Technical field
The utility model relates to casting technology field, specifically a kind of water cooling joint.
Background technique
Local cooling mode is generallyd use at present during low pressure casting and counter-pressure casting, after aluminum liquid filling type to casting
Each portion of part is cooled down, and to achieve the purpose that consecutive solidification simultaneously, is accelerated casting beat, is improved Die Casting efficiency, and
It can guarantee the mechanical performance and mechanical property of casting again.Such Local cooling mode is commonly called as " point cold ", and working principle is very
Simply, cooling water forms a circulation loop in mold position cylindrical hole to be cooled, and being exchanged by hot spot reduces mold temperature,
To reduce the temperature of casting in die cavity indirectly, achieve the purpose that cooling casting.
In traditional cooling joint, the surface of mold is provided with blind hole, and intermediate tube is inserted into the blind hole, the top peace of intermediate tube
Equipped with water inlet pipe and outlet pipe, an end cap of water inlet pipe is in intermediate tube and extends to blind hole end, and an end cap of outlet pipe is in
Between manage and water inlet pipe between centre.Actual in use, cooling water flows into arrival blind hole from water inlet pipe, at random from centre
Pipe flows through outlet pipe outflow, completes cooling procedure.This form cooling water and mold directly contact, due to cooling water temperature and
The mold temperature temperature difference is larger, and great thermal stress can be generated in cooling procedure, generates Quench phenomenon, if mold cooling-part week
Side wall thickness is relatively thin, easilys lead to die deformation, even crack of die under the chilling action of this periodical hot and cold alternation, and one
Denier crack of die just cannot permanently be repaired, only be scrapped.
It is " 206543871 U of CN " application No. is " 201720011916.6 ", Authorization Notice No., entitled " a kind of indirect
The Chinese utility model patent of water cooling joint " discloses a kind of indirect water-cooling but connector, the indirect water-cooling but connector packet
Water pipe head, copper core adapter body, admitting pipe joint composition are included, the copper core adapter body includes in fluid communication
Main body blind pipe part and main body junction portion, main body blind pipe part are installed in the blind pipe of die surface, main body connector portions
Divide the open connector of main body including two or more, the copper core adapter body is fixed to die surface, the water outlet
The quantity of pipe fitting and admitting pipe joint is respectively one or more, and is respectively fixed to the open connector of the main body, institute
The admitting pipe joint stated is connected into water diversion pipe, and Jinsui River diversion pipe extends to main body blind pipe partial interior.It should
The structure of indirect water-cooling but connector is complex, further, since water inlet pipe is located at center, outlet pipe is located at outer ring, and
Copper core adapter body structure further limits the speed of heat exchange, influences cooling effect.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of simple structure, convenient loading and unloading, installation
After in the aperture to cool down on mold for heat exchange, the water cooling joint with high efficiency and heat radiation effect.
In order to achieve the above object, the utility model provides a kind of water cooling joint, including water inlet pipe, outlet pipe and copper
Core joint body, the copper core joint body include the blind pipe being placed in mold cooling hole and are prolonged by the outward opening of the blind pipe
The copper core retaining ring stretched；
It is covered with lid on the copper core joint body, runs through on the lid and is equipped with the water inlet pipe and outlet pipe；
The outlet pipe is through the lid and extends at the blind pipe of the copper core joint body；
The water inlet pipe is made of straight tube and bend pipe, in which:
The tube wall of the straight tube is in hollow form, opens up several water inlets on the outside tube wall of the straight tube, the straight tube set
It is located between the outlet pipe and blind pipe；
One end of the bend pipe is pierced by the upper surface of the lid, and the other end of the bend pipe is connected to the outer of the straight tube
The top of side pipe wall.
Preferably, the water inlet end of the outlet pipe and plane where the blind pipe open end of the copper core joint body are neat
It is flat.
Preferably, the water inlet on the outside side wall of the straight tube is in average setting.
Preferably, the number for the water inlet that the exterior bottom of the straight tube opens up is four, this four water inlets are along straight
The circumferential direction of the exterior bottom of pipe is uniformly distributed.
The blind pipe of the copper core joint body is interference fitted in aperture of the die surface for heat exchange cooling.
The utility model has the beneficial effects that the cooling joint structure of this water is simple, easy to loading and unloading, it is mounted on mold and is used for
After in the aperture of heat exchange cooling, there is efficient heat dissipation effect, be evenly equipped with multiple cooling water intakes on the water inlet pipe, this
A little cooling water intakes cool down to copper core joint body, form heat exchange with mold indirectly, since water inlet is positioned at close
At copper core joint body, outlet pipe be located remotely from the center point of copper core joint body, such arrangement mode makes temperature higher
Water flow far from copper core adapter body, improve cooling effect.
