Description

A kind of continuous fiber reinforced plastic infiltrates mould

Technical field：

The utility model is related to field of die equipment, more particularly to a kind of continuous fiber reinforced plastic infiltration mould Tool.

Background technology：

A kind of high performance material of Long-fiber-reinforced thermoplastics, is the replacement production of traditional short fiber reinforced plastics Product, compared with the latter, mechanical property can improve 30~300%.

The conventional production process of Long-fiber-reinforced thermoplastics is：Continuous reinforcing fiber yarn beam is by an infiltration mould Tool, converges with the molten resin from extruder inside die cavity and is infiltrated by resin, the grain of certain length is cut into after depanning Material, its fiber is that continuous, used reinforcing fiber can be glass fibre or carbon fiber etc. along pellet length direction, utilizes this Thermoplastic bar, band, section bar of continuous lod etc. can also be produced by planting technique.

In order to allow resin to be thoroughly impregnated being transversely mounted a series of pins vertical with silvalin in all fibers, usual die cavity Nail, fibre bundle by when by bending repeatedly, yarn beam is deployed on pin, be easy to resin to enter single fiber.But prior art Fiber spreading width is small, it is necessary to which multiple pins can be only achieved effect.And bending times it is excessive when fiber stress it is excessive, it is easy to it is disconnected Split, cause to shut down.

In order to improve the dispersion effect of silvalin beam, bending number of times is reduced, some moulds are using cydariform or the pin of cone Nail, to allow yarn beam spreading to obtain wider.But because differed along the horizontal flow channel length of silvalin beam, when ripple occurs in mould cavity pressure Yarn beam often gathers flow channel length most short position when dynamic, and yarn Shu Jiju is caused on the contrary together.

Utility model content：

The purpose of this utility model is that there is provided a kind of infiltration of continuous fiber reinforced plastic in view of the deficiencies of the prior art Mould, warp architecture of the continuous fiber yarn beam from left to right successively with four cylindrical pins is in contact, and contact surface is arc surface, The effect that the spreading width fiber adjacent with allowing of silvalin beam mutually opens, and continuous fiber yarn beam and cylinder can be increased The curvature-adjustable section of the contact surface of pin, improves fiber dispersion effect, so as to reduce the situation of silvalin beam fracture, improves production Quality.
