fig. 2 is a cross-sectional view of the utility model at the transverse waterway;

the mold comprises a male mold core 1, a female mold core 2, a mold cavity 3, a main runner 4, a branch runner 5, a sprue 6, a cold material well 7, an ejector pin 8, an upper outlet plate 9, a transverse water channel 10, an insert 11, a top rod 12 and an exhaust hole 13.

Detailed Description

Referring to fig. 1 and 2, an oil tank forming die comprises a core insert 1 and a cavity insert 2, wherein connecting plates on two sides of the core insert 1 and the cavity insert 2 are connected through bolts, grooves are formed in the lower end of the core insert 1 and the top end of the cavity insert 2, the grooves are combined to form a cavity 3, a pouring structure communicated with the cavity 3 and the outside is arranged on the core insert 1, a detachable insert 11 is inlaid on the cavity insert 2, an exhaust structure is arranged on the core insert 1 and comprises a plurality of exhaust holes 13 arranged on the core insert 1, a detachable outlet structure is arranged on the cavity insert 2, and transverse water channels 10 are arranged on the core insert 1 and the cavity insert 2. During specific implementation, the pouring liquid flows into the cavity 3 through the pouring structure, the gas in the cavity 3 is discharged through the exhaust holes 13, after pouring is completed, cooling water is continuously introduced from the water inlet of the transverse water channel to uniformly cool the product, the product is formed in a short time, then the core insert 1 is detached, and the finished product is ejected by using the ejection system. And finally, taking away the finished product, and resetting the male die core and the female die core.

In this embodiment, the pouring structure includes a main runner 4, a runner 5, a gate 6 and a cold burden well 7, the main runner 4 is narrow at the top and wide at the bottom, the narrow opening of the main runner 4 is communicated with the outside of the core insert 1, the wide opening of the main runner 4 is communicated with the runner 5, the runner 5 is directly connected with the gate 6, the cold burden well 7 is communicated with the main runner 4 and the runner 5 and is located below the main runner 4, and the gate 6 is communicated with the runner 5 and a groove at the lower end of the core insert 1.
