Description

TECHNICAL FIELD

[0001] The utility model relates to a novel ceramic hot-pressing casting forming die field, concretely to a cylindrical porous ceramic novel hot-pressing casting forming die. BACKGROUND

[0002] The hot-pressing casting forming die is an important tool used in the hot-pressing casting process, which is usually composed of the following parts: a cavity, which is the core part of the die, is used to form the shape of the product. The shape and size of the cavity determine the appearance and dimensional accuracy of the final product, a gating system, including the sprue, runner and gate, etc., is used to introduce the molten material into the cavity. The design of the gating system should ensure that the material can uniformly fill the cavity to avoid defects, a cooling system is used to control the temperature of the die to ensure that the product can be quickly cooled and solidified during the forming process. The cooling system can use water cooling, air cooling or other cooling methods, and a demolding mechanism is used to take out the formed product from the die. The design of the demolding mechanism should ensure that the product can be smoothly demolded to avoid damage or deformation. Hot-pressing casting is a forming process that heats the powdered or granular material to a molten state, and then injects it into the die under pressure, and the product is obtained after cooling and solidification. The working principle of the hot-pressing casting forming die is as follows: heating the material, heating the powdered or granular material to a molten state to make it flowable, injecting the die, injecting the molten material into the cavity through the gating system under pressure, cooling and solidification, the material injected into the cavity is rapidly cooled and solidified under the action of the cooling system of the die to form the shape of the product, and demolding and taking out, when the product is cooled and solidified, the product is taken out from the die through the demolding mechanism.

[0003] The ceramic hot-pressing casting forming die currently used in the market generally uses spring heating wire threading and whole cavity bottom glue feeding mode, which seriously restricts the work efficiency and causes the spring heating wire to deform during the hot-pressing casting process, affecting the quality, which is not conducive to user use. Therefore, we propose a cylindrical porous ceramic novel hot-pressing casting forming die. Utility model content
