Abstract

The invention relates to a pouring method for pouring molding of a special-shaped coil former. The method includes the following steps that first, pretreatment of adhesives is performed, the adhesives are subject to defoaming treatment in stirring and pressure drop modes, and stirring under vacuumizing and stirring under ordinary pressure are carried out alternately; second, workpiece installation is conducted, and the coil former is placed into a molding tool; and third, filling and sealing are carried out, and a four-opening synchronous filling and sealing tool is used for pouring the four surfaces of the coil former at the same time. By the adoption of the tool and the pouring method thereof, the molding quality of coil pouring of a seeker product is guaranteed, reliable performance of the product is ensured, and production efficiency is improved.

Description

technical field

[0001] The invention relates to an infusion method, in particular to an infusion method for infusion molding of a special-shaped coil frame. It belongs to the technical field of assembly process of a certain product. Background technique

[0002] The process of pouring adhesives into special-shaped and narrow spaces is used in the potting of the coil skeleton of some products, mainly to insulate the copper coil from the outside world and fix the position of the copper coil. The coil bobbin is assembled on the outer edge of the gyroscope of some products, and the copper coil on it generates a magnetic field to control the orientation of the gyroscope of some products. The position and tightness of the copper coil directly affect its electrical and magnetic properties, which in turn affects the azimuth indication performance of some product gyroscopes and the reliability of the product.

[0003] The current coil bobbin is a special-shaped component composed o...
