Abstract

The invention discloses a die heating device which comprises combustion tube assemblies and gas tubes. The combustion tube assemblies are easily contained in an inner cavity of a die due to the sizes, the combustion tube assemblies comprise a plurality of transverse tubes and a plurality of vertical tubes, the transverse tubes are arranged at intervals from top to bottom, the transverse tubes are communicated through the vertical tubes, a closed shape is formed by each transverse tube, and a plurality of combustion spraying holes are formed in the peripheries of the tube walls of the transverse tubes and the vertical tubes. The gas tubes are communicated with the combustion tube assemblies, and gas valves are arranged on the gas tubes. By means of the die heating device, the die heating area is increased through the multiple combustion tube assemblies and the combustion spraying holes in the peripheries of combustion tubes, the die preheating efficiency is greatly improved, all parts of the die are evenly heated, and the die preheating quality is improved. A die preheating device is placed on the die in a balanced mode through a supporting piece, and even heating of the die is guaranteed.

Description

technical field [0001] The invention relates to the field of casting, in particular to a mold heating device. Background technique [0002] During the low-pressure casting process, especially the low-pressure casting of cast aluminum alloy, the mold needs to be preheated. In the prior art, a pipeline placed in the inner cavity of the mold is used, and the combustion gas is ejected from the end of the pipeline to heat the mold. However, this method can only heat part of the mold, the preheating process is relatively slow, and the efficiency is low, and each part of the mold is heated unevenly, and the thermal stress suffered is also different. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art.
