Abstract
A modular pod for an injection mold includes a molding insert shaped to produce a molded part. The modular pod can be linked with a plurality of additional modular pods to form an injection mold. When a molding insert experiences a problem, the molding insert can be removed from the mold and replaced with a replacement insert. The modular pod employs a mechanical solution to eject the formed parts from the mold, without employing hydraulics.
Claims14
A method for ejecting a molded part from a mold comprising at least one molding insert removably coupled to a plate, the at least one molding insert comprising a first molding insert section and a second molding insert section that contacts the first molding insert section to form a molded part, a first sine bar coupled to the first molding insert section and a second sine bar coupled to the second molding insert section, the first and second sine bars each having a roller slot, and at least one roller coupled to each of the first and second molding insert sections, the at least one roller received in the roller slot of the first and second sine bar when the first and second molding insert sections are in contact with each other, the method comprising:
- activating the first and second sine bars to separate the first molding insert section from the second molding insert section;
- and
- moving the first and second sine bars along the first and second molding insert sections, said moving causing the at least one roller to roll out of the roller slot of each of the first and second sine bars and make contact with the first and second molding insert sections to release the molded part from the mold.
A modular pod for an injection mold, comprising:
- a first plate;
- a second plate adjacent to the first plate;
- a first molding insert releasably coupled to the first plate;
- a second molding insert releasably coupled to the second plate, the second molding insert configured to releasably contact the first molding insert to form a part mold, the second molding insert comprising:
- a first molding insert section;
- a second molding insert section adjacent to the first molding insert section and configured to make contact with the first molding insert section to define the second molding insert;
- a first sine bar coupled to the first molding insert section and a second sine bar coupled to the second molding insert section, the first and second sine bar each having a roller slot;
- and
- at least one roller coupled to each of the first molding insert section and the second molding insert section, the at least one roller configured to be received in the roller slot of each sine bar when the first molding insert section is in contact with the second molding insert section,
- wherein the first molding insert is configured to be removed from the first plate and the second molding insert is configured to be removed from the second plate upon malfunction.
An injection mold, comprising:
- a first modular pod comprising a first plurality of removable molding inserts;
- and
- a second modular pod comprising a second plurality of removable molding inserts, each of the removable molding inserts comprising:
- a first molding insert section;
- a second molding insert section adjacent to the first molding insert section and configured to make contact with the first molding insert section to define the removable molding insert;
- a first sine bar coupled to the first molding insert section and a second sine bar coupled to the second molding insert section, each sine bar having a roller slot;
- and
- at least one roller coupled to each of the first molding insert section and the second molding insert section, the at least one roller configured to be received in the roller slot when the first molding insert section is in contact with the second molding insert section,
- wherein each molding insert of the first plurality of removable molding inserts and the second plurality of removable molding inserts is configured to be removed when identified as malfunctioning.
