发泡注塑模具的密封装置及方法

Sealing apparatus and method of foam injection mold

Abstract

本发明涉及一种发泡注塑模具的密封装置及方法,该发泡注塑模具的密封装置包括上模具,所述上模具布置在上侧作为注塑内芯的可移动模具与用以形成外皮的真空成形模具。所述上模具和所述真空成形模具一体地操作,并且下模具在所述内芯的注塑成形和发泡过程中使用。当所述内芯在所述上模具与所述下模具之间被注塑成形时,弹性密封单元与所述内芯一体形成,以便在所述下模具与所述真空成形模具结合时使用弹性恢复力来附接所述内芯和所述外皮,所述内芯在所述下模具中形成,所述外皮在所述真空成形模具中形成。所述弹性密封单元密封位于所述内芯与所述外皮之间的发泡空间。
The invention relates to sealing apparatus and a method of a foam injection mold. The sealing apparatus of a foam injection mold that includes an upper mold that is disposed on an upper side as a movable mold to inject a core and a vacuum forming mold to form a skin. The upper mold and the vacuum forming mold are operated integrally and a lower mold is used during injection-molding and foaming of the core. A resilient sealing unit is integrally formed with the core when the core is injection-molded between the upper mold and the lower mold, to attach the core and the skin while the lower mold in which the core is formed and the vacuum forming mold in which the skin is formed are combined using a resilient restoring force. The resilient sealing unit seals a foaming space between the core and the skin.
