Method for correcting shape of high-proportion glass fiber reinforced notebook computer face shell in thermal state

Abstract

The invention discloses a method for correcting the shape of a high-proportion glass fiber reinforced notebook computer face shell in a thermal state. The method comprises the steps that a shaping jigis installed on a shaping machine table, and an upper die of the shaping jig is opened; a product is put into a bottom die; the product is automatically put into the jig bottom die; automatic shapingof the shaping machine table is carried out; press fit is carried out inside the shaping machine table, the press fit temperature is controlled to be 490-510 DEG C, the time is controlled to be 15-20min, and the pressure is controlled to be 2-3.1 Mpa; and after press fit is completed, a profiling pressing block is lifted upwards by 2 mm and kept for 5 min or above, after the temperature inside the machine table is naturally reduced to 485 DEG C or below, the profiling pressing block is lifted to the highest position, and then the product is taken out of the jig bottom die. According to the method, shaping is carried out in the thermal state, the problem that shaping in a cooling state is poor is solved, and residual stress can be released so that the product cannot deform and rebound, and the shape correcting effect is good.

Description

technical field [0001] The invention relates to the technical field of 3C manufacturing, in particular to a method for correcting the shape of a notebook computer face shell in a hot state with a high proportion of glass fiber. Background technique [0002] PC+ABS engineering plastics are currently the most widely used materials in the notebook computer industry, because we can’t pick out any major faults in plastic materials in terms of cost, plasticity, weight or reliability, so we can say that plastics and electronic products are absolutely natural. pair. No matter what kind of process is used for plastic, it will be difficult to bring us the texture and psychological satisfaction of other materials such as metal in the end. Under this background, new materials and new processes have been developed to give consumers a new experience. Due to its physical characteristics, the new material is easy to be convex and deformed after injection molding, which runs counter to the ...

Problems solved by technology

Due to its physical characteristics, the new material is easy to be convex and deformed after injection molding, which runs counter to the original design intention of RD. After injection molding, manual shaping is a waste of manpower and the quality is different.
