Abstract

The invention discloses a one-step molding process for an optical communication assembly seat. The one-step molding process comprises the steps of: preparation of a raw material, wherein a powder raw material is 304 stainless steel powder; preparation of a binder: mixing 70-80wt% of PW (Paraffin Wax), 5-20wt% of PE (Polyethylene) and 10-20wt% of SA (Stearic Acid) for 1-2 hours at the temperature of 140-160 DEG C; preparation of feeding: weighing the binder and the 304 stainless steel powder according to the volume ratio of (50-60):(60-50) and mixing for 1.5-2 hours at the temperature of 130-165 DEG C at the mixer rotation speed of 40-60r/min; injection molding: adding prepared feed into an injection molding machine for injection molding to obtain a blank, wherein the injection temperatureis 120-165 DEG C, the injection pressure is 60-120MPa and the mold temperature is 30-60 DEG C; treatment of the blank: dissolving a component PE of the blank, then drying the blank and degreasing theblank; and sintering of the blank: performing a sintering process by heating to high temperature of 1100-1350 DEG C at the temperature raise speed of 8-12 DEG C/min, preserving the temperature for 30-600min and cooling along with a furnace. According to the invention, assembly seat products with 45 degrees of inclined surface and high dimension precision and surface precision can be obtained by the injection molding.

Description

technical field [0001] The invention relates to a one-time forming process, in particular to a one-time forming process for an optical communication component seat. Background technique [0002] Optical fiber communication technology is a high-tech emerging in the early 1970s. It has been widely used in railway communication, electric power communication, military communication, cable TV, data communication system, etc. Many new application fields are still in development. We are constantly developing. Component holder is an important optoelectronic device for optical fiber communication, and has a huge market demand. The component seat is mainly prepared by machining method. Since the inside of the part has a 45° bevel, it cannot be formed at one time. At present, to solve this problem in industrial production, two parts are mainly processed, such as figure 1 , figure 2 shown, and then the final product is obtained by the method of assembly, such as image 3 shown. ...
