[0037] A third guide rod, which is arranged at the upper rear end of the frame 1, supports and guides the first rotating cylinder 40 of the upper mold 37 of the opened rear mold, and the third guide rod includes a transition section 22 and a mold closing section 23, so that the upper mold 37 is gradually closed relative to the horizontal lower mold 34 during the movement of the opened mold from right to left;

[0038] The fourth guide rod 26 is arranged crosswise with the mold closing section 23 to guide the fourth rotating drum 52 in the clamping mechanism so that the clamping rod 48 in the clamping mechanism can clamp the upper surface of the upper mold 37 after mold closing; the fourth guide rod 26 is provided with a break 29 on the left side of the intersection with the mold closing section 23, and the break 29 allows the first rotating drum 40 to pass through.

[0039] like Figure 3 and Figure 6 As shown, the automatic clamping mechanism of the railway elastic pad mold also includes a sixth guide rod 31, which is arranged on the left side of the fourth guide rod 26 to guide the first rotating cylinder 40 of the upper mold 37 so that the mold is flipped to an inclined state. At this time, the common plane where the axis of the first rotating cylinder 40 and the hinge rod 4 are located is a vertical plane, and the center of gravity of the mold is located on the vertical right side of the plane. The mold automatically adjusts to a vertical state under the action of its own gravity.

[0040] The automatic mold closing mechanism for the railway elastic pad mold provided by the utility model has an ingenious structural design. By arranging the third guide rod, the fourth guide rod 26 and the sixth guide rod 31, in cooperation with the first rotating drum 40 and the fourth rotating drum 52 in the clamping mechanism, the mold closing, clamping and vertical flipping are realized, the degree of automation is high, the labor cost is reduced, and the production efficiency is greatly improved.

The fourth guide rod 26 and the fifth guide rod 27 jointly guide the fourth rotating cylinder 52 located in the middle of the two.

[0043] As a further optimization, a U-shaped second limiting rod 9 is horizontally arranged in the front end of the frame 1 below the fourth guide rod 26 along the left-right direction. The third rotating cylinder 45 is located inside the second limiting rod 9, so that during the process of the pressing mechanism pressing the upper mold 37, the lower mold 34 is always in a horizontal state.

[0044] A first hinge seat 3 is arranged on the conveyor chain plate 2. A second hinge seat 35 adapted to the first hinge seat 3 is arranged at the bottom right of the lower mold 34. The first hinge seat 3 and the second hinge seat 35 are hinged together by a hinge connecting rod 4; An adjusting bolt 5 corresponding to the middle position on the left side of the lower mold 34 is arranged on the conveyor chain plate 2 in a height-adjustable manner. Corresponding third hinge seats 36 and fourth hinge seats 38 are respectively arranged at the rear ends of the lower mold 34 and the upper mold 37.

[0045] As Fig.10 and Fig.11 shown, the pressing mechanism includes a bracket 46 fixedly arranged above the mounting seat 43. A first connecting frame 47 is hinged to the outside of the bracket 46, and a third connecting frame 50 is hinged to the inside. The hinged position of the first connecting frame 47 and the bracket 46 is higher than the hinged position of the third connecting frame 50 and the bracket 46. A second connecting frame 49 is hinged between the first connecting frame 47 and the third connecting frame 50. The second connecting frame 49 is located outside the first connecting frame 47; A pressing rod 48 corresponding to the upper surface of the upper mold 37 is arranged at the outer end of the first connecting frame 47, and the driving rod 51 is arranged at the outer end of the third connecting frame 50.

[0046] In this embodiment, the automatic mold-closing mechanism of the railway elastic pad mold further includes limiting rods 24 arranged in parallel on the outside of the transition section 22. The left and right ends of the limiting rods 24 are bent towards the front end of the frame 1. When the first rotating cylinder 40 moves along the transition section 22, it is located between the transition section 22 and the limiting rods 24, and the upper mold 37 is in a vertical state. By arranging the limiting rods 24, it is prevented that the upper mold 37 flips to the rear end side of the frame 1 and it is difficult to perform mold closing again.

[0047] In this embodiment, the third guide rod is fixed to the frame 1 via a third mounting frame 25; the right side portion of the break 29 of the fourth guide rod 26 and the fifth guide rod 27 are fixed to the frame 1 via a fourth mounting frame 28; the left side portion of the break 29 of the fourth guide rod 26 is fixed to the frame 1 via a fifth mounting frame 30; the sixth guide rod 31 and the seventh guide rod 32 are fixed to the frame 1 via a sixth mounting frame 33.

[0048] like Figure 1-Figure 11 As shown, the railway elastic pad mold automatic mold closing mechanism cooperates with the mold automatic mold opening mechanism to complete the mold opening and closing, wherein the mold automatic mold opening mechanism includes the following structure:

[0049] The front end of the conveying chain plate 2 is provided with a first connecting rod 6 corresponding to the mold, and the outer end of the first connecting rod is provided with a bearing 7;

[0050] The lever mechanism comprises a rotating shaft 10 fixedly mounted on the front end of the frame 1, a flip block 11 rotatably mounted on the rotating shaft 10, and a lever 12, wherein the flip block 11 and the lever 12 are fixedly connected together, wherein the lever 12 is located outside the flip block 11, the flip block 11 is arranged corresponding to the bearing 7, a tension spring 14 is arranged between the right side of the lever 12 and the frame 1, and in a free state, the lever 12 is located below the first rotating drum 40 under the action of the tension spring 14;

[0051] The first guide rod 17 is arranged at the front right side of the frame 1 and corresponds to the first rotating drum 40, so that the upright mold is gradually flattened as it moves from right to left; the second guide rod 19 is arranged on the left side of the first guide rod 17 and corresponds to the fourth rotating drum 52 in the clamping mechanism, so that the clamping mechanism is gradually opened as the flattened mold moves from right to left; it also includes a mold opening section 21, and the mold opening section 21, the transition section 22 and the mold closing section 23 together constitute the third guide rod. The mold opening section 21 is arranged corresponding to the first rotating drum 40, so that the upper mold 37 is gradually opened relative to the lower mold 34 during the movement of the flattened mold from right to left.

[0052] like Figure 7 As shown, in this embodiment, there is an angle between the flip block 11 and the lever 12, and the flip block 11 is located on the left side of the lever 12. When the bearing 7 moves from right to left with the conveying chain plate 2 to squeeze the flip block 11, the flip block 11 drives the lever 12 to move the first rotating cylinder 40 of the upper mold 37 on the right side of the mold, so that the mold tilts to the left. As the mold moves from right to left, under the action of gravity, the first rotating cylinder 40 moves along the first guide rod 17 until the mold is in a horizontal state.

[0053] like Figure 8 and Fig. 9As shown, a U-shaped first limiting rod 8 is horizontally arranged along the left-right direction below the third guide rod at the front end of the frame 1. The third rotating cylinder 45 is located inside the first limiting rod 8, so that during the opening process of the upper mold 37, the lower mold 34 is always in a horizontal state.

[0054] As Figure 2 and Figure 8 shown, an installation strip 53 is further arranged at the front end of the frame 1. First guide wheels 54 corresponding to the upper surface of the conveyor chain plate 2 and second guide wheels 55 corresponding to the front end surface of the conveyor chain plate 2 are uniformly installed along the length on the installation strip 53.

[0055] As a further optimization, a buffer block 16 is installed on the frame 1 on the right side of the toggle lever 12 through a mounting block 15. The buffer block 16 is made of rubber material.

[0056] In this embodiment, the first guide rod 17 is fixedly arranged on the frame 1 through a first mounting bracket 18; the second guide rod 19 is fixedly arranged on the frame 1 through a second mounting bracket 20; the third guide rod and the limiting rod 24 are fixedly arranged on the frame 1 through a third mounting bracket 25.

[0057] The working processes of the mold opening mechanism and the mold closing mechanism:

[0058] The mold is conveyed on the frame 1 from right to left along with the conveyor chain plate 2. Initially, the mold is in a vertical state with the hinge connecting rod 4 as the axis;

[0059] As the mold moves to the left, the bearing 7 on the conveyor chain plate 2 presses on the turning block 11. The turning block 11 drives the toggle lever 12 to拨动 the first rotating cylinder 40 of the upper mold 37 on the right side of the mold, causing the mold to tilt to the left. The first rotating cylinder 40 rests on the first guide rod 17 under the action of the gravity of the mold. As the mold moves from right to left, the first rotating cylinder 40 moves along the first guide rod 17 until the mold is in a horizontal state;

[0060] As the mold moves from right to left, the second guide rod 19 interferes with the fourth rotating cylinder 52. The fourth rotating cylinder 52 is gradually opened outwards under the action of the second guide rod 19, and the pressing mechanism releases the upper mold 37;

[0061] As the mold moves from right to left, the first rotating cylinder 40 interferes with the mold opening section 21 located below. Under the action of the mold opening section 21, the first rotating cylinder 40 drives the upper mold 37 to gradually open upwards; at the same time, the third rotating cylinder 45 enters the first limiting rod 8, so that during the opening process of the upper mold 37, the lower mold 34 is always in a horizontal state;

[0062] After the first rotating drum 40 moves along the transition section 22 for a distance, it performs preliminary mold closing under the action of the left end of the limiting rod 24, so that the upper mold 37 is no longer in a vertical state, but tilted toward the front end of the frame 1. Under the action of its own gravity, the first rotating drum 40 rests on the mold closing section 23, and gradually buckles with the lower mold 34 as the mold moves from right to left; during the process of the first rotating drum 40 moving down along the mold closing section 23, it passes through the fracture 29;

[0063] When the upper mold 37 is closed downward, the fourth guide rod 26 interferes with the outer side of the fourth rotating cylinder 52 in the clamping mechanism. As the mold moves from right to left, the fourth rotating cylinder 52 is gradually lifted upward under the action of the fourth guide rod 26, driving the clamping rod 48 to clamp the top of the upper mold 37. At the same time, the third rotating cylinder 45 is located inside the second limiting rod 9, so that the clamping mechanism is in the process of clamping the upper mold 37, and the lower mold 34 is always in a horizontal state.

[0064] As the mold moves from right to left, the first rotating cylinder 40 interferes with the right end of the sixth guide rod 31 located below it. As the mold continues to move, the first rotating cylinder 40 is lifted upward by the sixth guide rod 31, driving the mold to flip to an inclined state until the common plane of the first rotating cylinder 40 and the axis of the hinge rod 4 is a vertical plane; as the mold continues to move, the first rotating cylinder 40 separates from the sixth guide rod 31. At this time, the center of gravity of the mold is biased to the right, and the mold automatically flips to a vertical state under the action of its own gravity.

[0065] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
