Abstract
A mold insert set is provided for use with a mold system having first and second mold bodies, the first and second mold bodies aligning opposite each other during a molding process. Each of the mold bodies has at least one insert receiving region for replaceably receiving an insert of the mold insert set. Each of the inserts has an insert body, a mold cavity formed in the insert body, the mold cavity being for forming an object, and an opening in the mold cavity for aligning with a gas injection region of the mold body in which the insert is received. The gas injection region is where blow gas is introduced to the mold cavity for forming the object.
Claims27
A mold insert set for use with a mold system having first and second mold bodies, the first and second mold bodies aligning opposite each other during a molding process, each of the mold bodies having at least one insert receiving region for replaceably receiving an insert of the mold insert set, each of the inserts comprising:
- an insert body;
- a mold cavity formed in the insert body, the mold cavity being for forming an object;
- and
- an opening in the mold cavity for aligning with a gas injection region of the mold body in which the insert is received, the gas injection region being where blow gas is introduced to the mold cavity for forming the object.
A mold system for forming at least one object, the system comprising:
- a first mold body having
- at least one insert receiving region;
- and
- at least one gas injection region;
- a second mold body aligning with the first mold body and having
- at least one insert receiving region;
- and
- at least one gas injection region;
- and
- a plurality of mold inserts, each mold insert having
- an insert body;
- a mold cavity formed in the insert body, the mold cavity being for forming one of the at least one object;
- and
- an opening in the mold cavity for aligning with one of the gas injection regions,
- wherein each of the mold inserts fits into one of the insert receiving regions, and
- the gas injection regions are for introducing blow gas from outside the mold bodies to each of the mold cavities for forming the at least one object.
An extrusion-type blow mold machine, comprising:
- machine platens;
- and
- a plurality of two-part molds attached to the machine platens, each two-part mold having
- a first mold body having at least one insert receiving region and at least one gas injection region;
- a second mold body aligning with the first mold body and having at least one insert receiving region and at least one gas injection region;
- and
- a plurality of mold inserts, each mold insert having an insert body;
- a mold cavity formed in the insert body, the mold cavity being for forming at least one object;
- and
- an opening in the mold cavity for aligning with one of the gas injection regions,
- wherein each of the mold inserts fits into one of the insert receiving regions, and
- the gas injection regions are for introducing blow gas from outside the mold bodies to each of the mold cavities for forming the at least one object.
