The driving mechanism 3 includes four cylinders 31. One end of the cylinder 31 is fixedly connected to one end of the slider 27 by bolts. The undercut core pulling mechanism 4 includes a cylinder 41. One end of the cylinder 41 is fixedly connected to the middle part of one end of the slider 27 by bolts.
[0026] When the storage box 5 is injection molded and needs to be demoulded by core pulling, the mold is opened first to completely separate the fixed mold base 1 and the movable mold base 21, and then the movable mold mechanism 2, the driving mechanism 3 and the undercut core pulling mechanism 4 cooperate with each other to complete the overall core pulling and demoulding.
[0027] like Figure 2 , Figure 4 and Figure 5 As shown, the inner wall of the movable mold base 21 is threadedly connected with a bolt 22, the bottom of the bolt 22 is threadedly connected with a core pulling block 23, the outer wall of the core pulling block 23 is plugged into the inner wall of the storage box 5, the inner wall of the core pulling block 23 is slidably connected with a slide rail 231, and the outer wall of the slide rail 231 is clamped with the inner wall of the storage box 5.
[0028] The movable mold base 21 moves upward, driving the bolt 22 to move synchronously, and the bolt 22 drives the core pulling block 23 to move synchronously, so that the outer wall of the core pulling block 23 slides upward on the outer wall of the storage box 5 and the slide rail 231.
[0029] like Figure 2 , Figure 4 and Figure 5 As shown, the inner walls of the front and rear parts of the movable mold base 21 are movably sleeved with an inclined guide column 24, the outer wall of the inclined guide column 24 is movably sleeved with a slider 26, the outer wall of the slider 26 is slidably connected to the inner walls of the fixed mold base 1 and the movable mold base 21, the outer wall of the slider 26 overlaps the outside of the storage box 5, the top of the slider 26 is fixedly connected with a guide block 261 by bolts, the outer wall of the guide block 261 is slidably connected to the inner wall of the slide rail 231, the inner walls of the left and right parts of the movable mold base 21 are movably sleeved with an inclined guide column 25, the outer wall of the inclined guide column 25 is movably sleeved with the inner wall of the slider 27, the outer wall of the slider 27 is slidably connected to the inner wall of the movable mold base 21 and the fixed mold base 1, the top of the slider 27 is fixedly connected with a guide block 271 by bolts, and the outer wall of the guide block 271 is plugged into the inner wall of the slide rail 231.
[0030] When the movable mold base 21 moves upward, the inclined guide column 1 24 and the inclined guide column 25 are driven to move upward. Since the inclined guide column 1 24 and the inclined guide column 25 have a certain inclination, when the inclined guide column 1 24 and the inclined guide column 25 move upward, the slider 1 26 and the slider 2 27 are translated in the horizontal direction, thereby driving the guide block 1 261 and the guide block 271 to move synchronously, so that the guide block 1 261 and the guide block 271 slide on the inner wall of the slide rail 231, and the guide block 1 261 and the guide block 271 are guided by the slide rail 231, so that the guide block 1 261 and the guide block 271 slide more smoothly without deviation, thereby making the outer wall of the slider 1 26 and the slider 2 27 no longer contact the outer wall of the storage box 5.
[0031] like Figure 2 , Figure 3 As shown, the output end of the oil cylinder 31 is fixedly connected to a limit block 32, the outer wall of the limit block 32 is slidably connected to a fixed block 33, and the top end of the fixed block 33 is fixedly connected to the bottom end of the movable mold base 21 by bolts.
[0032] By starting the oil cylinder 1 31 to drive the limit block 32 to move upward, the limit block 32 drives the movable mold base 21 to move upward synchronously, thereby causing the slider 27 to translate in the horizontal direction. At the same time, the slider 27 drives the oil cylinder 1 31 to move synchronously, thereby causing the outer wall of the limit block 32 to slide on the outer wall of the fixed block 33.
[0033] like Figure 2 , Figure 5 and Figure 6As shown, the output end of the oil cylinder 41 is fixedly connected to a driving rod 42, the outer wall of the driving rod 42 is slidably connected to the bottom of the slider 27, the inner wall of the driving rod 42 is clamped with an active slider 43, the outer wall of the active slider 43 is slidably connected to the bottom of the slider 27, the top of the active slider 43 is slidably connected to a demoulding slider 44, the outer wall of the demoulding slider 44 is plugged into the bottom of the slider 27, and the outer walls of the active slider 43 and the demoulding slider 44 are plugged into the bottom of the storage box 5.
[0034] By starting the oil cylinder 41, the driving rod 42 is driven to contract, so that the driving rod 42 drives the active slider 43 to move synchronously. Since the connection between the active slider 43 and the demoulding slider 44 is a slope, when the active slider 43 moves following the driving rod 42, the demoulding slider 44 moves downward, so that the outer wall of the demoulding slider 44 no longer contacts the undercut of the outer wall of the storage box 5, thereby completing the core pulling at the undercut of the storage box 5.
[0035] The working principle of the utility model is as follows: when the injection molding of the storage box 5 is completed and the core pulling and demolding is required, the mold is opened first, and the fixed mold base 1 and the movable mold base 21 are completely separated, and the movable mold base 21 drives the bolt 22 to move synchronously, and the bolt 22 drives the core pulling block 23 to move synchronously, and at the same time, the movable mold base 21 drives the inclined guide column 1 24 and the inclined guide column 25 to move synchronously, and the inclined guide column 1 24 and the inclined guide column 25 respectively drive the slider 1 26 and the slider 2 27 to move upward, so that the bottom of the slider 1 26 and the slider 2 27 no longer contact the inner wall of the fixed mold base 1, thereby driving the storage box 5 to move upward synchronously, so that the bottom of the storage box 5 no longer contacts the top of the connecting block 12 The plug-in is connected, thereby completing the mold opening, and then the core pulling and demoulding can be started, and the oil cylinder 1 31 and the oil cylinder 2 41 are started. The oil cylinder 1 31 drives the limit block 32 upward, so that the limit block 32 drives the movable mold base 21 to move upward synchronously, and the movable mold base 21 drives the bolt 22 to move upward synchronously, so that the bolt 22 drives the core pulling block 23 to move synchronously, and the outer wall of the core pulling block 23 slides upward on the outer wall of the storage box 5 and the slide rail 231. At the same time, the movable mold base 21 drives the inclined guide column 1 24 and the inclined guide column 25 to move upward. Because the inclined guide column 1 24 and the inclined guide column 25 have a certain inclination, when the inclined guide column 1 24 and the inclined guide column 25 move upward, the slider 1 26 The slide block 27 is horizontally translated with the slide block 27, thereby driving the guide block 1 261 and the guide block 2 271 to move synchronously, so that the guide block 1 261 and the guide block 2 271 slide on the inner wall of the slide rail 231, and the slide rail 231 guides the guide block 1 261 and the guide block 2 271, so that the guide block 1 261 and the guide block 2 271 slide more smoothly without deviation, thereby making the outer wall of the slide block 1 26 and the slide block 2 27 no longer contact the outer wall of the storage box 5, and at the same time, the slide block 27 drives the oil cylinder 1 31 to move synchronously, so that the outer wall of the limit block 32 slides on the outer wall of the fixed block 33, and at the same time, the slide block 27 drives the oil cylinder 2 41 The mold release mechanism 42 is a kind of sliding block 43 which is used for the demoulding of the molded product.
