Mold baking device

Abstract

The invention discloses a mold baking device, comprising two mold ovens, an air supply device, an ignition device and a mold oven support, wherein the mold oven support is arranged between the two mold ovens and welded and fixed to the two mold ovens; the tops of the mold ovens are open; the bottoms of the side walls of the mold ovens are provided with openings; the air supply device comprises anair source, a conveying pipeline, two air supply branched pipes and two flame nozzles; the air source is connected with the conveying pipeline; the conveying pipe is connected with the two air supplybranched pipes in parallel; each air supply branched pipe is connected with the corresponding flame nozzle; the frame nozzles pass through the openings of the mold ovens and extend into the mold ovens; the ignition device comprises a spark generating device which is arranged in a manner of passing through the openings and being close to the flame nozzles. The mold is simple in structure, convenient to use, high in safety coefficient, concentrating in fire, uniform in baking and rapid to reach the desired temperature and is capable of placing the mold into the mold ovens, saving baking time andfuel, increasing the service life of the mold, reducing production cost, and improving working efficiency.

Description

technical field [0001] The invention relates to the field of metal casting, in particular to a mold drying device. Background technique [0002] At present, most of the foundry industry adopts kiln-type mold drying furnaces. This type of equipment occupies a large area, and the energy utilization efficiency is low when heating and drying the molds. The heating is slow, and the products that need to be baked are heated unevenly, resulting in unqualified products; It is extremely inconvenient to take and place the product in the mold oven, and the degree of baking of the product cannot be observed at any time. The baking time can only be set based on experience, which is very easy to over-bake or under-bake. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a mold drying device with simple structure, convenient use, high safety factor, concentrated firepower, uniform baking, and the mo...
