Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further details.
As shown in Figure 1, the present invention includes the upper die head fixed cover 2 being driven lifting by lowering or hoisting gear, it is characterized in that, described upper die head fixed cover 2 comprises the fixed cover arm 6 of some circumferentially angularly α settings, the holder arm 8 be connected with mold by bayonet apparatus is equipped with in each described fixed cover arm 6, described holder arm 8 comprises the first holder arm split 10 and the second holder arm split 12 be rotationally connected, described bayonet apparatus is arranged in the free end of described second holder arm split 12, described fixed cover arm 6 is by top board 14 and be separately fixed at described top board 14 both sides and the side plate 16 be parallel to each other forms, the chute 18 of up/down perforation is provided with in described top board 14, be provided with in described chute 18 and and can coordinate with described bolt 20 and be positioned at the nut 22 above described chute 18 along the bolt 20 of described chute 18 length direction slip, the head of described bolt 20 is square.
As a further improvement on the present invention, described angle [alpha] is 120 degree.
As a further improvement on the present invention, described upper die head fixed cover 2 is fixedly connected with a rotating shaft, described rotating shaft is provided with its whirligig moved in a circle of a driving.
As a further improvement on the present invention, described whirligig comprises the driven pulley 24 be fixed on described chosen axis, and to engage with described driven pulley 24 and to be driven the driving wheel 26 rotated by the first motor, described driving wheel 26 is partial gear, and described driven pulley 24 is provided with three sections of gear teeth and lock part.
