Description

Quick locking and disengaging mechanism of floating core-pulling part in mold Technical Field The invention relates to the technical field of injection molds, in particular to a quick locking and disengaging mechanism of a floating core-pulling part in a mold. Background In the connector product injection mold, the conductive metal part is required to be embedded and then injection plastic rubber coating molding is performed, so that the product metal insert is automatically connected and placed in the mold for injection molding, the mold part is required to be designed into a floating core-pulling combined part, but the existing floating core-pulling combined part is locked to the side of a mold fixed template by manual operation, so that the whole product molding period is long, and the problem of potential safety hazard exists. Disclosure of Invention The invention aims to provide a quick locking and disengaging mechanism of a floating core-pulling part in a mold, which is used for solving at least one of the problems in the prior art. In order to achieve the above purpose, the present invention adopts the following technical scheme: The utility model provides a quick locking and breaking away from mechanism of part of loosing core in mould, includes fixing base, cylinder, swing joint spare, first hasp piece and second hasp piece, the fixing base is fixed on the mould fixed die plate, the cylinder is fixed on the fixing base, the piston rod of cylinder stretches out the one end and the swing joint spare fixed connection of fixing base, swing joint spare's both sides are connected with first hasp piece and second hasp piece rotation through the pin respectively, the symmetry is equipped with the recess on the fixing base, the lateral wall of recess is the position face, first hasp piece and second hasp piece are located corresponding recess respectively, the inboard of first hasp piece and second hasp piece has the latch hook, preliminary location has the combination part of loosing core on the mould fixed die plate, the piston rod of cylinder drives the swing joint spare and contracts, first hasp piece and second hasp piece receive the extrusion of position face and make first hasp piece and second hasp piece respectively around the pin clamp the clamping part of the combination part of loosing core until two latch hooks clamp. According to the technical scheme, as the air cylinder is fixed on the fixing seat, one end of the piston rod of the air cylinder, which extends out of the fixing seat, is fixedly connected with the movable connecting piece, after the floating core-pulling combined part is initially positioned on the fixed die plate of the die, the air cylinder is started, the piston rod is retracted, the movable connecting piece moves along with the piston rod, as two sides of the movable connecting piece are respectively connected with the first locking block and the second locking block in a rotating way through pins, in the process of pulling the movable connecting piece, the grooves are symmetrically formed in the fixing seat, the outer side walls of the grooves are respectively provided with a positioning surface, the first locking block and the second locking block are respectively positioned in the corresponding grooves, the inner sides of the first locking block and the second locking block are provided with locking hooks, in the process, the first locking block and the second locking block are respectively rotated inwards around the pins until the two locking hooks clamp the clamping parts of the floating core-pulling combined part, so that quick locking action is realized, and after locking, the die is assembled for injection molding. After injection molding is completed, a piston rod of the air cylinder stretches out to push the movable connecting piece forwards, and the first locking block and the second locking block rotate outwards around the pin respectively while being pushed, so that the floating core-pulling combined part is rapidly separated from the fixed die plate of the die.
