The outside of water collar body forms external screw thread, forms internal thread on the hollow bulb;
The top sleeve of lower cavity die is in die cap, die cap step on the die cap is being pressed topping bar of lower cavity die, the bottom sleeve of lower cavity die is in the receiving space of water collar, gasket seal be pressed in get out of a predicament or an embarrassing situation and the rim step between, flow deflector is pressed between the inner bottom part of lower cavity die bottom and water collar, and the outside of water collar forms the die cap internal thread of external screw thread on die cap and is screwed onto;
The outer cooling tube of the water outlet of piston rod is screwed onto on the internal thread on the hollow bulb of water collar.
Described current guided rings is protruded form lower cavity die recessed downwards and is gone out the bottom.
The current guided rings of moulding on the described lower cavity die has three.
Have four breach on protruding, the lower ring of described pressed on ring is protruding, the breach on the breach on pressed on ring is protruding and lower ring are protruding axially is staggered.
Form four notches that are periphery on the described die cap.
Beneficial effect of the present invention is:
1, in the outer setting of lower cavity die flow deflector, can cool off the lower cavity die periphery, improved production efficiency.
2, because can cool off lower cavity die bottom and periphery thereof, so also improve the bottle cap quality of item, can not produce the substandard products phenomenon that the bottle cap periphery has the bad initiation of the demoulding.
