Disclosed herein, amongst other things, are various conversion structures for use in a molding system ( 100, 200 ). A non-limiting embodiment of the conversion structure includes a standard mold receiver ( 140, 157 ) and a mold conversion module ( 151 A, 151 B, 151 C, 251 A, 251 B, 251 C, 251 D, 251 E, 251 F, 152 A, 152 B, 152 C, 170 A, 170 B, 170 C). The standard mold receiver ( 140, 57 ) and the mold conversion module ( 151 A, 151 B, 151 C, 251 A, 251 B, 251 C, 251 D, 251 E, 251 F, 152 A, 152 B, 152 C, 170 A, 170 B, 170 C) are configured to cooperate, wherein the mold conversion module ( 151 A, 151 B, 151 C, 251 A, 251 B, 251 C, 251 D, 251 E, 251 F, 152 A, 152 B, 52 C, 170 A, 170 B, 170 C) is receivable in the standard mold receiver ( 140, 157 ) for converting a molding configuration of a mold ( 120 ).

First claim

What is claimed is:

1. Conversion structure for use in a molding system, comprising:
a mold receiver that is configured to receive a mold conversion module for converting a molding configuration of a mold;
the mold receiver includes a guide that is configured to cooperate with a complementary guide on the mold conversion module for accommodating repositioning, in use, of the mold conversion module between a molding position and an ejection position;
the mold receiver further includes a shutter device that is operable, in use, to selectively permit the repositioning of the mold conversion module.

2. The conversion structure of claim 1 , wherein:
the mold receiver is configured to accommodate several mold conversion modules arranged therein.

3. The conversion structure of claim 1 , wherein:
the mold receiver is configured for mounting to a platen of a mold clamp of the molding system.

4. The conversion structure of claim 1 , wherein:
the mold receiver is integrated with a platen of a mold clamp of the molding system.

5. The conversion structure of claim 1 , wherein:
the mold receiver is configured to accommodate repositioning of the guide to accommodate mold conversion modules with the complementary guide in different locations thereon.

6. The conversion structure of claim 1 , wherein:
the shutter device includes a shutter member that is configured to cooperate with a link member on the mold conversion module, wherein the shutter member is repositionable, in use, to selectively permit the repositioning of the mold conversion module.

7. The conversion structure of claim 1 , wherein:
the mold receiver further includes an ejector box for framing the mold conversion module at least in part.

8. The conversion structure of claim 1 , wherein:
the mold receiver includes a mold base that defines one or more interfaces that are configured to cooperate with one or more complementary interfaces that are defined on the mold conversion module.

9. The conversion structure of claim 8 , wherein:
the mold base includes a plurality of plates each of which defines the one or more interfaces.

10. The conversion structure of claim 9 , wherein:
the plurality of plates includes an inner core plate, an outer core plate and a stripper plate that define a inner core interface, a outer core interface and a stripper interface, respectively, for cooperating with a complementary inner core interface, a complementary outer core interface and a complementary stripper interface that are defined on an inner core, an outer core and a stripper sleeve, respectively, of a first stack portion of the mold conversion module.

11. The conversion structure of claim 8 , wherein:
the mold base is a cavity plate that defines a cavity interface for cooperating with a complementary cavity interface that is defined on a cavity insert of a second stack portion of the mold conversion module.

12. Conversion structure for use in a molding system, comprising:
a mold conversion module that is configured to be received in a mold receiver for converting a molding configuration of a mold;
the mold conversion module includes a complementary guide that is configured to cooperate with a guide on the mold receiver for accommodating, in use, repositioning of the mold conversion module between a molding position and an ejection position;
the mold conversion module is configured to cooperate with a shutter device that is associated with the mold receiver, wherein the shutter device is operable, in use, to selectively permit the repositioning of the mold conversion module.

13. The conversion structure of claim 12 , wherein:
the mold conversion module converts at least one of:
a cavitation of mold cavities in the mold;
a pitch of the mold cavities in the mold.

14. The conversion structure of claim 12 , wherein:
the mold conversion module includes a link member that is configured to cooperate with a shutter member of the shutter device, wherein the shutter member is repositionable, in use, to selectively permit the repositioning of the mold conversion module.

15. The conversion structure of claim 12 , wherein:
the mold conversion module includes a mold base having a first stack portion associated therewith, wherein the first stack portion is configured to define part of a mold cavity.

16. The conversion structure of claim 15 , wherein:
the mold base includes a plurality of plates each of which defines one or more interfaces.

17. The conversion structure of claim 16 , wherein:
the plurality of plates includes an inner core plate, an outer core plate and a stripper plate that define a inner core interface, a outer core interface and a stripper interface, respectively, for cooperating with a complementary inner core interface, a complementary outer core interface and a complementary stripper interface that are defined on an inner core, an outer core and a stripper sleeve, respectively, of the first stack portion.

18. The conversion structure of claim 12 , wherein:
the mold conversion module includes a mold base having a second stack portion associated therewith.

19. The conversion structure of claim 18 , wherein:
the mold base is a cavity plate that defines a cavity interface for cooperating with a complementary cavity interface that is defined on a cavity insert of the second stack portion.

20. The conversion structure of claim 12 , wherein:
the mold conversion module includes one or more of a first stack portion and a second stack portion that define one or more complementary interfaces that are configured to cooperate with one or more interfaces that are defined on the mold receiver.

21. The conversion structure of claim 20 , wherein:
