Patent ID: 8425221

Claim:
A mold assembly having an ejection mechanism for forming a molded product having a lower wall and a side wall to commonly define a recess, the mold assembly comprising: a female mold; a male mold disposed corresponding to female mold, wherein the female mold and the male mold commonly define a mold cavity; a lower fixing plate disposed under the male mold, wherein the male mold and the lower fixing plate commonly define a receiving space therebetween; an upper ejection plate movably received in the receiving space, wherein a side surface of the upper ejection plate is formed with a receiving recess; at least one upper ejection pin mounted on the upper ejection plate, wherein one end of the upper ejection pin is correspondingly abutted against a position of the lower wall of the molded product closed to a side wall; a lower ejection plate movably received in the receiving space; at least one lower ejection pin mounted on the lower ejection plate, wherein one end of the lower ejection pin is correspondingly abutted against an end edge of the side wall of the molded product; and a process control mechanism having a side press block mounted on a side surface of the male mold, a transverse stop block movably received in the receiving recess of the upper ejection plate, an elastic member received in the receiving recess, and an upper push block mounted on a side surface of the lower ejection plate; wherein the side press block has a side press surface inclined extended therefrom; the transverse stop block has a guiding surface; the elastic member pushes an outer end of the transverse stop block out of the receiving recess; the upper push block pushes the outer end of the transverse stop block; and the side press surface of the side press block pushes the outer end of the transverse stop block into the receiving recess.
