Embodiment 1

[0032] like image 3 , 4 And shown in 5, a kind of sprue bushing of die-casting mold comprises a sprue bushing 1, and its outer cover is provided with sealing ring 2, and described sealing ring includes a cooling body 21 and the inlet that is located on the cooling body An end 22 and an outlet end 23, the inlet end and the outlet end communicate with the cooling pipeline 24 provided inside the cooling body respectively. The cooling pipeline is one of copper pipe, aluminum pipe, iron pipe or stainless steel pipe. The cooling lines are helical and are equally pitched. The outlet end and the inlet end are threadedly connected to the condensate circulation system. The cooling body is formed of cast aluminum or copper on the outside of the cooling pipeline.

[0033] When this embodiment is in use, the water sealing ring is set on the outside of the sprue sleeve, and the outlet end and the inlet end are connected to the external condensation circulation system through threads. S...

Embodiment 2

[0035] like Image 6 , 7 , 8 and 9, a sprue bushing for a die-casting mold includes a sprue bushing 1, and a water sealing ring 2 is set on its outer side, and the water sealing ring includes a cooling body 21 and is located on the cooling body The inlet port 22 and the outlet port 23 communicate with the cooling pipeline 24 provided inside the cooling body respectively. The cooling pipeline is a plurality of ring-shaped passages arranged inside the cooling body, two ends of adjacent passages are connected through a connecting passage 25, and the connecting passage is provided with an inlet end and an outlet end. The distance between adjacent channels is equal. The cooling body is cast aluminum or copper on the outside of the cooling pipe. .

[0036] When this embodiment is in use, the water sealing ring is set on the outside of the sprue sleeve, and the outlet end and the inlet end are connected to the external condensation circulation system through threads. Since the ...

Embodiment 3

[0038] like Figure 10 , 11 And shown in 12, a kind of sprue bushing of die-casting mold comprises a sprue bushing 1, and its outer cover is provided with sealing ring 2, and described sealing ring includes a cooling body 21 and the inlet that is located on the cooling body An end 22 and an outlet end 23, the inlet end and the outlet end communicate with the cooling pipeline 24 provided inside the cooling body respectively. The cooling pipeline is formed by bending a pipeline into an S shape first, and then bending it into a circle. The distance between two adjacent pipelines of the S-shaped cooling pipeline is equal, and the inner surface of the cooling pipeline is on a cylindrical surface. The cooling body Formed from cast aluminum or copper for the outside of the cooling line.

[0039] When this embodiment is in use, the water sealing ring is set on the outside of the sprue sleeve, and the outlet end and the inlet end are connected to the external condensation circulati...

Abstract

The invention discloses a pressure casting mold pouring gate bushing. The pressure casting mold pouring gate bushing comprises a pouring gate bushing, wherein a water seal ring sleeves the outer side of the pouring gate bushing, the water seal ring comprises a cooling body, and an inlet end and an outlet end which are arranged on the cooling body, and the inlet end and the outlet end are respectively communicated with a cooling pipeline in the cooling body. According to the pressure casting mold pouring gate bushing, a copper pipe or iron pipe coil is used as a cooling liquid circulation channel, cast aluminum or cast copper on the exterior of the pressure casting mold pouring gate bushing is used as heat conduction material, a quick connection copper pipe is screwed on the pressure casting mold pouring gate bushing through a pipe thread formed on a mouth of the pressure casting mold pouring gate bushing so as to connect the pressure casting mold pouring gate bushing with an external cooling circulation system, and therefore the pressure casting mold pouring gate bushing effectively guarantees that a cooling system can not leak, pass rate of pressure casting products is improved, and simultaneously cooling liquid can not directly act on the pressure casting mold pouring gate bushing, cold and hot violent change of pouring gate material is reduced, material cracking risk is reduced, and use life of the pressure casting mold pouring gate bushing is prolonged.

Description

technical field [0001] The invention relates to a sprue sleeve, more precisely a sprue sleeve suitable for die-casting moulds. Background technique [0002] The casting system of the die-casting mold is composed of sprue sleeve, runner, and gate. During the pouring process, the molten metal directly enters the mold cavity through the sprue sleeve, runner, and gate. [0003] The outside of the sprue sleeve of the die-casting mold in the prior art is provided with a sealing water ring, and a cooling liquid flow groove is arranged on the sprue sleeve. When the sprue sleeve is deformed, the coolant is prone to leakage, resulting in an increase in the defective rate of die casting products. When the coolant is directly used on the sprue sleeve material, the temperature difference between the inside and outside of the sprue sleeve will increase sharply, causing the material to crack easily and the life of the sprue sleeve will be reduced. Contents of the invention [0004] Due...
