Description
技术领域technical field
本发明涉及软磁磁芯安装领域，尤其涉及一种镶嵌软磁磁芯的制作方法。The invention relates to the field of soft magnetic core installation, in particular to a manufacturing method of an inlaid soft magnetic core.
背景技术Background technique
软磁磁芯是滤波器、电感器中的重要部件，在滤波器、电感器中的安放模式是将所生产的产品分成两半，目前软磁磁芯的装配模式主要是把成品分成两部分，将软磁磁芯用各种形式，装进后再合起来，如：点胶、灌封等。这样的形式会有整个产品开裂的风险，特别是有的产品应用在新能源汽车的变速箱内，如果产品开裂，将对变速箱或者传动机构造成很大的损害，甚至威胁整车的安全。Soft magnetic core is an important component in filters and inductors. The placement mode in filters and inductors is to divide the produced product into two halves. At present, the assembly mode of soft magnetic core mainly divides the finished product into two parts. , Put the soft magnetic core in various forms, put it in and then put it together, such as: dispensing, potting, etc. Such a form will have the risk of cracking the entire product, especially when some products are used in the gearbox of new energy vehicles. If the product cracks, it will cause great damage to the gearbox or transmission mechanism, and even threaten the safety of the entire vehicle.
发明内容SUMMARY OF THE INVENTION
根据以上技术问题，本发明提供一种镶嵌软磁磁芯的制作方法，其具体操作方法为：According to the above technical problems, the present invention provides a method for manufacturing an inlaid soft magnetic core, and the specific operation method is as follows:
首先，准备需要注塑的产品原料、模具和成品磁芯，并对其进行预处理，在注塑模具处设置预留型腔；First, prepare the raw materials, molds and finished magnetic cores that need to be injected, and preprocess them, and set up a reserved cavity at the injection mold;
然后，进行镶嵌，将相应的铜排或导线穿过磁芯同时放入注塑模具预留型腔内，再根据设定注塑温度及注塑时间，然后进行注塑；Then, inlay, put the corresponding copper bars or wires through the magnetic core and put them into the reserved cavity of the injection mold at the same time, and then perform injection molding according to the set injection temperature and injection time;
最后注塑完成后利用冷却模块进行冷却，冷却完毕后进行脱模。After the final injection is completed, the cooling module is used for cooling, and the mold is demolded after cooling.
镶嵌时把磁芯用护壳预先包覆起来。When inlaying, the magnetic core is pre-wrapped with a protective shell.
镶嵌时利用涂敷方式把磁芯预先包覆起来。When inlaying, the magnetic core is pre-coated by coating.
所述注塑温度260-390℃。The injection temperature is 260-390°C.
所述冷却时间5-15秒。The cooldown time is 5-15 seconds.
所述磁芯为软磁磁芯。The magnetic core is a soft magnetic core.
本发明的有益效果为：本发明改变现有磁芯的固定方式，将磁芯直接以“镶嵌件”形式在浇注成型过程中直接放在产品中，减少了缝隙和开裂风险。采用整体镶嵌工艺制作产品，几乎没有开裂的风险，以确保该产品对整车的安全风险降到最低。The beneficial effects of the present invention are as follows: the present invention changes the fixing method of the existing magnetic core, and directly places the magnetic core in the product in the form of an "inlay" during the casting molding process, thereby reducing the risk of gaps and cracks. The product is made by the whole inlay process, and there is almost no risk of cracking, so as to ensure that the safety risk of the product to the whole vehicle is minimized.
本发明软磁磁芯在镶嵌过程中要注意不能承受太大外应力，所以在镶嵌前会把磁芯用护壳或者涂敷等方式将磁芯预先包覆起来，以减少在镶嵌过程中对其软磁特性的影响，确保磁芯的正常使用。The soft magnetic core of the present invention should be careful not to withstand too much external stress during the inlaying process, so the magnetic core will be pre-wrapped by a protective shell or coating before inlaying, so as to reduce the damage to the magnetic core during the inlaying process. The influence of its soft magnetic properties ensures the normal use of the magnetic core.
本发明将软磁磁芯作为镶嵌件，在制作滤波器摸具整体成型过程中直接把磁芯镶嵌进去，出模后产品直接成型，不需要后来的其他工序。In the present invention, the soft magnetic core is used as an inlay, and the magnetic core is directly inlaid in the overall forming process of the filter mold.
