冷芯盒模具使用樹脂砂作原料，用三乙胺固化。也有用水玻璃砂作原料，用二氧化碳固化的，水玻璃砂的流動(dòng)性差，只能用在簡(jiǎn)單產(chǎn)品工藝上，因此現(xiàn)在使用的非常少。使用樹脂砂作原料成本比覆膜砂要低，而且產(chǎn)品效率高，所以在大的砂型產(chǎn)品當(dāng)中被廣泛應(yīng)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較大，一般都在10mm-30mm之間，這樣有利于成型，射砂時(shí)消耗的氣量也比較大，所以排氣孔也比較和多，有利于氣體流暢才能保證產(chǎn)品的成功率。冷芯盒模具適合體積比較大質(zhì)量比較高的產(chǎn)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機(jī)又叫做冷芯盒射芯機(jī)，也稱為冷芯機(jī)。模具不需要加熱就可以把產(chǎn)品固化成型，所以人們就叫它冷芯盒模具。模具是通過加熱的方式來(lái)固化砂芯產(chǎn)品，現(xiàn)在都是采用電加熱的方法，以前也有用煤氣等明火在外面直接燒的，因溫度不好控制，產(chǎn)品成功率較低，現(xiàn)在很少有人用這種方法。
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.
射芯機(jī)廠家提醒您：射芯機(jī)的電氣系統(tǒng)需要經(jīng)常檢查，一般要2-3昆山模具設(shè)計(jì)培訓(xùn)學(xué)校星期檢查一次為宜，檢查是否有異聲、松動(dòng)、變色、發(fā)熱、焦味等，接有電線的螺絲每次要緊一遍，特別是主電路和大電流的線路和元件，以免松動(dòng)后虛連燒壞電氣元件和線路，造成嚴(yán)重?fù)p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.
