[0013] (III) Beneficial effects

[0014] 1. The movement of the slide drives the hook to move, so that the hook moves toward the mold, and the electric cylinder is started to lift the hook upward, so that the hook on the mold is located at the notch, completing the connection between the hook and the mold. Then the slide and the hook move in the opposite direction, so that the mold moves with the movement of the hook, and the mold can be dragged from the platform to the lifting platform to complete the mold removal operation. Similarly, when a new mold needs to be installed, the mold can be pushed to the platform by moving the hook to complete the mold installation operation. The trolley can automatically change the mold, reduce manual operation time and physical exertion, and greatly improve the speed and efficiency of mold change.

[0015] Second: Fixed seats are fixedly installed at the four corners of the bottom of the base, and walking wheels are rotatably installed in each fixed seat. The walking wheels are controlled by a driving motor to rotate, so that the trolley can move flexibly and quickly in different areas, thereby improving the maneuverability and working range of the trolley.

[0016] Three: By starting motor three, screw one rotates, and the rotation of screw one drives the two sliders to move relative to each other (closer to each other or farther away from each other). The movement of the two sliders drives the two limit rods to move, thereby limiting the left and right sides of the mold to avoid position displacement during transportation. At the same time, it can also play a role in positioning and guiding the mold during installation, which helps to accurately install the mold and reduce installation deviations and errors.

[0017] Four: Fixed installation at the upper end of the lifting platform Due to the four slides, the four slides provide support for the mold. Rollers are equidistantly arranged in each slide, so that there is rolling friction between the mold and the slide, which greatly reduces the friction force, so that the mold can move more easily and quickly between the lifting platform and the platform, improving the efficiency and smoothness of mold change.

[0018] Five: Start motor four to rotate the four screw rods. The rotation of the four screw rods can drive the lifting platform to move up or down, thereby adjusting the height of the lifting platform and the mold. The height of the lifting platform and the mold can be flexibly adjusted according to actual needs to adapt to different work scenes and operation requirements, thereby improving the versatility and adaptability of the trolley.

Slide grooves 23 are provided on both sides of the upper surface of the lifting platform 2, and each slider 81 is movable through the slide groove 23. The lifting platform 2 is fixedly installed with a motor 3 82, and the output shaft of the motor 3 82 is fixedly connected with a screw rod 1 83, which is rotatably installed in the lifting platform 2, and the screw rod 1 83 passes through two threaded holes, and a motor 4 9 is fixedly installed in the base 1, and four screw rods 2 92 are rotatably installed on the base 1, and each screw rod 2 92 is threadedly connected with the lifting platform 2, and a gear group 91 for transmitting with the four screw rods 2 92 is provided in the base 1, and the motor 4 9 is used to drive the gear group 91 to operate, and a motor 5 for driving the slide 3 to move is provided on the slide rail 1 5, and the movement of the slide 3 drives the hook 4 to move, so that the hook 4 moves toward the mold direction, and the electric cylinder 31 is started to lift the hook 4 upward, so that the hook on the mold is located at the notch 41, completing the hook 4 and The mold is connected, and then the slide seat 3 and the hook 4 move in opposite directions, so that the mold moves with the movement of the hook 4, and the mold can be dragged from the platform to the lifting platform 2 to complete the demoulding operation. Similarly, when a new mold needs to be installed, the hook 4 can be used to move the mold to the platform to complete the mold installation operation. The trolley can automatically change the mold, reduce manual operation time and physical exertion, and greatly improve the speed and efficiency of mold change. The four corners at the bottom of the base 1 are fixedly installed with fixed seats 7, and each fixed seat 7 is rotatably installed with a walking wheel 71. The walking wheel 71 is controlled to rotate by a driving motor 72, so that the trolley can move flexibly and quickly in different areas, which improves the maneuverability and working range of the trolley. By starting motor three 82,The screw rod 83 is rotated, and the two sliders 81 are driven to move relative to each other (towards or away from each other) through the rotation of the screw rod 83.

The motor 4 9 is started to rotate the four screw rods 2 92. The rotation of the four screw rods 2 92 can drive the lifting platform 2 to move up or down, so that the height of the lifting platform 2 and the mold can be adjusted. The height of the lifting platform 2 and the mold can be flexibly adjusted according to actual needs to adapt to different work scenes and operation requirements, thereby improving the versatility and adaptability of the trolley.

[0031] Working principle:

[0032] In the first step, a motor 5 is provided on the slide rail 1 5 to drive the slide 3 to move. The movement of the slide 3 drives the hook 4 to move, so that the hook 4 moves toward the mold, and the electric cylinder 31 is started to lift the hook 4 upward, so that the hook on the mold is located at the notch 41, and the connection between the hook 4 and the mold is completed. Then the slide 3 and the hook 4 move in the opposite direction, so that the mold moves with the movement of the hook 4, and the mold can be dragged from the platform to the lifting platform 2 to complete the mold removal operation. Similarly, when a new mold needs to be installed, the hook 4 can be used to move the mold to the platform to complete the mold installation operation. The trolley can automatically change the mold, reduce manual operation time and physical exertion, and greatly improve the speed and efficiency of mold change;

[0033] In the second step, the four corners of the bottom end of the base 1 are fixedly installed with a fixed seat 7, and each fixed seat 7 is rotatably installed with a running wheel 71, and the running wheel 71 is controlled to rotate by a driving motor 72, so that the trolley can move flexibly and quickly in different areas, thereby improving the mobility and working range of the trolley;

[0034] The third step is to start the motor 3 82 to rotate the screw rod 1 83, and the rotation of the screw rod 1 83 drives the two sliders 81 to move relative to each other (towards or away from each other), and the movement of the two sliders 81 drives the two limit rods 8 to move, so as to limit the left and right sides of the mold, avoid position deviation during transportation, and also play a role in positioning and guiding the mold installation process, which helps to accurately install the mold and reduce installation deviations and errors;

[0035] The fourth step is to fix four slideways 22 on the upper end of the lifting platform 2. The four slideways 22 provide support for the mold. Rollers 24 are evenly spaced in each slideway 22, so that there is rolling friction between the mold and the slideway 22, which greatly reduces the friction force, so that the mold can move between the lifting platform 2 and the platform more easily and quickly, thereby improving the efficiency and fluency of mold change;

[0036] The fifth step is to start the motor 4 9 to rotate the four screw rods 2 92. The rotation of the four screw rods 2 92 can drive the lifting platform 2 to move up or down, thereby adjusting the height of the lifting platform 2 and the mold. The height of the lifting platform 2 and the mold can be flexibly adjusted according to actual needs to adapt to different work scenes and operation requirements, thereby improving the versatility and adaptability of the trolley.

[0037] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
