Problems solved by technology

On the one hand, this method is limited by the mold making, and on the other hand, it is limited by the difficulty in positioning the mold in the double-sided cavity, and it is difficult to ensure the accuracy of the mold position for complex cavities.
Whether it is processing metal blocks or silicone rubber plugs, it is time-consuming and labor-intensive, and after processing, it can only be used for the molding of specific cavity shapes, which is not universal
The production of silicone rubber plugs is relatively simple, and the cost is low, but the processing precision of silicone rubber plugs is not high, and it is easy to deform after several times of use, which cannot guarantee the precision requirements of fine mass production for mold precision

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] as attached figure 1 Shown, a kind of multilayer ceramic double-sided complex cavity structure molding method, it comprises the following steps:

[0015] First, prepare a silicone rubber plug punch that matches the bottom cavity of the multilayer ceramic, and set positioning holes around the silicone rubber plug punch, and the positioning hole passes through the positioning column 6 on the aluminum plate 1 so that the silicone rubber The plug punch is fixed on the aluminum plate 1; then a soft silicone pad 5 for filling is prepared, which is a soft rubber wrapped with a semi-fluid filler, which is made of liquid silicone A and B are mixed at a ratio of 2:1 to obtain a mixture, and then baked at 60-80°C for 1-2 hours to obtain a gel.

[0016] Then, through the process of punching, printing, and cavity opening, the tape-cast green ceramic sheet has positioning h...

Abstract

The invention discloses a molding method of a complicated two-side cavity structure with multilayer ceramics. An elastic semi-fluid soft silicone pad is used as the filling mold of the upper-layer cavity structure, and the male die of a silicon rubber plug of the integral structure is used for filling the bottom-layer cavity structure, thus the molded cavity structure has high precision, is not easily deformed and can be used repeatedly. In addition, the molding method can be used for molding cavity structures with any shape, is easy to process and can guarantee the combination intensity and the gas tightness of the multilayer ceramics and improve the lamination efficiency and cleanability, thereby saving the molding cost.

Description

[0001] technical field [0002] The invention belongs to the technical field of multilayer ceramics with a cavity structure, and in particular relates to a forming method of a double-sided complex cavity structure of a multilayer ceramic. Background technique [0003] The molding of the double-sided cavity structure of multi-layer ceramics currently adopts the filling technology of the shaping mold, combined with the isostatic pressing process, to obtain a ceramic shell with a certain cavity shape, and the shaping mold can choose a metal block or a silicone rubber plug. On the one hand, this method is limited by the mold making, and on the other hand, it is limited by the difficulty in positioning the mold in the double-sided cavity, and it is difficult to ensure the accuracy of the mold position for complex cavities. Whether it is processing a metal block or a silicone rubber plug, it is time-consuming and laborious, and after processing, it can only be used for the moldin...
