What are the different types of molds?

   

 I. Mold classification:

Classification by hardness: soft mold and hard mold (quenching treatment). 

Classification by Grade Quality: Grade 1 Grade 3 by difficulty: Grade A B Class C Class D by mold size: super large medium small

II. Definition of mold hard die and soft mold:

1, mold hardness: soft mold, hard mode 1) Soft mold: mold steel has been pre-hard, no quenching treatment, but the hardness is low, HB below 400, the production life is less than 500,000 times, widely used.

2) hardened mold: the mold steel is annealed, divided into two rough machinings and finishing. After rough processing, the hardness is above HRC48 °. Keep the processing allowance of about 0.2. After rough processing, the tooling will have deformation to prevent the finishing can not meet the requirements. Production life is over 50 ~ 1 million times, with the most applications of small molds.

III. Mold quality grade: Grade I, Grade III, Grade I mold quality

1, mold: must be capable of one million or more opening times. This is the primary mold, the customer requires to make the best mold with the best materials and accessories.

 2. The requirements of Grade I mold are as follows:

(1) Detailed mold design (connecting the computer drawings and materials);

(2) Most mold embryo hardness

To have an HB280;

(3) The core shall be hardened by all HRC50, positions, and accessories;

(4) Medicare side division pipe jacking pin;

(5) line position must have wear-resistant pieces;

(6) temperature control monitor shall be installed in mold, brother, or position;

(7) It is recommended to make all the cooling water channels with nickel plating (ELECTROLESS NICKEL PLATING) intended to prevent rust and easy cleaning;

(8) The positioning lock shall be added to the mold line.
