The T connector end processes the shunting connectivity slot, respective line is connected into complete cooling water peripheral passage; The cooling water that will enter each branch line in the groove during work of shunting connectivity slot mixes, and makes temperature, and isostasy branches to out the groove water pipe with the cooling water behind the mixing simultaneously.
The out-of-shape of shunting connectivity slot is decided groove depth 30mm according to the distribution of water pipe gateway.For seal plug or Inlet and outlet water joint are connected with end face, around the shunting connectivity slot bolt hole is arranged, processing is used to place " " type groove of O sealing ring around the shunting connectivity slot; Sealing ring is put into groove during work, is positioned at the centre of seal plug and die body, connects die body and seal plug by bolt.
Seal plug is installed in mould shunting connectivity slot end, is used in combination with sealing ring, prevents the device that cooling water leaks, adopt the profile identical with die face, arranged around 10-12 connecting bolt hole is used to connect seal plug and die body, and the O RunddichtringO is compressed in the groove of die body.
The Inlet and outlet water joint, its shaped design and seal plug are basic identical.The shape consistent with die face adopted in the cross section.There are water inlet or delivery port in the centre, and joint has internal thread, is used for the connection of external cooling water pipe.10-11 bolt hole arranged around the joint, be used for being connected of joint and casting mould piece.
The beneficial effects of the utility model
The mould that the utility model provides is by pre-buried cooling water pipe, and the sectional type design of existing mold employing is being made on process-cycle and the cost and will significantly reduced relatively.Simplify the mold integral structure, assembling and setting is easy, and the reduction cooling water is revealed the frequency of defective, and working service is convenient, and mold integral processing, has reduced the accumulation of error of making and assembling, part type surface accuracy height.Can be applicable to the batch process of tide of motorism punching parts, will significantly reduce the production cost of drop stamping part and use threshold.
