Embodiment Construction

[0014] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0015] This embodiment provides an injection molding method for a skeleton instrument panel with a pipe beam insert, and the injection method includes the following steps:

[0016] Step 1: Mixing and plasticizing the raw materials;

[0017] Step 2: Melting the plasticized raw materials and forming a polymer film through a film die;

[0018] Step 3: Preheat the continuous fiber and disperse it for use;

[0019] Step 4: The continuous fiber and the polymer film are combined and sent to the twin-screw extruder for extrusion;

[0020] Step 5: The continuous fiber is cut by the screw and mixed into the pre-melted polymer;

[0021] Step 6: Push the mixture above into an injection mold for in...

Abstract

The invention aims at providing an injection molding method of a framework instrument panel of a pipe beam insert. After continuous fibers and a thin polymer film are converged, injection molding is carried out to manufacture the framework instrument panel of the pipe beam insert. The firmness and safety of the instrument panel are improved, the weight of the instrument panel is reduced, and the problem that the rigidity and energy absorption performance of the instrument panel cannot be achieved at the same time is solved.

Description

technical field [0001] The invention relates to the field of instrument panel manufacturing, in particular to an injection molding method for a skeleton instrument panel of a pipe beam insert. Background technique [0002] The instrument panel is located directly in front of the driver, and is generally equipped with odometer, speedometer, engine tachometer, fuel gauge and warning lights and other light signal indications on it. The driver can not only understand the basic driving status of the vehicle through the dashboard, but also control the air outlet, audio, air conditioning and lighting, so as to ensure safety while enjoying more driving pleasure. In recent years, with the continuous advancement of technology, more operating functions have been integrated into the instrument panel. Obviously, in order to ensure that the various instruments and parts supported can work normally under high-speed driving and vibration conditions, the instrument panel must have sufficient...
