Embodiment Construction

[0030] Removable / replaceable integral heating device

[0031] figure 1A side cross-sectional view of a system 100 (eg, nozzle) according to one embodiment of the invention is shown. System 100 includes a nozzle body 102 having a melt flow path 104 . Melt flow channel 104 extends from manifold 106 through nozzle tip 108 . The nozzle body 102 also includes a heater retaining portion 110 (eg, an elongated heater retaining portion) for receiving a releasably secured heating device 112 (eg, a removable and / or replaceable heater). For example, the heater holding portion 110 includes a long or longitudinal groove 103 on the nozzle body 102 side. Heater 112 may be powered via connector 120, which may connect heater 112 to any type of power source. It should also be appreciated that all or part of the nozzle body 102 may be made of a material that is highly wear resistant and high pressure resistant, such as super high strength steel Aermet or any other material known in the art....

Abstract

A system and method including an injection molding system (e.g., nozzle) having a nozzle body with a heater holding portion that receives a heating device that is releasably secured in the heater holding portion. The nozzle has at least one flat or planar outer surface and can be made from a high wear and high pressure resistant material (e.g., Aermet). A slot of the heater holding portion and the heating device can be of complimentary geometries, such as rectangular shaped, wedge shaped, or any other shape. The heating device can include a holding device having receiving areas. Each receiving area can receive a respective heater that can be removed from the nozzle body. The nozzle body is provided with a clamping mechanism to insure an intimate contact between the heater holding portion and the heater device.

Description

[0001] Pursuant to 35 U.S.C. §119(e), this application claims the benefits of U.S. Provisional Application No. 60 / 432,986, filed December 13, 2002, entitled "Nozzles Having Removable and Replaceable Heating Devices and Methods of Making Same" priority, which is hereby incorporated by reference in its entirety. technical field [0002] The invention relates to the manufacture and use of an injection molding nozzle, which includes a detachable heating device and a heating device clamping mechanism connected therewith. Background technique [0003] Typically, injection molding nozzles have a nozzle body that includes a melt flow path adjacent to which is a heater element. Ideally, a heater within the nozzle would produce a constant or consistent viscosity and velocity of the molten flow of plastic material, resulting in a precise article with a uniform appearance. In a traditional injection molding system, when the heater starts to function incorrectly or fails completely, the...
