Embodiment 1

[0020] Embodiment 1: as figure 1 As shown, the production mold of the glass chopsticks of the present invention is composed of an upper mold 1 and a lower mold 2. A plurality of chopstick-shaped mold cavities 3 are arranged in the mold, and there are communication gaps 4 between the mold cavities 3 .

Embodiment 2

[0021] Embodiment 2: the production technology of glass chopsticks of the present invention comprises:

[0022] (1) Glass raw material smelting: the glass raw material is smelted at 1500°C to make glass slurry for later use;

[0023] (2) Press molding of glass chopsticks: put figure 1 The mold is installed on the hydraulic machine tool, and the mold is in the mold opening state of the upper and lower molds;

[0024] The spare glass slurry is metered and injected into the lower mold 2 of the mold. When the temperature of the glass slurry in the mold cavity 3 cools down to 950°C, the upper mold 1 descends and matches with the lower mold 2 to form a mold clamping; due to the pressure of the upper mold 1, the glass slurry squeezes out. Full cavity 3 and flow gap 4 between cavity 3;

[0025] After 2 seconds of mold closing, the mold is opened, the upper mold 1 rises, and the formed glass chopsticks connected in rows are taken out from the mold cavity 3 with a clamp;

[0026] (3)...

Abstract

The invention discloses a production die and production process for glass chopsticks. The production die for glass chopsticks consists of an upper die and a lower die and is internally provided with a plurality of chopstick type die cavities, and communication clearances are formed among the die cavities; and the production process for glass chopsticks comprises glass melting, glass chopstick pressing and forming, crystallization and annealing treatment, cutting treatment and other steps. For the glass chopsticks made by adopting the die and the process, the product percent of pass is high, the production efficiency is high, and the production cost is low; and the thermal shock resistance of the chopsticks can meet the standard that the chopsticks can be once subjected to heat exchange at 140-20 DEG C without cracking, and the technical indexes of physics, sanitation and the like of the product can all conform to the requirements of the current domestic and overseas glass dinnerware standards.

Description

technical field [0001] The invention relates to glass ceramics, in particular to a production mold and a production process of glass chopsticks. Background technique [0002] Chopsticks are the unique and main tableware of the Chinese nation. Chopsticks are usually made of bamboo or wood, but also silver. Along with the development of industrial technology, the chopsticks that existing materials such as aluminum, stainless steel, pottery, plastics are made appear. Chopsticks need to be used repeatedly, which involves cleaning and disinfection after use. Bamboo and wooden chopsticks that are used repeatedly are prone to mold or residual bacteria, and consume a lot of bamboo and wood resources; aluminum and stainless steel chopsticks are prone to heat conduction and heat storage, which is unsafe and uncomfortable to use; plastic chopsticks are used in hot environments. It is easy to deform, volatilize harmful substances, and is not suitable for high-temperature disinfection...
