Problems solved by technology

[0002] Existing gravity casting materials can only be formed by using a special casting mold, and the special casting mold cannot be used for production die-casting in a cold chamber die-casting machine, because when the raw material flows into the cavity of the mold, the raw material will generate air bubbles, resulting in Castings often have mold sticking, filling dissatisfaction, pores and shrinkage cavities. Casting molded products cannot meet the requirements of use due to their rough surface. As a result, compared with die casting, the production cost of gravity casting is extremely high, and the production efficiency is very low.

Abstract

The invention provides a die-cast formation die. The die-cast formation die is provided with a die cavity (3), a sprue (1) and a feeding device (11) which is communicated with the sprue (1) and is used for filling raw materials, wherein one end of the die cavity (3) is communicated with the sprue (1) by a transverse pouring gate (2) and the other end of the die cavity (3) is communicated with a riser (5) by an exhausting pipeline (4); the feeding device (11) is connected with numerical control equipment and is used for controlling the speed of injecting raw materials into the die cavity (3) from the sprue (1). By virtue of the die-cast formation die, bubbles in the raw materials can be crushed and the product quality is improved. The invention further provides a die-cast formation method. By adopting the method, the production efficiency is improved and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of die casting, in particular to a die casting mold and a die casting method. Background technique [0002] Existing gravity casting materials can only be formed by using a special casting mold, and the special casting mold cannot be used for production die-casting in a cold chamber die-casting machine, because when the raw material flows into the cavity of the mold, the raw material will generate air bubbles, resulting in Castings often have mold sticking, filling dissatisfaction, pores and shrinkage cavities. Casting molded products cannot meet the requirements of use due to their rough surface. As a result, compared with die casting, the production cost of gravity casting is extremely high, but the production efficiency is very low. Contents of the invention [0003] An object of the present invention is to provide a die-casting mold, which can crush air bubbles in raw materials and improve product quality. [0...
