A first transition member in contact with the nozzle tip is less thermally conductive than a second transition member in contact with the mold gate component. The valve pin when in the closed position makes sealing contact with at least the second transition member such that cooling from the mold gate component is transferred to the valve pin to cool the melt in the mold gate area. | 04-15-2010 |
20110064841 | Molding Apparatus for Modified Sulfur Concrete Substance Product - In the present invention, as a sulfur-containing material fully filled into a cavity of a mold body in which the inside of an outer mold having the cavity which can be hermetically sealed is heated to a temperature within a preset temperature range of which a lower limit is equal to or above a melting point of sulfur is cooled and contracted in the cavity, the sulfur-containing material stored in a filling tank in which a cover is attached to an upper end opening of filling tank, so that the inside of filling tank can be hermetically sealed, and also, the inside of filling tank is pressurized to a predetermined pressure, and the inside of filling tank is heated to a temperature within the preset temperature range, is replenished into the cavity by a pressure in filling tank to mold a modified sulfur concrete substance product. | 03-17-2011 |
20110287129 | Single Level Manifold for an Injection Molding Apparatus - An injection molding apparatus is disclosed having a single level manifold that utilizes a melt splitter. The manifold defines an inlet and a plurality of outlets with at least one upstream melt channel and a plurality of downstream melt channels that are situated between the inlet and the plurality of outlets. The upstream melt channel branches into the plurality of downstream melt channels with the upstream melt channel and each of the downstream melt channels longitudinally extending in the same plane. The melt splitter is at least partially positioned within the upstream melt channel where the upstream melt channel intersects with the plurality of downstream melt channels. The melt splitter divides a melt flow received from the upstream melt channel into substantially equal volumes and then directs each of the substantially equal volumes into a respective one of the plurality of downstream melt channels. | 11-24-2011 |
20110311676 | EDGE-GATED NOZZLE - An injection molding system is disclosed that includes a hot runner manifold for providing a melt stream of moldable material to at least one hot runner nozzle that is in fluid communication with one or more mold cavities via at least one injection manifold disposed proximate a downstream end of the nozzle. The at least one injection manifold has a substantially U-shape with at least one mold cavity being disposed between opposing arm segments thereof. Each mold cavity is fed by a pair of nozzle seals, wherein one of the pair of nozzle seals extends inwardly from one of the opposing arm segments while the other of the pair of nozzle seals extends inwardly from the other of the opposing arm segments for directing a melt stream into the mold cavity. | 12-22-2011 |
20120294975 | APPARATUS FOR MANUFACTURING VEGETABLE GELATIN CAPSULE - An apparatus for manufacturing a capsule by using vegetable gelatin is provided. Heating units are installed in a gelatin feeding line, which feeds gelatin in the form of a sheet, and a molding line to feed the gelatin in a predetermined temperature. The molded capsule is conveyed through a conveyer so that the molded capsule is stably dried and cured and a temperature of the conveyer is adjusted to control a temperature of the capsule. A length of the drying line is maximally increased within a narrow space, so that a film of the capsule made of the vegetable gelatin is gradually cured and dried without abrupt temperature variation, thereby preventing crack from occurring in the capsule, and preventing bonding parts of the capsule from being torn to improve the commercial value of the capsule. | 11-22-2012 |
20120294976 | INJECTION MOLDING APPARATUS - An injection molding apparatus is provided. The injection molding apparatus includes a mold, a plate heater mounted to the mold to heat the mold, and a cooling passage provided above or below the plate heater. | 11-22-2012 |
20120301571 | MOLD APPARATUS - The present disclosure relates to a mold apparatus, and according to an aspect of the present disclosure, there is provided a mold apparatus including a cavity mold comprising a cavity mold plate formed with a cavity at a front surface thereof and provided with a heating means at an inner portion thereof, and a cooling plate brought into contact with or separated from a rear surface of the cavity mold plate and provided with a cooling means at an inner portion thereof; and a core mold configured to determine the cavity together with the cavity mold plate, wherein the cooling plate is formed with at least two or more divided surfaces. | 11-29-2012 |

The feed channels on the top side of the first distributor plate are configured as open and the first distributor plate is monolithically formed together with the material pipes. An injection molding tool can be used with the component part and a method of making the component part is disclosed. | 09-25-2014 |
20160375621 | Injection Molding Apparatus Having Cooled Core Sliders - An injection molding apparatus is used for making parts having a hollow portion that is disposed under an angle relative to an axis. The molded parts are ejected when a movable stripper plate is displaced relative to the mold core used to cool the angled portion of the molded part. The stripper plate includes cooling channels and a cooling outlet. The cooling outlet is coupled to a cooling inlet of a movable cooling slider element. Leakage of a cooling fluid is prevented by using a sealing device and sealing elements between the cooling slider and a cooling manifold retaining the mold cores when the stripper plate is used during the ejection of the molded parts from the mold cores. | 12-29-2016 |
