検査作業の自動化の妨げになつていた。 Conventionally, the runners and gates of transfer molded products can be removed manually or by pressing, but manual methods require removal after the exterior is molded using a transfer molding machine, but before the resin is completely cured (approximately). If the runner and gate portion are not removed within 10 seconds, as shown in FIGS. 8 and 9, the surface of the molded product will be chipped and uneven projections will be formed due to the remaining gate portion. In addition, in the case of multi-cavity molded products, it is not only difficult to remove the runners and gates in a short time (within about 10 seconds), but also by hand, so chain leads, which are used as lead wires for electronic components, are difficult to remove. The line is easy to bend as shown in Figure 10. on the other hand,
When using a press, the shrinkage of the molded resin varies, so the position at which the gate part and the molded product are bent cannot be determined, and furthermore, when multiple runners and gate parts are removed, the surface of the molded product may be chipped, scratched, and the gate part may be damaged. An uneven protrusion is formed due to the residue.
Therefore, in the conventional means, bent lead wires, chips in the molded product, and protrusions caused by remaining gate portions not only deteriorate the appearance quality but also impede the automation of stamping work and characteristic inspection work in subsequent processes.
