    摘要： An improved injection blow molding machine has an melt accumulator or melt metering chamber and a vertically extending oval type die communicating therewith for injecting an elliptical annular parison through the die, which is to be blow molded to produce a hollow double wall type article. The oval type die includes a die housing and a mandrel mounted therein to define a melt passage therebetween having a die lip or opening of a four sided elliptical annular profile at a free lower end of the die. The accumulator is in direct contact with the mandrel, and/or the die housing is enlarged in a horizontal direction at a lower end portion thereof. Preferably the enlarged lower end portion is formed by a plate part fixed to a block part forming an upper portion of the die housing. More preferably, the plate part is fixed to the block part in a vertical direction but is allowed to horizontally move to some extent, and is provided with plural pairs of bolts and nuts for adjusting the die lip in a horizontal width direction with the each pair of opposite bolts being fixed to opposite margin portions of the plate part and biasing the block part against each other.
