The invention relates to the technical field of injection molds, in particular to a demolding mechanism of an injection mold for an automotive pillar trim panel.
Background
In the field of automobiles, a general automobile upright column is generally divided into an A column, a B column and a C column, wherein the A column is arranged between an engine compartment and a cab and above a left rearview mirror and a right rearview mirror, and can block a part of turning vision, particularly left turning, so that the discussion is more. The B column is arranged between the front seat and the rear seat of the cab, namely the longitudinal bar between the two doors at two sides, extends from the roof to the bottom of the vehicle, and the safety belt is arranged on the B column when viewed from the inner side. The C columns are arranged on two sides of the back seat headrest. In summary, the A, B and C pillars are the primary part of the structural strength of the supporting vehicle.
At present, an injection mold for an automotive pillar trim panel serving as an A-pillar generally adopts one mold and two molds, needs locking force in the X direction, the Y direction and the Z direction when the molds are locked, and also needs to be smoothly separated from the X direction, the Y direction and the Z direction when the molds are released, so that the integrity of the molded automotive pillar trim panel is ensured. At present, oil cylinders are mostly adopted in the X direction, the Y direction and the Z direction, so that six oil cylinders are needed for a single demoulding mechanism of a pair of injection moulds, and the appearance of the whole pair of moulds is too large and complex. In addition, when demoulding, the synchronism of the oil cylinders is required to be accurately adjusted, and in order to achieve the effect, the mould is required to have higher matching precision, so that the processing cost is greatly increased.
