Embodiment Construction

[0026] (1) Place the formed white mold on the rotary tray of an industrial microwave oven, close the oven door, and bake for 3-10 minutes. Dry the moisture of the white mold so that the white mold does not deform or shrink;

[0027] (2) Dip-coat the white mold dried in the previous step, and place it on an inclined shelf for 3-5 minutes, allowing the paint to flow until it does not accumulate in large quantities;

[0028] (3) Place the white mold dipped in the first coating on the rotary tray of the microwave oven, close the oven door, and bake for 10-18 minutes. The power of the microwave emission device is 2-4KW / h, and the oven temperature is 50 -60°C, dry the first layer of paint thoroughly, and keep the white mold from deforming or shrinking;

[0029] (4) The above steps (2) and (3) will be repeated twice;

[0030] (5) Place the fully dried white mold that has been dipped and coated three times in the drying room and wait for pouring.

[0031] The equipment for microwav...

Abstract

The invention discloses a method and equipment for drying a white pattern through microwave in evaporable pattern casting. The method adopts microwave equipment for drying the white pattern brushed with coating for three times, the white pattern is heated uniformly, the outer-layer coating of the white pattern is ensured to be dried, and the white pattern does not deform or shrink due to microwave heating, therefore, the drying efficiency of the white pattern coating can be greatly improved, the batch production of products is realized, a coal-fired boiler is not needed to supply steam, the electro-thermal conversion efficiency is high, the energy is saved, and the environment is protected. Meanwhile, the labor cost of enterprises is reduced, the economic benefits of the enterprises are improved, and the invention is particularly applicable to white pattern drying in the evaporable pattern casting.

Description

technical field [0001] The invention belongs to the field of drying of white mold coatings for lost foam casting, and specifically relates to a technology for applying microwave drying materials to drying of white mold coatings for lost foam casting and equipment thereof. Background technique [0002] Lost foam casting (lost foam casting, also known as solid casting, is to bond and combine foam models similar in size and shape to castings to form a model cluster. After brushing refractory paint and drying, it is buried in dry quartz sand for vibration molding. Pressing and pouring, the model is vaporized, the liquid metal occupies the position of the model, and solidifies and cools to form a new casting method) technology, as the "green casting technology" of the 21st century, because it belongs to the green casting mode, the production is clean and fast, and the product quality Good quality, low production cost, suitable for mass production of castings and the production of...
