Problems solved by technology

[0002] Casting molding is a production method widely used in industry at present. In the structural design of casting molds, gate design is particularly important. Common gate designs include point gates, side gates and spoke gates. In the gate form of the existing casting mold, when the product is small and thin, the product is prone to bonding marks, and even unsatisfactory mold, air bubbles and cracks appear, which reduces the production efficiency and product quality of the product

Abstract

The invention discloses a die casting moulding die which comprises an upper die and a lower die. The upper die is arranged above the lower die, a cavity is arranged at the bottom of the upper die, a mandrel is arranged at a position, corresponding to the center of the cavity, of the lower die, a pouring port is arranged above the cavity, a pouring guide way is arranged above the pouring port, and the cavity is communicated with the pouring port which is communicated with the pouring guide way. By arranging a riser or a cooling layer with a through hole, combining marks and air bubbles of products can be avoided, number of cracking and being not fully moulded of the products is reduced, processing speed of the die can be increased, poured blanks can be cooled at a same time, and product production efficiency and product quality can be improved effectively.

Description

technical field [0001] The invention relates to a casting die, which belongs to the technical field of die design. Background technique [0002] Casting molding is a production method widely used in industry at present. In the structural design of casting molds, gate design is particularly important. Common gate designs include point gates, side gates and spoke gates. In the gate form of the existing casting mold, when the product is small and thin, bonding marks are likely to appear on the product, and even incomplete mold, bubbles and cracks occur, which reduces the production efficiency and product quality of the product. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art, solve the above technical problems, and propose a casting die. [0004] The present invention adopts the following technical scheme: a casting mold, which is characterized in that it includes an upper mold and a lower mold, the upper mo...
