Embodiment 1

[0021] Embodiment 1, the method for manufacturing thread mouth purple clay cup (cup body is external thread, bowl cover is internal thread) is:

[0022] (1) Zisha cup body / lid forming:

[0023] Put a certain amount of purple sand mud into the mother mold 1 of the mold shown in Figure 1, cover the middle hoop 2, and knock the mold core 3 with an iron or wooden hammer until the mold core 3 is close to the middle hoop 2, and then pull out the mold core 3. Take away the middle hoop 2, and eject the blank with the built-in ejector pin 5 at the bottom of the mother mold 1. The ejector pin 5 built in the bottom of the mother mold is "T" shape, and the "one" part of the ejector pin is placed on the bottom surface of the mother mold 1 , the "丨" part of the ejector rod 5 is inserted into the through hole of the base 6. Since a through hole is punched vertically in the middle of the mold core 3, the through hole at the bottom of the mold core is a bell mouth, and a row is placed in the t...

Embodiment 2

[0028] Embodiment 2, the method for manufacturing thread mouth purple sand cup (cup body is internal thread, cup cover is external thread) is the same as embodiment 1, wherein the forming internal thread cup body adopts internal thread mold, and forming external thread cup cover is external thread mold.

Abstract

The present invention relates to the making process of screw-mouthed purple sand cup / lid and is suitable for mass production. The making process includes forming no-screw purple sand cup / lid with forming molds; forming thread with forming mold possessing inner and outer thread; and baking the matched purple sand cup / lid couple. During formation of thread, the outer thread is formed via demolding mother mold sheets and the inner thread is formed via fixing the balancing and guiding mold and withdrawing mold core. The said making process can make purple sand cup with well matched and watertight lid and suitable for use as tea set, wine set, storage container, etc.

Description

technical field [0001] The invention relates to a purple sand cup / cover, especially a mold for forming a purple sand cup / cover with a threaded mouth, and also provides a method for manufacturing a purple sand cup with a threaded mouth by using the mold. technical background [0002] The traditional purple sand cups on the market, the cup body and the cup cover are generally smooth but close, the disadvantage is that the sealing is poor, and it will leak, especially when the purple sand cup is used as a storage container for wine or other important liquids, the sealing performance is even more critical. Cups, plastic cups, etc., are usually designed to be threaded to solve the problem of water leakage. The cup body usually has external threads, and the cup cover is designed to correspond to internal threads. The internal and external threads of glass cups and plastic cups are easy to form and the process has Mature, but for the purple sand cup with threaded mouth, due to the ...
