ABSTRACT:
A mold structure has a plurality of article molds disposed in an array with an open central space. A gating system is connected with upper ends of the article molds and a base is connected with lower ends of the article molds. A baffle plate is inserted into the open central space between the article molds. The baffle plate has an area which is greater than the area of an opening in the base. A lower side of the baffle plate overlies an area on the base which extends completely around the opening in the base. To insert the baffle plate through the opening in the base, a slit is formed in the baffle plate. A portion of the base is received in the slit and then the baffle plate is rotated to turn it through the opening in the base. An alternative method of inserting the baffle plate is by partially folding the baffle plate and inserting the folded baffle plate through the opening in the base of the mold structure. Once the folded baffle plate has been moved into the open space between the article molds, the baffle plate is unfolded.
