摘要

A locking includes a locking member, a guiding rod, and a space member. The guiding rod is fixedly connected to the locking member. The mold includes a first mold plate, a second mold plate, a stripper plate, and a top plate. The first mold plate, the second mold plate, the stripper plate, and the top plate are connected in sequence. A receiving hole is defined in the first mold board. A through hole is defined in the second mold board corresponding to the receiving hole. The guiding member movably passes through the through hole. The through hole includes a first retaining portion and a second retaining portion. The space member is sleeved on the locking member. A diameter of the space member is greater than that of the receiving hole and the second retaining portion. The disclosure also supplies a mold.

主权项

1. A mold comprising:
a first mold plate defining a receiving hole; a second mold plate clamped to the first mold plate and defining a through hole corresponding to the receiving hole, the through hole comprising a first retaining portion and a second retaining portion coupled to the first retaining portion, wherein the first retaining portion is located adjacent to the first mold plate and the first retaining portion having a diameter being greater than a diameter of the second retaining portion; a stripper plate positioned adjacent to the second mold plate and away from the first mold plate, wherein the second mold plate positioned between the stripper plate and the first mold plate; a top plate coupled to the stripper plate away from the second mold plate, the stripper plate positioned between the top plate and the stripper plate; a locking device movably passing through the first mold plate and the second mold plate, the locking device comprising:
a locking member movably received in the receiving hole;a guiding rod coupled to the locking member with one end, the guiding rod passing through the first retaining portion and the second retaining portion away from the locking member;a space member sleeved on the locking member and positioned adjacent to the guiding rod, wherein the space member having a diameter that is smaller than the diameter of the first retaining portion but greater than the diameter of the second retaining portion; anda lever assembly movably passing through the first mold plate, the second mold plate, the stripper plate, and the top plate; wherein when the first mold plate is moved towards the second mold plate, the locking member and the guiding rod move towards the top plate; when in a mold closing operation, the first mold plate and the second mold plate move until the space member contacts an end wall of the first retaining portion, such that a partial portion of the guiding rod is exposed out of the through hole to push the stripper plate close to the top plate.
