[0049] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0050] like Figure 1 As shown, a mold changing vehicle of the utility model comprises a track trolley 1 and a track 2, and also comprises a bracket 3, a driving mechanism 4, a chain conveyor 5, a traction hook 6 and a roller conveyor line 7.

[0051] Among them, the rail trolley 1 is slidably set on the track 2, the track 2 is laid on the ground on the side of the pressure equipment, and the end of the track 2 away from the pressure equipment is connected to the mold placement table. The rail trolley 1 is provided with rail wheels and a motor, and the rail wheels and the motor are connected by chain transmission. The motor drives the rail wheels to roll on the track 2, so that the rail trolley 1 slides along the track 2 to transport the mold.

[0052] The bracket 3 is slidably arranged on the top of the rail trolley 1 along a first preset direction, and the first preset direction is a horizontal direction perpendicular to the rail 2, that is, the bracket 3 slides on the top of the rail trolley 1 along this direction; the driving mechanism 4 is fixedly arranged on the rail trolley 1, and is used to drive the bracket 3 to move back and forth on the top of the rail trolley 1; the chain conveyor 5 is fixedly arranged on the top of the bracket 3 and is parallel to the rail 2, and the chain of the chain conveyor 5 is hingedly connected to the traction hook 6; the roller conveyor line 7 is arranged on the side of the chain conveyor 5 and is parallel to each other, and the roller conveyor line 7 is fixed on the top of the bracket 3.

[0053] When replacing the mold, the chain conveyor 5 drives the traction hook 6 to move toward the mold placement table. A traction plate is fixedly set on the side of the mold, and a hanging hole is set on the traction plate. When the traction hook 6 is in place, the traction hook 6 is hung with the hanging hole, and then the chain conveyor 5 drives the traction hook 6 to move in the opposite direction, and the mold is pulled by the traction hook 6 to move the mold from the mold placement table to the roller conveyor line 7, and then the mold in place is transported to the side of the pressure equipment by the rail trolley 1, and then the traction hook 6 is driven by the chain conveyor 5 to move toward the processing table of the pressure equipment. During the process, the traction hook 6 pushes the mold from the roller conveyor line 7 to the processing table of the pressure equipment. After it is in place, the traction hook 6 is separated from the hanging hole.

[0054] During the process of replacing the mold, the hanging hole on the side of the mold may be misaligned with the traction hook 6. At this time, the driving mechanism 4 drives the bracket 3 to translate to correct the relative position of the hanging hole and the traction hook 6. After correction, it is convenient to hang the traction hook 6 on the hanging hole, thereby improving the efficiency of mold replacement.

[0055] To optimize the hanging, the end of the traction hook 6 away from the U-shaped hinge support 56 is bent downward by 90 degrees, that is, a 90-degree bend is designed at the end of the traction hook 6. When hanging, the traction hook 6 is vertically flipped so that the bent part is directly hung in the mold hanging hole.

[0056] In the above structure, the bracket 3 includes a frame body 31, a slider 32 and a slide rail 33, wherein at least two slide rails 33 are fixed on the top of the rail trolley 1, the two slide rails 33 are parallel to each other, and at least two sliders 32 are slidably arranged on each slide rail 33; the frame body 31 is fixedly arranged on the top of the slider 32, and one end of the frame body 31 is fixedly connected to the output end of the driving mechanism 4; the double slide rails 33 are arranged, so that the frame body 31 slides more smoothly.

[0057] The driving mechanism 4 includes a telescopic rod 41 and a push plate 42, wherein the telescopic rod 41 is horizontally arranged and fixedly arranged on the top inner side of the rail trolley 1, and the output end of the telescopic rod 41 is fixedly connected to the push plate 42; one end of the push plate 42 away from the telescopic rod 41 is fixedly connected to the frame 31, and the telescopic rod 41 is an electric push rod or a cylinder. When the telescopic rod 41 is working, its output shaft drives the push plate 42 to translate, and the push plate 42 drives the frame 31 to move.

[0058] In order to increase the movable range of the frame 31, a telescopic channel 101 is provided on the side of the rail trolley 1 at the position of the telescopic rod 41 along the first preset direction, wherein the telescopic rod 41 drives the push plate 42 to selectively penetrate the telescopic channel 101. Specifically, when the frame 31 translates, the telescopic rod 41 drives the push plate 42 to penetrate the telescopic channel 101, and the push plate 42 and the rail trolley 1 are avoided through the telescopic channel 101.

[0059] The chain conveyor 5 is mainly used for pulling the mold to move, and specifically includes a U-shaped chain box 51, a sprocket 52, a conveying chain 53, a driving motor 54, a connecting plate 55, a U-shaped hinge support 56 and a pin 57, wherein the U-shaped chain box 51 is fixedly arranged on the top of the frame 31; two sprockets 52 are rotatably arranged on the inner side of the U-shaped chain box 51, and the two sprockets 52 are connected by the conveying chain 53; the driving motor 54 is fixedly arranged on the side of the U-shaped chain box 51, and the output shaft of the driving motor 54 is fixedly connected to one of the sprockets 52; the connecting plate 55 is fixedly arranged on the side of the U-shaped chain box 51, and the output shaft of the driving motor 54 is fixedly connected to one of the sprockets 52; One end is arranged on the inner side of the U-shaped chain box 51 and is fixedly connected to the conveying chain 53, and the other end is fixedly connected to the U-shaped hinge support 56; the U-shaped hinge support 56 is slidably arranged on the top of the U-shaped chain box 51; one end of the traction hook 6 is arranged on the inner side of the U-shaped hinge support 56; the pin shaft 57 horizontally penetrates the U-shaped hinge support 56 and the traction hook 6 on the inner side of the U-shaped hinge support 56; in this structure, a wear-resistant steel plate is inlaid on the top surface of the U-shaped chain box 51, and the top surface of the wear-resistant steel plate is smooth. When the U-shaped hinge support 56 slides on the top surface of the wear-resistant steel plate, the resistance is small and it is not easy to wear.

[0060] Several roller conveyor lines 7 are symmetrically arranged on both sides of the chain conveyor 5 to support the mold. Specifically, the roller conveyor line 7 includes a U-shaped roller frame 71 and a plurality of rollers 72, wherein the U-shaped roller frame 71 is fixedly arranged on the top of the frame body 31; the plurality of rollers 72 are rotatably arranged on the top of the U-shaped roller frame 71, and the mold can slide on the roller conveyor line 7 through the U-shaped roller frame 71. When a mold is placed on the U-shaped roller frame 71, a gap of 10-50mm is reserved between the bottom of the mold and the top of the chain conveyor 5, so that there is no interference when the mold moves.

[0061] During the movement, the mold may slip off the roller conveyor line 7. To solve this problem, the mold changing vehicle also includes a limiting fence 8, wherein the limiting fence 8 is fixedly arranged on the side of the frame 31. Specifically, one is arranged on each side end of the frame 31 parallel to the track 2 to achieve lateral protection to prevent the mold from accidentally slipping. The limiting fence 8 includes a plurality of vertical plates, and the upper ends of the vertical plates are bent outward in an arc shape.

[0062] In addition, the rail trolley 1 may be unable to move due to a malfunction. In order to facilitate human intervention to move the rail trolley 1, a plurality of hanging rings 9 are fixedly provided on the side of the rail trolley 1, and the hanging rings 9 are used to connect to an external traction machine.

[0063] A method of using a mold changing vehicle of the utility model is as follows:

[0064] First, the chain conveyor 5 drives the traction hook 6 to move toward the mold placement table. After the traction hook 6 is in place, the traction hook 6 is hooked with the hanging hole on the side of the mold, and then the chain conveyor 5 drives the traction hook 6 to move in the opposite direction. The traction hook 6 pulls the mold to move, so that the mold moves from the mold placement table to the roller conveyor line 7.

[0065] The mold is then transported to the side of the pressure equipment by the rail trolley 1, and then driven by the chain conveyor 5 to move the traction hook 6 toward the processing table of the pressure equipment. During the process, the traction hook 6 pushes the mold from the roller conveyor line 7 to the processing table of the pressure equipment. After it is in place, the traction hook 6 is separated from the hanging hole.

[0066] During the hanging process, when the traction hook 6 is misaligned with the hanging hole on the side of the mold, the driving mechanism 4 drives the bracket 3 to translate, correct the position of the traction hook 6, align the traction hook 6 with the hanging hole on the side of the mold, and then hang the traction hook 6 with the hanging hole on the side of the mold.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
