造型方法制造铸型(砂型和砂芯)的方法取决于三个主要条件,即模型与芯盒、型砂与芯砂和砂箱。在目前铸造生产中,模型芯盒、型砂芯砂和砂箱有许多种类,现分述如下:一、模型与芯盒模型与芯盒是造型的主要工艺装备。模型通常用木材、铸铝、铸铁、菱苦土及工程塑料等材料加工或精密铸造而成。它可分为整体模、劈模、车板和刮板等几种。1.整体模又称实样,一般做出 Modeling Methods The method of making the molds (sand and sand) depends on three main conditions, namely the model and core box, sand and core sand, and sand box. In the current casting production, there are many kinds of model core box, sand core sand box and sand box, are described as follows: First, the model and the core box model and the core box is the main form of technology and equipment. The model is usually made of wood, cast aluminum, cast iron, rhombic soil and engineering plastics and other materials or precision casting. It can be divided into the overall model, split mode, car plate and scraper several. 1. The overall model is also known, generally made
