249063000 | MOLD INCLUDING CORE AND MEANS TO REMOVE CORE | 6 |
20090121115 | Collapsible core assembly for a molding apparatus - A collapsible core device for molding articles around the core device in a mold cavity includes an expansion member, a discontinuous first sleeve and a discontinuous second sleeve. When the expansion member is fitted within the first and second sleeves, the expansion member and the first and second sleeves form a substantially continuous, flush top molding surface with the first and second sleeves. | 05-14-2009 |
20090266971 | MOLD RELEASING DEVICE AND MOLD RELEASING METHOD - A mold releasing method for releasing a core member from a mold includes steps of: a)providing a supporting member and arranging the supporting member on the mold, the supporting member comprising a base and a number of sidewalls extending from the base to the mold, a through hole being defined in the substrate and co-axially aligned with the core member; b) providing a bolt, the bolt comprising a threaded rod extending through the through hole of the substrate and threadedly engaged with the core member; and c) rotating the bolt to move the core member to disengage from the mold. | 10-29-2009 |
20090302191 | MOLDING DEVICE AND METHOD FOR MAKING MOLD CORE - A molding device includes a mold and a mold core received in the mold. The mold has an insert receiving cavity defined therein and an inner surface in the insert receiving cavity. The mold core includes a core insert and a connection portion. The core insert has a molding surface defined at a first distal end thereof and a lateral surface. The lateral surface of the core insert contacts the inner surface in the insert receiving cavity. The connection portion has a distal end connected with an opposing second distal end of the core insert. The connection portion is received in the insert receiving cavity and spaced from the inner surface of the mold. | 12-10-2009 |
20130146744 | MOLD WITH WATER-COOLING CHANNELS - A mold includes a first mold base, a second mold base, a core and at least one sliding block. The second mold base engages with the first mode base. The core is fixedly positioned in the second mold base. The at least one sliding block is slidably positioned on the second mold base and positioned adjacent to edges of the core. A plurality of first cooling channels is defined in the core. The at least one sliding block and the core cooperatively form a molding space. A second cooling channel is defined in each sliding block. | 06-13-2013 |
20150069212 | Inflatable Inverse Concrete Coil Form - A system designed to create the inverse shape of an object inside of wet concrete until hard, using and inflatable form. The inflatable inverse concrete coil form has the advantage of lower cost, can be reused, and has the ability to create shapes that would be impossible to make with ridged forms, or in limited space. The system advances the practical abilities of concrete by gaining its entire form structure through internal forces, and uses liquid as a ballast to achieve neutral buoyancy against the float force in wet cement. | 03-12-2015 |
249064000 | Plural cores | 1 |
20100006739 | Composite Mandrel For Autoclave Curing Applications - A composite mandrel includes a generally elongated mandrel body comprising a resilient mandrel core and an elastomeric mandrel outer layer disposed outside the mandrel core. A method for fabricating a contoured stiffened composite panel is also disclosed. | 01-14-2010 |
