Problems solved by technology

The hollow bottle manufactured by this method cannot guarantee the dimensional accuracy due to the bonding and sintering of several parts, the concentricity is poor, the overlapping parts of the connection are easily broken, and the production efficiency is low.
[0004] In addition, there are some manufacturing methods of hollow objects, which first manufacture the hollow body with symmetrical half-axis directions, and then use local heating to melt the adhesive on the butt joint surface, and press the pressure to bond them into a whole. The process is more complicated, it is difficult to ensure a firm bond

Abstract

The invention provides a method for preparing a hollow object by blow molding of zirconia ceramic. The method comprises: a step 1 of mixing raw materials to prepare slurry; a step 2 of preparing a blank tube, which is to inject the prepared slurry into a corresponding blank tube mold with an injection molding machine, take the blank tube out after the blank tube is solidified and obtain the blank tube; a step 3 of preparing a blank, which is to place the blank tube into a blow molding mold, and form the blank of a circular transition integrated hollow object by blowing under air pressure; a step 4 of degreasing the blank and removing plastic; a step 5 of pre-sintering at a low temperature kept between 1,000 and 1,200 DEG C; a step 6 of detecting and trimming the blank; a step 7 of sintering at a high temperature kept between1,450 and 1,550 DEG C; and a step 8 of cooling to obtain the integrated hollow object. The method has a simple and reliable preparation process, reduces production cost, has high yield and is favorable for industrial mass production, and the prepared hollow object has high size precision and a long service life.

Description

technical field [0001] The invention relates to a method for manufacturing a hollow object, in particular to a method for manufacturing a hollow object by blow molding zirconia ceramics. Background technique [0002] At present, with the improvement of material living standards, people's requirements for products are getting higher and higher. Not only do they require better quality and performance of purchased products, but they also have higher requirements for product packaging and other packaging industries. Therefore, some Such as vases, perfume bottles, cosmetic bottles and other common hollow handicrafts in people's daily life, the production process is also improving day by day. [0003] The manufacturing process of the ceramic bottle in the prior art includes: Step S1: The neck part of the ceramic bottle body is formed by separate rolling, and the blank is trimmed with a tool of precise size, and the part of the bottle mouth is accurately cut off except for the part...
