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 method for preparing a front end part of a seat chassis of a continuous fiber reinforced thermoplastic composite material, comprising step 1, cutting the continuous fiber reinforced thermoplastic composite material sheet; step 2, cutting the continuous fiber reinforced thermoplastic composite material in step 1 The sheet is sent into an oven to be heated and softened; step 3, the softened continuous fiber reinforced thermoplastic composite sheet is sent to the fixed mold of the molding injection mold, and the movable mold of the molding injection mold is provided with several top blocks in sequence Several parts of the continuous fiber-reinforced thermoplastic composite material sheet are compacted on the fixed mold; step 4, the movable mold of the molding injection mold is clamped with the fixed mold and injected to hold the pressure, and the continuous mold is obtained after the mold is opened. Fiber-reinforced thermoplastic composite seat pan front end. The method of the invention can solve the problem of missing sheets near the elongated hole of the front end part of the seat chassis and the outer edge, and ensure that the sheet completely covers the front end part of the seat chassis.

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...
