upward, the bolt 26 and the inner mold core 27 are driven to move upward synchronously, so that the outer wall of the inner mold core 27 slides upward on the inner wall of the inner slider 28, thereby allowing the inner slider 28 to slide toward the inner wall of the storage box 4, and then the storage box 4 can be removed, achieving the demoulding effect.
[0032] like Figure 2 , Figure 4 , Figure 5 As shown, the left and right parts of the top of the outer slider 24 are fixedly connected to the limit block 241, the outer wall of the limit block 241 is slidably connected to the top of the inner slider 28, and the outer wall of the limit block 241 is plugged into the inner wall of the movable mold base 21.
[0033] When the outer slider 24 slides, it drives the limit block 241 to slide on the inner wall of the inner slider 28, and the inner slider 28 guides the limit block 241, so that the limit block 241 slides more smoothly without deviation.
[0034] like Figure 2 , Figure 7 As shown, the left and right parts of the bottom 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 outer slider 25, the outer wall of the outer slider 25 is plugged into the inner wall of the movable mold base 21 and the fixed mold base 1, the outer wall of the outer slider 25 overlaps the outer wall of the outer slider 1 24, the outer wall of the outer slider 25 overlaps the outer wall of the storage box 4, the inner wall of the outer slider 25 is slidably connected to the outer wall of the guide rod 29, and one end of the outer slider 25 is fixedly connected to one end of the guide block 291.
[0035] When the movable mold base 21 moves upward, it drives the inclined guide column 23 to move synchronously. Since the inclined guide column 23 has a certain inclination, when the inclined guide column 23 moves upward, the outer sliding block 25 slides synchronously in the horizontal direction. When sliding, the outer sliding block 25 drives the guide block 291 to slide synchronously on the inner wall of the guide rod 29. The guide block 291 and the guide rod 29 limit the outer sliding block 25 so that the outer sliding block 25 will not deviate when sliding.
[0036] like Figure 2 , Figure 4 As shown, the output end of the oil cylinder 31 is fixedly connected with a driving rod 32, the inner wall of the driving rod 32 is slidably connected with a connecting block 33, and the top of the connecting block 33 is fixedly connected to the bottom of the movable mold base 21 by bolts.
[0037] Start the oil cylinder 31, and the oil cylinder 31 drives the driving rod 32 to move upward, so that the driving rod 32 drives the movable mold base 21 to move upward synchronously. Because the oil cylinder 31 has a certain inclination, when the driving rod 32 drives the movable mold base 21 to move upward, the inner wall of the driving rod 32 slides on the outer wall of the connecting block 33.
[0038] The working principle of the utility model is as follows: during operation, after the injection molding is completed, the fixed mold base 1 and the movable mold base 21 are separated as a whole through the power of the injection molding machine, so that the outer walls of the outer slide block 1 24 and the outer slide block 25 are no longer in contact with the inner wall of the fixed mold base 1, and at the same time, the outer wall of the storage box 4 is no longer in contact with the inner wall of the fixed mold base 1, and under the guidance of the guide column 11, the movable mold base 21 and the fixed mold base 1 are separated as a whole more smoothly and will not deviate, and then the oil cylinder 31 is started, and the oil cylinder 31 drives the driving rod 32 to move upward, so that the driving rod 32 drives the movable mold base 21 to move upward synchronously. Because the oil cylinder 31 has a certain inclination, when the driving rod 32 drives the movable mold base 21 to move upward, the inner wall of the driving rod 32 slides on the outer wall of the connecting block 33, and when the movable mold base 21 moves upward, it drives the inclined guide column 1 22 and the inclined guide column 23 to move synchronously. Because the inclined guide column 1 22 and the inclined guide column 23 have a certain inclination, when the inclined guide column 1 22 When the outer slider 1 24 and the outer slider 2 25 move upward with the inclined guide column 23, the outer slider 1 24 and the outer slider 2 25 slide synchronously in the horizontal direction. When sliding, the outer slider 1 24 and the outer slider 2 25 drive the guide block 291 to slide synchronously on the inner wall of the guide rod 29, and the guide block 291 and the guide rod 29 limit the outer slider 1 24 and the outer slider 2 25, so that the outer slider 1 24 and the outer slider 2 25 will not deviate when sliding. At the same time, the outer slider 1 24 drives the limit block 241 to slide on the inner wall of the inner slider 28, and the limit block 241 is guided by the inner slider 28, so that the limit block 241 slides more smoothly and will not deviate. At the same time, the movable mold seat 21 drives the bolt 26 and the inner mold core 27 to move upward synchronously, so that the outer wall of the inner mold core 27 slides upward on the inner wall of the inner slider 28, thereby allowing the inner slider 28 to slide toward each other on the inner wall of the storage box 4, and then the storage box 4 can be removed, which has a demoulding effect, thereby greatly improving the user experience.
