Abstract
Injection molding machine comprising at least one first and one second injection unit having a chamber for injecting a plasticized molding material and a piston for advancing a predetermined amount of plasticized molding material along a first axis from the chamber into a cavity of a mold, the machine including a form tool comprised of at least a first tool portion and a second tool portion, a tool cavity being at least partially disposed in the first tool portion.
Claims14
An injection molding machine for manufacture of molded parts from a plasticized material, comprising:
- at least one first injection unit having a chamber for injecting the plasticized material and with a piston for advancing a predetermined amount of the plasticized material along a first axis of the chamber into a first cavity of a first form tool, wherein the first form tool comprises at least one first tool portion and a second tool portion, wherein the second tool portion has at least one feed channel and the first cavity is at least partially arranged in the first tool portion,
- at least one second injection unit having a chamber for injection of the plasticized material and a piston for advancing a predetermined amount of the plasticized material along a second axis from the chamber into a second cavity of a second form tool, wherein the second form tool comprises at least one first tool portion and a third tool portion, the third tool portion having at least one feed channel and the second cavity being at least partially arranged in the first tool portion,
- wherein the second tool portion is arranged on a first tool or mold plate having at least one channel connecting the at least one feed channel to the first injection unit for injection of plasticized material into the first cavity,
- wherein the third tool portion being arranged at a second tool plate having at least one channel connecting the at least one feed channel to the second injection unit for injection of the plasticized material into the second cavity,
- wherein the first tool portions are separate from the second and third tool portions, and movable along a third axis arranged substantially perpendicular to the first and second axes,
- wherein at least two tool plates are arranged on a common tool plate support that is movable in the direction of the first and second axes,
- wherein at least two injection units for injection of plasticized material into a cavity of at least two form tools are arranged on a common injection unit support that is movable in the direction of the first and second axes, and
- wherein the common tool plate support and the common injection unit support, which are movable in the direction of a common axis, are movable independently of each other.
