Problems solved by technology

However, in addition to some of their own advantages, wooden molds and metal molds also have some disadvantages that cannot be ignored.
[0003] For example, wooden molds, in the process of making wooden molds, will produce a lot of dust and pollute the environment, and the mechanical strength of wooden molds is low, the surface hardness is not high, and the service life is low
During the repeated use of the mold, wear and tear will inevitably occur. After a certain period of use, the damaged parts of the wooden mold must be repaired and maintained, which increases the cost of the mold and is not conducive to continuous operation on site. Therefore, the wooden mold Not suitable for mass production on site
When the temperature and humidity change, the size of the wooden mold changes, which will affect the dimensional accuracy of the casting
For example, metal molds have good surface strength, high dimensional accuracy, and long service life, but the cost of a single mold is high, the equipment is complicated, and the skill level of workers is high.

Description

technical field [0001] The invention belongs to the field of mold making, and in particular relates to a novel two-component mold making material and a preparation method thereof. Background technique [0002] At present, the sand casting industry mainly uses two kinds of molds, wooden molds and metal molds, to make sand molds of the desired shape. The production of wooden molds and metal molds is a traditional "hard" physical molding method, which is to cut, process, polish wood materials or metal materials, and then assemble them to form a complete mold. However, in addition to some of their own advantages, wooden molds and metal molds also have some disadvantages that cannot be ignored. [0003] For example, wooden molds, in the process of making wooden molds, will produce a lot of dust and pollute the environment, and the mechanical strength of wooden molds is low, the surface hardness is not high, and the service life is low. During the repeated use of the mold, wear ...
