Apparatus and method for injection molding. |
摘要 |
<p>Improved apparatus and method for injection molding plastic material including a stack mold (10) and an injection unit with movable sprue bar (43) communicating with a runner system (41). Means are provided to releasably engage the sprue bar with the runner system by relative movement in a direction perpendicular to the horizontal central axis (14) of the stack mold (10). The sealing action of the sprue bar (43) with the first runner system (41) occurs by a motion perpendicular to the clamping axis (14). There is no difference in the clamping force applied to each half of the stack mold (10).</p> |
