Characteristics of several different ceramic mold structures

Sep 29, 2018

After years of design practice, it is found that the structure of the designed ceramic mold is reasonable and easy to use. It is crucial to be able to produce qualified workpieces and to develop new products. A set of ceramic molds, simple structure but dozens of parts, but must not be underestimated.


At the beginning of the design, what kind of mold structure is selected, whether it is the choice of the formal mold structure or the flip mold structure; whether it is the single-process mold structure or the composite mold structure. In order to understand this problem, it is necessary to have a full and in-depth understanding of each ceramic mold structure.



The structural feature of the formal ceramic mold is that the concave mold is mounted on the lower mold base, so whether the workpiece is blanked, punched, or other processes, the workpiece or waste can be conveniently placed into the waste hole on the punching table. Therefore, when designing a dressing mold, it is not necessary to consider the flow direction of the workpiece or waste. Therefore, the designed mold structure is very simple and very practical.


Therefore, when designing ceramic molds, the design principle that should be followed is that the formal mold structure should be preferred. Only when the technical requirements of the workpiece can be met under the formal mold structure, other forms of mold structure can be considered, such as flip-chip mold, its structural feature is that the punch is mounted on the lower mold base, so it is necessary to use the elastic discharge device. Remove the workpiece or waste from the punch.


The so-called single-process ceramic mold structure can only complete one process, so the ceramic mold has simple structure, short manufacturing cycle and low processing cost; and the mold has good versatility, and is suitable for small and medium-sized workpieces without being restricted by the size of the stamping part. Production; also suitable for the production of some ceramic products with large size and thick thickness.


The composite ceramic mold structure can complete two or more processes, so there is no cumulative positioning error, and it is suitable for making thin materials and brittle or soft materials; and the production efficiency is high, the mold structure is compact, and the area is small. In short, when we choose the ceramic mold structure, we should weigh the pros and cons according to the structure of various molds and consider them comprehensively.
