Pole ear mold is a widely used mold that plays a very important role in industrial production. The processing and manufacturing of polar ear molds have a decisive impact on the production and quality of products. Therefore, this article will conduct a detailed analysis around the processing and manufacturing of polar ear molds.
1、 Concept of polar ear mold
Pole ear mold is a commonly used mold type, which is usually used to make various parts of different shapes. The characteristic of this mold is the formation of a pair of lugs on the shape of the mold, called "pole lugs", to facilitate the removal of the mold. Pole ear molds can be divided into various types such as die-casting molds, injection molds, extrusion molds, etc., and are widely used in various fields such as automotive manufacturing, electronics, communication, electrical appliances, lighting fixtures, postal and telecommunications, home furnishings, etc.
2、 The processing and manufacturing process of the polar ear mold
1. Design and production
The processing and manufacturing of the polar ear mold first requires design and production. Designers need to design based on the size, shape, and other characteristics of the products they need to produce. Then, design a 3D drawing, cut and assemble it into geometrically consistent parent parts based on the 3D drawing, and then write a program for processing. After the design is completed, it is necessary to review and confirm the design plan. After confirmation, a sample will be made before production to check the correctness of the design.
2. Processing and manufacturing
Processing and manufacturing are the core links in the manufacturing of polar ear molds. Processing and manufacturing include vertical milling, rough machining, precision machining, electric discharge machining, grinding and polishing, and other links. Vertical milling is the process of processing the tenon structure of the mother component. For the pole ear mold, it is necessary to machine a shape suitable for the characteristics of the pole ear on the mother component. Rough machining is the use of rough machining equipment such as lathes to perform large-scale cutting on molds. Precision machining is a technology that uses cutting tools to perform precise cutting of materials, completing the machining of molds by repeatedly grinding and cutting, and proofreading dimensions. Electric discharge machining is the use of the principle of electric discharge to release charges onto the surface of a workpiece, causing strong corrosion and dissolving the material on the surface of the workpiece. In this process, the workpiece will not deform and the machining accuracy is very high. Grinding and polishing is the process of grinding and polishing the surface of a mold after processing to meet the requirements of smoothness and brightness, while also ensuring surface quality.
3. Injection molding
Injection molding refers to the use of an injection molding machine to inject molten plastic into the polar ear mold, solidify it, and then remove its finished product. In the process of manufacturing pole ear molds, different materials of plastic have different requirements for the molds. Mold heating and mold temperature control are very important. If the mold temperature is not appropriate, it may lead to a decrease in product quality or damage to the mold.
4. Assembly and debugging
After the processing of the polar ear mold is completed, the producer needs to assemble and debug the mold. Test whether the pole ear mold can work properly, while identifying deficiencies and defects during the process, and make adjustments and improvements.
3、 Key technical points in the processing and manufacturing of polar ear molds
1. Precision processing
The requirement of the polar ear mold itself is to process products with extra precision. Each processing step is required to be as precise as possible to improve its own accuracy in the processing process, so as to ensure that the processed mold can correspond to the requirements and standards of different products.
2. Reasonably handle materials
The main material for the production of pole ear molds is metal, and material selection and treatment are very important. Generally speaking, in terms of materials, advanced steel, alloy steel, and other materials can be selected, which have good mechanical properties, wear resistance, and other aspects. However, in the selection of steel, one must not overly pursue hardness while neglecting the toughness of the steel. Only by simultaneously considering these indicators can the service life of the mold be guaranteed and investment costs be reduced.
3. Control temperature
When performing injection molding for the polar ear mold, precise control of mold heating and mold temperature is required. This control is very important, as improper temperature control can lead to damage to the product and mold. At the same time, maintaining a good temperature balance also has a crucial impact on the quality of the products produced.
4、 Quality control of the machining and manufacturing of polar ear molds
1.Strict quality control process
The processing and manufacturing of polar ear molds need to consider every aspect of the manufacturing process, from design, selection of mold materials, processing, testing, to assembly and debugging, each step needs to be tightly controlled.
2. Processing equipment specifications
For each step of the manufacturing process of the polar ear mold, different processing equipment is required, so whether it is design or manufacturing, it is necessary to ensure the standardization of equipment operation.
3. Complete quality inspection plan
The quality inspection plan for the pole ear mold must be implemented. It can detect and handle problems such as damage, dimensional deviation, and threading in a timely manner during the processing process based on established inspection standards.
5、 Conclusion
The manufacturing process of the polar ear mold is very complicated, and it is necessary to consider the requirements of each link. But only by ensuring that every detail is achieved with precision can we produce pole ear molds with excellent quality and stable performance, thereby contributing to the progress of industrial production.
