Abstract
A modular system for blow molding a container. The system may include a first portion, a second portion, and a third portion. The first portion and second portion may each include a shell, a mold removably coupled to the shell, and a top plate. The third portion may include a base and a base mold. The molds may be 3D printed. The molds together may define a blow mold cavity. The modular system may be used at lab scale, pilot scale, or full production scale. The molds may be durable and smooth enough for full production scale. Some embodiments are directed to methods for making a modular system for blow molding a container.
Claims23
A modular system for blow molding a container, the system comprising:
- a first 3D printed mold portion;
- a second 3D printed mold portion;
- a 3D printed base mold portion;
- a shell comprising a first recess and a second recess, wherein the shell is removably coupled to the first 3D printed mold portion and the second 3D printed mold portion;
- and
- a base shell configured to couple to the first recess at a first position and the second recesses at a second position that is different than the first position,
- wherein the first 3D printed mold portion, the second 3D printed mold portion, and the 3D printed base mold portion are configured to define a blow mold cavity.
An interchangeable mold for blow molding a container, the mold comprising:
- a first 3D printed mold portion comprising a first flange;
- a second 3D printed mold portion comprising a second flange;
- a third 3D printed mold portion comprising a third flange;
- a fourth 3D printed mold portion comprising a fourth flange;
- a 3D printed base mold portion;
- a first retainer plate configured to couple to the first 3D printed mold portion and to the third 3D printed mold portion;
- and
- a second retainer plate configured to couple to the second 3D printed mold portion and to the fourth 3D printed mold portion,
- wherein the first 3D printed mold portion is interchangeable with the third 3D printed mold portion,
- wherein the second 3D printed mold portion is interchangeable with the fourth 3D printed mold portion,
- wherein the first 3D printed mold portion, the second 3D printed mold portion, and the 3D printed base mold portion define a first blow mold cavity for a container having a first height, and
- wherein the third 3D printed mold portion, the fourth 3D printed mold portion, and the 3D printed base mold portion define a second blow mold cavity for a container having a second height that is different than the first height.
A modular system for blow molding a container, the system comprising:
- a first mold half;
- a second mold half;
- and
- a base portion, wherein the base portion is configured to couple to a first recess of the first mold half at a first position along a height of the first mold half, wherein the base portion is configured to couple to a second recess of the first mold half at a second position along a height of the first mold half, and wherein the first position is different than the second position.
