Two-color mold maintenance and maintenance:

1: The two-color mold must be cleaned and grinded after a long time, and the edge surface must be demagnetized after grinding, and it cannot be magnetic, otherwise it is easy to block material.
2: The spring and other elastic parts of the two-color mold are the most easily damaged during the use of the spring, usually breaking and deformation. The way to take is to replace, in the replacement process must pay attention to the specifications and models of the spring, the specifications and the spring

The model is confirmed by color, outside diameter and length, and can only be replaced if all three are the same.
3: The punch is prone to break, bend and chew during the use of the two-color mold, and the punch sleeve is generally chewed. Punch and punch sleeve damage are generally replaced with the same specification parts. The parameters of the punch mainly have working parts

Dimensions, mounting part dimensions, length dimensions, etc.
4: The fastening parts of the two-color mold, check whether the fastening parts are loose and damaged, and the way to take is to find parts of the same specification for replacement.
5: The press parts of the two-color mold such as the press plate, the good force glue, etc., the discharge parts such as the stripper plate, the pneumatic top material, etc. During maintenance, check the relationship between the parts and whether there is damage, repair the damaged part, and check whether there is leakage

Gas phenomenon, and take measures for specific situations.

The two-color mold meets the requirements of working conditions:

1, wear resistance of two-color mold: hardness is the main factor affecting wear resistance. In addition, the wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material.

2, the strength and toughness of the two-color mold: the toughness of the two-color mold mainly depends on the carbon content of the material, grain size and organizational state.

3, fatigue fracture performance: the fatigue fracture performance of the two-color mold mainly depends on its strength, toughness, hardness, and the content of inclusions in the material.

4, high temperature performance: the two-color mold material should have a high tempering stability to ensure that the mold has a high hardness and strength at the working temperature.

5, cold and heat fatigue resistance: cold and heat fatigue is one of the main forms of hot work mold failure, this type of mold should have high cold and heat fatigue resistance.

6, corrosion resistance: Some two-color molds such as plastic molds at work, due to the presence of chlorine, fluorine and other elements in the plastic, after heat decomposition and precipitation of HCI, HF and other strong corrosive gases, erosion of the mold cavity surface, increase its surface roughness, aggravate wear failure.
