Gateless Molding

View page
US Patent:
6645417, Nov 11, 2003
Filed:
Aug 5, 1999
Appl. No.:
09/369137
Inventors:
Dale Grove - Chelmsford MA, 01824
International Classification:
B29C 4502
US Classification:
2643288, 2643289, 26432811, 425562, 425577
Abstract:
Method and apparatus for forming an article from a molten plasticized resin using an injection molding machine by (a) forming a mold cavity having a first region for producing a molded part and a second, distinctive region for receiving a plasticised resin; (b) injecting into the second region a volume of plasticized resin for the article to be formed in the first region of the mold cavity; (c) applying pressure to plasticized resin to move it at least in part from the second region to the first region; and (d) maintaining pressure on the plasticised resin in the first region until the article is formed and stresses are relieved.

Injection Molding

US Patent:
59222662, Jul 13, 1999
Filed:
Oct 8, 1992
Appl. No.:
7/970608
Inventors:
Dale Grove - Billerica MA
International Classification:
B29C 4500
US Classification:
2642972
Abstract:
Method and apparatus for forming an article having a prescribed volume and mass from a molten plasticized resin using an injection molding machine by (a) forming an oversized mold cavity with respect to an opposing pair of relatively movable mold members between which the article is formed; (b) injecting into the oversized mold cavity a volume of plasticized resin exceeding the prescribed volume of the article and having a mass at least equal to the prescribed mass of the article; (c) applying force to the mold members to reduce the volume of the cavity and pressurize the plasticized resin therein simultaneously with the injection of resin.

Method For Simultaneous Injection And Compression

View page
US Patent:
59684399, Oct 19, 1999
Filed:
Jun 8, 1995
Appl. No.:
8/488623
Inventors:
Dale Grove - Chelmsford MA
International Classification:
B29C 4500
US Classification:
2642972
Abstract:
Method and apparatus for molding an article by forming an oversized mold cavity with respect to opposing relatively movable mold members, introducing material into the oversized mold cavity and applying force to the mold members to reduce the volume of the cavity and compress the material simultaneously with its introduction into the mold cavity. The result is simultaneous injection and compression of material by contrast with the prior art of simultaneous injection and volume reduction, where compression does not take place until after injection has been completed.

Control Of Fluid Flow

View page
US Patent:
52577708, Nov 2, 1993
Filed:
Apr 23, 1992
Appl. No.:
7/872403
Inventors:
Dale Grove - Billerica MA
International Classification:
F16K 704
US Classification:
251 4
Abstract:
Precision control of fluid flow by a body containing an inclined surface opposite an elongated opening, with a slider inserted into the opening to be movable along the opening in contact with discrete portions of the body which desirably includes a hinged detent for making contact with the body.
