A METHOD AND APPARATUS FOR MOLDING AN ELONGATED HOLLOW ARTICLE |
摘要 |
A molding apparatus includes a mold comprising a stationary outer mold with a substantially tubular mold cavity, a moveable end mold with an end mold cavity alignable with the tubular mold cavity, and a stationary elongated mold core with a fluid channel therethrough, the mold core extending through the tubular cavity into the end mold cavity. A method of using the apparatus includes injecting a molding material at a material flow rate into the mold, moving the end mold at a speed in a linear direction from a first position to a second position, supplying a fluid at a fluid flow rate to the fluid channel, and varying at least one of the material flow rate, the end mold speed and the fluid flow rate as the end mold moves from the first position to the second position. |
