Heat conduction structure for ceramic heater

Abstract

The present invention discloses a heat conduction structure for a ceramic heater. The heat conduction structure comprises a plurality of heat conduction module plates with fan-shaped sections, the left side wall and the right side wall of each heat conduction module plate are mutually inserted through a clamping mechanism, and every two heat conduction module plates are mutually inserted to form a heat conduction cylinder with a front opening and a rear opening. The heat conduction cylinder is arranged between an inner cavity of a ceramic heating cylinder and the outer wall of a material cylinder, multiple layers of outer adjusting plates used for changing the opening diameter of each outer contact opening are slidably inserted into the inner wall of each outer contact opening, and multiple layers of inner adjusting plates used for changing the opening diameter of each inner contact opening are slidably inserted into each inner contact opening. The heat conduction structure of thepresent invention reduces the loss of heat in air gaps, is more energy-saving and environment-friendly; the heat conduction module plates are designed in a modular mode, the integral heat conduction cylinder can be spliced according to the material cylinders of different sizes, so that the disassembly and assembly are easy, convenient and rapid, the service life is long, and the maintenance cost is low; the heat conduction structure is suitable for the material cylinders of different diameters and ceramic heating columns of different specifications, and the applicability is high.

Description

technical field [0001] The invention specifically relates to a heat conduction structure, in particular to a heat conduction structure for a ceramic heater. Background technique [0002] During the injection molding process of the injection molding machine, the plastic particles are first introduced into the push barrel, and the ceramic heater installed on the outer wall of the push barrel heats the push barrel. A plurality of rod-type ceramic heating rods are distributed along the inner wall of the barrel along the axis of the cylinder, and the ceramic heating rods are close to the outer wall of the barrel to heat the barrel. [0003] However, the ceramic heating rod of this kind of ceramic heater cannot directly contact the barrel, and a lot of heat is lost in the air gap between them. The heat conduction is not direct, and the heating efficiency is slow. filler or heat conduction medium, but the applicability is not strong, and it cannot be applied to various different b...

Problems solved by technology

[0003] However, the ceramic heating rod of this kind of ceramic heater cannot directly contact with the barrel, and a lot of heat is lost in the air gap between them, the heat conduction is not direct, and the heating efficiency is slow. Fillers or heat-conducting media, but the applicability is not strong, and it cannot be applied to various different barrels or different ceramic heating barrels. Therefore, to solve the above problems, we need ceramics that are always suitable for the external installation of various injection molding machine barrels.
