Abstract
A hollow body forming mold includes left and right half molds, a bottom of the left half mold is provided with a left avoidance slot, a bottom of the right half mold is provided with a right avoidance slot, a left bottom slider is disposed in the left avoidance slot, a right bottom slider is disposed in the right avoidance slot, and the left and right bottom sliders constitute a group of sliders. The mold design resolves a difficult problem that a fabrication hole exists during forming of a hollow body with a built-in component by using an existing conventional process. The hollow body forming method has the advantages of a short forming period, the high production efficiency, good combination between a built-in component and an inner wall of an fuel tank, and the high location stability.
