Medium frequency induction heating device for glass mold

Abstract

A medium-frequency induction heating device for a glass mold belongs to the technical field of auxiliary facilities for glass mold manufacturing. Including the machine frame, the top of the machine frame constitutes an organic platform, the bottom of the machine platform is formed as a water circulation cooling mechanism cavity, and the mold seat is set on the surface of the machine platform; the lifting mechanism of the medium frequency induction heating box is fixed on the machine platform; the medium frequency induction heating The box is set on the lifting mechanism of the medium frequency induction heating box. The coil of the medium frequency induction heating box is located outside the box of the medium frequency induction heating box. The coil is a tubular body with a hollow cavity. The coil structure is formed by repeated bending; the water circulation cooling mechanism is arranged in the cavity of the water circulation cooling mechanism, connected with the coil, and forms a water cooling circulation loop with the hollow cavity. Advantages: save energy, improve work efficiency; provide good protection for the coil; the structure is more concise.

Description

technical field [0001] The invention belongs to the technical field of auxiliary facilities for manufacturing glass molds, and in particular relates to a medium-frequency induction heating device for glass molds. Background technique [0002] The aforementioned intermediate frequency induction heating heats molds made of magnetically permeable materials such as carbon steel (also known as mold steel in the industry), copper alloys, and stainless steel in the form of heat generated by electromagnetic eddy currents. As is well known in the mold manufacturing industry, since the glass mold is in service, that is, the mold cavity is in direct contact with the molten glass melt frequently during use, it is subject to chemical erosion, wear and cold and heat alternating stress of the glass melt. At the same time, due to the long-term high temperature environment of about 500-800 ° C, the mold cavity of the glass mold will appear such as fatigue damage, oxidation and corrosion dama...

Problems solved by technology

[0007] But the above-mentioned technical scheme recommended by CN201039510Y has the following disadvantages: First, due to the need to use the advance and retreat oil cylinder and the lifting oil cylinder in the process of mold preheating, the advance and retreat oil cylinder guarantees The preheated mold enters or exits the lower position corresponding to the heating chamber of the intermediate frequency heating device in a horizontal motion, and the preheated mold is lifted into or out of the heating chamber by the lifting cylinder in a vertical motion , which not only increases the number of power mechanisms, but also is not conducive to energy saving, because the work of advancing and retreating and lifting cylinders needs to be supported by power sources; secondly, due to each preheating, it is necessary to move the preheated mold from side to side and up and down step by step Lifting once, so there are many action links, which affects the operating efficiency, that is, it is not enough to increase the output of mold preheating per unit time, causing the subsequent spray welding work to be in danger of slowing down; third, because the coil of the intermediate frequency heating device cannot be obtained Effective protection and the patent scheme does not give protection enlightenment, so it is easy to be damaged by the heat emitted by the hot mold; Fourth, because the device carrying the mold is a mobile trolley structure, it is relatively complicated, which increases the manufacturing and installation. difficulty
