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 on the figure 1 In the mother mold (1) of the mold shown, cover the middle hoop (2), knock the mold core (3) with an iron or wooden hammer until the mold core (3) is close to the middle hoop (2), and pull out the mold core (3), remove the middle hoop (2), and push out the billet with the built-in ejector pin (5) at the bottom of the mother mold (1). Since a hole is punched vertically in the middle of the mold core (3), there is an exhaust valve in the hole (4), when the mold core (3) is knocked down, the valve is tightly closed by the top of the mud, and when the mold core is pulled out, the blank sucks the valve to allow air to enter, and the mold core is easily pulled out, while the valve is The contact area is very small and can be easily sep...

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. The body and lid of cups and plastic cups are usually designed to be connected by creases to solve the problem of water leakage. The body of the cup usually has external threads, and the lid is designed with corresponding internal threads. The internal and external threads of glass cups and plastic cups are easy to form and the process It has matured, but for the purple sand c...
