Description

一种铸造用型砂
技术领域
本发明涉及一种铸造领域，具体的说是一种铸造用型砂。
背景技术
砂型一般采用重力铸造，有特殊要求时也可采用低压铸造、离心铸造等工艺。砂型铸造的适应性很广，小件、大件，简单件、复杂件，单件、大批量都可采用。砂型铸造用的模具，以前多用木材制作，通称木模。木模缺点是易变形、易损坏；除单件生产的砂型铸件外，可以使用尺寸精度较高，并且使用寿命较长的铝合金模具或树脂模具。虽然价格有所提高，但仍比金属型铸造用的模具便宜得多，在小批量及大件生产中，价格优势尤为突出。此外，砂型比金属型耐火度更高，因而如铜合金和黑色金属等熔点较高的材料也多采用这种工艺。但是，砂型铸造也有一些不足之处：因为每个砂质铸型只能浇注一次，获得铸件后铸型即损坏，必须重新造型，所以砂型铸造的生产效率较低；又因为砂的整体性质软而多孔，所以砂型铸造的铸件尺寸精度较低，表面也较粗糙，在铸造过程中型砂的好坏直接影响铸造出来产品的好坏。
发明内容
为了缓解现有技术的不足和缺陷，本发明的目的在于提供一种铸造用型砂。
为了实现上述目的本发明采用如下技术方案：
一种铸造用型砂，其特征在于其组成原料的重量份为：回型砂30-40份、树脂60-85份、凹凸棒土10-15份、滑石粉4-8份、膨润土2-5份和石膏粉3-6份、水适量；以上材料通过均匀搅拌后即可得铸造用型砂。
本发明的有益效果：本发明制备方法简单，配方合理、成本低廉、可以广泛的运用于铸造领域。
