Technical Field

The invention relates to the molding of fiber reinforced composite products, in particular to a mold positioning loose piece.

Background

After the fiber reinforced composite material product is stripped from the mold, the shape is uncertain in an elastic state before the fiber reinforced composite material product is connected and fixed with a structural part, and the hole characteristics on the fiber reinforced composite material product are difficult to position in the elastic state; sometimes, the tooling and the template are not easy to apply, and errors generated by operators and tools cause lower hole position precision and influence subsequent assembly. The precision of mould processing is high, fixes a position the hole of goods with the mould, can ensure positioning accuracy, also can ensure to be unanimous in batches.

The position of the product hole is positioned by using the die, and the use of the loose piece is a good method, and the loose piece is not only wear-resistant, but also can be recycled. However, in the existing loose piece technology, some parts to be positioned are bonded on the die in a low-strength mode, some parts are fixed on the die by bolts, and other parts to be positioned are arranged on the bolts in a similar mode and can be installed and detached from the back of the die. The existing loose piece technology is inconvenient to use and operate, or is taken down from a product in a shaking mode to cause local damage to the product, and the threads are easily stuck by resin.

Disclosure of Invention

The technical problem to be solved is as follows:

the blocking resin and the loose piece thread are not stuck, and the blocking material is not easy to fall off; when the movable block is fastened, the movable block is reversely fixed without a spanner, and the assembly and disassembly are easy to operate; the loose piece is easily removed from the article and has a low tendency to damage the article.

The technical scheme is as follows:

the positioning device comprises a positioning piece for positioning a hole, an embedded part embedded in a die, a loose piece bolt capable of fastening the positioning piece and the embedded part together, and a stop sleeve for limiting the rotation of the positioning piece relative to the embedded part when the loose piece bolt is fastened.

The positioning piece is provided with a threaded through hole and a protection groove; the threaded through hole is used for connecting the loose piece bolt and ejecting the positioning piece out of the product after the product is subjected to mold stripping; the threaded through-hole protection groove is used for fixing a material blocking resin, such as paper tape.

The stop sleeve can penetrate through the embedded part to limit the positioning part to rotate relative to the embedded part, and the stop sleeve can be installed in and taken down from one side of the embedded part. The loose piece bolt can penetrate through the stopping sleeve to fasten the positioning piece and the embedded part together, and can also be connected with the stopping sleeve to take the stopping sleeve out of the embedded part.

Has the advantages that:

the thread of the loose piece can not be stuck by resin, and the material for blocking the resin is firmly fixed and can not be scraped off in the process of forming the product; the loose piece is convenient to install and disassemble; the manner in which the loose piece is removed from the article is less prone to damage to the article.
