Description

Technical Field

[0001] The utility model belongs to the technical field of rail insulating splints, and particularly relates to a preparation tooling for insulating splints. Background Technique

[0002] The rail insulating joint is located at the rail joint at both ends of the track block. It has two functions. One is to divide the track circuit section and separate adjacent track circuits. The other is to firmly connect two rails together through splints and bolts, bearing the vertical force, lateral force acting on the joint when the train passes, and the temperature force generated during thermal expansion and contraction. Therefore, it must have sufficient mechanical and mechanical properties. Due to the laying and development of rails across intervals and seamless tracks including turnouts, bonded rail insulating joints are widely used in China. Practice has proved that the bonded rail insulating joint not only has good insulation performance, but also has excellent mechanical and mechanical properties. It does not require maintenance and replacement and can reach the same service life as the rail. Without a doubt, its social and economic benefits will be reflected through long-term practical applications.

[0003] The insulating splint of the bonded insulating joint generally adopts a "sandwich" structure, with an insulating layer sandwiched between two steel plates. For example, a rail seamless line insulating joint disclosed in the Chinese patent authorization publication number CN202298378U. The insulating fishplate adopted in this scheme is composed of a splint, an insulating layer board and a protection board. The insulating layer board is composed of four layers of PK4080 epoxy film and three layers of alkali-free fiberglass cloth stacked at intervals. Since the insulating fishplate has an arc surface structure, it is difficult to position. Moreover, the insulating layer board of the insulating fishplate needs to be used in a high-temperature environment (about 250°C - 300°C). This material is relatively soft and presents a semi-solid state at high temperatures. It is neither easy to lock nor easy to produce glue overflow phenomenon. Therefore, in order to solve the above problems, the Chinese patent authorization publication number CN202607885U discloses a special mold for insulating splints. However, when using the special mold of this scheme to produce insulating fishplates, the insulating layer board will stick to the inner wall of the mold when glue overflows, and it is not easy to remove the insulating fishplate. Manually removing it will result in high labor intensity and affect the quality of the insulating fishplate, thus bringing the problem of low production efficiency.

[0004] Therefore, it is necessary to provide a preparation tooling for insulating splints to solve the above technical problems. Content of the Utility Model

[0032] Please refer to Figures 1-5 In this embodiment, a preparation tooling for an insulating splint is provided. The preparation tooling 100 for the insulating splint includes a frame 1, a mold base 2 that is movably arranged left and right on the frame 1, a positioning mechanism 5 for positioning the mold base 2 at the processing station 6, a mold body 3 arranged on the mold base 2 and used for molding the insulating splint 200, and a lifting mechanism 4 that extends into the mold body 3 to lift the insulating splint 200 upward, thereby realizing the quick demolding action of the insulating splint 200 from the mold body 3.

[0033] A plurality of roller assemblies 11 are arranged in relative height alignment on both the front and rear sides of the frame 1. The front and rear two rows of roller assemblies 11 form two rows of sliding tracks 12 extending left and right, and the mold base 2 can move left and right on the two rows of sliding tracks 12. The two rows of sliding tracks 12 are provided to facilitate the mold base 2 to drive the mold body to smoothly move from one end of the frame 1 to the processing station 6. By moving to the processing station 6 in a sliding manner, the handling intensity is reduced and the work efficiency is improved.

[0034] Since the heights of the plurality of roller assemblies 11 are the same, the sliding track 12 is horizontally arranged. The roller assembly 11 includes a support base 111 fixed to the upper end of the frame 1, a rotating shaft 112 fixed to the support base 111, and a roller 113 rotatably arranged on the rotating shaft 112.

[0035] The positioning mechanism 5 includes a blocking module 51 arranged at one end of the frame 1 to block the mold base 2 from continuing to move forward, a front limit plate 52 for limiting the front side of the mold base 2, and a rear limit plate 53 for limiting the rear side of the mold base 2.

[0036] The front limit plate 52 and the rear limit plate 53 both extend horizontally and have the same height. The height of the mold base 2 is lower than that of the front limit plate 52 and the rear limit plate 53, and the width of the mold base 2 is shaped to be similar to the distance between the front limit plate 52 and the rear limit plate 53. The positions of the mold base 2, the front limit plate 52, and the rear limit plate 53 are set in this way so that the mold base 2 can smoothly move from one end of the frame 1 to the processing station 6 along the sliding track 12.

[0037] The blocking module 51 includes a blocking plate 511 that blocks the mold base 2 from moving forward and a first cylinder 512 that drives the blocking plate 511 to move up and down. The first cylinder 512 is fixed at one end of the frame 1. In order to improve the stability of the up and down movement of the blocking plate 511, a pair of first guide rods 513 are provided on the blocking plate 511.

[0038] The insulating clamping plate 200 includes an innermost fish tail plate 201, an outermost protective plate 202, and an insulating layer board 203 that bonds the fish tail plate 201 and the protective plate 202; the insulating layer board 203 is obtained by punching and forming a combination of four layers of PK4080 epoxy film and three layers of alkali-free glass fiber cloth.

[0039] The detailed structure of the mold body 3 has been disclosed in the patent with the Chinese patent authorization publication number CN202607885U and the name of a special mold for an insulating clamping plate, and will not be elaborated here. The positioning working surface of the mold body 3 is an arc surface, and the shape of the corresponding protective plate 202 is set to be similar to the positioning working surface of the mold body 3. The insulating layer board 203 is located between the protective plate 202 and the fish tail plate 201. After high-temperature processing, the insulating layer board 203 presents a molten state and thus bonds the protective plate 202 and the fish tail plate 201 together to obtain the insulating clamping plate 200.

[0040] In this embodiment, the mold body 3 extends in the left-right direction, and two mold bodies 3 are arranged side by side in the front-rear direction on the mold base 2. Therefore, two insulating clamping plates 200 can be prepared simultaneously. In other embodiments, the number of mold bodies 3 can be set according to the actual situation. In order to further improve the preparation efficiency of the insulating clamping plate 200, multiple mold bodies 3 can be provided on the mold base 2 to simultaneously complete the preparation of multiple insulating clamping plates 200.

[0041] The jacking mechanism 4 includes a plurality of ejector rods 44 that are movably arranged up and down on the mold base 2 and can extend into the mold body 3 to jack up the insulating clamping plate 200, a plurality of ejector pins 43 that are arranged corresponding to the plurality of ejector rods 44 and push the ejector rods 44 upward, a moving plate 42 for installing and fixing the plurality of ejector pins 43, and a second cylinder 41 that drives the moving plate 42 to move up and down. In order to ensure the stability of the up and down movement of the moving plate 42, a pair of second guide rods 45 are provided on the moving plate 42.

[0042] Two sets of sliding tracks 12 are arranged on the front and rear sides of the moving plate 42, and the height of the two sets of sliding tracks 12 is higher than that of the moving plate 42. Thus, a height space for the ejector rod 44 to move up and down is formed between the upper surface of the moving plate 42 and the lower surface of the mold base 2. In this embodiment, the ejector pin 43 protrudes from the upper surface of the moving plate 42 to facilitate smoothly lifting the ejector rod 44.

[0043] A first avoidance hole 21 for the ejector rod 44 to move up and down is provided on the mold base 2, and correspondingly, a second avoidance hole 31 for the ejector rod 44 to move up and down is also provided on the mold body 3 correspondingly.

[0044] The upper end diameter of the ejector rod 44 is larger than the lower end diameter, so a shoulder is formed on the ejector rod 44, so that when the ejector rod 44 moves downward, the shoulder of the ejector rod 44 can be restricted on the upper surface of the mold base 2 and will not fall off.

[0045] In this embodiment, ejector rods 44 are arranged on the left and right sides of each mold body 3. There are two mold bodies 3, so a total of four ejector rods 44 are provided, and the four ejector rods 44 are distributed at the four corners. Correspondingly, four ejector pins 43 are provided, and the four ejector pins 43 are distributed at the four corners of the moving plate 42. In other embodiments, the number and distribution of the ejector rods 44 are not limited, as long as the insulating splint 200 can be lifted efficiently.

[0046] When applying the preparation tooling 100 for an insulating splint provided by this solution, the mold base 2 enters from one end of the frame 1 through the sliding tracks 12, driving the mold body 3 to move to the processing station 6 together. During the movement, the front limit plate 52 and the rear limit plate 53 respectively guide and limit the front and rear sides of the mold base 2, so that the mold base 2 can smoothly move from one end of the frame 1 to the processing station 6 along the sliding tracks 12. When the mold base 2 moves in place, the first cylinder 512 drives the blocking plate 511 to protrude upward to block the mold base 2 from continuing to move. At this time, the mold base 2 is located at the processing station 6 and the positioning of the left end and the front and rear sides is completed, and the ejector rod 44 and the ejector pin 43 are directly vertically opposite. The protection plate 202, the insulating layer board 203 and the fish-tail plate 201 are sequentially placed in the mold body 3. After high temperature, the insulating layer board 203 melts and overflows glue to bond the protection plate 202 and the fish-tail plate 201 together to obtain the insulating splint 200. The second cylinder 41 drives the moving plate 42 to drive the ejector pin 43 to lift the ejector rod 44 upward, so that the ejector rod 44 lifts the insulating splint 200 upward, thus realizing the rapid demolding of the insulating splint 200 from the mold body 3. The insulating splint 200 is taken off and the next round of preparation of the insulating splint 200 is continued.

[0047] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several variations and improvements can still be made, and these all fall within the protection scope of the present utility model.
