Abstract
The invention discloses a mold pressure preventing device and method for hardware insert intra-mode injection molding. When an injection molding machine table operates normally for mold combining, a pressure value of a vacuum sucker adsorbing hardware to be molded in an injection mode is preset to be a standard pressure value, in the mold combining process, a pressure value actually obtained by a pressure sensor and a preset label pressure value are compared, if the pressure value exceeds the section range of the standard pressure value, it can be known that hardware falls off or moves, an injection molding machine can stop mold combining in time by means of power failure of an intermediate relay, and therefore the purpose of preventing a mold from being damaged by pressure and preventing the injection molding machine table from being damaged is achieved.
