AI Technical Summary

Technical Problem

In existing mold production, it is difficult to perform arc-shaped grinding on the inner wall of the concave part of the grinding operation of the toothed mold. In particular, the diameter of the top of the concave part is small and the teeth on both sides restrict it, which makes it impossible for the grinding head to enter, affecting production efficiency and quality.

Method used

By combining 3D printing and grinding, concave teeth and grooves are first formed on the mold blank by grinding head, and then convex teeth and convex strips are printed by 3D printer head. Combined with the adjustment of the mounting base, the inner wall of the concave part is ground and polished, increasing the grinding activity space and avoiding the restriction of convex teeth.

Benefits of technology

It improves the precision and integrity of concave tooth grinding, ensures the forming quality of mold blanks, enhances the working space of the grinding head, solves the technical problem that traditional grinding heads cannot enter the inner wall of the concave part, and realizes the efficient production of complex molds.

Abstract

The application discloses a production method and a mold of a silica gel bag mold, and the mold blank can be subjected to forming operation on each part on the mold blank through a 3D printing and grinding combined mode, so that the mold blank can be subjected to grinding and polishing on the concave teeth, the first groove and the second groove first, and then subjected to printing and polishing on the convex teeth, the first convex strip, the second convex strip and the third convex strip, which is favorable for the grinding tool head not to be subjected to the convex teeth, the first convex strip, the second convex strip and the third convex strip in the grinding process, so that the grinding tool head can have a larger movement space on the mold blank when the mold blank is movably matched, the angle change of the grinding tool head in the grinding process can be increased, the grinding tool head is favorable for grinding and polishing the arc inner wall of the concave teeth through the opening at the top of the concave teeth, and the precision of the grinding tool head in the grinding process is improved.
