Transfer molding insulation unit |
摘要 |
An apertured insulation unit is disclosed for interposition between a mold having at least one cavity in which elastomeric stock can be cured in the form of said cavity and an injection unit from which elastomeric stock can be expelled and transferred through the insulation unit to the mold cavity, the mold and injection unit being movable axially relative to one another into and out of pressing association with respective opposite side-faces of the insulation unit. The insulation unit serves to prevent curing of elastomeric stock remaining in the injection unit with the curing of the portion of such stock transferred to the cavity, without separation of either the mold or the injection unit from the insulation unit. The insulation unit is at least in part in the form of a thin, flexible, apertured plate constituted of a thermal-insulatory material which is engageable and forms a parting line with the mold.
