冷芯盒模具使用树脂砂作原料，用三乙胺固化。也有用水玻璃砂作原料，用二氧化碳固化的，水玻璃砂的流动性差，只能用在简单产品工艺上，因此现在使用的非常少。使用树脂砂作原料成本比覆膜砂要低，而且产品效率高，所以在大的砂型产品当中被广泛应用。
The cold box mold is made of resin sand and cured with three ethylamine. There are also water glass sand as raw materials, carbon dioxide solidified, water glass sand fluidity is poor, can only be used in the simple product process, so the use of very few. The cost of resin sand is lower than that of coated sand, and its efficiency is high, so it is widely used in large sand products.
冷芯盒模具的射砂孔比较大，一般都在10mm-30mm之间，这样有利于成型，射砂时消耗的气量也比较大，所以排气孔也比较和多，有利于气体流畅才能保证产品的成功率。冷芯盒模具适合体积比较大质量比较高的产品。
Cold core box mold sand holes are relatively large, generally in the 10mm-30mm, which is conducive to molding, sand consumption when the amount of gas is also relatively large, so the exhaust holes are also more, in favor of gas flow to ensure the success rate of the product. Cold box mold is suitable for products with relatively large volume and high quality.
冷芯盒模具用的射芯机又叫做冷芯盒射芯机，也称为冷芯机。模具不需要加热就可以把产品固化成型，所以人们就叫它冷芯盒模具。模具是通过加热的方式来固化砂芯产品，现在都是采用电加热的方法，以前也有用煤气等明火在外面直接烧的，因温度不好控制，产品成功率较低，现在很少有人用这种方法。
The core shooter used for cold box mold is also called cold box core shooting machine, also known as cold core machine. Mold can be cured without heating, so people call it cold core box mold. The mold is heated by the way to solidify the sand core products, now is the use of electric heating method, before the use of gas and other open fire directly on the outside, because the temperature is not well controlled, the product success rate is low, now few people use this method.
射芯机厂家提醒您：射芯机的电气系统需要经常检查，一般要2-3昆山模具设计培训学校星期检查一次为宜，检查是否有异声、松动、变色、发热、焦味等，接有电线的螺丝每次要紧一遍，特别是主电路和大电流的线路和元件，以免松动后虚连烧坏电气元件和线路，造成严重损失。
The core maker reminds you that the electrical system of the core machine needs to be checked regularly. Generally, the 2-3 Kunshan mold design and training school will check once a week to check whether there is any sound, loosening, discoloration, fever, coke, etc., each time the screws are connected to the wire, especially the main circuit and the large current lines and components. So as to avoid loosening the electrical components and circuits, resulting in serious losses.
