MOLD CONVEYANCE GUIDE APPARATUS IN INJECTION MOLDING MACHINE
A mold conveyance guide apparatus includes: a linear guide that is attached along a conveyance direction of a mold to a mold attachment surface of at least one of a fixed platen or a movable platen to which the mold is fixed; a slider that is movably attached to the linear guide; and a coupling arm that is swingably attached to the slider in a direction coming closer to or separating from the mold attachment surface and is coupled to the mold in an engageable and disengageable manner.
DUAL MOLD SPACER
A dual mold spacer for use with a dual mold assembly is provided that includes a first side portion configured to engage a first side rail of the dual mold assembly. A second side portion is configured to engage a second side rail of the dual mold assembly. A body portion extends from the first side portion to the second side portion and is configured to be located between a press of the dual mold assembly and first and second molds of the dual mold assembly. The body portion is configured for being spaced from and free from engagement with the first and second molds.
WIND BLADE COMPONENT BONDING FIXTURE
The disclosed subject matter provides a system and method for facilitating bonding of various turbine blade components, including trailing edge inserts, or flatbacks, to the trailing edge of a wind turbine blade. The system disclosed herein ensures a consistent force is applied from root to top thereby preventing defects, e.g. paste voids, from forming. Additionally, a consistent bonding gap can be achieved due to the consistent application of force from the root to tip of the blade.
Master model having a complex shape, and kit for producing same
Disclosed is a master model (1) defining a useful surface having a complex shape, including a set of juxtaposed frames (2a, 2b, 2c), each frame including a panel having a useful edge (8), the frames being disposed parallel and held rigidly connected with predefined spacings such that the useful edges of same form the useful surface. The panel of each frame includes a blind slot (10) forming an opening passing through the thickness, and the frames are rigidly connected by a spar (3, 3a, 3b, etc.) suitable for being inserted (6) in the lengthwise direction (L) of same into the slots and including transverse notches (11) for receiving and holding the frames, each notch being arranged to receive, by a relative transverse translational movement (7) of the spar relative to the frames, the part in question of the panel of each frame.
A MOULD ASSEMBLY FOR MANUFACTURING A WIND TURBINE BLADE SHELL PART
The present invention relates to a mould assembly (100) for manufacturing a wind turbine blade shell part, and to a method of manufacturing a wind turbine blade shell part using the mould assembly (100). The mould assembly (100) comprises a lowering device (85), which is adapted to carry and lower a root end insert onto the moulding surface of the mould, the lowering device (85) being attached to the mould and comprising a frame (86) for carrying the root end insert. Two synchronized hydraulic cylinders (91, 92) are used as driving means for lowering the frame, each hydraulic cylinder comprising a piston chamber and a rod chamber, wherein the piston chamber and the rod chamber of each cylinder are connected to each other via a respective valve assembly (110) comprising a fluid line (96) and a valve (97).
MOVABLE PLATFORM FOR A MOULD SYSTEM AND METHOD FOR HANDLING A MOULD SYSTEM COMPRISING A MOVABLE PLATFORM
Disclosed is a mould system for moulding a blade shell of a wind turbine blade comprising a first mould for manufacturing a first blade shell part of the wind turbine blade; a second mould for manufacturing a second blade shell part of the wind turbine blade; a turning device configured to reposition the first mould between an open mould position and a closed mould position comprising a turning mechanism and a first primary beam connecting the turning mechanism and the first mould; a first scaffold arranged between the first mould and the second mould in the open mould position and comprising a first primary scaffold part and a first secondary scaffold part spaced apart by a first primary scaffold opening, the first primary scaffold allowing the first primary beam to move therethrough during repositioning of the first mould; a first primary movable platform attached to the first mould and being configured to move between an extended platform position and a stored platform position and covering the first primary scaffold opening in the extended position and arranged to expose the first primary scaffold opening in the stored platform position.
RIGID WIND TURBINE BLADE MOULD STRUCTURE CAPABLE OF RAPIDLY REPLACING MOULD PROFILE
A rigid wind turbine blade mould structure capable of rapidly replacing a mould shell without change of supporting structure of the mould includes a stationary supporting structure for supporting an upper mould and a lower mould and a clamping structure for clamping the upper mould and the lower mould; wherein if the mould shell on the supporting mechanism is the lower mould, to change a different mould shell type, there is no need to move the bottom support adjusting devices to support the lower mould, and only lift away the lower mould profile/shell structure by an overhead crane; if the mould shell on the supporting mechanism is the upper mould, the upper mould needs to be turned over to be above the lower mould through the hinge beam, and the hinge beam supporting structure stays.
HYBRID LAY-UP MOLD
A hybrid mold includes (a) an Invar eggcrate structure, (b) an Invar interim working surface and (c) a CF composite material overlay. The eggcrate and interim working surface are welded or otherwise connected together to form a unitary base mold. The CF overlay is bonded to the interim working surface. The CF overlay is easily reconfigurable and can be replaced without destroying the integrity of the base mold.
SINGLE-PIECE MOLDED FRAME FOR A COMPOSITE LAY-UP SKIN
The invention relates to a frame (2) including at least one part that is intended to support a skin (3) for receiving a part made from a composite material to be polymerized in an autoclave, said skin (3) defining the general shape of said part. The frame (2) is characterized in that it is a single-piece foundry piece.
Preform station and method
A preform station for forming a flexible semi-finished product and for transforming a flexible semi-finished product into a geometrically stable preform is provided. The preform station comprises a first pin array having a multitude of pins, on which the semi-finished product can be draped. Furthermore, the pins are movable along their longitudinal directions in order to form the flexible semi-finished product. Furthermore, the preform station comprises an activation device for activating a binder of the semi-finished product such that the semi-finished product can be transformed into the geometrically stable preform.
