Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, the linkage mechanism for driving the cam through the grooved pulley 13 is used for linking the mold opening and closing frame and the bottom mold frame 5.
The mold opening and closing mold frame comprises a left mold frame 3 and a right mold frame 4 which can rotate around a first shaft 1 and are arranged on the rack 2, a bottom mold frame 5 is arranged on a bottom mold support 6 in a lifting mode, and the bottom mold support 6 is fixedly connected to the rack 2. In this embodiment, a guiding sleeve 21 is fixedly disposed on the bottom die support 6, a guiding shaft 22 is fixedly connected below the bottom die frame 5, and the guiding shaft 22 can be vertically lifted and lowered to penetrate through the guiding sleeve 21.
The link gear for driving the cam through the grooved pulley 13 further comprises a second shaft 7 which can rotate around the axis line direction of the link gear, is arranged on the frame 2, a first swing arm 8, one end of which is fixedly arranged on the second shaft 7 and is used for driving the second shaft 7 to rotate, a first driving mechanism, and a cam mechanism, wherein the first driving mechanism is arranged between the second shaft 7 and the mold opening and closing frame and is used for driving the left mold frame 3 and the right mold frame 4 to be matched with each other when the second shaft 7 rotates and is used for rotatably opening or rotatably closing the mold, and the cam mechanism is used for. In the present embodiment, the cam mechanism includes a third roller 9 fixedly connected below the first swing arm 8, and a cam guide (not shown in the figure) for driving the first swing arm 8 to swing through the third roller 9. The first swing arm 8 is driven to swing around the axis line direction of the second shaft 7 by the rolling of the third roller 9 on the cam guide.
In this embodiment, the first driving mechanism includes a mold opening and closing swing arm 17 having one end fixed to the second shaft 7, a first connecting rod 18 having two ends respectively hinged to the other end of the mold opening and closing swing arm 17 and the left mold frame 3, and a second connecting rod 19 having two ends respectively hinged to the other end of the mold opening and closing swing arm 17 and the right mold frame 4. The first shaft 1 and the second shaft 7 each extend in a vertical direction. When the mold is opened, the first swing arm 8 drives the second shaft 7 to rotate in the positive direction, so that the mold opening and closing swing arm 17 swings in the positive direction, and the left mold frame 3 and the right mold frame 4 are respectively driven to rotate for mold opening through the first connecting rod 18 and the second connecting rod 19; during mold closing, the first swing arm 8 drives the second shaft 7 to rotate reversely, so that the mold opening and closing swing arm 17 swings reversely, and the left mold frame 3 and the right mold frame 4 are driven to rotate and close the mold through the first connecting rod 18 and the second connecting rod 19 respectively.
The linkage mechanism for driving the cam through the grooved pulley 13 further comprises a cam 10 which can be arranged on the bottom die support 6 in a reciprocating sliding manner along a linear direction and is provided with a curved groove 11, a first roller 12 which can be arranged on the bottom die mold frame 5 in a rotating manner around the axial lead direction of the first roller and is arranged in the curved groove 11 in a penetrating manner, the grooved pulley 13 of which one end is fixedly arranged on the second shaft 7 and is provided with a linear groove 14, and a second roller 15 which is arranged on the cam 10 in a rotating manner around the axial lead direction of the second roller and is arranged in the linear groove 14 in a penetrating manner; the oscillation plane of the sheave 13 is perpendicular to the sliding plane of the cam 10.
In the embodiment, the cam 10 is located below the bottom die carrier 5 and in a vertical plane, the sliding direction of the cam 10 is parallel to a horizontal plane, and the cam 10 slides in a direction close to or far away from the second shaft 7; the sheave 13 is located in a horizontal plane. The axis of the first roller 12 extends in the horizontal direction, and the axis of the second roller 15 extends in the vertical direction. The sheave 13 is located between the opening and closing swing arm 17 and the first swing arm 8 in the vertical direction, and the second roller 15 penetrates upward into the linear groove 14.
The axis of the second shaft 7 deviates from the sliding direction of the cam 10, that is, the axis of the second shaft 7 deviates from the extension line of the cam 10 along the sliding direction, and the two do not intersect at a certain point, so that the transmission between the grooved wheel 13 and the cam 10 is more stable and easier to realize. Specifically, in the mold opening and closing process, the length direction of the linear groove 14 and the sliding direction of the cam 10 are always kept at an angle, so that the two are prevented from being parallel to each other.
The wedge-shaped snap rings arranged in the left mold frame 3 and the right mold frame 4 need to completely enter the wedge-shaped ring groove of the bottom mold frame 5 during mold closing, and need to completely separate from the wedge-shaped ring groove of the bottom mold frame 5 during mold opening. Therefore, the movement of the bottom die frame 5 must be stopped when the opening and closing die frame is in the opening initial stage and near the closing stage. Through the curve groove 11 of the adjusting cam 10, the open-close die carrier can be ensured to be in the opening initial stage and close to the closing stage, namely when the bottom die carrier 5 is located at the highest point, the bottom die carrier 5 can be temporarily in the self-locking state, and at the moment, even if the cam 10 continues to slide, the bottom die carrier 5 cannot be driven to do lifting movement through the first roller 12. Because the grooved pulley 13 and the cam 10 are both planar motion structures, the design of the grooved pulley and the cam is simple, a redundant section can be easily reserved at one end of the curved groove 11, and when the first roller 12 enters the redundant section, the bottom die mold frame 5 is in a self-locking state and is not influenced by linkage.
When the first swing arm 8 swings in the forward direction, the second shaft 7 is driven to rotate in the forward direction:
the die opening and closing swing arm 17 is enabled to swing in the positive direction, and the left die frame 3 and the right die frame 4 are respectively driven to rotate and open the die through the first connecting rod 18 and the second connecting rod 19;
the grooved wheel 13 is made to swing in the positive direction, and the bottom die frame 5 is driven to descend by the cam 10.
When the first swing arm 8 swings reversely, the second shaft 7 is driven to rotate reversely:
the die opening and closing swing arm 17 swings reversely, and the left die frame 3 and the right die frame 4 are driven to rotate and close the dies through the first connecting rod 18 and the second connecting rod 19 respectively;
the grooved pulley 13 is swung in the reverse direction, and the cam 10 drives the bottom die frame 5 to ascend.
The linkage mechanism for driving the cam 10 through the grooved wheel 13 further comprises a slide block 20 fixedly arranged on the bottom die support 6, a linear guide rail 16 fixedly arranged at the lower part of the cam 10 and used for sliding on the slide block 20 in a matched manner, and a curved groove 11 is formed at the upper part of the cam 10.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
