Adjustable aligning device for large composite moulds
View Patent ↗An adjustable aligning device ( 300 ) for large composite molds comprising a first half part and a second half part includes a first member ( 1 ) and a second member ( 2 ) which are coupled to the first half part and the second half part of the molds respectively. The first member ( 1 ) and the second member ( 2 ) have mating portions and are capable of moving relative to each other. The adjustable aligning device ( 300 ) allows the fine calibration of overbite of the mold, and can reduce the time and skill needed for aligning the molds.
1. An adjustable aligning device for a large composite mould including a first half part and a second half part, wherein the adjustable aligning device includes a first member and a second member which are respectively coupled to the first half part and the second half part of the mould, and have mating portions and are capable of moving relative to each other, wherein the first member includes a base block connected to the first half part of the mould, a base plate detachably fastened to the base block, a nut member fixed to a bottom surface of the base plate and received in a space formed within the base block, the nut member being engaged with a threaded bar captured in the base block and rotatably supported in the base block, rotation of the threaded bar displacing the nut member along the threaded bar and within the space, and displacing in a displacement direction the base plate to which the nut member is fixed, and a male block protruding from the base plate, and wherein the second member includes a groove adapted to receive the male block.
2. The device of claim 1 , wherein the base plate of the first member is secured to the base block by means of a locking bolt(s) or screw(s).
3. The device of claim 2 , wherein the base plate comprises grooves running in a transverse direction which is aligned with the displacement direction, and each of the grooves has a width allowing passage of a main body of the locking bolt or screw and however being narrower than the diameter of a head portion of the locking bolt or screw, and four threaded holes are formed at corresponding positions of four corners of the base block, and the locking bolt or screw is inserted through the groove and corresponding threaded hole to thus fasten the base plate and the base block together.
4. The device of claim 1 , wherein a gap is provided between the first and second members and the second member is provided with a first hole orientated in the direction of the gap, and an adjustment bolt or screw is inserted through the first hole and a free end of the adjustment bolt or screw abuts against the first member when the groove receives the male block, an extension of the adjustment bolt or screw from the first hole being adjustable so as to adjust the gap between the first member and the second member, and thus the gap between the first half part and the second half part.
5. The device of claim 4 , wherein the second member is provided with a second hole communicated with the first hole, and a locking bolt is inserted through the second hole and bears upon the adjustment bolt or screw so as to lock the same in place.
