Problems solved by technology
Differential pressure molds mostly use flame preheating. Due to the high flame temperature and heat concentration, the mold will withstand high alternating thermal stress, which is prone to cracking and shortens the life of the mold.
At the same time, due to the different sizes of castings and molds, the mold preheater has poor versatility

The invention provides a mold preheating system and a preheating method. A hot air accumulation barrel with an upward opening is fixedly arranged on a preheating workbench of the preheating system, and an air blowing plate fixedly covers a barrel opening of the hot air accumulation barrel; an inner hot air gathering cavity, a middle hot air gathering cavity and an outer hot air gathering cavity are formed in the hot air gathering barrel, an air inlet pipe at the barrel bottom of the bottom of each hot air gathering cavity is connected with air outlets of the three heat supply devices, and a circle of multiple air blowing holes are formed in the plate face of the top of each hot air gathering cavity. Through selective on-off control of the three heat supply devices, the blowing holes of the inner ring are used for blowing hot air to preheat a small mold, the blowing holes of the inner ring and the middle ring are used for blowing hot air to preheat a middle mold, and the blowing holes of the inner ring, the middle ring and the outer ring are used for blowing hot air to preheat a large mold; a large heat preservation cover, a medium heat preservation cover and a small heat preservation cover are placed on one side of the preheating workbench and used for covering the large mold, the medium mold and the small mold in the preheating process. The mold heating device can realize uniform heating of molds with different sizes.
Description
technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a mold preheating system and a preheating method. Background technique [0002] In the manufacturing process of auto parts, the differential pressure mold needs to be heated. Differential pressure molds mostly use flame preheating. Due to the high flame temperature and heat concentration, the mold will bear excessive alternating thermal stress, which is prone to cracking and shortens the life of the mold. At the same time, due to the different sizes of the castings produced, the size of the molds is also different, and the versatility of the mold preheater is poor. [0003] Therefore, in order to meet the needs of casting production of auto parts, there is an urgent need for a mold preheating system and control method that can delay mold cracking, reduce mold deformation, uniform heating is conducive to temperature control, and is suitable for molds of different...
