Attention to precision mold accessory processing!

Attention to mold accessory processing!

1. Introduction to 2D and 3D rough machining of core inlay needles, non installation and non working plane machining (including safety platform surface, buffer installation surface, pressure plate surface, and side reference surface). Before semi precision machining, find the correct side reference surface to ensure accuracy.

2. Before precision machining, align the process reference hole reference surface, check the insert allowance, and inspect and recheck the machining accuracy. Precision machining of 2D and 3D surfaces, side punch surfaces and hole positions, Dongguan mold processing precision machining process reference holes and height references, precision machining guide surfaces and guide holes.

3. For important and difficult processing points, special emphasis should be placed on the process, and it is necessary to combine the processing points and express the process clearly. The process planning should be concise and expressed in detail, and the processing content should be expressed numerically as much as possible. When the inlay needs to be processed separately, pay attention to the process requirements for processing accuracy.

4. Precautions for mold accessory processing: For the embedded parts that need to be processed separately after combination processing, the benchmark requirements for process installation and separate processing should be met during combination processing. Springs are prone to damage during mold processing, so it is important to choose mold springs with long fatigue life.

In recent years, China's mold industry has grown rapidly at an average rate of over 15%, far exceeding the national GDP average value-added. Among them, casting molds account for about 5% of the total output value of various molds, with an annual growth rate of up to 25%. At present, China's automobile and motorcycle industry has entered a period of rapid growth, with production increasing significantly for several consecutive years. Especially the rapid growth of cars closely related to the foundry industry has increased the demand for complex and casting molds.
