Method for producing a metal elements-resin insert, a connector block for injectors, and a method for producing the connector block |
摘要 |
A metal elements-resin insert is produced by holding metal elements such as conductive bus bars 8 and the like in a forming cavity 5 of a mold assembly 3, 4 by a support pin 6 projecting in the mold assembly 3, 4. The metal elements 8 embedded in a resin material can overcome problems of corrosion and electrical short-circuit in which the metal elements contact with air or moisture entering through drawn holes 7 formed by support pin 6 into the resin material and can improve the moisture and air proof function. The resin insert is produced by: predeterminately forming preformed portions 13 which embed a main portion of the metal elements 8 in a resin material 1 and have a support pin aperture 7 which does not reach the metal elements 8 and adapts to receive a top end of the support pin 6 and have a positioning protrusion 15 which adapts to contact with the inner wall of the forming cavity 5; inserting the metal elements 8 with the preformed portions 13 into the forming cavity 5 so that the preformed portions 13 are pinched in the cavity between the support pin 6 received in the support pin aperture 7 and the positioning protrusion 15; and pouring a molten resin material into the forming cavity 5 so that the metal elements with the preformed portions are embedded in the resin material 1.
