Abstract

A mold can be receive mold inserts or submolds for customized configuration of the mold. In addition, the submolds can be specially configured for use. The same submold can be changed for a different use. Also, the submold can be reconfigured for use after the submold has been reconditioned. Moreover, the submolds make efficient use of materials within the mold by having many parts that are capable of reuse.

Claims (15)

1. A mold member cooperable with at least one other mold member for forming a mold capable of receiving fluidized material into the mold for molding objects from said material, the mold member comprising:

a plate having an opening therein defining a mold insert receptacle;

a mold insert adapted for insertion into the mold insert receptacle, the mold insert comprising a frame and plural mold insert components, at least some of the mold insert components having a cavity therein for receiving fluidized material to mold at least a portion of an object, the mold insert components being adapted for releasable attachment to the frame to form the mold insert;

a support plate having a central opening and ledges located for engaging the mold insert at a peripheral edge thereof for supporting the mold insert; and partitions capable of being received in the mold insert receptacle for dividing the mold insert receptacle into sections, and at least one of the partitions having a ledge adapted to support the mold insert.

2. A mold member cooperable with at least one other mold member for forming a mold capable of receiving fluidized material into the mold for molding objects from said material, the mold member comprising:

a plate having an opening therein defining a mold insert receptacle;

a mold insert adapted for insertion into the mold insert receptacle, the mold insert comprising a frame and plural mold insert components, at least some of the mold insert components having a cavity therein for receiving fluidized material to mold at least a portion of an object, the mold insert components being adapted for releasable attachment to the frame to form the mold insert; and plural mold inserts, the plate being adapted to receive the mold inserts in the mold insert receptacle in at least two arrangements which differ in the number of mold inserts along two nonparallel directions within the mold insert receptacle.

3. A mold member cooperable with at least one other mold member for forming a mold capable of receiving fluidized material into the mold for molding objects from said material, the mold member comprising:

a plate having an opening therein defining a mold insert receptacle;

a mold insert adapted for insertion into the mold insert receptacle, the mold insert comprising a frame and plural mold insert components, at least some of the mold insert components having a cavity therein for receiving fluidized material to mold at least a portion of an object, the mold insert components being adapted for releasable attachment to the frame to form the mold insert; and at least one partition selectively mountable on the plate in the mold insert receptacle for defining, in combination with the plate, mold insert receptacle sections.

4. A mold member as set forth in claim 3 wherein the partition has a thermal transfer system for use in exchanging thermal energy with at least one of the mold inserts in the mold insert receptacle.

5. A mold member as set forth in claim 4 wherein the plate has a thermal transfer system, and wherein the mold insert has at least two sides, one of the two sides engaging the plate for thermal energy transfer with the thermal transfer system of the plate and the other of the two sides engaging the partition for thermal energy transfer with the thermal transfer system of the partition.

6. A mold member as set forth in claim 3 wherein the partition is one of plural partitions capable of being selectively arranged in the mold insert receptacle to define sections for receiving respective ones of the mold inserts.

7. A mold member as set forth in claim 6 wherein the partitions are capable of being selectively arranged in the mold insert receptacle in plural arrangements in which the number of sections formed by the partitions among the arrangements differ along two nonparallel directions in the mold insert receptacle.

8. A mold member as set forth in claim 7 wherein the sections defined by the partitions in the mold insert receptacle are larger than the mold insert to be received in the sections when the mold insert is at a room temperature, and at a higher operating temperature at least one of the mold insert and partitions expanding to bring the mold insert and partitions into contact for conductive heat transfer between the mold insert and partitions.
