The manufacturing process of injection molds is generally very complicated, and whether the quality of the mold is good and meets the requirements has an important impact on the parts processed by injection molding. The reasonable matching of the internal accessories of the mold can ensure the stable operation. In addition, the surface treatment of the mold is also very important. At present, the mold surface treatment technology has developed to a certain extent and is increasingly concerned and promoted.
Cold extrusion die is a common heat treatment method. Plastic molds processed in this way must have high strength and excellent wear resistance, because during cold extrusion, the metal will be subjected to uneven pressure in three directions, and a certain degree of deformation will occur. A mold with good performance can withstand repeated strong pressure without being damaged, and at the same time, it must have the ability to resist small plastic deformation, so as to ensure that the mold remains stable under strong cold extrusion.
Injection molds are essential tools for molding parts. The quality of mold manufacturing will directly affect the appearance, performance and use requirements of molded parts. The materials needed for mold manufacturing are very important. So what factors should be considered when choosing injection mold materials? 1. The working conditions of the mold, the size of the bearing capacity and impact during the processing, the processing environment and the working temperature,
The manufacturing of plastic molds is extremely complex, and with the advancement of current industrial technology, it is important to improve production efficiency and reduce the loss of parts and materials. The current mold forming technology is widely used in the automotive, household goods, digital electronics and other industries. Whether the mold material has good performance determines the length of the mold life, as well as the appearance quality and production efficiency of the molded parts. Change the environment for different working conditions
The exhaust groove is an important part of the plastic mold design. It can discharge the excess gas generated in the mold. It prevents the gas from hindering the normal filling speed of the plastic melt and prevents the gas compression from generating excess heat that causes the part to burn. 1. In order to facilitate the manufacture and cleaning of the mold, the exhaust groove should be set on the concave mold side of the parting surface as much as possible.
As the most critical part of the plastic mold gating system, the type and layout of the gate plays an important role in the molding of the finished product and will also affect the overall quality of the product. In most cases, the gate is the smallest part in the entire gating system, except for the direct gate of the main runner type. So, what should be paid attention to in the layout of the gate? Two-hole part on the part
The pouring system is the flow channel of the plastic mold from the injection molding machine nozzle to the cavity entrance. It can be divided into ordinary runner pouring system and non-runner pouring system. It is an indispensable part of the molding process. Therefore, the pouring system must be well designed and certain principles must be followed during the design. 1. In order to facilitate the molten plastic to fill each cavity in the mold evenly, the arrangement of the mold cavity should be flat.
The water channel is an important part of the plastic mold. The design of the water channel affects the molding and appearance quality of the product. If the water channel is not designed well, it will cause scale to form during long-term processing, making the injection molding machine oil temperature too high, the system pressure unstable, and unable to form a good water circulation, causing the processing to be suspended. Therefore, certain principles must be followed in the design of the water channel. 1. Heat transfer that meets cooling needs
The existence of the draft angle is to make it easier for the part to be ejected from the plastic mold. Without the draft angle, the part cannot be ejected easily and is easily damaged and becomes a defective product. If the draft angle is not set, the overall design of the mold must be relatively complicated. An overly complicated mold design is not conducive to processing and is likely to increase the resources lost in mold manufacturing. Therefore, the existence of the draft angle is very necessary. So what are the requirements for the design of the draft angle?
一般来说，塑胶模具中的斜导柱抽芯机构的设计是方便制件更加顺利的从模具脱离，导柱抽芯机构是由和开模方向成一定角度的斜导柱跟滑块组成。为了让制件脱模并且在合模之后能够顺利复位，保证抽芯动作的平稳顺藏就需要有滑块定位和闭锁装置。那么斜导柱抽芯机构的设计原则是什么？ &
一个完整的制件成型之后需要从塑胶模具脱出，这个脱模过程是需推出机构，或者叫顶出机构的协助。将制件推出时要保证推出结构的正常运作，只有推出动作顺畅无阻碍，最后成型的才会是优质制件，那么模具的推出机构有哪几类，又有什么特点？ 推出机构一般是由推出、复位和导向零
塑胶模具的设计是比较复杂的，涉及到塑胶模具内各个零部件，主要结构的位置、尺寸精度、注塑设备的塑化能力和性能，原料的流动性等。为了保证所制造的模具质量，需要对关键部分检查，那么需要进行校对的内容具体有哪些呢？ 一、检查模具零件的强度、尺寸精度、结构
塑料在注塑成型过程中通过高压进入塑胶模具当中，若是制品的形状过于复杂，设计的壁厚不均就会在固化的时候受温度影响，产生过多的应力导致制品的外观和尺寸精度出现问题。而控制好温度经过冷却的制品，外观没有明显缺陷、尺寸稳定，有着较高的机械强度，符合客户的要求。因此冷却系统成为塑胶模
塑胶模具在生产过程中离不开和温度的接触，除了加热系统之外，冷却系统的存在也十分重要，注塑产品在刚刚充模的时候就已经开始了冷却。冷却系统主要由冷却水道、模具温度控制器和加热组件等组成，冷却系统对已产品质量、生产成本有着重要的作用。 一、塑料需要合
镶针是塑胶模具上的一个配件，是将产品从模具分离最常用的方法。在产品注塑过程中压铸模具模芯时是比较容易出现意外的，当意外发生以后只要将有问题的镶针取出并更换就可以解决，避免了模具报废的可能，在一定程度上可以节省制造成本。那么镶针在塑胶模具当中扮演着什么样的角色，具体作用有
