Patent ID: 7641463

Claim:
A detecting apparatus, the detecting apparatus comprising: a mounting member comprising a first end surface and a second end surface that opposite to the first end surface, a through hole defined through the first end surface and the second end surface, wherein the mounting member is capable of being located at one side of a fixed mold plate; an elastic member received in the through hole of the mounting member; a contacting member received in the through hole and positioned near or at the first end surface; a sliding member slidably received in the through hole near or at the second end surface, wherein the elastic member is located between the contacting member and the sliding member; a blocking member attached to the first end surface of the mounting member; and a pressure sensor arranged between the blocking member and the contacting member, and engaging the contacting member; wherein the sliding member is biased by the elastic member, to be linear moveable in response to change of a contacted surface, the pressure sensor is capable of sensing deformation of the elastic member caused by the sliding member.
