Description

Technical Field

[0001] This utility model relates to the field of disassembly and assembly mechanism technology, and in particular to a quick mold changing device for a tire shaping vulcanizing machine. Background Technology

[0002] Currently, most known tire shaping vulcanizing machines use a movable mold structure. The movable mold is fixed to the connecting plate of the movable mold drive device and the vulcanizing chamber or support plate. In the actual mold replacement process, the mold needs to be fixed to the vulcanizing chamber or support plate externally with screws. The piston rod of the movable mold drive device is connected to the connecting plate with threads. Then, the vulcanizing machine is opened, and the mold is entered into the vulcanizing chamber. From the inside of the mold, the mold is fixed to the connecting plate of the movable mold drive device with screws. The operation is inconvenient and involves high temperature of the equipment. A search revealed that Chinese patent CN222987372U discloses a quick-change structure for a movable mold of a tire shaping vulcanizing machine, comprising a piston rod, a connecting shaft head, and a connecting plate. The key features are: a connecting shaft head connected to the bottom of the piston rod, a transition nut connected inside the connecting shaft head, the transition nut being threaded onto the bottom of the piston rod; a cross spline on the bottom of the connecting shaft head; a mating hole on the top of the connecting plate; four mating grooves evenly spaced along the circumference at the opening of the mating hole, the size of which matches the cross spline; and four positioning holes evenly spaced along the circumference on the connecting plate, each containing a steel ball, a spring, and a fastening bolt.

[0003] In actual use, this patent has the following drawbacks: During the use of the quick-change structure, the connecting shaft head needs to be inserted into the mating groove of the connecting plate, and the fastening bolt is rotated to compress the steel ball through the spring, so that the steel ball limits the connection shaft head and the connecting plate, and the connecting plate cannot guide the connection shaft head. As a result, when the quick-change structure is used, the connection shaft head needs to correspond to the mating groove of the connecting plate, which reduces the replacement efficiency of the quick-change structure.
