Heating material cylinder structure for injection molding machine

Abstract

A heating barrel structure for an injection molding machine, including an oil discharge pipe and a refueling pipe; the support collar is sleeved and supported on the outer wall of the annular oil tank, and the inner wall has six support plates in an annular array, and the support plates are fixed Supported on the outer wall of the annular oil tank; the heat-conducting air pipe runs through the annular oil tank, and it is sealed and fixed with the left and right ends of the annular oil tank by welding; the electric heating pipe is screwed on the left outer wall of the annular oil tank, and its The extension is inserted inside the annular oil tank. The heating barrel structure for injection molding machine is equipped with an annular oil tank, which is filled with heat-conducting oil. The electric heating tube heats the heat-conducting oil, and then heats the barrel body by the heat-conducting oil. The inside of the oil tank, and then the heat transfer oil evenly covers the surface of the barrel body, heating the barrel body in all directions without dead ends, so that the plastic particles inside are heated more evenly, thus shortening the melting time of plastic particles and reducing the use of electric energy.

Description

Technical field [0001] The invention relates to the technical field of injection molding machine accessories, and in particular to a heating barrel structure for an injection molding machine. Background technique [0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment that uses plastic molding dies to make thermoplastic or thermoset plastics into various shapes of plastic products. Divided into vertical, horizontal and all-electric. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. [0003] The inventor found that the heat preservation method of the existing heating barrel structure is mostly to directly bind the thermal insulation cotton to the outer wall of the heating barrel structure. There is no protective measure, and it is often scratched and torn. The thermal insulation cotton is often used for a long time. ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a heating barrel structure for injection molding machines to solve the problem that the thermal insulation cotton proposed in the above background technology has no protection measures, is often scratched and torn, and the plastic particles inside the heating barrel structure are heated Not uniform enough, the heating temperature control effect is poor
