The axial lead of the first shaft 1 is distributed along the vertical direction, and the bottom die carrier is arranged below the opening and closing die carrier in a lifting mode.
The linkage mechanism comprises a second shaft 5 which rotates around the direction of the axis line of the linkage mechanism and is arranged on a rack 2, a first driving mechanism 6 which is arranged between the second shaft 5 and a mold opening and closing frame and is used for driving a first mold frame 3 and a second mold frame 4 to be matched with each other when the second shaft 5 rotates and rotating to open or close the mold, a second driving mechanism 7 which is arranged between the second shaft 5 and a bottom mold frame and is used for driving the bottom mold frame to lift when the second shaft 5 rotates, and a third driving mechanism 8 which is arranged on the rack 2 and is used for driving the second shaft 5 to rotate. The axis of the second shaft 5 is distributed along the vertical direction. When the second shaft 5 rotates clockwise (see the rotation direction of the second shaft with reference to the viewing angle of fig. 2), the first driving mechanism 6 drives the first mold frame 3 and the second mold frame 4 to open the mold in a mutually matched manner, and simultaneously the second driving mechanism 7 drives the bottom mold frame to descend; when the second shaft 5 rotates anticlockwise, the first driving mechanism 6 drives the first die carrier 3 and the second die carrier 4 to be matched with each other for die assembly, and meanwhile, the second driving mechanism 7 drives the bottom die carrier to ascend. The first driving mechanism and the second driving mechanism are synchronously controlled through the second shaft, so that the component structure is simplified, the processing cost is reduced, the debugging of the equipment is easier, and the installation time of the equipment is reduced.
The first driving mechanism 6 comprises a first connecting rod 61, one end of which is fixedly sleeved on the second shaft 5, a second connecting rod 62, one end of which is hinged on the first die carrier 3 and is used for driving the first die carrier 3 to rotate around the first shaft 1, and a third connecting rod 63, one end of which is hinged on the second die carrier 4 and is used for driving the second die carrier 4 to rotate around the first shaft 1. The other end of the second link 62 is hinged to the other end of the first link 61, and the other end of the third link 63 is also hinged to the other end of the first link 61. The first link 61, the second link 62, and the third link 63 are all distributed in the horizontal direction.
In the present embodiment, the other end of the second link 62 is hinged to the other end of the first link 61 through a third shaft 64, and the other end of the third link 63 is also hinged to the other end of the first link 61 through the third shaft 64. One end of the second connecting rod 62 is hinged to the first die carrier 3 through a fourth shaft 65, one end of the third connecting rod 63 is hinged to the second die carrier 4 through a fifth shaft 66, and the fourth shaft 65 and the fifth shaft 66 pass through the first shaft 1 in an axisymmetric distribution center line. Two second connecting rods 62 are arranged, and the two second connecting rods 62 are vertically and parallelly distributed between the third shaft 64 and the fourth shaft 65; the number of the third connecting rods 63 is also two, and the two third connecting rods 63 are distributed between the third shaft 64 and the fifth shaft 66 in an up-down parallel mode. The third shaft 64, the fourth shaft 65 and the fifth shaft 66 are all distributed along the vertical direction.
The second shaft 5 rotates around the axis direction of the second shaft, so that the first connecting rod 61 is driven to rotate along with the second shaft 5. One end of the first connecting rod 61 is fixedly sleeved on the second shaft 5, and when the other end of the first connecting rod 61 rotates away from the first shaft 1 (namely the second shaft 5 rotates clockwise), the first mold frame 3 and the second mold frame 4 are driven to rotate and open the mold through the second connecting rod 62 and the third connecting rod 63; when the other end of the first connecting rod 61 rotates to approach the first shaft 1 (i.e. when the second shaft 5 rotates counterclockwise), the second connecting rod 62 and the third connecting rod 63 drive the first mold frame 3 and the second mold frame 4 to rotate and mold.
The second driving mechanism 7 includes a first swing arm 71 having one end fixed and sleeved on the second shaft 5, a lifting mechanism disposed at the other end of the first swing arm 71 and configured to move up and down along with the swing of the first swing arm 71, and a bottom mold fixing block 72 disposed above the lifting mechanism and configured to mount a bottom mold frame. The first swing arms 71 are distributed in the horizontal direction.
The lifting mechanism comprises a connecting block 73 fixedly connected to the frame 2, a guide post 74 vertically arranged in the connecting block 73 in a penetrating manner, and a first cam 75 fixedly connected to the lower end of the guide post 74, wherein the first cam 75 is provided with a cam groove 76 which is distributed in an up-and-down inclined manner along the swinging direction of the first swing arm 71, and the other end of the first swing arm 71 is provided with a bearing 77 which is slidably arranged in the cam groove 76. The guide posts 74 are distributed in the vertical direction. The bottom die fixing block 72 is disposed at the upper end of the guide post 74. By the swing of the first swing arm 71, the first cam 75 is driven by the bearing 77 to move up and down, and the guide post 74 is driven to move up and down in the connecting block 73.
The second shaft 5 rotates around the axis direction of the second shaft 5, so that the first swing arm 71 is driven to swing along with the second shaft 5. When the first swing arm 71 rotates clockwise (the rotation direction of the first swing arm 71 is observed along the top view in fig. 1), the first cam 75 moves downward to drive the bottom die mold frame to descend; when the first swing arm 71 rotates counterclockwise, the first cam 75 moves upward to drive the bottom die carrier to ascend. That is, the cam grooves 76 are gradually inclined upward in the direction in which the first swing arm 71 rotates clockwise.
The third driving mechanism 8 includes a second swing arm 81 having one end fixed and sleeved on the second shaft 5, and a second cam disposed at the other end of the second swing arm 81 and used for driving the second swing arm 81 to swing so as to drive the second shaft 5 to rotate. The second swing arms 81 are distributed in the horizontal direction.
The following specifically explains the working process of this embodiment:
when the mold is opened, the third driving mechanism 8 drives the second shaft 5 to rotate clockwise around the axis line direction of the second driving mechanism through the second swing arm 81, drives the first connecting rod 61 to rotate along with the second shaft 5, so that one end of the first connecting rod 61, which is provided with the third shaft 64, rotates away from the first shaft 1, drives the first mold frame 3 and the second mold frame 4 to rotate for mold opening through the second connecting rod 62 and the third connecting rod 63, and at the moment, as the first swing arm 71 rotates clockwise under the drive of the second shaft 5, the first cam 75 moves downwards, and drives the bottom mold frame to descend synchronously;
during die assembly, the third driving mechanism 8 drives the second shaft 5 to rotate anticlockwise around the axis line direction of the second driving mechanism through the second swing arm 81, drives the first connecting rod 61 to rotate along with the second shaft 5, enables one end, provided with the third shaft 64, of the first connecting rod 61 to rotate to be close to the first shaft 1, drives the first die carrier 3 and the second die carrier 4 to rotate through the second connecting rod 62 and the third connecting rod 63 to perform die assembly, and at the moment, as the first swing arm 71 rotates anticlockwise under the driving of the second shaft 5, the first cam 75 moves upwards, and drives the bottom die carrier to ascend synchronously.
