A first rotating cylinder 40 is arranged on the outer end of the first mounting rod 39. A second mounting rod 41 with a length less than the first mounting rod 39 is arranged on the right side of the front end of the upper mold 34 along its front-to-back direction. A second rotating cylinder 42 is arranged at the outer end of the mounting rod 41; a mounting seat 43 is fixedly arranged at the middle of the front end of the lower mold 34, and a third rotating cylinder 45 is arranged on the mounting seat 43 through a third mounting rod 44, and the third mounting rod 44 is arranged along the front and rear direction of the mold; a clamping mechanism is arranged above the mounting seat 43, and the clamping mechanism includes a driving rod 51 and a fourth rotating cylinder 52 arranged at the outer end of the driving rod 51; a first connecting rod 6 is arranged at the front end of the conveying chain plate 2 in a one-to-one correspondence with the mold, and a bearing 7 is arranged at the outer end of the first connecting rod;

[0037] 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;

[0038] 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; the third guide rod is arranged on the left side of the second guide rod 19, including a mold opening section 21 and a transition section 22, and 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.

[0039] The automatic mold opening mechanism of the railway elastic pad mold provided by the utility model has a clever structural design. By setting the first guide rod 17, the second guide rod 19 and the third guide rod, and cooperating with the lever mechanism, the first rotating cylinder 40 and the fourth rotating cylinder 52 in the pressing mechanism, the leveling, pressing release and mold opening of the mold are realized. The automation degree is high, the labor cost is reduced, and the production efficiency is greatly improved.

[0040] As Figure 7 shown, in this embodiment, there is an included angle between the turning block 11 and the lever 12, and the turning block 11 is located on the left side of the lever 12. When the bearing 7 moves from right to left along the conveyor chain plate 2 and presses the turning block 11, the turning block 11 drives the lever 12 to拨动 the first rotating cylinder 40 of the upper mold 37 of the right mold, causing the mold to tilt 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.

[0041] As Figure 8 and Fig. 9 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 the lower mold 34 is always in a horizontal state during the opening process of the upper mold 37.

[0042] As Figure 2 and Figure 8 shown, an installation strip 53 is further provided at the front end of the frame 1. The first guide wheels 54 corresponding to the upper surface of the conveyor chain plate 2 and the 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.

[0043] A first hinge seat 3 is arranged on the conveyor chain plate 2, and 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. Third hinge seats 36 and fourth hinge seats 38 corresponding to each other are respectively arranged at the rear ends of the lower mold 34 and the upper mold 37.

[0044] As Fig.10 and Fig.11As shown, the clamping mechanism includes a bracket 46 fixed above the mounting seat 43, the bracket 46 is hinged with a first connecting frame 47 on the outer side, and is hinged with a third connecting frame 50 on the inner side, the hinge position of the first connecting frame 47 and the bracket 46 is higher than the hinge 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, and the second connecting frame 49 is located on the outer side of the first connecting frame 47; the outer end of the first connecting frame 47 is provided with a clamping rod 48 corresponding to the upper surface of the upper mold 37, and the outer end of the third connecting frame 50 is provided with the driving rod 51.

[0045] As a further optimization, the automatic mold opening mechanism of the railway elastic pad mold also includes a limit rod 24 arranged in parallel on the outside of the transition section 22, and the left and right ends of the limit rod 24 are bent toward the front end of the frame 1. When the first rotating drum 40 moves along the transition section 22, it is located between the transition section 22 and the limit rod 24, and the upper mold 37 is in a vertical state. The limit rod 24 is set to prevent the upper mold 37 from flipping to the rear end side of the frame 1, making it difficult to close the mold again.

[0046] As a further optimization, a buffer block 16 is installed on the frame 1 at the right side of the lever 12 through the mounting block 15, and the buffer block 16 is made of rubber.

[0047] In this embodiment, the first guide rod 17 is fixed on the frame 1 through the first mounting frame 18; the second guide rod 19 is fixed on the frame 1 through the second mounting frame 20; the third guide rod and the limit rod 24 are fixed on the frame 1 through the third mounting frame 25.

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

[0049] The third guide rod of the mold further includes a mold closing section 23. The mold opening section 21, the transition section 22 and the mold closing section 23 together constitute the third guide rod. The mold closing section 23 allows the upper mold 37 to gradually close relative to the horizontal lower mold 34 during the movement of the opened mold from right to left.

[0050] 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.

[0051] like Figure 3 and Figure 6As shown, the automatic die-closing mechanism of the die further 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 die 37, so that the die is turned into an inclined state. At this time, the common plane where the axis of the first rotating cylinder 40 and the hinge connecting rod 4 are located is a vertical plane, and the center of gravity of the die is located on the right side of the vertical plane. Under the action of its own gravity, the die is automatically adjusted to a vertical state.

[0052] As a further optimization, the automatic die-closing mechanism of the die further includes a seventh guide rod 32 arranged below the sixth guide rod 31 to guide and support the second rotating cylinder 42.

[0053] As a further optimization, the automatic die-closing mechanism of the die further includes a fifth guide rod 27 that cooperates with the right-side part of the break 29 of the fourth guide rod 26. The fourth guide rod 26 and the fifth guide rod 27 jointly guide the fourth rotating cylinder 52 located between the two.

[0054] As a further optimization, a U-shaped second limiting rod 9 is horizontally arranged along the left-right direction below the fourth guide rod 26 at the front end of the frame 1. The third rotating cylinder 45 is located inside the second limiting rod 9, so that during the process of pressing the upper die 37 by the pressing mechanism, the lower die 34 is always in a horizontal state.

[0055] In this embodiment, the third guide rod is fixed to the frame 1 through a third mounting bracket 25; the right-side part of the break 29 of the fourth guide rod 26 and the fifth guide rod 27 are fixed to the frame 1 through a fourth mounting bracket 28; the left-side part of the break 29 of the fourth guide rod 26 is fixed to the frame 1 through a fifth mounting bracket 30; the sixth guide rod 31 and the seventh guide rod 32 are fixed to the frame 1 through a sixth mounting bracket 33.

[0056] The working processes of the die-opening mechanism and the die-closing mechanism:

[0057] The die is conveyed on the frame 1 from right to left along with the conveyor chain plate 2. Initially, the die is turned to a vertical state with the hinge connecting rod 4 as the axis;

[0058] As the die 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 lever 12 to拨动 the first rotating cylinder 40 of the upper die 37 on the right side of the die, so that the die tilts to the left. The first rotating cylinder 40 is placed on the first guide rod 17 under the action of the gravity of the die. As the die moves from right to left, the first rotating cylinder 40 moves along the first guide rod 17 until the die is in a horizontal state;

[0059] As the die 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 die 37;

[0060] As the mold moves from right to left, the first rotating drum 40 interferes with the mold opening section 21 located below. Under the action of the mold opening section 21, the first rotating drum 40 drives the upper mold 37 to gradually open upward; at the same time, the third rotating drum 45 enters the first limiting rod 8, so that the lower mold 34 is always in a horizontal state during the opening process of the upper mold 37;

[0061] 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;

[0062] 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.

[0063] 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.

[0064] 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.
