Glass die heating device

Abstract

The invention relates to a glass die heating device and belongs to the technical field of auxiliary facilities for manufacturing a glass die. The glass die heating device comprises a rack, a medium-frequency induction heating box lifting mechanism, a medium-frequency induction heating box, a water circulating cooling mechanism and a die temperature detection mechanism, wherein a machine table is formed at the top of the rack; a water circulating cooling mechanism cavity is formed below the machine table; a die placement seat is arranged on the surface of the machine table; the medium-frequency induction heating box lifting mechanism is fixed on the machine table; the medium-frequency induction heating box is arranged on the medium-frequency induction heating box lifting mechanism; a coil of the medium-frequency induction heating box is positioned outside a box body of the medium-frequency induction heating box; the coil is a tubular body with a hollow cavity; the coil is formed into a coil-shaped structure with a die extension cavity; the die extension cavity is correspondingly arranged above the die placement seat; the water circulating cooling mechanism is arranged in the water circulating cooling mechanism cavity; and the die temperature detection mechanism is arranged on the machine table and corresponds to the die placement seat. The glass die heating device has the advantages that the energy is saved and the operating efficiency is improved; the glass die heating device takes a good protection effect on the coil; the glass die heating device has simple structure; and the preheating temperature value of the die can be timely measured and the blindness is avoided.

Description

technical field [0001] The invention belongs to the technical field of auxiliary facilities for manufacturing glass molds, and in particular relates to a glass mold heating device. Background technique [0002] As is known in the glass 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, and is subject to chemical erosion, abrasion and alternating cold and heat of the glass melt. At the same time, due to the long-term high temperature environment of about 500-800 ℃, the mold cavity of the glass mold will appear such as fatigue damage, oxidation and corrosion damage, wear damage and / or impact damage, etc., which will affect its The service life is specifically manifested as early scrapping, which increases the cost of glass product manufacturers, and also causes waste of resources, which is contrary to the energy-saving economic spirit advocated by the whole society. ...

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. Fifth, because the actual temperature of the mold is difficult or even impossible to grasp during the heating process, it is blind
