Embodiment Construction

[0023] The present invention will be further described below in conjunction with the examples, but not as a limitation of the present invention.

[0024] A method for preparing a front end part of a seat chassis of a continuous fiber reinforced thermoplastic composite material, the front end part of the seat chassis to be molded is as figure 1 As shown, it includes a main body, and the middle part of the main body is provided with an elongated hole 1 arranged horizontally, and the elongated hole 1 to the top side edge of the front end part of the seat chassis constitutes a beam 2 . Both ends of the beam 2 extend upwards from the beam to form a front connecting portion 3 . The axis of the front connecting portion 3 is perpendicular to the transverse axis of the beam 2 , and a flange 4 is provided on the shape edge of the front end part of the seat chassis.

[0025] The continuous fiber-reinforced thermoplastic composite material used in this example is a glass fiber-reinforced...

Abstract

The invention discloses a preparation method for a continuous fiber-reinforced thermoplastic composite seat base plate front end part, which includes the following steps: step 1, cutting a continuousfiber-reinforced thermoplastic composite sheet; step 2, feeding the cut continuous fiber-reinforced thermoplastic composite sheet to a drying oven for heating and softening; step 3, conveying the softened continuous fiber-reinforced thermoplastic composite sheet to a fixed die of a mould pressing injection mold, wherein a moving die of the mould pressing injection mold is provided with a pluralityof top blocks to sequentially compacting parts of the continuous fiber-reinforced thermoplastic composite sheet to the fixed die; step 4, performing die assembly to the moving die and the fixed die of the mould pressing injection mold for injection molding and pressure maintaining, and opening the mould to obtain the continuous fiber-reinforced thermoplastic composite seat base plate front end part. The method provided by the invention can solve the lacking of sheets near to an elongation hole or lacking of outer side edge sheets of the seat base plate front end part, and the fact that the sheet completely covers the seat base plate front end part is guaranteed.

Description

technical field [0001] The invention relates to a method for preparing an automobile seat chassis, in particular to a method for preparing a front end part of a seat chassis made of continuous fiber reinforced thermoplastic composite material. Background technique [0002] With the increasing demand for environmental protection, energy saving and emission reduction in the future society, the governments of various countries have more stringent regulations and requirements in this area. Facing the continuous upgrading of exhaust emission standards, the automobile industry needs to step up the realization of energy saving and emission reduction programs in many aspects. Formulated and implemented, automobile lightweight has once again become one of the focuses of many car companies. The current automobile structure and the use of metal materials have achieved relatively low material utilization rates to a large extent. Therefore, the use of composite materials that are lighter...
