In this case, as shown in fig. 1 to 3, the casting mold includes a top mold base 2 and a bottom mold base 3 having an opening and closing displacement.
As shown in fig. 2, the bottom die base 3 includes a bottom die body 4, a casting channel 5 communicating with the bottom die body 4, and a first movable die 6 for forming a bent pipe body 12, a groove 61 for forming an extension end 13 is provided in the first movable die 6, a second movable die 7 for forming an inner channel of the double-row pipe body 11 is provided at a bottom end of the bottom die body 4, the first movable die 6 is provided with a lifting drive source, which is built in the bottom die base 3, illustration of the lifting drive source is omitted in the drawing, and the second movable die 7 is provided with a horizontal linear drive source 71.
The top die holder 2 is provided with a top die body 8 and a casting part 9, the casting part 9 is communicated with the casting channel 5, and a casting cavity of the double-row elbow connector is formed among the top die body 8, the bottom die body 4, the first movable die 6 and the second movable die 7.
Specifically, after the first movable mold 6 is lifted and the second movable mold 7 is linearly displaced, the mold is closed to form a casting cavity, after casting is completed, the first movable mold 6 is lowered to separate the first movable mold 6 from the bent pipe body 12 of the molded casting, and at this time, the mold is pressed in a mold closing state, so that the first movable mold 6 is not damaged to the bent pipe body 12 and the double-row pipeline main body 11 in the process of withdrawing the first movable mold 6.
And the double-row pipeline main body 11 of the casting is withdrawn through the second movable mould 7, and then the mould separation between the top mould base 2 and the bottom mould base 3 is carried out, so that the casting is easy to discharge from the mould, and the quality stability of the casting is ensured.
In a specific embodiment, a die holder lifting driving source 10 is disposed at the bottom of the die holder 3, a vertical lifting channel slidingly coupled with the first movable die 6 is disposed in the die holder 3, and the lifting driving source of the first movable die 6 is disposed at the bottom of the vertical lifting channel.
Specifically, since the vertical lift path and the lift drive source are both located in the bottom die holder 3, the drawings are omitted, and the principle of the operation is explained, the first movable die 6 has a relatively stable vertical displacement in the vertical lift path, and the lift drive source performs the lift displacement stroke.
