Abstract: PURPOSE:To prevent air from obstructing the injection or staying in a cured insulating material by a method wherein air is extruded into the atmosphere through holes bored in the board by injecting an insulating material continuously into the case through an opening formed between the periphery of the board and an inside periphery of the case. CONSTITUTION:A adequate number of holes 17 are bored in a board 10 before electronic components are mounted on the board 10 to form a circuit 16 (or after the circuit 16 is formed, if required). The holes 17 are bored on the part not occupied by electronic components such as an IC 11 or others. The shape and the number of the holes can be optionally preset so far as the strength of the board 10 is adversely affected. The board 10 formed as mentioned above is housed inside a case 20. A loop-like rectangular opening 21 is formed between the periphery 10a of the board 10 and an inside periphery 20a of the case 20. Then, when epoxy resin as an insulating material is continuously supplied into an inside cavity 23 through the intermediary of the opening 21, the epoxy resin 30 of an insulating material extrudes air stayed in the inside cavity 23 out to the atmosphere through the holes 17. Thus, the board 10 is immersed in the resin 30.

IPC: B22C9/00
Filed: 1992-01-31
Abstract: PURPOSE:To secure a gas venting passage by communicating a gas venting groove with a runner thereby mutually heating a molten metal and gas. CONSTITUTION:The gas generated from a cavity 4 passes through the gas venting passage 5, ascends in the inner part of a mold and reaches a shell core 6. Then, the gas passes through the gas venting groove in the shell core 6 and is discharged to the outer part of the mold 1. Since the high temp. molten metal flows in an opening part 7 in the shell core 6, the gas passing through the gas venting groove is heated by the molten metal. Therefore, a little quantity of molten metal incorporated in the gas is heated, as well and the inner part of the gas venting passage 5 is not clogged caused by the solidification of the molten metal therein.
