Description

一种用于高压铸造的模具浇道A mold runner for high pressure casting 技术领域technical field

本实用新型涉及模具生产设备领域，尤其涉及一种用于高压铸造的模具浇道。The utility model relates to the field of mold production equipment, in particular to a mold runner for high-pressure casting.

背景技术Background technique

铸造是人类掌握比较早的一种金属热加工工艺，铸造是将液体金属浇铸到与零件形状相适应的铸造空腔中，待其冷却凝固后，以获得零件或毛坯的方法，被铸物质多为原为固态但加热至液态的金属，而铸模的材料可以是砂、金属甚至陶瓷，因应不同要求，使用的方法也会有所不同。Casting is a kind of metal thermal processing technology that humans have mastered earlier. Casting is a method of casting liquid metal into a casting cavity suitable for the shape of the part, and after it cools and solidifies to obtain parts or blanks. It is a metal that is originally solid but heated to a liquid state, and the material of the mold can be sand, metal or even ceramic, and the method used will be different according to different requirements.

高压铸造，很多时候被简称为压力铸造，它是将金属液倒入压室，使金属液在高速下填充模具型腔后在高压下结晶凝固形成铸件的过程，高压、高速是高压铸造的主要特点，填充时的流动速度可到30-80mm/s，甚至更高，金属液凝固时承受的压力高达40-120MPa，金属液填充型腔的时间极短，具有表面光洁度好，尺寸稳定、可直接成型薄壁结构等优点。High pressure casting, often referred to as pressure casting, is the process of pouring molten metal into the pressure chamber, so that the molten metal fills the mold cavity at high speed and then crystallizes and solidifies under high pressure to form a casting. High pressure and high speed are the main processes of high pressure casting Features, the flow speed during filling can reach 30-80mm/s, or even higher, the pressure when the molten metal solidifies is as high as 40-120MPa, the time for the molten metal to fill the cavity is extremely short, and it has good surface finish, dimensional stability, and flexibility. The advantages of direct molding of thin-walled structures, etc.

随着我国汽车等相关产业的兴起，铸造模具产业也被带动起来，我国铸造行业发展迅速，前景非常可观，但是其在发展过程中仍然面临很多瓶颈，缺乏技术的创新，技术创新是通过在铸造行业内不断摸索和经验的积累，来实现和确保大型精密复杂的铸件质量。With the rise of my country's automobile and other related industries, the foundry mold industry has also been driven. my country's foundry industry has developed rapidly and has very promising prospects, but it still faces many bottlenecks in the development process and lacks technological innovation. The continuous exploration and accumulation of experience in the industry can realize and ensure the quality of large, precise and complex castings.

铸件产品的好坏，一方面取决于磨具制作的精度，但是，最重要的因素是模具的前期设计，也就是对模具的浇注系统的设计，若一套 模具的设计方案存在问题，甚至是不佳，都会直接影响到铸件的外观，比如：欠铸、冷纹、收缩、砂孔、变形等成型状况不良问题出现。On the one hand, the quality of casting products depends on the precision of the mold making, but the most important factor is the early design of the mold, that is, the design of the pouring system of the mold. If it is not good, it will directly affect the appearance of the casting, such as: under-casting, cold streaks, shrinkage, sand holes, deformation and other poor forming conditions.

模具的设计技术是通过对现场熟悉压铸机械设备、撑握压铸技术以及浇注系统学习与计算的过程，模具设计的合理性，是铸件的结构决定的，同时与现场压铸设备性能和压铸人员的技术相匹配。The mold design technology is the process of learning and calculating through the familiarity of the die-casting machinery and equipment, support die-casting technology and gating system on site. The rationality of the mold design is determined by the structure of the casting, and at the same time, it is related to the performance of the on-site die-casting equipment and the technology of the die-casting personnel. match.

压铸模具的浇道系统是金属液从压射室流到型腔的分流通道，浇道系统的好坏，对铸件的质量和生产效益都有非常重要的影响，目前市场上所使用的高压铸造的模具浇道，一般都是采用从中间填充，填充方式比较单一，在使用过程中仍存在不足，压铸出来的铸件常常会出现譬如欠铸、冷纹、收缩、砂孔、变形等成型问题，因此，为了解决此类问题，我们提出了一种用于高压铸造的模具浇道。The sprue system of the die-casting mold is the shunt channel for the molten metal to flow from the injection chamber to the cavity. The quality of the sprue system has a very important impact on the quality and production efficiency of the castings. The high-pressure casting currently used in the market The sprue of the mold is generally filled from the middle, and the filling method is relatively simple. There are still deficiencies in the process of use. The die-cast castings often have forming problems such as under-casting, cold streaks, shrinkage, sand holes, and deformation. Therefore, to solve such problems, we propose a mold runner for high pressure casting.
