Abstract

A mold assembly for producing a part includes a first section, a second section movably coupled to the first section, and a cavity defined by the first section and the second section, the cavity being shaped to receive a part while the first section and the second section are movably coupled to each other. The mold assembly includes a joint formed by adjacent surfaces of the first section and the second section and a seal extending along the joint.

First claim

What is claimed is:

1. A mold assembly for producing a part, the mold assembly comprising:
a first section;
a second section movably coupled to the first section such that the second section is configured to move away from the first section during expansion of the part;
a cavity defined by the first section and the second section, the cavity being shaped to receive a part while the first section and the second section are movably coupled to each other;
a joint formed by adjacent surfaces of the first section and the second section;
a seal extending along the joint and spaced away from the cavity, the seal being breakable after the second section has moved away from the first section; and
a separation device that includes a scissor mechanism including a pair of legs configured to increase a distance between the first section and the second section.

2. The mold assembly of claim 1 , wherein the joint includes a seam extending between the first section and the second section and the seal includes a sealing material applied along the seam.

3. The mold assembly of claim 1 , wherein the separation device is configured to apply a force to linearly separate the first section and the second section.

4. The mold assembly of claim 1 , wherein the scissor mechanism includes a rod configured to increase the distance between the first section and the section sliding within a slide mechanism connected to a leg of the pair of legs.

5. The mold assembly of claim 1 , wherein the seal is formed with a frangible material that extends to a bottom edge formed by a seam of the joint.

6. The mold assembly of claim 5 , wherein the seam extends from the cavity to the bottom edge formed by the seam.

7. The mold assembly of claim 1 , wherein the pair of legs are configured to apply a force to linearly separate the first section and the second section.

8. The mold assembly of claim 1 , wherein the scissor mechanism includes a sliding rod extending across the pair of legs.

9. The mold assembly of claim 8 , wherein the sliding rod extends through a slide mechanism.

10. The mold assembly of claim 9 , wherein the sliding rod is fixed to a leg of the pair of legs.

11. The mold assembly of claim 1 , wherein the pair of legs forms a first pair of ends connected to the first section and to the second section, respectively, and a second pair of ends that extend away from the first section and the second section.

12. A mold assembly for producing a part, the mold comprising:
a first section;
a second section movably coupled to the first section;
a cavity defined by the first section and the second section, the cavity being shaped to receive a part while the first section and the second section are movably coupled to each other;
a joint formed by adjacent surfaces of the first section and the second section;
a seal extending along the joint; and
a scissor mechanism having a pair of legs, a slide mechanism and a rod extending through the slide mechanism and being secured to one leg of the pair of legs, the scissor mechanism being configured to move the first and second sections away from each other.

13. The mold assembly of claim 12 , wherein the slide mechanism is configured to permit sliding movement of the rod through the slide mechanism as the rod expands.

14. The mold assembly of claim 13 , wherein the slide mechanism is configured to restrict sliding movement of the rod through the slide mechanism as the rod contracts.
