Abstract

A mold injection tool includes a first mold plate having first and second columns of mold cavities, each of the cavities and a first cull block arranged between the first and second columns. A plurality of first channel sections is formed between an adjacent pair of mold cavities. Each of the first channel sections are configured to guide liquefied molding material from the first cull block into the adjacent pair of mold cavities in the first and second columns. The mold injection tool further includes a second mold plate having similarly configured mold cavities, cull block, and channel section. Adjacent ones of the first and second channel sections form a contained chamber when the first and second mold plates are pressed together. The mold plates are configured to inject liquefied molding material through an entrance that is in open communication with each contained chamber.
