US 4,284,400 A · Positive extractor for cup molding machine

Abstract

There is disclosed a positive extraction mechanism for use in a textile molding apparatus preferably of the type having a female mold member and a male mold member. The mold members move into molding relationship with a fabric therebetween to form a cup-like article which is retained by one of the members. The positive extraction mechanism moves into intimate contact with the retaining mold member after the other mold member has been retracted. The extraction mechanism includes a plurality of pins which may be actuated by power means into engagement with the molded cup-like article. Each pin is spring biased away from the molded article so that the spring will retract its associated pin within the extraction mechanism upon removal of the power means. Upon retraction the molded article will leave the positive extraction mechanism. This occurs after the molded article has been carried away from the mold member.

Dependent claims

An extractor mechanism for disengaging a molded fabric article from a mold member comprising:

(a) an extractor body member adapted to be moved into mating relationship with a mold member after a fabric molding operation;
(b) pin means positioned in said extractor body member to move through openings extending through the outer perimeter of the extractor body member.
(c) means for causing said pin means to move through said openings into engagement with the molded article;
(d) means to move said body extractor member away from said mold member with molded article engaged by said pin means;
and
(e) means for retracting said pin means from engagement with the molded article after the extractor mechanism has been moved out of mating relationship with said mold.

A positive extraction mechanism for disengaging molded articles from a mold in a fabric molding apparatus wherein cup-like articles are molded between a female mold member and a male mold member, comprising:

(a) an extractor body adapted to move into and out of mating relationship with the molded article on one of the molded members;
(b) a plurality of pins operatively associated with said extractor body to move through openings extending through the outer perimeter of said extractor body;
(c) said pins having aligned so as to lie substantially at a right angle to the vertical axis of said mold members;
(d) means operatively associated with said pins to move said pins through said openings into engagement with the molded article so that the molded article is removed from the mold member when said extractor body is moved to a non-mating relationship with the molded member;
and
(e) spring means operatively associated with said pins means to urge said pin means out of engagement with the molded article so that the molded article can be disengaged from said extractor body.
