During the mold manufacturing process, we usually encounter some problems, such as the cup lid cannot be covered easily. At this time, we need to design a chamfer for the mouth of the cup lid so that it can be covered easily and the sealing is also improved.

Mold chamfering refers to the process of tilting and cutting some corners of the mold to improve the strength and durability of the mold, while reducing surface defects and damage to the product during processing. The main functions of mold chamfering are as follows:

1. Improve the durability of the mold: mold chamfering can reduce the wear and fatigue of the mold during use, thereby extending the service life of the mold.

2. Reduce product surface defects: mold chamfering can avoid surface defects such as burrs and scratches during the processing of the product, thereby improving the quality of the product.

3. Reduce processing difficulty and cost: mold chamfering can reduce the processing difficulty and cost of the product, while reducing the wear of the tool during the processing and improving the processing efficiency.

There are many ways to chamfer the mold, such as manual grinding, mechanical cutting and EDM. Regardless of the method used, the chamfering requirements should meet the following points:

1. The original size and precision of the mold should be maintained after chamfering.

2. The angle and radius of the chamfer should meet the requirements of the product and should not affect the design and appearance of the product.

3. The position of the chamfer should be reasonable to avoid affecting the function and use of the product.

4. The chamfered surface should be smooth and flat, and there should be no surface defects such as burrs and scratches.

Mold chamfering is a technology often used in industrial production. Here are some typical application cases:

1. Automobile wheel hub mold: Chamfering some key parts of automobile wheel hub mold can effectively improve the service life of the mold and the quality of the product.

2. Electronic product mold: Chamfering some ink lines of electronic product mold can reduce surface defects and damage of the product during processing and improve the appearance and quality of the product.

3. Home appliance mold: Chamfering some bends of home appliance mold can avoid damage and deformation of the product during processing and improve the service life and quality of the product.
