How to choose good block machine mould

The mould is the most important parts of block machine. It affects the sizes of block, the shape of block and the strength of block. Good block machine mould can produce blocks with accurate sizes, beautiful shape and high strength.

The requirement of block machine mould:

1. high temperature performance

When the temperature of the block mold is high, the hardness and strength of mold will be decreased, which will cause early wear of the block mold. Therefore, the brick mold material should have high anti-tempering stability, so as to ensure that the brick mold has higher hardness and strength at working temperature.

2. cold and hot fatigue resistance

Some block molds are in a state of repeated heating and cooling during the working process, which causes the stress on the surface of the cavity to be pulled and the stress changes, causing cracking and flaking of the surface, increasing the frictional force, impeding the plastic deformation, and reducing the dimensional accuracy. As a result, block machine mold failure. Hot and cold fatigue is one of the main forms of mold failure in block making machine. So block machine mold should have high resistance to cold and heat fatigue.

3. wear resistance

When material degenerates in the mold cavity of the block machine, it flows and slides along the surface of the block mould, causing violent friction between the surface of the mold and the raw material, which causes the block machine mold to fail due to wear. Therefore, the wear resistance of materials is one of the most basic and important performances of block molds.

Hardness is the main factor affecting wear resistance. Under normal circumstances, the higher the hardness of the brick mold parts, the smaller the amount of wear and the better the wear resistance. In addition, wear resistance is also related to the type, number, morphology, size, and distribution of carbides in the material.

4. toughness

Most of the operating conditions of the brick molds are very harsh, and some often suffer from a large impact load, resulting in brittle fracture. In order to prevent the brick mold parts from suddenly breaking during work, the brick machine mold must have high strength and toughness.

The toughness of the brick mold depends mainly on the carbon content, grain size, and micro-structure of the material.

So How to choose good block machine mould?

1. Material-GiantLin use China Standard Steel Plate

Good block machine mould must be made of good steel plate to assure the hardness and strength of block mould.

2.       carburizing heat treatment

In order to increase the hardness and wear resistance of block machine mould, the mould must be adopted by carburizing heat treatment.

3. Welding: GiantLin Block Machine Factory adopt Carbon Dioxide Arc welding,

Advantages:

A: Steel shape no change after welding

B: High efficiency, no need remove welding rod

C: High strength

D: High crack resistance

4. Wire-Cutting Technology ensure accuracy of block size to be 99.9%
