There are four grooves 15, which are symmetrically distributed on both sides of the inner wall of the mold cavity 11. The stripping module 16 can form an inclined surface on the bottom surface of the oil pan that matches its contour. The cylinder 17 pushes the stripping module 16 to move toward the inside of the mold cavity 11. Then, under the action of the inclined surface of the stripping module 16, the oil pan can be pushed upward, and then the oil pan is separated from the mold cavity 11, so as to facilitate the separation of the oil pan from the inside of the mold cavity 11. It is simple and convenient to use.
[0024] Example 2: Figure 3-4 As shown: the injection holes 13 are opened on the longer side of the lower mold 1, and two are symmetrically arranged.
