Description

Ceramic body injection molding machine

technical field

The utility model relates to the technical field of ceramic body injection molding, in particular to a ceramic body injection molding machine.

Background technique

The production of special ceramics in my country started in the 1950s. The main technological process is: powder making → mixing of paraffin or adhesive → molding → removal of paraffin or adhesive → sintering into porcelain and other processes. Forming is the most important part of the whole process. Today, 80% of the special ceramic molding process is still using the hot press grouting molding process in the 1950s. The long-term application shows that the product has the disadvantages of easy deformation in terms of quality, poor product structure density, poor compressive strength, tensile strength, and flexural strength, and unsatisfactory electrical insulation and voltage resistance performance, so the product qualification rate is not high.

In order to improve this situation, enterprises, experts and scholars continue to explore new blank forming processes. Therefore, the dry-pressed ceramic powder molding machine came into being. After nearly 20 years of use, the ceramic body produced by the dry-pressed molding machine is limited to products with relatively simple geometric shapes, and it is far from meeting the needs of special ceramics with various shapes. And there is a fatal weakness, that is, the internal stress distribution of the fired product is not uniform, and the compressive strength varies greatly from place to place. For example, there are defects such as low density at the waist of cylindrical products, cracks in the angular position of special-shaped products, etc., resulting in frequent damage and scrapping of products during the user's assembly process.

The ceramic body injection molding technology that has been produced successively has also come out for many years at home and abroad. The product use has proved that the quality of the products produced by it is better than that of hot-pressed grouting molding and powder dry-pressed molding products. The product has no geometric shape restrictions, and the density and internal stress of the ceramic body are uniform; after the test, no matter what shape the product is, the density, mechanical compression, and tensile strength of the porcelain body are uniform everywhere, and there is no reason for the ceramic body The anisotropy caused by the internal shrinkage residual stress of the ceramic produced by uneven density. At the same time, the voltage resistance performance of electrical insulation has been greatly improved, and the product surface is smooth and non-deformable, which is well received by customers. However, due to equipment problems, the production efficiency and product cost cannot achieve the desired results, and it is easy to cause damage to the product during cutting, making it difficult to fully implement. Many manufacturers even have to give up using this equipment. The utility model has solved this difficult problem effectively.
