The benefits of welding plastic mold components: 1. Welding metal structural parts saves materials compared to general riveting, and can also reduce weight, improve the carrying capacity of welded parts and reduce energy loss. 2. The welding method is relatively flexible and can effectively simplify the manufacturing process of complex parts and large parts, increase processing speed, shorten working time, and reduce production time.
Classification of Injection Mold EDM Machine Tools: Slow-feed wire cutting machine tools, the electrode wire is made of copper wire and moves in one direction at a low speed. The main method is to continuously supply the electrode wire, which is replenished after the electrode is worn out. The processing quality is good, the work is relatively stable and uniform, the jitter amplitude is small, and the production efficiency is relatively high. It is suitable for processing workpieces with high precision requirements, roundness and linear dimensions.
In order to improve the precision of the parts, it is necessary to cut during the injection mold processing. So what are the cutting technologies related to injection molds? 1. Micro-wire cutting technology is mainly used for small parts that are difficult to process in large machinery. The electrode wire is a relatively small tungsten wire. The discharge energy is weak during processing, which has extremely high requirements for the pulse control system and machine tool accuracy.
Wire EDM is a processing technology for injection molds that can control and adjust the size of workpieces. Reasonable wire EDM processing technology can effectively ensure the quality of workpieces and the performance of molds. The analysis and review of drawings is an important step, and it is the key to the processing quality and comprehensive technical indicators of workpieces. The first thing to do is to pick out workpieces that cannot be processed or are difficult to process. What are they?
The surface treatment of injection molds plays a key role in mold quality. Although mold surface technology is constantly developing and many new technologies have been produced, there are still many mold manufacturers who use flame quenching technology to treat the mold surface. What are the advantages of flame quenching technology? Flame surface quenching generally uses acetylene and oxygen to moderate the burning flame and spray it onto the surface of the part. The part is quickly heated.
Pulse technology is an emerging injection mold surface technology. With the progress of my country's industrialization, pulse technology has developed rapidly, and people have gradually begun to pay attention to its unique advantages. The processing method of pulse technology has the characteristics of automation, high efficiency, energy saving and environmental protection. The development of its technology is conducive to the improvement of the level of mold processing and use. So what are the advantages of applying pulse technology to mold surface?
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?
