[0025] Specifically, the height of the mobile mold-changing trolley 1 can be adjusted by 0-80mm after loading. The charger of the battery module 2 is inside the vehicle body and can move with the vehicle. If the vehicle is out of power or insufficient, the on-board charger 201 only needs to pull a wire to power the vehicle. The vehicle does not need to go to a fixed place to charge, and the location of the charger is reduced, which effectively increases the utilization area of ​​the workshop. The overall structure adopts a double-beam structure with the characteristics of strong load-bearing capacity and stable force.

It is easy to replace and other characteristics. The wheels are covered with polyurethane rubber sleeves, which have long service life, high density and strong wear resistance. The push-pull device is composed of a double transmission screw and a double push-pull motor 304. The double transmission screw can meet the power of the mold to be transferred between the trolley and the equipment. A reinforcing beam 102 is arranged under the track to increase the stability of the slider 403 when running on the track and reduce the failure rate of the screw; to facilitate the position balancing of the two push-pull sliders 403, a single control switch needs to be installed on each motor; in addition, proximity switch sensing modules are installed at the corresponding positions on both sides of the trolley frame to prevent overload from causing damage to the screw and the motor. This trackless mold changing vehicle is not restricted by the site and can be moved freely on the flat ground. It can be used for multiple devices to replace molds, reducing the waste of site area. This mold changing trolley 1 is equipped with a lifting function with a lifting height of 0 to 80 mm, which can adapt to the replacement of molds by equipment with a height within the range. It is not necessary to equip each equipment with a mold changing vehicle, which can reduce the floor space.

[0026] The mold changing trolley 1 has a push-pull function with a push-pull speed of 1.77m / min. It uses a 1.5KW power motor to push and pull more than 1T. This function can avoid the problem of slow mold change or inability to change large-tonnage molds, and can improve equipment utilization. The trackless mold changing vehicle can replace a forklift to operate on site. The trackless mold changing vehicle uses a battery as a power source, so there is no pollution risk to the on-site environment and reduces the source of product odor pollution.

[0027] When working, the mold changing trolley 1 is loaded with the mold, and the trolley is moved to the vicinity of the press by the manual wireless remote control module in the mold area. The universal wheel 106 cooperates with the active wheel 6 to complete the positioning and guiding. After positioning, the hydraulic module 104 drives the lifting platform 103 to reach the required height of the overall mold changing trolley 1, adjusts the parameters of the electric control box 5, and the push-pull motor 304 drives the variable speed gear module to drive the transmission screw 302 along the positioning end 301. The push-pull device on the trolley table assists the operator to transfer the mold to the press, and the trolley returns to the mold library;

[0028] When the mold is disassembled, the empty trolley is manually controlled to be moved to the vicinity of the press and positioned. After positioning, the height of the trolley is adjusted to reach the required position. The trolley table push-pull device assists the operator to transfer the mold to the trolley, and the trolley transfers the mold to the mold warehouse.

[0029] Through the above steps, according to the previous use of forklifts and rails for manual mold changing, the forklift has a low safety factor when operating in the workshop and the exhaust gas has a greater impact on the environment. The difference is that the trackless mold changing vehicle is not restricted by the site and can be moved freely on the flat ground. It can be used for multiple devices to change molds and reduce the waste of site area. The mold changing trolley is equipped with push-pull functions. This function can avoid the problem of slow mold change or inability to change large-tonnage molds, and can improve equipment utilization.

[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
