What Are The Specific Requirements For Casting Mould Processing

Taizhou Huangyan Master Mold Co.,Ltd | Updated: Apr 24, 2018

There are many kinds of casting mould, such as alloy mould, sheet metal mould, plastic mould, stamping mould, casting mould, extrusion mould and pressure.

Casting mould, other mould, mould material. The casting mould is described below.

The casting mould is to obtain the structure shape of the part, in advance with other easily formed material to make the structural appearance of the part, then in.

In the sand mold, the mold is put into the mold, and a cavity is formed in the sand mold, which is the same size as the part structure. In this cavity, the liquid liquid is poured.

The liquid can then be cooled and solidified to form exactly the same parts as the mold. It can also be used on the molding machine, and can be used in any.

Mold machinery above.

The technical requirements of the parts affect the working performance of the parts, and on the other hand, it is directly related to the economy and feasibility of the manufacturing process.

. Generally speaking, in the process of processing, with the improvement of machining surface precision, it is inevitable to get a finer surface roughness at the same time, but with the following.

The surface roughness is worth decreasing, and the processing cost should be increased. Therefore, when determining the accuracy, the operator must first ensure the performance requirements of the parts.

Also consider the process condition and the manufacturing cost of parts and so on many factors. In order to ensure the manufacturing quality and precision of casting mould, in die parts.

During processing, the following technical requirements shall be made to meet the design requirements of the parts:

1. Precision of machining shape of parts.

2. Other special requirements.

3. The position accuracy of each machining surface of the parts.

4. Precision of machining surface dimension of parts.

5. Hardness and heat treatment requirements of parts.

6. Surface roughness of parts.

In order to shorten the mould cycle and improve the market competition, the die enterprises adopt high speed machining technology. HSM is generally used primarily.

Large and medium-sized mould processing, such as auto cover mould, die casting mould, large plastic mould and other surface processing, its surface machining accuracy can reach 0.01mm.

. Using nc high speed milling technology in production can shorten the molding time greatly. After high speed milling, the mold surface is only needed to be tossed.

Light can be used, saving a lot of grinding and polishing time. Increasing CNC high-speed milling machine is one of the key points of equipment investment in die enterprise.

In general, the material of casting mould is relatively large, and we can choose plastic according to the actual requirements of customers and production.

Materials such as aluminum alloy, steel and steel or wood. The application of plastic mould is increasing, especially to the market and plastic mold.

Increased longevity. Aluminum alloy mold is characterized by light weight and high precision. But the application is not widespread. Cast iron is still in large quantities.

Casting production is preferred because it has many advantages such as high strength, wear-resisting, easy to process, low cost and long life. Steel was mainly used before.

The standard parts, wear-resistant inserts or lining on the mold are seldom used to make the casting mould body, because carbon steel has a longer life than the ball iron or low alloy ash.

Iron is low, and alloy steel is very expensive. Wood model is widely used in manual modeling or single small batch production.

The speed of desertification is accelerating, so this approach is not sustainable. Instead, it is solid casting. Solid casting

Foam plastic sheets are made of materials, cut and glued together, and then cast into castings. The method is compared with wood model, and the precision of casting is higher.

And better surface roughness.
