Description

Rotational moulding mould transfer car (buggy) Technical Field The utility model relates to a transfer trolley, in particular to a rotational molding die transfer trolley. Background The rotational molding die transfer trolley is a vehicle carrier for transferring rotational molding dies, the conventional transfer trolley only needs to simply load and carry the rotational molding dies to a processing position, so that the accuracy of the loading position of the rotational molding dies on the transfer trolley is not required to be guaranteed through additional structural design, however, in order to improve production efficiency, the transfer process of the rotational molding dies is required to be a part of automatic production equipment, for example, after the rotational molding dies are carried in place by the transfer trolley along a ground track, the rotational molding dies can be just connected with the subsequent automatic loading and unloading of the rotational molding dies, the loading position of the rotational molding dies on the transfer trolley is required to be quite accurate, the loading position is required to be positioned, displacement is not required to occur in the transfer process, the conventional transfer trolley is obviously difficult to achieve the use requirement, meanwhile, because the rotational molding dies on the conventional transfer trolley are simply placed and are not locked, the situation of dumping of the vehicle is also caused by starting or stopping and the like in the transfer process, a certain safety hazard exists, and particularly, the rotational molding dies are required to be completely loaded on the large-sized loading trolley or the carrier is required to be unloaded from a practical loading area, and the rotational molding dies can not be carried by practical lifting workers.
