Problems solved by technology

However, these existing technologies have little effect on solving the shrinkage porosity and shrinkage cavity formed by the internal shrinkage of die castings.
The existence of shrinkage cavity and shrinkage porosity usually greatly reduces the mechanical properties of castings

Abstract

The present invention designs an anti-shrinkage cavity die-casting mold, which includes a fixed mold base plate and a movable mold base plate. There is a die-casting cavity forming a die-casting part between the fixed mold cover plate and the movable mold cover plate. The die-casting mold A spherical riser is arranged beside the cavity, and a sprue is arranged on the spherical riser, and the sprue is connected with the gate, and the sprue is arranged on the fixed mold seat plate, and the spherical riser is arranged on the die casting next to the thickest part. An extrusion hole communicated with the die-casting cavity is arranged on the fixed mold cover plate and the fixed mold fixed plate, and an extrusion punch is arranged in the said extrusion hole. In the anti-shrinkage cavity die-casting mold of the present invention, aiming at the causes of shrinkage cavity and shrinkage porosity, a spherical riser is arranged beside the thick part of the casting. The head is extruded toward the wall thickness of the product, which plays the role of feeding and compacting, effectively solving the problems of shrinkage cavity and shrinkage porosity of castings, and improving the quality of castings.

Description

technical field [0001] The invention relates to the field of die-casting production of auto parts, in particular to an anti-shrinkage cavity die-casting mold. Background technique [0002] Die casting is a fast-growing metal forming precision casting method with high efficiency and less cutting in modern metal processing technology. Die castings have high dimensional accuracy, low surface roughness values, and high strength and hardness. Due to the above advantages, the die casting process has been widely used in all walks of life in the national economy. In addition to being used in automobiles and motorcycles, instruments, and industrial appliances, die castings are also widely used in household appliances, agricultural machinery, radio, communications, machine tools, transportation, shipbuilding, cameras, clocks, computers, textile equipment and other industries. Among them, the automobile and motorcycle manufacturing industry is the most important application field, wi...
