necessary adjustments before the mold is put into service."
Sentence patterns for mold usage and maintenance
Operating the mold
"When operating the mold, ensure that it is properly aligned and secured. Monitor the temperature and pressure during production runs."
Discussing mold design modifications
"After testing the mold, we've identified some areas that need to be modified for better part release. The ejector pins need to be adjusted and the gate location optimized."
Understanding mold design drawings
It is important to understand the purpose and function of each part of the mold, including the mold base, cavity, core, and other components. This helps in better understanding of the mold design and manufacturing process.

Lesson 1 What is Dies and Molds
Of the many manufacturing processes available for preparing molds only two are normally used in this case. These are (a)a direct machining operation on a rough steel forging or blank using the conventional machine tools, or (b)the “precision” investment casting technique in which a master pattern is made of the cavity and core.① The pattern is then used to prepare a casting of the cavity or core by a special process. A 4.25% nickel-chrome- molybdenum steel (BS 970-835 M30) is normally specified for integer mold plates which are to be made by the direct machining method. The precision investment casting method usually utilizes a high-chrome steel.

2.Basic Mold Construction （1）Operating Principle Basically the injection mold consists of two halves. One
mold half contains the sprue bushing and runner system， the other half houses the ejection system. The molded part is located at the parting line（ref. To DIN 16700）.
For ease of construction and to lower manufacturing cost， injection molds are becoming standardized. Some firms offer ready -made bases of square or round design as standard or stripper plate molds for immediate use. Only the inserts then have to be fitted into the bases.
